Tracking antibiotic consumption within a country is an important component of a national action plan.
The quantity of consumption can be measured at many different levels, for example at country, region, hospital/prescriber or farm level. It allows for informed decisions on where to focus efforts to reduce unnecessary use and can assist evaluation of initiatives. Information on antibiotic consumption at the national level is useful when formulating policies, developing formulary controls, or making decisions on prescribing guidelines or guidelines for prudent use in animals. Consumption data is further useful for benchmarking purposes and comparison between countries/regions/hospitals/farms.
Sources for data
A country’s total consumption can be measured as the value of its production plus imports minus the value of its exports . The following sources can be used to obtain information on antibiotic consumption:
- Total national imports
- National medicine agency procurement records
- Reimbursement data from insurance companies
- Drug importers, customs services and port authorities (during clearing processes)
- Drug sales volume from local manufacturers and wholesalers
- Point prevalence data on antibiotic consumption collected at health care or farm level
In many countries, accurate sales data on medicines are kept by government agencies responsible for pharmaceuticals. The focus is often financial, but accurate volume data may be associated. European countries that report consumption data to the European Surveillance of Antimicrobial Consumption Network (ESAC-Net) provide national sales and/or reimbursement data from health insurance systems . In other countries, volume data can be obtained from drug regulatory agencies, those responsible for which antibiotics have been registered for use in their jurisdiction.
Many countries have a national mechanism to track antibiotic production or import, but when such systems are lacking, drug wholesalers become a vital source of information on consumption. Often wholesalers are the only legal entity authorized to import antibiotics. Precise estimates on the quantity of antibiotics in circulation can be challenging to obtain as it is difficult to capture data on antibiotics entering the country through illegal routes .
For information on how to measure antibiotic consumption in health care, community and in the animal sector, see MEASURE: Consumption. How to examine if the correct antibiotic is used for the correct indication is described in MEASURE: Appropriate use.
