Abstract

ObjectiveThis study aims to investigate the teaching effect of vascular simulation training (ST) in rotating vascular residents.DesignRetrospective cohort study.Setting and participantsA total of 95 vascular residents were included from 2015 to 2018 in a university affiliated centre western China, and divided into an ST group and a conventional training (CT) group. The ST group received ST and CT, and the CT group only received CT.Primary outcome measuresTheoretical scores were assessed, and the technique parameters, complications and radiation damage of the procedures were analysed.ResultsThe mean scores (8.74±1.09 vs 8.13±1.31) and the rate of willingness for retraining (93.62% vs 79.17%) in residents were higher in the ST group than in the conventional training (CT) group (p<0.05). The success rate of arterial puncture was significantly higher in the ST group (78.72% vs 58.33%, p=0.03); however, the incidence of complications was similar between the two groups (p>0.05). The time of the puncture procedure was significantly lower (9.56±5.24 vs 12.15±6.87 min), and the comfort score of the patient (5.49±1.72 vs 4.71±1.57) was higher in the ST group than in the CT group (p<0.05). At the end of the assessment, the learning time for angiography (3.65±0.64 vs 4.07±0.77 months) and the complete procedure time (33.81±10.11 vs 41.32±12.56 min) were lower in the ST group than in the CT group (p<0.01). The fluo time for angiography (489.33±237.13 vs 631.47±243.65 s) and the cumulative air kerma (401.30±149.06 vs 461.16±134.14 mGy) were significantly decreased in ST group (p<0.05).ConclusionThe application of a vascular simulation system can significantly improve the clinical performance of residents and reduce the radiation damage from a single intervention procedure in patients.

Highlights

In recent years, with changes in the disease spectrum of Chinese patients, the incidence of peripheral arterial disease has increased significantly, which has caused a severe economic and social burden.[1]
The baseline data of the two groups This study included 48 residents and 47 residents who were retrospectively recruited in this study, and there was no significant difference in baseline data between the two groups
The theoretical scores between both groups All residents passed the training test; the mean scores of the residents were higher in the simulation training (ST) group than in the conventional training (CT) group (8.74±1.09 vs 8.13±1.31, p=0.014)

Summary

Introduction

With changes in the disease spectrum of Chinese patients, the incidence of peripheral arterial disease has increased significantly, which has caused a severe economic and social burden.[1] it is becoming increasingly important to strengthen general and specialised vascular disease skills education in the training of medical residents.[2 3] In the past decade, the practical skills training of resident has been
