Answer

Because PSG is expensive and not widely available, there has been extensive interest in alternative diagnostic approaches, such as clinical prediction rules and portable monitors. A limited number of questionnaires are available to detect some sleep disorders, but those instruments do not achieve the reliability of PSG, which remains the recommended method of assessing patients with suspected sleep disorders. The role of those questionnaires is mainly to serve as a screening tool for identifying patients at risk for OSAS. [47, 48, 49, 50]

Many questionnaires have been developed for screening OSAS. The Rome Questionnaire (RQ) is a seven-item questionnaire useful in identifying adult patients at risk for OSAS. The RQ, together with the body mass index (BMI), is reported to be a useful tool for selecting patients at higher risk for moderate-to-severe OSAS, who need a prompt PSG evaluation. [51]
