Derivation and Validation of Two Decision Instruments for Selective Chest CT in Blunt Trauma: A Multicenter Prospective Observational Study (NEXUS Chest CT).
Unnecessary diagnostic imaging leads to higher costs, longer emergency department stays, and increased patient exposure to ionizing radiation. We sought to prospectively derive and validate two decision instruments (DIs) for selective chest computed tomography (CT) in adult blunt trauma patients. ⋯ We prospectively derived and validated two DIs (Chest CT-All and Chest CT-Major) that identify blunt trauma patients with clinically significant thoracic injuries with high sensitivity, allowing for a safe reduction of approximately 25%-37% of unnecessary chest CTs. Trauma evaluation protocols that incorporate these DIs may decrease unnecessary costs and radiation exposure in the disproportionately young trauma population.

Determination of radiography requirement in wrist trauma.
The purpose of this study was to evaluate predetermined physical examination and function tests recommended to identify severe injury among patients presenting with wrist injury to the emergency department and to establish a reliable clinical decision rule capable of determining the need for radiography in wrist injuries. ⋯ The presence of one of these examination findings increases the likelihood of fracture and is adequate to recommend wrist radiography. In addition, there is a strong possibility of radiography being unnecessary if all 4 test results are negative in patients presenting with wrist injury, potentially preventing many nonessential radiographs being performed.

Minimal clinically important differences in the Edmonton Symptom Assessment Scale in cancer patients: A prospective, multicenter study.
The Edmonton Symptom Assessment Scale (ESAS) is widely used for symptom assessment in clinical and research settings. A sensitivity-specificity approach was used to identify the minimal clinically important difference (MCID) for improvement and deterioration for each of the 10 ESAS symptoms. ⋯ ESAS was responsive to change. The optimal cutoffs were ≥1 point for improvement and ≤-1 point for deterioration for each of the 10 symptoms. Our findings have implications for sample size calculations and response determination.
