Health Health Sciences Nursing pain medical inpatients circadian entrainment light sleep-wake For many patients, the hospital environment may contribute to discomfort by providing a lighting structure that interferes with circadian rhythmicity, sleep, mood, and pain. Using Nightingale’s Environmental Theory and the Heitkemper/Shaver Human Response Model, this study described light exposure, sleep-wake patterns, mood, and pain in 40 adult medical inpatients. Over 72 hours, light exposure and sleep-wake patterns were continuously measured with wrist actigraph/light meters, mood was measured using the POMS Brief Form, and pain scores were obtained from participants’ medical records. The convenience sample included 23 females and 17 males, mean age 50 years. Light exposure levels were low during the daytime (M = 104.8, SD = 131.13) and nighttime (M = 7.07, SD = 7.00). Sleep time (minutes) was also low during daytime 161.02 (M = 161.02, SD = 81.40) and nighttime (M = 236.35, SD = 72.27). Participants experienced significant pain on a 0-10 scale (M = 5.91, SD = 1.55). POMS total mood disturbance score was also high (M = 19.56, SD = 13.11). Fragmented sleep and low intra-daily stability (IS) scores showed restless sleep and little circadian synchronization with the low levels of hospital lighting (the external zeitgeber). The mood subscale of fatigue significantly predicted pain; light exposure significantly predicted fatigue. This study provides preliminary data, useful in developing and testing future lighting interventions to improve sleep-wake patterns and consequently, mood and pain in hospitalized adults. 2012-08-24 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1341350232 http://rave.ohiolink.edu/etdc/view?acc_num=case1341350232 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
