In contrast with community nursing services in the UK and other parts of the world, the public health nursing service in the Republic of Ireland operates as a generalist service, providing both public health and wellbeing services in addition to clinical nursing services to a wide range of patient groups. While much discussion has taken place over the years about the benefits and challenges of a generalist service, little consensus has emerged about whether the current generalist approach should be maintained or whether a more specialised approach is required. This article presents key findings from an evaluation, using research methods, of a community nursing service that was restructured from a generalist, geographically based service, to a more specialist team-based model. The findings across multiple stakeholders show a number of positive effects in the areas of quality, safety, risk, governance, active caseload management, and finances. Some challenges were also identified, particularly with respect to continuity of services, loss of expertise, role of the team leader, and engagement in population-based activities.
