Impact of obstructive sleep apnea on perioperative complications among patients undergoing hysterectomy: a population-based analysis.

In this study data on patients who underwent a hysterectomy between 2006 and 2014 from a large nationwide database (n = 459,508) was investigated. OSA patients (identified by ICD-9 CM codes) were compared to non-OSA patients regarding perioperative outcomes: cardiac, central-nervous, gastrointestinal, genitourinary, renal, respiratory, and thromboembolic complications; as well as opioid prescription, need for blood transfusion, cost of hospitalization, length of stay and ICU admission. Results showed that among patients undergoing hysterectomies, OSA was associated with substantially increased risk of complications and modestly increased resource utilization. Therefore, further research is needed to assess perioperative care strategies to improve outcomes in patients with OSA.
