Patient–physician perception gaps in setting treatment goals and communication including shared decision making: Results from the survey illuminating dialogues and insights in onychomycosis management (IDIOM survey)

Onychomycosis, an infectious disease affecting the nails, can spread within oneself and to others, potentially leading to functional disabilities, therefore achieving a complete cure is necessary. Additionally, shared decision making (SDM) has been gaining attention in the treatment of various diseases in recent years. This study aimed to uncover the realities of patient–physician communication and perception in onychomycosis treatment, particularly in setting treatment goals and the SDM process for selecting therapeutic agents. We conducted a web-based survey of both patients and dermatologists to identify issues in the decision-making process for onychomycosis treatment. The survey revealed several communication challenges between patients and dermatologists regarding onychomycosis treatment. First, a notable percentage of dermatologists do not prioritize a complete cure for onychomycosis in their treatment goals. Second, the dermatologists' treatment explanations tended to emphasize risks, information necessary for appropriate decision-making was not adequately conveyed to patients, and SDM practice was insufficient (the mean scores of SDM-Q-9 and SDM-Q-Doc were 49.0 and 70.9, respectively). Third, dermatologists overestimated the reluctance of older patients to take oral medications. Dermatologists should recognize their patients' expectations for a complete cure for onychomycosis and choose a therapeutic agent that meets patients' needs. Furthermore, dermatologists should explain the benefits and risks of treatment options in a balanced manner, strive for improved patient–physician communication, and aim for a complete cure by administering suitable treatment.
