Is the Hospital Value-Based Purchasing Program Associated with Reduced Hospital Readmissions?

INTRODUCTION: Hospital readmissions have been associated with adverse outcomes and elevated financial costs to patients, families, and hospitals across the United States. Historically, nearly 20% of all Medicare discharges had a readmission within 30 days. In an effort to address this issue, the Affordable Care Act (ACA) established the Hospital Readmission Reduction Program (HRRP) in 2012 to positively influence readmissions associated with acute myocardial infarction, chronic obstructive pulmonary disease, heart failure, pneumonia, coronary artery bypass graft surgery, and total hip and/or knee arthroplasty. However, as recently as 2018, there were still 3.8 million 30-day all-cause adult hospital readmissions, with a 14% readmission rate and an average readmission cost of $15,200. The ACA also produced the Hospital Value-Based Purchasing (HVBP) program with the stated intent to (1) reduce mortality and complications, (2) reduce healthcare-associated infections, (3) increase patient safety, (4) improve the patient experience, and (5) increase efficiency and reduce costs. Given the costs and quality implications of an average readmission, it is logical to believe that HVBP eligible hospitals are simultaneously seeking to meet the goals of both programs. However, to date, no studies have examined if that is the case. Thus, in this study, we seek to determine if HVBP eligible hospitals are associated with a reduction in the core set of HRRP readmission rates better than the facilities that are not eligible for the HVBP program. METHODS: Hospital-level data from calendar year 2019 for 3,276 short-term acute care hospitals in the United States were evaluated using multivariate regression analysis to examine the readmission rate performance between 2,719 HVBP eligible hospitals and 557 ineligible hospitals. RESULTS: Our six separate multivariable linear regressions revealed a statistically significant and positive association between HVBP participation and readmission rates after controlling for numerous organizational, clinical complexity, and environmental factors. In each case, the magnitude of the positive directional association is moderate, ranging from and increase of +0.19% (pneumonia readmissions) to as high as +0.37% (all cause readmissions) for HVBP eligible hospitals. When considered in the context of the average number of discharges in our data set (x- = 9570), a third of a percent increase from the average 15.56% all cause readmissions to 16.08% in HVBP eligible hospitals equates to 50 additional readmissions annually (9570 × 15.56% = 1,489 vs 9570 × 16.08% = 1,539). At an average cost of $15,200 per readmission, which equates to an average additional cost to the average HVBP eligible hospital in excess of $760,000. DISCUSSION: The fact that there is a positive association between HVBP participating hospitals and readmissions at all, and that the same effect appears to be persistent across all dependent measures is concerning. One would logically expect hospitals that are focused on quality-based care to thoroughly care for individuals in order for them to not be readmitted to the hospital. The results provided do not necessarily prove that either program is not working. But they also do not confirm that the HVBP and HRRP programs are working together and accomplishing what they were originally designed to do: improve patient care and lower health-care costs.
