Quality indicators and patient satisfaction in colonoscopy

Colonoscopy is the diagnostic/therapeutic confirmation test for colorectal cancer. The monitoring of the experience of people who have undergone the test is interesting to improve the quality of the colonoscopy. The aim of the project was to study factors affecting patients' experience and their relationship with the quality indicators of the Clinical Practice Guidelines.

An observational cross-sectional study was conducted, including quality and experience indicators (adapted mGHAA-9 questionnaire and clinical history) in a sample of 432 participants aged between 40- and 75-years-old who had undergone a colonoscopy in 2015. Univariate and multivariate analysis with multiple logistic regression.

Satisfaction was associated in the multivariate analysis with evaluating the waiting time for the colonoscopy as short (OR=3.80) (1.76-10.90, 95% CI),>55-years-old (OR=2.60) (1.19-5.68, 95% CI), rating the experience with the preparation positively (OR=7.34) (3.15-17.09, 95% CI), not reporting pain or discomfort during the procedure (OR=3.71) (1.03-13.40, 95% CI) (P=.006) and being examined in a tertiary hospital (OR=2.81) (1.17-6.72; 95% CI) (P=.020).

The mGHAA-9 questionnaire adapted to Spanish is useful to evaluate patient experience factors. There are aspects to improve in terms of waiting time, colon cleansing, satisfaction with preparation and post-colonoscopy problems. Interventions should be implemented to enhance patient experience and colonoscopy quality.
