Obstructive sleep apnea as a risk factor after shoulder arthroplasty

Area of Science:

• Orthopaedic Surgery
• Sleep Medicine
• Health Services Research

Background:

• Obstructive sleep apnea (OSA) is increasingly screened for in perioperative settings.
• Limited evidence exists on OSA's impact on shoulder arthroplasty outcomes.
• This study investigates OSA's association with complications, length of stay, and costs.

Purpose of the Study:

• To determine if patients with OSA face higher risks after shoulder arthroplasty.
• To analyze the effect of OSA on postoperative complications, hospital stay duration, and costs.
• To inform perioperative screening protocols for shoulder arthroplasty patients.

Main Methods:

• Analysis of 22,988 patients undergoing shoulder arthroplasty using the Nationwide Inpatient Sample (NIS).
• Comparison of 1,983 patients with OSA against those without OSA.
• Multivariate logistic regression modeling to assess outcomes.

Main Results:

• No significant difference in in-hospital mortality or complications (including PE) between OSA and non-OSA groups.
• No increased postoperative charges for patients with OSA.
• Shorter average length of stay for patients with OSA (2.61 days vs. 2.91 days).

Conclusions:

• OSA is not a significant risk factor for in-hospital morbidity or mortality after shoulder arthroplasty.
• Current screening practices for OSA in this patient population may warrant re-evaluation.
• Further research is needed to optimize patient outcomes and manage screening costs.
