Can paramedics accurately identify patients who do not require emergency department care?

Objective: To determine whether paramedics can identify patients contacting 9-1-1 who do not require emergency department (ED) care.

Methods: The setting was an urban county with a two-tiered, dual response to 9-1-1 calls comprising eight local fire departments with advanced life support capabilities and a private advanced life support 9-1-1 agency with primary transport responsibilities (approximately 39,000 of the 78,000 total system patient transports in this county per year). The study population consisted of consecutive patients transported by a private transporting paramedic agency.

High yield criteria for obtaining non-trauma chest radiography in the adult emergency department population.

To develop a clinical decision rule for predicting significant chest radiography abnormalities in adult Emergency Department (ED) patients, a prospective, observational study was conducted of consecutive adults (>or=18 years old) who underwent chest radiography for nontraumatic complaints at an urban ED with an annual census of 85,000. The official radiologist interpretation of the film was used as the gold standard for defining radiographic abnormalities. Using predefined criteria and author consensus, patients were divided into two groups: those with clinically significant abnormalities (CSA) and those with either normal or nonclinically significant abnormalities.
