Medical Waste Management during COVID-19 Pandemic: A Study of Sukraraj Tropical & Infectious Disease Hospital and Bir Hospital Presented by: Ojeshwi Risal Human and Natural Resources Studies Department of Development Studies Kathmandu University, School of Arts Background Waste (also known as rubbish, trash, refuse, garbage, junk, litter) is unwanted or useless materials. According to the (World Health Organization, 2018) , health care waste is generated by institutions such as hospitals, health centers, medical research institutes, pharmaceutical manufacturing plants, pharmacies, blood banks, and home health care activities. ● Health facilities and diagnostic procedures generate two categories of garbage: general trash and hazardous waste. ● The garbage generated by healthcare operations is classified as general waste in 85 percent of cases, while the rest is classified as hazardous waste in cases when it is contagious, toxic, or radioactive. Each year, 274 hospitals in Nepal generate a total of 10,520 tonnes of non-hazardous healthcare waste and 3,094 tonnes of hazardous medical waste. (UNDP, 2017). ● ● The COVID-19 pandemic has caused an increase in medical waste and viral transmission, requiring modern treatment techniques to reduce risk to healthcare personnel, trash handlers, and others. ● COVID-19 virus transmits largely by droplets of saliva or nasal discharge when an infected person coughs or sneezes, according to the World Health Organization. ● Waste management systems failed very quickly as a result of the coronavirus disease 2019 (COVID19). Statement of Problem ● The study’s goal is to examine how well healthcare institutions handle trash while providing data that may be used to these facilities effective management of medical waste. ● The health institutions in Nepal are working hard to achieve high standards in the treatment of medical waste, but their efforts are being hampered by limited resources and insufficient skills. ● According to the report published by MOHP, health care institutions in Nepal produced approx 20,18,450 Kilograms of health care risk waste annually (assuming 0.5 kg per patient per day) in 2001 (MOH 2003). Objective of the research The main objective is to understand the current practices of medical waste management in two hospitals of Kathmandu Valley, namely Sukraraj Tropical & Infectious Disease Hospital and Bir Hospital 201 MoH The specific objectives of the study are outlined below: Cina ● To study the present methods of hospital waste management. ● To identify the challenges of medical waste management among the selected hospital during COVID-19 ● To explore the consequences, especially the environmental risks associated with medical waste. Research Questions General Question How Sukraraj Tropical & Infectious Disease Hospital and Bir Hospital manage the medical waste? Specific Questions i. What are the present methods of minimization, segregation, collection, storage, treatment, and disposal of hospital waste? ii. What are the challenges among the selected hospital during COVID-19? iii. What are the environmental risks associated with medical waste? Rationale / Justification of the study 2001 The problem of Health Care Worker disposal in the hospitals and other healthcare MH establishments has become an issue of increasing concern, prompting hospital administration to seek new ways of scientific, safe and cost-effective management of the waste, and keeping their personnel informed about the advances in this area. The need for a proper health care waste management system is of prime importance and is an essential component of quality assurance in hospitals. Limitations of the research 1 The study solely focuses on solid medical wastes only. 2 3 The number of incoming patients in the hospital fluctuates but the bed remains constant. This study assumes that all the beds present in the hospital are occupied. The study examines and characterizes medical wastes from the selected hospitals as a whole, not from different departments of the hospitals. Literature Review In the eighteenth century, nothing was understood about sanitation or how to properly dispose of medical waste around the world. Lister found in the 1870s that the fast spread of illness in hospitals was due to a lack of effective 2001 cleanliness and medical waste disposal processes. (Gregory & Tulchinsky, n.d.) MH The COVID-19 pandemic has placed a great deal of pressure on healthcare systems worldwide, including the management of medical waste. The literature review found that both Sukraraj Tropical & Infectious Disease Hospital and Bir Hospital have implemented measures to properly manage medical waste during the COVID-19 pandemic. Literature review also provides valuable insights into the medical waste management practices in Nepal during the COVID-19 pandemic and can serve as a useful reference for other healthcare facilities facing similar challenges.

Hospital Waste Disposal : 36k Earnings from recyclable items:30K C O S T Challenges for managing the health care waste during COVID-19 - During the peak of the COVID-19 pandemic, hospitals across the world became centers of attention. COVID-19 can contaminate objects and wastes, presenting a health risk if not managed effectively. One of the measures to fight COVID-19 was the use of face masks and PPE. Checklist to Manage COVID-19 waste management Bir Hospital - PPE should be worn all time while handling and transporting waste from designated area to Personal Protective Earnings from recyclable items : 40k treatment zone. Equipment Staff should select appropriate PPE to prevent risk of infection and overuse of PPE - Waste minimization Waste Reduction at source Preference to recyclable and reusable items Use separate color-coded containers/bins to discard Sukraraj Tropical & Infectious Disease generated waste.

Waste treatment - Treat the waste with Autoclave, Friction Heat system or any other waste treatment technology Treat for 60 minutes at 121 to 135 degree Celsius Sukraraj Tropical & Infectious Disease If treatment zone is not available within healthcare Hospital Waste Disposal: facility 36k coordinate with waste treatment provider Earning from recyclable item: 30k Waste disposal Treated waste can be discarded as regular waste. Norvic. I. Hospital Waste Disposal : 36k disinfect if PPE is reusable. Earnings from recyclable items:30K Safely remove PPE and dispose if it is non- reusable and Discussion ● ● ● ● ● Both hospitals have implemented training programs for healthcare workers to ensure that they understand the proper methods of handling and disposing of medical waste. The results also say that these hospitals have taken appropriate steps to ensure the safe and effective management of medical waste during the pandemic. However, ongoing monitoring and assessment of these practices are necessary to ensure their continued effectiveness and to identify any areas for improvement. Considering the global transmission of COVID-19, excessive biomedical waste has become a new major threat to public health as well as to the environment during this pandemic. (WHO, 2020) For instance, in August 2021, scientists discovered a fish trapped in a medical latex glove during a canal cleanup in the Dutch city of Leiden, prompting them to investigate whether there was a broader problem. Environmental Risk ● ● ● ● ● Improper incineration and disposal of hazardous waste can pollute air, water and soil. Open collection and disposal of hazardous waste may cause air borne contamination and hence increase air borne infection. The leftover ash when buried can leak into the ground resulting in both soil pollution and groundwater contamination. Improperly treated waste into the landfill or river system can damage aquatic life and spread water borne infection like cholera, typhoid, hepatitis, and so on. Hospital waste into the virgin soil may transfer drug resistant characteristic into the normal bacteria PHOTOS OF BIR HOSPITAL & TEKU HOSPITAL Photos of Respondents CONCLUSION ● COVID-19 has caused a significant increase in medical waste production. ● Both the hospitals reduce risk of cross-contamination and disease transmission through proper waste separation, record-keeping, and safe disposal. ● The COVID-19 epidemic has exposed the flaws in the healthcare waste management system and the urgent need for change. ● Develop better waste management methods to ensure safety of healthcare staff, patients, waste handlers, and environment. ● The COVID-19 pandemic has highlighted the shortcomings of the healthcare waste management system, but the experiences of Bir Hospital and Sukraraj Tropical & Infectious Disease Hospital demonstrate that medical waste may be managed in a way that protects public health and the environment.
