PRINCIPLES IN MLS PRACTICE 1 Title of the lesson: Health Care Waste Management Date| Lecturer/Professor: December 2019 | Ma’am Maria Katrina B. Pilit, RMT Transcriber: Julia Pauline P. Husmillo OUTLINE Defining Health Care Wastes Categories of Health Care Wastes Legislation, Policies, and Guidelines Governing Health Care Wastes Health Care Waste Management System DEFINING HEALTH CARE WASTES Health care wastes refer to all solid or liquid wastes generated by any of the following activities: Diagnosis, treatment, and immunization of humans Research pertaining to diagnosis, treatment, and immunization of humans Research using laboratory animals geared towards improvement of human health Production and testing of biological products Other activities performed by a health care facility that generates waste ● All heath care facilities are tasked to ensure that there are no adverse health effects and environment consequences from: generation, segregation, collection, storage, transport, and treatment, disposal of health care wastes ● Health care waste generators - health care facilities and other spaces where health care services are offered with activities that generate wastes: Hospitals and medical centers Infirmaries Birthing homes Clinics and other health-related facilities Laboratories and research centers Drug manufacturers Institutions Mortuary and autopsy centers 2. Infectious & Pathological Wastes Infectious – contains pathogens, Pathological – tissues, organs, body parts, human fetus, and animal carcasses, blood and body fluids 3. Sharps items that can cause a cut or puncture wounds (needles, syringes, scalpels, saws, blades) considered the most dangerous waste because of its potential to cause both injury and infection 4. Pharmaceutical Wastes expired, unused, split, and contaminated pharmaceutical products, drugs, vaccines, and sera includes antineoplastic, cytotoxic, and genotoxic wastes such as drugs used in oncology or radiotherapy, and biological fluids from patients treated with the said drugs 5. Genotoxic Wastes cytostatic drugs, vomit, urine, feces from patients treated with cytostatic drugs highly hazardous and may have mutagenic (mutation), teratogenic (birth defects), or carcinogenic (cancers) properties (violet waste bin) 6. Chemical Wastes discarded chemicals (solid, liquid, or gaseous) generated during disinfection and sterilization procedures chemicals are considered hazardous when they are: toxic (with health and environment hazards) corrosive (acid of pH < 2.0 and bases of pH > 12.0) flammable (with a flash point below 60˚C) reactive (explosive with water) 7. Radioactive Wastes wastes exposed to radionuclides including radioactive diagnostic materials or radiotherapeutic materials disused sealed radiation sources, liquid, and gaseous materials contaminated with radioactivity ● ● ● ● ● ● 1. HEALTH CARE WASTE STATISTICS Estimated 16 billion injections are administered worldwide, but not all of the needles and syringes are properly disposed of afterwards According to a joint assessment of the World Health Organization (WHO) and United Nations Children’s Fund (UNICEF) – over half (58%) of the 24 countries had adequate systems for healthcare waste disposal According to WHO – 75-90% wastes are non-hazardous; 1025% of wastes are hazardous and may be infectious, toxic, or radioactive High-income countries – 0.5kg of hazardous waste/hospital bed/day Low-income countries – 0.2kg of hazardous waste/hospital bed/day CATEGORIES OF HEALTH CARE WASTES Non-hazardous/General Waste wastes that have not been in contact with communicable or infectious agents, hazardous, chemicals, or radioactive materials comes mostly from the administrative and housekeeping functions of health care establishments IMPACT OF HEALTH CARE WASTES Individuals exposed to health care wastes are more likely at risk of getting injured or infected Exposure of the general population can be mainly through chronic exposure (for prolonged periods in minute quantities) or acute exposure (for short periods in large quantities) Hazards may include drug resistant microorganisms, chronic and acute exposure to pathogens Other causes; sharp inflicted injuries, toxic exposure, chemical burns, air pollution, thermal injuries, radiation burns 1 of 4 LEGISLATION, POLICIES, AND GUIDELINES GOVERNING HEALTH CARE WASTES INTERNATIONAL AGREEMENTS PERTAINING TO HEALTH CARE WASTE MANAGEMENT 1. 2. 3. 4.

