The evidence base of nurse-led family interventions for improving family outcomes in adult critical care settings: A mixed method systematic review.

Background: The COVID-19 pandemic has exacerbated the consequences of a patient's admission to critical care settings, causing families to face more psychosocial issues than in previous years. Thus, nurses and other clinicians need to keep abreast of interventions that support the families of critical care patients.

Objective: To provide evidence of nurse-led family interventions and their family outcomes in adult critical care settings.

Design: A mixed method systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist.

Data Sources: The search included both a screen of relevant databases (PubMed, Scopus, Cumulative Index of Nursing and Allied Health Literature, and the Cochrane Library) and the screening of citations in relevant articles. Studies published in the English language between January 2010 and October 2020 were considered. The final database searches were performed on 20 October 2020.

Methods: Screening and eligibility assessment were conducted using the Rayyan software. Studies describing the family outcomes of nurse-led interventions in adult critical care settings through either qualitative or quantitative methods were included, i.e., the mixed method synthesis permitted the inclusion of either qualitative or quantitative findings. Article quality was evaluated by three authors using the Joanna Briggs Institute's critical appraisal tools.

Findings: A total of 15 studies - two trials, eight quasi-experimental studies, four qualitative, and one mixed method met the inclusion criteria. The described interventions were organized into five categories: educational/informational; family involvement in care; diary; communication; and bundled interventions. These categories varied in terms of elements, delivery, and family outcomes. Nurse-led interventions that resulted in small to medium improvements in family outcomes included educational interventions with digital storytelling, a bundled approach, informational nursing interventions, and nurse-driven emotional support. The included studies (n = 2) that investigated family rounds in the ICU reported that this approach did not noticeably influence family outcomes.

Conclusion: The differences in the intervention elements, tools, and outcomes evaluated in this review reflect the diversity of family needs, and that numerous interventions have already been developed to promote family health in critical care settings. The evidence suggests that interdisciplinary nurse-led family interventions can improve family outcomes. Tweetable abstract: Interprofessional nurse-led family interventions draw on diverse approaches and improve family outcomes in adult critical care settings.
