Americans with commercial health insurance are using antibiotics less frequently than they did several years ago, according to a new study by the Blue Cross Blue Shield Association, per The Washington Post.

Why it matters: The analysis reveals that doctors and patients are becoming more cautious of excessive antibiotic use, which research has shown breeds drug resistance and "superbug" bacteria. A study last year revealed roughly one-third of the antibiotics prescribed in outpatient settings were unnecessary.
