ABSTRACT
Objective To study whether methicillin-resistant Staphylococcus aureus (MRSA)will increase the burden of patients with hospital-acquired pneumonia (HAP).Methods Patients with Staphylococcus aureus HAP in a hospital between January 1 ,2013 and November 31 ,2014 were selected,patients with MRSA HAP were as case group,patients with methicillin-sensitive Staphylococcus aureus (MSSA)HAP were as control group,propen-sity score matching (PSM)analysis were conducted to compare the prognosis of MRSA HAP and MSSA HAP (length of hospital stay, duration from infection to discharge, mortality, total therapeutic cost ). Results APACHE II score in case group was higher than control group before PSM was conducted,length of hos-pital stay and duration from infection to discharge were both longer than control group (40[20,94]d vs 28[21 ,53] d;19[10,46]d vs 17[8,29]d,respectively,both P 0.05 ),data were balanced and comparable;there were no significant difference in length of hospital stay between two groups (28[21 ,52]d vs 28[21 ,53]d),duration from in-fection to discharge (15[9,25]d vs17[8,29]d),mortality(10.87% vs 15.22%),and total therapeutic cost (121 013.5[80 747.21 ,176 200]yuan vs 119 911 .2[66 994.08,241 184.7]yuan)(all P >0.05).Conclusion APACHE II score is an important factor affecting prognosis;after balancing this factor,there is no difference in the prognosis of patients with MRSA and MSSA HAP,MRSA HAP can not increase the burden of disease.
ABSTRACT
Objective To investigate the contamination of clinically used tablet computers,and compare the effec-tiveness of three cleaning and disinfection methods.Methods The front and back surfaces of tablet computers were wiped and detected by handheld adenosine triphosphate (ATP)fluorescence detector,the study was divided into baseline stage and cleaning and disinfection stage.During baseline stage,the tablet computers in use were directly wiped,during cleaning and disinfection stage,the tablet computers were wiped by normal saline-moistened gauze, alcohol-moistened gauze,and wet napkin.Results During baseline stage:20 tablet computers were wiped,the qualified rate was 0,the median of relative light unit (RLU)of ATP detection was 218.00.During cleaning and dis-infection stage,10 tablet computers were wiped in each cleaning and disinfection group,and the qualified rate of normal saline-moistened gauze,alcohol-moistened gauze,and wet napkin groups were 50.00%,0,and 60.00% re-spectively,the median RLU of ATP detection were 28.50,79.00,and 29.00 respectively.Except comparison be-tween saline-moistened gauze and wet napkin groups (P =0.97),multiple comparison of RLU of ATP detection amongthe other groups were significantly different (all P <0.001 ).Conclusion Contamination of medical tablet computers are serious,wet napkin wiping is an ideal method for cleaning and disinfection,but the frequency for cleaning and disinfection needs to be further studied.
ABSTRACT
<p><b>OBJECTIVE</b>The aim of this study was to explore the association between acquired multi-drug resistant organism (MDRO) and ventilator-associated pneumonia (VAP) in patients hospitalized at the intensive care unit(ICU).</p><p><b>METHODS</b>Real-time monitoring system for hospital infection was used to track VAP patients. The period of study was from January 1, 2013 to December 31, 2013. Both a nested case-control study design and logistic multivariable regression model were performed to explore the association.</p><p><b>RESULTS</b>A total of 142 VAP cases and 342 non-VAP controls were available in this study. Duration of Hospital stay, ICU stay and mechanical days were statistically significant between the case and the control group (P≤0.001). Compared with MDRO negative patient, the MDRO colonization or infection patients showed an 3.05-time increase on the risk of VAP (adjusted OR = 4.05, 95% CI:2.51-5.46). Remarkably,MDRO-positive patients were significantly associated with increased duration of mechanical ventilation and antimicrobial drug use (P < 0.001).</p><p><b>CONCLUSION</b>MDRO colonized and infection patients would significantly increase the risks of VAP, with prolonged hospitalization and ICU stay. Effective measures should be taken to promote and control patient's safety at the hospital.</p>

Objective To analyze the present medical teaching textbooks and practice skill guidelines,and explore the profound causes of poor hand hygiene idea among doctors.Methods Three sets of unified textbook series used for domestic medical colleges and universities and two sets of manipulation skill guidelines were studies.Statistical method was conducted to analyze whether concepts and methods of hand hygiene,hand-washing and antiseptic han-drubbing were included in these teaching textbooks;as to eight aseptic manipulation skills,coverage of knowledge, steps of hand-washing and antiseptic handrubbing in manipulation skill guidelines were also analyzed.Results The mentioning rate of hand hygiene,hand-washing and antiseptic handrubbing in 8-year and 5-year program teaching textbooks were both 0 ,in nursing teaching textbooks was 1 00 % ;as to 8 aseptic manipulation in 2 sets of skill practice guidelines,mentioning rate of hand washing was 37 .50 % ,and method and steps of antiseptic handrubbing were both 0 .Conclusion School teaching and skill assessment are the basis,it is difficult to form the right idea by only relying on continuing education without basic education.Hand hygiene should be stressed in the written of teaching textbooks,guidelines should be written following the newest progress,so as to form the correct idea of hand hygiene among doctors.
ABSTRACT
Objective To realize the effect of WHO multimodal hand hygiene improvement strategy (MHHIS)on improving hand hygiene compliance of health care workers(HCWs).Methods From June to December 2012,HCWs in a hospital was intervened by adopting MHHIS,hand hygiene compliance rate before and after intervention was com-pared,and effectiveness of intervention was assessed.Results Hand hygiene compliance of doctors and nurses improved from 14.06%(35/249)and 28.62%(81/283)before intervention to 31.73%(79/249)and 57.60%(163/283)after inter-vention respectively(both P <0.05).Except outpatient and emergency department,hand hygiene compliance of the other departments significantly improved (all P <0.05);hand hygiene compliance of various hand hygiene indicators significantly improved except ‘after contact with patient surrounding’(all P <0.05),the differences were statistically different (P<0.05).Conclusion Using WHO MHHIS can effectively improve hand hygiene compliance of HCWs.
