Study Notes
Prayer Before Class
- A prayer is offered before class, invoking the Holy Spirit.
- The prayer requests guidance and wisdom for understanding, learning, and expressing oneself.
- The prayer is offered through Jesus Christ, and seeks successful completion of the work.
- The prayer ends with "Amen."
Unit 6: Healthcare Waste Management
- This unit covers healthcare waste management within the Principles of Medical Technology Practice 1.
- Key topics include definitions, classifications, and management systems for healthcare wastes.
Outline
- Part I: Focuses on healthcare wastes, including definitions, categories, and impacts.
- Part II: Covers healthcare waste management systems, including reuse, recovery, recycling, and relevant legal issues and regulatory agencies.
Learning Outcome
- Students must be able to classify biomedical and hazardous wastes.
- Students must be able to explain proper healthcare waste management processes.
Healthcare Wastes
- 75-90% of wastes produced in healthcare settings are non-hazardous.
- 10-25% of healthcare wastes are considered hazardous and could be infectious, toxic, or radioactive.
- High-income countries generate higher volumes of healthcare waste (0.5 kg/bed/day).
- Low-income countries generate lower volumes (0.2 kg/bed/day), and proper segregation of hazardous and non-hazardous wastes is often less well-implemented.
Healthcare Waste Generators
- Category 1: Hospitals and medical centers, infirmaries, birthing homes
-
Category 2: Clinics and other health-related facilities
- Medical, ambulatory, dialysis, healthcare centers & dispensaries, surgical, alternative medicine, dental, veterinary
-
Category 3: Laboratories & research centers
- Medical & biomedical labs, medical research centers, blood banks and blood collection services, dental prosthetic labs, nuclear medicine labs, biotechnology labs, animal research & testing labs, HIV testing labs
-
Category 4: Drug manufacturers, institutions
- Drug rehabilitation centers, training centers for embalmers, medical technology internship training centers, medical schools, schools of radiologic technology, nursing homes, dental schools
- Category 5: Mortuary & autopsy centers
Categories of Healthcare Wastes
- Hazardous: Sharps, infectious, pathological, anatomical, pharmaceutical, genotoxic, chemical, radioactive, pressurized containers
- Non-Hazardous (General): Recyclable, biodegradable, residual materials
Infectious Waste
- Infectious waste contains pathogens potentially harmful to susceptible hosts.
- Examples include cultures and stocks of pathogens from labs, wastes from surgical procedures or autopsies on infected patients, wastes from isolation wards, or wastes from infected patients undergoing hemodialysis.
- Also includes infected animals from research labs or materials that have had contact with infected individuals/animals.
Pathological and Anatomical Waste
- Pathological waste includes tissues, fluids, or organs from biopsies, autopsies, or surgeries.
- Special anatomical waste refers to recognizable body parts from procedures like amputations.
- An example includes internal organs for histopathological examination.
Sharps
- Sharps are waste items that can cause cuts, pricks, or puncture wounds.
- This is the most dangerous healthcare waste due to injury causing potential.
- Examples include needles, syringes, scalpels, saws, blades, broken glass, and knives.
Chemical Waste
- Chemical waste comes from discarded solids, liquids, and gases used in diagnostics/experiments or for cleaning/housekeeping.
- Examples include lab reagents, X-ray film developing solutions, disinfectants/soaking solutions, used batteries, concentrated ammonia, peroxide, chlorine, and mercury.
- Hazardous chemical wastes may have toxic, corrosive, flammable, or reactive properties, which lead to potential health and environmental risks.
Pharmaceutical Waste
- Pharmaceutical waste comprises expired, contaminated, or split pharmaceutical products, drugs, vaccines, or sera.
- Examples include bottles, vials, boxes, residue, gloves, masks, and tubing used to handle pharmaceuticals.
Genotoxic and Cytotoxic Waste
- Highly hazardous waste with mutagenic, teratogenic, or carcinogenic properties
- Examples are urine, feces, vomit potentially contaminated with cytotoxic drugs/their metabolites or antineoplastic/cytotoxic drugs.
Radioactive Waste
- Radioactive waste contains radionuclides, like radioactive diagnostic materials or radiotherapy material residues.
- Contains liquids, gases, and contaminated solids emitting ionizing radiations harmful to the environment.
- Examples include cobalt, technetium, iodine, irradiated blood products, contaminated wastes within 48 hours of contact with radionuclides
Non-Hazardous or General Waste
- This waste poses no contamination risk from infectious agents, hazardous chemicals, or radioactivity.
- It does not pose a threat to health or the environment.
- Examples include recyclable waste, biodegradable materials (kitchen waste from patient meals, leftover food waste, flowers, garden waste that can be composted).
- It also encompasses any residual waste that doesn't meet the other classification criteria.
Recyclable General Waste
- Recyclable waste includes paper products, aluminium, plastics, glass, and wood materials.
Biodegradable General Waste
- Examples encompass kitchen waste (food scraps), patient leftover foods (items with non-communicable diseases), flowers, and garden waste (compost friendly).
Impact of Healthcare Wastes
- Staff, patients, and visitors of healthcare facilities may face health risks due to healthcare wastes' improper handling.
- Waste disposal in environmentally unsound ways can also negatively affect the larger population.
Adverse Health Outcomes
- Injuries from sharps and toxic exposures from chemicals and pharmaceuticals are potential adverse health outcomes.
- Improper waste disposal methods could contribute to environmental and health problems.
- Alternatives to incineration, like autoclaving, microwaving, or steam treatment, are safer disposal methods.
Benefits of Proper Healthcare Waste Management
- Protecting patients, health workers, and the general population.
- Increasing environmental protection and worldwide efforts.
- Preventing long-term liabilities for healthcare institutions
- Adherence to healthcare guidelines and laws regarding waste management.
Assignment
- Students need to answer specific pages from a textbook ("Principles of Medical Laboratory Science 1" by Benitez).
- The deadline for submission is November 26, 2024, at 12:00 noon.
References
- Included for citation. (List of authors, titles, publisher, and links)
