by hepatitis B carriers under no antibodies of hepatitis B protection, the rate of infection is 6w30%. If they were pricked by carriers of hepatitis C, the infection rate is 2.7%. If we were pricked by HIV carriers, the infec-tion rate is 0.3w0.4%. It is very important to protect from needle pricks to get free from these diseases. The rate of needle pricks in our hospital is 0.22% in 2012. The top three causes are: 1. inappropriate force when needles pulled out accounted for 23%, 2. Pricked by sharp instruments during surgeries accounted for 23%, 3. Pricked by the other hand under unstable position accounted for 15%. The top three personnel subject to needle pricks are nurses (0.12%), physicians (0.05%), cleaning personnel (0.02%).
Methods: The pricks protection measures before enforcing safety needles which included 1. Developed needle pricks protection manual which con-tains the disposing process of needles and syringes after drawing blood 2. Trained employees and sanitation personnel with needle pricks prevention included in in-service and pre-service education 3. Set needle container and threw needles into containers directly without re-capping. We launched the use of safety needles since January 2013 and conducted education. We audited and consulted personnel by infection control nurse and retrieved the unsafe needles.
Results: By the implementation of safety needles, the rate of use is 100% in special units and in high-risk patients, 60% in whole hospital. The ratio of needle pricks dropped from 0.22% in 2012 to 0.15% in 2013.
Conclusion: There is a significant reduction in the ratio of needle pricks. We conducted 11 types of safety needles so far and will continue to promote. We hoped to give our employees more secure working environment by the policy.

ASSESSMENT OF KNOWLEDGE, ATTITUDE, FACTORS RELATED TO HAND HYGIENE AMONG HEALTHCARE WORKERS AT HUNG VUONG HOSPITAL T. T. M. Hanh , N. T. T. Tham, T. C. Cong. Hung Vuong Hospital, Ho Chi Minh City, Vietnam
Purpose: Since 2010, the hand hygiene compliance (HHC) rates of health care workers (HCWs) increased from 9% to 54% during the first 3 years of hand hygiene surveillane at Hung Vuong hospital, and remained stable at 54% in the following year. There was a need of assessment of knowledge, attitude, factors related to hand hygiene among HCWs that aimed to provide information for establish interventions to improve HHC.
Methods: A cross e sectional study uses modified validated questionnaires, which had given for 420 HCWs of clinical wards at begining of working day in October 2013. The questionnaire consists of four parts: demographic infor-mation, assessment of knowledge, attitudes, practices and equipment avail-able for hand hygiene. Knowledge, attitudes and current practice behaviours will be measured. HCWs need to fill the questionnaire and submit to infec-tion control nurses at the end of the day.
Results: The survey showed that 63% HCWs had false knowledge of reducing infection through their hands. Only 9% HCWs fully understood the advan-tages of alcoholebased hand rub, 42% HCWs felt reluctant to ask others to engage in HH, 11% HCWs didn’t feel embarrassed if they omitted HH. Some factors related to HH are: lacking of facilities, insufficient time,
forgetfulness, high patient-nurses ratio, frequent requirements of HH. There are some positive influences: 90% HCWs know that HH is an important task. 90.2% of HCWs agreed HH’s posters remind them of HH, 74.8% founded that infection control department have a positive impact on HH.
Conclusion: Lack of right knowledge of hand hygiene from HCWs, especially knowledge of alcoholebased hand rub advantages and lack of facilities to perform hand hygiene are the most important findings. There is the need for HH knowledge training and providing hand hygiene facilities to improve HHC of HCWs.

Purpose: Disinfection of hospital water supplies has been an effective method for prevention of waterborne-associated nosocomial infections. Chlorine dioxide (ClO2) has been applied to hospital water treatment for
eradication of Legionella. However, due to the difficulty of controlling ClO2 concentration in water, long-term efficacy varies from literature.
Furthermore, ClO2against other waterborne pathogens is not documented
in literature. The objective of this study is to determine the efficacy of ClO2against Legionella, Non-Tuberculosis Mycobacterium (NTM), and
Het-erotrophic Bacteria (HB).
Methods: The study hospital had history of Legionella colonization in the water system, and L. pneumophila (sg1, sg2, sg6), L. longbeachae, and L. micdadei were isolated from various locations. A ClO2generator (@66g/h
by ProMinent Fluid Controls (Taiwan) Co., Ltd.) was installed at the cold wa-ter supply in test building. The target ClO2concentration was 0.3w 0.5 mg/
L with a high alarm set at 700mv ORP. Water samples were collected for Legionella by a standardized culture method (ISO 11731-2:2004). Results: Legionella positivity was reduced from 50%(6/12) to 0%(0/13) with 2 weeks. Legionella positivity was able to maintain at< 15% with lower con-centration of ClO2to minimize the odor. During the same period, NTM
posi-tivity was reduced from 29% (4/14) to 0% (0/38), and average HB counts were reduced from>300 cfu/L to below 30cfu/mL.
Conclusion: ClO2treatment of cold water supply could control Legionella
colo-nization in the test building, and no more nosocomial LD case was detected even Legionella positivity was not reduced to zero at a lower concentration of ClO2. Furthermore, ClO2also reduce the colonization of NTM and HB in the
same water system. ClO2 treatment provides a cost effective alternative
compared to superheat-and-flush and hyperchlorination for Legionella, and may have potential to eradicate NTM and HB in hospital water systems.
