Abstract

Background/objective: The aims of this study were to describe in detail the ultrasound (US)-guided procedures in our daily rheumatology practice, to evaluate the feasibility and accuracy of US-guided procedures, and to test the efficacy of our disinfection protocol in preventing infectious complications.

Methods: This was a cross-sectional and monocentric study. Information regarding patients' age, sex, body mass index, rheumatic disease, US pathological findings, aspirated and/or injected anatomical site, US equipment (ie, probe type and frequency), and needle type was consecutively collected for each US-guided procedure in a third-level rheumatology center.

Results: A total of 643 US-guided procedures were performed, with a mean of 5.2 procedures per working-day. In 94.2% of the patients, only one procedure was carried out, whereas in 5.8%, more than one. The mean time was 7 ± 2.5 minutes. Ultrasound-guided procedures were highly accurate (accuracy rate higher than 95%) and safe (adverse events were reported in 0.8%). Our disinfection protocol was effective in preventing infectious complications. Probes with frequency values between 8 to 13 MHz and 20-, 21-, and 22-gauge needles were the most frequently used at shoulder, knee, wrist, elbow, and ankle level. High-frequency linear probes (ranging between 18 and 22 MHz) and 23- and 25-gauge needles were used for injecting small joints of the hands and feet. Convex low-frequency probe (2-7 MHz) and 18- and 20-gauge needles were the most used for performing hip joint aspirations and/or injections.

Conclusions: This study reports useful information for setting up a service providing US-guided procedures in rheumatology and supports the feasibility, accuracy, and safety of US-guided procedures.
