Principles of blood transfusion service audit.

Blood transfusion is still an important procedure in modern medical practice despite efforts to avoid it. This is due to it's association with infections especially HIV. It is therefore necessary to have proper quality control of its production, storage and usage [1]. A way of controlling usage is to do regular clinical audit. To effect this, there has to be an agreed standard for appropriate use of blood. The aim of this paper is to briefly highlight the importance of audit, audit procedures and tools i.e. required records, development of audit criteria and audit parameters. Every hospital/blood transfusion center is expected to develop a system of audit that is appropriate to its needs. The suggestions are mainly based on the experience at the Lagos University Teaching Hospital and the Lagos State Blood Transfusion Service.
