Self-rated readiness for performance of needle decompression in combat lifesaver training.

BACKGROUND

The Combat Lifesaver course taught to nonmedical personnel includes instruction on performing needle thoracostomy to decompress tension pneumothorax, the second leading cause of preventable combat death. Although the Tactical Combat Casualty Care curriculum is pushed to the lowest level of battlefield first responders, the instruction of this advanced procedure is routinely limited to a verbal block of instruction with a standardized presentation.

OBJECTIVE

The purpose of this study was to assess the confidence of nonmedical personnel in their preparation to perform a needle thoracostomy before Combat Lifesaver training, after verbal instruction on the procedure, manikin training, and practice on a human cadaver.

METHODS

Confidence was assessed by Likert scale surveys, as well as free response remarks collected before and after training.

RESULTS

Self-rated preparedness scores improved significantly with each level of training. Maximal improvements followed cadaver training, from a mean score of 2.31/5 before instruction to 4.75/5 following cadaver training (matched pairs t test: p < 0.005).

CONCLUSIONS

Cadaver training provided the largest single educational confidence boost for needle decompression skills, and is an effective method of enhancing confidence in needle decompression.
