Effectiveness and Cost-Effectiveness of Occupation-Based Occupational Therapy Using the Aid for Decision Making in Occupation Choice (ADOC) for Older Residents: Pilot Cluster Randomized Controlled Trial.

BACKGROUND: Care-home residents are mostly inactive, have little interaction with staff, and are dependent on staff to engage in daily occupations. We recently developed an iPad application called the Aid for Decision-making in Occupation Choice (ADOC) to promote shared decision-making in activities and occupation-based goal setting by choosing from illustrations describing daily activities. This study aimed to evaluate if interventions based on occupation-based goal setting using the ADOC could focus on meaningful activities to improve quality of life and independent activities of daily living, with greater cost-effectiveness than an impairment-based approach as well as to evaluate the feasibility of conducting a large cluster, randomized controlled trial. METHOD: In this single (assessor)-blind pilot cluster randomized controlled trial, the intervention group (ADOC group) received occupational therapy based on occupation-based goal setting using the ADOC, and the interventions were focused on meaningful occupations. The control group underwent an impairment-based approach focused on restoring capacities, without goal setting tools. In both groups, the 20-minute individualized intervention sessions were conducted twice a week for 4 months. MAIN OUTCOME MEASURES: Short Form-36 (SF-36) score, SF-6D utility score, quality adjusted life years (QALY), Barthel Index, and total care cost. RESULTS: We randomized and analyzed 12 facilities (44 participants, 18.5% drop-out rate), with 6 facilities each allocated to the ADOC (n = 23) and control (n = 21) groups. After the 4-month intervention, the ADOC group had a significantly greater change in the BI score, with improved scores (P = 0.027, 95% CI 0.41 to 6.87, intracluster correlation coefficient = 0.14). No other outcome was significantly different. The incremental cost-effectiveness ratio, calculated using the change in BI score, was $63.1. CONCLUSION: The results suggest that occupational therapy using the ADOC for older residents might be effective and cost-effective. We also found that conducting an RCT in the occupational therapy setting is feasible. TRIAL REGISTRATION: UMIN Clinical Trials Registry UMIN000012994.

Utilization of the iPad application: Aid for Decision-making in Occupation Choice.

The purpose of the study was to develop and evaluate an iPad (Apple) application, Aid for Decision-making in Occupation Choice (ADOC), so as to promote shared decision-making in an occupation-based goal setting. This application involves the client choosing from 94 illustrations describing daily activities related to the category of "activities and participation". One hundred occupational therapy clients evaluated the ADOC for goal setting; the clients and 37 occupational therapists underwent a survey to determine their perceptions of decision-making in the goal setting. More than 90% of the clients felt that they could give their opinions using the ADOC regarding goal setting. The majority of the occupational therapists (>90%) felt that ADOC would be useful in their clinical practice for setting client goals. The results indicated that ADOC is a useful and acceptable tool for both clients and occupational therapists in shared decision-making in occupation-based goal setting.
