National Survey on the Emergency Department Management of Febrile Infants 29 to 60 Days Old With an Abnormal Urinalysis.

Objectives: Recent clinical practice guidelines recommend that decisions regarding lumbar puncture (LP) for febrile infants older than 28 days should no longer be based on urinalysis results, but rather independently determined by inflammatory markers and sometimes guided by shared decision-making (SDM). This study sought to assess management decisions for febrile infants aged 29 to 60 days with an abnormal urinalysis.

Methods: A scenario-based survey was sent to emergency department physicians at all 15 Canadian tertiary pediatric centers. Participants were asked questions regarding management decisions when presented with a well-appearing febrile infant in the second month of life with either an abnormal or normal urinalysis.

Results: Response rate was 50.2% (n = 116/231). Overall, few respondents would perform an LP based on either an abnormal or normal urinalysis alone (10.3% and 6.0%, respectively). However, regression analysis demonstrated that decisions regarding LP were influenced by urinalysis results ( P < 0.001), with respondents more likely to defer to inflammatory marker results for infants with a normal urinalysis result (57.8%) compared with those with an abnormal urinalysis (28.4%). Hospitalization (62.1%) and empiric antibiotic treatment by intravenous route (87.9%) were both frequent for low-risk infants with an abnormal urinalysis. Nearly half of respondents reported rarely (<25% of encounters) engaging families in SDM regarding LP decisions.

Conclusions: Knowledge translation initiatives reflecting current evidence should target use of inflammatory markers rather than urinalysis results to guide decisions regarding LP. Efforts emphasizing outpatient management with oral antibiotics and SDM for low-risk infants with an abnormal urinalysis could also further align management with current evidence and guidelines.
