Data Impact Challenge II Question 2

Question 2:  What is the current antimicrobial consumption in a particular sector/unit/common condition? Are there particular outliers if we compare patient consumption, and what should we expect to see?

Drug-resistant infections are increasing as microbes adapt to the overuse of antimicrobials, resulting in significant morbidity and mortality. It is estimated that as much as 50% of antimicrobial usage may be unnecessary. Promoting prudent antimicrobial use in Canadian hospitals and healthcare organizations is essential to addressing antibiotic resistance. In order to determine which sectors/units/common conditions are at greatest risk of antimicrobial resistance and where we can improve inappropriate use and prescribing, we must first have an understanding of the current state of antimicrobial consumption. Having data which can inform us of current state, and which can be used for benchmarking will further this objective.


This question received four responses from three provinces: BC, Manitoba, and Ontario. Together the responses covered hundreds of millions of patient days.

Guiding Specifications

What is the antimicrobial consumption as expressed in DDD (defined daily dose) per 1000 patient days for each type of patient sector/unit/common condition? Sectors could be defined as: ambulatory care, acute care, and complex continuing care and rehabilitation. Unit can be defined: intensive care, surgical care, internal medicine. Common conditions can be defined as UTI (urinary tract infection), URTI (upper respiratory tract infections), pneumonia, skin and soft tissue infection (e.g. cellulitis).

The ideal response would be to provide consumption DDD/1000 patient day for a sector/unit/ common condition.
