Three case-type classifications: suitability for use in reimbursing hospitals
Medical Care
|May 1, 1982
Summary
This study found that current hospital case-type classifications do not adequately explain patient charges for reimbursement. Further development is needed for effective hospital cost management and payment systems.
Area of Science:
- Health Services Research
- Healthcare Management
- Medical Economics
Background:
- Effective hospital reimbursement schemes rely on accurate case-type classifications to predict patient charges.
- Existing methods like the Commission on Professional and Hospital Activities, Diagnosis-Related Groups (DRGs), and Staging have been evaluated for their predictive power.
Purpose of the Study:
- To compare the variance in total patient charges explained by three distinct case-type classifications.
- To assess the suitability of these classifications for hospital reimbursement applications.
Main Methods:
- A nested analysis of variance was conducted across 50 hospitals.
- The percentage of variance in total patient charges was calculated for each classification using full, truncated, and log-transformed datasets.
Main Results:
- None of the evaluated case-type classifications sufficiently accounted for the variance in total patient charges.
- The predictive power of these classifications was insufficient for direct application in standard cost-based reimbursement.
Conclusions:
- Current case-type classifications are inadequate for straightforward use in hospital reimbursement mechanisms.
- Advancements in case-type classification are necessary to develop more suitable systems for healthcare payment and cost allocation.
