title: Evaluation of a thromboprophylaxis quality improvement project in a palliative care unit.
abstract: BACKGROUND
  The benefits of anticoagulation treatment for primary prophylaxis in patients with advanced progressive diseases are unclear. Moreover, there are no empirically based guidelines on thromboprophylaxis for palliative care patients.
  
  
  OBJECTIVE
  To prospectively evaluate a quality improvement protocol on the use of thromboprophylaxis on a 36-bed palliative care unit (PCU).
  
  
  METHODS
  A protocol was developed to guide and standardize practice related to venous thromboembolic events (VTE) and anticoagulation medication use on the PCU in patients with a life expectancy of less than six months. Through a prospective audit, data were collected for consecutively admitted patients over a period of four months.
  
  
  RESULTS
  Of the 127 patients admitted to the PCU, 41 (32.3%) were on thromboprophylaxis on admission. All but one of these patients had come from an acute care hospital. Thromboprophylaxis was discontinued in 36 (87.8%) of these patients; one patient went on to develop a VTE. Of the 71 patients admitted without thromboprophylaxis, none of the patients were started on thromboprophylaxis and six went on to develop a VTE.
  
  
  CONCLUSIONS
  In this quality improvement study of patients admitted to a PCU largely for end-of-life care, thromboprophylaxis was discontinued in most patients without a significant increase in the incidence of symptomatic VTE. The validity of recommendations extrapolated from the general hospitalized cancer population supporting routine thromboprophylaxis and applied to these patients can be challenged. A policy that requires thromboprophylaxis in all hospitalized cancer patients may run the risk of indiscriminately including patients who are in the terminal phase of their lives.
