Preliminary Data on Trauma Knowledge, Confidence, and Stress During Navy Trauma Training

The Navy Trauma Training Center (NTTC) is a military-civilian partnership that provides advanced trauma training for application across the range of military operations while exposing military medical personnel to high-volume and high-acuity trauma. Few published data evaluate the outcomes of military-civilian partnerships, including NTTC. The purpose of this study is to evaluate the knowledge, confidence, and stress of NTTC participants before, at mid-point, and after completion of the program. Participants include corpsmen (HM), nurses (RNs), physician assistants (PAs), and physicians (MDs).

These are preliminary data from an ongoing prospective, observational study with repeated measures. Included are participants that complete NTTC training. Pre-training measures include a demographic questionnaire, trauma knowledge test, Confidence survey, and the Perceived Stress Scale. These same instruments are completed at mid-training and at the conclusion of the NTTC curriculum. Data were analyzed using paired t-tests and linear mixed models.

The sample was composed of 83 participants (49 HM, 18 RNs, 4 PAs, and 12 MDs. Knowledge and confidence increased from baseline to post-NTTC for each clinical role (P < .05). Stress for all roles was low and stable over time (P > .05).

These preliminary data suggest that, as expected, trauma-related knowledge and confidence increase significantly with training at NTTC. Stress was low and stable over time. These data from a small sample of participants indicate NTTC training is increasing participants' trauma knowledge and confidence to care for trauma casualties. Continued collection of data in the ongoing study will allow us to determine whether these early findings persist in the overall study sample and may help inform the optimal length of training needed.
