Interventional pain training using phantom model during COVID-19 pandemic

Interventional pain training using phantom model during COVID-19 pandemic

Background

Fluoroscopic‐guided lumbar procedures have increased in daily pain practice because the lumbar spine is one of the most common sources of pain. Interventional pain fellows must develop a minimum number of skills during their training in order to achieve the competences without neglecting radiological safety. However, medical training in fluoroscopic‐guided interventions is being affected by the current coronavirus disease 2019 (COVID‐19) situation.

Methods

The objective of this study was to evaluate the use of a phantom model for lumbar injection as a training strategy during the COVID‐19 pandemic in fellows of interventional pain. The study was divided into theoretical and practical modules. The hands‐on practice was performed in a lumbar model phantom where fellows were evaluated in four fluoroscopically guided approaches: intra‐articular facet block (IAFB), medial branch block (MBB), transforaminal block (TFB), and interlaminar block (ILB) divided in 5 sessions. The aim was to make as many punctures as possible in every session. We measured total procedural performance (TPP), total needle hand time (TNH), and total radiation dose generated by the fluoroscopic machine (TRD) during each procedure. Additionally, a survey was applied to evaluate confidence and satisfaction before and after training.

Results

A total of 320 lumbar punctures were completed. The results were statistically significant in all approaches attempted (p < 0.01). The fellow’s survey for satisfaction and confidence demonstrated a significant difference between pre and post‐test (p < 0.01).

Conclusions

The results of this study highlight the importance of adaptations and adoption of new educational models. The use of the phantom model for simulation could be a strategy for other emerging situations, like the COVID‐19 pandemic. Including this practice in the interventional pain programs could lead to better results for the patient and operator radiology safety.
