Insomnia poses significant challenges to public health. It is a common condition associated with marked impairment in function and quality of life, psychiatric and physical morbidity, and accidents. As such, it is important that effective treatment is provided in clinical practice. To this end, this paper reviews critical aspects of the assessment of insomnia and the available treatment options. These options include both non-medication treatments, most notably cognitive behavioral therapy for insomnia, and a variety of pharmacologic therapies such as benzodiazepines, "z-drugs", melatonin receptor agonists, selective histamine H1 antagonists, orexin antagonists, antidepressants, antipsychotics, anticonvulsants, and non-selective antihistamines. A review of the available research indicates that rigorous double-blind, randomized, controlled trials are lacking for some of the most commonly administered insomnia therapies. However, there are an array of interventions which have been demonstrated to have therapeutic effects in insomnia in trials with the above features, and whose risk/benefit profiles have been well characterized. These interventions can form the basis for systematic, evidence-based treatment of insomnia in clinical practice. We review this evidence base and highlight areas where more studies are needed, with the aim of providing a resource for improving the clinical management of the many patients with insomnia.

BACKGROUND:Comprehensive discharge education can improve patient understanding and may reduce unnecessary rehospitalization.OBJECTIVES:To understand nurse and physician communication practices around patient discharge education.SETTING:University of California, San Francisco Medical Center (UCSFMC).PARTICIPANTS:Nurses, interns, and hospitalists caring for hospitalized medicine patients.MEASUREMENTS:Participants were surveyed regarding discharge education practices. The survey asked respondents about 13 elements of discharge education found in the literature. For each element, participants were queried regarding: 1) the provider responsible for this element of patient education; 2) the frequency with which they communicate this teaching to patients; 3) how often they directly communicate with the nurse or physician caring for the patient about each element; and 4) tools to improve nurse–physician communication.RESULTS:A total of 129/184 (70%) nurses, interns, and hospitalists responded to the survey. The majority of respondents in all 3 groups felt that 9 of 13 elements were a combined responsibility. Nurses reported educating patients on these 9 items significantly more often than physicians (P < 0.05). All groups also agreed that instruction on 2 of the elements, summary of hospital findings and pending results, should be primarily the physicians' responsibility; these were the elements least often discussed by any provider. Despite the majority of items being agreed upon as a shared responsibility, communication between nurses and physicians regarding discharge education was low. Standardized verbal communication on the day of discharge was supported most strongly by all providers.CONCLUSIONS:Ambiguous responsibility for providing discharge education and poor communication between nurses and physicians offers an opportunity for improvement.

Timing and duration of sleep are controlled by the circadian system, which keeps an~24-h internal rhythm that entrains to environmental stimuli, and the sleep homeostat, which rises as a function of time awake. There is a normal distribution across the population in how the circadian system aligns with typical day and night resulting in varying circadian preferences called chronotypes. A portion of the variation in the population is controlled by genetics as shown by the single-gene mutations that confer extreme early or late chronotypes. Similarly, there is a normal distribution across the population in sleep duration. Genetic variations have been identified that lead to a short sleep phenotype in which individuals sleep only 4-6.5 h nightly. Negative health consequences have been identified when individuals do not sleep at their ideal circadian timing or are sleep deprived relative to intrinsic sleep need. Whether familial natural short sleepers are at risk of the health consequences associated with a short sleep duration based on population data is not known. More work needs to be done to better assess for an individual's chronotype and degree of sleep deprivation to answer these questions.
