An Occupational Therapy intervention for residents with stroke-related disabilities in UK Care Homes (OTCH): cluster randomised controlled trial with economic evaluation.

BACKGROUND: Care home residents with stroke-related disabilities have significant activity limitations. Phase II trial results suggested a potential benefit of occupational therapy (OT) in maintaining residents' capacity to engage in functional activity. OBJECTIVE: To evaluate the clinical effectiveness and cost-effectiveness of a targeted course of OT in maintaining functional activity and reducing further health risks from inactivity for UK care home residents living with stroke-related disabilities. DESIGN: Pragmatic, parallel-group, cluster randomised controlled trial with economic evaluation. Cluster randomisation occurred at the care-home level. Homes were stratified according to trial administrative centre and type of care provided (nursing or residential), and they were randomised 1 : 1 to either the intervention or the control arm. SETTING: The setting was 228 care homes which were local to 11 trial administrative centres across England and Wales. PARTICIPANTS: Care home residents with a history of stroke or transient ischaemic attack, including residents with communication and cognitive impairments, not receiving end-of-life care. INTERVENTION: Personalised 3-month course of OT delivered by qualified therapists. Care workers participated in training workshops to support personal activities of daily living. The control condition consisted of usual care for residents. MAIN OUTCOME MEASURES: Outcome data were collected by a blinded assessor. The primary outcome at the participant level was the Barthel Index of Activities of Daily Living (BI) score at 3 months. The secondary outcomes included BI scores at 6 and 12 months post randomisation, and the Rivermead Mobility Index, Geriatric Depression Scale-15 and European Quality of Life-5 Dimensions, three levels, questionnaire scores at all time points. Economic evaluation examined the incremental cost per quality-adjusted life-year (QALY) gain. Costs were estimated from the perspective of the NHS and Personal Social Services. RESULTS: Overall, 568 residents from 114 care homes were allocated to the intervention arm and 474 residents from another 114 care homes were allocated to the control arm, giving a total of 1042 participants. Randomisation occurred between May 2010 and March 2012. The mean age of participants was 82.9 years, and 665 (64%) were female. No adverse events attributable to the intervention were recorded. Of the 1042 participants, 870 (83%) were included in the analysis of the primary outcome (intervention, n = 479; control, n = 391). The primary outcome showed no significant differences between groups. The adjusted mean difference in the BI score between groups was 0.19 points higher in the intervention arm [95% confidence interval (CI) -0.33 to 0.70, p = 0.48; adjusted intracluster correlation coefficient 0.09]. Secondary outcome measures showed no significant differences at all time points. Mean incremental cost of the Occupational Therapy intervention for residents with stroke living in UK Care Homes intervention was £438.78 (95% CI -£3360.89 to £1238.46) and the incremental QALY gain was 0.009 (95% CI -0.030 to 0.048). LIMITATIONS: A large proportion of participants with very severe activity-based limitations and cognitive impairment may have limited capacity to engage in therapy. CONCLUSION: A 3-month individualised course of OT showed no benefit in maintaining functional activity in an older care home population with stroke-related disabilities. FUTURE WORK: There is an urgent need to reduce health-related complications caused by inactivity and to provide an enabling built environment within care homes.

An occupational therapy intervention for residents with stroke related disabilities in UK care homes (OTCH): cluster randomised controlled trial.

OBJECTIVE: To evaluate the clinical efficacy of an established programme of occupational therapy in maintaining functional activity and reducing further health risks from inactivity in care home residents living with stroke sequelae. DESIGN: Pragmatic, parallel group, cluster randomised controlled trial. SETTING: 228 care homes (>10 beds each), both with and without the provision of nursing care, local to 11 trial administrative centres across the United Kingdom. PARTICIPANTS: 1042 care home residents with a history of stroke or transient ischaemic attack, including those with language and cognitive impairments, not receiving end of life care. 114 homes (n=568 residents, 64% from homes providing nursing care) were allocated to the intervention arm and 114 homes (n=474 residents, 65% from homes providing nursing care) to standard care (control arm). Participating care homes were randomised between May 2010 and March 2012. INTERVENTION: Targeted three month programme of occupational therapy, delivered by qualified occupational therapists and assistants, involving patient centred goal setting, education of care home staff, and adaptations to the environment. MAIN OUTCOME MEASURES: Primary outcome at the participant level: scores on the Barthel index of activities of daily living at three months post-randomisation. Secondary outcome measures at the participant level: Barthel index scores at six and 12 months post-randomisation, and scores on the Rivermead mobility index, geriatric depression scale-15, and EuroQol EQ-5D-3L questionnaire, at all time points. RESULTS: 64% of the participants were women and 93% were white, with a mean age of 82.9 years. Baseline characteristics were similar between groups for all measures, personal characteristics, and diagnostic tests. Overall, 2538 occupational therapy visits were made to 498 participants in the intervention arm (mean 5.1 visits per participant). No adverse events attributable to the intervention were recorded. 162 (11%) died before the primary outcome time point, and 313 (30%) died over the 12 months of the trial. The primary outcome measure did not differ significantly between the treatment arms. The adjusted mean difference in Barthel index score at three months was 0.19 points higher in the intervention arm (95% confidence interval -0.33 to 0.70, P=0.48). Secondary outcome measures also showed no significant differences at all time points. CONCLUSIONS: This large phase III study provided no evidence of benefit for the provision of a routine occupational therapy service, including staff training, for care home residents living with stroke related disabilities. The established three month individualised course of occupational therapy targeting stroke related disabilities did not have an impact on measures of functional activity, mobility, mood, or health related quality of life, at all observational time points. Providing and targeting ameliorative care in this clinically complex population requires alternative strategies.Trial registration Current Controlled Trials ISRCTN00757750.
