Management of afebrile neonates with pustules and vesicles in a pediatric emergency department

摘要

Abstract Objectives To assess the management and outcomes of vesicles and pustules in afebrile neonates presenting to the pediatric emergency department. Methods Using International Classification of Diseases, Ninth Revision , codes, we identified patients 0‐60?days old presenting to our pediatric emergency department from 2008 to 2015 with a possible diagnosis of pustules or vesicles. We then used natural language processing followed by manual chart review to identify afebrile neonates with pustules or vesicles. We collected clinical data from the electronic medical record. We also assessed current practice patterns for neonatal pustules or vesicles using a survey administered to attending physicians. Results Of the 971 possible cases identified using International Classification of Diseases, Ninth Revision , codes for fluid‐filled lesions, only 64 patients had vesicles (n?=?9) and pustules (n?=?55). One‐third (22/64) of afebrile neonates with pustules and vesicles were admitted to the hospital and received empiric parenteral therapy. Admission, parenteral antibiotics, and antiviral therapy were more common in neonates presenting with vesicles than in those with pustules alone. Apart from 2 presumed blood culture contaminants, there were no positive blood or cerebrospinal fluid cultures. Two patients had positive urine cultures. Institutional survey data showed practice patterns consistent with these retrospective results. Conclusion Although one‐third of neonates with pustules and vesicles were admitted to the hospital and received parenteral therapy, there were no cerebrospinal fluid or blood infections or any confirmed evidence of herpes simplex virus disease. These findings suggest that afebrile, well‐appearing neonates presenting with pustules alone may not need a full serious bacterial infection examination. Larger studies are needed to confirm these findings and assess outcomes, especially in afebrile neonates with vesicles.
