Background and study aims Addition of a reminder program to conventional indications improves colonoscopy. The aim of this study was to evaluate the effectiveness of a short telephone call reminder (STCR) on a patient’s first colonoscopy.

Patients and methods One day before colonoscopy, we made a STCR of < 10 minutes to 141 randomly selected patients of 258 recruited. The STCRs informed patients about the procedure date, indications for taking laxatives, and dietetic requirements. Questions were clarified only when patients asked directly. We evaluated bowel preparation, quality indicators, and patient satisfaction. Data were expressed as mean ± SD and percentages. Statistical differences were evaluated by Student’s t and Chi squared tests; alpha = 0.05. All authors had access to the study data and reviewed and approved the final manuscript.

Results The STCR group had better bowel preparation which was demonstrated by higher completion frequency (97.16 % vs. 82.05 %), in less time (4.52 ± 3.06 vs. 5.38 ± 3.03 hours) intake of laxative, and higher Boston’s scale (7.66 ± 2.42 vs. 5.2 ± 1.65). Quality indicators of colonoscopy were better in patients that received a STCR [cecal intubation rate: 100.00 % vs. 87.18 %; polyp detection: 42.55 % vs. 9.4 %; and cecal arrival time (min): 12.09 ± 3.62 vs. 15.09 ± 5.02]. STCR patients were more satisfied (97.87 % vs. 55.56 %) and would repeat colonoscopy (21.99 % vs. 11.11 %).

Conclusions A simple additional step such as a STCR improves quality of bowel preparation, quality indicators, and satisfaction of patients undergoing their first colonoscopy. Clinical trial registry in Mexico City General Hospital: DI/16/107/3/108.
