RESUMO
BACKGROUND: A full set of pre-operative bloods is being done on nearly all trauma patients who are admitted to our institute for surgery-regardless of variables such as patient age, injury sustained, or co-morbidities. This leads to unnecessary bloods being taken. AIMS: The primary aims are (1) to calculate the costs associated with routine pre-operative bloods and (2) to examine how much money could be saved by retrospectively applying a more pragmatic pre-operative bloods policy. METHODS: Trauma theatre cases over a 5-week period were identified with their pre-operative bloods and post-operative transfusions. Labour, material, and processing costs were estimated for each test. An updated pre-operative blood schedule was proposed and applied retrospectively to see if cost savings could be found. RESULTS: Of the 173 orthopaedic procedures performed, 109 (63%) had a group and screen or crossmatch pre-operatively. Fifteen (8.6%) required a post-operative blood transfusion. One hundred and twenty-eight (74%) patients had a full blood count, and renal profile taken pre-operatively. A full set of bloods costs approximately 51.23 to take and process. When the updated pre-operative blood guidelines were retrospectively applied, it would have led to cost savings of 2496 over the 5-week period of this audit, and if extrapolated up to 1 year, could lead to potential annual savings of 25,960. CONCLUSIONS: We have demonstrated that an excessive amount of unnecessary pre-operative bloods have been taken using the current blood schedule. A pragmatic pre-operative blood schedule can lead to significant actual cost savings.
