supplementary information appendix for "global increase and geographic convergence in antibiotic consumption between 2000 and 2015" provides data on antibiotic consumption by country/region and sector from 2000–2015, sourced from iqvia midas. it includes methods for estimating defined daily doses (ddd) unit values for converting su to kg, using the atc/ddd index and other sources. for molecules without ddd unit values, estimates were made based on average values for each antibiotic class by route of administration. total global antibiotic use between 2000–2015 was estimated using population data from the world bank databank and average per capita consumption. for 2015–2030, three scenarios were predicted: scenario 1 assumes continued consumption at 2015 per capita rates; scenario 2 assumes continued growth at current rates; scenario 3 assumes convergence to the 2015 global median per capita rate by 2020. supplementary figures show changes in national antibiotic consumption rates and estimated total global consumption by income group. the correlation between esac-net and iqvia midas data was 93%. references are provided for methods used in estimating ddd unit values.supplementary information appendix for "global increase and geographic convergence in antibiotic consumption between 2000 and 2015" provides data on antibiotic consumption by country/region and sector from 2000–2015, sourced from iqvia midas. it includes methods for estimating defined daily doses (ddd) unit values for converting su to kg, using the atc/ddd index and other sources. for molecules without ddd unit values, estimates were made based on average values for each antibiotic class by route of administration. total global antibiotic use between 2000–2015 was estimated using population data from the world bank databank and average per capita consumption. for 2015–2030, three scenarios were predicted: scenario 1 assumes continued consumption at 2015 per capita rates; scenario 2 assumes continued growth at current rates; scenario 3 assumes convergence to the 2015 global median per capita rate by 2020. supplementary figures show changes in national antibiotic consumption rates and estimated total global consumption by income group. the correlation between esac-net and iqvia midas data was 93%. references are provided for methods used in estimating ddd unit values.
