ABSTRACT

Introduction: Thyroid nodules are a frequent clinical problem, for which ecography-guided fine needle puncture is an essential tool. Studies show that investing hours on practicing this technique improves the diagnostic outcomes. Objectives: To develop a low-cost thyroid puncture simulation model, and its assessment tool. Material and methods: Both existing literature and experts experience were consulted. An iteration process was conducted for the elaboration of the thyroid puncture model, with constant expert consultation. The following parameters were assessed: echogenicity, punctionability, consistency, anatomic resemblance, and cost. The assessment tool was built from expert consensus with the election of key items for the procedure. Results: A model achieving an acceptable level of echogenicity, punctionability, consistency and anatomic resemblance was built, and approved by local experts. The cost per model was USD 2,6, with an average duration of four weeks. Punction attempts depend on the number of nodules added to each model. The assessment tool developed consisted on twelve items related to technical and clinical aspects of the procedure. This rating scale was created for both clinical and simulated environments. Conclusion: We present a thyroid puncture model, which is both low-cost and easily reproduced, along with its assessment tool. Future challenges consist on developing a validated training program based on this model.
