▼ Background: Comorbidity has an important impact on cancer outcomes, but the optimal approach to measuring comorbidity at a population level has not been established.
Aims:
• To review evidence relating to the importance of comorbidity in relation to cancer care and outcomes; and to examine previously developed approaches to measuring comorbidity in this context.
• To assess the usefulness of routinely collected comorbidity
data in New Zealand,
• To develop and validate optimised measures of comorbidity using these
data for patients with cancer,
• To develop, and compare more simplified measures against the optimised measures.
Methods: Studies describing methods to measure comorbidity in epidemiological studies related to cancer were identified and reviewed. For this study, development and validation cohorts included patients diagnosed with colorectal, breast, gynaecological, upper gastrointestinal, or urological cancers identified from the national Cancer Registry between July 2006 and June 2008 for the development cohort (n=14096) and July 2008 to Dec 2009 for the validation cohort (n=11014).
Data on comorbid conditions identified in
administrative hospitalisation and pharmaceutical
data were compared with
data from manual clinical notes review for a subset of patients. Fifty conditions using
administrative hospitalisation and twenty conditions using pharmaceutical
data were identified prior to cancer diagnosis. Three sets of indices were developed 1) site-specific indices using hospitalisation
data (‘C3’ indices), 2) a single all-cancer index using pharmaceutical
data (PBCI) and 3) three simplified versions of the hospitalisation indices; an all-cancer version and two versions including a subset of conditions (SI1, 2 and 3 respectively). Conditions were weighted according to their log hazard ratios from age and stage adjusted Cox regression models of non-cancer death; and indices were calculated by summing these weights. Performance of these indices was compared with the Charlson index, a combination of the C3 and pharmacy-based indices, and with each other.
Results: The review of previously developed comorbidity measures for cancer populations identified 21 separate approaches, with none identified as gold standard.
Administrative data were found to be adequate for measuring comorbidity in cancer populations. Comorbidity was associated with poorer survival but the impact varied by condition and across cancer site. No single index clearly outperformed all others for all sites. The best performance overall was achieved with the combined hospitalisation and pharmaceutical indices, particularly for all sites combined, colorectal and upper GI cancers. Generally hospitalisation indices outperformed the pharmaceutical-based index, but the converse was true for non-cancer death for breast and gynaecological cancers. Site-specific weights did not add appreciably to the validity of the indices. Among the simpler indices, the SI2, SI3 and PBCI approaches tended to outperform the Charlson index for all…

▼ Introduction: The main objective of this thesis is to develop an algorithm to accurately identify cases of biopsy-proven Celiac Disease (CD) in children aged 6 months-14 years old from Ontario health administrative data.
Method: CD cases diagnosed in 2005-2011 were identified from CHEO, and linked to the health administrative data to serve as reference for algorithms derivation. Algorithms based on outpatient physician visits for CD plus endoscopy billing code were constructed and tested.
Results: The best algorithm selected based on performance from derivation study and clinical expertise consisted of an OHIP-based endoscopy billing claim followed by 1 or more adult or pediatric gastroenterologist encounters after the endoscopic procedure. The sensitivity, specificity, PPV, and NPV for the algorithm were 70.4%, >99.9%, 53.3% and >99.9% respectively.
Conclusion: Study results suggest that the currently available Ontario health administrative data is not suitable for identifying incident pediatric CD cases.

▼ Introduction: Pharmaceutical cannabinoids are third-line therapeutic options for several indications, despite the lack of strong evidence to support their efficacy. The extent and patterns of their utilization from a population perspective are unknown.
Methods: A retrospective population-based study using
administrative healthcare
data from Apr.1, 2004 to Mar.31, 2017, to assess the annual trends, demographic and clinical determinants, and persistence of pharmaceutical cannabinoids use.
Results: The incident and prevalent users of cannabinoid agents increased throughout the study period. Nabilone comprised the majority of dispensations. The percent of users who had a diagnosis for the approved indications was relatively low. Persistence of cannabinoid use was low and influenced by the socio-demographics and medical conditions of users.
Conclusion: Although the rates of pharmaceutical cannabinoid use have increased, the overall low numbers of users and the high discontinuation rates reflect the lack of effectiveness and tolerability to these agents.

▼ Background: Research into Colorectal cancer (CRC) require maintenance of clinical cancer databases with complex datasets. These are resource intensive, region specific, and compromised by reporting bias [1]. Administrative data are routinely captured for each hospital admission and may serve as an alternative source for populating databases. However, the accuracy of administrative data has not been fully explored and may vary by data item. The aims of this study included identifying a cohort of new CRC patients from administrative data, measuring its accuracy, and deriving coding algorithms to improve the accuracy of diagnoses, procedures and short-term outcomes.
There has been much debate that major surgery, in particular for cancer patients, should be concentrated in tertiary centres, based on the premise that high volume centres achieve better outcomes. In this study, we investigated two hypotheses: that the majority of complex colorectal cancer resections are performed in major city hospitals and that the short-term outcomes are better in CSSANZ (Colorectal Surgical Society of Australia and New Zealand) hospitals.
Large Inpatient administrative databases are a common source used to identify comorbidities recorded with International Classification of Disease (ICD) diagnostic codes. These data sources may be used to assess the effect of baseline comorbidity status on surgical care outcomes. In this study, we hypothesized that the ASA PS (American Society of Anaesthesiologists physical status) classification can predict short-term outcomes after a colorectal cancer resection when compared to the Elixhauser comorbidity index (ECI).
Methods: A retrospective study was conducted to identify all new colorectal cancer resections at The Royal Melbourne Hospital from 1st of January 2008 to 31st of December 2013, using administrative data. Code combinations and algorithms were used to improve the accuracy of administrative data.
These algorithms were utilized to identify an accurate cohort of colorectal cancer resection cases from the Victorian Admitted Episodes Dataset (VAED), between July 2008 to June 2013. The short-term outcomes and workloads were compared in public hospitals across the state of Victoria.
The algorithms constructed were also utilised to identify an accurate cohort of CRC resection cases from Dr Foster Global Comparators Victorian dataset. ASA PS classification scores were identified from these cases. Multiple linear regression models were constructed to study the association between comorbidity indices and short-term outcomes.
Results: It is possible to use administrative data to identify new colorectal cancer patients who have had a surgical resection, using specific coding algorithms. Administrative data has an accuracy of 80-100% for most data fields, and this accuracy can be improved using coding algorithms.
An accurate cohort of colorectal cancer resection cases was identified from the VAED dataset. Seventy-three percent of CRC resections in the state were performed in…

