How can family members of patients in the intensive care unit be supported? A systematic review of qualitative reviews, meta-synthesis, and novel recommendations for nursing care.

Background: Families are an important part of the intensive care unit (ICU) team. Being a family member in the ICU can be distressing due to interacting factors, such as the critical condition of the patient, the responsibility of acting as the patient's advocate, and partaking in decision-making related to treatment. Nurses need to be aware of the family's well-being throughout the patient's ICU stay. Objective: To synthesize reviews of family members' experiences and needs during patients' ICU admission and develop recommendations to support nurses in strengthening their relationships with families. Design: Systematic review of qualitative and mixed method reviews. Data sources: Extensive searches without time limits identified systematic reviews published until June 27, 2024 in CINAHL, PubMed, Scopus, and Web of Science. Reviews were eligible if they provided knowledge required to inform high-quality on-site family care during the patient's ICU admission. Review methods: Quality appraisal adhered to the Joanna Briggs Institute checklist for systematic reviews and research syntheses. Themes were generated by integrating review results and narratively summarizing the main contents. Finally, findings were translated into clinical practice recommendations by using the four-component GRADE-CERQual assessment (low to high recommendation grades). Recommendations were backtracked to primary research studies for validation. All recommendations were critically reflected upon with an expert panel of ICU nurses. Results: The nine included reviews were built on 124 original studies published between 1995 and 2021. One central theme, "Emotional limbo and extreme moments", mirrored the core of families' experiences characterized by waiting time, i.e., for the patient to get better or worse, and overwhelming emotions and confusion brought about by the patient's critical illness. Three sub-themes reflected actions to counterbalance emotional challenges: a) Responding to family members' existential needs, b) Establishing optimal grounds for reciprocal communication, and c) Enhancing a humanizing approach and atmosphere in the ICU. The meta-synthesis resulted in 11 aggregated recommendations. The findings highlighted that nurses should proactively address emotional issues to help preserve families' ability to keep going, allow families to be present and function as a part of the team, and inform families of the patient's situation and how they can practically help. Conclusions: Nurses should use multiple adjustable approaches to alleviate family's burden during an ICU stay. Findings help nurses to prioritize care and make physical and emotional space for family caregivers. Results emphasize the need to facilitate the agency of family caregivers and reinforce their strengths through nurse-family dialogues. Tweetable abstract: Novel recommendations to enhance nursing care of family members to patients admitted to the Intensive Care Unit.
