The new guideline recommends that polysomnography be used for the diagnosis of obstructive sleep apnea in patients with significant cardiorespiratory disease or other complicating conditions. Home sleep apnea testing is recommended only for uncomplicated adult patients with increased risk of moderate to severe sleep apnea.
Research found that individual physicians' spending patterns have a limited impact on patient outcomes, with no difference in readmissions or mortality rates between low- and high-spending physicians. The study analyzed data from Medicare patients aged 65 and older who were hospitalized for nonelective conditions between 2011 and 2014.
