Out-of-pocket expenditures in France to manage psoriasis in adult patients: results from an observational, cross-sectional, non-comparative, multicentre study.

BACKGROUND: In 2018 in France, overall mean health-related out-of-pocket (OOP) expenditures were 214.00€/year/patient. AIM: To evaluate OOP expenditures for psoriasis patients in France. METHODOLOGY: Observational, cross-sectional, non-comparative, multicentre study in 3000 patients with clinically confirmed psoriasis who responded to a specific digital questionnaire collecting demographic and socio-economic characteristics, assessing the 3 domains (severity, psychosocial impact and past history and interventions) of the patient's Simplified Psoriasis Index (sa-SPI) and expenditures to manage psoriasis, including OOP. Multivariate linear regression was conducted to search for factors associated with higher OOP. RESULTS: In total, 2681 patients completed the questionnaire and, of those, 2562 provided clinically validated data. Overall, 60% were women; the mean age was 49.4 ± 14.8 years. 30% of the patients declared that they suffered from psoriatic arthritis. The final mean sa-SPI core was 10.86 ± 9.70. Of these 2562 patients, 243 (9.5%) had severe, 442 (17.3%) moderate and 1877 (73.3%) mild psoriasis. In addition, 932 (36.4%) patients reported facial involvement, 724 (28.25%) genital impairment and 1124 (43.8%) lesions on the limbs. Mean OOP expenditures to manage psoriasis per patient were 531.00€, 439.74€ ± 939.85€ for patients with mild, 791.06€ ± 1367.67€ with moderate and 1077.64€ ± 1680.14€ for patients with severe psoriasis. For patients with psoriasis in the genital area, the median amount of expenditures (251.17€; CI95% [138.35;363.99]) was significantly higher than that for the face (183.85€; CI95% [78.76;288.94]) or limbs (199.96€; CI95% [93.77;306.15); (P < 0.001). More than 90% of the patients had OOP expenditures for over-the-counter products (97.5%) and alternative care (92.0%), especially for emollients and/or hydrating products. CONCLUSION: In France, in 2019, OOP expenditures to manage psoriasis were on average more than twice as high as the overall mean health-related OOP expenditures estimated by the French Health Agency in 2018. These results should lead health authorities to review certain standards of healthcare reimbursement.

[French adaptation of a new score for global assessment of psoriasis severity: The Simplified Psoriasis Index (SPI)]. / Adaptation française d'un nouveau score destiné à l'évaluation globale de la sévérité du psoriasis : l'Indice Simplifié du Psoriasis (Simplified Psoriasis Index, SPI).

OBJECTIVE: Although several scores exist to assess psoriasis severity, most have marked limitations that rule out their use in routine clinical practice. A new score, the Simplified Psoriasis Index (SPI), has recently been developed and validated in adults in Britain for such use. It has separate components for current severity (SPI-s), psychosocial impact (SPI-p) and past history and interventions (SPI-p), and it is suitable for either professional assessment or patient self-assessment. The aim of this work was to produce a validated translation of SPI into French (as spoken in France). METHODS: The index was translated and validated using a strict methodology comprising respectively five and eight phases for the professional (proSPI) and self-administered instruments (saSPI). Translation of the saSPI instrument also involved a cognitive debriefing with five psoriasis patients. RESULTS: Linguistic discrepancies and subtle differences of meaning arising during the process were closely examined. The developer of the instrument ensured conceptual accuracy. A panel of health experts guaranteed that medical terms were correctly translated. Five patients with plaque psoriasis (two female and three male of median age 45 years [range: 31-78]) tested the SPI-p version during cognitive interviews and found the questionnaire clear and easy to understand. CONCLUSION: Validated French translations of both SPI instruments are now available for use in routine clinical practice. Further investigations are currently underway to validate the psychometric properties of the instrument.

Topical vitamin D analogues alone or in association with topical steroids for psoriasis: a systematic review.

OBJECTIVE: The objective of this systematic review was to prepare for evidence-based recommendations on the use of vitamin D analogues, and their combination with topical steroids in psoriasis. METHODS: Literature systematic review performed in May 2011. The Cochrane, PubMed and Embase databases were systematically searched with different combinations: including Psoriasis AND calcipotriol expanded to all vitamin D analogues. To assess efficacy across studies, we used two predefined criteria to account for the numerous endpoints found in the literature, 'Treatment success' corresponding to 90% improvement in severity and 'Satisfactory response' corresponding to 75% improvement. We conducted a meta-analysis comparing the efficacy of vitamin D analogues plus topical steroids (VDS) vs. vitamin D analogues alone (VD). To determine the relative cost-efficacy of the topical drugs available on the market, cost/efficacy ratios were calculated for each product according to the approved therapeutic regimen. RESULTS: 51 articles were selected. The application duration varied between three to 52 weeks across studies. VD as monotherapy had a satisfactory response rate between 22% to 96% and a treatment success rate ranging from 4% to 40%. VDS had a satisfactory response rate between 35% to 86% and a treatment success rate ranging from 27% to 53%. A meta-analysis found a probability of success twice higher with VDS than with VD in adult plaque psoriasis. The cost/efficacy ratio was evaluated as 1.2-1.8 times higher for VDS than for VD. CONCLUSION: VDS is twice more effective than VD and displays a better cost per success. Additional studies are needed to clarify maintenance treatment, impact on quality of life, treatment of non-plaque psoriasis. It will be important to harmonize outcome measures in future studies with topical agents in psoriasis to better appraise their efficacy.

[Psoriasis: Practical pre-therapeutic assessment]. / Psoriasis : bilan préthérapeutique pratique.

Psoriasis is a chronic disease for which treatment is not definitive and is likely to vary over time. A number of parameters must be taken into consideration for the initial assessment of psoriasis patients requiring systemic therapy, with the latter being based primarily on the previous drug history, objective medical evaluation of the psoriasis and comorbidities, and determination of any medical contraindications to the various treatments available. However, social factors, the patient's lifestyle, level of understanding and compliance, as well as various economic factors must also be borne in mind when deciding upon a therapeutic approach. A complete dossier setting out the patient's drug history and disease history forms the key reference and is essential for treatment monitoring and adjustment, reflecting changes in the course of the skin disease and in the patient's medical history. This information must be made available to all doctors involved in the patient's treatment in order to ensure optimal management.

Cost-effectiveness of surveillance of stage I melanoma. A retrospective appraisal based on a 10-year experience in a dermatology department in France.

BACKGROUND: There is no agreement about surveillance after resection of a stage I melanoma. OBJECTIVE: We assessed the cost-effectiveness of this surveillance. METHODS: Out of 912 patients with stage I (and Clark's level > or = II) melanoma examined from 1981 to 1991, only 528 were regularly followed in our department. RESULTS: 115 out of 528 relapsed; 33% were detected by the patient himself, 16% by the referring physician and 39% were detected in our department. Chest X-ray or abdomen ultrasonography revealed only 10% of relapses; CT scans were useless. There was a huge gap between the cost-effectiveness of clinical examinations and radiology. The time between relapse and the last check-up in our department was less than 4 months in one third of the metastases. CONCLUSIONS: In stage I melanoma, only clinical examination is really cost-effective in the detection of metastases. However, many metastases are likely to become prominent between two examinations if patients are examined less than 3 times a year. A progressive decrease in frequency is thus not advisable, until the risk is considered low enough to stop follow-up.
