Transfusion premedication practices among pediatric health care practitioners in Canada: results of a national survey.

ABSTRACT

BACKGROUND: Although not supported by strong evidence, premedication (pretransfusion medication) is commonly prescribed to patients who have had a transfusion reaction. The research questions were 1) What are Canadian pediatric practitioners' views and practices regarding premedication and 2) what are barriers to reducing premedication overuse in pediatrics? STUDY DESIGN AND METHODS: An online survey targeted hematology/oncology, emergency medicine, general surgery, intensive care, and cardiac intensive care practitioners in all 16 Canadian pediatric tertiary hospitals. The survey included four sections demographic, clinical, future directions, and organizational questions. RESULTS: Fifty-five individuals from 15 of 16 pediatric tertiary care sites completed the survey 53 physicians and two nurse practitioners. More than half of the respondents (55%; 30/55) were pediatric hematology/oncology providers, and 35% (19/55) were directors of their respective divisions. Eighty-seven percent of respondents estimated that they premedicate up to 25% of red blood cell (RBC) transfusions, and 13% premedicate 26% to 50% RBC transfusions. Proportions were similar for platelet transfusions. Most respondents reported that trainees are involved in transfusion and premedication order decisions. Seven percent believe that their hospital does not use leukoreduction and 27% are not sure. Sixty-five percent of respondents were not aware of a clinical practice guideline or a standard order set (SOS) at their institution 51% are interested in having both available. Factors influencing the decision to premedicate and barriers to change were identified. CONCLUSION: Premedication practices are variable in Canadian pediatric academic hospitals. Evidence-based premedication clinical practice guidelines and SOS could be explored as a way to standardize practices. There were perceived educational and institutional barriers to practice change.
