Hospital Consumer Assessment of Healthcare Providers and Systems Scores Do Not Predict Outcomes After Total Hip Arthroplasty.

BACKGROUND: With the establishment of the Hospital Value-Based Purchasing program, the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) score has been incorporated into the calculation of the total performance score, which determines redistribution of up to 2% of Medicare payments. This study aims to assess whether the HCAHPS score correlates with validated outcome measures after total hip arthroplasty.

METHODS: Data from 63 patients who underwent a total hip arthroplasty and completed both an HCAHPS score and patient-reported outcome measures (PROMs) at our institution during the study period from January 1, 2015 to September 2016 were analyzed. The HCAHPS overall hospital rating scores were correlated with the preoperative to postoperative change in validated PROMs, namely EuroQol-EQ-5D Instrument and Hip Disability and Osteoarthritis Outcome Score.

RESULTS: There was no statistically significant correlation between the HCAHPS overall hospital rating score and PROMs.

CONCLUSION: This study shows a lack of correlation between established validated PROMs used in orthopedic surgery, and the HCAHPS survey scores, an important determinant of compensation in the pay-for-performance reimbursement models.
