Smart Lighting for Nursing Home Residents With Dementia
NCT05825404 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05825404
The ClinicalTrials.gov registry entry for NCT05825404 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 51 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Penn State University, which has 233 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Alzheimer's Disease and Related Dementias appearing as the primary indexed condition, and to 2 interventions — of which Control is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05825404 reports 2 study locations spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
