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.
