Despite increased utilization of laboratory, radiologic imaging, and scoring systems, negative appendectomy (NA) rates in children remain above 3% nationwide. We reviewed the clinical data of patients undergoing appendectomy to further reduce our NA rate. ⋯ Absence of an elevated WBC count is a risk factor for NA. Withholding appendectomy for WBC counts <9000 and 8000 per µL reduces the NA rate to 0.6% and 1.2%, respectively. Missed true appendicitis in patients with normal WBC counts can be mitigated by a trial of observation in those presenting with early symptom onset.

In recent years, the focus on patient safety and housestaff supervision has led to a steady increase in institutions providing 24/7 in-hospital (also known as in-house, henceforth referred to as IH) coverage by pediatric intensivists. Effects of this increased attending physician presence on education of pediatric housestaff have not been studied. We hypothesized that IH coverage would decrease perceived autonomy of housestaff and negatively affect their preparedness to be independent attending physicians on completion of training. ⋯ Pediatric intensivists and housestaff express concern regarding the preparation of housestaff training in a 24/7 IH attending model. An important priority for institutions using or considering a 24/7 IH attending coverage model is the balance between adequate housestaff supervision and autonomy.

Comparative effectiveness of empiric antibiotics for community-acquired pneumonia.
Narrow-spectrum antibiotics are recommended as the first-line agent for children hospitalized with community-acquired pneumonia (CAP). There is little scientific evidence to support that this consensus-based recommendation is as effective as the more commonly used broad-spectrum antibiotics. The objective was to compare the effectiveness of empiric treatment with narrow-spectrum therapy versus broad-spectrum therapy for children hospitalized with uncomplicated CAP. ⋯ Compared with broad-spectrum agents, narrow-spectrum antibiotic coverage is associated with similar outcomes. Our findings support national consensus recommendations for the use of narrow-spectrum antibiotics in children hospitalized with CAP.

For children with cyanotic congenital heart disease or acute hypoxemic respiratory failure, providers frequently make decisions based on pulse oximetry, in the absence of an arterial blood gas. The study objective was to measure the accuracy of pulse oximetry in the saturations from pulse oximetry (SpO2) range of 65% to 97%. ⋯ Previous studies on pulse oximeter accuracy in children present a single number for bias. This study identified that the accuracy of pulse oximetry varies significantly as a function of the SpO2 range. Saturations measured by pulse oximetry on average overestimate SaO2 from CO-oximetry in the SpO2 range of 76% to 90%. Better pulse oximetry algorithms are needed for accurate assessment of children with saturations in the hypoxemic range.
