Abstract

Purpose:

Data regarding best practices for ventilator management strategies that improve outcomes in acute respiratory distress syndrome (ARDS) are readily available. However, little is known regarding processes to ensure compliance with these strategies. We developed a goal-directed mechanical ventilation order set that included physician-specified lung-protective ventilation and oxygenation goals to be implemented by respiratory therapists (RTs). We sought as a primary outcome to determine whether an RT-driven order set with predefined oxygenation and ventilation goals could be implemented and associated with improved adherence with best practice.

Methods:

We evaluated 1302 patients undergoing invasive mechanical ventilation (1693 separate episodes of invasive mechanical ventilation) prior to and after institution of a standardized, goal-directed mechanical ventilation order set using a controlled before-and-after study design. Patient-specific goals for oxygenation partial pressure of oxygen in arterial blood (Pao ₂), ARDS Network [Net] positive end-expiratory pressure [PEEP]/fraction of inspired oxygen [Fio ₂] table use) and ventilation (pH, partial pressure of carbon dioxide) were selected by prescribers and implemented by RTs.

Results:

Compliance with the new mechanical ventilation order set was high: 88.2% compliance versus 3.8% before implementation of the order set (P < .001). Adherence to the PEEP/Fio ₂ table after implementation of the order set was significantly greater (86.0% after vs 82.9% before, P = .02). There was no difference in duration of mechanical ventilation, intensive care unit (ICU) length of stay, and in-hospital or ICU mortality.

Conclusions:

A standardized best practice mechanical ventilation order set can be implemented by a multidisciplinary team and is associated with improved compliance to written orders and adherence to the ARDSNet PEEP/Fio ₂ table.
