Patient may acquire infection before admission to the hospital = Community acquired infection.
Patient may get infected inside the hospital = Nosocomial infection.(HAI)
It includes infections not present nor incubating at admission, infections that appear more than 48 hours after
admission, those acquired in the hospital but appear after
discharge also occupational infections among staff.
THE RISK OF INFECTION IS ALWAYS PRESENT IN EVERY HOSPITAL

FREQUENCY OF NOSOCOMIAL INFECTION
Nosocomial infections occur worldwide.
The incidence is about 5-8% of hospitalized patients, 1/3 of which is preventable.
The highest frequencies are in East Mediterranean and South-East Asia.
A high frequency of N.I. is evidence of poor quality health service delivered.

WHAT IS INFECTION CONTROL?
Infection control is a term used that describes ways we can prevent the spread of infection.
![Page 8: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/8.jpg)
Infections can causepain, suffering and often, permanent scarring.
In the worst cases, death can occur. Infections cause extra days in the hospital and
lead to higher costs for patients and their families.
Why is infection controlimportant in health care?

Dr.T.V.Rao MD 11
GOALS FOR INFECTION CONTROL AND HOSPITAL EPIDEMIOLOGY
There are three principal goals for hospital infection control and prevention programs:
1. Protect the patients2. Protect the health care workers, visitors,
and others in the healthcare environment.3. Accomplish the previous two goals in a cost
effective and cost efficient manner, whenever possible.