▼ Increasingly, migrants and health are major international concerns and an important area of study within public health. The recent increase in rates of migration and the vast differences between demographic and socioeconomic characteristics of most migrant groups compared to settled populations are known to be some of the main reasons for the increasing need to focus research efforts on migrant health. However, despite the increasing availability of accessible national datasets, very few register-based studies have been conducted in the UK, especially when compared to other regions in Europe (most notably the Nordic countries), and worldwide. This thesis aimed to evaluate the usefulness of administrative data in the research of migrant health. A scoping review of the literature revealed that migrants were less likely to utilise mental healthcare services and access psychotropic prescription medication than the settled majority population in their new countries. In addition, mental ill-health prevalence and suicide rates were higher amongst the migrant population. The advantages and disadvantages of using administrative data in migrant mental health research are discussed, as informed by the studies included in the review. In order to profile the migrant population of Northern Ireland, and to investigate the mental health of the migrant population as compared to the settled majority population, records from the 2011 Census of Northern Ireland were linked to psychotropic prescribing information from the Enhanced Prescribing Database. Migrants were significantly less likely to report poor mental health than the settled population of Northern Ireland, when adjusted for demographic characteristics, socioeconomic factors, and reported poor physical health. Migrants were also significantly less likely to use any form of psychotropic prescription medication than the settled population. A further study was conducted in Finland. The National Finish Population Register was linked with the Finish National Death Register in order to compare the mortality risk of migrant groups in Finland with the settled Finnish majority population. Results showed that particularly low-income migrants seem to display a survival advantage compared with the corresponding income group in the settled majority population. The thesis uses administrative data from two European countries to assess migrant health. It also appraises the administrative data available in both countries. With increasing rates of world-wide migration, and increasing awareness of mental health difficulties, this thesis should be of particular interest to policy makers; the findings could help guide improvements in the way that administrative data is collected to better encapsulate migrant populations.

▼ End-of-life (EOL) care in the United States is costly, highly fragmented, and uncoordinated. Despite devoting almost one third of all Medicare expenditures to caring for patients during their last year of life, studies have repeatedly shown that the overall quality of care and quality of life at the EOL is poor. In order to provide better quality care at the EOL, it is crucial that we have a solid understanding of how EOL care is provided under our current healthcare system. This dissertation uses two large administrative datasets to explore and explain variations and patterns in the care patients receive at the EOL and contains three papers. Paper one explores the variations in the use of life-sustaining treatments before death. Paper two examines the impact the organization of our healthcare system has on the use and underuse of hospice services among patients in long-term care hospitals with chronic critical illness. Paper three explores the power of financial incentives in the form of Medicare reimbursements in influencing providers' decision on discharging patients from long-term care hospitals. In this work, we showed that patterns of care near the EOL are highly variable across subgroups of patients, provider institutions, and geographic regions; and are heavily influenced by financial incentives as well as the supply of healthcare providers. More importantly, this dissertation illustrates the urgent need to develop new and expand on existing data sources with the relevant information required to gain a more in-depth understanding of what is driving the differences in care in order to deliver true patient-centered and family-oriented care near the EOL.

▼ Since there is a limited literature base concerning individuals admitted with a potentially preventable hospitalization (PPH) who acquired a healthcare associated infection (HAI), this research identified the prevalence and costs of individuals admitted to Texas hospitals in 2011 for a PPH and acquired an HAI. Based on IOM identified associations between PPH and uninsurance, the analytic evaluation draws from theoretical models that link insurance status to outcomes such as PPH. Using the hypothesis that the cost of preventive care for the uninsured with ambulatory care sensitive conditions (ACSC) that lead to PPH would be less than the incremental cost of healthcare for HAI in individuals admitted with a PPH and acquired an HAI, I estimated costs for ACSC related preventive care, PPH, and the incremental cost of HAI. The Agency for Healthcare Research and Quality (AHRQ) Quality Indicator modules identified PPH using
administrative inpatient discharge
data and private insurer claims
data. Adjusting for demographic, community and hospital characteristics, logistic regression analysis estimated odds ratios of PPH individuals acquiring an HAI, and generalized least squared regression estimated costs needed to address the hypothesis. I identified 1,031 individuals in the 2011 Texas inpatient discharge
data with both a PPH and an HAI. 66% of the PPH with HAI population identified Medicare as their primary payer, and 7% identified Self-pay or Charity as primary payer. Most PPH individuals had lower odds of acquiring an HAI. However, individuals admitted with diabetes related lower extremity amputation demonstrated a significantly higher odds of acquiring either Clostridium difficile infection (OR: 2.9, CI_(95%) 2.16, 3.91) or ventilator associated pneumonia (OR: 1.4, CI_(95%) 0.95, 2.18). The adjusted mean cost per hospitalization for PPH was approximately 2,000 less than the general inpatient population. The estimated incremental cost of HAI for the 97 uninsured individuals in the PPH and HAI population was 2.1 million. The cost of preventive healthcare for uninsured individuals in Texas with an ACSC was estimated at 66.8 billion. Given the large proportion of insured within the PPH with HAI population, and the incremental cost of HAI quantified, I recommend additional research focusing on the Medicare population affected.

