Antimicrobial stewardship programs

In resource poor settings

Prof Gunturu Revathi

Dept of Pathology

The Aga Khan University Hospital

Nairobi

ICAN Harare Zimbabwe

A 35-year-old female no past medical history presents to the AampE complaining of cough and shortness of breath for 2 days that is progressively worsening

On physical examination

She is febrile with an oxygen saturation of 94 on room air

Decreased breath sounds at the right base

A chest x-ray shows right lower lobe consolidation

70-year-old female with fever nausea and back pain for 3 days

Her daughter states her mother had a similar presentation when she had a UTI 2 years ago

She is febrile to 383degC (101degF) with left costo-vertebral angle tenderness

Her urine dipstick is positive for leukocyte esterase and nitrites

An 85-year-old male brought in for evaluation for fever He has a history of insulin-dependent diabetes mellitus hypertension and dementia

On physical examination he is febrile with otherwise normal vital signs

His abdomen is slightly distended soft but diffusely tender to palpation

Is this diseasehellip

really the same as

this disease

The antimicrobial agents - unique drugs

Efficacy is higher than others in reduction of morbidity and mortality

Antibiotics are the only group of drugs with ecological effects

Contribute to the emergence and spread of microbial resistance

Finally they are used by almost all medical specialties

Appropriate use of antimicrobials is highly complex

because of the important advances in the management of infectious diseases and the wide spread of antibiotic resistance

Evidence-based medicine (EBM) is the new mantra

The best available evidence be used to aid clinical decision-making and policy

EBM has changed medical practice

It raises many questions

Randomized controlled trials (RCT) - the cornerstone of EBM

Extrapolating knowledge from RCTs to individual patients across different settings - a big problematic

Such extrapolations require much more evidence which is often unavailable

Evidence is needed for

Efficacy (ldquoCan it workrdquo)

Effectiveness (ldquoDoes it work in practicerdquo)

Efficiency (ldquoIs it worth itrdquo)

All of these need to be considered

Most trials test for efficacy in ideal situations using

Detailed protocols

Carefully selected patients

Poor diagnostic accuracy

Poor patient compliance

The antimicrobial agents - unique drugs

Efficacy is higher than others in reduction of morbidity and mortality

Antibiotics are the only group of drugs with ecological effects

Contribute to the emergence and spread of microbial resistance

Finally they are used by almost all medical specialties

Appropriate use of antimicrobials is highly complex

because of the important advances in the management of infectious diseases and the wide spread of antibiotic resistance

Stanford University School of Medicine in Stanford Calif

Evidence-based medicine (EBM) is the new mantra

The best available evidence be used to aid clinical decision-making and policy

EBM has changed medical practice

It raises many questions

Randomized controlled trials (RCT) - the cornerstone of EBM

Extrapolating knowledge from RCTs to individual patients across different settings - a big problematic

Such extrapolations require much more evidence which is often unavailable

Evidence is needed for

Efficacy (ldquoCan it workrdquo)

Effectiveness (ldquoDoes it work in practicerdquo)

Efficiency (ldquoIs it worth itrdquo)

All of these need to be considered

Most trials test for efficacy in ideal situations using

Detailed protocols

Carefully selected patients

Placebo controls

Good treatment compliance

And intensive follow-up

These ideals - rarely achievable in routine clinical practice with

Poor diagnostic accuracy

Poor patient compliance

And partial patient coverage

Tragic Paradox in

Developing countries

Kenya is no exception

The World Health Organization (WHO) estimates - lt 25 of children with pneumonias receive antibiotics resulting in significant mortality

Mortality in adults with bacterial infections - a major concern

Lack of access to affordable medical care for the vast majority of the rural population

The urban-centric nature of our health care delivery system contributes to preventable deaths

The current scenario in developing countries makes antibiotic stewardship quite challenging

Absence of lab services of any kind

Diagnosis of serious infective conditions including acute meningitis childhood TB is made based on clinical algorithms

Majority of the public health care facilities operate with out a clinical laboratory

A lot of empirical prescribing in private clinicsIn public sector by clinical officers with limited training and scanty updating of medical knowledgeLab facilities not available not accessible too expensive

Major areas of concern

Lack of emphasis on specific diagnosis Clinical misdiagnosis

Inadequate health care infrastructure

laboratory capability and diagnostic accuracy

Lack of emphasis on lab diagnosis of infectious diseases ndash clinician apathy and a culture of syndromic approach

Concept that microbiology is expensive and time consuming

Perceptions that Lab results can not be trusted - Justified indeed

I AM CONCERNED ABOUT THE HIGH LAVELS OF BLOOD WE FOUND IN YOUR BLOOD TEST

HEAVY MIXED GROWTH OF THREE TYPES OF COLONIES

Why is there an ldquoincreaserdquo in the diagnosis of Enteric Fever (Typhoid)

