Objective: The objective of this study is to investigate the impact of using the VBHC framework for the management of psoriasis. Study design: The IRIS (value In psoRiasIS) study will be a prospective clinical trial in which new patients attending the psoriasis clinic (PsoPlus) of the Ghent University Hospital will be followed up during a period of 1 year. Study population: The study population consists of psoriasis patients attending the PsoPlus for the first time. Main study parameters/endpoints: The main outcome is to determine the value created for new psoriasis patients in PsoPlus over a period of 1 year. Thus, the main study parameters pertain to clinically and patient reported outcomes as well as the full cost for treating patients under the year of review, including referrals to other departments. Secondary outcomes are related to comorbidity control, individual outcomes and determining cost drivers. In addition, a bundled payment scheme should be determined as well as potential improvements in the treatment process.
