Abstract
OBJECTIVES: To validate the newly designed ultrasound-guided suprapubic catheter insertion trainer (US-SCIT) model against the real life experience by enrolling participants with prior confidence in the technique of US-guided suprapubic catheter (SPC) insertion. METHODS: The US-SCIT was self-constructed from common disposables and equipment found in the emergency department. A validation questionnaire was completed by all participants after SPC insertion on the US-SCIT model. RESULTS: Fifty participants enrolled in the study. Each participant had reported confidence in the SPC insertion technique, prior to participation in this study. There were 13 "super-users" (>65 previous successful real life SPC insertions) in the study. The total material cost per US-SCIT unit was 1.71 USD. The US-SCIT's value in understanding the principals of US-guided SPC insertion had a mean score of 8.86 (standard deviation [SD] 1.03), whereas its value in simulating contextual anatomy had a mean score of 8.26 (SD 1.48). The mean score of the model's ability to provide realistic sensory feedback was 8.12 (SD 1.78), whereas that of realism of initial urine outflow was 9.06 (SD 1.20). Simulation with the model compared well with real life SPC insertion, with a mean score of 8.30 (SD1.48). CONCLUSIONS: The US-SCIT model performed well in various spheres developed to assess its ability to simulate real life SPC insertion. We are confident that this low-cost, validated, US compatible SPC trainer, constructed from common material present in the ED, will be a valuable learning asset to trainees across the globe.