John P A Ioannidis

Stanford University School of Medicine in Stanford Calif

Evidence-based medicine (EBM) is the new mantra

The best available evidence be used to aid clinical decision-making and policy

EBM has changed medical practice

It raises many questions

Randomized controlled trials (RCT) - the cornerstone of EBM

Extrapolating knowledge from RCTs to individual patients across different settings - a big problematic

Such extrapolations require much more evidence which is often unavailable

Evidence is needed for

Efficacy (ldquoCan it workrdquo)

Effectiveness (ldquoDoes it work in practicerdquo)

Efficiency (ldquoIs it worth itrdquo)

All of these need to be considered

Most trials test for efficacy in ideal situations using

Detailed protocols

Carefully selected patients

Placebo controls

Good treatment compliance

And intensive follow-up

These ideals - rarely achievable in routine clinical practice with

Poor diagnostic accuracy

Poor patient compliance

And partial patient coverage

One report - as many as two-thirds of studies related to preclinical animal trials were not able to be reproduced

problem is not scientific fraud but a combination of factors -- including the pressure to publish rapidly and poor training in experimental design

John P A Ioannidis

Stanford University School of Medicine in Stanford Calif

Evidence-based medicine (EBM) is the new mantra

The best available evidence be used to aid clinical decision-making and policy

EBM has changed medical practice

It raises many questions

Randomized controlled trials (RCT) - the cornerstone of EBM

Extrapolating knowledge from RCTs to individual patients across different settings - a big problematic

Such extrapolations require much more evidence which is often unavailable

Evidence is needed for

Efficacy (ldquoCan it workrdquo)

Effectiveness (ldquoDoes it work in practicerdquo)

Efficiency (ldquoIs it worth itrdquo)

All of these need to be considered

Most trials test for efficacy in ideal situations using

Detailed protocols

Carefully selected patients

Placebo controls

Good treatment compliance

And intensive follow-up

These ideals - rarely achievable in routine clinical practice with

Poor diagnostic accuracy

Poor patient compliance

And partial patient coverage

33

Tragic Paradox in

Developing countries

Kenya is no exception

The World Health Organization (WHO) estimates - lt 25 of children with pneumonias receive antibiotics resulting in significant mortality

Mortality in adults with bacterial infections - a major concern

Lack of access to affordable medical care for the vast majority of the rural population

The urban-centric nature of our health care delivery system contributes to preventable deaths

The current scenario in developing countries makes antibiotic stewardship quite challenging

Absence of lab services of any kind

Diagnosis of serious infective conditions including acute meningitis childhood TB is made based on clinical algorithms

Majority of the public health care facilities operate with out a clinical laboratory

A lot of empirical prescribing in private clinicsIn public sector by clinical officers with limited training and scanty updating of medical knowledgeLab facilities not available not accessible too expensive

Major areas of concern

Lack of emphasis on specific diagnosis Clinical misdiagnosis

Inadequate health care infrastructure

laboratory capability and diagnostic accuracy

Lack of emphasis on lab diagnosis of infectious diseases ndash clinician apathy and a culture of syndromic approach

Concept that microbiology is expensive and time consuming

Perceptions that Lab results can not be trusted - Justified indeed

Evidence-based medicine (EBM) is the new mantra

The best available evidence be used to aid clinical decision-making and policy

EBM has changed medical practice

It raises many questions

Randomized controlled trials (RCT) - the cornerstone of EBM

Extrapolating knowledge from RCTs to individual patients across different settings - a big problematic

Such extrapolations require much more evidence which is often unavailable

Evidence is needed for

Efficacy (ldquoCan it workrdquo)

Effectiveness (ldquoDoes it work in practicerdquo)

Efficiency (ldquoIs it worth itrdquo)

All of these need to be considered

Most trials test for efficacy in ideal situations using

Detailed protocols

Carefully selected patients

Placebo controls

Good treatment compliance

And intensive follow-up

These ideals - rarely achievable in routine clinical practice with

Poor diagnostic accuracy

Poor patient compliance

And partial patient coverage

Evidence is needed for

Efficacy (ldquoCan it workrdquo)

Effectiveness (ldquoDoes it work in practicerdquo)

Efficiency (ldquoIs it worth itrdquo)

All of these need to be considered

Most trials test for efficacy in ideal situations using

Detailed protocols

Carefully selected patients

Placebo controls

Good treatment compliance

And intensive follow-up

These ideals - rarely achievable in routine clinical practice with

Poor diagnostic accuracy

Poor patient compliance

And partial patient coverage
