Impact of the recommendations made by Spanish Club for the Study of Helicobacter pylori on eradication indications

Abstract

Aim: A Spanish Consensus Conference had been arranged by the Spanish Club for the Study of Helicobacter pylori to encourage the use of eradication regimens in appropriate indications. The aim of our study was to assess whether the publication of these recommendations in November 1999 induced a change on the indications of eradication in the referring primary care district.

Method: Patients who had undergone Helicobacter pylori eradication therapy indicated by a gastroenterologist and referred to perform the 13C-labelled marked urea breath test were evaluated. Indications of eradication therapy were analysed and divided in: a) use of Conference recommended procedures (duodenal or gastric ulcer, erosive duodenitis, gastric MALT lymphoma and after resection of gastric adenocarcinoma); and b) other procedures not included in the recommendations (the rest). Indications established during former and latter years of publication of the Club's recommendations were compared.

Results: A total of 659 established eradications in 1999 against 537 in 2000, were studied. Regarding established eradications in 1999, 418 out of 659 (63%) followed the recommendations made by the Spanish Club, while 241 (37%) did not. In 2000, the proportion of eradication therapy administered using the recommendations made by the Spanish Club was similar to previous year: 338 (63%) followed the recommendations, against 199 (37%) that did not (p = not significant). In both years, considering those indications not recommended, patients either with superficial chronic gastritis with or without dyspepsia or with gastrooesophageal reflux disease were the main disorders to indicate eradication therapy.

Conclusions: The recommendations of the Spanish Helicobacter pylori Study Club have not triggered a significant change after their publication on the indications for Helicobacter pylori eradication therapy in the setting studied.
