Cutting Down on Unnecessary Antibiotics for Pink Eye

TOPLINE:

More than two thirds of children with conjunctivitis received antibiotics within a day of their initial ambulatory care visit; however, follow-up visits and new antibiotic dispensations were rare regardless of treatment, suggesting that not receiving antibiotics may not lead to additional healthcare use.

METHODOLOGY:

• Researchers evaluated the frequency of topical antibiotic treatment and its association with subsequent healthcare use among commercially insured children with acute infectious conjunctivitis in the United States.
• This cohort study analyzed data from the 2021 MarketScan Commercial Claims and Encounters Database, including 44,793 children with conjunctivitis (median age, 5 years; 47% girls) and ambulatory care encounters.
• The primary exposure was a topical antibiotic prescription dispensed within 1 day of an ambulatory care visit, with outcomes assessed 2-14 days after the visit.
• The primary outcomes were ambulatory care revisits for conjunctivitis and same-day dispensation of a new topical antibiotic, and secondary outcomes included emergency department revisits and hospitalizations.

TAKEAWAY:

• Topical antibiotics were dispensed within a day of an ambulatory care visit in 69% of the cases; however, they were less frequently dispensed following visits to eye clinics (34%), for children aged 6-11 years (66%), and for those with viral conjunctivitis (28%).
• Ambulatory care revisits for conjunctivitis within 2 weeks occurred in only 3.2% of children who had received antibiotics (adjusted odds ratio [aOR], 1.11; 95% CI, 0.99-1.25).
• Similarly, revisits with same-day dispensation of a new antibiotic were also rare (1.4%), with no significant association between antibiotic treatment and revisits (aOR, 1.10; 95% CI, 0.92-1.33).
• Hospitalizations for conjunctivitis occurred in 0.03% of cases, and emergency department revisits occurred in 0.12%, with no differences between children who received antibiotics and those who did not.

IN PRACTICE:

“Given that antibiotics may not be associated with improved outcomes or change in subsequent healthcare use and are associated with adverse effects and antibiotic resistance, efforts to reduce overtreatment of acute infectious conjunctivitis are warranted,” the authors wrote.

SOURCE:

The study was led by Daniel J. Shapiro, MD, MPH, of the Department of Emergency Medicine at the University of California, San Francisco, and published online on June 27, 2024, in JAMA Ophthalmology.

LIMITATIONS:

The major limitations of the study included the inability to distinguish scheduled visits from unscheduled revisits, incomplete clinical data such as rare complications of conjunctivitis, and the inability to confirm the accuracy of the coded diagnosis of infectious conjunctivitis, especially in children who did not receive a thorough eye examination.

DISCLOSURES:

This study did not declare receiving funding from any sources. One author reported receiving grants from several sources outside the submitted work.
