RESUMO
Objective To investigate the occurrence of healthcare-associated infection(HAI)in different weight groups of neonates in neonatal intensive care unit (NICU)and general neonatal wards,and find out the high risk factors for HAI.Methods Targeted monitoring on hospitalized neonates in the neonatal department of a hospital in 2016 and January-November 2017 was prospectively surveyed,HAI rate,device usage rate and device-associated in-fection rate in different weight groups of neonates in NICU and general neonatal wards were compared.Results From 2016 to November 2017,a total of 3 872 neonates were monitored,the total hospitalization days were 42 427 days,56 patients had 62 cases of infection,HAI rate and HAI case rate were 1.45% and 1.60% respectively.HAI rate and HAI case rate in NICU were 5.28% and 6.03% respectively;HAI rate and HAI case rate in general neo-natal wards were both 0.46%,constituent ratio of septicemia ranked first of infection in both NICU and general neonatal wards,accounting for 43.75% and 50.00% respectively,followed by lower respiratory tract(LRT)infec-tion,accounting for 27.08% and 21.43% respectively.HAI rate of different weight groups of neonates in NICU and general wards were both significantly different(χ2＝107.78,46.65,respectively,both P＜0.0001),the lower weight of the neonates,the higher HAI rate;ventilator usage rate in neonates was positively correlated with HAI (r＝0.973,P＝0.027),the higher device usage rate,the higher HAI rate.Fungal septicemia rate per 1 000 days in rainy season was higher than that of non-rainy season (0.53‰ vs 0.37‰).A total of 70 specimens were detected, 45 strains of bacteria and fungi were isolated,pathogens were all from LRT and blood system,Pseudomonas aeru-ginosa was the main pathogen from LRT,Klebsiella pneumoniae and Candida krusei were the main pathogens from blood system.Conclusion Targeted monitoring on neonatal HAI can timely find out high risk factors for neonatal HAI,analyze the causes of infection,formulate corresponding prevention and control measures,reduce HAI rate, and ensure the medical safety of neonates.
RESUMO
Objective To systematically evaluate the compliance and correct rate of hand hygiene(HH) among doctors and nurses in secondary and above hospitals in mainland China,and provide data support for HH promotion.Methods Literatures about study on HH in mainland China after 2015 were retrieved from Chinese and English databases,researchers evaluated the literatures according to the relevant standards,screened the qualified literatures and extracted the data strictly according to the inclusion and exclusion criteria,Meta analysis was adopted to analyze the compliance and the correct rate of HH of doctors and nurses in different levels of hospitals and at different departments.Results The overall compliance rate of HH of nurses was higher than doctors,compliance rates of HH of doctors and nurses were 55.9％ (95 ％CI:45.9％,65.8％) and 66.0％ (95％CI:58.8％,73.1％) respectively;HH correct rates of doctors and nurses were 65.2％ (95％CI:53.6％,76.9％) and 67.9％(95％CI:56.9％,78.9％) respectively.Compliance rates of HH of doctors and nurses in tertiary hospitals were both higher than secondary hospitals,compliance and correct rates of HH of doctors and nurses in intensive care unit were both higher than general departments.Conclusion The compliance and correct rate of HH in mainland China need to be further improved,especially the promotion in primary hospitals and general departments.
