供应室消毒工作是预防和控制医院感染的必要手段，加强对化学消毒剂的严格管理和合理使用又是取得最佳消毒效果的重要保证。因此在消毒剂的选择和使用上应加强管理，严格把关
ObjectiveTo study the effect of PDCA cycle model on the standardization of the application of common disinfectants, in order to promote the management level of hospital disinfection. MethodsBy questionnaire and observation, the study was to learn the knowledge and its application in medical workers on common disinfectants. Based on the results, we tried to regulate effective preventive measures and carry out continuous improvements. ResultAfter the implementation of PDCA cycle model, the awareness rate of the medical staff on disinfection and the application accuracy of disinfectants were significantly increased (P<0.05). ConclusionThe implementation of PDCA cycle model can improve nosocomial infection management level effectively, ensure medical quality management and patients' safety, which is an effective way of management to reduce the rate of nosocomial infection.
Objective To evaluate the disinfection efficacy of alcohol-based hand disinfectants for medical glove surface in continuous operation, and explore approaches of improving hand hygiene compliance. Methods Between March and July 2015, and between March and July 2016, all the nurses (n=5) in Blood Collection Room of Outpatient Department with many patients and frequent sterile operation needed were included in this study. Nurses wearing gloves for hand hygiene and disinfection between March and July 2016 were regarded as the observation group, and those who used alcohol-based disinfectants for routine hand hygiene without gloves between March and July 2015 were designated into the control group. The hand hygiene compliance was compared between the two groups. From March to July 2016, alcohol-based hand disinfectants were used for disinfection on the glove surface during continuous blood sampling by nurses with gloves on their hands. Fifty samples were collected respectively after the gloves were used for 1, 2, 5, 10, and 15 continuous times for blood sampling. Then, the samples were sent to the bacteriology room for culture. Results All of the 250 samples were qualified, and the bacterial colonies on the surface of gloves were equal to 10 cfu/mL2 or lower. NoStaphylococcus aureus,Escherichiacoli or other pathogens were detected on the glove surface. However, after the gloves were continuously used for 15 times, the gloves of two nurses could not meet the research criteria again because of significant sweating. Conclusions In the process of continuous blood sampling, it is effective to use alcohol-based hand disinfectants to disinfect the surface of medical gloves, which can promote hand hygiene compliance to a certain extent. However, there is a certain limit on the times of usage for medical gloves.
Objective To study the disinfection effect of hand disinfectants containing alcohol after heating, and the comfortable feeling of using warm disinfectants among the medical staff in operation rooms. Methods Between November 2016 and January 2017, we analyzed the disinfection effect of two alcohol-containing hand disinfectants after heating in operation rooms through on-the-spot disinfection and inspection. Questionnaire was used to investigate the comfortable feeling of using warm hand disinfectants. Results After standing for 7 days at a temperature of 37℃, the major content of the two disinfectants decreased by less than 10%. Three minutes of disinfection by using the two kinds of disinfectants had an average natural-bacteria killing logarithm higher than 1.00, and they both had a qualified disinfection effect. Moreover, 96.7% of the medical personnel believed that warm disinfection products were more comfortable. Conclusion After heating, the two kinds of alcohol-containing hand disinfectants are effective in hand disinfection and more comfortable to use, which can improve hand hygiene compliance in surgical staff.
ObjectiveTo explore a better hygienic hand disinfection method to improve hand hygiene compliance, by evaluating and comparing the disinfection effects and the economic and time cost expenditures of three different types of hygienic hand disinfection methods.MethodsFrom March to July 2016, patients undergoing blood collection were randomly divided into three groups, and five blood collection nurses used one different type of hygienic hand disinfection method in each group when performing blood collection operation on the patients, including: direct hygienic hand disinfection (group A); wearing gloves, and doing hygienic hand disinfection without putting off gloves (group B); and changing gloves for each patient, and doing hygienic hand disinfection after putting off gloves (group C). Two hundred and ten specimens of the nurses’ hands or gloves surface after hand hygiene were collected from each group for the comparison of hygienic hand disinfection effect, and the differences in economic cost and time cost were compared.ResultsThe passing rates of the disinfection effect of the three different types of sanitary hand disinfection methods were all 100%. The economic cost of group A, B, and C was 9.66, 21.98, and 185.66 yuan, respectively, and the time cost of group A, B, and C was 5 250, 6 860, and 14 700 seconds, respectively. No sharp injury occurred.ConclusionSince direct hygienic hand disinfection does not implement the standard prevention principle, the method of wearing gloves and doing hygienic hand disinfection without putting off gloves is the best in the three different hygienic hand disinfection methods, which not only has the same disinfection effect, but also can save economic cost and time cost, which may improve the medical personnel’s hand hygiene compliance.
ObjectiveTo investigate the problems in the use of quick-drying hand disinfectants and formulate intervention measures to improve the hand hygiene compliance of nursing staff.MethodsFrom February 2014 to June 2016, the hand hygiene compliance of nursing staff was continuously observed according to the hand hygiene observation table recommended by the World Health Organization. The questionnaire on the use of quick-drying hand disinfectants, which passed the reliability and validity test, was used to find out the reasons leading to the low compliance rate of hand hygiene among nurses, and pertinent interventions were formulated. From November 2016 to December 2017, intervention measures were gradually implemented throughout the hospital, and the hand hygiene compliance of nursing staff was continuously observed again. Then we compared the compliance rate of hand hygiene and the compliance rate of hygienic hand disinfection among nurses in the second quarter of 2016 (before intervention) with those in the last quarter of 2017 (after intervention).ResultsThe compliance rates of hand hygiene and hygienic hand disinfection among nurses before intervention were 62.15% and 49.77%, respectively, and those after intervention were 91.64% and 90.80%, respectively. The differences were statistically significant (P<0.05).ConclusionThe factors affecting the hand hygiene compliance of nursing staff are identified through questionnaires and targeted intervention measures have effectively improved the hand hygiene compliance rate of nursing staff.
