Health hazards of healthcare waste

 

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.
