ABSTRACT

Objective To understand the current situation of pressure steam sterilization in medical institutions in Xi'an city,and provide reference for the monitoring and quality control of pressure steam sterilization.Methods Central sterile supply departments(CSSDs) in medical institutions in Xi'an in 2012-2014 were investigated.Physical,chemical,and biological monitoring methods were used to evaluate the pressure steam sterilizers.Results A total of 135 medical institutions in Xi' an were monitored,including 40 tertiary medical institutions and 95 secondary and below medical institutions.A total of 540 specimens were collected,454 were qualified,overall qualified rate was 84.07 %.Qualified rate of monitoring result of pressure steam sterilization of tertiary medical institutions was higher than secondary and below medical institutions(93.13 % vs 80.26 %,x2 =13.91,P<0.01).Qualified rates of chemical PCD and biological test pack of tertiary as well as secondary and below medical institutions were 100% and >90% respectively.The qualified rate of recoded temperature in secondary and below medical institutions was 88.42 %,but actually measured temperature was 38.95 %,which was significantly lower than 72.50 % of tertiary medical institutions(x2 =12.68,P<0.01).The rates of the measured temperature> 134℃ of pressure steam sterilizer in each year were all low,but measured temperature<132℃ was about 50.00 %,difference between actually measured temperature and recorded temperature was-4℃-1 ℃,difference between-2.5 ℃-0.5℃ accounted for 80.00%,the main unqualified temperature was 130℃-131 ℃,accounting for 82.61 %.Conclusion Efficacy of pressure steam sterilization is different in different levels of medical institutions in Xi'an,physical monitoring measures are not standardized,the supervision of physical parameters in key sectors should be strengthened to ensure the sterilization quality of medical institutions and reduce the occurrence of iatrogenic infection.

ABSTRACT

Objective To investigate the current status of hand hygiene(HH) among health care workers(HCWs) in clinical laboratories in medical institutions in Xi'an City.Methods HH status of HCWs in clinical laboratories in medical institutions in Xi'an was performed random on-the-spot sampling and monitoring.Results A total of 240 HH specimens of HCWs in clinical laboratories in 80 medical institutions in Xi'an City were collected, 127 detected results were qualified, the total qualified rate was 52.92%.The qualified rates of medical institutions were as follows: municipal hospitals 62.67%,workers' hospitals 55.95%,private hospitals 40.74%;comprehensive medical institutions 67.68%,specialized medical institutions 42.55%;tertiary medical institutions 79.63%(n=43),secondary and below medical institutions 45.16%(n=84),there were significant differences in HH qualified rate among HCWs in different types of medical institutions(all P<0.01).Of different HH detection items, detection rates of Escherichia coli and Staphylococcus aureus were 0.83% and 8.33% respectively.There were significant differences in HH compliance rates among HCWs of all age groups(χ2=9.103,P<0.05), HCWs aged≥50 years had the highest qualified rate of HH(71.43%), followed by those aged<30 years (67.82%),HCWs in 40~ year age group had the lowest HH qualified rate (39.66%).Conclusion The qualified rate of HH of HCWs in clinical laboratory of medical institutions in Xi'an City is low, it is necessary to enhance the procaution awareness of HCWs in clinical laboratories, strengthen quality control of HH, strictly implement standard hand-washing procedures to reduce occurrence of HAI.

ABSTRACT

Objective To understand environmental quality status of clean operating rooms in municipal hospitals of Xi’an,and provide reference for ensuring the clean quality of operating rooms.Methods On-site specimen collec-tion and detection were conducted to detect and analyze the cleanlinss of air in clean operating rooms in 15 hospital of Xi’an.Results A total of 51 operating rooms were monitored,secondary and tertiary hospitals had 24 and 27 operating rooms respectively;26 were grade-I and 25 were grade-Ⅲ operating rooms.The qualified rates of dust particle≥0.5μm/particle size in grade-I and grade-Ⅲ clean operating rooms were 76.92% and 80.00% respective-ly,≥5μm/ particle size were 73.08% and 88.00% respectively.The qualified rates of dust particle counts in grade-I and grade-Ⅲ clean operating rooms were 61 .54% and 80.00% respectively,difference was not significant(χ2=2.092,P >0.05 ).The qualified rate of dust particle counts in clean operating rooms in tertiary hospitals was significantly higher than secondary hospitals(85.19% vs 58.33%,χ2 =4.600,P 0.05),in surrounding zone were 95.83% and 92.59% respectively (both P >0.05).Conclusion Dust particle and airborne microbes in some clean operating rooms in municipal hospitals of Xi’an are beyond the standard,supervi-sion and management should be strengthened.

ABSTRACT

Objective To investigate the status of disinfection and sterilization quality of different levels of medical institu-tes in Xi’an,and improve the management level of disinfection and sterilization of medical institutes. Methods Disinfection and sterilization efficacy of 69 medical institutes were monitored and evaluated according to Standardization for Disinfec-tionTechniques (2002 edition)and Sanitary Standards for Hospital Disinfection (GB15982-1995). Results From 2011 to 2013,2 224 specimens were tested,1 766 (79.41% )were qualified.The qualified rate of tertiary medical institutes was higher than second and below medical institutes (83.67% vs 77.50% ,P= 0.001),the qualified rate between public medical institutes and private medical institutes was not statistically different (79 .64% vs 78 .20% , P= 0.532),the qualified rate of comprehensive medical institutes was higher than specialized medical institutes (80.18% vs 74.92% ,P= 0.030). Of different detected specimens,the qualified rates of disinfectant in use and pressure steam sterilizers (including test pack and process challenge device)were higher (98.46% ,100.00% ,and 98.06% respectively),while the hands of health care workers (HCWs)and glutaraldehyde were lower(58.48% and 43 .28% respectively).Conclusion Disinfection and sterilization quality in different medical institutes in Xi’an is dif-ferent,and different disinfected and sterilized objects are also varied .It is necessary to intensify the management of hand hygiene of HCWs and concentration of glutaraldehyde.
