Antibiotic Prophylaxis for Children With Sickle Cell Anemia

Area of Science:

• Pediatric Hematology
• Infectious Disease Prevention
• Public Health

Background:

• Children with sickle cell anemia (SCA) face a heightened risk of invasive pneumococcal disease.
• Antibiotic prophylaxis is a proven method to significantly reduce this risk.

Purpose of the Study:

• To determine the proportion of children with SCA receiving at least 300 days of antibiotic prophylaxis annually.
• To identify predictors associated with receiving adequate antibiotic prophylaxis in this population.

Main Methods:

• A retrospective cohort study analyzed Medicaid claims data from children aged 3 months to 5 years with SCA in six US states (2005-2012).
• Antibiotic receipt was identified via filled prescription claims, with ≥300 days assessed annually.
• Logistic regression with generalized estimating equations identified predictors such as age, sex, year, state, and healthcare utilization.

Main Results:

• Out of 2821 children, only 18% received ≥300 days of antibiotic prophylaxis.
• Each additional sickle cell disease-related outpatient visit (OR=1.01) and well-child visit (OR=1.08) was associated with increased odds of receiving adequate prophylaxis.

Conclusions:

• Despite established benefits, antibiotic prophylaxis rates for children with SCA remain low.
• Healthcare encounters present opportunities for intervention, but social factors influencing adherence must also be addressed.
