Abstract:
Objective:To analyze the distribution characteristics and influencing factors of prolonged length in the elderly patients at a tertiary hospital.Methods:Medical records of patients receiving inpatient care at Xiangya Hospital, Central South University in Hunan province during January 1, 2021 and December 31, 2023 were collected.The generalized estimating equation(GEE)model was used to analyze the factors influencing prolonged hospitalization in elderly patients.Results:A total of 144 921 elderly inpatients were included, aged 60 to 104 years, with 84 950 males and 59 971 females.The average length of hospitalization was 7.81 days, with 2 614 patients hospitalized for more than 30 days (1 663 males and 951 females), and the average length of stay for these patients was 44.93 days.Most of the patients with prolonged length were hospitalized for 30 to 40 days, and in the group of aged 60-74 years.Disease categories mainly were related to health conditions, healthcare facility contact, tumors, and circulatory system diseases.The GEE model analysis showed that nosocomial infection [ OR(95% CI): 5.836(4.716-7.221)], age≥90 [ OR(95% CI): 2.415(1.680-3.472)], surgery [ OR(95% CI): 3.543(2.925-4.291)], number of complications>4[ OR(95% CI): 2.378(2.091-2.704)], unplanned hospital readmissions within 31 days [ OR(95% CI): 1.748(1.525-2.004)]were risk factors of prolonged hospitalization; female [ OR(95% CI): 0.901(0.824-0.986)] and no transferred hospitalization [ OR(95% CI): 0.154(0.140-0.169)] were protective factors. Conclusions:Prolonged hospitalization is related to the clinical and social factors.Administration department of the hospital should strengthen the monitoring of these influencing factors, reduce or prevent the occurrence of prolonged length of stay by adopting targeted measures, and further realize rational allocation of medical resources.
