title: Venous thromboembolism risk assessment and thromboprophylaxis among hospitalized acute medical patients in China--the RAMP study.
abstract: BACKGROUND
  In developed countries, hospitalized patients with acute medical conditions are at significant risk for venous thromboembolism (VTE). Little is known about VTE risk and prophylaxis practices in China.
  
  
  OBJECTIVE
  To determine the VTE risk and the frequency of recommended VTE prophylaxis in hospitalized Chinese patients with acute medical conditions.
  
  
  METHODS
  Multi-center, cross-sectional, observational study.
  
  
  METHODS
  ≥30 years, admitted to an intensive care unit (ICU)/coronary care unit (CCU) for acute medical illness, had ≥1 VTE risk factor/1 disease that predisposes to VTE, and provided informed consent. We used 2004 American College of Chest Physicians (ACCP) evidence-based consensus guidelines to assess VTE risk and the frequency of recommended VTE prophylaxis.
  
  
  RESULTS
  1247 patients from 19 hospitals in 11 cities across 11 provinces of China were enrolled from July 2007 to June 2008. 57.3% patients had >2 VTE risk factors. Only 20.2% received ACCP-recommended VTE prophylaxis (CCU patients: 22.7%, ICU patients: 16.9%, p=0.0117).
  
  
  CONCLUSIONS
  Excluding some patients with VTE risk factors did not allow assessment of the prevalence of VTE risk in the acute hospital-care setting. We could not determine whether the duration of prophylaxis complied with the ACCP recommendations. Our results may not be representative of hospitals in small cities/rural areas in China.
  
  
  CONCLUSIONS
  The prevalence of VTE risk factors in Chinese patients was similar to that in developed countries; however, only a small proportion of eligible patients received the recommended VTE prophylaxis. Our findings highlight the need for dissemination and implementation of appropriate VTE prophylaxis guidelines in China.
