The Impact of Color Fidelity on Evaluation of Patients in the Outpatient Dermatologic Setting.

Abstract：

BACKGROUND AND OBJECTIVES:To demonstrate that high color fidelity light-emitting diode (LED) sources are preferred by dermatologists for the evaluation of patients during standard-of-care, outpatient visits when compared to low color fidelity LED sources similar to fluorescent lighting. STUDY DESIGN/MATERIALS AND METHODS:Three different LED sources were installed in exam rooms at a single, academic, medical institution (low color fidelity [82 color rendering index (CRI)] similar to fluorescent lighting, and high color fidelity [97 CRI and 96+red CRI]). A cross-sectional survey study was conducted in three parts. Naturalness (i.e. ability to reproduce natural, daylight conditions), effectiveness, color contrast, comfort, and overall performance of each LED source were rated on a 5-point scale from 0 to 4 with 0 being the worse, and 4 being the best. The first part included a survey of board-certified dermatologists (n = 3) assessing their visual experience while clinically evaluating a subset of patients during standard-of-care outpatient visits. The second survey was completed by dermatologic medical providers (n = 55) at three separate monthly departmental Grand Rounds sessions in which standardized patients were evaluated with the LED sources. Lastly, patients (n = 75) finished a survey assessing the comfort level of the LED sources. RESULTS:In the first part of the study, all dermatologists significantly preferred the high color fidelity sources over low color fidelity sources based on all five evaluation criteria, with two preferring the 97 CRI LED source overall, while the third dermatologist favored 96+red CRI. Assessments provided by the 55 participants at Grand Rounds demonstrated that the 97 CRI was most "liked." Patients also preferred the high color fidelity LED source, reporting the 96+red CRI source was the "most comfortable." CONCLUSION:Dermatologists, dermatologists-in-training and mid-level providers significantly prefer high color fidelity LED sources for outpatient evaluation of dermatologist patients in enclosed spaces, rating them the more natural, effective, comfortable, and providing superior color contrast than low color sources. Patients also favor high color fidelity LED sources as being the most comfortable in the clinic room. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.
