EP-373 Appropriate requesting of tumor marker, CEA, at a district hospital in Ireland: An audit cycle to improve practice

Abstract

Abstract Aims Tumor markers play an important role in oncology and the appropriate requesting of tumor marker tests are facilitated by national and international guidelines, inappropriate use increases both the laboratory workload and overall cost of management. Our aim was to assess our practice against the ACBI (Association of Clinical Biochemists in Ireland) guidelines for carcinoembryonic antigen (CEA) and conduct teaching sessions to improve practice. Methods 1st cycle: All carcinoembryonic antigen (CEA) tests ordered in the hospital between the 1st to 31st of October 2020 were obtained through the HSE Online Lab Web Inquiry System, files were then reviewed for indications. Results from the initial audit were presented to the department and two separate teaching sessions were conducted to educate on the guidelines. 2nd cycle: All CEA test ordered from 1st January to 28th February 2021 were obtained, re-audited and results were compared. Results 76% of the tests ordered by General Surgery in the second cycle were appropriately ordered and incorrectly ordered tests decreased from 35.7% to 23.8%. Conclusions Through the process of this audit an improvement was seen in practice of the department. More tests ordered adhered to indications in guidelines.
