BackgroundAlthough noninvasive positive pressure ventilation (NPPV) improves outcomes in patients who have acute respiratory failure due to chronic obstructive pulmonary disease (COPD) or congestive heart failure (CHF), it may be underutilized outside the controlled trial setting.PurposeThe purpose of this study is to determine the proportion of patients who met criteria for a trial of NPPV but were emergently intubated and mechanically ventilated without receiving a trial of NPPV.MethodsWe retrospectively reviewed charts of patients who were intubated and ventilated or who received NPPV on admission to one intensive care unit and who had an intensive care unit admitting diagnosis of either exacerbation of COPD or CHF during the period from November 1998 to July 2003.ResultsOf the 243 patients who had an admitting diagnosis of COPD or CHF, 59 (24.3%) met explicit criteria for a trial of NPPV. Only 20 (33.9%) of 59 had a trial of NPPV. The remaining 39 (66%) of 59 did not receive a trial of NPPV and were intubated.InterpretationNearly two thirds of patients who appeared to meet criteria for NPPV did not receive a trial of this intervention. There is an opportunity to improve the use of NPPV in these patients. Systematic knowledge translation strategies such as guideline implementation and interactive educational interventions may optimize the appropriate use of NPPV.
