Steps towards implementation of protocolized dose reduction of adalimumab, etanercept and ustekinumab for psoriasis in daily practice.

BACKGROUND: Dose reduction (DR) of adalimumab, etanercept and ustekinumab has proven to be (cost-)effective in psoriasis patients with low disease activity. Further implementation is needed to establish application of DR for eligible patients. OBJECTIVES: To evaluate the implementation of protocolized biologic DR in daily practice. METHODS: A pilot implementation study was performed in 3 hospitals during 6 months. By combining education and protocol development, involved healthcare providers (HCPs) were directed toward the adoption of protocolized DR. DR of adalimumab, etanercept, and ustekinumab was achieved by stepwise injection interval prolongation. Implementation outcomes (fidelity, feasibility) were assessed. Factors for optimizing implementation were explored in interviews with HCPs. Uptake was measured in patients by chart review. RESULTS: The implementation strategy was executed as planned. Implementation fidelity was less than 100% as not all provided tools were used across study sites. HCPs indicated the feasibility of implementing protocolized DR, although time investment was needed. Identified additional factors for successful implementation included support for patients, uptake of DR into guidelines, and supportive electronic health record systems. During the 6 months intervention period, 52 patients were eligible for DR of whom 26 (50%) started DR. The proposed DR protocol was followed in 22/26 patients (85%) on DR. CONCLUSION: Additional staff for support, extra time during consultations, education on DR for HCPs and patients, and effective tools such as a feasible protocol can lead to more patients on biologic DR.

Evaluation of medium-dose UVA1 phototherapy in localized scleroderma with the cutometer and fast Fourier transform method.

PURPOSE: To evaluate the efficacy of medium-dose UVA1 phototherapy in patients with localized scleroderma. METHOD: A controlled pilot study with medium-dose UVA1 (48 J/cm2) was performed. The results were evaluated by means of a skin score and two objective methods for quantifying sclerosis (cutometer and fast Fourier transform method). Patients were treated 4 times a week for 5 weeks. The follow-up period was 12 weeks. RESULTS: All patients responded to therapy. Skin score and cutometer results showed improvement of skin elasticity of treated skin compared to control skin. Fast Fourier transform measurements showed no change in bundle orientation ratio and spacing. CONCLUSION: We concluded that treatment for 12 weeks 4 times a week with medium-dose UVA1 may be a beneficial therapy and a well-tolerated treatment modality for localized scleroderma (morphea). After 12 weeks, improvement of skin sclerosis can be detected by skin score and cutometer measurements but not by the fast Fourier transform method.
