RESUMEN
Background: The Centers for Disease Control and Prevention (CDC) reported that between 28.5% and 44.1% of adults in the US sleep less than seven hours nightly. Aims: The aim of this quality improvement project was to improve sleep quality and duration among patients aged 40 and older with insomnia disorder in an outpatient mental health clinic. Methods: Patients diagnosed with insomnia disorder who were sleeping less than seven hours at least three nights weekly participated in the project (n = 20). Sleep hygiene education was provided and participants kept a sleep diary. The duration and quality of sleep was evaluated by comparing the information recorded in the diaries with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition description of insomnia disorder. Results: All participants achieved improvement to 6-8 hours of restful sleep nightly.
