However, maintaining a sustained high-quality potable water is a core component of safe health care provision. The aim of the study is to report the effective use of quality improvement tool to overcome a contami- nated potable water in specialised oncology and organ transplant hospital. Methods: Infection Prevention and Control (IPC) department was challenged with high Colony Forming Unit (CFU) count in potable water. Therefore, a multidisciplinary team was formed and com- posed of IPC, engineering maintenance department, laboratory services, nursing services, and environmental consultant from another facility. Plan, Do, Check, Act (PDCA) quality improvement tool was used to resolve this issue. In the planning phase, “5 whys” approach was also used to draw the root map and sketch- ing out reversing actions, additionally revision of current policy and procedure was conducted according to World Health Organi- zation (WHO) standards. Daily chlorine testing, monitoring cleaning of water supply system, weekly testing of the level of bacterial and other substances in water, and temporary restriction of water utilization for patients and workers in selected areas were insti- gated in the hospital. Moreover, more chlorine pumps were installed at the source and regular flushing of supply system were con- ducted. Finally, extensive implementation of a modified action plan was conducted all over the hospital and effectiveness of these actions was evaluated. Results: a progressive decline was noticed in CFU count in potable water over two months till it reaches the lowest number (<50 CFUs) and maintained throughout the year. Conclusions: Using quality improvement tools is an effective ap- proach to identify factors contributing to the contamination of potable water, as well as in drawing the roadmap to rectify this issue. This cannot be achieved without the collaboration of a multidisciplinary team and leadership support. Session EOC-092 WITHDRAWN Healthcare Worker Safety/ Occupational Health Session WSOH-093 12:30-1:30 p.m. Bacterial Colonization of Mobile Phone Carried by Health-Care Providers: A Cross- Sectional Study in a Tertiary Care Teaching Hospital Siriluk Apivanich, RN, Instructor, 270 Faculty of Medicine, Ramathibodi Hospital, Rama 6 road ratchatewi, Bangkok 10400, Thailand; Kumthorn Malathum, Assistant Professor of Medicine, Instructor, Ramathibodi Hospital; Wonnapha Prapaipanich, Instructor, Ramathibodi hospital; Thanomvong Muntajit, RN, ICN, Ramathibodi hospital; Suntariya Sirichot, RN, ICN, Ramathibodi hospital; Thipakorn Pornmee, RN, ICN, Ramathibodi hospital BACKGROUND: Mobile phones of healthcare workers (HCWS) could be colonized by bacteria pathogens. They may act as reservoir or vectors for transmission of microorganisms to patient with indi- rect contact. The aim of this cross- sectional study is to evaluate the bacteria contamination of mobile phones used by HCWs in a ter- tiary care teaching hospital. METHODS: 173 samples mobile phones (MPs) from nurses, physi- cians, and medical students were screened for microbial contamination during October 4 - November 24, 2015. Sampling col- lected 2 times from each mobile phone, total of 346 samples. There were swab culture before and after cleaning the mobile phone with disinfecting wipe. Microbiological cultures were taken from MPs at the end of day shift, were randomly selected by researcher from Pe- diatric, Surgery and Medicine departments. Each Informed consent and questionnaire was signed by all the participants. A samples were proceeded according to standard guidelines. RESULTS: Of 173 mobile phones, there were 28 keypad and 145 touch- screen phones. About half of samples (52.02 %) were nurses, 30.06% were physicians, and 17.92% were medical students. The most of HCWs used the MPs many times a day while attending pa- tients, 54% of participants reported never washing their hands before using MPs. The rate of bacterial contamination of MPs was 100%. Coagulase- negative staphylococcus (45.15%) was the most frequen- cy isolated bacteria, followed by pathogenic bacteria 3-27% (Pseudomonas spp., Staphylococcus aureus, Acinetobacter spp.and Acinetobacter baumannii). After cleaning the MPs with disinfect- ing wipe. There was significant reduction in the mean number of colony-forming units after decontamination (p < .001) CONCLUSIONS: The MPs can act as reservoirs of both pathogenic and nonpathogenic organisms. Transmission of pathogens can be reduced by hand hygiene and regular cleaning of MPs.
