Screening on key techniques used for surveillance and disposal of public health emergencies / 中华流行病学杂志

ABSTRACT

Objective To explore the key techniques used for surveillance and disposal of infectious diseases,food poisoning and hospital infection to improve the ability of surveillance and disposal on public health emergency.Methods Framework on surveillance and disposal of infectious diseases,food poisoning and hospital infection was set up,based on literature review and expert group discussion.Delphi method and technique for order preference by similarity to ideal solution comprehensive evaluation method were used for ordering preference by similarity,to screen key techniques set for surveillance and disposal of the above said events.Results Framework to be used for selecting key techniques was designed,based on the classification of emergency events,processing cycle of emergency events and level of techniques.Twenty six public health experts were selected for a 2-round consultation,with their authority as 0.796.Ten key techniques with important significance for surveillance and disposal of infectious diseases,food poisoning and hospital infection were selected from each event.Among these key techniques,the early-warning system was recognized as the key technique,important for the surveillance and disposal of all three emergency events.Items as technology used for unknown pathogenic microorganism detection,personal protection,gene sequencing and tracing technology,microorganism molecular typing technology,nucleic acid detection technology etc.were the key techniques and need to develop for the surveillance and disposal of infectious diseases and iatrogenic infection.Data regarding key technologies on security and privacy,early warning and forecasting,field rapid detection were sorted out that all in need to improve the surveillance programs on disposal of infectious diseases and food poisoning.Data exchange appeared another key technique on infectious diseases,with toxin detection and other 5 techniques the key techniques for food poisoning.Data collection,standardization and other 3 techniques appeared as the key techniques on iatrogenic infection.Conclusions Key techniques were selected in this study to meet the requirements of surveillance,disposal of infectious disease,food poisoning and iatrogenic infection.Authority of the experts got improved in the two-round consultation,ensuring the reliability of the results of screening and providing a scientific basis for the further research and priority development of the key techniques.
