An evaluation of interventions to improve outcomes for hospitalized patients in isolation: A systematic review.

Abstract

Background: Isolation is effective in preventing transmission of infectious disease. However, it has been shown to have negative effects including increased anxiety and poor physical outcomes. Objective(s): To summarize the effects of interventions to improve safety and outcomes for patients in isolation Design: Systematic review (PROSPERO protocol registration - CRD42020222779). Setting(s): Acute hospital Participants: Intervention studies including patients in preventative or protective isolation in a single room. Method(s): MEDLINE, Global Health, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and Excerpta Medica database were searched from 1996-October 2020. Two independent reviewers screened references and assessed risk of bias. One reviewer extracted data and was checked by another. Main outcomes were Quality of Life and mortality. Result(s): We identified 16,698 references and included 6 studies with different study designs. Average age ranged from 4-71 years. Samples sizes were small (range 10-49 participants) apart from one non-randomized controlled trial including >600 participants. Interventions were music therapy (n = 3), psychological counseling (n = 2) and exercise training (n = 1). One study reporting on Quality of Life and found no change after exercise. None of the studies reported on mortality. Due to heterogeneous results no meta-analyses were performed. Conclusion(s): There is a lack of high-quality evidence for effective comprehensive interventions to manage adverse effects associated with isolation. Future studies should investigate the effect of multi-component interventions using rigorous methods to improve outcomes for hospitalized isolated patients.Copyright © 2021 Association for Professionals in Infection Control and Epidemiology, Inc.
