Effects of nonpharmacological interventions on sleep improvement and delirium prevention in critically ill patients: A systematic review and meta-analysis.

OBJECTIVE: Sleep disturbance and delirium are common problems experienced by critically ill patients in the intensive care unit (ICU). These interrelated issues increase the length of stay in the ICU but might also negatively affect long-term health outcomes. The objective of this study was to identify the nonpharmacological interventions provided to improve sleep or prevent delirium in ICU patients or both and integrate their effect sizes. REVIEW METHODS: This study was a registered systematic review and meta-analysis. We searched MEDLINE, CINAHL, EMBASE, Web of Science, and Cochrane Library from their inception until December 2021. We included randomised controlled trials and nonrandomised controlled trials-(RCT) that provided nonpharmacological interventions and reported sleep or delirium as outcome variables. Studies not published in English or whose full text was not available were excluded. The quality of the evidence was assessed with version 2 of the Cochrane risk-of-bias tool for RCTs and the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I). RESULTS: The systematic review included 118 studies, and the meta-analysis included 100 studies. Overall nonpharmacological interventions had significant effects on subjective sleep quality (standardised mean difference = 0.30, 95% confidence interval [CI] = 0.05 to 0.56), delirium incidence (odds ratio = 0.62, 95% CI = 0.53 to 0.73), and delirium duration (standardised mean difference = -0.68, 95% CI = -0.93 to -0.43). In individual interventions, aromatherapy, music, and massage effectively improved sleep. Exercise, family participation, information giving, cognitive stimulation, bright light therapy, architectural intervention, and bundles/protocols effectively reduced delirium. Light/noise blocking was the only intervention that ensured both sleep improvement and delirium prevention. CONCLUSIONS: Our results suggest nonpharmacological interventions improve sleep and prevent delirium in ICU patients. We recommend that ICU nurses use nonpharmacological interventions that promote person-environment compatibility in their clinical practice. The results of our review can guide nurses in adopting interventions related to sleep and delirium. PROSPERO REFERENCE NUMBER: CRD42021230815.

Development of a comprehensive model for the role of the rapid response team nurse.

OBJECTIVE: To develop a comprehensive model of the role of the rapid response team nurse. DESIGN: Using an experience-based co-design approach, qualitative data concerning the categories and components of the role of the rapid response team nurse were generated via workshops and one-on-one interviews with service users and providers. The appropriateness of the comprehensive model was evaluated through an online survey. SETTING: Forty-six tertiary hospitals across South Korea. A total of 114 rapid response team service providers and users were recruited using convenience sampling. FINDINGS: The comprehensive model included the requirements, facilitating factors, barriers, and outcomes as well as the roles and tasks of rapid response team nurses. The key roles in the final model were found to be: 1) Screening of patients with acute exacerbation, 2) Professional support for emergencies, 3) Education for service users, 4) Consultation for high-risk patient care, 5) Support for patient and family decision-making, 6) Coordination between departments, and 7) Management of the rapid response team. These roles contain 57 specific tasks. Rapid response team professionals finalised the model by evaluating the appropriateness of its components. CONCLUSION: An experience-based co-design approach was used to develop a comprehensive model that reflects the insights and needs of rapid response team service users and providers. We recommend that the model be validated and supplemented by data from different institutions and countries.
