Clinical research studyIncidence of Venous Thromboembolism in Patients Hospitalized with Cancer
Section snippets
Data Sources
The number of patients discharged from hospitals with a diagnostic code of various malignancies, pulmonary embolism or deep venous thrombosis from 1979 through 1999 was obtained from the National Hospital Discharge Survey.16 The National Hospital Discharge Survey is based on data abstracted from a national probability sample of discharges from short-stay nonfederal hospitals.16 The National Hospital Discharge Survey from 1979 through 1999 consists of data obtained annually from 181 000 to 307 000
Results
Among patients hospitalized from 1979 through 1999, with any of the 19 categories of malignancies evaluated, 827 000 of 40 787 000 (2.0%) had venous thromboembolism, which was twice the incidence of venous thromboembolism in hospitalized patients who did not have any of these malignancies, 6 854 000 of 662 309 000 (1.0 %). The highest incidence of venous thromboembolism was in patients with carcinoma of the pancreas, 51 000 of 1 176 000 (4.3%) (Table 1). The lowest incidence of venous thromboembolism
Discussion
Among patients hospitalized with cancer in short-stay hospitals in the United States, we report venous thromboembolism in 2.0% and pulmonary embolism in 0.6%. The incidence of venous thromboembolism, pulmonary embolism, and deep venous thrombosis in patients hospitalized with various malignancies was double the rate observed in hospitalized patients who did not have any of these malignancies. The rate of venous thromboembolism varied with various malignancies from 4.3% in patients with
