Pc. Ferrera et al., NEONATAL FEVER - UTILITY OF THE ROCHESTER CRITERIA IN DETERMINING LOW-RISK FOR SERIOUS BACTERIAL-INFECTIONS, The American journal of emergency medicine, 15(3), 1997, pp. 299-302
The purpose of this study was to test the utility of the Rochester cri
teria in determining which febrile neonates are at low risk for seriou
s bacterial infections (SBI). This was a retrospective study over a 5-
year period of 134 patients younger than 29 days old with fever withou
t a source evaluated in the emergency department. Results of urinalysi
s, lumbar puncture, peripheral white blood cell count, and cultures of
blood, urine, cerebrospinal fluid, and stool were recorded. Of the 13
4 neonates, 71 were high-risk, 48 low risk, and 15 were not classifiab
le by the available data, Nineteen of the 71 high risk patients (26.8%
) had SBI (2 patients had 2 SBI). Three of the 48 low-risk neonates (6
.3%) had SBI (1 patient had 2 SBI). None of the 15 nonclassifiable pat
ients had SBI. Employing the Rochester criteria to the fully cultured
neonates who could be risk-stratified, the sensitivity, specificity, p
ositive predictive value, and negative predictive value were 86.4%, 46
.4%, 26.8%, and 93.8%, respectively. Although outpatient management of
febrile neonates may be feasible, a small percentage of neonates meet
ing low risk criteria will have a SBI. Copyright (C) 1997 by W.B. Saun
