Why take antibiotics?William Osler, MD (1849 - 1919)
"The desire to take medicine is perhaps the greatest feature which distinguishes man from animals."
"One of the first duties of the physician is to Educate the masses not to take medicine"
H. Cushing, Life of Sir William Osler (1925)

Antibiotics Changed the Human Survival
Antibiotics have transformed the practice of medicine, making once lethal infections readily treatable and making other medical advances, like cancer chemotherapy and organ transplants, possible.

Fleming Nobel Prize Speech identifies
In his Nobel Prize acceptance speech, Fleming identified the risk of bacteria becoming resistant to antibiotics. If a bacterium carries several resistance genes, it is called multiresistant or, informally, a "superbug."

What went wrong with Antibiotic Usage
Treating trivial infections / viral Infections with Antibiotics has become routine affair.Many use Antibiotics without knowing the Basic principles of Antibiotic therapy.Many Medical practioners are under pressure for short term solutions.

Poverty and Drug Resistance
Poverty encourages drug resistance due to under utilization of appropriate Antibiotics.
![Page 11: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/11.jpg)
ANTIMICROBIAL RESISTANCE:The role of animal feed
antibiotic additives48% of all antibiotics by weight is added to animal feeds to promote growth. Results in low, sub therapeutic levels which are thought to promote resistance.
Farm families who own chickens feed tetracycline have an increased incidence of tetracycline resistant fecal flora
![Page 12: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/12.jpg)
Inappropriate use of antibiotics
is a worldwide problemMore than 50% of all medicines are prescribed, dispensed or sold inappropriately, and half of all patients fail to take medicines correctly. The overuse, underuse or misuse of medicines harms people and wastes resources.
More than 50% of all countries do not implement basic policies to promote rational use of medicines.
![Page 13: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/13.jpg)
Creation of SUPERBUGSAntimicrobial resistance is a serious global challenge. Every continent and country faces the menace of antibiotic resistant “super bugs,” though the extent and the severity of the problem varies. There could be a return to the pre-antibiotic era, where many people could suffer or die from untreatable bacterial infections

Our Indian Hospitals Indian hospitals have reported very high Gram-negative resistance rates, with very high prevalence of ESBL (Extended Spectrum Beta Lactamases) producers and also high carbapenem resistance rates.
![Page 17: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/17.jpg)
Misuse of Antibiotics Drives Antibiotic Resistance
Studies prove that misuse of antibiotics may cause patients to become colonized or infected with antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE) and highly-resistant Gram-negative bacilli.
Misuse of antibiotics is also associated with an increased incidence of Clostridium difficle infections.
![Page 18: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/18.jpg)
Pan Drug Resistant InfectionsIncreasing carbapenem
resistance will invariably result in increased usage of colistin, currently the last line of defence, with a potential for colistin-resistant and Pan Drug Resistant bacterial infections
![Page 19: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/19.jpg)
Can we tackle the Problem India, with more than
20,000 hospitals, more than a billion population, wide cultural diversity, socio-economic disparity, and a large medical community of more than three-fourths of a million doctors, will find the resistance problem an issue very difficult to tackle
![Page 20: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/20.jpg)
Why is an antibiotic policy necessary?
An antibiotic policy will: Improve patient care by promoting the best practice in antibiotic prophylaxis and therapy, Make better use of resources by using cheaper drugs where possible Retard the emergence and spread of multiple antibiotic-resistant bacteria. Improve education of junior doctors by providing guidelines for appropriate therapy Eliminate the use of unnecessary or ineffective antibiotics and restrict the use of expensive or unnecessarily powerful ones
![Page 21: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/21.jpg)
An antibiotic policy will:

