AB  - Background: In China, the National Cooperation Project of Prevention and Treatment for Venous Thromboembolism provided valuable information about the epidemiology of PE. So, comprehensive assessment on the incidence and case fatality of PE in hospitalized patients can be made firstly.Methods: Between January 1997 and December 2008, consecutive patients, admitted to the inpatient ward with a diagnosis of suspected PE, were registered from 60 hospitals. The data was collected prospectively including demographic data, types and results of diagnosis methods and prognosis. All of patients were identified with a discharge diagnosis of PE based on the St. Anthony's ICD-9 diagnostic codes.Results: From January 1997 to December 2008, hospitalization data were collect for 18,206 patients diagnosed with PE while there were 16,972,182 discharged patients. The annual incidence increased sharply from 0.03% in 1997 to 0.13% in 2003, then persisted 0.14%. Conversely, the case fatality was decreasing apparently from 25.11% in 1997 to 8.65% in 2008.Conclusion: The actual incidence of PE among the hospitalization patients in China was 0.14%. Evidence suggests that a substantial decline in PE-specific mortality and the annual age-adjusted mortality from PE has been shown as a result of the prevention and treatment of PE.
