Before culture results are back: how likely is each antibiotic to cover the pathogen of a patient like this one, in this ward, given the last 12 months of results and today's alerts.

Decision support only: coverage is the share of first isolates from similar patients that were susceptible (an organism not tested for a drug counts as not covered). It does not replace local treatment guidelines, allergy and severity assessment, or clinical judgement. The black tick on each bar is the coverage target; the bracket is the 95 % confidence interval.
