Self-applied, unattended PSG in the home environment using Somte PSG V2 (Somte) has not been validated in pregnant women in early to mid-gestation. We undertook a study to evaluate the accuracy of Somte compared to attended PSG. The agreement between apnoea hypopnea index (AHI) and respiratory disturbance index (RDI) scores in Somte and PSG in early to mid-gestation were assessed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Pregnant women (\u2264\u200924\u00a0weeks gestation) were scheduled for PSG and Somte within a 7-day window, in any order. Somte were self-applied and completed in the home. Somte were scored blinded to PSG result. AHI was the primary outcome of interest, though an AHI\u2009\u2265\u20095 or RDI\u2009\u2265\u20095 on PSG was considered diagnostic of Obstructive Sleep Apnoea (OSA). AHI, RDI, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) was calculated and receiver operating characteristic (ROC) curves were produced. Bland\u2013Altman plots were used to determine agreement.

PSG were completed at around 14.1\u00a0weeks\u2019 gestation (IQR 13.4, 15.7). The time interval between Somte and PSG was a median of 4\u00a0days (IQR 2, 7 (range 1\u201312)). Five (20.8%) women had OSA on PSG at AHI\u2009\u2265\u20095 and 10 (41.6%) women had OSA on PSG at RDI\u2009\u2265\u20095. Somte and PSG did not differ in the measurement of AHI ((1.8, 1.6, <jats:italic>p<\/jats:italic>\u2009=\u20090.09) or RDI (3.3, 3.5), <jats:italic>p<\/jats:italic>\u2009=\u20090.73).<\/jats:p>\n                <jats:p>At AHI\u2009\u2265\u20095, diagnostic test accuracy (area under the ROC curve) of Somte was 0.94, sensitivity 80.0%, specificity 94.7%, PPV and NPV were 80.0% and 94.7% respectively. At RDI\u2009\u2265\u20095, diagnostic test accuracy (area under the ROC curve) was 0.95, sensitivity 60.0%, specificity 93.0% and PPV and NPV were 85.7% and 76.4% respectively.
