Skip to 0 minutes and 5 secondsSo you know a little more about DDDs as a metric. You've had a look at how to use DDDs. And although they are not perfect, they are often used to monitor antimicrobial stewardship programmes in a hospital, and to assess the impact of interventions aimed at improving the quality of prescribing in a hospital. There is a drawback, of course though, and that is that whilst they do measure the quantity of antibiotic prescribing, I do wonder sometimes, to what extent that really reflects the quality of antibiotic prescribing. So the quantitative data will tell us how much antibiotic we're using, but it doesn't tell us why it's being used, or whether that use is appropriate.

So you know about using DDDs as a metric

You have experienced working with DDDs.

Although far from perfect they are commonly used to measure trends in antibiotic use in antimicrobial stewardship programmes and monitor the impact of interventions aimed at improving the quality of antibiotic use.

The key drawback is that whilst this approach will tell us how much antibiotic is being used it does not relate directly to the assessment of the quality of prescribing as we don’t know from this data why antibiotics are being used and whether the use is appropriate.

We will explore this in the next step.
