Understanding Sleep in Hospitalized Older Patients
The overall goal of this research is to elucidate how environmental, healthcare, and patient-level factors and patients' level of perceived control impact sleep duration and quality in hospitalized older patients and to assess whether better in-hospital sleep is associated with improved physical activity and health outcomes.
We hypothesize that environment, healthcare disruptions and patient symptoms will be significantly associated with objective and subjective sleep duration and sleep quality in hospitalized older patients.
We also hypothesize that a high level of perceived control will be associated with improved sleep duration and quality in hospitalized older patients.
We further hypothesize that shorter sleep duration and quality in hospitalized older adults will be associated with adverse health outcomes, namely higher blood pressure and blood sugar.

- Sleep will be measured using subjective reports (Karolinska Sleep Diary on Daily Sleep Assessment). [ Time Frame: January 2010-January 2015 ] [ Designated as safety issue: No ]
- Sleep will also be measured objectively using actigraphy. [ Time Frame: January 2010-January 2015 ] [ Designated as safety issue: No ]

Inpatient Elders Age 50 and up
The study population is community-dwelling ambulatory patients age 50 or above hospitalized on the University of Chicago general medicine service. Exclusion criteria include: (1) transfer from the ICU or another hospital; (2) cognitively impaired; (3) not ambulatory; (4) residents of a nursing home or skilled nursing facility; (5) on bedrest; (6)documented sleep disorder in their medical history (i.e. obstructive sleep apnea, narcolepsy, etc).
This research can lead to a better understanding of the effects of inpatient sleep on health outcomes for hospitalized older patients and can help inform the design and evaluation of interventions designed to improve sleep in hospitalized older patients. This work can also form the foundation for understanding the longer term health effects of inpatient sleep loss for older patients that are potentially modifiable.
