Dose–response relationship of sleep apnea therapy and healthcare use in patients with comorbidities
Bibliographic record
Abstract
STUDY OBJECTIVES: Obstructive sleep apnea (OSA) has complex interactive relationships with several other conditions. Previous research suggests that consistent adherence to positive airway pressure (PAP) therapy can reduce healthcare resource utilization (HCRU) in comorbid populations. We hypothesized that PAP therapy use would be associated with dose-dependent improvements in HCRU among patients with OSA and comorbid chronic obstructive pulmonary disease (COPD), type 2 diabetes, depression, heart failure, or atrial fibrillation. METHODS: We analyzed a linked dataset of medical/pharmacy claims data and objective PAP usage data for adults with newly diagnosed OSA between January 2015 and May 2021. Comorbidities were defined by at least two healthcare encounters or at least one hospitalization with the relevant diagnosis in the year before PAP initiation (index). HCRU outcomes included all-cause hospitalizations and emergency room (ER) visits over 12 and 24 months post-index. RESULTS: Among 377 830 patients with OSA (mean age: 51.7 years; 57.7% male), 6.6% had COPD, 18.7% type 2 diabetes, 16.5% depression, 4.2% heart failure, and 5.2% atrial fibrillation. Across all comorbidity cohorts, PAP usage was associated with a dose-dependent reduction in HCRU over 12 and 24 months. Risk-adjusted analyses showed HCRU benefits beginning at 2 to less than 4 hours of average nightly PAP use. Each additional hour of use was associated with a 4.1%-6.2% reduction in hospitalizations and ER visits (all analyses p < .0001). CONCLUSIONS: PAP therapy use is associated with dose-dependent reductions in HCRU among patients with OSA and major comorbidities. These findings may support data-driven reimbursement policies and highlight the value of treating OSA in complex patient populations.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
