1.1 Introduction
• Infectious diseases have accounted for a very large proportion of diseases
ranked top ten causes of death worldwide in 2016 by WHO.
• Approximately 60% of all human infectious diseases recognized so far, and
about 75% of emerging infectious diseases that have affected people over
the past three decades, have originated from animals (WHO).
• Unfortunately many of these diseases could be prevented or cured for as
little as a single dollar per head

Int..cot’d
• It was not until the latter half of the 18th century that micro-
organisms were found to be responsible for a variety of infectious
diseases
• The discovery of these infectious agents stimulated the search for
appropriate preventative and therapeutic regimens; however,
successful treatment came only with the discovery of antibiotics
half a century later.

1.2 Magnitude of AMR
16
Mag..cot’d
• Antimicrobial resistance is increasing globally because of greater access
to antibiotic drugs especially in developing countries and spread of
resistant strains among humans and animals.
• Each year in the U.S., at least 2.8 million people are infected with antibiotic
-resistant bacteria or fungi, and more than 35,000 people die as a result.

Mag..cot’d - commonest etiologies
• Resistance to multiple drugs was first detected among enteric
bacteria—namely, Escherichia coli, Shigella and Salmonella—in the late
1950s to early 1960s.
• Several resistant bacteria have been increasingly involved in infectious
diseases
-ESKAPE; WHO as priority antibiotic-resistant bacterias’
-S. aureus is the resistant bacterium most familiar in the clinical setting
20
Mag..cot’d
In Ethiopia, AMR baseline survey conducted in 2009, revealed that
Coagulase negative staphylococcus, Streptococcus pneumoniae,
Salmonella species, and Staphylococcus aureus showed a considerable
degree of resistance to commonly used first line antibacterial agents.

MG is 24 years old man presented with Chief Complaint of Headache,
photophobia, painful and stiff neck, nausea and vomiting (5 to 6
episodes).
After thorough investigation of his clinical presentation the emergency physician suspected meningitis and
gave him 1gm ceftriaxone IV stat, 500mg azithromycin PO stat and 1gm paracetamol. Then after the patient is
transferred to the adult medical ward. The assigned resident in the medical ward make lumbar puncture for
CSF analysis and the sample was sent to the nearby laboratory facility. But, the laboratory investigation does
not revealed the presence of bacteria in the CSF but other findings are consistent with pyogenic meningitis.
Answer the following questions based on the above case scenario
a. Comment on the microbiology lab test
b. Reflect on the antimicrobial therapy of this patient
c. How can such practice contribute to antimicrobial resistance?

