Relationship Between Continuous Symptomless Multi-Variable Apnea Prediction and OSA, Hypertension and Postoperative Complications.
| Outcome | sMVAP effect | |||
|---|---|---|---|---|
| Unconditional | Conditionala | |||
| OR (95% CI)b | p c | OR (95% CI)b | p c | |
| Previous OSA | 1.48 (1.46, 1.50) | <.0001 | 1.39 (1.37, 1.41) | <.0001 |
| Current hypertension | 1.33 (1.31, 1.34) | <.0001 | 1.35 (1.33, 1.36) | <.0001 |
| Extended length of stay | 1.09 (1.07, 1.11) | <.0001 | 1.10 (1.08, 1.12) | <.0001 |
| Any ICU-stay | 1.01 (1.00, 1.02) | .0185 | 1.06 (1.04, 1.07) | <.0001 |
| Any respiratory complications | 1.06 (1.02, 1.10) | .0015 | 1.08 (1.04, 1.12) | <.0001 |
CI = confidence interval; ICU = Intensive Care Unit; OR = Odds ratio; OSA = Obstructive Sleep Apnea sMVAP = Symptomless Multi-Variable Apnea Prediction. Any ICU-stay defined as Any Stay in Intensive Care Unit. Any respiratory complications defined as diagnosis of Pulmonary Embolus, Acute Respiratory Distress Syndrome, and/or Aspiration Pneumonia. Extended length of stay defined as a length of stay >90th percentile for given procedure code. Model adjusted for surgical category and hospital.
aConditional logistic regression model controlled for effects of Surgical Category and Hospital (see Table 1).
bEstimates presented as OR and 95% CI, associated with a 0.1 unit increase in sMVAP.
c p-value from logistic regression model.
