Special Report From the Society for the Advancement of Blood Management: The Choosing Wisely Campaign.
Over 7 years ago, the American Board of Internal Medicine Foundation (ABIM) created the national Choosing Wisely campaign with the purpose of encouraging active dialogue between health care providers and patients, focusing on appropriateness, quality care, and resource management. This special communication from the Society for the Advancement of Blood Management (SABM) serves to highlight the society's recent participation in the Choosing Wisely campaign, encouraging sensible dialogue between clinicians and our patients with the intent to promote patient-centered, evidence-based care. The article addresses the rationale and supportive data for the 5 SABM Choosing Wisely recommendations.

Comparative StudyComparison of Broadband and Discrete Wavelength Near-Infrared Spectroscopy Algorithms for the Detection of Cytochrome aa3 Reduction.
Cytochrome aa3, the terminal component of the electron transport chain, absorbs near-infrared radiation (NIR) differentially depending on its oxidation state (Cytox), which can in theory be measured using near-infrared spectroscopy (NIRS) by relating light absorption at specific wavelengths to chromophore concentrations. Some NIRS algorithms use discrete wavelengths, while others analyze a band of NIR (broadband NIRS). The purpose of this study was to test the ability of discrete wavelength and broadband algorithms to measure changes in Cytox (primary outcome), and to determine whether or not a discreet wavelength NIRS algorithm could perform similarly to a broadband NIRS algorithm for the measurement of Cytox in a staged hypoxia-cyanide model (hypoxia and cyanide have oppositional effects on tissue saturation, but both cause cytochrome reduction). ⋯ The broadband and 10 wavelength algorithm were able to accurately track changes in Cytox for all experiments.
