Abstract:
OBJECTIVE To observe the effect of early warning mechanisms based on nosocomial infection surveil-lance system on precise prevention and control of spread of multidrug-resistant organisms(MDROs)infections in intensive care unit of neurosurgery department.METHODS The dynamic monitoring was performed in the ICU of neurosurgery department of a three-A general hospital by using real-time surveillance system of nosocomial infec-tion from Jan.2023 to Dec.2023.The warning information was sent to the doctor' station immediately once the MDROs infections were detected,the detection of drug-resistant bacteria was carried out for the relevant personnel and their surroundings,and the precise prevention and control measures were implemented.The impact on the iso-lation rate of MDROs,isolation rate of MDROs from the relevant personnel and surroundings,incidence of noso-comial MDROs infections and incidence of surgical site infection was observed after the measures were taken.RESULTS The carrying rate of MDROs was decreased from 21.80％to 5.74％among the relevant personnel after the precise prevention and control measures were taken(P＜0.05),which was improved remarkably among the doctors(decreasing from 21.43％to 6.07％),nurses(decreasing from 23.68％to 3.98％),nursing workers(decreasing from 25.15％to 8.65％),and cleaning staff(decreasing from 25.49％to 5.05％)(P＜0.001).The isolation rate of MDROs was decreased from 20.77％to 7.12％among the surroundings(P＜0.05),which was decreased most remarkably among head cushions(decreasing from 32.28％to 12.13％),bed rails(decreasing from 16.70％to 3.27％),ventilator panels(decreasing from 23.00％to 6.95％)and bedside floors(decreasing from 31.99％to 9.96％)(P＜0.001).The incidence of nosocomial MDROs infections declined from 3.84％to 1.71％(P＜0.05),with incidence of incision infections decreasing from 4.00％to 1.45％(P＜0.05),the inci-dence of intracranial infections decreasing from 2.38％to 0.56％(P＜0.05).CONCLUSION The detection of drug-resistant bacteria is carried out immediately and precisely for the patients with MDROs infection,relevant personnel and their surroundings by using the real-time surveillance system of nosocomial infection,which achieve remarkable effect on prevention of transmission of MDROs and reduction of incidence of hospital-associated infec-tions and surgical site infections.
