Using a novel scoring system for paronychia related to oncologic treatments (SPOT) for assessing paronychia severity and its correlation with pain index and quality of life.

BACKGROUND: Oncologic treatments may lead to the development of paronychia, which may cause severe pain and disability. However, a detailed objective scoring system is lacking.

OBJECTIVE: To develop an objective scoring system to quantify the severity of paronychia and also examine the correlation of this score with a pain index and patients' quality of life.

METHODS: A novel scoring system for paronychia related to oncologic treatments (SPOT), consisting of four parameters, namely redness, oedema, discharge and granulation tissue, was designed to assess the severity of paronychia. The visual analogue scale (VAS) and Dermatology Quality of Life Index (DLQI) were recorded, and their association with the SPOT scores was analysed.

RESULTS: Ninety patients were enrolled from three medical centres in Taiwan. Severity of paronychia was determined by the scores of SPOT. Patients in the severe group had higher DLQI scores (severe vs. mild: P = 0.0018; severe vs. moderate: P = 0.0015). Both the DLQI and pain index scores were significantly higher in patients with higher dominant hand SPOT scores.

CONCLUSIONS: The SPOT scores demonstrated the association of the paronychia severity with DLQI and pain. It may thus be useful in clinical practice and future studies.
