Abstract

PURPOSE: The gold standard for diagnosis of OSAS is the sleep laboratory polysomnography (lab-PSG), which is technically demanding, labor-intensive, and time-consuming. Thus, screening of large undiagnosed population for OSAS may be cost efficient only by means of ambulatory devices suitable for home recording. The aim of our study was to validate the role of a home sleep study (HSS) in the diagnosis of OSAS.

METHODS: One hundred thirty six consecutive adults referred for PSG at the sleep disorders center. The sleep studies were carried out in the laboratory and at home on two different nights and with a maximum interval of 48 h. The HSS was designed to record nasal and oral flow, snoring, blood oxygen saturation and heart rate. Sensitivity, specificity and positive and negative predictive values at AHI cut-off values of 5 and 15 events/hour were calculated.

RESULTS: There was a strong correlation between apnea-hypopnea syndrome (AHI) from the HSS and PSG recordings (p< 0.001, r=0.73). Compared to lab-PSG for detecting AHI>5, the HSS demonstrated the sensitivity of 91,6%, the specificity of 33,3%, positive predictive value of 91,6%, negative predictive value of 33,3% and diagnostic value (accuracy) of 85%. Compared to lab-PSG for detecting AHI>15, the HSS demonstrated the sensitivity of 67%, the specificity of 84%, positive predictive value of 87,7%, negative predictive value of 60% and diagnostic value (accuracy) of 73,3%.

CONCLUSION: These data suggest that the HSS is accurate in confirming the diagnosis of OSAS where there is a suspicion of the disorder.

CLINICAL IMPLICATIONS: Yes.
