Colonoscopy practice in Italy: a prospective survey on behalf of the Italian Association of Hospital Gastroenterologists

BACKGROUND: Examining the current practice is important for the benchmarking of quality of colonoscopy and the comparison with the standards and recommendations expected by professional societies. AIM: To describe colonoscopy practice in Italy, on the basis of prospective analysis of a large number of examinations performed by operators with different levels of expertise in a wide range of unselected centres. DESIGN AND SETTING: Cross-sectional, prospective and multicentre study. METHODS: The main features of each endoscopy centre (structure indicators) were collected through the use of a standardised questionnaire. A second questionnaire was used to prospectively record details of all the consecutive colonoscopies performed in a 2-week study period. RESULTS: Data from 278 centres and 12,835 consecutive colonoscopies were evaluated. Centres were uniformly distributed throughout Italy - north, centre and south - as was their organizational complexity and workload. Overall, adequate facilities (i.e. cleaning area for disinfection/reprocessing, equipped recovery room), and safety equipment (i.e. pulse oximetry, equipment for emergency cardiopulmonary resuscitation) were lacking in a considerable amount of centres, especially in those with a lower degree of organizational complexity. Written informed consent was routinely required in 87% of the centres, but a specific consent for colonoscopy, including detailed information on adverse events, was adopted by 66%. Regular programs for recording some quality indicators (i.e. cecal intubation, quality of bowel cleansing, patients' satisfaction and complications) were implemented in a minority of centres. About 93% of the colonoscopies were performed for diagnostic purpose; screening and surveillance accounted for 13.7% and 25.3% of the indications, respectively. Sedation and/or analgesia was administered in about half of the patients. Overall, colonoscopies were completed to the cecum in 80.7% of cases, and only 22.1% of the centres reported a cecal intubation rate >or=90%; this figure was reported in 33.1% of centres with high-organizational complexity and in 14.4% of outpatient units. The overall incidence of immediate complications was low (2 perforations, 26 bleedings and 32 serious cardiorespiratory complications). CONCLUSIONS: This study documented a wide variation in colonoscopy practice between centres and highlighted problem areas where interventions are needed to improve performance and safety of the examinations.
