NEET PG High-Yield: Health Hazards of Healthcare Waste (HCW)
Improper management of healthcare waste poses significant risks to healthcare workers, patients, waste handlers, and the community.
Primary Categories of Risk
| Hazard Type | Associated Risks/Agents |
|---|---|
| Infectious Risk | Needlestick injuries leading to HIV, Hepatitis B, and Hepatitis C transmission. |
| Genotoxic/Chemical | Cytotoxic drugs, disinfectants, and solvents can be mutagenic, teratogenic, or carcinogenic. |
| Radioactive | Exposure to diagnostic/therapeutic isotopes leads to localized tissue damage or systemic toxicity. |
Transmission Routes
- Percutaneous: Through sharp injuries (needles, scalpels, glass).
- Mucocutaneous: Contact with skin or mucous membranes via splashes.
- Inhalation/Ingestion: Through aerosolized pathogens or contaminated food/water (often via scavenging).
High-Yield NEET PG Pearls:
- Scavenging: Re-use of discarded medical items (e.g., syringes) by scavengers is a significant public health danger in low-resource settings.
- Dioxins & Furans: Produced during the incineration of chlorinated plastics (PVC); these are highly toxic and persistent environmental pollutants.
- Universal Precautions: The cornerstone of prevention; treat all blood and body fluids as potentially infectious.
