1.1 Introduction

Activity 1.1 Brainstorming


 What is Antimicrobial Resistance (AMR)?

5
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

Distribution of the leading causes of death in Africa in
2016

8
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.

Natural History of Antimicrobials

 Salvarsan (Arsphenamine) an organoarsenic compound-1910


 Prontosil, a sulfonamide- 1935
 In 1928, Fleming discovered penicillin
 In 1940 penicillin was introduced on a large scale as treatment of bacterial
infections and this was taken as the “Golden Era” of antibiotic.

12
Nat Hx…cot’d

• Antibiotics have revolutionized medicine in many respects, and countless


lives have been saved; their discovery was a turning point in human history.
• Antimicrobials are probably one of the most successful forms of
chemotherapy in the history of medicine.
• Unfortunately, we now live in an era where people around the world are
dying from untreatable infections because of the emergence and spread of
Antimicrobials resistance.

1.2 Magnitude of AMR

Activity 1.2 Individual reflection


 How deep is the problem of AMR?
 What do you think are the commonest etiologies
involved in AMR in your setup?

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.

17
Table 1: Cross-sectional Retrospective study on Antibiotic
resistant pattern at HUCSH July 2019

18
Figure 4: S.aureus Resistant over years in Ethiopia
19
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.

1.3. Causes and Mechanisms of AMR

Activity 1.3 Group Discussion


What are the factors associated with the
development and spread of antimicrobial resistance?

23
Causes
• heavy use of antimicrobials in hospitals and food
producing animals and agriculture
• inadequate dosing, substandard antimicrobials and
poor adherence
• not prescribing according to microbiology
results/absence of diagnostic facilities
• weak monitoring and regulatory systems
• poor infection control systems in health facilities:
improper disposal of antimicrobials…
• lack of surveillance and the dearth antimicrobial
stewardship programs
24
Mechanisms of AMR

Activity 1.3 Individual Reflection


• What are the types of microbial resistance?
• What are the possible mechanisms of antimicrobial
resistance?

25
Types of Microbial Resistance

• Some bacteria can be resistant naturally from plasmid proteins,


Intrinsic Resistance but most acquire resistance as a
consequence of evolution through a random error or
spontaneous mutation that occur during bacterial replication
upon exposure to antibiotics.
• Resistance genes can be transmitted among bacterias via
Vertical or Horizontal transmission

26
Development of microbial resistance

27
Examples of microbial resistance pathways

1) Decreased Uptake/modifying ab target: GM-ve, MRSA(PBP)/


2) Efflux Pumps: E-coli/TTC, quinelones…
3) Enzyme inactivation: b-lactamase(Salmonella..
4) Biofilms : periodontal disease, cystic fibrosis, chronic acne and
osteomyelitis

• AMR crisis will have a devastating cost on human society as
both debilitating and lethal consequences.

30
1.4.1. Consequences of AMR ….
 Increased morbidity & mortality.
 Longer duration of illness.
 Longer treatment
o Excess length of stay 6.4 – 12.7 days/patient
 Treatment with expensive drugs

o Complex surgeries
o Transplantations and other interventions

31
1.4.2. Impacts of AMR

Activity: Group activity on impacts of AMR


 In your small group discuss the impact of AMR in health and
economic aspects?

32
1.5.Global and National Response to
AMR

Activity 1.5 Individual reflection


 Mention the some of the global and national
responses to AMR

33
1.5.Global and National Response to
AMR

• To combat AMR appropriately and effectively, concerted


collaborative efforts are necessary across the human health,
animal health, and environment sectors. - One health approach

34
Global response to AMR
• The 68th World Health Assembly (WHA) passed a resolution in
May 2015 on the global action plan to contain AMR with Five
Strategic Objectives that member states can adapt and use.
• FAO’s Thirty-ninth Conference (in June, 2015) adopted
Resolution 4/2015 on AMR which recognized that it poses an
increasingly serious threat to public health and sustainable food
production, and that an effective response should involve all
sectors of government and society.

35
Global response to AMR

36
National response to AMR

37
National response to AMR….

38
National response to AMR …
• Established/strengthened multisectoral coordination
• Conducted various awareness creation events
• Provided training for health care and mass media professionals
• Developed national AMR Prevention and containment training
materials for health professionals;
• Established National AMR Coordinating Team, a secretariat
office in the Ministry of health;

39
National response to AMR …
• Developed National Human AMR Surveillance and Research
Plan
• Implementing various health facility and community-based
infection prevention and containment initiatives
• Developed Guidance of Antimicrobial Stewardship (AMS) for
hospitals in Ethiopian
• Undertaken Antimicrobial Use Point Prevalence Survey
• Categorized Antibiotics in the revised National Essential
Medicine List following AWaRe principles and use this as basis
for up-dating National Standard Treatment Guideline
40
1.6. Summary

