Implementation, construct validity, and benefit of a proficiency-based knot-tying and suturing curriculum.

Area of Science:

• Medical Education
• Surgical Skills Training
• Residency Programs

Background:

• Surgical residents require standardized training in fundamental skills.
• Proficiency-based curricula offer a structured approach to skill acquisition.
• Evaluating the feasibility and effectiveness of such curricula in residency is crucial.

Purpose of the Study:

• To assess the feasibility of implementing a proficiency-based knot-tying and suturing curriculum in a residency program.
• To evaluate the construct validity and educational benefits of the curriculum.
• To determine the cost-effectiveness of the implemented training.

Main Methods:

• A 12-week prospective study involving 37 PGY1 residents.
• Residents utilized video tutorials and self-practiced 12 standardized knot-tying and suturing tasks to proficiency.
• Performance was assessed at baseline and posttesting, with questionnaires completed.

Main Results:

• The curriculum was implemented with 376 person-hours and $776 in material costs.
• All residents achieved proficiency within 12 weeks.
• Significant improvements in performance were observed from baseline to posttesting (p < 0.001), supporting construct validity and skill acquisition.

Conclusions:

• A proficiency-based surgical skills curriculum is feasible and cost-effective for residency programs.
• The curriculum provides educational benefits and validates skill acquisition.
• Further evaluation of operating room transferability and broader adoption is recommended.
