A theoretical framework for developing a health impact assessment implementation model in Ireland

Abstract

Abstract Background A Health Research Board (HRB) four-year research study, which commenced in January 2023, seeks to explore the process of carrying out Health Impact Assessments (HIAs) with a view embedding the approach as normal practice in local and national policy development in Ireland. Methods A theoretical framework has been constructed to develop an HIA implementation model. The framework is based on the all-island Institute of Public Health Ireland's HIA guidance. The theoretical framework will examine factors affecting HIA implementation, using both the Consolidated Framework for Implementation Research (CFIR) and Normalisation Process Theory (NPT). An action research methodological approach will be used to gather data on the experiences that participants will reflect on while doing the HIA. Participants included in the study will be the members of the two HIA Steering Groups created for each HIA (12 participants in each HIA) and policy end-users of the HIA evidence from the city council and government ministries (20 participants for each HIA). Results The theoretical framework will be applied to two HIAs, in order to generate data in creating the HIA implementation model. HIA 1, commencing October 2023, will be conducted on the local government Cork City Development Plan. HIA 2, commencing January 2025, will be carried out on the Irish Government's Climate Action Plan. Preliminary results on the application of the theoretical framework to HIA 1 will be presented, as well as reflections for the planned HIA 2. Conclusions For the first time in Ireland and beyond, a theoretical framework has been developed employing innovative methodological approaches to building a contextualised HIA implementation model. Using action research in assessing the implementation of HIA, with a view to analysing the lived experience of Steering Group members as they conduct the HIAs, and policy end-users, will ensure an enhanced HIA implementation model. Key messages • The development of an innovative theoretical framework for the study of HIA. • The building of HIA capacity in Ireland using the newly revised Institute of Public Health guidance.
