Outpatient antibiotic use linked to superbug infection.
A recent study has identified outpatient antibiotic use as a primary risk factor for acquiring a superbug. One of the most commonly reported indications for patient antibiotic use in the study was dental surgery.
Clostridium difficile is an infection which is typically associated with antibiotic use in hospital patients. Increasingly however, there are cases being reported among outpatients. According to the Centers for Disease Control and Prevention (CDC) 41% of all C. difficile cases occurred outside of hospitals in the USA.
In order to identify possible risk factors, researchers interviewed 452 participants who had tested positive for C. difficile as well as a control group who had not had the infection. They found that larger percentages of patients with the infection had visited healthcare centres and had taken antibiotics, compared with the control group.
One of the most common indications for outpatient antibiotic use amongst those affected was dental surgery, though ear, sinus and respiratory infections were the most common. There were also some instances where dental cleaning was the reported indication. Previous studies have suggested that over 50% of outpatient antibiotic prescriptions are unnecessary. The study concludes that continued efforts to promote outpatient antibiotic stewardship are required.
