1
INFECTION CONTROL GENERAL CONCEPTS
  • Data collected presented by
  • Dr. Mohamed ElBashaar

2
General Infection Control topics
  • Standard precautions.
  • Hand Hygiene.
  • Transmission based precautions (Isolation
    precautions).
  • Use of PPE.
  • Waste Management.

3
Standard Precautions
  • Applied to Blood, Blood Products, Body fluids
    and Excreta
  • To avoid exposure to blood - borne pathogens
    (e.g. HBV, HCV HIV)

4
Standard Precautions
  • Apply standard precautions to all patients
    regardless of their diagnosis, and
  • to all contaminated equipments and materials.
  • Use judgment in determining which protective

    ,use the Scoop method (one hand method).

7
USING SCOOP METHOD

  • 4) CLEANING SPILLS (e.g. Blood body fluids)
  • Wear gloves and other PPE
  • Absorb Wipe up the spill with an absorbent
    towel.Clean with detergent.
  • Apply disinfectant to the contaminated area

Transmission-Based Precautions
  • Used in addition to Standard Precautions for
    Specified Patients
  • Designed for the Care of Patients known or
    suspected to be infected by epidemiologically
    important pathogens spread by airborne,
    droplet, or contact transmission.

19
Airborne Precautions
  • For infectious agents with droplet nuclei lt 5
    microns
  • Examples
  • Tuberculosis
  • (diagnosed or suspected)
  • Measles
  • Chickenpox (varicella)
  • Precaution Details
  • Isolation rooms under negative pressure
  • Air cycling gt12/hour
  • HEPA filters
  • Use respirators or N95 mask.
  • Patient will use a surgical mask

20
  • Health care worker wearing a personal

  • Influenza.
  • Meningococcus meningitis.
  • Precaution Details
  • Private room
  • Surgical Mask if within 1 meter of patient.

23
Contact Precautions
  • For protection against skin-to-skin contact and
    physical transfer of microorganisms to a host
    from a source e.g.
  • Discharging wound
  • MRSA
  • VRE
  • Precaution Details
  • Private room
  • Handwashing
  • Glove changes

24
For effective segregation of waste, provision of
