Extended occupational therapy showed no significant improvement in behavioral symptoms for dementia patients

This randomized controlled trial investigated the impact of extended occupational therapy on patients with mild-to-moderate dementia. The study population consisted of community-dwelling adults in France. A total of 238 participants were enrolled in the trial. The setting for the intervention involved occupational therapy services. The comparator group received standard occupational therapy consisting of 12 to 15 home-based sessions over a 3 to 4-month period. The intervention group received occupational therapy maintained for an additional 4 months beyond the standard duration.

The primary outcome measured behavioral symptoms using the Neuropsychiatric Inventory at 8 months. The absolute number of participants assessed for the primary outcome was 211. The main results indicated no significant improvement compared to controls. The adjusted mean difference was -3.8. The 95% confidence interval ranged from -10.3 to 2.7. The p-value indicated no statistical significance for the primary outcome.

Key secondary outcomes included functional performance, depressive symptoms, quality of life, institutionalization, caregivers' burden, and sense of competence. The study did not report specific numerical results for these secondary outcomes in the provided data. Safety and tolerability findings were not reported. There were no reported adverse events, serious adverse events, or discontinuations. Tolerability data were not reported.

The non-significant improvement in behavioral symptoms calls for further long-term trials. This limitation highlights the need for additional research to confirm findings. The study did not support changing the current policy regarding the coverage of the French model of occupational therapy. Funding or conflicts of interest were not reported. The study phase was not reported. The publication type was not reported.

Clinical implications suggest that extending occupational therapy by 4 months does not yield significant behavioral benefits in this population. Practitioners should consider maintaining current policies regarding coverage. Questions remain unanswered regarding long-term effects and secondary outcomes. The lack of reported safety data limits the ability to assess risk-benefit profiles fully.

This trial provides evidence that extended occupational therapy does not significantly alter behavioral symptoms in community-dwelling adults with mild-to-moderate dementia. The findings support the continuation of standard care protocols in this context. Further research is needed to address the identified limitations and explore other therapeutic durations or intensities.
