Patient Factors and Perioperative Outcomes Affect Hospital Consumer Assessment of Healthcare Providers and Systems Survey Response Rates After Primary Total Hip Replacement. (April 2021) - Mercier, Michael R.
Abstract : Introduction: The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is a federally mandated survey that assesses patient satisfaction after hospitalization. It has been noted that a minority of patients actually return the survey. Potential bias in who does and does not respond to the survey (nonresponse bias) after total hip arthroplasty (THA) may affect the survey results. Methods: All adult patients undergoing inpatient elective primary THA between February 2013 and May 2020 at a single institution were selected for retrospective analysis. After discharge, all had been mailed the HCAHPS survey, and the primary outcome for the current study was survey return. Patient characteristics and 30-day perioperative outcomes were assessed. Univariate and multivariate analyses were performed to determine correlations between the above variables and HCAHPS survey return status. Results: Of 3, 310 THA patients analyzed, 1, 049 (31.69%) returned the HCAHPS surveys. On multivariate regression analyses, patients who did not return the survey were more likely to have a higher American Society of Anesthesia score (score of three or higher, odds ratio [OR] = 2.27; P < 0.001), be more functionally dependent (OR = 2.69; P = 0.005), or be Black/African American (OR = 3.40; P < 0.001). Similarly, patients who did not return the survey were more likely to have had any adverse event (OR = 1.80; P = 0.012), major adverse event (OR = 2.88; P = 0.007), readmission (OR = 2.13; P < 0.001), be discharged to a place other than home (OR = 1.71; P < 0.001), or stay in the hospital for longer than 3 days (OR = 1.89; P < 0.001). Discussion: After THA, the HCAHPS survey response rate was only 31.69% and completion of the survey correlated with demographic and perioperative variables. These findings suggest that the HCAHPS survey results should be interpreted as a skewed sample of the true surgical patient population. Nonresponse bias is an important factor to consider when evaluating healthcare quality, patient satisfaction survey results, and their effects on federal hospital reimbursement rates.