▼ Following the passage of No Child Left Behind (NCLB) in 2002, the pressure on school administrators to collect, analyze and report educational
data in meaningful ways became greater than ever before (Gerwetz, 2006). As NCLB now fades into the distance pushed aside by the law's successor, the Every Student Succeeds Act (ESSA) of 2015, state legislators and policy makers are working through new assessment and
data criteria for public schools. The understandings and impact of
data-driven decision making (DDDM) on local school systems remains relevant as ESSA requires states to continue disaggregating
data by student sub-group and in support of student growth.
School administrators are under enormous pressure to show patterns of growth for all students. DDDM has been a widely utilized technique in managing school operations, charting student growth and helping plan reform. What has evolved post-NCLB is the emergence of DDDM tools and techniques to help guide and inform initiatives designed to improve schools. This growth is supported by a publishing industry that produces "how-to" books and articles for school leaders on applying DDDM. Much of the research done on DDDM has focused largely on the technical and structural dimensions of
data use with less attention paid towards administrators'' perceptions of DDDM and how school administrators are utilizing DDDM to strategically frame a culture of continuous improvement. Research has focused on systems built around compliance to mandated accountability models but often not based on the conviction of school administrators in support of a culture of continual learning and growth. Under ESSA, how will DDDM be viewed and utilized by school administrators?
This qualitative research study focuses on the concept of DDDM and school administrators' perceptions of this concept in their school district. 24 school administrators from nine distinct school districts were interviewed for their reactions regarding DDDM. Is DDDM supporting student centered school improvement work based on conviction, or has the concept supported the distortion of a compliance driven educational process?

▼ This dissertation involves three studies that assess law enforcement related injuries and fatalities in the United States. The first study takes advantage of injury surveillance
data collected by the Centers for Disease Control and Prevention to assess injuries and deaths caused by law enforcement. The second project is an analysis of two probabilistically linked
administrative databases that included two medically treated patient groups who had either been injured or killed by law enforcement or by civilians in Illinois. The third project is an analysis of the cause, severity, and workers’ compensation pay out among Illinois law enforcement personnel.
The first study found that legal intervention fatality rates increased over time. Black men had much higher injury and fatality rates than other racial groups. American Indian/ Alaskan Natives were found to have much higher fatality rates than the national average. One recommendation is to create a national code of conduct manual for civilians that can be used as a directive for what to do when interacting with police officers.
The second study found that most civilian assaults occurred before the age of 35 but legal interventions continued to age 44. Legal intervention injuries had more severe outcomes such as longer hospital stays, higher severity scoring, and more comorbid and psychiatric conditions than in those injured by civilian assaults. Injuries caused by legal interventions may not be due to interactions between law enforcement and civilians during the arrest process.
The third study found that the causes of occupational injuries included assault, falls, motor vehicle accidents, and overexertion, among other causes. Extremities account for a high proportion of body parts affected by injury among officers. Additionally, correctional officers represented 45% of all disputed claims filed over the study period, and state police had a significantly higher proportion of officers who represented themselves. State police had some of the lowest compensation payouts and a much wider range of compensation. There lies a disparity in disputed claims among correctional officers that is not well understood, injury and fatality research on police should be assessed by department type, and safety recommendations should vary by department.

▼ This thesis is comprised of three essays relating to long term unemployment in Spain. The first chapter is methodological analysis of the main dataset that is used throughout the thesis. The second and third chapter provide two applications of the dataset for the study of long term unemployment. The methodology in these chapters can be easily adapted to study unemployment in other countries. Chapter 1. On the use of administrative data for the study of unemployment Social security administrative data are increasingly becoming available in many countries. These are very attractive data as they have a long panel structure (large N, large T) and allow to measure many different variables with higher precision. Because of their nature they can capture aspects that are usually hidden due to design or timing of survey data. However, administrative data are not ready to be used for labour market research, especially studies involving unemployment. The main reason is that administrative data only capture those registered unemployed, and in some cases only those receiving unemployment benefits. The gap between total unemployment and registered unemployment is not constant neither across workers characteristics nor time. In this paper I augment Spanish Social Security administrative data by adding missing unemployment spells using information from the institutional framework. I compare the resulting unemployment rate to that of the Labour Force Survey, showing that both are comparable and thus the administrative dataset is useful for labour market research. I also explore how the administrative data can be used to study some important aspects of the labour market that the Labour Force survey can’t capture. Administrative data can also be used to overcome some of the problems of the Labour Force survey such as changes in the structure of the survey. This paper aims to provide a comprehensive guide on how to adapt administrative datasets to make them useful for studying unemployment. Chapter 2. Unemployment Duration Variance Decomposition `a la ABS: Evidence from Spain Existing studies of unemployment duration typically use self-reported information from labour force surveys. We revisit this question using precise information on spells from administrative data. We follow the recent method proposed by Alvarez, Borovickova and Shimer (2015) for estimating the different components of the duration of unemployment using administrative data and have applied it to Austria. In this paper we apply the same method (the ABS method hereafter) to Spain using Spanish Social Security data. Administrative data have many advantages compared to Labour Force Survey data, but we note that there are some incompleteness that need to be enhanced in order to use the data for unemployment analysis (e.g., unemployed workers that run out of unemployment insurance have no labour market status in the data). The degree and nature of such incompleteness is country-specific and are particularly important in Spain. Following Chapter 1, we deal with these data…

