Unplanned tracheal extubation in the pediatric intensive care unit before and after quality management / 中国小儿急救医学

ABSTRACT

Objective To analyze the causes of unplanned tracheal extubation in mechanically ventilated patients in the pediatric intensive care unit using quality management practices and observe the changes of extubation rates before and after implementing these practices.Methods In the first place,we set up quality management group in June 2014.Second,the team formulated a risk factor checklist for unplanned tracheal extubation based on literature research, and analyzed the main causes requiring tracheal extubation. The last time,we developed some management measures for important reasons in 2014,and established and implemented a quality management strategy between 2015 and 2016.The incidence frequency of unplanned tracheal extubation,i. e. the number of extubation cases per 100 days with a tube in place(mechanical ventilation days),was used to evaluate the change of the extubation rates before and after implementing the new measures. The cases in 2014 were retrospectively analyzed,and cases from 2015 to 2016 were prospectively collected.The number of interval days for two continuity unplanned extubation was considered to be a means of quality control.Results Rick factors associated with unplanned extubation in the pediatric intensive care unit before implementing quality management were a delay of the replacing adhesive bandage, lack of sedation assessment,which were related to frequent physician replacement and insufficient training and supervision.In consideration of the identified risk factors,a standard operating procedure was formulated to prevent unplanned extubation,including standard operating procedure of tracheal catheter fixation and the sedation assessment. There were 484 mechanical ventilation in 2014,and the incidence of unplanned extubation was 0.8%,and the median number of days of separation was 8.0(4,20) d.Between 2015 and 2016,there were 1 379 mechanical ventilations,and the incidence of unplanned extubation was 0.2%,and the median number of days of separation was 34.0(19,61) d.The incidence of unplanned extubation in 2015 to 2016 was lower than that in 2014(χ2=5.936,P=0.018).Ramsay scoring usage increased from 28.6% in 2014 to 57.1% between 2015 and 2016,while Ramsay scored 3-4 points from 2015 to 2016 was higher than 2014(P< 0.05).Conclusion Establishing the quality management group according to the requirements of each hospital and implementing quality management strategies can reduce the incidence of unplanned extubation,thereby improving the quality of care in pediatric intensive care unit.
