Patient-reported outcomes in lasers and light therapy.

As the prevalence of lasers and light devices to treat dermatologic conditions increases, patient reported outcomes (PROs) will be an essential component of evaluating clinical efficacy and patient satisfaction. PROs may be used to identify patients' values, weigh risks and benefits of various therapies, identify barriers to treatment and help guide the development of new therapies. Utilizing patient and physician assessments may help determine if a new treatment is objectively better than currently available therapies. In creating a patient-centered treatment plan using laser and light modalities, it is critical to evaluate side effects using PROs. Determining and resolving barriers to treatment has benefits at the individual level and the population level. Many PRO measures (PROMs) are available to use for general and specific dermatologic conditions. The Dermatologic Life Quality Index, Skindex, and FACE-Q are PROMs that have been used in laser and light therapy studies. Selecting the proper instrument should be based on study aims to yield high quality data. Herein, we assess PROs use in laser and light treatment protocols to improve patient care, increase patient satisfaction and reduce barriers to care, and review dermatology PRO measures (PROMs) used in published laser and light clinical studies.
