CRITICAL CARE UNIT

2. INTRODUCTION
 The intensive care unit (ICU) of the hospital has always been where
the most vulnerable patients are kept, so they can be closely
monitored and treated, often with a one-to-one ratio of nurse to
patient, for the most scrupulous of care.
 Nosocomial infection comes from Greek work “nosus” meaning
disease and “ komeion ” meaning “to take care” also called as
“hospital acquired infection”.

3. DEFINITION
 An infection that occurs in a patient as a
result of care at any type of health care
facility and was not present at the time of
arrival to the hospital.
Infections are considered nosocomial if
they first appear 48hrs or more after hospital
admission or within 30 days after discharge.

4. • Nosocomial infections accounts for 7% in developed and 10% in developing
countries.Hospital waste serves as potential source of pathogens and about
20%–25% of hospital waste is termed as hazardous.
•The nosocomial infection was seen more in the 40-60 year of age. The male
were more prone to nosocomial infections than the female.
•Infection rate is upto 5% to 10% but may be up to 28% in ICU
•UTI - 28%,Surgical site infection – 19%,Pneumonia – 17%,Blood steam
infection – 7% to 10%
INCIDENCE

5. ENDOGENOUS
•Patient own flora may invade
patient tissue during some
surgical operation or instrument
manipulation
•Normal commensalism of the
skin respiratory , urinary track
EXOGENOUS
•From another patient , staff
members environment in the
hospital
•Environmental sources are air,
water, food
•Cross infection
SOURCES OF INFECTION

6. • Gram negative (pseudomonas aeruginosa, salmonella,
entero bacteriaceae) Gram positive bacteria
(staphylococcus, streptococcus,Micrococus
BACTERIA
• Hepatitis B, HIV, Cytomegalo virus, herpes
virus,Respiratory syncytial virus
VIRUS
• Candida albicans, Aspergillus,Saprophytic
fungi
FUNGI
• plasmodia, pneumocystitis carini
PROTOZOA
CAUSATIVE ORGANISMS OF
INFECTION

7. Lack of hand washing
Patient close together or
sharing room understaffing
Preparation of iv on the unit
Lack of isolation facilities in
separation of clean
Inadequate cleaning of
environment
RISK FACTORS

8. Ventilator-associated pneumonia
Staphylococcus aureus
Methicillin resistant Staphylococcus aureus
Candida albicans
Pseudomonas aeruginosa
Acinetobacter baumannii
Stenotrophomonas maltophilia
Clostridium difficile
COMMON NOSOCHOMIAL
INFECTIONS
Tuberculosis
Urinary tract infection
Hospital-acquired pneumonia
Gastroenteritis
Vancomycin-resistant
Enterococcus
Legionnaires’ disease.

9. Catheter-
associated
urinary tract
infection
(CAUTI)
Central line-
associated
bloodstream
infection
(CLABSI)
Surgical site
infection
(SSI)
Ventilator-
associated
events (VAE)
MAJOR HAI’S

10. Contact
Airborne
Oral route
Parenteral
route
 Contact : Hand or clothing
(staphylococcus aureus, streptococcus )
 Instrument : endoscope, bronchoscope,
(pseudomonas aeruginosa)
 Airborne : droplets of respiratory
infection transmitted by inhalation, dust
beding, floors, wound exudates & skin
(pseudomonas aeruginosa,
staphylococcus aureus)
 Aerosols : nebulizers humidifers & AC (
pneumophilia)
MODE OF TRANSMISSION

11. Contact
Airborne
Oral route
Parenteral
route
 Oral route :
Hospital food may contain antibiotic resistant
bacteria may colonize intestine can cause
infection
 Parenteral route:
Disposal syringes & needles , blood
transfusion ( hepatitis B, HIV)
MODE OF TRANSMISSION

12. •Avoid surgical site infection
•An isolation unit for a patient infected by an
infectious disease
•Sterilization of medical equipment
•Validation and cleaning of hospitals
environment
PREVENTION

13. PPE used in healthcare
includes
◦ gloves, aprons, long
sleeved gowns,
goggles, fluid-
repellant surgical
masks, face visors
and respirator
masks.
PPE

14. •Prevention and implementation of infection control policies
•Supervision of state of professional care with regard to infections
•Surveillance of nosocomial infection
•Analyze, interpret and disseminate data arising out of surveillance and to
recommend remedial measures and ensure follow up action
•Develop an antibiotic policy,
•To discuss infection control related audit findings and identify solutions to
issues
INFECTION CONTROL PROGRAMME

15. •Formulate policies & protocols on the methods of sterilization and
disinfection
•Employee health program
•Conduct in house orientation program
•Guidelines for segregation and disposal of hospital waste
•Conduct meeting every month (2nd Wednesday of every month)
INFECTION CONTROL PROGRAMME

16. Follow hand washing protocol
Follow biomedical waste management
Attend HICC related class
Follow aseptic techniques while doing
procedures
Follow care bundle protocols to prevent
nosocomial infections

27. SURVEILLANCE FOR NOSOCOMIAL
INFECTION
Definition :The collection tabulation interpretation and dissemination
of data on the occurrence of nosocomial infection or other untoward
event for the purpose of their prevention and control
Purposes:
 Establish baseline rate
 Evaluate polices and procedures
 Evaluate control measures
 Our break control
 Licensing

28. HOSPITAL INFECTION CONTROL
COMMITTEE
•Every hospital must have an effective Hospital-acquired Infection Control
Committee.Responsible for the control of HAIs
•The membership of the hospital ICC should reflect the spectrum of clinical
services and administrative arrangements of the health care facility.

29. 1.Chief executive, or hospital administrator or Medical superintendent (Chairperson).
2. Clinical microbiologist (Infection control officer).
3. Infection Control Nurse (ICN).
4. Infectious Diseases Physician (if available)
5. Chief of nursing services.
6. Medical record officer (if available).
7. Representative from the major clinical specialties.
8. Additionally representatives of any other department (pharmacy,maintenance,
housekeeping, etc) may be invited as necessary
HOSPITAL INFECTION CONTROL
COMMITTEE

30. To formulate & update policies on matters related to
 hospital infections
Review and approve surveillance and infection prevention program, emergence of
drug resistance
Use of different antimicrobial agents
Proper sterilization & disinfection procedures
To assess and promote improved practice at all levels of health facility.
To obtain and manage critical bacteriological data and information, including
surveillance data
