ABSTRACT
OBJECT IVE To investigate the influential factors of direct economic burden of acute exacerbation of chronic obstructive pulmonary disease （AECOPD）patients in hospital ，and to provide related suggestions to reduce the direct economic burden of hospitalization. METHODS During Dec. 1st，2019-Oct. 31st，2020，the data of 1 923 AECOPD patients admitted into the First Affiliated Hospital of Guangzhou Medical University were collected. The information of demographic sociological characteristics，clinical characteristics and cost characteristics were collected ；descriptive analysis ，single factor regression analysis and multiple linear stepwise regression analysis were adopted to investigate the influential factors of direct economic burden of hospitalization. On the basis of literature review ，relevant suggestions were put forward to reduce the direct economic burden of AECOPD patients in hospital. RESULTS & CONCLUSIONS The median of hospitalization cost of AECOPD patients was 15 621.00 yuan. The multiple linear stepwise analysis regression analysis revealed that the influential factors of direct economic burden of AECOPD patients in descending order （by partial regression coefficient ）were the length of stay （logarithmic conversion value ）， admission to ICU ，surgical treatment ，discharge outcome ，whether to salvage ，the use of respirator ，common complications and smoking history （model F＝572.200，R2＝0.750，P＜0.001）. It is suggested to strengthen comprehensive hospital management and promote multidisciplinary cooperation to reduce hospitalization days ；strictly follow the diagnosis and treatment guidelines and clinical pathways to avoid deterioration of the condition and transfer to ICU treatment ；control indications for surgery to avoid“ask for great treatment with only miner illness ”；do a good job in the publicity and education of disease and smoking cessation ，and improve the self-management ability of patients.
