Impact of Medicare's Nonpayment Program on Venous Thromboembolism Following Hip and Knee Replacements.

ABSTRACT:

Objective

To determine whether Medicare's Nonpayment Program was associated with decline in venous thromboembolism (VTE) following hip and knee replacements; and whether the decline was greater among hospitals at risk of larger financial losses from the Program.

Data sources

State Inpatient Database for New York (NY) from 2005 to 2013.

Study design

The primary outcome was an occurrence of VTE. Medicare Utilization Ratio (MUR), which is the proportion of inpatient days in a hospital that is financed by Medicare, represented a hospital's financial sensitivity. We used hierarchical logistic regressions with difference-in-differences estimation to study the Program effects.
