Family participation in intensive care unit (ICU) multidisciplinary rounds (MDR) is a recommended clinical practice guideline that recognizes the importance of supporting core elements of patient-and family-centered care including dignity and respect, information sharing, participation, and collaboration (Institute for Patient-and Family-Centered Care [IPFCC], 2021). Neonatal and pediatric critical care settings embraced family participation in multidisciplinary rounds in past decades, with adoption in adult ICU settings occurring more recently. Few studies have examined family participation in MDR in adult critical care settings. The purpose of this study was to examine and explore the experiences and perspectives of critically ill individuals’ family members with regards to MDR in the context of an adult ICU. Using a qualitative interpretive description approach, seven family members who participated in multidisciplinary rounds in an adult ICU in an urban western Canadian hospital were interviewed about their experiences and perceptions. Three themes were identified: (i) learning how to participate in MDR; (ii) feeling included and part of the team in MDR; and (iii) in the know -- the benefits of sharing information in MDR. Recommendations for practice include ensuring families are provided with information about the structure and processes of MDR and the types of questions to ask prior to attendance through the provision of written materials. Recommendations for research include future studies on the impact of MDR participation on patient, family, and team outcomes and the differences between in-person and virtual participation in MDR.
