Aim: To determine the effects of nurse-coordinated interventions in improving readmissions, cumulative hospital stay, mortality, functional ability and quality of life for frail older adults discharged from hospital.

Design: Systematic review with meta-analysis.

Methods: A systematic search using key search terms of 'frailty', 'geriatric', 'hospital' and 'nurse'. Covidence was used to screen individual studies. Studies were included that addressed frail older adults, incorporated a significant nursing role in the intervention and were implemented during hospital admission with a focus on transition from hospital to home.

Data sources: This review searched MEDLINE (Ovid), CINAHL (EBSCO), PubMed (EBSCO), Scopus, Embase (Ovid) and Cochrane library for studies published between 2000 and September 2023.

Results: Of 7945 abstracts screened, a total 16 randomised controlled trials were identified. The 16 randomised controlled trials had a total of 8795 participants, included in analysis. Due to the heterogeneity of the outcome measures used meta-analysis could only be completed on readmission (n = 13) and mortality (n = 9). All other remaining outcome measures were reported through narrative synthesis. A total of 59 different outcome measure assessments and tools were used between studies. Meta-analysis found statistically significant intervention effect at 1-month readmission only. No other statistically significant effects were found on any other time point or outcome.

Conclusion: Nurse-coordinated interventions have a significant effect on 1-month readmissions for frail older adults discharged from hospital. The positive effect of interventions on other health outcomes within studies were mixed and indistinct, this is attributed to the large heterogeneity between studies and outcome measures.

Relevance to clinical practice: This review should inform policy around transitional care recommendations at local, national and international levels. Nurses, who constitute half of the global health workforce, are ideally situated to provide transitional care interventions. Nurse-coordinated models of care, which identify patient needs and facilitate the continuation of care into the community improve patient outcomes. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Review findings will be useful for key stakeholders, clinicians and researchers to learn more about the essential elements of nurse-coordinated transitional care interventions that are best targeted to meet the needs of frail older adults.

Impact: When frail older adults experience transitions in care, for example discharging from hospital to home, there is an increased risk of adverse events, such as institutionalisation, hospitalisation, disability and death. Nurse-coordinated transitional care models have shown to be a potential solution to support adults with specific chronic diseases, but there is more to be known about the effectiveness of interventions in frail older adults. This review demonstrated the positive impact of nurse-coordinated interventions in improving readmissions for up to 1 month post-discharge, helping to inform future transitional care interventions to better support the needs of frail older adults.
