Quality of life in nonorganic and organic sleep disorders: I. Comparison with normative data.
Subjective health-related quality of life (HRQoL) was investigated in 100 patients with disturbed sleep (39 women aged 52 +/- 13 years and 61 men aged 53 +/- 10 years) referred to the sleep laboratory and compared with HRQoL in 100 normal healthy adults. Measurements included the Quality of Life Index (QLI) (Mezzich and Cohen), and objective (polysomnographic) and subjective (psychometric) quality of sleep and awakening. Statistical analysis (Mann-Whitney U-test) showed HRQoL to be significantly reduced in sleep disorders (SDs), with a more pronounced reduction in nonorganic than in organic SDs. Patients with nonorganic hypersomnia were more disturbed than those with nonorganic insomnia. Within organic SDs, patients with apnea were more disturbed than those with obstructive snoring. Out of ten elementary HRQoL components, seven were disturbed in SDs: physical well-being, psychological well-being, self-care and independent functioning, occupational functioning, interpersonal functioning, personal fulfillment, and overall quality of life. No differences between patients and normal healthy subjects where found in the components social support, community and services support or spiritual fulfillment. Patients suffering from nonorganic SDs had significantly worse scores in physical and psychological well-being and overall quality of life than those with organic SDs. Patients with both SDs and additional diagnoses of affective disorders had more profoundly reduced HRQoL than those with anxiety disorders. Follow-up of 51 patients (31 with nonorganic SDs and 20 with organic SDs) one year after sleep laboratory investigation and subsequent treatment found significantly improved HRQoL compared with pre-treatment. Moreover, patients diagnosed and treated in the sleep laboratory showed lower re-hospitalization rats.
