ABSTRACT

Introduction: ultrasound-guided interventional procedures are a rapidly expanding tool in the field of Physical Medicine and Rehabilitation (PM&R). We implemented a 12-month pilot training program for residents to evaluate its institutional feasibility, educational impact, and safety profile. Objectives: 1) to describe the characteristics of the training program. 2) To detail the technical diversity of the procedures (number, type, regions, and substances). 3) To report patient satisfaction. 4) To evaluate the development of the residents’ technical skills. 5) To determine the feasibility of offering this training based on the quality and safety results at our institution. Material and methods: a supervised longitudinal training model was implemented during outpatient consultations. Competency development was assessed using a 60-point scale (measuring transducer selection, target identification, needle visualization, and accuracy). Two residents (n = 2) with no prior technical experience were monitored for 600 hours of theoretical and practical instruction. Results: residents performed 551 therapeutic procedures, including infiltrations (intra-articular and peritendinous), aspirations, and hydrodissections of peripheral nerves. The most frequently treated areas were the shoulder (22.7%) and knee (18.3%). Technical skills showed significant improvement, increasing from a baseline mean of 18/60 to a mastery level of 56/60. Subjective assessment by a single observer showed a significant increase in skills after exceeding the 300-hour threshold of supervised practice. No major complications were recorded, and patient satisfaction increased from 29/40 to 36/40 during the program. Conclusions: implementing a high-intensity interventional program within a Family and Community Medicine residency is feasible and safe within our institutional framework. The threshold of 300 hours of supervised practice, under the direct guidance of an expert, is identified as a critical factor for consolidating motor skills and ensuring patient safety. This longitudinal model can offer a more robust framework for acquiring competencies compared to courses outside the residency, suggesting a solid reference for developing imageguided interventional skills in postgraduate training.
