The role of evidence-based methods used in medical devices safety monitoring / 重庆医学

ABSTRACT

Objective To monitor flow rate accuracy of the infusion pump and injection pump by using evidence-based methods , and to provide the basis for management and monitoring of medical clinical devices .Methods The flow rate accuracy of 188 infusion pumps and 253 injection pumps in the hospital were monitored ,the correction between instrument using length ,maintenance fre-quency and the flow rate accuracy were analyzed .And compared the impact of flow rate accuracy affected by instruments using length and maintenance frequency .Results The flow rate accuracy of infusion pumps and injection pumps in the hospital were 47 .34% and 79 .84% ,the instrument using length had no effect on flow rate accuracy (P> 0 .05) ,and the pass yield of maintain regular was higher the irregular maintaining ,the longer of maintenance cycle the lower of pass yield (P<0 .05) .Conclusion Using evidence-based methods in medical devices safety monitoring can help deep discover potential safety hazards ,identify problems and provide scientific solutions .
