Assessment of "corticophobia" as an indicator of non-adherence to topical corticosteroids: A pilot study

Background: Concerns regarding topical corticosteroid (TCS) use, broadly known as corticophobia, are highly prevalent among dermatology patients and often result in non-adherence to TCS. This non-adherence contributes to poor disease control and increased health care costs. However, it is unknown if assessment of these concerns might help to identify patients at risk of TCS-non-adherence. Clinical tools indicating non-adherence could be helpful to improve management of this patient group. Objective: To assess whether the available tools for measuring concerns regarding corticosteroids, the TOPICOP scale and the 0-10 Visual Analogue Scale (VAS), could help to detect non-adherence to TCS. Methods: In 75 patients with concerns regarding TCS use both the TOPICOP scale and VAS were anonymously assessed. A comparison was made between TCS-adherent and non-adherent patients regarding the intensity and characteristics of their concerns. Results: The intensity and quality of the concerns varied broadly among the patients. When using the VAS, a score of >= 5 detected 87% of non-adherent patients. The answers to the TOPICOP scale did not discriminate non-adherent from adherent patients. Conclusion: Using the VAS to assess concerns to use TCS could help identify patients at risk of TCS-non-adherence and facilitate discussion with the patient about potential non-adherence in a more substantiated, non-judgemental way.
