Abstract
BACKGROUND Healthcare professionals (HCPs) should strive to create the maximum value for their patients in which value is defined as the patient-relevant health outcomes achieved per costs made. However, currently it remains difficult to determine which outcomes matter to an individual psoriasis patient. OBJECTIVE To define outcome profiles, or so called 'patient value profiles', within a cohort of psoriasis patients that can be translated to daily practice to increase value for the individual patient. METHODS Hierarchical clustering on principal components (HCPC) was used to identify groups of patients sharing the same profile within an outcome ranking exercise. Once the clusters were defined, their characterization was provided based on a V-test. In a final step, a multi-class decision tree (MDT) based on relevant socio-demographic and clinical variables was built to allocate patients to a cluster. RESULTS In the ranking exercise 120 patients participated. The median age was 50.0 (IQR 25.0) years and 36.7% were female. Median PASI score was 2.4 (IQR 5.2) and median duration of psoriasis was 17.0 (IQR 20.0) years. Primary treatment varied from topicals to biologicals. We found three distinct patient value profiles in this cohort (QoL, cost and treatment). A MDT was built which had an accuracy of 64%. CONCLUSION We found three distinct patient value profiles in a cohort of psoriasis patients and patients can be easily assigned to one of these profiles based on a MDT. HCPs can use these profiles to steer psoriasis management accordingly allowing for a more goal-orientated approach.

Abstract
BACKGROUND With the current trend in healthcare moving towards a more value-based approach, it is essential to understand what value encompasses. OBJECTIVES To develop an actionable value-based outcome set (VOS) for daily practice. METHODS A mixed method approach was used consisting of four phases. Formerly, a systematic review was conducted, providing an overview of all patient-relevant outcomes defined in current literature. These 23 outcomes were then presented to a group of patients, using a modified nominal group technique (NGT), to establish whether these results represented all of their relevant outcomes. Subsequently, these outcomes were ranked according to importance by patients attending our academic specialized psoriasis clinic. A review of the literature was performed to assess which instruments were available and suitable to evaluate the outcomes in this VOS. Finally, a pilot feasibility test was performed amongst patients. RESULTS Of the 23 outcomes, two were omitted from the ranking exercise after the NGT. In the ranking exercise, 120 patients participated. The median age was 50.0 (IQR 25.0) years and 36.7% were female. Median PASI score was 2.4 (IQR 5.2), and treatments varied from topicals to biologicals. The outcomes scored as most important were symptom control, treatment efficacy, confidence in care and control of disease. The least important outcomes were comorbidity control, productivity and cost of care. A significant difference was shown between the ranking of the outcomes (p < 0.001). In total, 12 instruments were selected, which are reported by both patient and provider, to measure the outcomes in this VOS. Median completion time for the patient part was 30 min (IQR 2.8). CONCLUSIONS This VOS is a first proposal to evaluate psoriasis care in a value-based manner. Measuring these outcomes can enable us to critically appraise and improve current care processes, within the reality of available resources, thereby increasing value for patients.

Abstract
Objectives: Psoriasis is a chronic skin disease requiring a multidimensional approach, given its varying appearance, presence of comorbidities and complex treatment regimens. Psoriasis care is however often performed fragmented and, in case of flares, reactive with little integrated information on and for the patient. Literature suggests a multileveled approach of psoriasis, but the effects of its implementation have not yet been validated. The aim of this study is to analyze the impact of a multileveled psoriasis consultation format, named PsoPlus, which has been implemented since 2012 in the Department of Dermatology at Ghent University Hospital in Belgium.Methods: The patient population was divided into two groups: one following the regular consultation and one following the PsoPlus format. Demographic data, clinical outcome and treatment approach of psoriasis patients were compared.Results: Patients who opted for the specialized PsoPlus consultation were younger and had longer disease duration. Decision parameters such as disease severity and quality of life were reported more often in the PsoPlus group. In the latter, a higher rate of patients were started on systemic therapy compared to the regular consultation group, and reporting on adverse events was done more frequently.Conclusion: The implementation of a specialized consultation with comprehensive guidance facilitates documentation on disease-relevant parameters such as disease severity and quality of life. This format can be seen as a guidance for capturing data in a structured manner, with evidence showing that it significantly impacts treatment decision, treating not only psoriasis but the patient as a whole.

Abstract
OBJECTIVE Treat-to-target (T2T) is an algorithm to reach a predefined outcome. Here, we define a T2T outcome for moderate-to-severe psoriasis vulgaris. METHODS Briefly, the study included a literature review, discussions with key opinion leaders, recruitment of additional dermatologists with experience in managing moderate-to-severe psoriasis, 3 eDelphi survey rounds and a patient focus group. Relevant topics were selected during discussions prior to the survey for the statements. Surveys were based on the eDelphi methodology for consensus-building using a series of statements. Consensus was defined as at least 80% of participants agreeing. A psoriasis patient focus group provided feedback on topic selection and outcome. RESULTS A total of 5 discussions were held, and 3 eDelphi rounds were conducted with an average of 19 participants per round. The T2T outcome was set assuming shared decision between patient and dermatologist, awareness and referral for comorbidities by the dermatologist and appropriate treatment adherence by the patient. We defined 'ideal' and 'acceptable' targets; the latter referring to conditions restricting certain drugs. The T2T outcome was multidimensional, including ≥ ΔPASI90/75 or PGA ≤ 1, itch VAS score ≤ 1, absence of disturbing lesions, DLQI ≤ 1/3, incapacity daily functioning VAS score ≤ 1, safety ≤ mild side-effects and full/mild tolerability of treatment for the ideal and acceptable target, respectively. Finally, time to achieve the T2T outcome was set at 12 weeks after initiation for all treatments. At all times, safety should not exceed the presence of mild side-effects. CONCLUSION With this novel T2T composite outcome for psoriasis, clinicians and patients can make shared decisions on the treatment goals they envisage, as a guidance for future treatment steps - leading to a tight control management of the disease.

Abstract
Engaging global key opinion leaders, the International Psoriasis Council (IPC) held a day-long roundtable discussion with the primary purpose to discuss the treatment goals of psoriasis patients and worldwide barriers to optimal care. Setting clear expectations might ultimately encourage undertreated psoriasis patients to seek care in an era in which great gains in therapeutic efficacy have been achieved. Here, we discuss the option for early treatment of all categories of psoriasis to alleviate disease impact while emphasizing the need for more focused attention for psoriasis patients with mild and moderate forms of this autoimmune disease. In addition, we encourage policy changes to keep pace with the innovative therapies and clinical science and highlight the demand for greater understanding of treatment barriers in resource-poor countries.

Abstract
The concept of personalized medicine is a new individualized approach which helps application of the targeted therapy. In fact, tailored medicine is mostly present in the field of life-threatening diseases such as oncology. However, skin diseases as such might be regarded as a potential area of implementation of this approach in the future. Stratified medicine in polygenetic and heterogeneous diseases, such as psoriasis, is more complex. Rapid development of science and novel molecular techniques led to better understanding of molecular pathogenetic pathways of many diseases including psoriasis. Identification of the particular immunopathogenetic pathways led to further development of targeted therapies such as biologic drugs. Actually the goal of individualized therapy is to determine the identical homogenous subgroups of patients, according to a biomarker, in which the response to that therapy will be the best and will carry the lowest risk of side effects. This review attempts to analyze the associations between polymorphisms of certain genes and the increased risk of developing psoriasis or psoriatic arthritis. The review of literature has also included the studies investigating the associations between gene polymorphisms and response to biologic therapy in psoriasis and psoriatic arthritis patients.
