A trial based economic evaluation of occupational therapy discharge planning for older adults: the HOME randomized trial

Abstract

Objective:

To compare the cost effectiveness of two occupational therapy–led discharge planning interventions from the HOME trial.

Design:

An economic evaluation was conducted within the superiority randomized HOME trial to assess the difference in costs and health-related outcomes associated with the enhanced program and the in-hospital consultation. Total costs of health and community service utilization were used to calculate incremental cost-effectiveness ratios, activities of daily living and quality-adjusted life years.

Setting:

Medical and acute care wards of Australian hospitals (n=5).

Subjects:

A total of 400 people ≥ 70 years of age.

Interventions:

Participants were randomized to either (1) an enhanced program (HOME), involving pre/post discharge visits and two follow-up phone calls, or (2) an in-hospital consultation using the home and community environment assessment and the Lawton Instrumental Activities of Daily Living assessment.

Main measures:

Nottingham Extended Activities of Daily Living (global measure of activities of daily living) and SF-12V2, transformed into SF-6D (quality-adjusted life year) measured at baseline and three months post discharge.

Results:

The cost of the enhanced program was higher than that of the in-hospital consultation. However, a higher proportion of patients showed improvement in activities of daily living in the enhanced program with an incremental cost-effectiveness ratio of $61,906.00 per person with clinically meaningful improvement.

Conclusion:

Health services would not save money by implementing the enhanced program as a routine intervention in medical and acute care wards. Future research should incorporate longer time horizons and consider which patient groups would benefit from home visits.
