The clinical effectiveness of preoperative screening and post-screening interventions for obstructive sleep apnea: A systematic review and meta-analysis
Bibliographic record
Abstract
OBJECTIVES: The objective of this systematic review and meta-analysis is to evaluate the clinical utility of preoperative screening for obstructive sleep apnea (OSA) and determine the impact of targeted interventions on reducing postoperative adverse outcomes in surgical patients identified as high risk of OSA (HR-OSA). METHODS: A comprehensive literature search was conducted across multiple databases for studies evaluating the utilization of validated OSA screening tools and OSA interventions within the surgical setting. Primary outcomes included postoperative adverse respiratory and cardiac events, delirium, length of stay (LOS), intensive care unit (ICU) admissions, 30-day readmissions, and mortality. Interventions included continuous positive airway pressure (CPAP) or auto-titration positive airway pressure (APAP) use, sleep consultation, OSA safety protocols, wrist bands, and patient education. Certain studies used a combination of these interventions for HR-OSA patients. RESULTS: Fifty-four studies (324,935 patients) were included. The odds of adverse postoperative respiratory complications (OR 3.59, 95 % CI: 1.73-7.43) and cardiac complications (OR 2.82, 95 % CI: 1.62-4.92) events were significantly higher, and hospital LOS was significantly longer (mean difference: 0.79 days, 95 % CI: 0.42-1.15) for HR-OSA patients than those at low risk of OSA (LR-OSA). The odds of delirium, ICU admission, and 30-day readmission were not significantly increased for HR-OSA patients. In contrast, for HR-OSA patients who received post-screening interventions such as safety protocols, education and other targeted interventions, no significant differences in respiratory complications (OR 0.86, 95 % CI: 0.56-1.31), delirium (OR 0.69, 95 % CI: 0.12-4.06), escalation of care (OR 0.86, 95 % CI: 0.62-1.18), or composite adverse events (OR 0.81, 95 % CI: 0.61-1.08) were found compared to OSA patients who received no intervention. CONCLUSIONS: Our findings confirm HR-OSA as a risk factor for postoperative adverse events. Preoperative screening for OSA and subsequent targeted perioperative interventions and management strategies may contribute to a reduction in postoperative adverse outcomes. The current evidence regarding the efficacy of targeted interventions is limited by significant heterogeneity and sparsity of high-quality data and should be interpreted as exploratory.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
