Smart Lighting for Nursing Home Residents With Dementia
Completed · Not applicable
Conditions studied: Alzheimer's Disease and Related Dementias
In brief
This proposed study seeks to develop a smart ambient bright light (SABL) intervention to provide auto-controlled, consistent indoor lighting that incorporates natural daylight. This SABL includes tunable LED lights, photosensors, and controllers. The SABL system has a pre-programmed 24-hour control schedule for illuminance settings to mimic the natural bright-dark cycle. It will automatically adjust the lights to accommodate the daylight effect to minimize staff burden and maximize the LI effect. The SABL will be installed in participants' bedrooms and designated areas in the dining rooms and activity rooms for four weeks. Each participant will wear a personal light monitor to measure the lighting dosage each participant receives. This study will address three aims: 1) pilot test the effect of SABL on reducing agitation in persons with ADRD, 2) evaluate the fidelity of the SABL delivery, and 3) evaluate the feasibility of implementing the SABL. The study will be conducted in two NHs in Pennsylvania. For aims 1 and 2, the investigators will use a crossover, cluster randomized control trial (RCT) and will enroll residents with ADRD and agitation. For aim 3, the investigators will use a mixed methods design and will interview NH stakeholders to evaluate the acceptability, feasibility, and appropriateness of the intervention. This is the first study that incorporates daylight in ambient light interventions and the first study that addresses the measurement, feasibility, and fidelity of lighting interventions. Findings will establish evidence-based implementation strategies and the best design for SABL to reduce agitation for persons with ADRD in NHs.
