Introduction: Current epidemiological data for venous thromboembolism (VTE) are derived primarily from Caucasian populations from North America. Little is known for other ethnic groups. This study aimed to describe the incidence, etiologies, and the secular trends of VTE in a Chinese population. Materials and methods: This was an observational study using a hospital VTE registry. Results and conclusions: Between 2004 and 2016, 2214 patients (mean age 66.2 +/- 17.4 years, 57.2% female) were hospitalized for a novel occurrence of venous thromboembolism. Of these, 1444 patients (65.2%) had deep venous thrombosis and 770 patients (34.8%) had pulmonary embolism. Over the 13-year period, there was an increasing trend in the incidence of VTE from 28.1 per 100,000 population per year in 2004 to 48.3 per 100,000 population per year in 2016. There has been a disproportional increase in the incidence of VTE among those aged 75 years or above. Etiologically, the most common cause of VTE was active malignancy with an incidence that increased from 34.8% in 2005 to 60.9% in 2014. In conclusion, the incidence of venous thromboembolism in Hong Kong appears to be lower than that in previous Caucasian series. Nonetheless there has been an increasing incidence of VTE over the past decade, primarily related to aging and malignancy.
