Manual vs Automatic Prone Positioning and Patient Outcomes in Acute Respiratory Distress Syndrome

Area of Science:

• Critical Care Medicine
• Respiratory Therapy
• Quality Improvement

Background:

• Prone positioning is a cornerstone therapy for moderate to severe acute respiratory distress syndrome (ARDS).
• Comparative outcome data between manual and automatic prone positioning techniques are lacking.
• A multidisciplinary team implemented a pronation quality improvement project to address this gap.

Purpose of the Study:

• To retrospectively compare patient outcomes between manual and automatic prone positioning in ARDS.
• To evaluate the impact of a pronation quality improvement initiative on clinical outcomes.
• To assess the cost-effectiveness of different prone positioning methods.

Main Methods:

• A retrospective, descriptive-comparative study analyzed 24 months of ARDS patient data.
• Data from 37 patients (16 manual, 21 automatic prone positioning) were analyzed.
• Descriptive and nonparametric statistical analyses were employed.

Main Results:

• Outcomes were comparable for time to initiation, discharge disposition, and length of stay.
• Manual prone positioning was associated with significantly fewer therapy interruptions (P = .005) and complications (P = .002).
• Pressure injuries were common, particularly on the head, thorax, and lower extremities in automatically pronated patients. Manual positioning yielded cost savings of $78,617 per patient.

Conclusions:

• Manual prone positioning demonstrates comparable efficacy to automatic methods with reduced risks and lower costs.
• Further research is recommended to definitively establish the superiority of manual prone positioning in ARDS management.
• The findings suggest potential benefits of manual prone positioning in resource-limited settings or for optimizing patient safety.
