Activity-based occupational therapy intervention for delirium superimposed on dementia in nursing home setting: a feasibility study

Objective Multi-component interventions can reduce delirium incidence. Occupational therapy (OT) has been effective in the management of dementia. We designed a real-world feasibility study of an OT intervention in the management of delirium superimposed on dementia (DSD). Methods We included a convenient sample of 22 patients older than 65 years of age with delirium and moderate dementia admitted to a nursing home (NH). The OT procedures were standardized according to the level of agitation or sedation of the patient and based on a structured OT evaluation. The Canadian Occupational Performance Measure (COPM) was used to evaluate the proxy perception of performance in the daily activities at baseline and at delirium resolution. Results The mean age was 86.45 ± 6.46 years. The first daily treatment was delivered in the entire sample, while the second was delivered in 63.46% on day 1, 72.72% on day 2, 25% on day 3, 66.67% on day 4, 100% on days 5 and 6. The main time of the first daily treatment varied, day 1 through day 6, from 14.8 ± 8.5 to 20 ± 0 min; while the second daily treatment, in the same period, from 3.9 ± 6.7 to 20.1 ± 0 min. The mean time of the first treatment varied day 1 through day 6 from 14.8 ± 8.5 to 20 ± 0 min, while the second treatment from 3.9 ± 6.7 to 20.1 ± 0 min. The COPM proxy performance and proxy satisfaction increased from delirium onset to delirium resolution. Conclusions This is the first study to report the feasibility of an OT intervention for the management of DSD in a NH setting. The results are important to support future trials on delirium management in a setting often understudied and underrepresented.
