The minimum period of polysomnography required to confirm a diagnosis of severe obstructive sleep apnoea
Abstract
Background and objective: To combine the diagnosis of OSA with titration of positive airway pressure (PAP), current guidelines recommend that split‐night polysomnography (PSG) be performed if an AHI of ≥40/h is recorded over 2 h. However, the diagnostic validity of partial‐night PSG is uncertain. This study aimed to test the validity of partial‐night PSG and to determine the optimum AHI cut‐off points. Methods: Patients who visited the sleep centre at a tertiary medical centre between January and December 2008, for symptoms related to sleep disorders (sleepiness, snoring, sleep disturbance), and who completed full‐night PSG, were evaluated for this study. Full‐night PSG data were processed to obtain partial‐night PSG data, from which AHI were computed as a reference for diagnosing severe OSA. Full‐night and partial‐night PSG data obtained over different recording times (expressed as x‐h PSG, where x = 1–6) were compared using receiver operating characteristic (ROC) curve analysis. The diagnostic validity of 2‐h PSG with different AHI cut‐off points (25/h to 45/h) was also calculated. Results: Data from 198 PSG recordings was processed. For 2‐h PSG, an AHI cut‐off point of 30/h gave the highest accuracy of 90.9%. Comparing areas under the ROC curves (AUC), 2‐h PSG (AUC = 0.97) was as good as 2.5‐h PSG (AUC = 0.977, P = 0.057) and 3‐h PSG (AUC = 0.978, P = 0.125), but was better than 1.5‐h PSG (AUC = 0.955, P = 0.016). Conclusions: Partial‐night PSG is effective for diagnosing severe OSA. If there is an unabridged PSG recording indicating an AHI of ≥30/h for 2 h, severe OSA can be diagnosed and PAP titration initiated.

Four studies that examined diagnostic accuracy and performance characteristics of a split-night protocol used the initial truncated PSG to serve as a representative surrogate of the initial diagnostic portion of a split-night study; the first 2-3 hours of the recording were compared to the full night of sleep recording.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
