Abstract 14996: Healthcare Resource Utilization and Costs in Congestive Heart Failure 90-day Episodes Within the Bundled Payment for Care Initiative (BPCI) Model 2, 2016-2018

Abstract

Introduction: Congestive heart failure (HF) is the fourth most commonly selected clinical episode among Model 2 participants of the Medicare Bundled Payments for Care Improvement (BPCI) Initiative. This study describes utilization of pharmacologic therapies, hospital readmission rates, and HF episode costs within the BPCI framework. Methods: The 100% sample of Medicare FFS enrollment/claims were used to identify acute hospital stays with a MS-DRG 291/292/293 between 1JAN2016 and 31DEC2018. A HF episode consisted of the initial hospital stay and all Part A & B covered services up to 90-days post-discharge. Prescription fills for angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), or angiotensin receptor-neprilysin inhibitors (ARNI) during the 90 days post-discharge were captured. Rates of all-cause and HF readmissions were reported per 10,000 episodes during the 30-, 60-, and 90-days post-discharge period. Total episode costs were defined as the sum of Medicare payments for the initial hospital stay plus all Part A & B covered medical services in the 90-day post-discharge. Results: The sample included 634,307 HF episodes. Patients received ARNIs in 3%, ACEIs/ARBs in 45%, and neither in 52% of the episodes, respectively. All-cause hospital readmission rates were 2,503, 4,465, and 6,368 per 10,000 episodes during the 30-, 60-, and 90-day periods. The 30-, 60-, and 90-day HF readmission rates were 958, 1,696, and 2,394 per 10,000 episodes. Total mean 90-day episode cost was $20,122, of which $8,002 was attributable to hospital readmissions. Conclusions: Hospital readmissions are frequent for HF patients and contribute a notable proportion of overall HF BPCI episode costs. BPCI participants may consider improving utilization of guideline directed medical therapies for HF, including ACEIs/ARBs and ARNI, as a strategy for reducing hospital readmissions and associated costs.
