Our health improvement domain seeks to improve health and wellbeing by improving the socioeconomic, physical and cultural environment, including sustainable development, and by influencing behaviour. This domain is based on the  Healthy Ireland, A Framework for Improved Health and Wellbeing for action to improve the health and wellbeing of the population in Ireland.

• Our health service improvement domain aims to prevent disease and improve health-related outcomes through the design, use and evaluation of effective and efficient healthcare interventions including review of access and pathways of care. Such work will include population health needs assessment, population-focused health service prioritisation, Models of Care, health service implementation, and supporting Integrated Care Programmes for population cohorts and priority populations.

• Our health intelligence domain focuses on using population health surveillance, monitoring trends, and using an evidence-based assessment of policies, programmes, and services to inform health service planning, prioritisation, evaluation and public health action. Public Health will provide collective leadership to build, shape and harness the health information ecosystem to inform and influence decisions for better health at all levels of the health system.
