Abstract Objective To analyze the distribution characteristics and risk factors of prolonged hospital length of stay in dermatosis patients based on generalized estimation equation (GEE).Methods Medical records of patients who were diagnosed with dermatosis from 2015 to 2019 in Guangzhou were collected and the GEE was applied to analyze the critical influencing factors of prolonged length of stay.Results Seven hundred and thirty-five inpatients with extremely long hospital stay in recent 5 years were selected, accounting for 4.80% of all patients included in the analysis. The results of GEE model showed that age (OR=1.322, 95%CI:1.110-1.598), marital status (OR=1.899, 95%CI: 1.476-2.442), medical insurance (OR=0.615, 95%CI: 0.516-0.733), surgery (OR=3.270, 95%CI: 2.727-3.921), nosocomial infection (OR=3.972, 95%CI:2.569-6.142), rehospitalization within one month (OR=2.227, 95%CI: 1.438-3.451) and the use of antibiotics (OR=5.891, 95%CI: 4.791-7.243) were influencing factors of prolonged length of stay.Conclusion The prolonged length of stay is related to clinical and social factors of patients with skin diseases. It is necessary to strengthen the monitoring of the influencing factors of prolonged hospital stay, shorten the average hospital stay by effective management means, and realize the rational allocation of medical resources.