• Antimicrobials resistance is one of the greatest global public health


challenges of our time.
• In Ethiopia, there are indications of the misuse of antibiotics by health care
providers, unskilled practitioners, and drug consumers. These, coupled
with rapid spread of resistant bacteria and inadequate surveillance,
contributed to the problem.
• The consequences of AMR are serious and global. Annual overall global
death toll could soar to 10 million by 2050 resulting in a sustained global
economic impact similar to, and likely worse than, the 2008 financial crisis.
• AMR is a biological, behavioural, technical, economic, regulatory, and
educational problem and requires a comprehensive response strategy
developed on the basis of evidence.

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?
d. Based on the comment adjustment taken and the patient has improved after 2 days. It was decided to
discharge, suggest actions to be taken by prescribers and dispensers.

• This chapter familiarizes participants with basic concepts of IPC.

• In addition, it describes the core components of IPC and provides an


overview of IPC measures relevant to the prevention and containment of
AMR

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

• Antimicrobials are used either to prevent or treat these infections

• 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 …

How does IPC measures


relate with AMR?
3 minutes

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,

Standard and Transmission-based
Precautions
• Standard precautions
• First level precautions to all patients
• Assumptions: every client and patient is potentially infectious or susceptible to
infection
• Maintenance of a physical, mechanical, or chemical barrier between
microorganisms, the environment, and an individual

• 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

• Three categories of transmission-based precautions


• Contact precautions
• Droplet precautions
• Airborne precautions

91
3.3 Core Components of IPC

92
Reading assignment

• Cross reference your response to the above question by


reading the core components of IPC from the participant’s
manual for 5 minutes

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.

2. Evidence-based IPC guidelines: adapted to local context

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

5. Multimodal strategies: implementation of several elements/components of IPC (3-5)


in an integrated manner

6. Monitoring and audit of IPC practices and feedback: a quality improvement process
to achieve behavioral change and increase adherence to recommendations

7. Workload, staffing and bed occupancy at health facility level

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

Healthcare-associated Infections…
• Microbiological patterns of HCAI reported gram-negative bacteria
(e.g. E. coli) and S. aureus as the most frequent single pathogens

• A systematic review of HCAI in Africa, reported


• the prevalence of methicillin-resistant Staphylococcus spp. ranged between
3.9% and 80% among the Staphylococcus spp.
• whereas gram-negative bacteria producing Extended Spectrum Beta-
Lactamase (ESBL) ranged between 1.9% and 53%

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

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**

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

5. Healthcare waste management: apply to all the generation, segregation,


collection, transport, storage, and disposal. The preferred strategy to implement is
minimizing waste generation

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

Conceptual value framework for implementation 116


Overview of AMS- Important considerations when prescribing antimicrobial
therapy:
• Obtaining an accurate diagnosis of infection;

• Understanding the difference between empiric and definitive therapy;

• Identifying opportunities to switch to narrow-spectrum, cost-effective oral agents


for the shortest duration necessary;

• Understanding drug characteristics that are peculiar to antimicrobial agents (such


as pharmacodynamics and efficacy at the site of infection);

• Accounting for host characteristics that influence antimicrobial activity;

• Recognizing the adverse effects of antimicrobial agents on the host.

117
Overview of AMS- General guiding principles

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.

• When multiple therapeutic options are available, a hierarchy of antibiotic


treatment recommendations should be provided with “f ir st choice”
options:
• Adequate therapeutic efficacy
• The lowest risk of facilitating antimicrobial resistance
• The lowest risk of healthcare value.
120

General guiding principles- 2. Principles of Treatment

• Optimal dosing of antibiotics should be based on:


• efficacy studies,
• Pharmacokinetic
• pharmacodynamics principles.

• Duration of therapy should be made, emphasizing the shortest


effective duration.

121

123
Antimicrobial stewardship program Strategies

124
Overview of AMS- interventions
Persuasive • Educational meetings (e.g. basics on antibiotic use, case-based
(education) discussions etc.)
• 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)
125
Structural • Rapid laboratory testing made available
Core strategies of Antimicrobial Stewardship program

The three core AMS strategies

• Formulary restriction with preauthorization

• Prospective audit with intervention and feedback

• Establishing multi-disciplinary AMS Program in health facilities

126
Formulary restriction and preauthorization

Why some medicines requires restriction or preauthorization? Potential to


promote resistance
 Potential to documented overuse or misuse (e.g. use of broad spectrum
antimicrobial over narrow spectrum agents are more appropriate)
 Need to reserve for treatment of multidrug resistant organisms
 Broad spectrum
 High cost
 Risk of serious adverse effects

