“Person playing with penicillin is morally
responsible for the death of the man who finally
succumbs to infection with the penicillin-resistant
organism. I hope this evil can be averted.”
•SIR ALEXANDER FLEMING NEW YORK TIMES JUNE 26, 1945
ANTIMICROBIAL USE
•Antibiotics are one of the
miracles of modern Science
•Antibiotics saved millions of
lives
This has led to their misuse through use without a prescription and
overuse for self-limiting infections
Antibiotics continue to save lives every day
•Neonatal care
•Transplantation
•Chemotherapy for
malignancy
•Immunosuppression
•Safe surgery
•Safe obstetric care
•Intensive care

PLANNING AND IMPLIMENTATION
ANTIMICROBIAL STEWARDSHIP IN
NICU
Symptoms of neonatal sepsis range from subtle to
severe, but are non-specific and may overlap with
many non-infectious clinical conditions in neonates.
Given the high risk of morbidity and mortality with
neonatal sepsis, and the poor positive predictive
value of ancillary laboratory tests
Empirical antibiotic treatment is often initiated,
targeting the most likely micro-organisms, based on
the clinical situation
Suspected sepsis is the most usual working diagnosis
Adverse effects of antibiotics in neonates
•Antibiotic-resistant neonatal sepsis
•Increase in rates of E. coli infections in VLBWs
•Broad spectrum
antibiotics exposure has
been associated with the
emergence of multi-drug
resistant gram-negative
bacilli and development
of invasive candidiasis.
•Prolonged duration of
empiric antibiotic
therapy for early onset
sepsis in extremely low
birth weight infants has
been associated with
increased risk of death
and Necrotizing
enterocolitis (NEC)
Unique Challenges in
Antibiotic Prescribing in the NICU
Signs and symptoms of sepsis in infants are non-
specific
Adequate blood quantities may not be feasible
to obtain for culture
Treatment guidelines are often not established
for infants, particularly for preterm neonates
•ASP IDSA 2016 Updates
facility-specific
guidelines for selected
common and important
infectious syndromes.
•Syndrome guidelines
should include a
recommended duration
of therapy for each
specific infectious
syndrome.
Certain clinical paradigms where the routine
use of antibiotics and choice of antibiotics is
being re-examined
2. CHOICE OF ANTIBIOTICS FOR LATE ONSET SEPSIS
1. EMPIRICAL ANTIBIOTICS FOR SUSPECTED SEPSIS IN TERM AND LATE PRETERM
INFANTS BORN TO MOTHERS WITH CHORIO-AMNIONITIS
3. CONTINUED ANTIBIOTIC USE IN THE NICU FOR CULTURE-NEGATIVE SEPSIS

NEONATES WITH SUSPECTED OR PROVEN EOS

Recommendations –
20% treated solely on the basis of abnormal laboratory data
EOS Calculator
Physical examination
1.Blood culture use decreased from 14.5% to 4.9%
2.Empirical antibiotic use in the first 24 h decreased from 5.0% to 2.6%
3.Without increases in readmissions for EOS within 7 days of birth
Asymptomatic infant with EOS –
Close observation of asymptomatic infants greater than 34 weeks
gestation born to mothers with suspected (not confirmed) intra
amniotic infection rather than initiation of empiric antibiotic therapy
Group of infants that receives a large proportion of antibiotics -VLBW
Higher prevalence of early
and late onset sepsis in
preterm/
VLBW infants
Concerns
about the reliability of
blood cultures
Difficulty in differentiating

sepsis from non-infectious
symptoms

NICU CARE BUNDLE
Small set of evidence-based
actions for a defined population
and care setting implemented
together in NICUs has been
associated with a reduction in
CLABSI rates
This multifaceted approach has
reduced the incidence of health

Implementing Antimicrobial Stewardship
1.Primary:
1.Formulary restriction and preauthorization (BII)
2.Prospective audit with intervention and feedback.(AI)
2.Secondary:
1.Education.(AII)
2.Guidelines and clinical pathways (AI)
3.Streamlining or de-escalation of therapy.(AII)
Needed to be applied
first in Developing
country like INDIA
1. Education
•Educational efforts include passive activities, such as conference
presentations, student and house staff teaching sessions
•Provision of written guidelines or e-mail alerts
•Introduction of the order form led to significantly improved
compliance (from 17% to 78%)
2. Guidelines and clinical pathways
•Recommendation
• Multidisciplinary development of evidence-based practice guidelines
incorporating local microbiology and resistance patterns can improve
antimicrobial utilization (A-I).
•Guideline implementation can be facilitated through provider
education and feedback on antimicrobial use and patient outcomes
(A-III).
Making Antibiotic Protocol
•Step 1 -Compile Local Hospital
data Based on Site of infection
•Organism spectrum
•Geographic Variations
(NICU/PICU/WARDS)
•% Distribution of Bugs
Step 2: Risk Stratification for MDRs
Step 3: Local Microbiological data
Step 4: De-escalation
•Discontinue / Taper down antibiotics
if negative cultures and patient
improving
•Diminish the number of antibiotics.
•Shorten length of duration of
antibiotics.
•Narrow spectrum of antibiotics.
