Hospital discharges for substance-related injuries before and during the COVID-19 pandemic: a descriptive surveillance study using administrative data.

ABSTRACT:

Background

The COVID-19 pandemic and associated behavioural changes have contributed to an increase in substance-related hospital discharges, and has altered the injury epidemiology landscape in Canada. We sought to evaluate hospital discharges for substance-related injuries during the pandemic compared with prepandemic and to identify subpopulations that have been greatly affected by substance-related injuries during the first year of the pandemic.

Methods

We compared data on hospital discharges in Canada from before the pandemic (March 2019-February 2020) with discharges during the first year of the pandemic (March 2020-February 2021) using the Discharge Abstract Database. We identified discharges for substance-related injuries using codes from the International Statistical Classification of Diseases and Related Health Problems, 10th Revision. We calculated percent changes, age-standardized rates and age-specific rates of discharges for substance-related injuries.

Results

Hospital discharges for substance-related injuries increased by 7.1% during the first year of the pandemic. Discharges for intentional injuries decreased by 6.3%, whereas unintentional substance-related injuries increased by 15.1% during this period. Male patients accounted for 95.6% of the increase in hospital discharges for substance-related injuries during the first year of the pandemic. We observed a percent increase among discharges for injuries related to alcohol, opioid, cannabinoid, hallucinogen, tobacco, volatile solvents, other psychoactive substances and polysubstance use.

Interpretation

We observed an increase in hospital discharges for substance-related injuries during the first year of the COVID-19 pandemic, compared with the same time period before the pandemic. This work will provide useful insight into the ongoing management of the COVID-19 pandemic, as well as future policy and health care planning related to substance use in Canada.
