In-Home Rehabilitation Resources and Avoidable Admissions to Inpatient Rehabilitation after Stroke: An Ecological Study

Abstract

Background and purpose:In Ontario (Canada’s most populous province), it has been suggested that mildly impaired stroke patients are being admitted to inpatient rehabilitation unnecessarily due to a lack of alternative options in the community. This ecological study aimed to formally test this hypothesis.Methods:Patients admitted to an inpatient rehabilitation bed in Ontario’s most highly functioning patient classification group (Rehabilitation Patient Group 1160) were retrospectively identified as potentially avoidable admissions, and the proportion of such patients was calculated for each Local Health Integration Network every year between 2006/2007 and 2010/2011. Five indicators of community-based rehabilitation availability were used to test the relationships between avoidable admissions and resource indicators.Results:Of the 25 correlations tested, 21 agreed with the hypothesized direction of effect and 4 reached statistical significance. Logistic-linear regressions on combined data from each of the 5 years demonstrated statistically significant associations between all 5 resource indicators and the proportion of potentially avoidable admissions.Conclusions:This study confirms the suggestion of variation in the proportion of mildly impaired patients admitted to inpatient rehabilitation across Ontario’s Local Health Integration Networks. It also adds evidence to support the concern that a lack of community-based rehabilitation is contributing to these potentially avoidable admissions.
