RESUMO
Objective To investigate hand hygiene(HH) status among health care workers(HCWs) in municipal hospitals in Chongqing City, and provide the basis for making effective HH management strategies.Methods In April-June 2016, HH status among 111 HCWs in 24 municipal hospitals of this city were investigated through questionnaire survey, on-site observation, and hand surface sampling.Results All surveyed departments are installed special hand washing facilities, all surveyed HCWs were performed HH through hand-washing by running water.The proportion of HCWs' hand-washing by disinfectant was higher than six-step hand washing (73.87% [n=82] vs 37.84%[n=42], χ2=29.23, P<0.01);the implementation rate of HH before touching patient was higher than that after touching patients (99.10%[n=110] vs 89.19%[n=99], χ2=9.88, P<0.01).During the process of diagnosis and treatment activities, the maximal total number of bacteria on the surface of hand before and after HH were 475 CFU/cm2 and 85 CFU/cm2 respectively, hand surface colony count after HH was higher than before HH(P<0.01).Age, gender, department, and occupation are important factors influencing HH.The total number of bacteria on hand surface of nurses was higher than non-nurse HCWs, the total number of bacteria on hand surface of female, nurses, and HCWs in class I environment were all higher than male, non-nurse HCWs and HCWs in other types of environment, there were significant difference among the groups (all P<0.05).Qualified rates of HH of each group improved after hand washing, the total number of bacterial colony on hands of HCWs all decreased.Conclusion Hand washing facilities and HH efficacy are good in Chongqing municipal hospitals, however,HH compliance needs to be improved among HCWs aged≥35 years,male HCWs, HCWs in class III and IV environmental departments, as well as non-nurse HCWs.
RESUMO
Objective To understand the current status of disinfection and sterilization of medical institutions at all levels in 30 counties in Chongqing ,and to guide the work that medical institutions regulate and improve the quality of disinfection and steriliza‐tion ,and urge the relevant departments to strengthen the monitoring of disinfection quality of medical institutions .Methods Using field investigation and sampling inspection method ,the disinfection quality of medical institutions at all levels in 30 counties of Chongqing city was monitored and analyzed .Results From 30 districts and counties ,the medical institutions were sampled from 28 510 parts ,the overall average pass rate of 93 .3% .The qualified rate of medical institutions at all levels from high to low were as follows ,the village health room (96 .7% ) ,urban community medical institutions (96 .6% ) ,district level medical institutions (96 .1% ) ,individual clinic (90 .9% ) ,private hospitals (93 .7% ) and township (street) medical institutions (86 .5% ) .Different types of medical institutions got different qualified rate ,and the difference was statistically significant(χ2 =666 .84 ,P<0 .01) .Pro‐ject with the lowest qualified rate was radiation intensity of ultraviolet lamp(52 .8% ) ,secondly was indoor air (80 .4% ) and differ‐ent projects′qualified rate was significantly different(χ2 =1 706 .81 ,P<0 .01) .Conclusion Medical and health institutions at all levels′s disinfection quality were generally good ,but the village health room monitoring coverage ,ultraviolet light intensity and oth‐er individual monitoring projects need to be improved .
