Abstract 13010: Trends and Predictors in Noninvasive and Invasive Ventilation in Patients With Heart Failure

Background: Mechanical ventilation in heart failure. However, trends and predictors of mechanical ventilation in heart failure are not well defined. Methods: We analyzed patients in the Nationwide Inpatient Sample (NIS) between 2002-2011 with primary discharge diagnosis of Heart Failure (CHF) and procedure diagnosis of noninvasive and invasive mechanical ventilation. Primary outcome was trend in noninvasive and invasive ventilation in CHF. Secondary outcome was predictors of mechanical ventilation in heart failure and their outcomes. Results: Among 10,475,928 weighted discharges with primary diagnosis of CHF, 532,701 discharges underwent mechanical ventilation. Among these patients 272,806(2.6%) had noninvasive while 259,894(2.5%) had invasive ventilation. We saw steady increase in use of mechanical ventilation over the last ten years (4.9% in 2002 to 7.1% in 2011,P<0.001). This was driven by steady increase in rates of noninvasive ventilation (1.1% in 2002 to 5.2% in 2011, p<0.001) with decline in rates ...
