In-person versus virtual suturing and knot-tying curricula: Skills training during the COVID-19 era.

Abstract Background The coronavirus disease 2019 restrictions on in-person simulation activities necessitated modifying the traditional boot camp skills curriculum for matriculating PGY1 general surgery residents to a virtual format. This study investigated the relative effectiveness of in-person versus virtual instruction on the development of suturing and knot-tying skills. Methods In all, 55 residents participated in a validated, proficiency-based, preinternship skills curriculum, 26 in 2019 and 29 in 2020. Both groups received an introduction to the curriculum, were given time for practice and offered one-on-one tutoring by faculty by request, and completed a filmed posttest. The 2019 class received in-person instruction during a boot camp at the end of June, while the 2020 class was provided with suture kits and received instruction via Zoom throughout June. The 2 groups were compared by post-test performance, date of task proficiency, and additional coaching required. Results In 2019, 5.7% of the posttest tasks were graded as proficient versus 87% in 2020. The 2020 class outperformed the 2019 class on every metric in every task (P Conclusion Learners who received virtual instruction with access to materials at home gained proficiency in suturing and knot-tying skills earlier and with less coaching. These data demonstrate that the virtual curriculum is effective and an improvement on the previous in-person curriculum.
