Researchers from Rochester and Minneapolis, Minnesota, USA examined whether the modified Group Health Association of America-9 survey (mGHAA-9) adequately assesses patient satisfaction with endoscopy.
The team developed a 15-item survey of factors potentially important to patient satisfaction with endoscopy, including the 6 core mGHAA-9 items.
Respondents were asked to rank the factors from 1 to 15 (1 = most important to 15 = least important to satisfaction).
Two groups were surveyed. The first included patients with prior endoscopy experience and the second included physician endoscopists.
Item rank distributions were examined overall and also by patient age, gender, and procedure experience.
A total of 559 outpatients were surveyed. 78% of these provided complete responses to the survey.
Endoscopy satisfaction measurement with a single, universally-applied instrument is feasible.

The mean patient age was 59 years (49% female, 45% 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 were found to under-prioritized pre-procedure and post-procedure communication.
Dr Robert F. Yacavone, of the Mayo Clinic and Mayo Foundation, Rochester, said on behalf of the group, "The mGHAA-9 has inadequate content validity for measurement of patient satisfaction with endoscopy because it does not assess pain control."
"However, endoscopy satisfaction measurement with a single, universally-applied instrument appears feasible," he concluded.