Aim of Antibiotic Policy
Reduce the Antimicrobial resistanceInitiate best efforts in the hospital area as many resistance Bacteria are generated in Hospital areas and in particular critical care areas.Initiate good hygienic practices so these bacteria do not spread to othersPractice best efforts, these resistance strains do not spill into critically ill patients in the Hospital
![Page 23: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/23.jpg)
Objectives of Antibiotic Policy.
Antibiotics should not be used casuallyPolicy emphasizes, avoiding the use of powerful Antibiotics in the Initial treatments.We should create awareness that we are sparing the powerful Broad spectrum Drugs for later treatment
Patient saves Money
Doctors save Lives.
![Page 24: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/24.jpg)
Aims of the Antibiotic Policy
Create awareness on Antibiotics as misuse is counterproductive.
More effective treatments in serious Infections.
Reduce Health care associated infections spilling to society and increase of Community associated Infections.
( A growing concern in Developing world )
![Page 25: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/25.jpg)
Policy Deals on Broad Basis
Clinicians / Microbiologists / Pharmacists and Nurses do take part.Policies are framed on demands of the Clinical areas, depending on recent Infection surveillance data contributed from Microbiology Departments.
![Page 26: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/26.jpg)
The 3 Stratagecies Will it Work ?Complete ban on OTC sale of antibiotics
without prescription throughout the country?.
Complete ban of OTC sale of antibiotics without prescription in metros and larger cities with a more liberal approach in smaller cities and villages.
A liberal approach throughout the country to start with, with an initial list of antibiotics under restriction and addition of other drugs to the list in a phased manner.
![Page 27: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/27.jpg)
Education On Antibiotic policy
Acton plan for Education to all concerned clinical staff on Antibiotic prescriptions. Evaluate the feed back of success and failures of the policy.Create Infection surveillance DataDeveloping facilities in Microbiology departments for auditing data and guidanceRestrictions in prescribing and Antibiotic availability.A continuous education to Junior Doctors
![Page 28: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/28.jpg)
Role of Microbiology Departments Microbiology labs
should issue hospital Antibiogram at pre-defined intervals. Those hospitals without good laboratory support should be willing to outsource samples to better laboratories.
![Page 29: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/29.jpg)
Role of Microbiology Departments
The system of notification of communicable diseases is a popular, established, though not strictly followed system in the country. Multidrug-resistant bacteria, especially pan-drug resistant bacteria, must be considered as a notifiable entity. Such a reporting system should complement national antimicrobial resistance surveillance studies.
![Page 30: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/30.jpg)
Better services from Microbiology Departments.
Basic infrastructure should be updated for detection of MRSA and ESBL and Carbapenamase producers.Documentation of all Opportunistic infections. and Hospital infection outbreaks
![Page 31: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/31.jpg)

WHONET DocumentationWhy We Need It
![Page 35: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/35.jpg)
What is WHONETWHONET is a free software developed by the WHO Collaborating Centre for Surveillance of Antimicrobial Resistance for laboratory-based surveillance of infectious diseases and antimicrobial resistance.
The principal goals of the software are:
1 to enhance local use of laboratory data; and
2 to promote national and international collaboration through the exchange of data.
![Page 36: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/36.jpg)
The understanding of the local epidemiology of microbial populations; the selection of antimicrobial agents; the identification of hospital and community outbreaks; and the recognition of quality assurance problems in laboratory testing.

All the Documented results are analyzed in WHONETThe heart of
WHONET is a software package designed to collect the results of antibiotic resistance tests. Researchers / Microbiologists feed the results into a computer and look for trends
![Page 38: Diagnostic Microbiology in Antibiotic Policy.pptx](https://reader035.vdocuments.us/reader035/viewer/2022062306/577cceac1a28ab9e788e27d2/html5/thumbnails/38.jpg)
Legacy computer systems, quality improvement teams, and strategies for optimizing antibiotic use have the potential to stabilize resistance and reduce costs by encouraging heterogeneous prescribing patterns and use of local susceptibility patterns to inform empiric treatment.
Implementation of WHONET CAN HELP TO MONITOR

Best way to keep the matters in Order
Every Hospital should have a policy which is practicable to their circumstances. The *Seniors physician in the respective
departments will make the best policy Rigid guidelines without coordination
will lead to greater failures The only way to keep Antimicrobial
agents useful is to use them appropriately and Judiciously
