Primary care physicians play a central role in pathways to care for first-episode psychosis, and their increased involvement in early detection could improve service-related outcomes. The aim of this study was to estimate the proportion of psychosis first diagnosed in primary care, and identify associated patient and physician factors. We used linked health administrative data to construct a retrospective cohort of people aged 14-35 years with a first diagnosis of non-affective psychosis in Ontario, Canada between 2005-2015. We restricted the sample to patients with help-seeking contacts for mental health reasons in primary care in the six months prior to first …


Rapid Rhino Vs. Merocel: A Retrospective Analysis Of Patients With Anterior Epistaxis Visiting Emergency Rooms In London, Ontario, Dhatri Shukla Dec 2022

Rapid Rhino Vs. Merocel: A Retrospective Analysis Of Patients With Anterior Epistaxis Visiting Emergency Rooms In London, Ontario, Dhatri Shukla

Electronic Thesis and Dissertation Repository

When patients present to an emergency room (ER) with a nosebleed, one technique that physicians employ is the application of nasal packing. Merocel is a common nasal pack utilized in ER because of their low cost. Rapid Rhino is a nasal packing that is more comfortable for patients but is more costly than Merocel. Costing for epistaxis treatment is more than initial treatment costs and needs to consider rebleed rates. Using a retrospective cohort study design with covariates adjusted by propensity scores, we compared the costs associated with Merocel, and Rapid Rhino from the hospital and provincial healthcare perspectives. Merocel …

Association Of Pediatric Buccal Epigenetic Age Acceleration With Adverse Neonatal Brain Growth And Neurodevelopmental Outcomes Among Children Born Very Preterm With A Neonatal Infection., Noha Gomaa, Chaini Konwar, Nicole Gladish, Stephanie H Au-Young, Ting Guo, Min Sheng, Sarah M Merrill, Edmond Kelly, Vann Chau, Helen M Branson, Linh G Ly, Emma G Duerden, Ruth E Grunau, Michael S Kobor, Steven P Miller

Department of Medicine Publications

IMPORTANCE: Very preterm neonates (24-32 weeks' gestation) remain at a higher risk of morbidity and neurodevelopmental adversity throughout their lifespan. Because the extent of prematurity alone does not fully explain the risk of adverse neonatal brain growth or neurodevelopmental outcomes, there is a need for neonatal biomarkers to help estimate these risks in this population.

OBJECTIVES: To characterize the pediatric buccal epigenetic (PedBE) clock-a recently developed tool to measure biological aging-among very preterm neonates and to assess its association with the extent of prematurity, neonatal comorbidities, neonatal brain growth, and neurodevelopmental outcomes at 18 months of age.

DESIGN, SETTING, AND …

A Framework To Support The Progressive Implementation Of Integrated Team-Based Care For The Management Of Copd: A Collective Case Study., Shannon L. Sibbald, Vaidehi Misra, Madelyn Dasilva, Christopher Licskai

Health Studies Publications

BACKGROUND: In Canada, there is widespread agreement about the need for integrated models of team-based care. However, there is less agreement on how to support the scale-up and spread of successful models, and there is limited empirical evidence to support this process in chronic disease management. We studied the supporting and mitigating factors required to successfully implement and scale-up an integrated model of team-based care in primary care.

METHODS: We conducted a collective case study using multiple methods of data collection including interviews, document analysis, living documents, and a focus group. Our study explored a team-based model of care for …

Health Studies Publications

INTRODUCTION: Health systems are a complex web of interacting and interconnected parts; introducing an intervention, or the allocation of resources, in one sector can have effects across other sectors and impact the entire system. A prerequisite for effective health system reorganisation or transformation is a broad and common understanding of the current system amongst stakeholders and innovators. Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are common chronic diseases with high health care costs that require an integrated health system to effectively treat.

STUDY DESCRIPTION: This case study documents the first phase of system transformation at a regional level …


Mental Health Services Provision In Primary Care And Emergency Department Settings: Analysis Of Blended Fee-For-Service And Blended Capitation Models In Ontario, Canada., Thyna Vu, Kelly K Anderson, Nibene H Somé, Amardeep Thind, Sisira Sarma Jul 2021

Mental Health Services Provision In Primary Care And Emergency Department Settings: Analysis Of Blended Fee-For-Service And Blended Capitation Models In Ontario, Canada., Thyna Vu, Kelly K Anderson, Nibene H Somé, Amardeep Thind, Sisira Sarma

Epidemiology and Biostatistics Publications

Treating mental illnesses in primary care is increasingly emphasized to improve access to mental health services. Although family physicians (FPs) or general practitioners are in an ideal position to provide the bulk of mental health care, it is unclear how best to remunerate FPs for the adequate provision of mental health services. We examined the quantity of mental health services provided in Ontario's blended fee-for-service and blended capitation models. We evaluated the impact of FPs switching from blended fee-for-service to blended capitation on the provision of mental health services in primary care and emergency department using longitudinal health administrative data …

Quality Of Diabetes Care In Blended Fee-For-Service And Blended Capitation Payment Systems., Mary Aderayo Bamimore, Rose Anne Devlin, Gregory S Zaric, Amit X Garg, Sisira Sarma

Epidemiology and Biostatistics Publications

OBJECTIVES: In the middle to late 2000s, many family physicians switched from a Family Health Group (FHG; a blended fee-for-service model) to a Family Health Organization (FHO; a blended capitation model) in Ontario, Canada. The evidence on the link between physician remuneration schemes and quality of diabetes care is mixed in the literature. We examined whether physicians who switched from the FHG to FHO model provided better care for individuals living with diabetes relative to those who remained in the FHG model.

