Communication intervention for families in adult intensive care units during COVID-19 pandemic: A systematic review

Background: Restrictions on ICU family visitation during COVID-19 pandemic posed communication challenges for families, patients, and healthcare teams. Diverse approaches were used to overcome communication barriers. As ICUs begin to reinstate family visitation, it is timely to review the lessons learned from these interventions during the pandemic. Objectives: To identify and evaluate content and qualities of the studies that describe communication interventions for families of adult ICU patients during the COVID-19 pandemic. Methods: Following the PRISMA guidelines, we searched PubMed, Embase, CINAHL, and Web of Science for studies that (1) involved communication intervention for families in adult ICU settings, (2) were published between January 2020 and September 2022, and (3) were published in English. We excluded studies that were not from peer-reviewed journal articles or in English. Results: Of 2,628 articles initially identified, we reviewed the 23 selected studies (20 non-experimental and 3 experimental studies). Most of the studies were published in 2022 (n n =14, 60.9%) and conducted in Europe (n n = 13, 56.5 %). Various communication methods (e.g., video calls, telephone, applications) were used to provide information, emotional support, and virtual access to patients and their families. Video calls were the most frequently used intervention. Many interventions included healthcare teams providing updates on the patient's condition or treatment to the family. Conclusions: The COVID-19 pandemic prompted the adoption of diverse communication approaches for families in ICU settings, despite many limitations, including technical challenges. Insights gained from this experience will help expedite flexibility and diversity in designing communication interventions for ICU family members.