▼ Introduction:
Administrative health databases are important resources for population-based chronic disease research and surveillance, but case definitions to identify disease cases can have low sensitivity and specificity. Case definitions constructed using repeated measurements of diagnoses over time have potential for improved accuracy. In particular, dynamic classification, which uses probabilistic models to classify individuals into disease, non-disease, and indeterminate categories and then updates these classifications as new information becomes available, are promising alternatives to conventional static classification methods for case ascertainment.
Purpose & Objectives: The research purpose was to develop and evaluate methods that use longitudinal diagnostic information from population-based
administrative databases to improve the accuracy of chronic disease case definitions. The objectives were to: (1) develop dynamic classification methods for retrospective longitudinal
administrative data, (2) apply and validate dynamic classification to identify cases of juvenile arthritis (JA), and (3) compare the performance of case definitions developed using dynamic classification with case definitions developed using static approaches for classification.
Methods: Dynamic longitudinal discriminant analysis (LoDA) was adapted for retrospective longitudinal
administrative data and applied to
administrative health
data from Manitoba to identify cases of JA. The Pediatric Rheumatology Clinical Database was used for validation. Performance of the JA case definitions constructed with dynamic LoDA was measured using sensitivity, specificity, positive predictive value (PPV), and mean time to classification. Classification accuracy was compared for dynamic LoDA, deterministic case definitions and static LoDA models.
Results: The study cohort included 797 children from the clinical database who could be linked to
administrative health
data from birth to age 16; 386 (48.4%) were JA cases and 411 (51.6%) were non-cases. The dynamic LoDA model with the best fit used a longitudinal binary variable for any-JA related physician visit or hospitalization. It had sensitivity of 0.70, specificity of 0.81, PPV of 0.82, and left 2% of the cohort unclassified after all
data were used. On average, it took 9.21 years of
data to classify individuals as a JA case or non-case. Both the deterministic case definition and static LoDA model outperformed the best dynamic LoDA model.
Conclusion: The results suggest that dynamic classification can produce accurate case definitions using longitudinal information from
administrative health
data, although the choice of methods and their comparative performance will depend on the characteristics of the disease.

▼ Patients with cancer have complex care requirements that may result in an emergency department (ED) visit. In this retrospective cohort study, Ontario health databases were used to identify 42,820 qualifying patients who received chemotherapy or radiation in the 30-days prior to a cancer-related ED visit. Using multivariable models and propensity score matching, odds of hospitalization were lower in patients treated at alternative EDs compared to original EDs, but there was no difference in mortality, return ED visits or CT imaging. For patients seen at an alternative general hospital, the adjusted odds of hospitalization were again lower when compared to patients seen at original hospitals/cancer centres, but 30-day mortality and return ED visits were higher and CT imaging was lower. The results of this study suggest that the cancer expertise of an institution, rather than continuity of care, may be an important predictor of outcomes following emergency treatment of cancer patients.

▼ The purpose of this study was to investigate how routine, day-to-day public health nursing (PHN) practice in one BC health authority affected health outcomes related to breastfeeding initiation and duration, infant immunizations, and household tobacco use within the population of perinatal women who were a high priority for additional and ongoing PHN services. Using
administrative data from the integrated public health information system (iPHIS), outcomes for the priority population were compared to those of the general population of new mothers receiving usual PHN services. Additionally, through semi-structured interviews with PHNs, this study explored how the context of the work environment influenced PHN practice, and ultimately the achievement of those outcomes. Based on a philosophical foundation of critical realism, and a theoretical framework of critical caring, a mixed methods case study design was used to study PHN practice, as it existed day-to-day, amidst the array of ever changing organizational influences.
Results from the statistical analysis of
administrative data and thematic analysis of PHN interviews and organizational guiding documents, showed that priority women, who received five or more postnatal contacts from PHNs initiated breastfeeding in higher proportions than non-priority women, and continued breastfeeding to 18 months in the same proportion as non-priority mothers. Rates of breastfeeding duration for priority women were higher than expected based on current literature. Children of priority mothers were fully immunized in a slightly higher, but not significantly different proportion than children of the non-priority population, also at rates higher than expected. Although high rates of household tobacco use among this group of priority women did not appear to be influenced by PHN contact, the relationships that developed between priority women and PHNs suggest that organizational support for tobacco cessation activities may be a missed opportunity. Thematic analysis of PHN interviews and guiding documents provided background context and clarification for the kinds of organizational factors and underlying mechanisms that may have influenced the ability of PHNs to provide additional and ongoing support to priority perinatal women in achieving these three outcomes of interest. Finally, the theory of critical caring was verified and extended through the experiences and explanations of PHNs, with the addition of “navigating organizational complexity” to the original seven carative health promoting processes.

▼ Title: Outcomes in Patients With and Without ICD-9 Diagnosed Severe Sepsis and Septic Shock Purpose: To evaluate the hypothesis that patients who present to the emergency department with objective findings of severe sepsis or septic shock, but who are not specifically diagnosed, denoted by absence of 995.92 or 785.52, are treated less aggressively and have worse outcomes than similar patients who are specifically diagnosed with severe sepsis or septic shock. Design: Retrospective cohort study Setting: University of Kansas Hospital, academic medical center, emergency department Patients: 6885 patients with severe sepsis or septic shock Methods:
Data were extracted from the electronic health record using the query tool HERON, to identify patients with severe sepsis or septic shock admitted through the emergency department, between 11/01/07–09/31/15. Patients aged ≥ 18 years, who had an infection, received an antibiotic ≤ 8 hours after triage, and meet criteria for severe sepsis and/or septic shock were eligible for inclusion. Severe sepsis was defined either by explicit diagnosis, ICD-9 995.92, or clinical criteria, infection + ≥2 sites of organ dysfunction. Septic shock was identified by one of the following: 1) an explicit diagnosis of septic shock, ICD-9 785.52, 2) criteria for severe sepsis and an ICD-9 code of other shock or shock unspecified (785.50 or 785.59), or 3) criteria for severe sepsis and received a vasopressor. We compared treatment rates, based on the Surviving Sepsis Campaign three-hour recommendations, and outcome differences between severe sepsis and septic shock patients who had a diagnosis code of 995.92 or 785.52 to patients who met criteria, but were never diagnosed as denoted by no ICD-9 diagnosis code. Main Results: A total of 6885 eligible patients were identified, with a mean age of 60.4 years ± 16.9 (mean ± standard deviation). Half of patients were male, (51.3%) and 42.5% received an ICD-9 diagnosis code of 995.92 or 785.52. Septic shock was coded more frequently than severe sepsis (74.1% vs 32.8%). Three-hour bundle protocol completion rates were low for all patients (8.6%), but higher for those with an ICD-9 code than patients without (9.6% vs 7.9%, p=0.02). Average time to first antibiotic administration was also earlier for those with a diagnosis code (3.2 ± 3.1 hours vs 3.93 ± 3.9 hours, p <0.001). Therapeutic components of the 3-hour protocol, administration of an antibiotic and IV fluids if needed, were also found to be administered more often in patients with a diagnosis code (34.8% vs 28.6%, p<0.001). Within the cohort, 5631 (81.7%) patients had severe sepsis and no shock. Those with an ICD-9 code of 995.92 had higher mortality (6.3% vs 2.3%), higher ICU admission rates (44.7% vs 22.5%), and hospital lengths of stay (9.2 ± 6.9 days vs 6.9 ± 6.7 days), (all p<0.001). Discharge locations were also different. Severe sepsis patients with an ICD-9 diagnosis code were discharged home less (43.6% vs 52.0%, p<0.001), were discharged to hospice more (6.1% vs 4.4%, p<0.001), and were given…

