Background and study aims: Colonoscopy is increasingly performed by nurse endoscopists. We aimed to assess the endoscopic quality and patient experience of these procedures.

Patients and methods: This prospective multicenter study analyzed 100 consecutive colonoscopies each for 10 trained nurse endoscopists with respect to endoscopic quality and patient experience. Colonoscopies were performed under the supervision of a gastroenterologist, using the techniques and protocols of the participating hospitals. Patient experience was assessed using a questionnaire.

Results: Most nurse endoscopists were female (90 %; median age 43 [range 35 – 49]). Before the start of the study, they had performed a median of 528 colonoscopies (range 208 – 2103). For the 1000 patients, mean age was 56 ± 15 years; 55 % were women; and 96 % were in class I or II according to the American Society of Anesthesiologists’ physical status classification system. Colonoscopies were performed for screening or surveillance in 42 %; for symptomatic indications in 58 % of patients. The unassisted cecal intubation rate was 94 %; the mean withdrawal time was 10 ± 5 minutes. The adenoma detection rate was 26.7 %. In 229 of the colonoscopies (23 %), the nurse endoscopists required assistance from the supervising gastroenterologist. The complication rate was 0.2 %: one perforation and one cardiopulmonary complication. The questionnaire was completed by 734 /1000 patients (73 %) and of these 694 /734 (95 %) were satisfied with the endoscopic procedure. Among the respondents 530 /734 (72 %) had no specific preference for a physician or nurse endoscopist, whereas 113 /734 (15 %) preferred a physician endoscopist, and 91 /734 (12 %) preferred a nurse endoscopist.

Conclusion: The nurse endoscopists performed colonoscopies according to the internationally recognized quality standards and with high patient satisfaction.
