Few studies exist that measure the quantitative impact of trauma-informed primary care. As a result, health care providers often struggle to answer critical questions, such as: “What patient outcomes need to be measured to know if trauma-informed primary care is working?” In this brief, authors Miguelina Germán, PhD, Dana E. Crawford, PhD, and Kathleen Dumpert, PsyD from Montefiore Medical Group’s Trauma-Informed Care Program propose a measurement model for trauma-informed primary care and suggest potential variables that could be assessed for each major intervention component. This measurement model is based on the experiences of Montefiore Medical Group and other health care organizations that participated in Advancing Trauma-Informed Care, a national initiative led by the Center for Health Care Strategies with support from the Robert Wood Johnson Foundation.