▼ Higher education has increasing importance to our
economic and social well-being. Dual enrollment is a policy tool
used to encourage high school students to pursue, persist, and
succeed in higher education by smoothing students’ transition from
high school to higher education. Although there is a growing
literature seeking to measure the impact of dual enrollment on
students’ higher education outcomes, it suffers from limited
generalizability and a lack of theory to explain its potential
impact. Because dual enrollment is growing in popularity with the
expectation that it will improve students’ higher education
outcomes, this dissertation seeks to both understand dual
enrollment’s underlying theory and measure its impact on Ohio’s
students.This dissertation explores theories of emerging adulthood,
anticipatory socialization, and role rehearsal in framing the
possible mechanisms by which dual enrollment may benefit students.
I empirically explore the state-wide impact of College Credit Plus,
an Ohio law that requires school districts to offer dual enrollment
at no charge to students. Using a synthetic comparison group, the
impact of College Credit Plus on Ohio students’ higher education
enrollment is uncertain, but the impact on persistence in
enrollment from year one to year two is larger than an Ohio
synthetic comparison state without College Credit Plus.Next this
dissertation includes a descriptive analysis of dual enrollment in
Ohio. Participation increases steadily until College Credit Plus
was enacted, at which point participation increase more quickly.
One goal of College Credit Plus is to diversify higher education in
Ohio; findings show that dual enrollment participation is lower
among underrepresented groups, and the gap is growing. A different
strategy is then employed to model dual enrollment outcomes using a
fixed effects model of school districts. This model measures the
relationship between dual enrollment participation among each
graduating cohort, and the rate at which that cohort enrolls in
college after graduation, and whether they persist from year one to
year two. The fixed effects model allows these outcomes to be
modeled controlling for time-invariant characteristics of the
school district. The results provide evidence that increasing the
dual enrollment participation in a school district does in fact
increase the proportion of students subsequently enrolling in
higher education, as well as persisting into year two. The results
hold up in subsets of districts that have high proportions of
economically disadvantaged students and those that have high
proportions of Black students.These studies provide compelling
evidence that dual enrollment is associated with improved higher
education enrollment and persistence. Where underrepresented groups
of students participate in dual enrollment, evidence shows it is a
successful strategy in improving their higher education outcomes as
well.

▼ The goal of this thesis is to develop inferential procedures with non-probability survey samples. In recent years, the use of non-probability survey samples has become one of the most important topics in the area. Contrast to the burdensome process of obtaining probability samples, non-probability survey samples, empowered by the information technology, can be acquired through the internet and other convenient measures timely and efficiently. These prompt and affordable data have facilitated online researches for both academic and industrial uses.
Nevertheless, non-probability survey samples are biased samples, from which no valid inferences about the target population can be obtained immediately. A popular tool for bias correction is the propensity score associated with each unit in the population, which is defined as the probability of selection conditional on observed auxiliary variables. Propensity scores need to be estimated in practice, but existing estimation methods are mainly derived on an ad hoc basis. This thesis establishes a general framework for statistical inferences with non-probability survey samples when relevant auxiliary information is available from a reference probability survey sample. Under this framework, we develop a rigorous procedure of estimating propensity scores. The main idea of the procedure is to approximate the required but unknown population-level information by its estimate based on the reference sample. Given the estimated propensity scores, we further present two parallel approaches to estimate the finite population mean: the quasi-randomization (QR) approach and the pseudo-empirical likelihood (PEL) approach. Moreover, the potential issue of zero propensity scores is highlighted and investigated.

▼ Section 16 A (2) (d), (e) and (f) of the South African
Schools Act, Act 84 of 1996 assumes that a school principal has
specialised knowledge in interpreting legislation, dealing with
disciplinary matters pertaining to learners, educators and support
staff, and making disciplinary decisions. The legal framework of
the Promotion of
Administrative Justice Act, Act 3 of 2000, as well
as section 33 of the Constitution of the Republic of South Africa,
Act 108 of 1996, affects disciplinary decision making in education.
The need to understand how legislation affects disciplinary
decision making is important, because s ection 16 A of the South
African Schools Act, Act 84 of 1996 assumes that education managers
have the requisite knowledge and understanding of the law when
dealing with disciplinary decision making. Disciplinary decisions
taken by education managers fall in the domain of
administrative
law. The Promotion of
Administrative Justice Act, Act 3 of 2000,
forms the foundation for
administrative action that is lawful,
reasonable and fair. Since this Act is relatively new, and
education managers have a lack of education law knowledge in
general, it can be argued that principals might struggle to take
disciplinary decisions that are lawful, reasonable and fair. Thus,
there is a need to answer the following question: What are the
legal requirements that should be considered in taking disciplinary
decisions that are lawful, reasonable and fair and how can these
disciplinary decisions be made more effectively?
The purpose of
the study was to understand the context and content of Section 33
of the Constitution of the Republic of South Africa, Act 108 of
1996, the Promotion of
Administrative Justice Act, Act 3 of 2000,
and Section 16A of the Schools Act , Act 84 of 1996 and how they
would positively influence disciplinary decision making in South
African education. The main research question was: What are the
legal requirements that should be considered in taking disciplinary
decisions that are lawful, reasonable and fair and how can these
disciplinary decisions be made more effectively?
Chapter 2
answered the research question of which decision-making processes
could assist the education manager to take disciplinary decisions
that are lawful, reasonable and fair. It was established that
principals make frequent use of the rational model for decision
making. However, the more comprehensive
data-driven decision-making
model was proposed. This not only focuses on a single disciplinary
decision, but on the cause and trends of all transgressions that
exist in a school. This model enables a principal to draw up a plan
of action to deal with the cause of the problem.
After analysing
the applicable legal framework, the concepts of lawful, reasonable,
and fair were defined and interpreted in Chapter 3. An
administrative action is lawful when an administrator is duly
authorised by law to exercise power. Reasonableness has two
elements, namely rationality and proportionality. Rationality means
that evidence and information should…

