  1. Use of home sleep studies for diagnosis of the sleep apnoea/hypopnoea syndrome.

    Article - En anglais

    Background

    A study was undertaken to test the hypothesis that unsupervised domiciliary limited sleep studies do not impair the accuracy of diagnosis when used to investigate the sleep apnoea/hypopnoea syndrome (SAHS) and can be cheaper than laboratory polysomnography.

    Methods

    For validation, 23 subjects with suspected SAHS underwent laboratory polysomnography and a home study (EdenTec 3711) on successive nights.

    All subjects with>15 apnoeas+hypopnoeas (A+H)/hour on polysomnography showed>30 A+H/hour on their home study.

    Thereafter, in a prospective trial 150 subjects had a home study as the initial investigation and studies showing>30 events/hour were regarded as diagnostic of SAHS.

    Those showing fewer events were investigated with polysomnography if necessary.

    Time to treatment, outcome, and costs of this protocol were compared with those of 75 patients investigated initially with polysomnography.

    Results

    Of the prospective trial subjects, 29% had>30 A+Hlhour and proceeded directly from home study to treatment ; 15% without daytime sleepiness were not investigated further.

    Polysomnography was undertaken to establish a diagnosis in 56% of cases, including 18% whose home studies were unsuccessful.

    Compared with the 75 control patients, this protocol gave a diagnosis faster (median 18 (range 0-221) versus 47 (0-227) days, p<0.001) and more cheaply (mean (SD) £164 (104) versus £210 (0), p<0.001). (...)
