Patient‐ and family‐centered care in adult <scp>ICU</scp> (<scp>FAM</scp>–<scp>ICU</scp>): A protocol for a feasibility study

This study will assess the feasibility and acceptability when implementing the FAM-ICU intervention and the feasibility of conducting a main trial to investigate its effectiveness on delirium in patients and the mental health of patients and family members. The data from the feasibility study will be used to guide sample size calculations, trial design, and final data collection methods for a subsequent stepped-wedge randomized controlled trial.
