Inter- and Intraoperator Variability in Measurement of On-Site CT-derived Fractional Flow Reserve Based on Structural and Fluid Analysis: A Comprehensive Analysis.

Purpose: To measure the inter- and intraobserver variability among operators of varying expertise in conducting CT-derived fractional flow reserve (CT FFR) measurements on-site by using structural and fluid analysis and to evaluate differences in reproducibility between two different training methods for end users.

Materials And Methods: This retrospective analysis of the prospectively enrolled cohort included 22 symptomatic patients who underwent both 320-detector row coronary CT angiography and catheter-derived fractional flow reserve (FFR) within 90 days. Thirteen operators of varying expertise were assigned to one of two training arms: arm 1, on-site training by a specialist in CT FFR technology; arm 2, self-training through use of written materials.

The Ideal Hospital Discharge Summary: A Survey of U.S. Physicians.

Background: Hospital discharge summaries enable communication between inpatient and outpatient physicians. Despite existing guidelines for discharge summaries, they are frequently suboptimal.

Objective: The aim of this study was to assess physicians' perspectives about discharge summaries and the differences between summaries' authors (hospitalists) and readers (primary care physicians [PCPs]).
