    Abstract:
    INTRODUCTION: The aim of this study was to determine the number of ultrasound-guided (USG) central venous catheterization (CVC) of the internal jugular vein (IJV) residents had to perform, after a simulation-based training program, to achieve optimal clinical outcomes. METHODS: We conducted a single-center, prospective, observational study in the medical intensive care unit of a university-affiliated teaching hospital. Residents participated in a formal training program, consisting of a simulation-based workshop and 5 supervised USG CVC insertions on patients. Subsequent USG CVC of the IJV performed by residents during their rotation were assessed. Data on the overall success (OS), first pass success (FP) and mechanical complication (MC) rates were serially collected over 2 years, spanning 4 cohorts of residents. RESULTS: Thirty-two residents performed a total of 337 USG CVC of the IJV. Residents had previously performed an average of 9 CVC via the landmark technique. None had performed USG CVC before. Results showed that residents improved in their OS, FP, and MC rates as they performed more USG CVC. Residents needed to perform 7 USG CVCs to achieve optimal clinical outcomes of high OS and FP as well as low MC rates. There was a significant improvement in OS, FP, and MC rates for the eighth and subsequent USG CVCs compared with the first 7 USG CVCs (82% vs. 99% [P < 0.001], 70% vs. 92% [P < 0.001] and 11% vs. 0%, respectively). CONCLUSIONS: After a formal training program consisting of a simulation-based workshop and 5 supervised USG CVCs on critically ill adults, residents were able to achieve optimal clinical outcomes after performing 7 procedures.
