Antibiotic prescribing and expenditures in outpatient adults in Greece, 2010 to 2013: evidence from real-world practice.

We provide a representative analysis of antibiotic prescribing, identify factors associated with broad-spectrum antibiotic prescribing and assess the costs associated with antibiotic use in adult outpatients in Greece. Outpatient antibiotic prescriptions for patients older than 19 years between 2010 and 2013 in Greece were extracted from the IMS Health Xponent database. Prescribing rate and total cost for prescribed antibiotics were calculated.
