Summary
Subacute rehabilitation is more cost-effective than acute rehabilitation, despite similar patient characteristics. Acute care yielded greater functional gains but at a significantly higher cost per patient and per functional improvement.
Area of Science:
- Rehabilitation Medicine
- Health Services Research
- Stroke Recovery
Background:
- Subacute rehabilitation offers a less intensive alternative to traditional inpatient rehabilitation.
- Understanding the comparative effectiveness and cost of subacute versus acute rehabilitation is crucial for healthcare policy.
- Stroke rehabilitation services are evolving, necessitating evidence-based comparisons.
Purpose of the Study:
- To retrospectively compare patient characteristics, treatment intensity, functional outcomes, and cost-effectiveness of acute rehabilitation versus subacute rehabilitation for stroke patients.
- To evaluate the efficiency of different rehabilitation settings in achieving functional gains and community discharge.
Main Methods:
- Retrospective analysis of 331 acute rehabilitation and 97 subacute rehabilitation patients from 1990-1991.
- Comparison of patient demographics, treatment intensity (total and daily hours), charges, and functional impairment measures (Functional Independence Measure - FIM).
- Cost-effectiveness analysis based on charge per successful discharge and charge per FIM point gain.
Main Results:
- Few significant differences in patient characteristics were observed between acute and subacute groups.
- Acute rehabilitation patients received twice the treatment intensity and incurred double the daily charges compared to subacute patients.
- While acute rehabilitation led to greater FIM gains, the proportion of community discharges was similar; however, the cost per successful discharge and per FIM point was substantially higher in acute care.
Conclusions:
- Subacute rehabilitation demonstrates greater cost-effectiveness compared to acute rehabilitation.
- Despite higher costs, acute rehabilitation resulted in more significant functional improvements.
- Further research is recommended to inform policy decisions regarding the optimal use of subacute rehabilitation services.
