Patient Factors and Perioperative Outcomes Affect Hospital Consumer Assessment of Healthcare Providers and Systems Survey Response Rates After Primary Total Hip Replacement.

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.
