Abstract:

INTRODUCTION: The Veterans Health Administration initiated implementation facilitation to integrate intimate partner screening programs in primary care. This study investigates implementation facilitation''s impact on implementation and clinical effectiveness outcomes. STUDY DESIGN: A cluster randomized, stepped-wedge, hybrid-II implementation-effectiveness trial (January 2021-April 2022) was conducted amidst the COVID-19 pandemic. SETTING/PARTICIPANTS: Implementation facilitation was applied at 9 Veterans Health Administration facilities, staged across 2 waves. Participants were all women receiving care at participating primary care clinics 3 months before (pre-implementation facilitation n = 2,272) and 9 months after initiation of implementation facilitation (implementation facilitation n = 5,149). INTERVENTION: Implementation facilitation included an operations-funded external facilitator working for 6 months with a facility-funded internal facilitator from participating clinics. The pre-implementation facilitation period comprised implementation as usual in the Veterans Health Administration. MAIN OUTCOME MEASURES: Primary outcomes were changes in (1) reach of intimate partner violence (IPV) screening programs among eligible women (i.e., those seen within participating clinics during the assessment period; implementation outcome) and (2) disclosure rates among screened women (effectiveness outcome). Secondary outcomes included disclosure rates among all eligible women and post-screening psychosocial service use. Administrative data were analyzed. RESULTS: For primary outcomes, women seen during the implementation facilitation period were nearly 3 times more likely to be screened for IPV than women seen during the pre-implementation facilitation period (OR = 2.70, 95% CI = 2.46, 2.97). Women screened during the implementation facilitation period were not more likely to disclose IPV than those screened during the pre-implementation facilitation period (OR = 1.14, 95% CI = 0.86, 1.51). For secondary outcomes, owing to increased reach of screening during implementation facilitation, women seen during the implementation facilitation period were more likely to disclose IPV than those seen during the pre-implementation facilitation period (OR = 2.09, 95% CI = 1.52, 2.86). Women screened during implementation facilitation were more likely to use post-screening psychosocial services than those screened during pre-implementation facilitation (OR = 1.29, 95% CI = 1.06, 1.57). CONCLUSIONS: Findings indicate that implementation facilitation may be a promising strategy for increasing the reach of IPV screening programs in primary care, thereby increasing IPV detection and strengthening connections to support services among the patient population.
