UNASSIGNED: 107 Background: Insomnia is difficulty with sleep onset, maintenance, early morning wakening or non-restorative sleep. @entity5 prevalence is 30-75%. Daytime consequences include fatigue. It is under-reported and impairs quality of life. Measurement previously required sleep laboratories. Technology advances help real-time measurement in the natural environment. This study investigated the feasibility and acceptability of a wireless device to evaluate sleep in @entity5 . METHODS: Prospective observational study: Stage A: 10 consecutive in- @entity1 hospice admissions; Stage B: 20 consecutive community @entity1 Sleep quality was rated by Insomnia Severity Index (ISI). @entity1 used a wireless non-contact bedside monitor (SleepMinder) for 3 nights. Acceptability questionnaires were completed by @entity1 and nurse (Stage A) or family (Stage B).Descriptive statistics were generated by Microsoft Excel. RESULTS: 30 @entity1 with @entity5 were recruited. Median age: 63 years (47-84). Median Eastern Cooperative Oncology Group (ECOG) performance score: 2 (0-3). In- @entity1 (n=10): In 50%, sleep onset was delayed >30 minutes. Median duration: 8 hours. Median awakenings per night: 1 (0-8). Median @entity25 (proportion of time in bed spent asleep): 89% (74-100%). ISI score correlated with sleep duration in 70%. @entity1 and nurses reported 100% device acceptability. Community (n=20): Sleep onset was delayed >30 minutes in 25%. Median duration: 8 hours. Median awakenings per night: 3 (0-10). Median @entity25 : 91% (46-100). ISI score correlated with sleep duration in 90%. @entity1 and family reported 100% device acceptability. CONCLUSIONS: (1)A wireless monitor effectively measures sleep in @entity5 in both inpatient and community settings, (2) High acceptability supports clinical use, (3) Subjective sleep quality reports correlate with device, and (4) Further research: evaluate sleep improvement interventions with device.
