Background: The aim of this study was to investigate whether junior surgical residents had
successfully mastered bladder catheterization. Our hypothesis was that surgical residents would be
overly confident in their abilities and underestimate the potential for case complexity.
Materials and methods: PGY 2–4 surgery residents (n = 44) were given 15 min. to complete
three of four bladder catheterization simulations. Participants reported their mastery by rating
confidence using a 5-point Likert scale. Multiple linear regression analysis was used to test
predictors of procedure performance.
Results: Participants made a total of 228 errors with an average of 5.1 errors (standard deviation
= 2.6) per participant. The most common errors included not maintaining the sterile field (52.0%),
failure to get urine return (20.3%), and inflating the catheter balloon before urine return (8.4%).
Some residents committed the same error more than once. Presimulation confidence ratings
ranged from “1” being not confident to “5” being extremely confident. Average presimulation
confidence was 4.42 (range 1–5, standard deviation = 0.85). Sixteen (36%) residents ranked their
presimulation confidence in problem-solving abilities as “moderately confident” or below,
whereas 28 (64%) were “very confident” or above. The lower the resident’s presimulation
confidence in problem-solving, the more errors they committed during the simulation (beta =
−0.33, t = −2.15, P = −0.04).
