Shortly after Medicare implemented post-acute care payment reforms, the COVID-19 pandemic began, but little is known about how these reforms and the pandemic impacted admissions to the most common post-acute settings-skilled nursing facilities (SNF) and home health agencies (HHAs)-for the full Medicare fee-for-service population.
Using 100% of Medicare fee-for-service data, we conducted adjusted interrupted time series analyses of 31,730,994 hospital stays of all adult beneficiaries discharged alive from the hospital between 2018 and 2021 to examine whether payment reforms and the pandemic were associated with differences in admissions to SNFs and HHAs compared to pre-reform and pre-COVID (baseline) trends.
At baseline, an average 18.0% of hospitalized beneficiaries were admitted to SNFs and 14.8% to HHAs. While SNF payment reform in October 2019 was associated with an immediate reduction in SNF admissions, a positive temporal trend reversed this decrease in admissions. HHA payment reform implemented in January 2020 was associated with increased HHA admissions compared to baseline. Post-COVID, admissions to SNF declined to 15.5% of patients being discharged from hospitals and HHA admissions increased to 19.2%.
SNF and HHA payment reforms were associated with small increases in admissions to their respective settings, suggesting that Medicare reforms did not negatively impact access. However, the baseline trends of decreasing admissions to SNF and increasing HHA admissions were greatly accelerated by the COVID-19 pandemic. Results highlight changes in the demand for these settings, which must be recognized in policy efforts and research examining impacts on specific patient populations.
医疗保险实施急性后护理支付改革后不久,新冠疫情爆发,但对于这些改革和疫情如何影响整个医疗保险按服务收费人群进入最常见的急性后护理机构——熟练护理设施(SNF)和家庭健康机构(HHA)的情况,我们知之甚少。
我们使用100%的医疗保险按服务收费数据,对2018年至2021年期间所有成年受益人的31730994次出院进行了调整后的中断时间序列分析,以研究与改革前和新冠疫情前(基线)趋势相比,支付改革和疫情是否与进入SNF和HHA的差异有关。
在基线时,平均18.0%的住院受益人进入SNF,14.8%进入HHA。2019年10月的SNF支付改革与SNF入院人数立即减少有关,但积极的时间趋势扭转了入院人数的下降。与基线相比,2020年1月实施的HHA支付改革与HHA入院人数增加有关。新冠疫情后,进入SNF的患者比例降至出院患者的15.5%,进入HHA的患者比例增至19.2%。
SNF和HHA支付改革与各自机构入院人数的小幅增加有关,这表明医疗保险改革并未对就医机会产生负面影响。然而,新冠疫情极大地加速了SNF入院人数下降和HHA入院人数增加的基线趋势。结果突出了对这些机构需求的变化,在政策努力和研究对特定患者群体的影响时必须认识到这一点。