127
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

131
132
Core strategies of ASP –AWaRe Classification of Antibiotics

133
Core strategies of ASP –Implementing AWaRe Guidelines and EML at the Facility
Level
• Start with creating or strengthening functionality of your DTCs/AMS Committee.
• Study national list of essential ATBs developed using the AWaRe criteria.
• Identify classes of ATBs stipulated for your level of facility.
• Study national treatment guidelines.
• Review your facility’s list of essential ATBs.
• Group your facility’s ATBs according to the national AWaRe categorization.
• Organize training of all prescribers and provide them with tools for planning,
implementation, and monitoring of AMS activities.
• Develop or adapt pocket guides, electronic apps, and other tools for prescribing
ATBs by following AWaRe guidelines.
• Set up a system to monitor implementation of AWaRe categorization.

134
Core strategies of ASP –Implementing AWaRe Guidelines and EML at the Facility Level

Exercise: As per the assignment from the Hospital DTC, the


formulary sub-committee requests the ASP team to review the
hospital’s specific list and classify Antibiotics in AWaRe.

1. What criteria will you follow to classify antibiotics

2. Classify the list as per the criteria and submit to the ASP team
before communicating to the formulary sub-committee.

(Use draft list at Annex 4.1 for the exercise)

Patient Identification Process

• Ask the patient to state identifying information.


• Patient name
• Medical record number
• Date of birth
• Government-issued photograph identification

155
Keeping specimens free of contamination
There are three main ways specimens are contaminated:

• From you, the person collecting the specimen

• From the patient, usually from the skin around where the
specimen was collected

• From the collection container, usually because the container


was broken or not stored properly

156
Agents commonly used to clean and prepare skin for specimen
collection 
(example for blood culture collection)

157
Collecting specimens in the right container

• The shape of a container can prevent contamination and may


limit volume (amount).

• Some containers have chemicals that are needed for certain


tests but will ruin the specimen for others.

• Collect in the appropriate, clean, leak proof-sterile containers.

158
Timing: Collecting specimens at the right (optimal)
time
• Collect specimens before antibiotics are given. If not possible
indicate on the requisition form.

• Collect specimens during acute phases of illness (e.g., when a


patient is febrile) as etiologic agents are more likely to be
detected.

• Collect urine specimens early in the morning ideally as the f irst


urination.

• Minimize Transport Time or Maximize Transport Media. There is Always


Some Loss of Viability During Transport ( if so the quality of result will
compromise ) 159
Volume: Collecting the right amount

• A suf fic ient quantity of the specimen must be obtained to


perform all the requested tests.

• Volume may differ by patient age

• Small specimens are especially problematic

• For blood, the sensitivity of culture is directly related to the


amount of blood submitted

160
A sufficient quantity of the specimen must be obtained to
perform the requested tests

161
Safe Specimen Labeling

• For any specimen, there are necessary items that need to be


present on the label and they must all be correct or the
specimen will be rejected

• EVERY individual tube, container, specimen sent to the lab must


have a label applied to it (not loose in the bag).

162
Transporting specimens to the lab

• Minimize transport time

• If transport time increases, microorganisms can die and others can


overgrow

• Specimens should be transported to the lab within 2 or accordingly

• Transport media may need to be used if transport time >1 hour

• Delay in transport compromise the quality of sample and result


inaccurate result

163
Institution Policies

The institution needs to provide the following information before


the collection of the specimen:
• Laboratory operation hours
• Contact person information
• List test performed routinely (laboratory guide) including the
time to results or days of testing (batched test and STAT
(immediate) testing

164
Requisition Form

• A completed requisition should include:


• Patient’s name and identification number
(patient’s unique identifier)
• Patient’s address, location (hospital ward,
clinic, etc.)
• Patient’s age, gender, phone number
• Description and source of specimen
• Date and time of specimen collection
• Date and time of sample arrival at lab
• Name of collector and who to contact with results
165
Rejection Criteria

• These are the conditions upon which a sample that the clinician
collected will be rejected:
1. Unlabeled sample
2. Broken or leaking tube/container
3. Obviously contaminated specimen
4. Insufficient patient information
5. Sample label and patient name on the test request form do
not match

166
Sample Disposal

• Set policy for sample disposal, or refer to lab policy


• Compliance with local, country and international regulations

167
Summery

• Culture results are dependent on the quality of the specimen


submitted. This includes:
• Collection from the correct anatomic site
• Using the proper technique and the required supplies
• The most important step in sample management is proper
sample collection for culture

ANTIMICROBIAL SUSCEPTIBILITY TESTING

• AST Methods
• Reading and interpretation of AST plates
• CLSI Guidelines - Document M100

183
READING PLATES

• KB is a standardized procedure for performing AST by disk diffusion

• Results are recorded as sensitive, intermediate, or resistant based on


a standardized table of zone sizes

• Plates should be read after 16 to 18 hours* of incubation.

