Abstract
Introduction:
We performed this study to quantify resources required by mechanically ventilated patients with hypoxemia after critical care transport (CCT) and to assess short-term clinical outcomes.
Methods:
We performed a retrospective review of transports of patients with severe hypoxemic respiratory failure from referring hospitals to 3 tertiary care hospitals to assess the outcomes including in-hospital mortality, ventilator days, intensive care unit length of stay (LOS), hospital LOS, disposition, and reported neurologic status on hospital discharge as well as medical interventions specific to acute respiratory failure and critical care.
Results:
Of 230 patients transported with hypoxemic respiratory failure, 152 survived to hospital discharge, for a mortality rate of 34.5%, despite a predicted mortality of 64% by Acute Physiology and Chronic Health Evaluation II (APACHE II) score. Twenty-five percent of patients were treated with neuromuscular blockade, 10.1% received inhaled pulmonary vasodilators, and extracorporeal membrane oxygenation was initiated in 2.6%.
Conclusions:
In this cohort with hypoxemic respiratory failure transported to tertiary care facilities, patients had a mortality rate comparable to patients with acute respiratory distress syndrome treated with best practices and a mortality rate lower than predicted based on APACHE-II score. The risks of CCT are outweighed by the benefits of transfer to a tertiary care facility, and pretransport hypoxemia should not be used as an absolute contraindication to transport.
