Background:
Surgical educators are increasingly exploring surgical
simulation and other nonclinical teaching adjuncts in the education of trainees.
The simulators range from purpose-built machines to inexpensive smartphone or
tablet-based applications (apps). This study evaluates a free surgery module
from one such app, Touch Surgery, in an effort to evaluate its validity and
usefulness in training for hand surgery procedures across varied levels of
surgical experience.
Methods:
Participants were divided into 3
cohorts: fellowship-trained hand surgeons, orthopedic surgery residents, and
medical students. Participants were trained in the use of the Touch Surgery app.
Each participant completed the Carpal Tunnel Release module 3 times, and
participants’ score was recorded for each trial. Participants also completed a
customized Likert survey regarding their opinions on the usefulness and accuracy
of the app. Statistical analysis using a 2-tailed
t
test and
analysis of variance was performed to evaluate for performance within and
between cohorts.
Results:
All cohorts performed better on average
with each subsequent simulation attempt. For all attempts, the experts
outperformed the novice and intermediate participants, while the intermediate
cohort outperformed the novice cohort. Novice users consistently gave the app
better scores for usefulness as a training tool, and demonstrated more
willingness to use the product.
Conclusions:
The study confirms app
validity and usefulness by demonstrating that every cohort’s simulator
performance improved with consecutive use, and participants with higher levels
of training performed better. Also, user confidence in this app’s veracity and
utility increased with lower levels of training experience.
