The Affordable Care Act (ACA) established the Hospital-Acquired Condition (HAC) Reduction Program. The Centers for Medicare and Medicaid Services (CMS) established a total HAC scoring methodology to rank hospitals based upon their HAC performance. Hospitals that rank in the lowest quartile based on their HAC score are subject to a 1% reduction in their total Medicare reimbursements. In FY 2017, 769 hospitals incurred payment reductions totaling $430 million. This study analyzes how improvements in the rate of catheter-associated urinary tract infections (CAUTI), based on the implementation of a cranberry-treatment regimen, impact hospitals' HAC scores and likelihood of avoiding the Medicare-reimbursement penalty.
A simulation model is developed and implemented using public data from the CMS' Hospital Compare website to determine how hospitals' unilateral and simultaneous adoption of cranberry to improve CAUTI outcomes can affect HAC scores and the likelihood of a hospital incurring the Medicare payment reduction, given results on cranberry effectiveness in preventing CAUTI based on scientific trials. The simulation framework can be adapted to consider other initiatives to improve hospitals' HAC scores.
Nearly all simulated hospitals improved their overall HAC score by adopting cranberry as a CAUTI preventative, assuming mean effectiveness from scientific trials. Many hospitals with HAC scores in the lowest quartile of the HAC-score distribution and subject to Medicare reimbursement reductions can improve their scores sufficiently through adopting a cranberry-treatment regimen to avoid payment reduction.
The study was unable to replicate exactly the data used by CMS to establish HAC scores for FY 2018. The study assumes that hospitals subject to the Medicare payment reduction were not using cranberry as a prophylactic treatment for their catheterized patients, but is unable to confirm that this is true in all cases. The study also assumes that hospitalized catheter patients would be able to consume cranberry in either juice or capsule form, but this may not be true in 100% of cases.
Most hospitals can improve their HAC scores and many can avoid Medicare reimbursement reductions if they are able to attain a percentage reduction in CAUTI comparable to that documented for cranberry-treatment regimes in the existing literature.
《平价医疗法案》(ACA)设立了医院获得性疾病(HAC)减少计划。医疗保险和医疗补助服务中心(CMS)制定了一套完整的HAC评分方法,根据医院的HAC表现对其进行排名。HAC得分处于最低四分位的医院,其医疗保险总报销额将减少1%。2017财年,769家医院的付款减少额总计达4.3亿美元。本研究分析了基于蔓越莓治疗方案的实施,导尿管相关尿路感染(CAUTI)发生率的改善如何影响医院的HAC得分以及避免医疗保险报销处罚的可能性。
利用CMS“医院比较”网站的公开数据开发并实施了一个模拟模型,以确定在基于科学试验得出蔓越莓预防CAUTI有效性结果的情况下,医院单方面及同时采用蔓越莓来改善CAUTI结果如何影响HAC得分以及医院遭受医疗保险付款减少的可能性。该模拟框架可进行调整,以考虑其他改善医院HAC得分的举措。
假设科学试验的平均有效性,几乎所有模拟医院通过采用蔓越莓作为CAUTI预防措施,提高了其总体HAC得分。许多HAC得分处于HAC得分分布最低四分位且面临医疗保险报销减少的医院,通过采用蔓越莓治疗方案,其得分可得到充分提高,从而避免付款减少。
该研究无法精确复制CMS用于确定2018财年HAC得分的数据。该研究假设面临医疗保险付款减少的医院未将蔓越莓用作其导尿患者的预防性治疗,但无法证实所有情况下均如此。该研究还假设住院导尿患者能够饮用蔓越莓汁或服用蔓越莓胶囊,但并非100%的情况都是如此。
如果大多数医院能够将CAUTI降低到与现有文献中蔓越莓治疗方案所记录的百分比相当的水平,那么它们可以提高HAC得分,并且许多医院可以避免医疗保险报销减少。
