ABSTRACT
Objective To investigate compliance and influencing factors of hand hygiene (HH)among health care workers(HCWs).Methods From November 2014 to February 2015,implementation of HH among HCWs in 15 clinical departments in a hospital was investigated through questionnaires,the effect of HH purpose on HH behav-ior of HCWs was analyzed with multivariate logistic regression method.Results A total of 364 HCWs were investi-gated,245 (67.31% )of whom implemented HH well. Univariate analysis revealed that implementation of HH a-mong HCWs of different occupations,education levels,and HH purpose were all significantly different (all P<0. 05). Multivariate logistic regression analysis showed that HH purpose as well as HH compliance were both signifi-cantly different (P= 0.042). Compared with HH purpose of self-protection among HCWs,HCWs with HH pur-pose of cross-infection prevention had better HH behavior (OR,2.17[95% CI,1.29-3.65]).The top five objective factors influencing HCWs'HH implementation were as follows:lack of warm water in winter (70.73% ),heavy workload,had no time (61 .38% ),skin irritation caused by disinfectant or hand sanitizer (54.88% ),without hand dryer (47.56% ),and use disposable gloves (45.12% ).Conclusion On the basis of improving HH facilities,chan-ging HCWs'awareness of HH only for self-protection may be an another way to improve HH compliance among HCWs.
ABSTRACT
Objective To evaluate the effect of comprehensive intervention measures on reducing the bacterial colonization of the intensive care unit (ICU)bedside notebook computer keyboards and mice.Methods According to bacterial contamination of ICU bedside notebook computer keyboards and mice,comprehensive intervention meas-ures were taken (including wiping computer keyboards and mice with alcohol twice a day,intensifying hand hy-giene,and monitoring hand-washing compliance),specimens of keyboards and mice were taken,bacterial detection results were analyzed.Results Before intervention,bacterial counts of keyboards and mice of 8 specimens were all>5 CFU/cm2 ,detection rate of Bacillus subtilis was 64.71 %,Micrococcus ,coagulase negative staphylococcus, Acinetobacter baumannii ,and Klebsiella pneumoniae were 17.65%-58.82%,Escherichia coli and Acinetobacter calcoaceticus were both 5.88%.After comprehensive intervention measures were taken,bacterial counts of only two specimens of keyboards and mice were >5 CFU/cm2 ,the qualified rate of monitoring result after intervention was significantly higher than before intervention (88.24% vs 52.94%;χ2 =5.10,P <0.05).Conclusion Compre-hensive intervention measures can significantly reduce bacterial count on ICU bedside notebook computer keyboards and mice,and decrease the occurrence of healthcare-associated infection.
ABSTRACT
Objective To investigate the occurrence of intraoperative occupational exposure to blood among sur-geons in a hospital,so as to make effective precaution measures.Methods Combined with questionnaires,the mo-nitoring data of occupational exposure to blood among surgeons from June 2011 to June 2013 were analyzed statisti-cally.Results A total of 49 surgeons sustained 115 times of occupational exposure to blood,including 42 times (36.52%)in general surgery surgeons,36 (31 .30%)in orthopedic surgeons,31 (26.96%)in obstetrics and gyne-cology surgeons,and 6(5.22%)in urinary surgery surgeons.The main occupational exposure were sharp injuries (n=71 ,61 .74%),blood and body fluid splashing were 44 times (38.26%);the top two exposed sites were hands (49.57%)and faces (17.39%).88.70% of exposed cases were given emergent treatment,and 55.65% of exposed cases were reported.The follow-up found no surgeons were infected after the prompt and correct treatment. Conclusion Surgeons are at high risk of occupational exposure.Occupational precaution should be strengthened, occupational awareness and ability of HCWs should be enhanced,and post-exposure treatment should be improved.
ABSTRACT
Objective To investigate healthcare-associated infection(HAI)prevalence and antimicrobial use in a hospital.Methods HAI prevalence rate,antimicrobial use and pathogen detection in all inpatients on August 21 , 2013 were investigated with cross-sectional survey method.Results A total of 2 238 inpatients were investigated, 104 patients developed 126 times of HAI,HAI prevalence rate and case rate was 4.65% and 5.63% respectively;the top four sites for HAI were lower respiratory tract (28.57%),upper respiratory tract(18.25%),urinary tract (7.94%)and gastrointestinal tract(4.76%).Rate of specimens delivered for detection was 91 .35%(95/104),the main specimen was sputum (26.32%),followed by blood (25.26%)and urine (10.53%).Antimicrobial usage rate was 24.58%,therapeutic,prophylactic plus therapeutic,and prophylactic use accounted for 36.55%,45.09%, and 18.36% respectively;the usage rate of single,combination of 2,and 3 antimicrobial agents accounted for 75.82%,20.91 % and 3.27% respectively.Risk factors of HAI were age (60 years),all kinds of inva-sive procedures (tracheotomy,mechanical ventilation,urinary catheterization,arteriovenous intubation,hemodialy-sis),and anti-tumor chemotherapy.Conclusion Survey on HIA prevalence helps to know the occurrence of HAI and usage of antimicrobial agents,as well as risk factors and high-risk departments of the occurrence of HAI,it also provides basis for subsequent targeted monitor on HAI.
