ABSTRACT:

Objective

To compare cost estimates for hospital stays calculated using diagnosis-related group (DRG) weights to actual Medicare payments.

Data sources/study setting

Medicare MedPAR files and DRG tables linked to participant data from the Study of Osteoporotic Fractures (SOF) from 1992 through 2010. Participants were women age 65 and older recruited in three metropolitan and one rural area of the United States.

Costs were estimated using DRG payment weights for 1,397 hospital stays for 795 SOF participants for 1 year following a hip fracture. Medicare cost estimates included Medicare and secondary insurer payments, and copay and deductible amounts.

Principal findings