SCOPE OF INFECTION CONTROL
Aiming at preventing spread of infection:
Standard precautions: these measures must be applied during every patient care, during exposure to any potentially infected material or body fluids as blood and others.
Components: A. Hand washing. B. Barrier precautions. C. Sharp disposal. D. Handling of contaminated material.
![Page 17: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/17.jpg)
![Page 18: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/18.jpg)
HAND HYGIENE
Use of water and antimicrobial soap (germ killing soap) and washing for at least 15 seconds.
Use of an alcohol based hand rub
![Page 19: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/19.jpg)
When should you perform hand hygiene? Before having direct patient contact Before wearing sterile gloves and inserting a central venous
catheter Before inserting urinary catheters, peripheral vascular
catheters (IVs), or other invasive devices After contact with a patient’s intact skin such as taking a
blood pressure or lifting a patient After contact with body fluids, excretions, mucous
membranes, nonintact skin, and wound dressings If moving from a contaminated body site to a clean-body site After contact with objects in the immediate area of the
patient (such as medical equipment) After removing gloves
![Page 20: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/20.jpg)
Dr.T.V.Rao MD 20
Model good hand washing/hand hygiene practices
˙ Encourage others to do the same
˙ Maintain hand hygiene supplies for your area
˙ Maintain soap and paper products for your area
MAKE OUR HOSPITAL A MODEL FOR HAND WASHING
![Page 21: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/21.jpg)
Hand washing – areas missed
Taylor (1978) identified that 89% of the hand surface was missed and that the areas of the hands most often missed were the finger-tips, finger-webs, the palms and the thumbs.
![Page 22: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/22.jpg)
Personal protective equipment
PPE when contamination or splashing with blood or body fluids is anticipated
Disposable gloves Plastic aprons Face masks Safety glasses, goggles, visors Head protection Foot protection Fluid repellent gowns (May, 2000)
![Page 23: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/23.jpg)
Sharps injuries Prevention
correct disposal in appropriate container
avoid re-sheathing needleavoid removing needlediscard syringes as single unitavoid over-filling sharps container
Management follow local policy for sharps injury
![Page 24: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/24.jpg)
Aseptic technique
Sepsis - harmful infection by bacteria Asepsis - prevention of sepsis Minimise risk of introducing pathogenic
micro-organisms into susceptible sites Prevent transfer of potential pathogens
from contaminated site to other sites, patients or staff
Follow local policy
![Page 25: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/25.jpg)
ISOLATION
Another way to prevent the spread of infectious disease is to place the infectious patient on special precautions or “isolation”. The type of precautions depends upon how the infection is spread.
![Page 26: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/26.jpg)
What are Contact Precautions?
Contact Precautions are used to prevent infections spread by touching an infected or
contaminated body site (direct contact) or by handling objects in the environment that are
contaminated (indirect contact). Gastrointestinal (GI) infections such as rotavirus and
antibiotic resistant germs such as Oxacillin Resistant Staphylococcus aureus (ORSA)can be spread this way.
Gowns and gloves will be needed if providing direct care.
![Page 27: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/27.jpg)
What are Droplet Precautions?
Droplet Precautions are used when a patient has a disease spread by respiratory droplets.
The infectious droplets are released when the patient sneezes or coughs. Since droplets are heavy, they fall
rapidly usually within 3 feet of the patient. Whooping cough and meningococcal meningitis are examples of diseases spread this way. A private room is used and all persons entering must
wear a surgical mask.
![Page 28: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/28.jpg)
What are Airborne Precautions?
Airborne Precautions are used to prevent infections spread through the air. Unlike droplets, the germs involved with airborne diseases are so small that they can remain in the air for long periods of time and float on air currents. Tuberculosis, varicella (chickenpox) and measles are airborne diseases.
![Page 29: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/29.jpg)
What are Protective Precautions?
Protective Precautions are used for patients who are at high risk for acquiring infection.
A private room is used with special ventilation that prevents air from flowing from the hallway into the room (positive pressure room).
Staff and visitors must perform hand hygiene before entering the room and persons should not enter the room if they are Sick
Read the posted sign because at times special garments or gloves are required before entry.
![Page 30: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/30.jpg)
Let’s look at some other importantinfection control practices.
![Page 31: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/31.jpg)
Storage of Patient Supplies
Patient care items must be stored in a clean location at least 8 inches above the floor
Patient care items must not be stored in under-sink cabinets.
Since some items have expiration dates, it is important to establish a routine for checking dates.
![Page 32: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/32.jpg)
Proper Refrigeration
Monitor and maintain temperature between 2 and 8 degrees C Keep food/nourishments in a separate
refrigerator from medications/IV fluidsNEVER place lab specimens in a medication or
nourishment refrigerator
![Page 33: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/33.jpg)
Regular HospitalWaste
Regular hospital waste is placed in black trash bags.
Remember, before discarding items in the regular trash:
I. Empty fluid-filled containers such as IV bags and tube feedings
II. Remove any labels which have the patient’s name and/or medical record number
![Page 34: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/34.jpg)
Regulated Medical Waste Malaysian law requires that certain medical waste be
incinerated. Regulated medical waste must be placed in yellow trash bags. Examples of regulated medical waste include:I. Full sharps containersII. >20ml blood or blood products that cannot be easily
emptied (e.g., pleurevacs, blood administration tubing, evacuated containers)
III. Microbiology and Pathology specimensIV. Items used in the preparation and administration of
hazardous drugs
![Page 35: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/35.jpg)
Single-Use versus ReusablePatient Items
Many patient care devices and items are designed to be used with one patient and often only one time. These items are considered disposable and must not be resterilized or reused.
Read the manufacturer’s directions to be sure how a device is intended to be used.
![Page 36: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/36.jpg)
Cleaning and Disinfection
Reusable patient care devices/items must be properly cleaned and disinfected following STRICT guidelines.
Unless an item has been thoroughly cleaned, disinfection cannot occur.
Health care workers responsible for cleaning and disinfecting reusable patient items must be trained in these procedures.
![Page 37: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/37.jpg)
Renovation and Construction
Hospital construction generates dust and debris. Construction dust, including dust released from the
removal of ceiling tiles, may contain molds that can cause serious infections in high risk patients.
Plastic and solid wall barriers are designed to prevent movement of dust outside the construction site.
Contact your supervisor or an Infection Control Professional to report barriers that appear damaged.
Remember, only authorized personnel should enter a construction site.
![Page 38: Inf control for hcw 2012](https://reader034.vdocuments.us/reader034/viewer/2022042613/554b30ebb4c905a2058b4f5c/html5/thumbnails/38.jpg)
Linen handling and disposal Bedmaking and linen changing
techniques Gloves and apron - handling
contaminated linen Appropriate laundry bags Avoid contamination of clean linen Hazards of on-site ward-based
laundering
