Abstract

Background

The occupational therapy (OT) in care homes study (OTCH) aims to investigate the effect of a targeted course of individual OT (with task training, provision of adaptive equipment, minor environmental adaptations and staff education) for stroke survivors living in care homes, compared to usual care.

Methods

A cluster randomised controlled trial of United Kingdom (UK) care homes (n = 90) with residents (n = 900) who have suffered a stroke or transient ischaemic attack (TIA), and who are not receiving end-of-life care. Care homes are randomised to either the intervention group (3 months of OT) or the control group (standard care). The primary outcome measure is independence in self-care activities of daily living (Barthel Activities of Daily Living Index). Secondary outcome measures are mobility (Rivermead Mobility Index), mood (Geriatric Depression Scale), preference based quality of life measured from EQ-5D and costs associated with each intervention groups. Quality adjusted life years (QALYs) will be derived based on the EQ-5D scores. Cost effectiveness analysis will be estimated and measured by incremental cost effectiveness ratio. Measurements are taken at baseline prior to randomisation and at 3, 6 and 12 months post randomisation. Staff training on facilitating independence and mobility and the use of adaptive equipment, will be delivered to every home, with control homes receiving this after the 12 month follow-up. Homes will be stratified by centre and by type of care provided and randomised (50:50) using blocked randomisation within strata to receive either the OT intervention or control (usual care). Allocation will be concealed from the independent assessors, but the treating therapists and residents will be unblinded from the intervention.

Discussion

This study will be the largest cluster randomised control trial of OT in care homes to date and will clarify the currently inconclusive literature on the efficacy of OT for stroke and TIA survivors residing in care homes. Trial registration ISRCTN00757750