Chapter description
83
Objectives
Chapter Objective:
• By the end of this chapter, participants will be able to discuss the relationship
between IPC and AMR
Enabling Objectives:
Discuss basic concepts of IPC
Describe the core components of IPC
Identify IPC measures relevant to AMR prevention and containment
Describe interventions to prevent HCAI
84
3.1. Introduction
• Infectious diseases remain a major public health threat globally and could affect anyone
with the highest burden in LMICs
• In healthcare settings, the risk for infection is usually high due to risk factors such as the
presence of a wide range of infectious agents from various sources
• IPC refers to scientifically sound practices aimed at preventing harm caused by infection to
patients, health workers and the community.
• It is a systematic effort or process of placing barriers between a susceptible host and infectious
agents.
Thus, IPC is a critical component at every level of the health service delivery.
85
Introduction …
86
Introduction …
• IPC has two-fold benefit in containing emergence of AMR
• Reduces the risk of transmission of infections, thus minimize the necessity for, and
use of antimicrobials. This prevents the emergence of AMR
• Contains the spread of resistant microbes once resistance has emerged
• IPC is the 3rd strategic objective of the global and national action plan on AMR
(Reduce the incidence of infections though sanitation, hygiene and infection
prevention measures)
87
3.2. Basic concepts of IPC
88
Elements of the infection chain
Direct transmission: an immediate Bacteria,
transfer offungus,
virus, the infectious
agent parasite
• Key components
• Hand hygiene
• Use of Personal Protective Equipment (PPE)
• Respiratory hygiene and cough etiquette
• Safe injection practice
• Cleaning and disinfection of patient care equipment, instruments, devices, and
environmental surfaces
• Healthcare waste management 90
Standard and Transmission-based
Precautions…
• Transmission-based precautions
• Second level precautions
• For patients who may be infected or colonized with certain infectious
agents for which additional precautions is required
• used when the route (s) of transmission is (are) not completely interrupted
using standard precautions alone
91
3.3 Core Components of IPC
92
Reading assignment
93
Core components of IPC
• IPC is one of the fundamental strategy to combat AMR
• WHO recommends eight equally important core components crucial for the
establishment and effective functioning of IPC programmes and practices
1. IPC programmes: necessary premise for any IPC action at healthcare facility.
Link IPC to pertinent national programmes such as TB control, HIV/AIDS,
MNCH etc. for improved outcomes and sustainability.
3. Education and training: use the right educational method to achieve behavior
change. Monitor adherence with guideline recommendations.
94
Core components of IPC
4. Healthcare-associated infection (HCAI) surveillance: identify specific infections as
a priority for surveillance
6. Monitoring and audit of IPC practices and feedback: a quality improvement process
to achieve behavioral change and increase adherence to recommendations
8. Built environment, materials and equipment for IPC at the health facility level:
availability of basic equipment at point-of-care
95
3.4 HealthCare-Associated
Infections
96
Healthcare-associated Infections…
• The burden is growing globally
• Pooled prevalence of HACI in mixed patient populations in high-income countries
is 7.6% while 15.5% in low and middle-income countries
• Most commonly reported HCAIs are surgical site infections, urinary tract
infections, bloodstream infections (BSI) and hospital acquired pneumonia
98
Healthcare-associated Infections…
• Risk factors includes
• age >65 years,
• admission as an emergency and to the ICU,
• hospital stay longer than 7 days,
• placement of a central venous catheter,
• Indwelling urinary catheter, or an endotracheal tube,
• undergoing surgery,
• neutropenia,
• a rapidly or ultimately fatal disease and impaired functional or
coma status
99
3.5 IPC measures relevant to AMR prevention…
100
IPC measures for AMR prevention …
1. Hand hygiene
• Single most important practice
• Hand washing with soap & water or alcohol-based hand rub
• The cleansing activity is due to friction & the detergent properties of the
soap
• Time is also an important factor in hand washing (30 sec vs 15 sec)
• The entire hand washing procedure, if completed properly should take
40–60 seconds
• Volunteer to demonstrate steps of proper hand washing

IPC measures for AMR prevention …
Alcohol-based hand rub
• More effective in killing transient and resident flora than hand washing
• Has long-lasting activity
• Quick and convenient to use and can easily be made available at the point of
care
• Contains a small amount of an emollient (e.g. glycerol, propylene glycol, or
sorbitol) that protects and softens skin
104
Group discussion
• When is hand washing recommend as compared to alcohol-
based hand rub (ABHR)?
105
Group discussion
• When is hand washing recommend as compared to
alcohol-based hand rub (ABHR)?
• Hands visibly soiled or contaminated with blood or body fluids
• After using toilet
• Before eating
• To remove the buildup of emollients (e.g. glycerol) after repeated use of
ABHR
106
When is hand hygiene so relevant?
107
Hand hygiene and level of HCAI/resistant infection reduction
• A hospital-wide study in Saudi Arabia* showed that with significant increase
in HH compliance from 38% in 2006 to 83% in 2011, a reduction in
• MRSA infection from 0.42 to 0.08
• Ventilator associated pneumonia from 6.1 to 0.8
• Central line associated BSI from 8.2 to 4.8
• Catheter-associated UTI from 7.1 to 3.5
• Another study demonstrated sustaining HH at 80% or higher was
associated with a 48% further reduction of MRSA acquisition in a unit that
had comprehensive MRSA prevention measures**

