Hospitalization costs among Hospital-Acquired Venous Thromboembolism patients in China: a cross-sectional study

Abstract

Abstract Background In this study, we aimed to analyze the hospitalization costs for Hospital-Acquired Venous Thromboembolism(HA-VTE) patients in The First Affiliated Hospital of Chongqing Medical University from January 2019 through December 2021, and to determine the factors associated with hospitalization costs. Methods The information of 519 HA-VTE inpatients was collected from the Electronic Medical Record System of the hospital. Univariate and Linear regression analysis were employed to evaluate the association between hospitalization cost and its related factors. Results A total of 519 patients with HA-VTE were included and analyzed, including 319 patients with DVT, 60 patients with PE, and 68 patients with DVT&PE. the mean length of stay (LoS) of HA-VTE patients was 18.55 ± 19.02 days, and the mean hospital cost was RMB 9,047.57 ± 15,793.04, with a median of RMB 4435.95 (IQR 2760.87,8753.76). For patients with DVT, PE, and DVT&PE, the mean length of stay (LoS) was 18.26 ± 18.71 days, 16.37 ± 15.21 days, and 22.16 ± 23.20 days, respectively, and the mean hospital costs were RMB 6412.08 ± 8827.82, RMB 11423.11 ± 11897.64, and RMB 22105.57 ± 33636.74. As for cost composition analysis, medical service fees in accounted for more than 30% of the hospitalization costs, laboratory and tests and material fees were the second and third largest percentages of the hospitalization costs, respectively. Linear regression analysis showed that Subtype of VTE, LoS, Number of surgery and Payment Type were the key determinants of hospitalization costs for all HA-VTE patients. Conclusions We found that hospitalization costs were significantly higher in patients with DVT & PE than in patients with DVT & PE, and medical service costs were the largest contributor to hospitalization costs, probably because most patients required surgical treatment and more general treatment and care. LoS and subtype of VTE may significantly affect hospitalization costs, and it is recommended to increase the reimbursement rate by medical insurance to prevent complications, Reducing LoS and improving treatability may help to reduce the financial burden of HA-VTE patients in China.