Health Care Waste Management Hierarchy Green Procurement – Prevent and Reduce Health care facilities are encouraged to avail of services that are least harmful to the environment and to purchase less polluting products Resource Procurement Reusing – either finding a new application for a used material or using the same product for the same application repeatedly Recycling – processing of used materials into new products Recovery – defined in two ways: o whereby waste is converted to fuel for generating electricity or for direct heating of premises o a term used to encompass three subsets of waste recovery: recycle, composting, and energy recovery End of Pipe – implemented when wastes are not safe for reuse, recycle, or recovery Treatment – process of changing the biological and chemical characteristics of waste to minimize its potential to cause harm Disposal – refers to discharging, depositing, placing, or releasing any healthcare waste into air, land, or water Sharps (Red bin) Chemical (Orange bin) Pharmaceutical (Blue bin) Radioactive (Yellow bin w/ radioactive sign) SEGREGATION, COLLECTION, STORAGE, AND TRANSPORT OF HEALTH CARE WASTES Healthcare facilities are tasked to ensure that generated wastes are properly and safely managed; wastes must be segregated, collected, stored, and transported The effective management of health care wastes considers the basic elements of waste minimization, identification, and segregation Proper placement, labelling, and use of color-coded plastic liners must be implemented Type of Waste Specifications Infectious (Yellow bin) Bin: Strong leak-proof with cover labelled “Infectious” with biohazard symbol General (Green or black bin) Dental (White bin) 0.009mm thickness and labelled “Infectious Waste” with a tag indicating source and weight of waste and date of collection; may or may not have biohazard symbol Bin: Strong leak-proof with cover labelled “Pathological/Anatomical” with biohazard symbol Liner: Yellow plastic that can withstand autoclaving with 0.009mm thickness and labelled “Pathological/Anatomical Waste” with a tag indicating source and weight of waste and date of collection; biohazard symbol is optional Bin: Puncture-proof with wide mouth and cover labelled “Sharps” with biohazard symbol Liner: Not applicable Bin: Labelled “Chemical Waste”; For liquid chemical waste, inside the bin is a disposal bottle made of amber-colored glass with at least 4 liter-capacity that is strong, chemical resistant, and leak-proof Liner: Yellow with black band plastic with 0.009mm thickness and labelled “Chemical Waste” with a tag indicating source and weight of waste and date of collection Bin: Strong leak-proof with cover labelled “Pharmaceutical Waste” for expired drugs and drug containers, and “Cytotoxic Waste” for cytotoxic, genotoxic, and antineoplastic waste Liner: Yellow with black band plastic with 0.009mm thickness and labelled “Pharmaceutical Waste” with a tag indicating source and weight of waste and date of collection Bin: Radiation-proof repositories, leak-proof, and lead-lined container labelled with name of radionuclide and date of deposition with radioactive symbol Liner: Orange plastic with 0.009mm thickness and labelled “Radioactive” with a tag indicating name of radionuclide and date of deposition Bin: Optional recycle symbol for recyclable non-hazardous wastes; varying sizes depending on the volume of waste Liner: Black or colorless plastic for non-biodegradable and green for biodegradable with a thickness of 0.009mm with a tag indicating source, weight of waste, and date of collection - Table 4.2. Guidelines for the proper labelling, marking, and color coding for waste segregation in healthcare facilities Liner: Yellow plastic that can withstand autoclaving with 3 of 4 TREATMENT AND DISPOSAL OF HEALTH CARE WASTES Health care wastes can be decontaminated either by: Sterilization – kills all microorganisms Disinfection – reduces the level or microorganisms present in the material Acceptable technologies and methods used in the treatment of health care wastes: 1. Pyrolysis thermal decomposition in absence of supplied molecular oxygen in the destruction chamber waste is converted to gaseous, liquid, or solid form 2. Autoclave steam sterilization, an efficient wet thermal disinfection process usual setting is at 121 ˚C with a pressure of 15 psi for 15-30 minutes 3. Microwave size reduction device shredding of wastes is done before disinfection temperature of 100 ˚C for at least 30 minutes 4. Chemical Disinfection kill or inactivate present pathogens chemicals used: 10% sodium hypochlorite (recommended), hydrogen peroxide, peroxyacetic acid and heated alkali 5. Encapsulation filling of container with waste, adding and immobilizing material and sealing to reduce the risk of scavengers gaining access to the hazardous healthcare wastes 6. Inertization mixing of waste with cement, lime, and water to minimize the risk of toxic substances contained in waste migrating into surface water or groundwater 7. Landfill engineered site (w/ secured proper permits from DENR) designed to keep waste isolated from the environment located in San Mateo, Rizal & Navotas © PowerPoint presentation of Ma’am Aurian S.
