Investigators of this study found implementation of a bundled payment model for lower extremity joint replacement in a hospital system correlated with hospital savings and lower Medicare payments.

Perspective from Mike McCaslin, CPA

Researchers performed an observational study that included 3,942 patients who underwent lower extremity total joint replacement at the Baptist Health System while the system participated in the voluntary Acute Care Episodes and Bundled Payments for Care Improvement demonstration projects under the Comprehensive Care for Joint Replacement bundled payment model. There period studied spanned from 2008 to 2015. Investigators calculated the 30-day readmission rate, average Medicare payments per episode, ER visits, length of stay, hospital savings due to changes in internal hospital costs and post-acute care (PAC) spending.

Findings showed the Medicare episode costs for 3,739 of patients without any complications decreased on average 20.8% from $26,785 to $21,208. Investigators noted for 204 joint replacement episodes with complications, the Medicare episode costs decreased from $38,537 to $33,216 or 13.8%. Readmissions dropped by 1.4% and ER visits declined by 0.9%. In addition, investigators found a 67% decrease in the rates of prolonged length of stay.

According to researchers, 51.2% of the hospital savings overall came from reductions in internal costs, with 48.8% of savings coming from reductions in PAC spending. Per case, the implant costs decreased on average by $1,920.68. PAC spending on average decreased by $2,443.12 reportedly due to inpatient rehabilitation and skilled nursing facilities with the exception that the bundles were financially responsible for PAC. by Monica Jaramillo
