Abstract: Objective: To explore the effects of a standardized nursing education for family members on on psychological status of patients and family members, and quality of life of patients undergoing robotic pancreaticoduodenectomy. Methods: A total of 60 cases of patients with pancreatic cancer undergoing robotic pancreaticoduodenectomy and their accompanying family members from Faculty of Hepato-Pancreato-Biliary Surgery of a tertiary grade A hospital in Beijing between December 2019 and December 2020 were enrolled in this study. These participants were evenly assigned to the experimental group or the control group according to the odevity of their admission order number. Patients of both groups received routine care. While the family members of patients in the control group and those in the experimental group were given traditional education and standardized education, respectively. The scores of anxiety and depression, quality of life, incidence of nursing adverse events and postoperative rehabilitation indexes of both groups were compared. Results: The anxiety and depression scores of patients and their family members in the study group were decreased significantly compared with those in the control group (P<0.05). The quality of life score of patients increased significantly in the experimental group compared with those in the control group (P<0.05).
