Core surgical training: The influence of time and date on interview outcome

Core Surgical Training has become increasingly competitive over the last 5 years with the competition ratio reaching 4.16 in 2021 compared to 2.31 in 2015. This is thought to be due to two key factors: a large yearly increase in the number of applicants and an unchanging number of jobs. Steps are taken by HEE to ensure the process is as standardised and fair as possible. Interview date and time selection remains the only aspect of the process that candidates currently control. We aim to explore whether time and date of an interview has any impact on interview scores within CST.

This study is a national, retrospective cohort study. A freedom of information act request was submitted to HEE to acquire anonymised interview scores and date/time of interview for all CST interviews conducted for the 2022-2023 cohort.

Across the two-week period whereby interviews were held 1264 interviews were undertaken. Candidates with morning interviews had a mean score of 111 (±16) and candidates in the afternoon had a mean score of 108 (±18.5) (p = 0.023). Candidates interviewing in week 1 had a mean score of 107 (±18) and candidates interviewing in week 2 had a mean score of 112 (±16.4) (p < 0.001).

A small difference in score has a significant impact for candidates with their geographical location, specialty choice or event enrolment in the core training programme potentially impacted. It is therefore imperative that these findings receive further evaluation going forward to ensure the process is fair and robust for all participants.
