title: Venous thromboembolism prophylaxis in acutely ill hospitalized medical patients. A retrospective multicenter study.
abstract: OBJECTIVE
  To analyze the incidence of VTE in hospitalized medical patients and prophylaxis applied in accordance with the 8th ACCP guidelines and the National PRETEMED guide for thromboprophylaxis.
  
  
  METHODS
  Discharge lists were reviewed to select the first consecutive 20 patients, aged ≥ 40 years and admitted ≥ 4 days to the Internal Medicine Departments of 79 Spanish hospitals. Exclusion criteria were: admission for diagnostic procedures, VTE or surgical illness, or care during hospitalization provided by the local investigator.
  
  
  RESULTS
  From September 2011 to July 2012, 2845 discharge reports were evaluated and 1623 were considered eligible for the study. Overall 930 (57.3%) patients of this group were at risk of VTE according to the ACCP guidelines, 759 (81.6%) received VTE prophylaxis (mechanical or pharmacological) and 159 (17.1%) had at least one risk factor that might contraindicate anticoagulant use. The proportion of patients at VTE risk according to the ACCP and National PRETEMED guidelines with no risk factors of bleeding that did not receive prophylaxis was 16.3% and 17.2%, respectively. During hospitalization, there were 14 (0.9%) episodes of symptomatic VTE, 12 (86%) of which occurred in patients receiving prophylaxis. VTE rate was 1.3% among patients with VTE risk that received prophylaxis and 3.5% in patients that also had one risk factor that might contraindicate anticoagulant use.
  
  
  CONCLUSIONS
  In a setting characterized by high thromboprophylaxis compliance most of the episodes occurred in patients receiving pharmacological prophylaxis. Patients with combined VTE and bleeding risk factors showed the highest rate of both symptomatic VTE and prophylaxis failure.
