Identifying mental health and substance use disorders using emergency department and hospital records: a population-based retrospective cohort study of diagnostic concordance and disease attribution.

ABSTRACT:

Objectives

Administrative data are increasingly being used for surveillance and monitoring of mental health and substance use disorders (MHSUD) across Canada. However, the validity of the diagnostic codes specific to MHSUD is unknown in emergency departments (EDs). Our objective was to determine the concordance, and individual-level and hospital-level factors associated with concordance, between diagnosis codes assigned in ED and at discharge from hospital for MHSUD-related conditions.

Design

Population-based retrospective cohort study.

Setting

EDs and hospitals within Vancouver Coastal Health Authority (VCH), British Columbia, Canada.

Participants

16 926 individuals who were admitted into a VCH hospital following an ED visit from 1 April 2009 to 31 March 2017,
