Is Preoperative Administration of STOP-BANG Predictive of Adverse OSA Parameters?

To meet the military’s need to “care for all entrusted to our care”, the purpose of this study is to determine if the STOP-BANG score identifies and predicts TKA patients at risk for worsening OSA symptoms as determined by an nattended sleep study during the first three nights after surgery. 

The specific aim of this Phase I, observational cohort study is to obtain preliminary evidence to: 

1. Compare baseline and postoperative sleep apnea parameters (apnea hypopnea index (AHI), time  with oxygen saturation (SPO2) 90% & 85% [T90 & T85], lowest oxygen saturation [LSAT], & number of central apneas) based on STOP-BANG scores and categories (3, ≥3 to 5, or ≥5) in patients undergoing TKA.

The short-term outcome of this study is to obtain preliminary evidence for Phase II, a TSNRP grant proposal to recruit a larger sample. The overall short-term goal (Phase I and II) is to provide military nurses with the knowledge and data to implement changes in the management of intraoperative and postoperative care of TKA patients who screen positive for OSA by the STOP-BANG (who needs continuous end tidal CO2/SPO2 monitoring). Providing military nurses with evidence-based recommendations for the management of OSA in the long-term will improve patient safety, reduce complications,and decrease health-care costs.
