The quantum of use is best described by defined daily dose. Defined daily doses (DDDs) of antimicrobials prescribed per 100 bed days are a good measure of antimicrobial consumption. The DDD methodology converts and standardises readily available product quantity data into crude estimates of clinical exposure to medicines. The DDD is the assumed average maintenance dose for the medication's main indication. The study shows a consistently very high increase in the consumption of Meropenem and Ceftriaxone while there is no significant change in the consumption of Metronidazole, Tobramycin, and Vancomycin. The increase in expenditure due to antibiotic usage from 2011 to 2012 was 23% while the increase from 2012 to 2013 was 17%. It has also identified drugs like Meropenem and Piper...
