Objective:
Interest in humanitarian surgery is high among surgical and obstetric residents. The Colorado Humanitarian Surgical Skills Workshop is an annual 2-day course exposing senior residents to surgical techniques essential in low- and middle-income countries but not traditionally taught in US residencies. We evaluated the course's ability to foster resident comfort, knowledge, and competence in these skills.
Design:
The cohort of course participants was studied prospectively. Participants attended didactic sessions followed by skills sessions using cadavers. Sample areas of focus included general surgery (mesh-free hernia repair), orthopedics (powerless external fixation), and neurosurgery (powerless craniotomy). Before and after the course, participants answered a questionnaire assessing confidence with taught skills; took a knowledge-based test composed of multiple choice and open-ended questions; and participated in a manual skills test of tibial external fixation.
Setting:
The Center for Surgical Innovation, University of Colorado School of Medicine.
Participants:
A total of 12 residents (11 general surgical and 1 obstetric) from ten US institutions.
Results:
After the course, participants perceived increased confidence in performing all 27 taught procedures and ability to practice in low- and middle-income countries. In knowledge-based testing, 10 of 12 residents demonstrated improvement on multiple choice questioning and 9 of 12 residents demonstrated improvement on open-ended questioning with structured scoring. In manual skills testing, all external fixator constructs demonstrated objective improvement on structured scoring and subjective improvement on stability assessment.
Conclusions:
For senior residents interested in humanitarian surgery, a combination of skills-focused teaching and manual practice led to self-perceived and objective improvement in relevant surgical knowledge and skills. The Colorado Humanitarian Surgical Skills Workshop represents an effective model for transmitting essential surgical principles and techniques of value in low-resource settings.
