Introduction: A cricothyroidotomy is an emergency procedure
that few emergency medicine residents see or perform during
their training. Therefore, there is a need for low cost, high fidelity
models for training. In this study, we explore a new training model
for cricothyroidotomies (the bleeding CRIC [cost-effective realistic
interactive cricothyroidotomy]) to determine if this new tasktrainer
is non-inferior compared to the current standard of training.
Methods: Authors conducted a randomized control noninferiority
study. There were seventeen residents and medical
students enrolled by convenience sample to partake in the study.
The participants were randomized by block randomization to be
taught how to perform a cricothyroidotomy on either the new
task trainer or the current standard task trainer and then were
asked to perform the procedure on a pig trachea model. Primary
outcome measures were scores on a previously validated objective
assessment tool and secondary outcomes were comfort levels and
realism scores based on pre and post survey results which were
analyzed with ANOVA.
Results: There was found to be no statistically significant difference
between the groups in assessment scores, time to completion, or
comfort levels pre- and post-intervention. There was a statistically
significant difference in that the participants gave higher realism
scores in post-test analysis to the Bleeding CRIC compared to the
SimMan. Both groups demonstrated that they had significantly
improved comfort levels from baseline post-intervention.
Conclusion: Overall, the new task trainer was rated by learners
to feel more realistic than the current standard. This study
demonstrates non-inferiority of the new task trainer and further
studies with larger sample sizes should be conducted to determine
its true efficacy.
