Colonoscopy completion rates--are we prepared for a national screening programme?

Colonoscopy is a difficult technique to learn. There are international standards regarding its completion rates. An audit of colonoscopy completion rates was carried out using computerized data in which the compliance with international standards was assessed. Of 909 patients overall crude and adjusted (excluding incompletion due to poor preparation and disease) caecal intubation rates were 88% and 94.1% respectively. Of those who were considered eligible for terminal ileal intubation, the crude and terminal ileal intubation rates were 47.3% and 50.3% respectively. The results indicated completion rated as per recommendations and were adequate for any colon screening programme to be successful.