METHODS: Using longitudinal health administrative data from 2006 to 2016, we investigated the impact of physicians switching from …

Physician Remuneration Schemes, Psychiatric Hospitalizations And Follow-Up Care: Evidence From Blended Fee-For-Service And Capitation Models., Thyna Vu, Kelly K Anderson, Rose Anne Devlin, Nibene H Somé, Sisira Sarma

Epidemiology and Biostatistics Publications

Psychiatric hospitalizations could be reduced if mental illnesses were detected and treated earlier in the primary care setting, leading to the World Health Organization recommendation that mental health services be integrated into primary care. The mental health services provided in primary care settings may vary based on how physicians are incentivized. Little is known about the link between physician remuneration and psychiatric hospitalizations. We contribute to this literature by studying the relationship between physician remuneration and psychiatric hospitalizations in Canada's most populous province, Ontario. Specifically, we study family physicians (FPs) who switched from blended fee-for-service (FFS) to blended capitation remuneration …

Analysis Of Billings Data To Evaluate Patterns Of Mental Health Services In Primary Care And Emergency Departments By Blended Fee-For-Service And Blended Capitation Models In Ontario, Canada, Thy H. Vu Feb 2020

Analysis Of Billings Data To Evaluate Patterns Of Mental Health Services In Primary Care And Emergency Departments By Blended Fee-For-Service And Blended Capitation Models In Ontario, Canada, Thy H. Vu

Electronic Thesis and Dissertation Repository

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 …

Production Of Physician Services Under Fee-For-Service And Blended Fee-For-Service: Evidence From Ontario, Canada., Nibene H Somé, Rose Anne Devlin, Nirav Mehta, Greg Zaric, Lihua Li, Salimah Shariff, Bachir Belhadji, Amardeep Thind, Amit Garg, Sisira Sarma

Epidemiology and Biostatistics Publications

We examine family physicians' responses to financial incentives for medical services in Ontario, Canada. We use administrative data covering 2003-2008, a period during which family physicians could choose between the traditional fee for service (FFS) and blended FFS known as the Family Health Group (FHG) model. Under FHG, FFS physicians are incentivized to provide comprehensive care and after-hours services. A two-stage estimation strategy teases out the impact of switching from FFS to FHG on service production. We account for the selection into FHG using a propensity score matching model, and then we use panel-data regression models to account for observed …

Objectives: To determine if levels of neighbourhood poverty and neighbourhood antisocial behaviour modify associations between household poverty and child and youth mental health problems. Methods: Data come from the 2014 Ontario Child Health Study—a provincially representative survey of 6537 families with 10,802 four- to 17-year-olds. Multivariate multilevel modelling was used to test if neighbourhood poverty and antisocial behaviour interact with household poverty to modify associations with children’s externalizing and internalizing problems based on parent assessments of children (4- to 17-year-olds) and self-assessments of youth (12- to 17-year-olds). Results: Based on parent assessments, neighbourhood poverty, and antisocial behaviour modified associations between …


Family Physician Remuneration Schemes And Specialist Referrals: Quasi-Experimental Evidence From Ontario, Canada., Sisira Sarma, Nirav Mehta, Rose Anne Devlin, Koffi Ahoto Kpelitse, Lihua Li Oct 2018

Family Physician Remuneration Schemes And Specialist Referrals: Quasi-Experimental Evidence From Ontario, Canada., Sisira Sarma, Nirav Mehta, Rose Anne Devlin, Koffi Ahoto Kpelitse, Lihua Li

Epidemiology and Biostatistics Publications

Understanding how family physicians respond to incentives from remuneration schemes is a central theme in the literature. One understudied aspect is referrals to specialists. Although the theoretical literature has suggested that capitation increases referrals to specialists, the empirical evidence is mixed. We push forward the empirical research on this question by studying family physicians who switched from blended fee-for-service to blended capitation in Ontario, Canada. Using several health administrative databases from 2005 to 2013, we rely on inverse probability weighting with fixed-effects regression models to account for observed and unobserved differences between the switchers and nonswitchers. Switching from blended fee-for-service …

Higher And Lower Order Factor Analyses Of The Temperament In Middle Childhood Questionnaire., Yuliya Kotelnikova, Thomas M Olino, Daniel N Klein, Sarah V M Mackrell, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

The Temperament in Middle Childhood Questionnaire (TMCQ) is a widely used parent-report measure of temperament. However, neither its lower nor higher order structures has been tested via a bottom-up, empirically based approach. We conducted higher and lower order exploratory factor analyses (EFAs) of the TMCQ in a large ( N = 654) sample of 9-year-olds. Item-level EFAs identified 92 items as suitable (i.e., with loadings ≥.40) for constructing lower order factors, only half of which resembled a TMCQ scale posited by the measure's authors. Higher order EFAs of the lower order factors showed that a three-factor structure (Impulsivity/Negative Affectivity, Negative …
