BackgroundManaging acute pain is a common challenge in the emergency department (ED). Though widely used in perioperative settings, ED‐based ultrasound‐guided nerve blocks (UGNBs) have been slow to gain traction. Here, we develop a low‐cost, low‐fidelity, simulation‐based training curriculum in UGNBs for emergency physicians to improve procedural competence and confidence.MethodsIn this pre‐/postintervention study, ED physicians were enrolled to participate in a 2‐h, in‐person simulation training session composed of a didactic session followed by rotation through stations using handmade pork‐based UGNB models. Learner confidence with performing and supervising UGNBs as well as knowledge and procedural‐based competence were assessed pre‐ and posttraining via electronic survey quizzes. One‐way repeated‐measures ANOVAs and pairwise comparisons were conducted. The numbers of nerve blocks performed clinically in the department pre‐ and postintervention were compared.ResultsIn total, 36 participants enrolled in training sessions, eight participants completed surveys at all three data collection time points. Of enrolled participants, 56% were trainees, 39% were faculty, 56% were female, and 53% self‐identified as White. Knowledge and competency scores increased immediately postintervention (mean ± SD t0 score 66.9 ± 8.9 vs. t1 score 90.4 ± 11.7; p < 0.001), and decreased 3 months postintervention but remained elevated above baseline (t2 scores 77.2 ± 11.5, compared to t0; p = 0.03). Self‐reported confidence in performing UGNBs increased posttraining (t0 5.0 ± 2.3 compared to t1 score 7.1 ± 1.5; p = 0.002) but decreased to baseline levels 3 months postintervention (t2 = 6.0 ± 1.9, compared to t0; p = 0.30).ConclusionsA low‐cost, low‐fidelity simulation curriculum can improve ED provider procedural‐based competence and confidence in performing UGNBs in the short term, with a trend toward sustained improvement in knowledge and confidence. Curriculum adjustments to achieve sustained improvement in confidence performing and supervising UGNBs long term are key to increased ED‐based UGNB use.

Background Simulation-based training is effective for ultrasound (US)-guided procedures. However, commercially developed simulators are costly. This study aims to evaluate the feasibility of a hand-made phantom for US-guided paracentesis. Methods We described the recipe to prepare an agar phantom. We collected the US performance data of 50 novices, including 22 postgraduate-year (PGY) residents and 28 undergraduate-year (UGY) students, who used the phantom for training, as well as 12 emergency residents with prior US-guided experience. We obtained the feedback after using the phantom with the Likert 5-point scale. The data were presented with medians and interquartile ranges (IQRs) and analyzed by the Wilcoxon rank sum test. Results While emergency residents demonstrated superior performance compared to trainees, all trainees exhibited acceptable proficiency (global rating of ≥ 3, 50/50 vs. 12/12, p = 1.000) and comparable needle steadiness [5 (5) vs. 5 (5), p = 0.223]. No significant difference in performance was observed between PGYs [5 (4–5)] and UGYs [5 (4–5), p = 0.825]. No significant differences were observed in terms of image stimulation, puncture texture, needle visualization, drainage simulation, and endurance of the phantom between emergency residents and trainees. However, experienced residents rated puncture texture and draining fluid as “neutral” (3/5 on the Likert scale). The cost of the paracentesis phantom is US$16.00 for at least 30 simulations, reducing it to US$6.00 without a container. Conclusions The paracentesis phantom proves to be a practical and cost-effective training tool. It enables novices to acquire paracentesis skills, enhances their US proficiency, and boosts their confidence. Nevertheless, further investigation is needed to assess its long-term impact on clinical performance in real patients. Trial registration NCT04792203 at the ClinicalTrials.gov.
