Sleep-disordered breathing during pregnancy has long occupied a clinical blind spot — undertreated partly because guidance on how to act on it simply didn't exist. For the first time, the American College of Chest Physicians has issued a formal, evidence-graded clinical practice guideline filling that void, with direct implications for maternal and fetal outcomes in the millions of pregnancies occurring annually in the United States.
The guideline, published in Chest, emerged from a systematic review of the MEDLINE and Cochrane Library databases, guided by structured PICO clinical questions across four domains: screening, diagnosis, treatment, and post-partum re-evaluation. The expert panel issued nine conditional recommendations. Among the most consequential: universal screening of pregnant patients for OSA is recommended, using either a pregnancy-specific questionnaire or a validated standard tool. For those flagged as at-risk, the panel considers home sleep testing (HST) an acceptable diagnostic alternative to in-laboratory polysomnography — a meaningful practical concession given the logistical barriers pregnant patients face with overnight clinic studies. Treatment recommendations, while graded as conditional rather than strong due to limited high-quality randomized evidence, align with CPAP-based approaches.
The conditional — rather than strong — grading of all nine recommendations honestly signals the field's evidential limitations. OSA in pregnancy remains chronically understudied in rigorous randomized trials; most available data are observational, with heterogeneous cohorts and variable outcome definitions. The guideline's value is therefore partly cartographic: it maps what is known, where evidence is thin, and where clinical consensus must carry weight. Importantly, the acceptance of home sleep testing reflects a pragmatic approach to a population with heightened adherence barriers. Clinicians and researchers should treat this guideline not as a settled framework but as a structured baseline from which future prospective trials — particularly on CPAP adherence and neonatal outcomes — can build. For health-conscious adults planning pregnancy, the existence of this guidance represents a meaningful step toward routine OSA consideration in prenatal care.
