Comorbid Illness, Bowel Preparation, and Logistical Constraints Are Key Reasons for Outpatient Colonoscopy Nonattendance

الملخص EN

Background.

Colonoscopy nonattendance is a challenge for outpatient clinics globally.

Absenteeism results in a potential delay in disease diagnosis and loss of hospital resources.

This study aims to determine reasons for colonoscopy nonattendance from a Canadian perspective.

Design.

Demographic data, reasons for nonattendance, and patient suggestions for improving compliance were elicited from 49 out of 144 eligible study participants via telephone questionnaire.

The 49 nonattenders were compared to age and sex matched controls for several potential contributing factors.

Results.

Nonattendance rates were significantly higher in winter months; the OR of nonattendance was 5.2 (95% CI, 1.6 to 17.0, p < 0.001 ) in winter versus other months.

Being married was positively associated with attendance.

There was no significant association between nonattendance and any of the other variables examined.

The top 3 reasons for nonattendance were being too unwell to attend the procedure, being unable to complete bowel preparation, or experiencing logistical challenges.

Conclusions.

Colonoscopy attendance rates appear to vary significantly by season and it may be beneficial to book more colonoscopies in the summer or overbook in the winter.

Targets for intervention include more tailored teaching sessions, reminders, taxi chits, and developing a hospital specific colonoscopy video regarding procedure and bowel preparation requirements.
