Assessing implementation and health equity determinants to develop a facilitation plan for varied intensity posttraumatic stress disorder (PTSD) treatments in minority-serving institutions.

Though the implementation of science frameworks has recently been expanded to understand determinants of health equity (Woodward et al., 2021), the application of these frameworks in safety net hospital settings is new. We applied the health equity implementation framework to (a) understand the determinants of implementation and equity and (b) develop an institution-wide implementation facilitation plan for three evidence-based practices (EBPs) for posttraumatic stress disorder. We utilized researcher field notes from clinical case consultation gathered during posttraumatic stress disorder treatment implementation initiatives (cognitive processing therapy, written exposure therapy, brief skills training in affective and interpersonal regulation) at the same safety net hospital (N = 94 meetings total, from 2020 to 2023) to assess determinants of implementation and equity. We developed a qualitative codebook based on the health equity implementation framework to specify determinants and then built an implementation facilitation toolkit for multi-EBP implementation. Similar determinants were found across clinics and EBPs (e.g., provider training gaps and misperceptions about manualized treatments; inefficiencies in identification, triage, and referral pathways; patient engagement barriers related to stigma, literacy, and mistrust) with additional nuance per clinic and EBP. Institution-wide facilitation strategies were then utilized to enhance implementation and equity and focused on enhancing both access and quality of services (e.g., training and consultation, refining referral pathways) and patient engagement (e.g., culturally responsive training, consultation, and treatment delivery). Implementation science has an important role to play in enhancing health equity. Our findings illustrate how pooling determinants across clinics and treatments can help implementation scientists engage with hospital leadership and advocate for system-level implementation facilitation strategies.
