SMI and Sleep Matrix
SleepMed Insomnia Index and Sleep Matrix
Purpose : Quantitative and differentiating measure of excessive sleepiness and sleep, pathology complaints
Admin time : 5-10 min.
User Friendly : High
Administered by : self or GP
Content : The SMI incorporates features extrapolated from the International Classification of Sleep Disorder (ICSD) criteria for the diagnosis of insomnia and other clinical features of primary and co-morbid insomnia. The questions were formulated to address important sleep factors, including sleep latency, performance anxiety, first night effect, the frequency of awakenings, sleep re-initiation, total sleep time, perceived sleep quality and impact on next day function.
The Sleep Matrix was developed to visually display the complexity of the sleep complaint in an effort to efficiently differentiate insomnia with differing etiologies from other sleep disorders and measure treatment outcomes. The Sleep Matrix plots the SMI scores on the x-axis against ESS scores on the y-axis. Six zones within the matrix help characterize the sleep complaint.

SMI and Sleep Matrix
Epworth Sleepiness Scale
Even in the presence of a decrease in total sleep time, patients with insomnia are not typically hypersomnolent. The current pathophysiology of insomnia is considered to be a hyperaroused state. Therefore, patients usually have normal ESS scores.
the SleepMed Insomnia Index (SMI), designed to quickly measure insomnia symptoms in a simple, standardized way. Similar to the ESS, the SMI is intended to be brief, enabling patients to quickly complete it. The SMI questionnaire provides a clinical measure of the characteristics and severity of the insomnia complaint.
In the clinical environment patients present with multiple sleep complaints that include primary insomnia, co-morbid insomnia, circadian rhythm misalignment, and other sleep disorders. Since the sleep complaint is often complex and associated with co-morbidities, a sleep vital sign using the SMI and ESS as a two dimensional matrix, the Sleep Matrix, offers a quantitative and differentiating measure of the sleep complaint. It is suggested that patients with abnormal insomnia scores with elevated ESS scores should be evaluated for other medical, psychiatric, or sleep disorder diagnoses as well as behavioral factors and pharmacologic influences.
