Background:
It is expected that graduating general surgery residents be confident in performing common abdominal wall hernia repairs. The objective of our study was to assess the confidence of senior surgical residents in these procedures and to identify factors that correlate with confidence.
Methods:
We performed a cross-sectional survey of PGY-4 and PGY-5 general surgery residents at ACGME-accredited programs in the United States in the spring of 2019. Respondents rated their confidence level in 12 hernia procedures on a Likert scale from 1 (not confident) to 5 (extremely confident). Respondents were classified as "Not Confident" (Not Confident, Minimally Confident, Neutral responses) or "Confident" (Confident, Extremely Confident responses). Resident characteristics, program characteristics, and operative experience were collected, and we calculated the area under the curve to screen which factors discriminated between those confident versus not. Multivariable Poisson regression was used to estimate prevalence ratios (PR) and 95% confidence intervals (CI) to identify which factors were most predictive.
Results:
A total of 93 surveys were completed. Respondents reported low confidence rates (25%-60%) in the following hernia repairs: minimally invasive (MIS) inguinal, femoral, tissue (nonmesh) inguinal, pediatric inguinal, and abdominal wall reconstruction. High confidence rates (>80%) were reported for open umbilical, open ventral, and MIS ventral hernia repairs. For MIS inguinal hernia repair, PGY-5 level was associated with a twofold increase in confidence (PR = 2.01; 95% CI = 1.34-3.30), and dedicated research years were associated with low confidence (PR = 0.67; 95% CI = 0.43-1.04). In general, higher operative volumes of a specific repair were associated with increased confidence in that procedure.
Conclusions:
Senior surgical residents reported low confidence in performing a variety of essential hernia repairs (particularly MIS inguinal, femoral, and tissue inguinal). Addressing factors associated with low confidence may help increase resident confidence.
