Item Impact of Ambient Bright Light on Agitation in Dementia(2010) Barrick, Ann Louise; Sloane, Philip D.; Williams, Christianna S.; Mitchell, C. Madeline; Connell, Bettye Rose; Wood, Wendy; Hickman, Susan E.; Preisser, John S.; Zimmerman, SherylObjective To evaluate the effect of ambient bright light therapy on agitation among institutionalized persons with dementia. Methods High intensity, low glare ambient lighting was installed in activity and dining areas of a state psychiatric hospital unit in North Carolina and a dementia-specific residential care facility in Oregon. The study employed a cluster-unit crossover design involving four ambient lighting conditions: AM bright light, PM bright light, All Day bright light, and Standard light. Sixty-six older persons with dementia participated. Outcome measures included direct observation by research personnel and completion by staff caregivers of the 14-item, short form of the Cohen-Mansfield Agitation Inventory (CMAI). Results Analyses of observational data revealed that for participants with mild/moderate dementia, agitation was higher under AM light (p=0.003), PM light (p<0.001), and All Day light (p=0.001) than Standard light. There also was a trend toward severely demented participants being more agitated during AM light than Standard light (p=0.053). Analysis of CMAI data identified differing responses by site: the North Carolina site significantly increased agitation under AM light (p=0.002) and PM light (p=0.013) compared with All Day light while in Oregon, agitation was higher for All Day light compared to AM light (p=0.030). In no comparison was agitation significantly lower under any therapeutic condition, in comparison to Standard lighting. Conclusions Ambient bright light is not effective in reducing agitation in dementia and may exacerbate this behavioral symptom.Item Pragmatic Trials in Long-Term Care: Research Challenges and Potential Solutions in Relation to Key Areas of Care(Elsevier, 2022-08) Resnick, Barbara; Zimmerman, Sheryl; Gaugler, Joseph; Ouslander, Joseph; Abrahamson, Kathleen; Brandt, Nicole; Colón-Emeric, Cathleen; Galik, Elizabeth; Gravenstein, Stefan; Mody, Lona; Sloane, Philip D.; Unroe, Kathleen; Verbeek, Hilde; Medicine, School of MedicineAs a method of research, pragmatic trials are recommended so as to generate results that are applicable to real-world care. This intent is especially important for the millions of older adults who receive long-term care in thousands of nursing homes and assisted living communities across the country-and many millions more around the globe. This article presents key points raised by experts participating in a conference funded by the National Institute of Aging held at the 2021 conference of the Society for Post-Acute and Long-term Care Medicine. The purpose of the conference was to convene leading clinicians, researchers, and industry partners to address special considerations of pragmatic trials in long-term care. Cross-cutting and unique challenges and solutions to conducting pragmatic trials were discussed focusing on 3 areas of clinical relevance to long-term care: (1) functional care and outcomes, (2) psychosocial care and quality of life, and (3) medical care and outcomes, with a special focus on persons with dementia. Challenges and innovative solutions were organized across the 9 domains of the revised Pragmatic-Explanatory Continuum Indicator Summary (PRECIS) Tool, and future research recommendations for pragmatic trials in long-term care were identified.
