Implementing a trauma-informed system of care: An analysis of learning collaborative outcomes

Trauma exposure can negatively impact health. Trauma-informed care implementation within health care systems may improve the identification and treatment of trauma-related illness on a population health level. The current study investigated outcomes of a multiagency implementation of trauma-informed care for Medicaid-enrolled adults and children in 23 rural Pennsylvania (United States) counties. Changes in trauma symptom screening, the number of staff trained in trauma-informed care, and clinician confidence in using trauma-informed care were assessed in participating treatment agencies (N = 22) over the course of a 15-month trauma-informed care learning collaborative (TLC). Data included monthly agency-reported screening, training, and confidence outcomes, which were analyzed using repeated-measures analyses of variance. Trauma symptom screening rates improved from 41.1% (SD = 43.0%) to 93.3% (SD = 12.0), p < .001; eta(2)(p) = .30. The average number of cumulative staff members trained in trauma-informed care per agency increased from 24.43 (SD = 42.22) to 140.00 (SD = 150.87), p < .001, Kendall's W = .09. The percentage of agencies that reported high confidence in delivering trauma-informed care increased from 15.8% (SD = 15.5%) to 80.5% (SD = 17.7%), p < .001; eta(2)(p) = .45. Pairwise comparisons revealed both screening rates and confidence ratings reached significant improvement in Month 11 of the TLC, suggesting that these processes may be related. A total of 2,935 staff members were trained during the TLC. The immediate impact of system-level implementation of trauma-informed care was evident for agency processes and staff confidence, with support provided by multiple stakeholders.
