Changes in emergency department use in British Columbia, Canada, during the first 3 years of the COVID-19 pandemic.

Background: Previous studies have shown reductions in the volume of emergency department visits early in the COVID-19 pandemic, but few have evaluated the pandemic's impact over time or stratified analyses by reason for visits. We aimed to quantify such changes in British Columbia, Canada, cumulatively and during prominent nadirs, and by reason for visit, age and acuity.

Methods: We included data from the National Ambulatory Care Reporting System for 30 emergency departments across BC from January 2016 to December 2022.

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.

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].
