Social Determinants Of Access To Primary Care In Canada, Feben W. Alemu

Electronic Thesis and Dissertation Repository

Despite the promise of universal care, many Canadians report having unmet healthcare needs. We conducted two studies: (1) a systematic review of studies on social determinants of health (SDH) and unmet need; and (2) a secondary analysis using the Canadian Longitudinal Study on Aging (CLSA) to investigate the association of SDH and (2a) self-reported unmet need and (2b) having a family physician. The review (n=40) found a positive association between unmet need and lower income, mental health and chronic conditions, and negative association with older age, better perceived health and having a family physician. The CLSA analysis found the odds …

Sex Differences In The Clinical Presentation Of Early Psychosis In A Primary Care Setting, Brooke Carter

Electronic Thesis and Dissertation Repository

Psychotic disorders can be variable in clinical presentation, and there may be differences by sex. The objective of this thesis was to explore sex differences in the clinical presentation of early psychosis in the context of primary care. Our systematic review and meta-analysis found that men experienced more negative symptoms and had a higher prevalence of substance use issues, whereas women experienced more depressive symptoms and had higher functioning. Our electronic medical record analysis from primary care found that positive symptoms and substance use were less prevalent in the medical records of women. We also found that visits by women …

Chronic Disease Management In A Nurse Practitioner Led Clinic: An Interpretive Description Study, Natalie Floriancic

Electronic Thesis and Dissertation Repository

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 …

Off-Label Use Of Second Generation Antipsychotics In Primary Care -An Exploratory Study, Nima Gheisarzadeh

Electronic Thesis and Dissertation Repository

Over the past two decades, the use of antipsychotics has increased tremendously worldwide, and second-generation antipsychotics (SGAs) have been the main driver of this trend. The extensive use of SGAs for off-label purposes has raised concerns over their role in clinical practice. In particular, studies have revealed serious metabolic and cardiovascular effects, and evidence is lacking on SGAs’ effectiveness. Despite the concerns, the extent and pattern of SGAs’ off-label use is largely unknown within the context of the Canadian primary health care system. Using electronic medical record (EMR) data from 14 practices in southwestern Ontario, we investigated the number of …

Identifying Service Utilization Patterns In Primary Care By Young People With First-Episode Psychosis, Nicole Schoer

Electronic Thesis and Dissertation Repository

Minimizing the duration of untreated psychosis in the first few years after illness onset is essential for improving prognosis for people with psychotic disorders. Leading up to the first onset of psychosis, many people experience early signs and symptoms, suggesting that there may be help-seeking or service utilization prior to first diagnosis. The family physician has been found to play a pivotal role in the pathways to care for people with first-episode psychosis. In this study, we used health administrative data from Ontario to construct a population-based retrospective cohort. These data were used to explore whether people with psychotic disorders …

The Impact Of The Diabetes Management Incentive On Diabetes-Related Services, Hospitalizations, And Mortality Risk In Ontario, Thaksha Thavam

Electronic Thesis and Dissertation Repository

Effective diabetes management provided in primary care has the potential to reduce hospitalizations and mortality. To improve diabetes management, a Diabetes Management Incentive (DMI) was introduced by the Ontario government for family physicians practicing in patient enrolment models. This thesis has three main objectives: 1) review the literature on the association between financial incentives for diabetes care and diabetes-related hospitalizations and mortality; 2) and 3) examine the impact of DMI on: diabetes-related services, diabetes-related hospitalizations, diabetes-related hospitalization costs, and mortality risk in Ontario. A review of the literature on the incentives revealed inconsistent findings. The impact of DMI was assessed …

Exploring Quality Improvement For Diabetes Care: A Multiple Case Study Of Primary Care Teams In First Nations Communities In Canada, Meghan Fournie

This study provides insight into how clinical QI teams drew upon multiple sources of knowledge and information to inform their QI activities, the importance …

Chronic Disease Risk Prediction Models And Their Impacts On Behavioural And Health Outcomes: A Systematic Review And Meta-Analysis, Patrick Kim

Electronic Thesis and Dissertation Repository

Risk prediction models are tools that predict an individual’s risk of developing a health outcome. They were developed to influence patient management by guiding preventive interventions, with the goal of reducing the incidence of new diseases. Studies examining their impacts are uncommon, and no consensus regarding their effects has been reached. This systematic review sought to determine the impact of risk prediction models for chronic diseases on physician behaviour, patient behaviour, and patient health outcomes. Twenty-two studies were found to be eligible for review. The results demonstrated that: 1) physician behaviour may be positively influenced, though a statistically significant result …

Patient-Centered Primary Care Of Adults With Severe Or Profound Developmental Disabilities: The Patient–Physician Relationship, Katherine C. Stringer

Electronic Thesis and Dissertation Repository

Adults with developmental disabilities receive most of their health care from family physicians, yet little is known of the development of the patient-physician relationship in this population. This qualitative study used a grounded theory approach to describe the development of this relationship between adult patients with severe or profound developmental disabilities and their family physicians. Semi-structured interviews were conducted with 13 caregivers and 15 family physicians of these patients. The recognition of the patient’s vulnerabilities was a common starting point. Caregivers and patients approached the patient-physician relationship as one unit with the person they cared for as part of the …

The Impact Of Financial Incentives For Cervical Cancer Screening In Ontario's Primary Care Delivery Models, Ciara Pendrith

Electronic Thesis and Dissertation Repository

Physicians practicing in capitation-based Family Health Organizations and fee-for-service-based Family Health Groups receive bonuses for delivering preventive care, including cervical cancer screening, while those practicing in the traditional fee-for-service model do not. Financial incentives were introduced to increase Ontario’s cervical screening rate to 85%. To date, the impact of incentives for cervical screening on screening rate and cost-effectiveness have not been assessed. Patient-level data obtained from the Institute for Clinical Evaluative Sciences were used to estimate primary care model screening rates and cancer treatment costs. A microsimulation model was developed from published cervical cancer natural history models and parameterized using …
