Abstract: Objective To explore the methodology and significance of prospective auditing and evaluation system for blood transfusion and establish an effective system,which can feedback intervene to promote quality of clinical transfusion. Methods First we develop the process of blood transfusion prospective auditing and evaluation. It demands for enhanced medical record and better statistics for optimal auditing and evaluation by transfusion physician. Results Transfusion in Medical treatment should be auditd with laboratory indicators and medical records. Perioperative transfusion risk can be assessed by a scoring system for each disease. For example,the patients with lumbar spinal stenosis scored over 4 points have a ratio of >50% for perioperative transfusion. These Methods could obviously reduce the volume of blood requested and used. Post-transfusion evaluation should be automatically evaluated by transfusion management information system,and then the inappropriate case would be re-evaluated by transfusion physician according to the medical records. Conclusion Clinical data and records are useful tools for prospective auditing and evaluation. Individual prospective auditing and evaluation by transfusion physician can meet the requirements of evidence-based medicine and precision medicine.