IPC measures for AMR
prevention…
2. Use of PPE: proper donning and doffing is crucial
3. Sharps and injections safety: globally 50% of injections are unsafe. In Ethiopia,
74% injections are unsafe. Best practices in injections safety includes eliminating
unnecessary injection, safe administration of injections and disposal of injection
wastes and sharps properly
4. Environmental measures: cleaning and disinfecting surfaces that are most likely
to be contaminated
109
Summary
• IPC is an important components of the global and national AMR prevention &
containment strategy
• IPC has twofold benefit in AMR prevention.
• Minimize the need and use of antimicrobials at individual and community level by
reducing the occurrence of infections.
• It breaks the cross transmission of infections due to resistant microorganisms at
healthcare facilities
• Consistent hand hygiene practice has great impact in reducing HCAI and AMR
• Behavior change interventions targeting healthcare workers are fundamental
• Implementation of combination of IPC measures will
• Result in better patient outcomes,
• Reduce cost of medical care,
• Minimize length of stay,
• Reduce antimicrobial use and subsequently the emergence of AMR. 110

118
General guiding principles- 1. Principles of Testing
• Diagnostic test should be used wisely to avoid unnecessary
antimicrobial therapy or therapy that is unnecessarily broad-
spectrum.
• Rapid diagnostic tests and decision rules that have acceptable
performance characteristics to differentiate bacterial vs. non-
bacterial infection should be used.
• Bacterial cultures with susceptibility testing should be collated,
handled and processed promptly and appropriately to identify
specific bacteria causing infection.
• Avoid diagnostic testing without an appropriate clinical indication
119
General guiding principles- 2. Principles of Treatment
• Initial antimicrobial therapy choices should balance:
• treatment efficacy,
• severity of illness
• the potential for adverse events including the development of antibiotic resistance.

• Distribution of and training on educational material (e.g. clinical practice
guidelines)
• Using local key opinion leaders (champions) to advocate for key
messages
Persuasive • Audit with feedback to prescribers on their prescribing practice
(feedback) • AMS as a component of ward rounds (real-time feedback with educational
component)
Restrictive • Formulary restrictions
• Restricted prescribing of identified antibiotics (expert approval prior to
prescription)

AWaRe Classification of Antibiotics
128
AWaRe Classification of Antibiotics
ACCESS
• 1st-choice ATBs: sensitive, narrow-spectrum, low toxicity, propensity to develop
resistance
• 2nd-choice ATBs: sensitive, broader spectrum, higher risk of toxicity, potential to develop
resistance
• ATB of choice for most common infectious syndromes
• Must be available at all times
• Affordable and quality assured
• Lower priority for stewardship activities
• 60% or more of all ATBs consumed by 2023
129
AWaRe Classification of Antibiotics
WATCH
• Includes most of the highest-priority, critically important antimicrobials for
human and animal health
• Recommended only for specific, limited indications
• Includes sensitive ATBs with higher toxicity concerns, higher potential to
develop resistance
• Should not be used for prophylaxis in animal and agricultural production
• Target of AMS activities
• Must undergo active monitoring by using
– Prescription audits
– Point prevalence surveys
130
AWaRe Classification of Antibiotics
Reserve
Used as a last resort, when all other ATBs have failed or cannot be used
due to contraindications
Must also be accessible when needed
Newer generation ATBs
Use must be strictly limited to very specific patients and clinical settings
Protected and prioritized as key targets of strict AMS activities, central
monitoring and reporting