▼ Since local governments in Taiwan were given the power of self governance
in 1950, the
administrative divisions havenât been readjusted. After 60-year development, the population distribution and urban modes have totally changed. Without readjustment of the
administrative divisions, human resource could not be reasonably deployed, resources wasted, regional development gaps widened and the entire country development was severely influenced. Under the impact of globalization and in response to new development in all aspects, such as politics, economics, society and territory, the governmental system and function have to be re-defined and
administrative divisions and organization structure have to be readjusted to build an idealized and high-effective government. In recent years, local self-governing groups around the world also moved on to merging to cope with local fiscal predicament and promote the empowerment of local governing groups to enhance their
administrative ability. The academic also comprehend the urgent importance of the merging of urban and rural townships and thus propose different resolution projects and strategies and directions of merging and adjustment.
The author managed to sort different literature into supporting theories of merging and foreign cases about the merging of local self-governing groups. Based on the above theories and cases and through
data envelopment analysis (DEA), the author simulated different merging programs of urban and rural townships, compared the efficiency before merging and that after merging, and proposed concrete suggestion towards the inefficient self-governing groups. The result showed that the program of merging urban and rural townships could increase the efficiency in every aspect. The conclusion can serve as reference to the future implement of the program of merging urban and rural townships.

▼ Blood sampling causes significant blood loss in intensive care unit (ICU) patients (up to 41 mL per day). Only 10% of the blood collected is used for testing suggesting that volumes can be reduced without compromising patient care or laboratory processes. Blood loss contributes to anemia which is highly prevalent in the ICU (>90% after 3 days) and is associated with major adverse cardiovascular outcomes and death.
Diagnostic blood loss increases the likelihood of red blood cell (RBC) transfusion which is administered to about 40% of ICU patients (half are given in absence of hemorrhage) and has significant health risks. Small-volume blood collection tubes, which collect about 50% less blood, are available, but rarely used in adults. They have the same cost as standard-volume tubes and are compatible with laboratory equipment. The rationale for the continued use of standard-volume tubes is a theoretical concern about inadequate volume for testing, and the absence of data showing the benefit of small-volume tube use on an important clinical outcome.
A study is needed to show that small-volume tubes reduce blood loss, anemia and RBC transfusion without harms or negative consequences on patient care and hospital procedures compared to standard-volume tubes. If this could be shown, it may lead to practice change regarding blood collection for laboratory testing. A stepped-wedge cluster randomized trial is the ideal study design for this low-risk intervention. By incorporating the small-volume tubes into routine clinical practice and using administrative and hospital electronic medical record data, this study would be a pragmatic, cost-effective way to evaluate effectiveness and implementation. However, prior to conducting a full-scale trial powered on clinical outcomes, a pilot study is needed to determine whether a larger study will be feasible.
The goals of this thesis are to (i) summarize the existing evidence regarding small-volume tubes; (ii) discuss cluster randomized trial methodology;(iii) discuss the use of health care administrative data for research; (iv) discuss the role of pilot studies; and (v) present the design of a pilot stepped wedge randomized trial of small-volume versus standard-volume blood collection tubes to evaluate the feasibility of a full-scale trial.
Thesis
Master of Science (MSc)
Blood testing is a preventable cause of blood loss. Patients in the intensive care unit (ICU) have about 41 mL of blood taken per day for testing (like donating 1 unit of blood every 8 days). This contributes to anemia (low red blood cells) and transfusion, which are harmful. About 40% of ICU patients get at least one red blood cell transfusion which is a limited resource with health risks. Most of the blood sent to the laboratory is discarded (up to 90%) suggesting that volumes can be reduced without compromising care.
The goals of this thesis are to (i) summarize the evidence for reducing blood loss for laboratory testing; (ii) discuss cluster randomized trials; (iii) discuss use…

Dhaka City is the capital of Bangladesh and boundary revisions of Dhaka city refers to the changes of Dhaka city administrative boundary or jurisdiction over time. Dhaka is growing very fast in terms of population and area. So, government is redefining city boundaries and also making big units into several parts for better city management. Now, the challenge is to deal with these changes of administrative regions that seem to be helpful to match with census record that comes out every ten to fifteen years. Dhaka city boundary revisions dataset contains data about the name of the administrative unit, type of administrative unit, year of establishment, year of data record, geometry of administrative unit defining the jurisdiction, type of revisions occurred in the administrative units, time of revisions and the number of subdivisions inside an administrative unit. This thesis aims to integrate Dhaka city boundary revision dataset using semantic web technology that preserves information about changes occurred in the Dhaka city boundary over time.

