The Italian Society for Digestive Endoscopy (SIED) accreditation and quality improving project based on international standards

Accreditation program for gastrointestinal endoscopes reprocessing in Italy: An on-site survey

Background and study aims  Endoscope reprocessing has been associated with a variable failure rate. Our aim was to present an overview on current practices for reprocessing in Italian facilities and discuss the principle critical points. Methods  In 2014 the Italian Society for Digestive Diseases implemented an accreditation program in collaboration with an independent organization for certification and with the Italian Association for Endoscopy Technical Operators. During a 1-day site visit of the endoscopy center, two endoscopists, one nurse, and the representative of the certification body evaluated the endoscope reprocessing. Results  As of July 1, 2020, 28 endoscopy centers had been accredited. Ten centers are completing the measures to correct deficiencies found at the visit. Three centers withdrew from the program. The accreditation program has found variations between the various centers, confirming the poor compliance with guidelines. Major deviations from the standards, established by the model before the site visit according to national and international guidelines, concerned instrument cleaning (44.7 % of the centers), instrument storage (23.7 %), and microbiological tests (31.6 %). Conclusions  Our overview demonstrated the lack of many reprocessing phases, which are important to prevent endoscopy-associated infections. Accreditation can achieve a transformation in quality and safety of reprocessing with the Italian centrally-led approach.

Accreditation of digestive endoscopy services: a method of quality assuring?

INTRODUCTION

Accreditation is one method of assuring quality, but the evidence base in support of service accreditation is mixed. More recent experiences indicate that accreditation may accelerate improvements.

AREAS COVERED

Our aim is focused on endoscopy service accreditation and we conducted a literature search using Medline (via Pubmed) and the Cochrane Center Register of Controlled Trials up to January 2020.

EXPERT OPINION

Worldwide numerous centers fail to meet important quality indicators as suggested by international guidelines. Accreditation can provide means for detecting many problems and correcting them by implementing agreed standards.

Review: Diagnosis of Helicobacter pylori infection

New imaging techniques are still the topic of many evaluations for both the diagnosis of Helicobacter pylori gastritis and the detection of early gastric cancer. Concerning invasive tests, there were studies on the reuse of the rapid urease test material for other tests, and a novel fluorescent method to be used for histology but with limited sensitivity. Progress occurred essentially in the molecular methods area, especially next-generation sequencing which is applied to detect both H pylori and the mutations associated with antibiotic resistance. For non-invasive tests, a few studies have been published on the validity of breath collection bags, the shortening of the testing time, the performance of different analysers or the added value of citric acid in the protocol. The accuracy of serological immunochromatographic tests is also improving. Multiplex serology detecting antibodies to certain proteins allows confirmation of a current infection. Dried blood spots can be used to collect and store blood without a loss of accuracy. Finally, the serum antibody titer can be useful in predicting the risk of gastric cancer. Several stool antigen tests were evaluated with good results, and a novel test using immunomagnetic beads coated with monoclonal antibodies is potentially interesting. PCR detection in stools can also be effective but needs an efficient DNA extraction method. The use of easyMAG^® (bioMérieux) combined with Amplidiag® H pylori + ClariR (Mobidiag) appears to be powerful.
