Delirium: what is the impact on treatment following stroke and how can we predict it?

Abstract

Background

Delirium is a neglected, yet common, complication of stroke. While there is clear evidence that delirium negatively impacts mortality and morbidity in stroke survivors, it is unknown how it affects participation in Allied Health, which are aimed at regaining and improving functional ability following a stroke.

Objectives/Aims

To undertake a literature review to determine the impact of delirium on participation in allied health interventions. To conduct an external validation of a delirium prediction tool (DPT) in an acute stroke population as developed by Oldenbeuving et al (2014).

Method

Systematic review of the impact of delirium on post-stroke rehabilitation was undertaken. Due to a lack of publications in this population, the search was expanded to include all admission types. The clinical study is an inpatient, cross-sectional observational study currently being conducted at the Ballarat Base Hospital, with Austin Hospital also involved.

Results

The literature review identified two articles that both suggested that delirium negatively impacts participation in allied health interventions. The clinical study has so far only involved a small population of patients and we plan to present preliminary findings.

Implications/Outcomes for Planned Research Project

The Literature review has identified an area of need for further research, to improve our understanding of the interplay between a common complication and a key management aspect following acute stroke. If the prediction tool is found to reliably predict risk of delirium, it could be incorporated into standard stroke care, allowing for interventions to minimise the risk and impact of delirium.

Final Thoughts

We would aim to update on our literature review, as well as our progress with the clinical study which was presented at the BHS Research Week in 2017
