Patient-Controlled Ambient Light to Reduce Pre-Visit Anxiety in Dermatology Patients
Sponsor: Stanford University
Summary
Many patients feel anxious while waiting to see a dermatologist, especially in clinics that diagnose and treat skin cancer. The purpose of this study was to learn whether spending 10 minutes before the visit in an exam room lit by a tabletop colored-light device, which patients control themselves, lowers anxiety compared with usual room lighting. Adult patients at one Stanford dermatology clinic were assigned by clinic week: during intervention weeks the device was on and patients could choose its color and brightness with a handheld remote; during control weeks the room had standard lighting. Patients answered short questionnaires about how they felt when they arrived and again after 10 minutes in the room.

Interventions
Patient-controlled ambient light (Serene Sphere)
Tabletop ambient light with a frosted diffusing dome that fills the examination room with soft colored light at standard indoor brightness. A handheld remote lets the participant choose among preset color themes and adjust brightness. Research staff switched it on and briefly demonstrated the remote; the participant then spent 10 minutes alone in the room before any provider encounter. The device does not touch the participant or collect any data.
