Sleep Disturbances and Risk of Hospitalization and Inpatient Days Among Older Women.

ABSTRACT: Determine the associations of sleep disturbances with hospitalization risk among older women.One thousand eight hundred and twenty-seven women (mean age 83.6 years) participating in Study of Osteoporotic Fractures Year 16 (Y16) examination (2002-2004) linked with Medicare and/or HMO claims. At Y16 examination, sleep/wake parameters were measured by actigraphy (total sleep time [TST], sleep efficiency [SE], sleep latency [SL], and wake after sleep onset [WASO]) and subjective sleep measures (sleep quality [Pittsburgh Sleep Quality Index] and daytime sleepiness [Epworth Sleepiness Scale]) were assessed by questionnaire. Measures except TST were dichotomized based on clinical thresholds. Incident hospitalizations were determined from claims data.Nine hundred and seventy-six women (53%) had ?1 hospitalization in the 3 years after the Year 16 examination. Reduced SE (odds ratio [OR] = 2.39, 95% confidence interval [CI] 1.69-3.39), prolonged SL (OR = 1.41, 95% CI 1.11-1.78), greater WASO (OR = 1.57, 95% CI 1.28-1.93), shorter TST (OR = 1.98, 95% CI 1.42-2.77) and poorer sleep quality (OR = 1.33, 95% CI 1.07-1.65) were each associated with a higher age and site-adjusted odds of hospitalization; associations were attenuated after multivariable adjustment for traditional prognostic factors with the OR for reduced SE (OR = 1.60, 95% CI 1.08-2.38) and shorter TST (OR = 1.63, 95% CI 1.12-2.37) remaining significant. Among women who were hospitalized, greater WASO (rate ratio [RR] = 1.20, 95% CI 1.04-1.37) and poorer sleep quality (RR = 1.18, 95% CI 1.02-1.35) were each associated with a greater age and site-adjusted RR of inpatient days, but associations did not persist after multivariate adjustment.Older women with sleep disturbances have an increased risk of hospitalization partially attributable to demographics, poorer health status, and comorbidities.

Project description:ObjectiveTo test the hypothesis that non-frail older men with poorer sleep at baseline are at increased risk of frailty and death at follow-up.MethodsIn this prospective cohort study, subjective (questionnaires) and objective sleep parameters (actigraphy, in-home overnight polysomnography) were measured at baseline in 2505 non-frail men aged ≥67years. Repeat frailty status assessment performed an average of 3.4 years later; vital status assessed every four months. Sleep parameters expressed as dichotomized predictors using clinical cut-points. Status at follow-up exam classified as robust, intermediate (pre-frail) stage, frail, or died in interim.ResultsNone of the sleep disturbances were associated with the odds of being intermediate/frail/dead (vs. robust) at follow-up. Poor subjective sleep quality (multivariable odds ratio [MOR] 1.26, 95% CI 1.01-1.58), greater nighttime wakefulness (MOR 1.31, 95% CI 1.04-1.66), and greater nocturnal hypoxemia (MOR 1.47, 95% CI 1.02-2.10) were associated with a higher odds of frailty/death at follow-up (vs. robust/intermediate). Excessive daytime sleepiness (MOR 1.60, 95% CI 1.03-2.47), greater nighttime wakefulness (MOR 1.57, 95% CI 1.12-2.20), severe sleep apnea (MOR 1.74, 95% CI 1.04-2.89), and nocturnal hypoxemia (MOR 2.28, 95% CI 1.45-3.58) were associated with higher odds of death (vs. robust/intermediate/frail at follow-up). The association between poor sleep efficiency and mortality nearly reached significance (MOR 1.48, 95% CI 0.99-2.22). Short sleep duration and prolonged sleep latency were not associated with frailty/death or death at follow-up.ConclusionsAmong non-frail older men, poor subjective sleep quality, greater nighttime wakefulness, and greater nocturnal hypoxemia were independently associated with higher odds of frailty or death at follow-up, while excessive daytime sleepiness, greater nighttime wakefulness, severe sleep apnea and greater nocturnal hypoxemia were independently associated with an increased risk of mortality.

Project description:ObjectiveTo assess sleep quality of patients on a rehabilitation ward and to identify staff practices and beliefs about management of sleep disturbance.DesignMixed-methods design including patient surveys and staff interviews.SettingInpatient rehabilitation ward in a tertiary teaching hospital in Adelaide, Australia.ParticipantsOf the 345 screened inpatients who had been in a mixed post-acute rehabilitation ward for at least 5 days, 120 (43% women) were included. The mean age was 67.7 years and the main admission reason was functional decline (40%). Patients with stroke or traumatic brain injury were excluded. Eleven (n = 11) staff (a mix of doctors, nurses, and allied health) were interviewed.Main outcome measuresThe surveys comprised of the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, the Flinders Fatigue Scale, and the Sleep Inertia Questionnaire. The survey results were compared with functional outcomes using the functional independence measure (FIM). Staff interviews delved into barriers to good sleep, ward practices, and knowledge about sleep hygiene.Results43% of the surveyed patients reported having healthy amount of sleep. Sleep quality was not significantly correlated with rehabilitation outcomes (assessed using FIM). Staff reported having a good awareness of sleep hygiene; however, acknowledged limitations about the environment and routine which were not conducive to healthy sleep. They identified several actions which could be taken to improve patients' sleep hygiene.ConclusionsSleep disturbance is common for patients in rehabilitation. Rehabilitation wards should address this often-neglected critical component of rehabilitation to improve patient experience and potential participation in therapy. Introducing a systematic approach for assessing sleep during admission, establishing clear roles regarding sleep assessment and intervention among staff, and ensuring that patients and staff are aware of good sleep hygiene practices may promote better sleep during inpatient rehabilitation.