Zone measurements compared to CLSI


Guidelines to interpret susceptibilities

184
SELECTING ANTIMICROBIALS FOR SUSCEPTIBILITY TESTING

• Selection of the most appropriate antimicrobial agents to test and


report must be determined for each hospital

• The clinical laboratory must consult with Infectious disease


practitioners and the pharmacy to determine what antimicrobial
agents to use in the laboratory for testing and reporting

185
Cont’d….
• Group A are considered appropriate for inclusion in a routine,
primary testing panel, as well as for routine reporting of
results for the specific organism groups.
• Group B includes antimicrobial agents that may warrant
primary testing, but they may be reported only selectively,
such as when the organism is resistant to agents of the same
antimicrobial class, as in group A

186
Cont’d..

Group C - alternative or supplemental agents that may require


testing in institutions for one of the following reasons:
• Hospital harbors epidemic or endemic strains of organisms
resistant to several of the primary drugs (Group A)
• For treatment of patients allergic to primary drugs (penicillins)
• For treatment of unusual organisms

187
Cont’d …
Group U (“urine”) – inc ludes c er t ain ant imic rob ial ag ent s (eg ,
nitrofurantoin and certain quinolones) that are used only or primarily for
treating UTIs.
Group O (“other”) – includes agents that have a clinical indication for the
organism group, but are generally not candidates for routine testing
and reporting in the US
Group Inv. (“investigational”) - includes agents that are investigational
for the organism group and have not yet been approved for use in the
US

Antibiogram production and How to use 

Activity:5.1.3 Check-In Questions power points


presentation
 What is a cumulative antibiogram?

 Describe how to analyzing and presenting


Antimicrobial test data for clinical microbiologis
t ,pharmacists and physicians (How is a
Cumulative Antibiogram Useful?)

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.
193
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.

 Recommended species to be included (even if <30 isolates) in the


tables
200
Example of ABG data Report by alphabetically

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:
 In easy accessible formats to all prescribing Physicians,
Infection control staffs, Pharmacists, Epidemiologists &
Microbiology Staffs‘:-
 Small cards in coat pocket

 Or in laminated sheets.

 In the institution website (Intranet). As application or PDF.

 Printed formats especially in special areas like ICUs.

Overview of Ethiopian laboratory-based AMR
surveillance system

209
Introduction
• The Ethiopia AMR Surveillance Plan was developed and launched by
the Ethiopian Public Health Institute (EPHI) in 2017.

• It began and started at four laboratories (Phase I sites) and now

it is in its second year of implementation and expanded to phase II


sites(5 sites).

• The AMR surveillance is implemented in collaboration with partners:


Center for Disease Control and Prevention CDC), American Society for
Microbiology(ASM) & Ohio State University(OSU)

210
Methods
• Ethiopian public health laboratory –based surveillance system
Captures priority isolated data from routine clinical laboratory.

• Manual microbiology methods were used for antimicrobial


Susceptibility testing

211
Priority surveillance pathogens for AMR, &
Sample collection
Three priority pathogens – Escherichia coli, K. pneumoniae– isolated from
urine, and Staphylococcus aureus isolated from wound specimens, as well
as carbapenem-resistant Acinetobacter spp., Pseudomonas aeruginosa, and
Enterobacteriaceae from any clinical specimen.

212
Current AMR sentinel sites and activities

213
AMR surveillance report or findings
• Data management and analyses are done using WHONET
software.

214
Surveillance Limitations and Challenges
• The availability of quality microbiology testing
• Staff turnover, shortage, and lack of motivation at all levels.
• Poor infrastructure of microbiology laboratories in many health care
facilities across the country
• Weak communication b/n clinicians and laboratory technologists
• Weak ownership of the program by participating sites
• Data management related operational challenges
• Resource challenges to expand surveillance sites

228
Summery

• The rise of AMR is being accelerated by excessive antibiotic use in


humans, animals and the agricultural sector.
• Shortage of the right antibiotics and suboptimal antibiotics prescribed are
accelerating the resistance among bacterial population
• ASP and AWaRe classification cannot exceed without involvement of
medicine procurement to insure timely availability of antimicrobials
• Ensuring a strong supply chain of reliable diagnostic tests, reagents, and
consumables is one of the key factors for creating a sustainable, strong
diagnostic laboratory system.
• There are three broad strategies stakeholders need to use to improve the
effectiveness and efficiency of supply chains and improve access.
