Background Involuntary admissions to psychiatric hospitals are common; however, research examining the trends in prevalence over time and predictors is limited. Aims To examine risk factors for involuntary Ontario, Canada. Method We conducted an analysis of all mental health bed from 2009 2013 assessed association between patient sociodemographics, service utilisation, pathway care severity characteristics using a modified Poisson regression.

Articulating future risk of diabetes at the population level can inform prevention strategies. While previous studies have characterized burden according to socioeconomic status (SES), none studied risk. We quantified influence multiple constructs SES on using Diabetes Population Risk Tool (DPoRT), a validated prediction algorithm that generates 10-year rates new cases. applied DPoRT adults aged 30–64 in 2011–2012 Canadian Community Health Survey (n = 65,372) and calculated for 2021–22. A...

Abstract Aims Ethnic minority groups often have more complex and aversive pathways to mental health care. However, large population-based studies are lacking, particularly regarding involuntary hospitalisation. We sought examine the risk of admission among first-generation ethnic with early psychosis in Ontario, Canada. Methods Using administrative data, we constructed a retrospective cohort (2009–2013) people first-onset non-affective psychotic disorder aged 16–35 years. This was linked...

Introduction Recent publications have called for substantial improvements in the design, conduct, analysis and reporting of prediction models. Publication study protocols, with prespecification key aspects plan, can help to improve transparency, increase quality protect against increased type I error. Valid population-based risk algorithms are essential population health planning policy decision-making. The purpose this is develop, evaluate apply cardiovascular disease (CVD) setting. Methods...

Objective: To estimate the rates of suicide and self-harm among recent immigrants to determine which immigrant-specific risk factors are associated with these outcomes. Methods: Population-based cohort study using linked health administrative data sets (2003 2017) in Ontario, Canada included adults ≥18 years, living Ontario ( N = 9,055,079). The main exposure was immigrant status (long-term resident vs. immigrant). Immigrant-specific exposures visa class country origin. Outcome measures were...

Objective: Small clinical samples suggest that psychiatric inpatients report a lifetime history of interpersonal trauma. Since past experiences trauma may complicate prognosis and treatment trajectories, population-level knowledge is needed about its prevalence correlates among inpatients.
