Clean Care is Safer Care

The goal of Clean Care is Safer Care is to ensure that infection control is acknowledged universally as a solid and essential basis towards patient safety and supports the reduction of health care-associated infections and their consequences.

As a global campaign to improve hand hygiene among health-care workers, SAVE LIVES: Clean Your Hands is a major component of Clean Care is Safer Care. It advocates the need to improve and sustain hand hygiene practices of health-care workers at the right times and in the right way to help reduce the spread of potentially life-threatening infections in health-care facilities. - by WHO (World Health Organization)

Breaking the Chain of Infection


Infection can easily spread in the clinical area. You have studied that all links in the chain of infection must be connected. Therefore it is your responsibility to break the chain & prevent the spread of infection.

1. State six (6) essential factors in the chain of infection and give two (2) example for each factor.

 
An infection occurs when there are presence of a pathogen. All components of the chain must be present and intact for the infection to occur.

Components of the chain include:-
 

No

Factor

Explanation

Example

1.

Infectious agent

Pathogens – disease causing organisms

Bacteria, fungi, viruses and protozoa

2.

Reservoir

Any place an infectious agent can survive, grow or multiply

Plants, animals, soil, water, medical equipments, oxygen tubing.

Human body is the most common reservoir.

3.

Portal of exit

Path which infectious agent leaves the reservoir

Body fluids, mouth and nose, respiratory tract, skin and mucous membrane and transplacental route from mother to the unborn infant.

4.

Mode of transmission

Since microorganisms cannot travel on their own, they require a vehicle to carry them to other people and places

1. Contact – direct (person to person), indirect (object or surface), droplet
2. Airborne – longer distance over a greater time
3. Ingestion of contaminated food or water
4. Vector – living creature, insects

5.

Portal of entry

Path which infectious agent enter the host. Any opening on the body can be a portal of entry

Respiratory tract, ears, eyes, gastrointestinal tract, genitourinary tract, broken skin.

6.

Susceptible host

Any person who is at risk for infection.

Young children, elderly people, people with low immunity (due to malnutrition, genetics)


2. Explain ten (10) nursing interventions to break the chain of infection.

Nurse uses infection control practices (e.g. medical asepsis, surgical asepsis, standard precautions) to break the chain and to stop the spread of infection.
 
 
 
 


No

Nursing intervention

Rationale

1.

Educate support service personnels about appropriate methods of cleaning, disinfect and sterilize equipments and devices.

Knowledge of ways to reduce or eliminate microorganisms is a step of gaining compliance with aseptic practices.

2.

Assist patient to carry out appropriate skin and oral hygiene.

Hygiene measures reduce the numbers of microorganisms and the likelihood of infection.

3.

Change dressing and bandage when they are soiled and wet.

Moist dressing is an ideal environment for microorganisms to grow and multiply.

4.

Dispose of damp and soiled linens.

Damp and soiled linens provide an environment for microorganisms to grow.

5.

Dispose of feces and urine.

Feces and urine contain many microorganisms. Feces may also be the source of certain microorganisms such as Hep A virus.

6.

Ensure all fluid containers for example water jug, suction tube and drainage bottles are covered or capped.

Prolonged exposure incerease the risk of contamination by airborne pathogens.

7.

Empty suction tube and drainage bottles at the end of each shift or before it is full.

If it is left too long, drainage may harbour microorganisms, it will prolifarate and have the risk of transmitting to others.

8.

Avoid talking, coughing or sneezing over an open wound or sterile fields. Cover the mouth and nose when coughing and sneezing.

These will limit the number of microorganisms escape from the respiratory tract.

9.

Perform hand hygiene as per guideline.
1. Before touching a patient
2. Before clean / aseptic procedure
3. after body fluid exposure risk
4. After touching a patient
5. after touching patient surroundings
 

Hand hygiene is an important means of controlling and preventing the transmission of microorganisms.

10.

Wear mask and eye protection when in close contact with patient who has infection transmitted by droplets from the respiratory tract.

Masks and goggles provide protection from microorganisms in patient’s blood, body fluids, non-intact skin and mucous membrane.

11.

Use sterile technique for invasive procedures such as injection and catheterization.

Invasive procedure penetrate the body natural protection barriers - skin (which is the 1st line defence mechanism) to microorganisms.

12.

Use sterile technique when expressing open wound or handling dressing.

Open wound is vulnerable to microbial infection.

13.

Provide all patients with their own personal care items.

People have less resistance to another person's microorganisms than to their own.

14.

Maintain the integrity of patient’s skin and mucous membrane.

Intact skin and mucous membrane protect againts invasion by microorganisms.

15.

Ensure patient receives a balanced diet.

A balanced diet supplies proteins and vitamins necessary to build and maintain body tissues and also production of enzymes and hormones.

16.

Educate the public about the importance of immunizations.

Immunizations protect people from some infectious diseases.
