Social Determinants Of Health And Uptake Of Colorectal Cancer Screening In Canada, Seth F. Kadish

Electronic Thesis and Dissertation Repository

Colorectal cancer (CRC) screening uptake may be associated with social determinants of health and could indicate potential barriers to health service access. The goal of this thesis was to evaluate the association of social determinants with CRC screening in screen-eligible adults. We used Andersen’s Behavioural Model of Health Service Utilization and the PROGRESS-Plus Framework to conceptualize potential social determinants. Our first study was a systematic review of peer-reviewed Canadian studies, and the second was a cross-sectional analysis of data from the Canadian Longitudinal Study on Aging (CLSA). The systematic review found lower uptake was associated with non-White ethno-racial identity, less …

Functional Neuroimaging Techniques To Examine Falls And Cognition In Older Adults: A Systematic Review, Tia M. Seleem, Raphael Gabiazon

Undergraduate Student Research Internships Conference

Falls in older adults have been attributed to impaired cognition. There is potential for neuroimaging techniques to understand the biological components that are involved in the cognitive processes pertaining to falls. Therefore, the purpose of this systematic review was to analyze how functional neuroimaging can be used to examine the relationship between falls and cognition among older adults. The following five electronic databases were selected to identify peer-reviewed articles in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: 1) Medline (via OVID), 2) PsycINFO (via OVID), 3) CINAHL (via EBSCO), 4) EMBASE (via OVID), and 5) Pubmed. …

Association Between Air Pollution And Incidence Of Dementia: A Systematic Review And Meta-Analysis Of Cohort Studies, Ehsan Abolhasani

Electronic Thesis and Dissertation Repository

Objective. To estimate the risk of dementia in association with exposure to air pollutants.

Methods. Six databases were searched. Cohort studies that reported the hazard ratio (HR) of dementia in association with exposure to air pollutants in adults > 40y were included. For all meta-analyses, the random-effects model was used.

Results. A total of 16 and 13 studies were included in the systematic review and the meta-analysis, respectively. Risk of dementia increased by 4% per 1μg/m³ increase in fine particulate matter level (HR, 1.04; 95%CI, [1.02, 1.06]), which was statistically significant. The risk of dementia increased by 3% per 10μg/m …

The Risk Of Physical Multimorbidity In People With Psychotic Disorders: A Systematic Review And Meta-Analysis, Myanca Rodrigues, Joshua C. Wiener, Saverio Stranges, Bridget L. Ryan, Kelly K. Anderson

Epidemiology and Biostatistics Publications

Background: The occurrence of multiple co-occurring chronic health conditions, known as multimorbidity, is associated with decreases in quality of life for patients and poses unique challenges for healthcare systems. Since people with psychotic disorders have an excess of physical health conditions compared to the general population, they may also be at a higher risk for multimorbidity. We conducted a systematic review and meta-analysis to quantify the prevalence and excess risk of multimorbidity among people with psychotic disorders, relative to those without psychosis.

Methods: We searched the MEDLINE, EMBASE, and PsycINFO databases, and conducted forward and backward citation tracing of included …

Correlates Of Preventable Emergency Department Visits In Canada: Evidence From The Literature And The Canadian Community Health Survey, Tammy Lau

Electronic Thesis and Dissertation Repository

Emergency department (ED) visits for primary healthcare-treatable conditions are preventable and indicate barriers to primary healthcare. The goal of this thesis was to explore the prevalence and key correlates of preventable ED visits among adults in Canada. Our systematic review found that the prevalence of these visits ranged from 4.3% to 59.1% and were associated with younger age, low education, low income, rural residence, and worse self-rated health. Our analysis of data from the 2015-2016 Canadian Community Health Survey found that 39.9% of adults with a regular healthcare provider considered their last ED visit to be preventable. In addition to …

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 …

Improving The Use Of Electronic Medical Records In Primary Health Care: A Systematic Review And Meta-Analysis, Noura Hamade

Electronic Thesis and Dissertation Repository

Electronic Medical Records were first introduced in the 1970s to organize patient information, improve coordination of care, and improve communication. The purpose of this systematic review was to identify interventions aimed at improving EMR use in primary health care settings. Of 2,098 identified studies twelve were included in the review. Results showed that interventions focused on the use of EMR functions were five times more likely to show improvements in EMR use compared to controls. Interventions focused on data quality were five and a half times more likely to show improvements in EMR use compared to controls. Individuals in primary …

Patency And Complication Rates Of The Arteriovenous Fistula: A Systematic Review, Ahmed A. Al-Jaishi

Electronic Thesis and Dissertation Repository

Advantages of fistulas, which include long patency and low complication rates, were ascertained over two decades ago and may not apply to the contemporary dialysis population. We conducted a systematic review to summarize the patency and complication rates of fistulas from literature published after 1999. We screened 7,008 citations and 62 articles met our criteria. The risk of primary failure was 27% (95% confidence interval (CI): 23–32%). When primary failures were included, the primary and secondary patency rates were 59% (CI 53–64%) and 66% (CI 58–74%) at one year, respectively. The median rates of infection, ischemic steal syndrome, and thrombosis …

Shift Work And Cardiovascular Events: Systematic Review And Meta-Analysis, Manav V. Vyas

Electronic Thesis and Dissertation Repository

The prevalence of shift work is increasing in the general population. There is conflicting epidemiologic evidence on the association between shift work and cardiovascular disease. We performed a systematic review and meta-analysis of observational studies that measured shift work-cardiovascular disease associations. We screened 12,350 articles and identified 35 eligible studies. The pooled risk ratios (RR) for myocardial infarction, all coronary events and ischemic stroke were 1.23 (95% confidence interval [CI] 1.15 to 1.31, I² = 0), 1.24 (95% CI 1.10 to 1.39, I² = 85%) and 1.05 (95% CI 1.01 to 1.09, I² = 0), respectively. The …
