Open access gastroscopy: too much to swallow?

OBJECTIVES

To ascertain the proportion of endoscopic examinations with normal findings in patients referred for gastroscopy through hospital medical staff or directly by their general practitioner and to assess the likely effect of targeting endoscopy in older patients.

DESIGN

Retrospective audit of the gastroscopy practice of one consultant from 1986 to 1988 from information recorded on a standard form completed at the time of the examination, which contained details of patients, their endoscopic findings, and mode of referral (open access or clinic).

SETTING

One district general hospital.

PATIENTS

1545 Consecutive patients from primary catchment area attending for their first gastroscopy; 454 were referred through the outpatient clinic or by hospital colleagues (clinic group) and 1091 were accepted for endoscopy solely on their general practitioner's clinical diagnosis (open access group).

RESULTS

Similar numbers (about 40%) of examinations with normal findings were performed in each group, although in patients aged over 40 the proportion with normal findings was significantly higher in the clinic group (p less than 0.03). Endoscopic evidence of gastro-oesophageal reflux disease, peptic ulceration, and gastroduodenal inflammation was equally common in each group; upper gastrointestinal malignancy, however, was significantly more common in patients referred through hospital doctors (5%, 23/454 v 2%, 22/1091 respectively; p less than 0.005) (although many of these patients had already been extensively investigated).

IMPLICATIONS

Open access gastroscopy does not increase the number of unnecessary examinations and should become more widely available. Targeting this service to patients aged over 40 would reduce the number of requests but increase the diagnostic yield.
