Poster Abstract
To audit the documentation and efficacy of ultrasound-guided soft tissue biopsy.

100% compliance documenting needle gauge, number of passes, pathology result. All cases should have an image with needle demonstrating the biopsy site. At least 90% of the biopsies should be adequate for pathological diagnosis.

A retrospective audit on ultrasound-guided soft tissue biopsy performed in our center from May 2016 to December 201.. The radiology reports, images and the sarcoma MDT entries on Computerised Radiology Information System were reviewed. Results were compared with previous-audit that was carried out for the procedures performed from December 2015 to May 2016

115 ultrasound-guided biopsies were included in the current audit and 50 in the first cycle. There was no statistical significant difference between the first and second audit cycle in documentation of needle gauge and number of passes, and obtaining sonographic images with needle demonstrating the biopsy site (96% vs. 93%, p=0.31; 100% vs. 96%, p=0.32; 82% vs. 89%, p=0.25; respectively). 92% had documented pathology results on the MDT entries.

Of the 165 cases, 16gauge needle was used in 72% and 18gauge in 20%. Two passes were carried out in 52% of the cases, three passes in 39% and only 3% with four passes. 96% of the biopsy sample were sufficient for pathological analysis and in 95% were diagnostic in determining benign/malignant tumours.

Ultrasound-guided soft tissue biopsy has a high diagnostic yield. There was good documentation rate although 100% compliance was not achieved.
