BACKGROUND: The prevalence of venous thromboembolism (VTE) has been increasing in China. However, the treatment pattern and economic burden of these patients have not been well-understood.
OBJECTIVE: The objective of this study was to examine the patient characteristics, treatment pattern, anticoagulant monitoring, and economic burden of VTE among hospitalized patients in China.
METHODS: Hospitalizations with a diagnosis of VTE [including deep vein thrombosis (DVT) or pulmonary embolism (PE)] between 1 January 2010 and 30 June 2013 were included. Descriptive analysis was conducted for patients' characteristics, anticoagulant treatment, international normalized ratio (INR) monitoring, and hospitalization cost [in 2013 Chinese yuan (Y) and US dollars (US$)]. Multivariate regressions were performed to assess factors associated with oral anticoagulant use and total costs of inpatient care.
RESULTS: A total of 1,047 VTE-related hospitalizations were selected. The sample had a mean age of 62.4 years, with 45.9 % female. About 46.3 % of hospitalizations used heparin only, 35.0 % used warfarin, 0.8 % used rivaroxaban, and 18.0 % did not use anticoagulants. Among hospitalizations where warfarin was used, 90.8 % received at least one INR test and only 30 % had the last INR within the target therapeutic range (2-3) before discharge. The mean (standard deviation) total cost per hospitalization was Y29,114 (43,772) [US$4,757 (7,152)]. PE, VTE as primary diagnosis, female, insurance coverage, anticoagulant treatment, co-morbidities, admission condition, and surgical procedure were significantly associated with inpatient costs.
CONCLUSIONS: Conventional anticoagulants were most commonly used in the study sample. Under-monitoring and suboptimal care may be an issue for patients treated with warfarin. The average total inpatient cost of VTE-related hospitalizations is high.
