This study demonstrated that family member completed FAM-CAM had acceptable agreement with researchers' delirium assessments. Postoperative delirium symptoms were detected more frequently by family-administered FAM-CAM compared to delirium incidence identified by researcher assessments. Family members identified that some patients experienced delirium symptoms after hospital discharge.
