To examine the cost-effectiveness of a quantitative D-dimer assay for the evaluation of patients with suspected pulmonary embolism (PE) in an urban emergency department (ED). ⋯ In patients in whom PE is suspected, when CTA is available, even the most sensitive quantitative D-dimer assay is not likely to be cost-effective. When CTA is not available or if its performance is markedly degraded, use of the D-dimer assay has value in combination with CUS and a pulmonary imaging study. These conclusions may not hold for the larger domain of patients presenting to the ED with chest pain or shortness of breath in whom PE is one of many competing diagnoses.

To determine if blood cultures identify organisms that are not appropriately treated with initial empiric antibiotics in hospitalized patients with community-acquired pneumonia, and to calculate the costs of blood cultures and cost savings realized by changing to narrower-spectrum antibiotics based on the results. ⋯ Appropriate empiric antibiotics were administered in all bacteremic patients. Antibiotic regimens were rarely changed based on blood culture results, and the potential savings from changes were minimal.

The authors reviewed the evidence on performance improvement methods for increasing emergency department (ED) patient satisfaction to provide evidence-based suggestions for clinical practice. ⋯ There is modest evidence supporting a range of performance improvement interventions for improving ED patient satisfaction. Further work is needed before specific, evidence-based recommendations can be made regarding which process changes are most effective. Recommendations are made for improving the quality of performance improvement efforts in the ED setting.
