There is little information on diagnostic rates or treatment correlates of insomnia in real-world practice. Study objectives were to identify the 1-year prevalence, psychotropic pharmacotherapy and clinical correlates of diagnosed insomnia, nationally in the Veterans Health Administration (VHA). ⋯ The diagnosis of insomnia is associated with the filling of more psychotropic prescriptions, net of the presence of psychiatric co-morbidity in national VHA administrative data, and the prevalence of diagnosed insomnia is lower than that found in systematic surveys of the general population, a potential impediment to optimal treatment.

The aim of this study was to characterize health-care utilization, costs, and productivity in a large population of patients diagnosed with narcolepsy in the United States. ⋯ Narcolepsy was found to be associated with substantial personal and economic burdens, as indicated by significantly higher rates of health-care utilization and medical costs in this large US group of narcolepsy patients.

The Pittsburgh Sleep Quality Index (PSQI) is used extensively to assess subjective sleep disturbance in cancer populations. Although previous studies on the PSQI suggested a better fit for a two- or three-factor model than the original one-factor model, none accounted for the indicator-specific effect between sleep duration and habitual sleep efficiency. This study evaluated the PSQI's dimensionality and its convergent validity with cancer-related psychopathological states in female breast cancer patients. ⋯ The results support the PSQI's original unidimensional structure, demonstrating that the PSQI global score is a valid and parsimonious measure for assessing and screening sleep dysfunction in cancer patients.
