Factors influencing patient satisfaction with GI endoscopy

Background: A modified Group Health Association of America-9 survey (mGHAA-9) was recently proposed for measurement of patient satisfaction with endoscopy. It is unknown whether the mGHAA-9 addresses the issues most important to this outcome. Methods: A 15-item survey of factors potentially important to patient satisfaction with endoscopy was developed, including the 6 core mGHAA-9 items. Respondents were asked to rank the factors from 1 to 15 (1 = most important to l5 = least important to satisfaction). Two groups were surveyed: (1) patients with prior endoscopy experience and (2) physician endoscopists. Item rank distributions overall and by patient age, gender, and procedure experience were examined. Results: Of 559 outpatients surveyed, 437 (78%) provided complete responses. The mean patient age was 59 years (48.7% female, 45.3% male, 6% not stated). The number 1 ranked factor was the endoscopist's technical skills (median ranking (mr) = 1), an item included in the mGHAA-9. Pain control, a factor not assessed by the mGHAA-9, was second (mr = 4), and ranked number 1 by 16% of patients. Item rankings were consistent across patient subgroups. Relative to patients, endoscopists underprioritized preprocedure and postprocedure communication. Conclusions: The mGHAA-9 has inadequate content validity for measurement of patient satisfaction with endoscopy because it does not assess pain control. However, endoscopysatisfaction measurement with a single, universally applied instrument appears feasible.
