The Pennsylvania Patient Safety Authority received a request for guidelines and adverse event information about prolonged prone positioning (i.e., 16 or more consecutive hours) for patients with acute respiratory distress syndrome (ARDS). While early application of prolonged prone positioning for patients with severe ARDS has shown a reduction in patient mortality,1,2 no formal evidence-based guidelines were found in the literature; however, there are contraindications associated with this intervention.

Before prone positioning is implemented, contraindications to consider include increased intracranial pressure, spinal instability, severe hemodynamic instability, recent abdominal surgery or open abdominal wounds, unstable fractures, pregnancy, eye trauma or injury, recent pacemaker insertion, maxillofacial injuries, tracheostomy or tracheal surgery, and extracorporeal membrane oxygenation.3-5

Authority analysts queried the Pennsylvania Patient Safety Reporting System (PA-PSRS) database for event narratives from the most recent 10 calendar years, 2005 through 2014, associated with prone positioning (i.e., keywords “prone” or “proning”) used as an intervention for patients with ARDS, respiratory failure, or pneumonia. The search returned 167 event reports. Pressure ulcers accounted for the majority (82.6%, n = 138) of events reported, which is consistent with the literature.1,2,6

Other events related to prone positioning identified in PA-PSRS reports or in the literature include unintended extubations; broken or displaced teeth; skin tears, lacerations, or abrasions; edema of the face, eyes, or tongue; disconnected tubes or intravenous lines; ventilator-associated pneumonia; cardiac events; pneumothorax; and ischemic optic neuropathy.1,2,6,7 Authority analysts were unable to determine the relative risks for these events because PA-PSRS does not collect data on the total incidence and duration of prone positioning.
