Infection prevention and Control (IPC)

Infection prevention and control (IPC) is a practical, evidence-based approach which prevents health workers and patients from being harmed by avoidable infection and as a result of antimicrobial resistance.

3. Infection Prevention 3
Sources of Infection
What are the common sources of infection?
•Environment : Blood, body fluids, secretions,
excretions, placenta, contaminated sharps and
other equipments.
•Other clients & Attendants
•People in the community
•Health care delivery personnel

4. Infection Prevention 4
Why is infection prevention important?
To prevent the occurrence of
infections and to minimize the risk of
transmitting any infections including
hepatitis B, C and HIV to clients,
health care staff and community.

5. Infection Prevention 5
Principles of Infection Prevention
•All objects in contact with the client:
Potentially contaminated
•Every person: Potentially infectious
•If an object is disposable: Discard as waste.
•If reusable: Prevent infection by
decontamination cleaning, disinfecting or
sterilizing

6. Infection Prevention 6
Standard Precautions
1.Hand washing
2.Use of protective attire
3.Processing of used items
4.Proper handling and disposal of sharps
5.Maintaining a clean environment
6.Biomedical waste disposal

2. Standard Precautions: Protective attire
•Gloves
•Masks
•Eye-covers
•Gowns
•Caps
•Footwear

10. Infection Prevention 10
3. Standard Precautions: Processing of used items
A. Decontamination
B.Cleaning
C.Sterilization or high level disinfection (HLD)
D. Storage

11. Infection Prevention 11
Processing of used items
A. Decontamination:
Preparation of Bleaching solution (0.5%)
•Wear utility gloves and plastic apron.
•Take 1 litre of water in plastic bucket.
•Make thick paste with 3 levelled tea spoons of
bleaching powder and water in a plastic mug.
•Mix paste in the bucket of water to make 0.5 %
chlorine solution.

12. Infection Prevention 12
Processing of used items
B. Cleaning:
•Involves -scrubbing with a brush,
detergent and water.
•Detergent is important for effective
cleaning because water alone does not
remove proteins, oils and grease.

13. Infection Prevention 13
Processing of used items
C. Sterilization:
Sterilization ensures that items are free of all
microorganisms (bacteria, viruses, fungi and
parasite) including endospores.
Three methods of sterilisation:
•Steam sterilisation / Autoclaving / Pressure cooker
autoclaving
•Dry heat sterilisation
•Chemical / cold sterilisation

14. Infection Prevention 14
Processing of used items
Pressure cooker type autoclave
C. Sterilization:
Geared steam gauge Excess pressure relief valve
Control Valve
Air exhaust tube
Top Handle

15. Infection Prevention 15
Processing of used items
High level Disinfection
•HLD eliminates bacteria, viruses, fungi and
parasites, but does not kill all endospores which
cause diseases such as tetanus and gas gangrene.
•HLD only acceptable alternative to sterilisation.
•There are 3 methods of HLD:
–Boiling
–Chemical HLD
–Steaming
C. Sterilization:

16. Infection Prevention 16
D. Storage:
•To prevent contamination after processing
•Do not store instruments or other items
such as scalpel blades and suture needles
in solution, always store them dry
Processing of used items

17. Infection Prevention 17
4. Standard Precautions:
Proper Handling and Disposal of sharps
Needles and syringes
•Use disposable needle and syringe ONLY ONCE.
•Always wear utility gloves while handling sharps
•Do not disassemble the needle and syringe after use.
•Do not recap, bend or break needles before disposal.
•Make needles unusable after single use by burning them
in a needle destroyer
•Never burn syringes

18. Infection Prevention 18
•Dispose off needles and syringes in a puncture-proof
container such as metal box, cardboard box or an empty
plastic box.
•Finally dispose as follows:
(i)Dispose the needles and broken vials in pit / tank,
(ii)Send the syringes and unbroken vials for
recycling or landfill
4. Standard Precautions:
Proper Handling and Disposal of sharps
Needles and syringes

19. Infection Prevention 19
5. Standard Precautions:
Maintaining clean environment
For cleaning areas –operation theatres,
procedure rooms , latrines
Disinfectant cleaning solution
To clean up spills of blood or other
body fluids
Disinfectant
0.5 % chlorine solution
To remove dirt & organic material such
as grease, oil
Plain detergent and water
UsesType of cleaning solution

20. Infection Prevention 20
6. Standard Precautions:
Biomedical Waste Disposal
It is the waste that is generated during diagnosis, treatment
or immunization of human beings
Purpose of waste disposal
•Minimize/Prevent the spread of infection to hospital
personnel who handle waste
•Prevent the spread of infection to the local community

D. Treatment and Disposal
Do’s
•Disinfect and destroy the waste before its final disposal.
•Remember
–Biological waste to be buried deep at the sub-centre
–Syringes to be cut with hub cutters and chemically
disinfected at source of generation before final disposal
into sharps pit located at the PHC

26. Infection Prevention 26
Key Messages
•Hand-washingis essential for preventing
infections
•Always wear glovesespecially where there is a risk
of touching blood, body fluids, secretions,
excretions or contaminated items
•Decontamination : 0.5% bleach solution is the
least expensive and the most rapid acting and
effective agent to use for decontamination
•Proper handling of contaminated waste
minimizes the spread of infection to healthcare
personnel and to the local community

27. Infection Prevention 27
Key Messages
Proper handlingmeans:
•Wearing utility gloves
•Transporting solid contaminated waste to the
disposal site in covered containers
•Disposing of all sharp items in puncture-resistant
containers
•Carefully pouring liquid waste down a drain or
flushable toilet
•Burning or burying contaminated solid waste
•Washing containers, gloves and hands after
disposal of infectious waste
