Containers are not tightly closed and the MSW is put too much and above the specified line • In surveyed hospitals, the collection, transportation of MSW is mainly done by manual methods (eg hand trolleys or wheeled containers) to transport MSW, which resulting many risks for participants; Specifically, except for the Transportation Hospital which is equipped with microwave treatment, the remaining hospitals mainly have applied the CHUWASTAR ovens which are incinerator technology to treat MSW, however, HMSW incinerators of some hospitals in the city have degraded, affecting the quality of treatment; • Among questioned participants, 86.7% of them were aware of Regulation medical waste management on Joint Circular No 58/2015 / TTLT-BYT-BTNMT Besides, the awareness of medical staff about the color codes for medical waste containers was still low and only 46.7% instructed the patient about the color code of the garbage containers Only 26.7% of interviewed patient and patient's family member was aware of the waste management regulations of the Ministry of Health and the Ministry of Natural Resources and Environment, 20% discerned the color code of the waste container Raising people awareness is one of the most necessary activities for all healthcare facilities in Yen Bai city to improve MSWM In conclusion, investing in education and propaganda to raise people awareness are the suggested effective solutions In addition, hospitals should spend on equipment to improve MSWM (eg collection and transportation tools, storage area, etc), and use non-burning technology instead of degraded incinerators 44 5.2 Recommendations The thesis gave an overview of the current status and proposed management solutions for HMSW in Yen Bai's healthcare facilities To better work on MSWM in Yen Bai City, the author recommends: • Application of the 3R model (Reduce - Reuse - Recycle) in all health-care facilities: Reduce the volume of MSW through lifestyle changes and usage habits, improving production processes, using eco-friendly products, etc Reuse and recycle things that are usable according to the law norms; • Invest more equipment for waste collection, storage, and treatment to ensure environmental sanitation; Equipment systems need to set logically in each department to avoid confusion when separate MSW, waste bin needs to appropriate for each type of waste (color-code, symbol, etc) • Improving the awareness and education of medical staffs as well as patient and family member on medical solid waste management And, enhancing the management of the waste manager in each health-care facilities; • Inviting businesses, investors and organizations inside and outside the country to invest in hospitals to more effective medical solid waste management; • The municipal corporations need to make stringent laws and ensure its compliance by both the hospital management and its staff.; Finally, to take a reasonable and comprehensive solution for environmental sanitation, it needs to have deeper research and constantly to have the reviews, catch the things to change so that further improves the models of MSWM 45 REFERENCES REFERENCES Bach, D V (2018) Overview of Yen Bai province Yen Bai Chartier, Yves, Emmanuel, Jorge, Pieper, Ute World Health Organization (2014) Safe management of waste from healthcare activities Switzerland Department of Natural Resources and Environment of Yen Bai province (2015) Report on the status of environmental in Yen Bai province (2011-2015) Yen Bai Hang, N (2012) Situation and solutions for waste management in the health sector Ha Noi Hoang, M (2015) Strengthening grassroots health, ensuring basic health care for people Ha Noi Ly, P T (2016) Towards the selection of environmentally friendly medical waste treatment technologies, Ha Noi Mankolli, H (2013) Hospital Solid Wastes and Its Effect on Environment, Albania Michelle (2014) Medical Waste: Challenges Faced Around the World Retrieved from:http://www.globalization101.org/medical-waste-challenges-faced-aroundthe-world-2/ Miller, R.K and Rupnow, M E (2016) Survey on medical waste management and Future Technology Surveys Georgia Minister of Health (2007) REGULATION ON MANAGEMENT OF MEDICAL WASTE - Promulgated in conjunction with Decision No 43/2007 / QD-BYT Ha Noi Ministry of Health and Ministry of Natural Resources and Environment (2015) Joint Circular No 58/2015 / TTLT-BYT-BTNMT Ha Noi 46 Ministry of Natural Resources and Environment (2011) Circular No 12/2011 / TTBTNMT Ha Noi People's Committee of Yen Bai province (2016) Decision No 1433 / QD-UBND promulgating the plan for collection, transportation, and treatment of hazardous medical waste in Yen Bai province Yen Bai Quy, V (2011) Some environmental and global issues in Viet Nam Ha Noi Sang, L M (2016) Experience in some countries around the world in medical waste management Ha Noi Sushma Rudraswamy, M.D.S (2013) Global scenario of Hospital waste management India Tap, V H (2016) Impact of medical waste on the environment Ha Noi Trang V T H (2016), Patterns of solid waste management in Yen baI province, Yen Bai WHO (2010) Safe management of wastes from healthcare activities Geneva Yen Bai Portal (2016) Overview of yen yai province Retrieved from: http://yenbai.gov.vn/Pages/Gioi-Thieu-Chung.aspx Zafar, S (2018) Medical Waste Management in Developing Countries Oman 47 APPENDIX Survey questionnaire for medical staff RESEARCH: ASSESSMENT OF HAZARDOUS MEDICAL WASTE MANAGEMENT IN YEN BAI CITY - YEN BAI PROVINCE Researcher: Pham Thi Huyen Date: Please put a check mark (√) in a box □ which corresponds to your answe Part 1: Personal background Name: Age: Gender: Group: Part 2: Level of awareness on HMWM Do you have guidelines for the regulation of HMWM issued by the Ministry of Health? □ Yes □ No If you had, who guided you? □ Hospital □ Yen Bai Department of Health □ Urban Environmental Company 48 □ Others What is the current regulation on medical waste management in hospitals/clinics? □ Decision No 2575/1999 / QD-BYT of August 27, 1999 of the Minister of Health promulgating the Regulation on management of medical wastes □ Decision No 43/2007 / QD-BYT dated 30 November 2007 of the Minister of Health promulgating the regulation on management of medical waste;
