Antimicrobials, Antimicrobial resistance, Post antibiotic era
¨ Discovery of antimicrobials/antibiotics revolutionized treatment of infectious
¨ Soon realized bacteria could develop antimicrobial resistance
¨ AMR, a serious public health problem worldwide ¨ Infections could again become
serious health problem

Primary cause of AMR
¨ Resistance to antibiotic a natural phenomenon ¨ Indiscriminate and inappropriate use of antibiotics
resulted in rapid increase and spread of AMR

Appropriate use of medicine
¨ Patients receive the appropriate medicines, in doses that meet their own individual requirements, for an adequate period of time and at the lowest cost, both to them and the community (WHO)
¨ Definition true for antibiotic ¨ Inappropriate use of antibiotic when one or more of
or more of these conditions are not met

Appropriate antibiotic prescribing & inappropriateness in antibiotic use I. Prescriber ¨ Appropriate indication
¨ Appropriate antibiotic
¨ Appropriate patient
¨ Appropriate information
2. Pharmacists ¨ Prescribe and dispense antibiotics in developing countries
3. Patients ¨ Incomplete doses
¨ Self-medication

How to evaluate & tackle inappropriate use of antibiotics? ¨ Surveillance/measure antibiotic use
(inappropriateness) ¨ Investigating the reasons and factors underlying ¨ Identify the barriers to behaviour change ¨ Suitable and sustainable interventions ¨ Implementing and evaluating interventions

How far have we come? Developed country settings
¨ Extensive surveillance programs to track pattern of antibiotic use and AMR over time
¨ Swedish Program – STRAMA ¨ European Program – ESAC and EARSS ¨ Qualitative studies and intervention programs to
check antimicrobial misuse ¨ ASPs in U.S.A

How far have we come? Developing country settings
¨ Ability to undertake extensive surveillance is lacking ¨ No quality database for antibiotic use ¨ Problem of AMR has little recognition ¨ Fragmented data available (high use of AB) ¨ A reproducible and sustainable surveillance
methodology needed for quantifying antibiotic use and resistance in the community
![Page 10: stGlobal Forum on Bacterial Infections · Presentation outline ! Setting the scene ! Appropriate use of antibiotic ! Inappropriate use of antibiotic !

Steps in right direction…
¨ WHO collaborated 5 pilot projects to develop validated reproducible and sustainable surveillance methodology for AB use (2002-05)
¨ Refined a methodology by conducting patient exit interviews
¨ II phase of the study ( 2007- 2008), New Delhi
expanded the established methodology to a detailed community surveillance of antibiotic use

Moving ahead…..
¨ The surveillance system successfully captured the pattern of antibiotic use (newer AB used)
¨ Repeat survey could catch the change in trend of antibiotic use over a period of time
¨ Same methodology was used to study pattern of antibiotic (mis)use in URI and acute diarrhea
¨ Qualitative studies doctors, pharmacists, community, high school children

Next steps……. Globally
¨ Inappropriate antibiotic use in the community? YES ¨ Variation in health systems and stakeholders Each country needs to ¨ Measure, monitor antibiotic use ¨ Factors responsible at all stakeholders ¨ Committed program for intervention & monitor ¨ Required political commitment and multidisciplinary
team

Conclusions
¨ Antibiotics are indeed wonder drugs ¨ Use antibiotics judiciously ¨ Save the newer generations of antibiotics for next
generations and severely ill patients
