2. HEALTHCARE ASSOCIATED
INFECTION (HAI)
2
Also known as Nosocomial infection /
/Hospital acquired infection
/ Hospital associated infection
Also occupational infections among staff
For patients : Infections that first
appear 48hrs or more after hospital
admission or within 30 days after
discharge.
3. Some Statistics for HAI:
Affects ~ 10% of all in-patients
Delays discharge
Costs 2 x more than if there is
no infection
Show increasing
trend among patients
and staff
3
4. 4
Crowded hospital conditions
New microorganism
Increasing people with
compromised immune system
Increasing Bacterial resistance
(MRSA,resistant Gram negatives)
HAI reducible by 10-
30%
RISE IN HAI AS A RESULT OF 4 FACTORS
5. HAI - EPIDEMIOLOGY
5
Can be exogenous (external organism) and
endogenous (opportunist normal flora)
Host susceptibility : important factor in
development of HAI
MEDICAL EQUIPMENTS AND
PROCEDURES (surgery) are often responsible
for infections
6. HAI :Mode of Transmission
Contact/hand borne (most common)
Air borne
Oral route
Parenteral route
Vector borne
6
7. 1. Contact (most common)
Direct (physical contact)
◦ eg when a staff turns a
patient, gives patient a
bath , examination of
patient
7
8. 8
Indirect-contact Transmission
Involves contact of a host with a contaminated
intermediate object , eg:
Contaminated instruments / needles/dressings
Contaminated gloves that are not changed
between patient.
Contaminated surface by needles (Jarum diletak

Dried blood can transmit HEPATITIS B/C
9. 9
RISIKO HAI
Hep B virus can live outside d body
at least 7 days
Hep C virus can live outside d body
for 16h - 4 days
13. Hospital Procedure Pose Many
Risks to HAI
Nebuliser mask
Catheterization
IV Procedure
Dressing
Bedpans
Urinals
Dirty couch etc.
13
14. Predisposing Factors fOR
HAI
Age ( Young children ,
Elderly )
Severity of Illness
Medical conditions
Immuno compromised
Malnutrition
Obesity
14
15. COMMON SITES OF HAI
Patients in Labour Room / ICU
Patients undergoing invasive
procedures /operation.
Areas of hospital with poor ventilation
15
20. SURGICAL SITE INFECTIONS
20
Frequent
Definition is mainly clinical
(purulent discharge around wounds
or at insertion site of drain, or
spreading cellulites from wounds)
The infections can be exogenously
or endogenously
21. NOSOCOMIAL PNEUMONIA
21
Most important are patients
on ventilators in ICU.
Recent and progressive
radiological opacities of
pulmonary parenchyma,
purulent sputum and recent onset
fever.
22. PREVENTION & CONTROL OF HAI
1. Observance of aseptic technique
2. FREQUENT HAND WASHING
esp. between patients
3. Cleaning, and disinfection of
linen and furniture etc)
22
23. 23
PPE:Wear Gloves
For two reasons:
Provide a protective barrier
and prevent contamination of
hands
Reduce likelihood that
microorganism present on
hands will be transmitted
to patients during procedure.
25. HAND HYGIENETO PREVENT HAI
25
You can get 100s to 1000s of bacteria on your
hands by doing simple tasks like:Assisting pt
up in bed /Touching pt’s gown or bed sheets
HandWashing is Important Because…
80% of disease is spread by your hands.
Hand Hygiene : single most effective
intervention to reduce the cross
transmission of HAI
26. PREVENTION & CONTROL OF HAI
4. Sterilization of instrument eg
nebulizer/oxygen mask/Use of
single-use disposable items
5. Patient isolation eg Pertussis/TB
etc
6. Avoidance of medical
procedures that can lead to HAI
( eg. urinary catheter)
26
27. HAI :What is most Important
Effective surveillance and
action by infection control
team to reduce infection
rates.
Important role of team :
monitor compliance and
practices to prevent HAI
29. HCW - TB Cases & Notification Rate, Malaysia 2003-
2014
Control & Prevention Measures of TB among HCWs
Risk for TB among HCWs is consistently higher than
general population worldwide (Joshi, 2006)
29
31. iii. PPE
• N95 (respirator) must be used in high risk TB
areas
TB ward, chest clinic
Isolation room
Procedure room
eg. sputum induction room
• HCW to use N95
• Patient to use Surgical Mask
Control & Prevention Measures of TB among HCWs
31
32. Control & Prevention Measures of TB among HCWs
Conclusion
In addition to having TB guidelines with
environmental / engineering;
administrative; and respiratory-
protection controls;
HCWs must change their behaviour
towards healthy and safer work culture
in order to prevent & control TB at the
workplace.
