4. Capital of Gram negative resistance
Poor to absent infection control but
burgeoning private healthcare industry with
technological advances such as transplants
Newer drugs available abroad take time to
come
What is available is often not affordable
Irrational combinations abound due to poor
regulatory control
Antibiotic pipeline empty
5. Parameters Western world India
Common Isolates prevalent in ICUs Gram+ves Gram-ves
ESBL prevalence in gram –ves Much less Very high
Prevalence of ESBLs in last few years Slow increase Rapidly increasing
ICU type Mostly closed ICUs Mostly open ICUs
Generics Very few Hundreds of
generic
Restriction of antibiotic prescription Strict Relaxed
Guidelines made by western world keeping their issues in mind
may not suitable for India. 1

8. Kumarasamy KK, Toleman MA, Walsh TR, et al. Emergence of
a new antibiotic resistance mechanism in India, Pakistan, and
the UK: a molecular, biological, and epidemiological study:
◦ 44 isolates with NDM-1 in Chennai, 26 in Haryana, 37 in
the UK, and 73 in other sites in India and Pakistan.
◦ NDM-1 was mostly found among Escherichia coli (36) and
Klebsiella pneumoniae (111)
◦ Highly resistant to all antibiotics except tigecycline &
colistin
◦ Several of the UK source patients had undergone elective,
including cosmetic, surgery while visiting India or Pakistan
◦ “We would strongly advise against such
proposals…for UK patients to opt for corrective
surgery in India”

10. While other countries tackle
the problem
◦ US FDA banned off label
use of cephalosporins in
cattle, swine, chickens,
and turkeys effective 5
April 2012.
◦ Since April 2011, in Brazil
the use of antimicrobials
is no longer allowed
without a prescription
◦ Israel implemented a
nationwide plan to
monitor and control
carbapenemase resistant
Enterobacteriaceae with
an 80% reduction in rates
(Clin Infect Dis
2011;52:848)
11. Our health
ministry
came out
with an
excellent
document to
prevent
antimicrobial
resistance in
April 2011
Shelved it in
October
2011!
13. OTC use banned for drugs in this category
Warning boxes that advice against taking
except in accordance with medical advice
91 drugs added including most antibiotics
and anti-TB drugs
May be pruned down to 20-25 drugs
Will it be rationally decided?
Will it be implemented?

◦ What’s that
Where’s the hospital antibiogram, I asked?
◦ Anti-what?

40. Most Indian hospitals not
constructed with plumbing
at each bedside
Greater the distance to
basin, lazier we all get to
hand wash!
Microbiologically superior
to hand washing unless
hands visibly soiled
Less skin damage than soap
Have to have one per

45. Infectivity Prevention Perceived
after stick threat
Hepatitis B 30% Vaccine Low
Hepatitis C 3% None None
HIV 0.3% Post exposure High
prophylaxis
46. Recombinant DNA vaccine given in 3 doses at
0, 1 & 6 mths
Gluteal administration contra-indicated
Successful vaccination indicated by antibody
to HbsAg>10 mIU/ml
47. Consists of zidovudine 300 mg bd &
lamivudine 150 mg bd for 4 weeks
Second drug necessary only to cover the
possibility of zidovudine resistance
Of 18 documented failures of zidovudine, 8
involved source patients on zidovudine
Usually not warranted for mucosal and
intact skin exposures
Start ASAP, definitely within 24 hrs
49. For patients with multi-resistant bacteria
Consists of standard precautions plus unsterile
gloves whenever patient is touched, then
handwashing or hand rub immediately
Plastic gowns if extensive patient contact
Dedicated equipment eg stethoscope, BP
apparatus and thermometer
Sign at head of bed
Single room or cohort nursing for MRSA
One on one nursing essential

51. SARS in 2003 was when
we introduced N-95
mask concept
H1N1 in 2009 was a
challenge
◦ Treated a large no of
patients without a
hospital outbreak
◦ Vaccination of employees
introduced
52. Outbreak of XDR-TB in South Africa was mainly
nosocomial
Healthcare workers get active TB at rate of 5.8%
annually in developing countries, well above
general population
Smear negative TB is also transmissible though 4
times less likely, accounts for 13% of all cases (Clin
Infect Dis 2008;47:1135)
MDR-TB 5-6 times more infectious than historical
controls (PLoS Med 2008;5:e188)
Three types of strategies:
◦ Administrative controls eg Mantoux for HCW
◦ Environmental controls
◦ Personal protection eg N-95 masks
53. Mechanical ventilation delivering negative pressure
and 12 air changes per hour
◦ Costly, needs maintenance, may function poorly
◦ Needed for inpatient rooms, bronchoscopy
Natural ventilation
◦ High ceilings, large windows, open doors & windows
◦ Can provide up to 40 air changes per hour
◦ Applicable to OP settings and HIV settings
◦ Fails in extreme climates when windows closed
Upper room ultra-violet light
◦ Reduces airborne transmission by 70%
◦ Applicable to waiting room areas
54.
55. Common, seen in 10-20% of patients ventilated for >48 hrs
Intubation for
mechanical
ventilation
increases the
risk for
pneumonia
3x to 21x !
AJRCCM 2002; 165:867-903
56. Ventilator Associated Pneumonia
Semi recumbent posture
Avoid routine stress ulcer prophylaxis;
sucralfate is better (when needed)
Subglottic suctioning
Avoid tubing change q 24 hours
Selective decontamination of the digestive
tract
Avoid nasal intubation
Ref: N Engl J Med 1999;340:627-34
57. Catheter Related Bloodstream Infection:
(CRBSI)
Clinical catheter site infection (or)
Systemic signs of sepsis (c no other source)
AND
Positive catheter culture
(quantitative / semi quantitative)
AND
Same organism cultured in peripheral blood
58. Hand hygiene
Full Sterile barrier @ placement
Chlorhexidine is better than
povidone iodine site prep
Prefer subclavian site, avoid femoral
Antibiotic-impregnated catheters
Remove catheter when not required

60. Contamination rates in one study from 1974:
◦ bottle: 13%
◦ burette: 7%
◦ bag: 0.7%
Switched to viaflex collapsible bags
Avoided micro-infusion sets and vents
Used infusion pumps instead
Am J Hosp Pharmacy 1974;31:961
61. Use viaflex
collapsible bags
which do not need
vents in preference
to vented plastic or
glass bottles
Drops infection rate
from 6.52 to 2.36
per 1000 line days
West switched 30
years ago
Am J Infect Control 2004;32:135
62. Clinical
Culture based
Outpatient follow-up
Feedback
Can reduce SSI rates by 35-50%
Stratify monitoring to high risk group
63. Admission immediately pre-op
Same day clipping instead of
shaving
Avoiding hypothermia
Giving 1st dose antibiotic
within 1 hr pre-incision
Stopping antibiotics within 24
hrs
64.
65. Prospective
audit,
intervention and
feedback is the
cornerstone
Antibiotic forms
introduced
Special focus on
surgical
prophylaxis
66.
67.
68. Better implementation of antimicrobial
stewardship
Better adherence to hand hygiene regulations
Checklist approach
Need tighter regulatory control by authorities
◦ Antibiotics
◦ Hospital infection control programs
◦ Accreditation
69. Motion-activated video cameras were
strategically located throughout a medical
intensive care unit
