Introduction Directly Observed Polypectomy Skills (DOPyS) is a validated tool used to assess polypectomy skills in the UK. The overall competency for polypectomy is graded on a scale of 1 to 4 and is used to certify trainees for level 1 polypectomy (size < 1 cm) & level 2 polypectomy (size 1–2 cm). Trainees are certified as competent if they achieve grades 3 or 4 for more than 90% of their last 4 consecutive DOPyS. We aimed to analyse time required for a trainee to progress from DOPyS score 1 to 4

Methods Retrospective data from the e-portfolio of 707 (4965 DOPyS) trainees from Jan 2009 to Sept 2015 was examined. A dataset of 24 trainees who had documented DOPyS overall score of 1 (CS1), 2 (CS2), 3 (CS3) and 4 (CS4) was recovered. For the purpose of the analysis only those trainees (n = 8) who started out at CS1 were included. 16 were excluded from analysis as they started at a higher level. Primary outcome was number of days taken by each trainee to reach the competency levels (i.e. CS2, CS3 and CS4). The proportion of trainees reaching each level was examined using Kaplan-Meier analysis to show the proportion reaching this level over time. Time taken for 25%, 50% and 75% of trainees to reach the desired level was calculated.

Results Table shows time taken for 25%, 50% and 75% of trainees to reach each of the levels. The results show 50% reach CS2 after 91 days and CS3 after 112 days. It took 191 days for half of trainees to reach level CS4.

Abstract PTH-116 Table 1

Conclusion 75% of trainees analysed reach an overall competency of 4 in 324 days.

In the UK DOPyS score 3 or 4 are required to start applying for provisional/full certification and in our cohort 75% of trainees analysed achieved it in a time frame of 6 months to a year. Further prospective studies analysing time taken, procedure numbers & associated factors are needed to assess the learning curve for polypectomy & implement changes to improve efficiency in training

Limitation The retrospective data and the small numbers are the limitations of the study