▼ Upper urinary tract stones are a major determinant of pain and is suggested to accelerate disease progression in patients with autosomal dominant polycystic kidney disease (ADPKD). For these reasons, stones should be optimally managed in patients with ADPKD. However, the kidney distortions may make managing stones challenging in patients with ADPKD. Understanding of the epidemiology of upper urinary tract stones and stone intervention and the outcomes of stone interventions is limited. The aim of this thesis is to understand the epidemiology of upper urinary tract stones and stone interventions and consequences of stone management in patients with ADPKD.
To address this knowledge gap, we conducted two systematic reviews to understand the current knowledge on the prevalence and incidence of upper urinary tract stones, and the success and complication rate of the three common stone interventions (shockwave lithotripsy [SWL], ureteroscopy, and percutaneous nephrolithotomy [PCNL]) in patients with ADPKD. We conducted a chart review to validate International Classification of Diseases, 10th revision (ICD-10) codes related to ADPKD. We then conducted two cohort studies using ICES data to determine and compare the rate of stones and rate of stone intervention, and the complication rate of the most common stone intervention (ureteroscopy) in patients with ADPKD to patients without ADPKD with similar baseline health.
Chapter 2 showed that that there is poor consensus on how often patients with ADPKD develop or undergo intervention for upper urinary tract stones.
Chapter 3 showed that the efficacy and safety of stone interventions in patients with ADPKD remains uncertain.
Chapter 4 summarized the limitations of the existing literature based on the findings of the two systematic reviews.
Chapter 5 showed that majority of the patients with ICD-10 codes related to ADPKD truly have ADPKD according to strict clinical criteria.
Chapter 6 showed that patients with ADPKD presented to the hospital with upper urinary tract stones more, and that urologist were not managing stones in patients with ADPKD in a similar manner to comparable patients without ADPKD. It also showed that ureteroscopy is the most commonly performed stone intervention.
Chapter 7 showed ADPKD is associated with a statistically significant increase emergency department visits in selected patients with ADPKD who received ureteroscopy for upper urinary tract stones compared to patients without ADPKD.
Results can inform the use of ICD-10 codes to build ADPKD cohorts, inform clinical practice guidelines, and guide prognostication.

▼ Despite high interest in examining hospital readmissions, few studies have focused on readmissions among individuals experiencing homelessness, a population with complex health challenges. A cohort of 1,165 homeless adults recruited from homeless shelters and meal programs in Toronto were observed from December 6th, 2004 to March 31st, 2009 using administrative health care databases. Multivariate analyses were used to i) compare the 30-day readmission rate between the homeless participants and a cohort of low-income controls; ii) to compare the readmission rate between hospitalized homeless participants and hospitalized low-income controls, matched on age, sex and case mix group; and iii) to determine risk factors associated with readmission among the homeless participants.Homeless participants were substantially more likely to be readmitted within 30-days as compared to low-income controls, even after accounting for the primary reason for admission. Further research is needed to assess practices and interventions to reduce readmissions in this patient population.

▼ Introduction: Diagnostic validation studies are used to assess the accuracy of
administrative health
data by testing case definitions. Many researchers use descriptive analyses to recommend a case definition.
Purpose: The purpose was to develop and assess model-based methods to select a case definition for identifying individuals with a chronic disease in
administrative health
data.
Methods: A simulation study was used to compare the performance of univariate and bivariate models applied to diagnostic validity measures. The models were demonstrated using analysis of 148 case definitions from a rheumatoid arthritis (RA) validation study.
Results: All models performed well based on bias and mean squared error; however, the bivariate model had poor confidence interval coverage. The RA characteristics that showed association with sensitivity or specificity were number of physician diagnoses, observation time, number of specialist diagnoses, and number of prescriptions.
Conclusion: These models provide researchers with an inferential method for recommending case definitions.

▼ Objective: Although many children are placed in care of child protection services each year, very little is known about how having a child placed in care affects the health and well-being of biological mothers. This study aims to address this gap in knowledge.
Methods: The linkable
administrative data housed at the Manitoba Centre for Health Policy were used to create several cohorts of mothers whose children were born in Manitoba, Canada, identified through child protection case files. Maternal health and social outcomes in the years before and after having a child taken into care were compared using generalized estimating equations. Poisson regression models were used to obtain relative rates of mental health-related outcomes for mothers whose children were taken into care and mothers whose children died. Incidence rate ratios of suicide attempts and completions were obtained using fixed-effects Poisson regression models. Finally, Cox proportional hazard regression models determined rates of avoidable and unavoidable mortality among mothers whose children were taken into care.
Results: Compared with mothers whose children were not placed in care, mothers whose children were taken into care have significantly higher rates of anxiety, substance use, physician visits, hospitalizations, prescriptions, and income assistance use in the years before their children were taken into care; rates increased significantly in the years after. These mothers also had significantly higher rates of depression, anxiety, substance use, physician visits for mental illness, hospitalizations for mental illness, and psychotropic medication use in the years after custody loss compared with mothers who experienced the death of a child. Rates of suicide attempts, death by suicide, avoidable mortality and unavoidable mortality were also higher among mothers whose child was taken into care.
Conclusion: Mothers whose children are taken into care often face many challenges in the years leading up to custody loss; the loss of custody often creates new challenges or exacerbates existing challenges. To address these outcomes, more preventative services should be implemented to keep families together and more supports should be in place to ensure timely family reunification. Meaningful supports need to be provided for mothers who are not reunified with their children.

