重点环节干预在降低留置针堵管发生率中应用的效果评价

Effect evaluation of key-link interventions on reducing the incidence rate of indwelling needle catheter blockage

留置针堵管是造成留置针不能达到有效留置时间的一个重要原因,我科成立质量控制小组,从导管功能评估、冲封管时机及方法、固定夹位置及夹闭方法、健康教育四个方面实施重点环节干预。结果显示,干预后留置针堵管发生率由干预前的48.5%降为19.1%,差异有统计学意义(P<0.001)。说明加强重点环节干预,可有效降低留置针堵管发生率,并可保证质量持续改进。

Indwelling needle catheter blockage is an important reason of failing to achieve the effective duration of the indwelling needle. Our department established a quality team and carried out the key-link interventions from four key aspects, including the catheter function evaluation, flushing and sealing catheter time and method, fixed clamping position and method, and health education. The incidence rate of indwelling needle catheter blockage after intervention decreased significantly from 48.5% to 19.1%（P〈0.001）. Strengthening the key-link intervention could reduce the incidence rate of indwelling needle catheter blocking and guarantee a continuous improvement of the nursing quality.
