Nurse-led physical health interventions for people with mental illness: an integrative review of international literature

Background: People experiencing mental illness receive physical healthcare from nurses in a variety of settings including acute inpatient, secure extended care, forensic, and community services. While nurse-led clinical practice addressing sub-optimal consumer physical health is salient, a detailed understanding and description of the contribution by nurses to physical health interventions in people experiencing mental illness is not clearly articulated in the literature. Aims: The aim of this integrative review is to describe the state of knowledge on nurse-led physical health intervention for consumers, focusing on nursing roles, nursing assessment, and intervention settings. Methods: A systematic search of six databases using Medical Subject Headings from 2001 and 2022 inclusive was conducted. The Mixed Methods Appraisal Tool (MMAT) was utilised for quality appraisal. Results: Seventy-four studies were identified as “nurse-led”. Interventions were most common among community settings (n = 34, 46%). Nurses performed varied roles, often concurrently, including the collection of 341 physical health outcomes, and multiple roles with 225 distinct nursing actions identified across the included studies. A nurse as lead author was common among the included studies (n = 46, 62%). However, nurses were not always recognised for their efforts or contributions in authorship. Conclusions: There is potential gap in role recognition that should be considered when designing and reporting nurse-led physical health interventions.
