Press Ganey Surveys in Patients Undergoing Upper-Extremity Surgical Procedures: Response Rate and Evidence of Nonresponse Bias.

BACKGROUND
Patient satisfaction surveys are important measures of the patient experience that provide data for quality improvement. The purpose of this study was to establish the response rate and the factors associated with the completion of the Press Ganey (PG) Ambulatory Surgery Survey (PGAS) in patients who underwent ambulatory upper-extremity surgical procedures.


METHODS
A prospective orthopaedic registry at a single academic ambulatory surgical center was retrospectively reviewed for patients who underwent an upper-extremity surgical procedure from 2015 to 2019. The institutional PG database was queried to determine the patients who completed the PGAS postoperatively. The response rate was calculated, and baseline characteristics and patient-reported outcome measures were compared between responders and nonresponders.


RESULTS
Of the 1,489 patients included, 201 (13.5%) were responders and 1,288 (86.5%) were nonresponders. Differences existed in baseline characteristics between groups, with responders being significantly older (p = 0.004) and having significantly higher proportions of White race (p < 0.001), college education (p = 0.011), employment (p = 0.005), marriage (p = 0.006), and higher income earners (p < 0.001). Responders had significantly better baseline Patient-Reported Outcomes Measurement Information System scores across multiple domains (p < 0.05), but these differences were not clinically meaningful.


CONCLUSIONS
PGAS response rates were low (13.5%), and differences between responders and nonresponders may be utilized by hospitals to target feedback from underrepresented patient populations. Surgeons, policymakers, and health-care administrators should use caution with the interpretation of PGAS results because responders may not be representative of all patients.
