  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 allpatients regardless of their diagnosis, and • to all contaminated equipments and materials. • Use judgment in determining which protective barriers are necessary.

  5. Standard Precautions • Hands Hygiene • Use Personal protectiveequipments (PPE) • Gloves • Gowns • Masks • Eye protection • Face Shields

  7. USING “ SCOOP METHOD’’

  8. 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 using sodium hypochlorite( Clorox 1: 10= 1 volume+9 water volumes) contact time 5-10min. • Absorb Clorox and wash with water.

  9. Hand Hygiene • Hand washing • Alcohol-based Hand Rub • Use of gloves does NOT replace hand washing. • Gloves must be changed in-between patients.

  10. HAND WASHING • When to wash your hands : • If hands are visibly dirty . • Soiled hands with blood or body fluids. • After contactwith: blood ,body fluids, secretions or mucus membranes.

  15. Standard Precautions

  16. Means of TransmissionFive Main Routes • Common Vehicle (Food, blood) • Vector-borne • Droplet • Airborne • Contact • Direct Contact • Indirect Contact (Objects)

  17. 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.

  18. Airborne Precautions • For infectious agents with droplet nuclei < 5 microns • Examples: • Tuberculosis (diagnosed or suspected) • Measles • Chickenpox (varicella) • Precaution Details: • Isolation rooms under negative pressure • Air cycling >12/hour • HEPA filters • Use respirators or N95mask. • Patient will use a surgical mask

  19. Health care worker wearing a personal respirator

  20. TB patient wearing a surgical mask

  21. Droplet Precautions • For infectious agents with droplet nuclei > 5 microns, through cough or sneezing: • Examples: • Pertussis • Influenza. • Meningococcus meningitis. • Precaution Details: • Private room • Surgical Mask if within 1 meter of patient.

  22. 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

  23. For effective segregation of waste, provision of different types of waste containers in all clinical areas, is necessary. BIOHAZARD BIOHAZARD SHARPS & NEEDLES Sharps Container Infectious Waste Bin Regular Waste Bin

  24. Sharps containers • Should be easily accessible • At or below the level of the eyes • Kept away from the pathways • Not to be kept on the grounds. • Should Not be overfilled more than 3/4 full. • Never to be shake to get more space
