Nonurgent pediatric emergency department visits: Care-seeking behavior and parental knowledge of insurance.

OBJECTIVES The goals of this study were to describe the factors associated with utilization of emergency services for nonurgent illnesses by insured children in a pediatric emergency department (PED) and to assess parental knowledge of their insurance and its influence on care-seeking behaviors. METHODS We conducted a prospective, descriptive survey of parents of insured children evaluated for nonurgent illnesses in an urban PED. RESULTS A total of 251 surveys were completed. The primary reason chosen by the parent for the PED visit was convenience in 62.8% of cases, a perceived true emergency in 33.6%, and lack of other access to a physician in 3.6%. Parents choosing the PED for perceived emergencies were more likely to state that the illness was life threatening or required hospital admission than those who came because of convenience (33/84 vs. 28/157; < 0.001). Only 38.7% stated that they were educated as to what problems are considered emergencies by their insurance carriers. PED referrals for nonurgent complaints are required by the insurance carrier for 74.9% of the population; however, only 37.2% of the parents stated that referrals were necessary. Primary care physician (PCP) contact was made prior to the visit by 45.4% of parents. Of those who called the PCP, 72.6% stated that they were referred to the PED. Of the parents who believed that a referral was required, those stating that the problem was an emergency were more likely to have contacted the PCP than those who came because of convenience (27/37 vs. 22/46; < P 0.037).CONCLUSIONS Parents frequently do not understand their insurance coverage as it relates to emergency care utilization. This lack of knowledge influences their care-seeking behaviors for nonurgent illnesses. Convenience is a significant factor in PED utilization for nonurgent complaints.

Utility of the serum C-reactive protein for detection of occult bacterial infection in children.

OBJECTIVE: To assess the utility of serum C-reactive protein (CRP) as a screen for occult bacterial infection in children. METHODS: Febrile children ages 3 to 36 months who visited an urban children's hospital emergency department and received a complete blood cell count and blood culture as part of their evaluation were prospectively enrolled from February 2, 2000, through May 30, 2001. Informed consent was obtained for the withdrawal of an additional 1-mL aliquot of blood for use in CRP evaluation. Logistic regression and receiver operator characteristic (ROC) curves were modeled for each predictor to identify optimal test values, and were compared using likelihood ratio tests. RESULTS: Two hundred fifty-six patients were included in the analysis, with a median age of 15.3 months (range, 3.1-35.2 months) and median temperature at triage 40.0 degrees C (range, 39.0 degrees C-41.3 degrees C). Twenty-nine (11.3%) cases of occult bacterial infection (OBI) were identified, including 17 cases of pneumonia, 9 cases of urinary tract infection, and 3 cases of bacteremia. The median white blood cell count in this data set was 12.9 x 10(3)/ micro L [corrected] (range, 3.6-39.1 x10(3)/ micro L) [corrected], the median absolute neutrophil count (ANC) was 7.12 x 10(3)/L [corrected] (range, 0.56-28.16 x10(3)/L) [corrected], and the median CRP level was 1.7 mg/dL (range, 0.2-43.3 mg/dL). The optimal cut-off point for CRP in this data set (4.4 mg/dL) achieved a sensitivity of 63% and a specificity of 81% for detection of OBI in this population. Comparing models using cut-off values from individual laboratory predictors (ANC, white blood cell count, and CRP) that maximized sensitivity and specificity revealed that a model using an ANC of 10.6 x10(3)/L [corrected] (sensitivity, 69%; specificity, 79%) was the best predictive model. Adding CRP to the model insignificantly increased sensitivity to 79%, while significantly decreasing specificity to 50%. Active monitoring of emergency department blood cultures drawn during the study period from children between 3 and 36 months of age showed an overall bacteremia rate of 1.1% during this period. CONCLUSIONS: An ANC cut-off point of 10.6 x10(3)/L [corrected] offers the best predictive model for detection of occult bacterial infection using a single test. The addition of CRP to ANC adds little diagnostic utility. Furthermore, the lowered incidence of occult bacteremia in our population supports a decrease in the use of diagnostic screening in this population.

Group B streptococcal retropharyngeal cellulitis in a young infant: a case report and review of the literature.

The diagnosis of retropharyngeal cellulitis and abscess, although most common in children under 6 years of age, is often misdiagnosed in the newborn or early infancy period. The clinical signs of drooling, neck swelling, dysphagia, and torticollis may be absent or not easily identifiable. The following case report details a 2 1/2-month-old infant who presented with fever and irritability, and was subsequently diagnosed with group B streptococcal retropharyngeal cellulitis. Retropharyngeal cellulitis and abscess should be considered in the differential diagnosis of infants and young children who present with fever and irritability, particularly when lumbar puncture results are normal. This case also serves to highlight a rare manifestation of late-onset group B steptococcal disease.
