2. Case 1:
• 1 yr old male child
• Presented with fever, respiratory distress and
stidor
• Intubation was performed and
dexamethasone was administered
• After two days , child presented with signs and
symptoms of aspiration pneumonia
3. Case 2:
• A 5 months old male child
• presented with a.w.d , severe dehydration &
acute kidney dysfunction
• Rehydration
• For Kidney function monitoring urinary
catheter was inserted
• With in 36 hrs diarrhea was resolved, but
patient showed signs of infection
4. Case 3 :
• 5 years old female presented to hospital with fever ,
respiratory distress
• 1st diagnosed as T.B pt , latter ruled out, ceftriaxone
was prescribed and held latter diagnosed with
pneumonia
• Benzyl penicillin & co amoxicalve were prescribed
• No improvement was found after 3 days ciprofloxacin
was prescribed but in sub therapeutic dose,
• Latter effusion n consolidation was diagnosed
• and vancomycin ,tanzo and clarithromycin were
added to regimen
• after 20 days the microbe was found resistant to
quinolones, aminoglycocides, microlides , beta
lactam antibiotics. Only vancomycin was effective
5. Point to ponder !
• Similarity between these
cases:
• All were by inflicted by
infections after admission to
hospital
8. NOSOCOMIAL INFECTIONS
• Hospital acquired infections / nosocomial
infections.
• The term "nosocomial" comes from two Greek
words:
• "nosus" meaning "disease" + "komeion"
meaning "to take care of.“
• Hence, "nosocomial" should apply to any
disease contracted by a patient while under
medical care .
9. Definition
According to WHO
• An infection acquired in hospital by a patient who
was admitted for a reason other than that
infection .
• An infection occurring in a patient in a hospital or
other health care facility in whom the infection
was not present or incubating at the time of
admission. This includes infections acquired in the
hospital but appearing after discharge, and also
occupational infections among staff of the facility
.
11. Who is responsible for noscocomial
infections?
1
• Patient –for visiting hospital
• for weak immunity
2
• Doctor-for prescribing antibiotics
• For invasive procedures
3
• nurses-for not using aseptic
procedures
4
• Hospital cleaners-for not being
glued to mop & phenyl
5
• Microbes-for being there in 1st
place
Where is pharmacist in
this chain?
May be we are too busy
in avoiding the blame

24. ROLE OF NURSES & PHYSICIANS
– Use of aseptic techniques while administering
parental
– Use of gloves, and hand washing practice
– Use of no touch technique , as far as possible.
– Keeping check of i/v & catheter inflicted infections
– Ensure that housekeeping is performing its
functions properly
25. DEVELOPMENT OF
PERFORMANCE MANUALS
• Infection control committee must
develop manuals for , food providing
services , housekeeping services , laundry
services, hospital hygiene services
• Organize surveillance program for
nosocomial infections
• Involve pharmacy in development of
supervision program for use of anti
infective drugs
26. Education & training
• Organize teaching programs for medical ,
nursing , allied health personnel
• Arrange courses for awareness of pharmacist
so that they may supervise nursing staff for
proper dispensing of medicines
• Provide expert advice , analysis & leadership
in outbreak investigation & control
• Undertake research in hospital hygiene &
infections
27.
28. • Rates OF infection are obtained by
dividing a numerator (number of
infections or infected patients
observed) by a denominator
(population at risk, or number of
patient-days of risk). The frequency
of infection can be estimated by
prevalence and incidence indicators
29. PHASES of nosocomial infections
control
• Surveillance
• Policy
development
1st phase
2nd phase
• Implementation
• Control measures
• Hygiene protocols
• Control of modes
of transmission
3rd phase
30. Arrest of Modes of transmission
Contact transmission
• Droplet transmission
Airborne transmission
• Common vehicle transmission
Vector borne transmission
31. Methods to control modes of
transmission
• Reducing person-to-person
transmission
• Hand decontamination
• Safe injection administration
• Preventing transmission from the
environment
35. Guidelines for physicians, nurse &
pharmacist
• Wash hands promptly after contact with infective
material
• Use no touch technique wherever possible
• Wear gloves when in contact with blood, body
fluids, secretions, excretions, mucous membranes
and contaminated items
• Wash hands immediately after removing gloves
• All sharps should be handled with extreme care
36. Guidelines
• Clean up spills of infective material
promptly
• Ensure that patient-care
equipment, supplies and linen
contaminated with infective material is
either discarded, or disinfected or
sterilized between each patient use
• Ensure appropriate waste handling
• If no washing machine is available for
linen soiled with infective material, the
linen can be boiled.
37. Cleaning of the hospital environment
• Zone a-no pt –normal domestic cleaning
• Zone b-pt –non infected-not highly susceptibleno dry cleaning, use of detergent solutions
• Zone c-infected pts-disinfectant/detergent
solution, separate cleaning equipment for each
unit
• Zone d-highly susceptible pts-protected/
isolated-disinfectant/detergent solution,
separate cleaning equipment for each unit
38. Sterilization & disinfection
• Use of hot/superheated water
• Disinfection with hot water
• 1. Sanitary 80 °C 45–60 seconds
equipment
• 2. Cooking 80 °C
1 minute
utensils
• 3. Linen
70 °C

