A Cross-Sectional Descriptive Study Using Health Administrative Data to Examine the Characteristics of Older Adults Incurring Delayed Discharge Days for Non-Clinical Reasons During the COVID-19 Pandemic in Alberta, Canada

Abstract

Background

Our study strived to 1) describe the characteristics of older adults incurring delayed discharge days in Alberta from Apr 01, 2019 to March 31, 2022; 2) examine the prevalence and length of delayed discharge days during the COVID-19 pandemic.

Method

We conducted a cross-sectional descriptive study using provincial health administrative data. We included adults ≥65 discharged from hospital from Apr 01, 2019–Mar 31, 2022 in Alberta and whose hospital stay included at least one delayed discharge day. The demographic characteristics of participants were reported in proportions or mean/median. Study period was divided into pandemic waves (pre-pandemic: Apr 1, 2019-Jan 31, 2020; Wave 1: Feb 1, 2020-Aug 31, 2020; Wave 2: Sept 1, 2020-Feb 14, 2021; Wave 3 and beyond: Feb 15, 2021-Mar 31, 2022). Prevalence of delayed discharge in each wave and their median length of stay (IQR) were reported.

Results

From Apr 01, 2019 to Mar 31, 2022, there were 367,912 hospitalizations among older adults living in Alberta. 3.73% (n=13,717) contained at least one delayed discharge day. The percentage of delayed discharge prior to COVID-19 and during each wave stayed consistent. Wave 3 had the shortest median length of stay (29, IQR 15-51). Wave 2 (45.2%) and Wave 3 (45.3%) had higher proportion of patients requiring maximal assistance on the Activities of Daily Living (ADLs). From pre-COVID to Wave 3, there were increases in the proportions of patients discharged to long term care (36.4% in pre-COVID to 40.8% by Wave 3).

Conclusions

Frequency of delayed discharge hospitalizations was consistent across the pandemic waves. Wave 3 had shorter length of delayed discharge hospitalization. The proportion of patients who were discharged to LTC increased over the course of the pandemic.