▼ Background: Identifying maternal risk factors associated with giving birth to children with Fetal Alcohol Spectrum Disorder (FASD) is integral to the development of effective prevention strategies, however, there are no Canadian
data in this area. The objective of this dissertation was to utilize population-based linked
data to generate a large, representative sample of mothers whose children were diagnosed with FASD to investigate: (1) maternal risk factors associated with giving birth to children with FASD; (2) maternal physical and health outcomes; and (3) maternal usage of health services of the study population.
Methods: A cohort of mother-infant dyads from a population of all children born in Manitoba between April 1, 1984 and March 31, 2012 who had an FASD diagnosis from the Manitoba FASD Centre from April 1, 1999 to March 31 2012, with follow-up until December 1, 2013 (study group: n=702). A control group (n=2097) matched 1:3 on date of birth of index child, region of residence, and socioeconomic status was generated to compare exposures and outcomes. Logistic regression analyses were run to determine maternal risk factors for giving birth to children with FASD, and adjusted relative rates for all mental and physical health outcomes, as well as rate of prenatal care, were calculated using generalized estimating equations with a Poisson or Negative Binomial distribution.
Results: The following maternal characteristics were identified as having a statistically significant association with giving birth to children with FASD: history of teen pregnancy, being a single mother at birth of the index child, higher gravidity and parity, having a psychiatric disorder and/or physical health disorder up to three years before the birth of the child, and having inadequate prenatal care. Women who gave birth to children with FASD were also more likely to
ii
be involved with the child welfare system and the justice system, and to take antidepressants during pregnancy. Study group women had higher adjusted rates of substance use disorder, personality disorder, and mood and anxiety disorders before pregnancy, as well as higher adjusted rates of maternal psychological distress during pregnancy and postpartum, and antidepressant prescriptions before, during, and after pregnancy. Adjusted rates were higher among the study group for suicide completion, number of women attempting suicide, and number of attempts after the birth of the child until the end of the study period, as well as for inadequate and low prenatal care.
Conclusion: Women giving birth to children with FASD face significant social complexity, as well as a high psychiatric burden, increased risk of suicide, and are at risk for inadequate prenatal care. FASD prevention strategies are needed that address these maternal risk factors to help reduce the incidence of FASD.

▼ Healthcare utilizations are typically measured independently of each other; neglecting the interdependencies between services. An episode of care is suitable for measuring healthcare utilizations of patients with complex health conditions because it tracks all contacts throughout the healthcare system. The overall goal of this research was to construct an episode of care
data system to study healthcare utilizations and costs of chronic obstructive pulmonary disease (COPD) exacerbations. To achieve this goal, four related studies were undertaken.
The first study (Chapter 2) evaluated the agreement between emergency department (ED)
data and hospital records for capturing transitions between the two care settings. Using the κ statistic as a measure of concordance, we found good agreement between the two
data sources for intra-facility transfers; but only fair agreement for inter-facility transfers. The results show that linking multiple
data sources would be important to identify all related healthcare utilization across care settings.
The second study (Chapter 3) linked hospital
data, ED
data, physician billing claims, and outpatient drug records to construct an episode of care
data system for COPD patients. Latent class analysis was used to identify COPD patient groups with distinct healthcare pathways. Pathways were associated with outcomes such as mortality and costs. A few individuals followed complex pathways and incurred high costs.
Building on the previous study, the next one (Chapter 4) predicted whether high-cost patients in one episode also incurred high costs in subsequent episodes. Using logistic regression models, we found that patient information routinely collected in
administrative health
data could satisfactorily predict those who become persistent high users.
The final study (Chapter 5) used a cross-validation approach to compare the performance of eight alternative linear regression models for predicting costs of episodes of COPD exacerbations. The results indicate that the robust regression model, a model not often considered for cost prediction, was among the best models for predicting episode-based costs.
Overall, this research demonstrated how population-based
administrative health databases could be linked to construct an episode of care
data system for a chronic health condition. The resulting
data system supported novel investigations of healthcare system-wide utilizations and costs.

▼ Despite the breadth of the identified impacts and costs of child maltreatment, a primary challenge in our understanding of child maltreatment is that we still do not have solid numbers of children who experience it. Further, despite child protection systems (CPS) being reliant on mandated reporters to bring concerns of child maltreatment to their attention, there is little information about how systems respond to concerns of child maltreatment. Informed by the public health approach and ecological systems theory, this dissertation utilizes a novel linked
administrative dataset of birth, hospital discharge, and CPS records to provide new knowledge about hospitalizations related to child maltreatment. It does so in three ways: identifying the incidence and prevalence of child maltreatment-related hospitalizations, the risk and protective factors of these hospitalizations, and the systems responses to these hospitalizations, as measured by CPS reports and removals by CPS. Results indicate that most common form of child maltreatment-related hospitalizations was neglect and, more specifically, supervisory neglect. Identified risk factors included child’s low birth weight, mothers who were teenagers at the time of birth, non-first born children, maternal residence in zip codes with high concentrated disadvantage, and a prior CPS report. System responses were dependent on the subtype of maltreatment and type of diagnostic code used. Specifically, physical abuse and codes specifically related to maltreatment had higher rates of CPS reports and removals compared to the other maltreatment subtypes and diagnostic codes not specifically related to maltreatment. These results provide new knowledge regarding child maltreatment. The results can be used to target prevention programming, which are identifiable at birth, increasing their utility. The new knowledge identified through this study has important implications for our understanding of child maltreatment, how we can prevent it, and how current systems are responding to it.

▼ Treating mental illness in primary care improves access to care, but it is unclear how to encourage family physicians to provide adequate mental health services. One approach may be changing how they are remunerated. The objectives of this thesis were to: 1) review the literature on the association between physician remuneration and provision of mental health services, and 2) assess the impact of blended capitation, compared to blended fee-for-service (FFS), on mental health services provision in Ontario. The review found that capitation appears to be associated with fewer services compared to FFS; however, studies of ED visits for mental health reasons were limited. The impact of remuneration models of Ontario physicians was assessed using longitudinal administrative data from ICES and analyzed using fixed-effects linear regression models. Blended capitation was associated with fewer mental health services provided and a slight decrease in the number of ED visits for mental health reasons.

▼ This matched case-control study examined the association between environmental heat exposure and hospital encounters with acute kidney injury (AKI) among adults, 66 years and older, in the province of Ontario, Canada. We matched 52,913 cases who had an AKI event during the warm seasons (April to September) of 2005 to 2012 with 174,222 controls who did not have an AKI event. We matched cases to controls on date, age, sex, residential status, income, and history of chronic kidney disease using a variable one to four matching ratio. We classified heat periods as three consecutive days where the 95th percentile of area-specific daily maximum temperature was reached or exceeded. We determined associations using conditional logistic regression. Compared to non-heat periods, high heat periods were significantly associated with greater risk of AKI (adjusted odds ratio 1.11, 95% confidence interval 1.00 to 1.23).
