Compliance with guidelines for the medical care of first urinary tract infections in infants.

BACKGROUND No population-based studies have examined the degree to which practice parameters are followed for urinary tract infections in infants. OBJECTIVE To describe the medical care of children in their first year of life after a first urinary tract infection. METHODS Using Washington State Medicaid data, we conducted a retrospective cohort study of children with a urinary tract infection during their first year of life to determine how many of these children received recommended care based on the most recent guidelines from the American Academy of Pediatrics. Recommended care included timely anatomic imaging, timely imaging for reflux, and adequate antimicrobial prophylaxis. Multivariate logistic-regression models were used to evaluate if hospitalization for first urinary tract infection, young age at time of diagnosis, gender, race, primary language of parents, having a managed care plan, and rural location of household residence were associated with recommended care. RESULTS Less than half of all children diagnosed with a urinary tract infection in their first year of life received the recommended medical care. Children who were hospitalized for their first urinary tract infection were significantly more likely than children who were not hospitalized to receive anatomic imaging (relative risk [RR]: 1.38; 95% confidence interval [CI]: 1.20-1.57) and imaging for reflux (RR: 1.62; 95% CI: 1.34-1.90). CONCLUSIONS There is poor compliance with guideline-recommended care for first urinary tract infections in infants in a Medicaid population. Given the trend toward increased outpatient management of urinary tract infections, increased attention to outpatient imaging may be warranted.
