Résumé
Blood and blood components are used inappropriately in surgery and non surgery procedures. In medical settings, blood transfusion is important and its appropriate practice requires adequate expertise and knowledge; thus, this study is designed to assess the knowledge level of health care workers regarding appropriate use of blood and blood components in hospitals of Zabol. This is a descriptive study conducted on 122 nurses and health care workers. Data were collected by a questionnaire including 30 questions; they were then analyzed by SPSS version 11 software and Chi-Square. Findings showed that 26.2% of health care workers had a low level, 22.1% a moderate, and 51.6% an acceptable level of knowledge about appropriate use of blood. We did not find any significant correlation between the knowledge level of health care workers and their years in profession, age, gender, university degree, etc. Results strongly emphasized the need for a curriculum to promote knowledge of health care workers regarding blood transfusion because we found a low and moderate level of knowledge in approximately half of the participants
