Intimate partner violence: protocol of a quasi-experimental study to increase primary care professionals ability to identify exposed individuals

Introduction The overall aim of the present project is to increase healthcare professionals' ability to ask about exposure and to identify individuals exposed to intimate partner violence (IPV). The project will evaluate the effects of three different interventions that can be assumed to increase healthcare professionals' ability to ask and identify individuals who have been or are exposed to IPV.

Methods This project has a quasi-experimental design. After a 2-month baseline period, participating care units (primary health centres, maternal health clinics and youth guidance clinics) will be assigned to one of three interventions to potentially increase the ability to enquire and identify patient exposure to IPV: (1) healthcare professionals' use of a standardised questionnaire about exposure to IPV in patient meetings, (2) training through the use of a virtual patient case tailored to health professionals and (3) a combination of (1) and (2) earlier.

Preintervention (baseline) and postintervention measurements of the health professionals' enquiry and identification of patients exposed to IPV will be used to explore the effect of the interventions. Focus group interviews with the participating health professionals will be used as a qualitative method, applying thematic analysis, to explore which intervention they perceive as most effective in increasing their ability to identify victims of IPV.

Analysis Data analysis will focus on a comparison of pre- and post-measurements regarding the number of patients asked about and identified patients in each intervention arm that have been or are exposed to IPV. Measurements will be carried out per care unit at the group level.

Qualitative data from focus group interviews will be analysed using thematic analysis. Ethics and dissemination All participants will sign a written consent form and the study has been approved by the Swedish Ethical Review Authority (Dnr 2023-03399-01).

The study will be conducted according to good clinical practice and the Declaration of Helsinki. The results of this study will increase knowledge about how identification of violence in close relationships can be improved in the clinical setting through publications in peer-reviewed journals and presentations at national and international scientific conferences.

Study status Recruiting since May 2024. Expected trial termination December 2026.
