Prevention And Control Measures Based On Targeted Surveillance Have Improved The Effectiveness Of Hospital Infection In ICU

Objective: To observe the effect of prevention and control measures on improving hospital infection in intensive care unit under the analysis data of target surveillance and pathogen resistance.Methods:1.From January 1,2015 to December 31,2017,1212 patients from tangshan people’s hospital were selected as the study subjects.Fill in the "registration form of targeted test for ICU patients" every day using targeted surveillance method to statistically analyze the infection sites,infection modes,drug sensitive test.2.Assess the clinical grade of the patients,and take targeted preventive measures according to the results of target surveillance and the average severity illnessscore(ASIS)score.Compare the infection rates between the beginning(January 1,2015 to June 6,2016)and the later(July 1,2016 to December 31,2017)stage of implying preventive and control measures.3.All data were analyzed by SPSS20.0 software,and the counting data were analyzed by chi-square test.P < 0.05 indicated statistical significance.Results:1.The study found that 1212 cases of patients at A and B time points were with similar diseases distribution: nervous system disease,tumor,respiratory system diseases,circulatory system disease,digestive system disease,fracture and injury,urogenital system diseases,nutritional and metabolic disease,blood disease;2.The rate of hospital-acquired infection of ICU was lower in B than A period of time,form 33.67% of A period down to 19.13% of B period.and clinical indicators also improved in B period than A period.The differences are of statistically significance.3.The composition of the infection site of ICU hospital acquired infection in A time part were as follows: lower respiratory tract infection(18.54%),entilator-associated pneumonia(48.29%),pleural cavity infection(1.46%),catheter associated urinary tract infections(19.51%),catheter-related bloodstream infections(2.93%),the nervous system infection(2.44%),gastrointestinal infection(3.90%),infection of incision(1.95%),and abdomen(basin)cavity infection(0.98%);in A time part were as follows: lower respiratory tract infection(15.70%),entilator-associated pneumonia(50.00%),pleural cavity infection(1.74%),catheter associated urinary tract infections(20.35%),catheter-related bloodstream infections(2.33%),the nervous system infection(2.91%),gastrointestinal infection(3.49%),infection of incision(1.74%),and abdomen(basin)cavity infection 1.74%.4.The distribution of pathogenic bacteria in time A was dominated by acinetobacter bauhinia(26.79%)and in time B was dominated by klebsiella pneumoniae(24.57%).5.The relative infection rate of the ventilator,catheter and arteriovenous catheter in time B was 11.52%,1.52% and 2.10%,respectively,lower than that in A time of 19.03%,1.99% and 2.34%.Conclusions: Targeted surveillance is an important method and guidelines to control acquired infection in ICU hospitals,targeted interventions are of great importance in controlling hospital-acquired infections.in response to targeted surveillance.
