title: Effectiveness of a protocol to improve transfusion practice in knee replacement surgery.
abstract: OBJECTIVE
  The available guidelines on red cell transfusion are not clearly defined and therefore have had only a modest impact on transfusion practice. The aims of this study were to assess the rate of compliance with a transfusion algorithm and its effect on transfusion practice.
  
  
  METHODS
  A prospective observational study was carried out on 101 patients who underwent primary elective total knee replacement surgery.
  
  
  RESULTS
  Only 30% of the patients were transfused. An overall compliance rate of 77% was achieved with the transfusion algorithm.
  
  
  CONCLUSIONS
  A transfusion algorithm, together with staff education, is effective in reducing both the number of patients transfused and inappropriate transfusions.
