OBJECTIVE: Phototherapy is a convenient and effective treatment alternative for a range of skin diseases. However, a major challenge in patient adherence to phototherapy may be the necessity of visiting a phototherapy center regularly over an extended period of time. The aims of this study were (i) to investigate the adherence rate to phototherapy and (ii) to determine factors associated with adherence to narrow-band ultraviolet B phototherapy (nbUVB) treatment.

PATIENTS AND METHODS: A retrospective review of patient records who underwent nbUVB phototherapy between January 1, 2018, and March 31, 2023, was performed. Patient records were reviewed for age, gender, skin type, diagnosis, type of phototherapy applied, duration of treatment, total number of sessions, presence of side effects, reasons for discontinuation of treatment, and perceived benefits of treatment.

RESULTS: Of a total of 729 patients undergoing phototherapy, 281 (38.5%) discontinued treatment before completing 20 sessions. In particular, younger patients and those who experienced fewer side effects tended to discontinue treatment prematurely. The most common reason for discontinuing treatment was difficulty in visiting the hospital regularly.

CONCLUSIONS: The patient’s compliance with phototherapy was 61.5%. These results indicate that phototherapy is still one of the preferred treatment methods, although many new treatment agents have been developed in dermatology in recent years. Identifying and addressing factors that affect patient adherence will certainly help increase the effectiveness of treatment.