40. Water born infections
•
•
•
•
•
•
Acinetobacter calcoaceticus
Legionella pneumophila and other
Mycobacteria:
Mycobacterium xenopi
Mycobacterium chelonae
Mycobacterium avium-intracellularae
41. Microbiological monitoring
• Regulations for water analysis (at the national
level for drinking-water, in the Pharmacopoeia for
pharmaceutical waters) define criteria, levels of
impurities, and techniques for monitoring.
• Methods used for monitoring must suit the use.
• Infections attributable to water are usually due to
failure to meet water quality standards for the
specific use.
• Infection control/hygiene teams must have
written, valid policies for water quality to
minimize risk of adverse outcomes attributable to
water in health care
settings.
42. Airborne infections
•
•
•
•
•
•
•
Depend on :
1.Type of infections
2. Quality of air provided
3. Rate of air exchange
4. Number of persons present in wards
5. Movement of personnel
6. Level of compliance with infection control
practices
• 7. Quality of staff clothing
• 8. Quality of cleaning process
43. Control of airborne infections
• Appropriate ventilation is necessary, and must
be monitored within risk areas, e.g.
orthopedics, vascular surgery and
neurosurgery.
• Unidirectional airflow systems should be
incorporated in appropriate areas in new
hospital construction
44. Control of vectors
•
•
•
•
•
•
•
•
Arthropods :
Cockroaches are source of Streptococcus species
Bacillus species (except Bacillus subtilis)
Bacillus subtilis
Staphylococcus aureus
Staphylococcus epidermidis
Enterococcus species
Corynebacterium species
45. control of cockroaches
• The keys to controlling cockroaches are
sanitation and exclusion: cockroaches are
likely to reinvade as long as a habitat is
suitable to them (i.e., food, water, and shelter
are available)
• Sprays can be used to suppress the population
47. Precautionary measures to avoid
infections
• traffic flow to minimize exposure of high-risk
patients and facilitate patient transport
• adequate spatial separation of patients
• adequate number and type of isolation rooms
• appropriate access to hand washing facilities
• appropriate ventilation for isolation rooms
and special patient care areas (operating
theatres,transplant units)
• preventing patient exposure to fungal spores
with renovations

patient day (P.D.), a unit in a system of accounting used by health care facilities and health care planners. Each day represents a unit of time during which the services of the institution or facility are used by a patient; thus 50 patients in a hospital for 1 day would represent 50 patient days. Evaluation of the surveillance strategyReview whether the surveillance system meets therequired characteristics (19,20): simplicity/flexibility/acceptance timeliness (is the feedback prompt enough to beuseful?) utility (in terms of priorities, impact, etc.) efficacy/efficiency
Methods must be appropriate for the likelihoodof contamination, and necessary level of asepsis.This may be achieved by classifying areas intoone of four hospital zones (8):— Zone A: no patient contact. Normal domesticcleaning (e.g. administration, library).Zone B: care of patients who are not infected,and not highly susceptible, cleaned by a procedurethat does not raise dust. Dry sweepingor vacuum cleaners are not recommended. Theuse of a detergent solution improves the qualityof cleaning. Disinfect any areas withvisible contamination with blood or bodyfluids prior to cleaning.— Zone C: infected patients (isolation wards).Clean with a detergent/disinfectant solution,with separate cleaning equipment for eachroom.— Zone D: highly-susceptible patients (protectiveisolation) or protected areas such as operatingsuites, delivery rooms, intensive care units,premature baby units, casualty departmentsand haemodialysis units.
