National Trends in Incidence and Outcomes of Patients With Heart Failure Requiring Respiratory Support.
Abstract Despite increasing medical complexity in patients with heart failure (HF), there are limited data on incidence and outcomes for patients with HF needing respiratory support. This study sought to examine contemporary trends of respiratory support strategies among patients with HF. Using the National Inpatient Sample, we identified adults aged greater than 18 years hospitalized with a primary diagnosis of HF. We assessed for trends in the use of invasive mechanical ventilation (IMV) and non-invasive ventilation (NIV), length of stay (LOS), hospital costs, and in-hospital mortality. From 2002-2014, we identified 9,508,768 HF hospitalizations, which included 202,340 (2.13%) and 257,549 (2.71%) patients that required IMV and NIV, respectively. Over the study period, the proportion of HF patients requiring IMV significantly decreased (3.25% in 2002 to 1.56% in 2014) while the use of NIV significantly increased from 0.95% to 7.25% (ptrend
