Hospital utilization by older and younger patients in Canada: pre-pandemic findings.

Many countries are experiencing a post-pandemic surge in hospital utilization along with accelerating population aging. Maximal hospital efficiency is required, with utilization evidence essential for identifying appropriate hospital or broader health system reforms. We offer an investigation of the most recent pre-COVID year (2019-2020) of complete population-based hospital utilization data to describe and compare the use of hospitals by older (65+) and younger (0-64) people admitted for inpatient services in Canada. We found that 35.7% of all 1,888,133 admitted individuals and 39.8% of all 2,543,227 hospital episodes involved people aged 65+, representing 4,963,766 or 17.1% of the study population. This study, as do previous Canadian and other ones, found hospitals admit more younger people than older people. The admission and care patterns of both younger and older patients reveal a need for more community-based services to shorten older patient hospitalizations and prevent avoidable hospitalizations by both younger and older people.
