The use of a reliable, ubiquitous, inexpensive, and user-friendly tablet-based system to track target lesion improvements in subjects with plaque psoriasis treated with clobetasol propionate 0.05% spray.

Abstract Ubiquitous electronic devices, such as smartphones and tablets, have the potential to enable a fundamental shift in the paradigm of healthcare as these devices may allow patients and health care providers (HCPs) to rapidly and remotely communicate with each other. Once fully realized, these devices may facilitate interactions between patients and HCPs. While these devices hold much promise, much work remains in assessing their viability in various diseases. A pilot study was conducted to investigate the use of a tablet-based numeric rating scale to assess improvements in a plaque psoriasis target lesion treated with clobetasol propionate 0.05% spray (CPS). Twenty-eight subjects with plaque psoriasis enrolled and were treated with CPS twice daily for 15 days. Target lesion severity (scale of 0 [no psoriasis] to 10 [very severe psoriasis]) and effectiveness scores (scale of 0 [none] to 3 [severe]) were recorded using a tablet-based system by the investigator and subjects. The tablet was also used to take photos of the target lesion to capture photographic evidence of improvement. Investigator and subject assessed target lesion severity and effectiveness scores improved during the study from baseline to day 15; in addition subjects indicated a high level of satisfaction with CPS treatment. Very few technological failures were reported and captured photographs were consistent visit to visit and of high quality. Taken together, this study supports the use of a tablet-based system to measure and track plaque psoriasis disease progression and also confirmed that CPS is an effective and safe treatment for plaque psoriasis.
