INTRODUCTION: Patient satisfaction with surgical resident care is not well characterized. This study aimed to understand whether patient evaluation of surgical trainees varies by gender. METHODS: General surgery inpatients were invited to evaluate surgical resident care using a modified Consumer Assessment of Healthcare Providers and Systems Surgical Care Survey (S-CAHPS) after positively identifying photos of surgical trainees. S-CAHPS items were scored by the “top-box” method. Patient evaluations of women vs men were stratified by training level and compared. RESULTS: Ninety-one percent of approached patients participated (n = 324/357, mean age = 62.2 years, 50.3% male). Patient demographics, pain level, and attitudes towards resident care were similar between those evaluating women vs men trainees. Women surgical interns were recognized by patients at a lower rate than men (75% vs 87.2%, p=.01). S-CAHPS scores for women vs men interns were equivalent except for spending sufficient time with the patient (75.6% vs 88.0%, p = 0.02). For senior residents (PGY3-PGY5), there was no difference in patient recognition of women vs men (83.9% vs 85.2%, p = 0.91) or in any S-CAHPS domain (all p > 0.05). CONCLUSION: Gender differences in patient evaluation of surgical trainees are resolved by the senior years, with patients reporting the quality of care of women and men senior surgical residents to be equivalent across all S-CAHPS domains. Future work should aim to understand how to best incorporate patient evaluation into trainee assessment to support development, including a focus on ensuring patients recognize and understand the role of resident care providers regardless of gender.
