浦东新区医疗机构连续2年医院感染现患率调查分析
Prevalence rates of healthcare-associated infection in medical institutions in Pudong New Area for two consecutive years
摘要
Abstract
Objective To investigate the prevalence of healthcare-associated infection(HAI)in medical institutions in Pudong New Area.Methods Ten medical institutions in Pudong New Area were selected as monitored hospitals, cross-sectional survey on HAI in each hospital at a given day of November 2013 and November 2014 were conduc-ted.Prevalence of HAI in different levels of hospitals were compared.Results The prevalence rates of HAI in 2013 and 2014 were 4.04% and 3.75% respectively,there was no significant difference between two years(χ2 =0.709,P=0.400).The prevalence rates of HAI in primary,secondary,and tertiary hospitals in 2013 were 0.66%,3.32%, and 4.60% respectively,in 2014 were 0,3.52%,and 4.01 % respectively,prevalence rates of HAI in different lev-els of hospitals of each year were significantly different (all P <0.05).Prevalence rates of HAI were high in depart-ments of neurosurgery,hematology,intensive care units(ICUs),and gerontology.The prevalence rate of infection in ICUs increased obviously,from 10.09% to 18.78% (χ2 =3.921 ,P =0.048),departments of gerontology de-creased obviously,from 10.07% to 5.02%(χ2 =5.698,P =0.017).The main HAI sites were lower respiratory tract (36.72%),upper respiratory tract (9.96%),and urinary tract (12.89%).172 pathogenic isolates were de-tected in 2013,and 177 were detected in 2014,gram-negative bacteria,gram-positive bacteria,and fungi accounted for 60.74%,26.37%,and 12.89% respectively.Constituent ratios of pathogens causing HAI between two surveys were not significantly different (χ2 =5.819,P =0.830).Conclusion Among different levels of hospitals in Pudong New Area,tertiary hospitals have the highest prevalence rate,HAI in ICU increases obviously,the main HAI site is lower respiratory tract,the main pathogens are gram-negative bacteria.关键词
