An initial step toward improving outcomes for preterm infants Very preterm infants have poor neuro-cognitive outcomes relative to term infants for multiple reasons, including injury and altered brain development. However, a major societal challenge is the consistent observation that poor outcomes correlate better with socioeconomic status of the mother than with problems the infant may have had following delivery. Furthermore, prematu- rity is increased in disadvantaged populations. Intervention pro- grams are conceptually attractive, but have not been consistently successful. Koldewijn et al have now demonstrated that repeated intensive interventions to improve self-regulatory competence after birth improved developmental and behavioral assessments at 6 months of age relative to a randomized group of control infants. It will be essential to determine if these benefits detected at 6 months persist and contribute to improved long-term out- comes. —Alan H.

Testing in the treatment group was performed at the time of triage (before evaluation by a physician), and results were recorded on the patient’s chart. Outcomes assessed in the intervention and control groups were ED tests ordered, length of stay, prescription of an antibiotic, and then post-ED visit to a medical provider, performance of ancillary test(s), and prescription of an antibiotic. With 200 children’s data analyzed, the only outcome measure significantly affected by early, rapid testing was reduction in prescription of an antibiotic after ED discharge. It is possible that several caveats of the study design and performance “washed out” other potential beneficial effects of early testing for a viral etiology of illness (eg, number of test results not back before ED discharge in the intervention group, tests ordered by physician’s choice in the control group). Multi-viral rapid testing (RSV, influenza, parainfluenza, and adenovirus) confirmed viral etiology in 60% of subjects in this study. Even if the decrease in antibiotic prescriptions sub- sequent to the ED visit was the only benefit of testing, it raises a possible new strategy in the battle against overuse of antibiotics. —Sarah S.

n initial step toward improvingutcomes for preterm infants

Very preterm infants have poor neuro-cognitive outcomeselative to term infants for multiple reasons, including injury andltered brain development. However, a major societal challenge ishe consistent observation that poor outcomes correlate betterith socioeconomic status of the mother than with problems the

nfant may have had following delivery. Furthermore, prematu-ity is increased in disadvantaged populations. Intervention pro-rams are conceptually attractive, but have not been consistentlyuccessful. Koldewijn et al have now demonstrated that repeatedntensive interventions to improve self-regulatory competencefter birth improved developmental and behavioral assessmentst 6 months of age relative to a randomized group of controlnfants. It will be essential to determine if these benefits detectedt 6 months persist and contribute to improved long-term out-omes.

arly rapid diagnostic viral tests in themergency department setting

Doan et al from Vancouver, British Columbia, performedprospective, randomized, controlled intervention trial of per-

ormance of multi-viral rapid diagnostic testing in children 3 to6 months of age brought to the emergency department (ED)ith febrile respiratory tract illnesses. Testing in the treatmentroup was performed at the time of triage (before evaluation byphysician), and results were recorded on the patient’s chart.utcomes assessed in the intervention and control groups wereD tests ordered, length of stay, prescription of an antibiotic,

nd then post-ED visit to a medical provider, performance ofncillary test(s), and prescription of an antibiotic. With 200hildren’s data analyzed, the only outcome measure significantlyffected by early, rapid testing was reduction in prescription of anntibiotic after ED discharge. It is possible that several caveats ofhe study design and performance “washed out” other potentialeneficial effects of early testing for a viral etiology of illness (eg,umber of test results not back before ED discharge in the

ntervention group, tests ordered by physician’s choice in theontrol group).

Multi-viral rapid testing (RSV, influenza, parainfluenza,nd adenovirus) confirmed viral etiology in � 60% of subjects inhis study. Even if the decrease in antibiotic prescriptions sub-equent to the ED visit was the only benefit of testing, it raisespossible new strategy in the battle against overuse of antibiotics.

ut a major concern because of their long-term outcomes. In thisssue of The Journal, Glass et al provide precise estimates foreizure occurrence after term birth using a California data set ofver 2 million births.
