The Epworth Sleepiness Scale (ESS) has previously been used to assess patients with insomnia (Johns M, 1997), however, patients with idiopathic insomnia often suffer from states of hypervigilance, displaying normal ESS scores (Reidel BW, 2000).
For these patients, plotting the ESS and SleepMed Index (SMI) scores on the Sleep Matrix may enable clinicians to quickly identify the problem and consider therapeutic options for managing their condition.
Excessive sleepiness is generally not a feature of primary insomnia and when present, frequently suggests the presence of other sleep disorders (Sateia MJ, 2000).
Patients with ESS scores of greater than 10 need clinical correlation as to the presence of other underlying sleep disorders.
The SMI and the Sleep Matrix may help physicians determine when another underlying sleep disorder may be present, signalling the need for a formal sleep study.
Specifically, patients with ESS/SMI scores falling in the upper half of the Sleep Matrix may require referral to a sleep specialist for further evaluation, especially if initial treatment does not result in improvement.
The use of the Sleep Matrix indicates significant differences between patients treated for insomnia and estimates of their prior untreated condition. Thus, the Sleep Matrix may also be a useful indicator of treatment response (Morin CM, 2002).