Antibiogram production and How to use
191
Antibiogram
An antibiogram is an overall prof il e/summery of antimicrobial
susceptibility testing (AST) results of a specif ic microorganism to a
battery of antimicrobial drugs.
This prof ile is generated by the laboratory using aggregate data from
a hospital or healthcare system; data are summarized periodically
and presented showing percentages (%) of organisms tested that are
susceptible to a particular antimicrobial drug.
Only results for antimicrobial drugs that are routinely tested and
clinically useful should be presented to clinicians.
192
Recommendations for Antibiograms/General conventions
– CLSI M39
Analyze/present cumulative antibiogram report at least annually;
Include only final, verif ied test results;
Include only species with testing data for ≥ 30 isolates.
Include only diagnostic (not surveillance) isolates
Eliminate duplicates by including only the f ir st isolate of a
species/patient/analysis period, irrespective of body site or
antimicrobial profile
Include only antimicrobial agents routinely tested; do not report
supplemental agents selectively tested on resistant isolates only.
Report %S (Susceptible) and do not include %I (intermediate) in the
statistic.

Antibiogram Uses:
• Guide the clinician and pharmacist in selecting the best empirical
antimicrobial treatment in the event of pending microbiology culture
and susceptibility results.
• Tools for detecting and monitoring trends in antimicrobial resistance.
• Guide clinicians/ pharmacists ability to de-escalate therapy once
pathogen ID is known but before AST available.
• May increase patient exposure to targeted, appropriate therapy
• May reduce the time a patient spends on broad-spectrum antibiotics,
which decreases the chance for development of resistance
194
Scope of applications of
ABG:
Staff utilizing
• Clinical decisions (e.g. clinical microbiologists, Infectious
disease specialist other clinical infectious practitioners,
pharmacists,
• Epidemiologists and others
195
Data Required to perform
ABG
1. Patient:
- Required: ID,
- Desirable: Age, Sex, Location (Ward), Admission date;
2. Specimen information:
- Required: number, type & date of collection.
- Desirable: Body site e.g. right orleft
196
3. Organism information:
- Required: identif ication up to the genus or species level
- Desirable: Isolate number, change in name of isolate (if
happen), Infection control data e.g. colonization or
infection, community- acquired, or healthcare
associated CA or HAI
4. AST information:
- Required: final MIC or zone diameter (ZD) used,
method used, special tests for detection of B-
lactamase, mecA gene, PBP2a by agar screening , PCR
or latex testing respectively.
- Desirable: detailed MIC or ZD
197
Frequency of Performance
At least once yearly.
More frequent with high number of isolates, new antimicrobial
introduced, or presence of important medical changes.
• Facility:
ABG is performed based upon local institution- specif ic
susceptibility data.
198
Table Staphylococcus aureus susceptibility test results for a sample patient.
Data presentation
In a tabular form.
Separate tables for Gram-positive, and Gram- negative,
Arrange the organisms within the table alphabetically, by organism
group of by the prevalence.
Some labs may present data by body site e.g. urine gram-negative
or gram-positive.
Antibiogram for critical care units (more resistant) e.g. ICUs better
to be separated to compare %S with the total hospital.
Comments upon the table must be included to explain it.
201
Presenting Emerging Resistance Trends:
Presentation of resistant organisms over years can be presented in
tables or graphs e.g.:
MRSA (S. aureus – %R for oxacillin - inpatient and outpatient);
VRE (Enterococcus spp. – %R for vancomycin isolates from sterile body
sites);
E. coli – %S to trimethoprim-sulfamethoxazole (urine isolates) and
fluoroquinolones;
ESBLs (K. pneumoniae and E. coli – % of isolates that produce ESBLs);
P. aeruginosa – %S to fluoroquinolones and/or imipenem.
202
Different ABG presentation formats
By nursing unit or care sits: i.e. patient location e.g. ICU, Burn unit,
Ward, OPD, nursing home for the better selection of site specif ic
empirical therapy.
By organism’s resistance character: especial for MDROs e.g.
MRSA, VRE, MDR Acineto., ESBLs.
By specimen type or infection site: e.g. urine isolates, blood
isolates).
By clinical service or patient population: to guide initial empirical
antimicrobial therapy for specif ic patient types (e.g. surgical,
pediatric, cystic f ibrosis, transplant, burn).
203
Distribution Formats:
