Nurse-led projects for people experiencing homelessness and other inclusion health groups: a realist evaluation

Nursing service development or innovation projects, even small-scale ones, can be difficult to deliver and evaluate, due to a lack of resources and support. Results can also be difficult to disseminate, limiting transfer of learning. This paper presents findings from a realist evaluation of 10 small projects supported by the Queen's Nursing Institute Homeless and Inclusion Health Programme to deliver innovation in health care for people experiencing homelessness and other marginalised groups. These nurse-led projects were funded by the Queen's Nursing Institute and the Oak Foundation, and were largely successful in achieving outcomes to support the improved health of people experiencing homelessness and other marginalised groups. This realist evaluation explores the factors that contributed to the delivery of positive outcomes. All were impacted by the context and the response (mechanisms) of people experiencing homelessness and staff within these settings. It is hoped that the lessons learned will enable better support for nurse innovation projects in the future.
