Operative Self-Confidence, Hesitation, and Ability Assessment of Surgical Trainees in Rural Kenya.

BACKGROUND: The education of surgical trainees is ideally designed to produce surgeons with both confidence and competence. This involves the development of autonomy in the operating room. Factors associated with autonomy and entrustment have been studied in high-resource settings. In a resource-limited context, where autonomy is solely at the discretion of faculty, and there are fewer external constraints to restrict it, we hypothesized that assessment of a trainee's performance would be dependent upon reported confidence levels of both faculty and trainees in those trainees' abilities. MATERIALS AND METHODS: At a teaching hospital in rural Kenya, operative experience surveys were administered to eleven general surgery trainees (PGY1-5) and six faculty paired dyads immediately following operative procedures in May 2016 to elicit self-reported assessments of confidence, hesitation, and ability as measured by the Zwisch Scale. We examined factors related to learning and used dyadic structural equation models to understand factors related to the assessment of ability. RESULTS: There were 107 paired surveys among 136 trainees and 130 faculty evaluations. Faculty scrubbed into 76 (72%) cases. In comparison to trainees, faculty were more likely to give a higher average score for confidence (4.08 versus 3.90; P value: 0.005), a lower score for hesitation (2.67 versus 2.84; P value: 0.001), and a lower score for the ability to perform the operation independently (2.73 versus 3.02; P value: 0.01). Faculty and trainee perceptions of hesitation influenced their ability scores. Trainee hesitation (OR 12.1; 1.2-127.6, P = 0.04) predicted whether trainees reported experiencing learning. CONCLUSIONS: Between trainees and faculty at a teaching program in rural Kenya, assessment scores of confidence, hesitation, and ability differ in value but remain fairly correlated. Hesitation is predictive of ability assessment, as well as self-reported learning opportunities. Focus upon identifying when trainees hesitate to proceed with a case may yield important educational opportunities.

Curative Surgery Improves Survival for Colorectal Cancer in Rural Kenya.

BACKGROUND/AIMS: Colorectal cancer (CRC) is increasing in low- and middle-income countries. Surgical care is essential for the treatment. Many patients do not have access to curative surgery for colorectal cancer in rural Kenya. To better understand the impact of surgical care on colorectal cancer in a resource-limited setting, we compared the experience of patients undergoing operations to those who did not. METHODS: All patients with histologically confirmed CRC at Tenwek Hospital from January 1, 1999, to December 31, 2017, were reviewed. Demographic and clinical data were extracted from records when available. The exposure was either curative operation, palliative operation, or no operation. The primary outcome was survival at 5 years, assessed with Cox proportional hazard analysis after propensity-score matching for age, sex, tumor site, time period, and stage. RESULTS: One hundred and sixty-five patients were identified on chart review. Survival information was available for 150 patients with a median follow-up of 319 days. Fifty-two percent had colon cancer and 48% had rectal cancer. At diagnosis, the mean age was 55.4 years (SD: 16.7) and the male to female ratio was 1.1:1. Thirty-nine percent underwent curative operations, 25% palliative operations, and 36% no operations. One-year survival was estimated to be 98% for curative surgery, 73% for palliative surgery, and 83% for no surgery (p = 0.0005). On crude analysis, 5-year survival improved with curative operation in comparison to no operation with a hazard ratio of 0.30 (CI: 0.14-0.64) (p = 0.002). After propensity matching, the hazard ratio for curative operation versus no operation remained significant, 0.34 (CI: 0.14-0.80) (p = 0.01). CONCLUSIONS: Curative surgery improves survival in our resource-limited environment. Although various factors contribute to the use of surgical treatment, the survival advantage persists after adjusted analysis. Barriers exist for access to prompt surgical evaluation and treatment. Surgical care should be a priority to address the increasing burden of CRC in resource-limited settings.
