Objective: To increase the consciousness of incident deep venous thrombosis (DVT) in hospitalized patients. Methods: This is a retrospective study of hospitalized patients with DVT in Beijing Shijitan Hospital from 2007 to 2016. Clinical features of DVT patients who were admitted with no DVT were summarized. The demographic and epidemiological characteristics, involved site of veins, department of patients and risk factors were discussed. Results: A total of 5 063 patients were complicated with DVT from 305 922 inpatients who were without DVT at the admission during past 10 years. Among them, 54.36% (2 752/5 063) were men. The age of the patients was (74.1±15.9) years old (range 1-103 years) with 37.78% of them in 80 to 89 age group. The incidence of DVT in the hospital was 1.65%. It increased yearly during the past decade (from 0.50% to 2.74%), and increased with age in patients from 1 to 99 years old (7.32% in 90-99 age group). Totally, 5 204 veins were involved in the patients. Most thrombosis involved inferior vena cava system (96.54%,5 024/5 204), especially deep veins of lower extremity (83.78%,4 360/5 204), some involved portal veins (8.61%,448/5 204) and a little was found in superior venae cava (3.46%, 180/5 204). More DVT patients were in department of internal medicine than those in department of surgery (2.95% vs 0.97%, P<0.01). ICU had the highest rate of DVT among the hospital departments (9.75%). No DVT occurred in department of newborn. Risk factors of DVT were inflammatory diseases (71.54%), age over 75 years old (67.25%), and heart diseases (58.98%). Conclusion: Sensitivity of detection on DVT should be emphasized in hospitalized patients with DVT risk, especially at the department with high incident of DVT.
