Blood culture accuracy: discards from central venous catheters in pediatric oncology patients in the emergency department.

Introduction: Lack of specific guidelines regarding collection of blood for culture from central venous catheters (CVCs) has led to inconsistencies in policies among hospitals. Currently, no specific professional or regulatory recommendations exist in relation to using, reinfusing, or discarding blood drawn from CVCs before drawing blood for a culture. Repeated wasting of blood may harm immunocompromised pediatric oncology patients.

Vancomycin-resistant Enterococcus in pediatric oncology patients: balancing infection prevention and family-centered care.

In February 2007, we experienced an abrupt 8-fold increase in vancomycin-resistant Enterococcus (VRE)-positive pediatric hematology/oncology patients in isolation per day, peaking at 12 patients in isolation per day in June 2007. We enforced and expanded infection prevention practices and initiated a rigorous 6-month clearance process. After noting an eventual decrease, we modified clearance to a 3-month process, maintaining <1 patient/day in isolation by June 2009, subjectively improving family and staff satisfaction after this 2-year process.

Evaluation of indirect fluorescent antibody assays compared to rapid influenza diagnostic tests for the detection of pandemic influenza A (H1N1) pdm09.

Performance of indirect fluorescent antibody (IFA) assays and rapid influenza diagnostic tests (RIDT) during the 2009 H1N1 pandemic was evaluated, along with the relative effects of age and illness severity on test accuracy. Clinicians and laboratories submitted specimens on patients with respiratory illness to public health from April to mid October 2009 for polymerase chain reaction (PCR) testing as part of pandemic H1N1 surveillance efforts in Orange County, CA; IFA and RIDT were performed in clinical settings. Sensitivity and specificity for detection of the 2009 pandemic H1N1 strain, now officially named influenza A(H1N1)pdm09, were calculated for 638 specimens.
