The burden of psychiatric disorders associated with orofacial cleft pathology among children in Ontario, Canada.

Background: Individuals with orofacial cleft (OFC) may be at a higher risk of developing psychiatric disorders (PD) than the general population. We determined the risk of psychiatric diagnoses in children with OFC in Canada.

Methods: This population-based retrospective cohort study used health administrative data from the province of Ontario, Canada.

Meta-analysis of multi-jurisdictional health administrative data from distributed networks approximated individual-level multivariable regression.

Background And Objectives: Compare meta-analysis in a distributed network to individual-level analysis for assessment of time trends of health services utilization with health administrative data.

Methods: We used administrative data from Ontario, Canada to analyze temporal trends in pediatric inflammatory bowel disease health services use. Beta coefficients were obtained using negative binomial, logistic, and Cox proportional hazards regression models.

Cohort study of team-based care among marginalized people who use drugs in Ottawa.

Objective: To describe team-based care use among a cohort of people who use drugs (PWUD) and to determine factors associated with receipt of team-based care.

Design: A cohort study using survey data collected between March and December 2013. These data were then linked to provincial-level health administrative databases to assess patterns of primary care among PWUD in the 2 years before survey completion.

Real world evidence of the association between medication and life expectancy in elderly inflammatory bowel disease: a population-based cohort study.

Background: Life expectancy in people with inflammatory bowel disease (IBD) has increased but remains shorter than in people without IBD. We describe the life expectancy associated with IBD therapies among the growing number of older adults living with IBD.

Methods: Older adults (≥ 65 years) with IBD were identified from population-based health administrative data using a validated algorithm.

Shifting Health Care Use from Hospitalisations and Surgeries to Outpatient Visits in Children with Inflammatory Bowel Disease: A Population-based Cohort Study from Ontario, Canada.

Background: Modern, specialised care for children with inflammatory bowel disease [IBD] may have resulted in changes in health services use. We report trends over time in health services utilisation and surgery for children with IBD and children without IBD.

Methods: Children aged <18 years, diagnosed with IBD between 1994 and 2013 [n = 5518] and followed until 2015 in Ontario, Canada, were identified from health administrative data and matched to children without IBD on age, sex, rural/urban household, and income [n = 26,677].
