Savings and outcomes under Medicare's bundled payments initiative for skilled nursing facilities

Background Model 3 of Medicare's Bundled Payments for Care Improvement (BPCI) was a voluntary alternative payment model that held participating skilled nursing facilities (SNFs) accountable for 90-day costs of care. Its overall impact on Medicare spending and clinical outcomes is unknown. Methods Retrospective cohort study using Medicare claims from 2012 to 2017. We used an interrupted time-series design to compare participating vs matched control SNFs on total 90-day Medicare payments and payment components (initial SNF stay, readmissions, and outpatient/clinician), case mix (volume, proportion Medicaid, proportion black, number of comorbidities), and clinical outcomes (90-day readmission, mortality and healthy days at home, and length of initial SNF stay), overall and among key subgroups with frailty or dementia, for 47 of the 48 conditions in the program (excluding major lower extremity joint replacement). Results Our sample included 1001 participating and 3873 matched control SNFs. At baseline, total Medicare institutional payments were increasing at BPCI SNFs at a rate of $121 per episode per quarter; during the intervention period, payments decreased at a rate of -$398/episode/quarter. Among controls, payments were stable in the baseline period (+$17/episode/quarter) but decreased at -$424/episode/quarter during the intervention period, yielding a nonsignificant difference in slope changes of -$79/episode/quarter (95% confidence interval [CI] -$188, $31, p = 0.16). However, among patients with frailty, spending declined by $620/episode/quarter in the BPCI group, compared with $330/episode/quarter in the non-BPCI group, for a difference in slope changes of -$289 (95% CI -$482, -$96, p = 0.003). There were no differences in the change in slopes in case selection or clinical outcomes overall or in any clinical subgroup. Conclusions SNF participation in BPCI was associated with no overall differential change in total Medicare payments per episode, case selection, or clinical outcomes. Exploratory analyses revealed a decrease in Medicare payments in patients with frailty that may warrant further study.

Automated summary

This study retrospectively analyzed Medicare claims data to evaluate the impact of Medicare's Bundled Payments for Care Improvement (BPCI) Model 3 on skilled nursing facilities (SNFs). The findings showed that overall Medicare payments per episode did not differ significantly between participating and control SNFs, but there was a decrease in spending for patients with frailty in the BPCI group, warranting further investigation.
