Background: Over the last decade, the United States has witnessed an increase in mass casualty incidents (MCIs). The outcome of an MCI depends upon hospital preparedness, yet many hospitals are unfamiliar with their facility MCI procedure. Educational training drills may be one method to improve staff knowledge of policy and procedure.


Objective: This study aimed to improve knowledge gained through educational MCI mini drills of institutional mass casualty policy and procedure in surgery department staff at a level II trauma center.


Methods: A pre-/posttest design was utilized. The hospital implemented MCI mini training drills as a quality improvement project using Plan-Do-Study-Act iterative cycles with prospective data collection. Knowledge scores were measured using a 12-item surgery department MCI policy and procedure questionnaire that was developed by the author and leadership.


Results: A one-way analysis of covariance analysis in participants that mini drilled more than once indicated significant effect on mean cycle score differences among three cycles F(2,21) = 12.96, p = .00. Multiple comparison using Games-Howell indicated the mean score for Cycle 4 (M = 96.15, SD = 6.54) was significantly different from Cycle 3 (M = 59.71, SD = 25.15). Gender, shift, and credentials of participants influenced knowledge improvement.


Conclusion: Implementation of hospital MCI mini drills improved staff knowledge of institutional mass casualty policy and procedure in the surgery department and may be applied to surgery departments with similar policy, procedure, and participant characteristics. Hospital mass casualty response education and preparation is essential to saving lives.
