Table 4.
Multivariable post-operative outcomes and intraoperative and postoperative opioid use and difference in post-operative outcomes and opioid use by OSA risk group. The adjusted means/rates in each group and the adjusted difference in means/rates are presented. A positive difference indicates a higher adjusted rate or higher adjusted mean in the high-risk and diagnosed OSA group.
| Low or moderate risk of OSA (N=5286) | High-risk or diagnosed OSA (N=435) | Adjusted Difference | 95% CI | p value | |
|---|---|---|---|---|---|
| Length of stay for outpatient procedures, in hoursa | 3.24 | 3.30 | 0.063 | −0.33, 0.46 | 0.8 |
| Discharge time for AXR procedures, in hoursa | 10.9 | 11.1 | 0.25 | 0.01, 0.50 | 0.044 |
| Transfer to main hospital after surgery b | 0.47% | 0.60% | 0.12% | −0.37%, 0.61% | 0.6 |
| UCC visit within 30 days b | 4.2% | 5.6% | 1.4% | −0.68%, 3.4% | 0.15 |
| Readmission within 30 days b | 1.9% | 3.1% | 1.2% | −0.40%, 2.8% | 0.077 |
| Any intraoperative opioid usec | 99% | 98% | −0.60% | −2.1%, 0.87% | 0.3 |
| Any postoperative opioid usec | 61% | 60% | −1.3% | −6.9%, 4.3% | 0.6 |
Mean differences in length of stay and discharge time were adjusted for age, ASA, robotic surgery, type of anesthesia and surgery start time.
For transfer to the main hospital and UCC visit or readmission within 30 days, risk differences were adjusted for age, ASA, robotic surgery, type of anesthesia and procedure class.
Risk differences in use of any intraoperative or postoperative opioid use were adjusted for age, gender, BMI, surgical service and procedure class.
AXR= Ambulatory Extended Recovery
UCC= Urgent Care Center
