Multidisciplinary approach to psoriasis in the Spanish National Health System: A social return on investment study.

Introduction: Psoriasis is a chronic disease in which patients feel stigmatization, social rejection, and suffer from low self-esteem. There are still unmet needs that make it necessary to define a new multidisciplinary approach to provide benefits not only to patients and their families but also to the Spanish National Health System (SNHS) and society. The aim was to define a new approach to better address the unmet needs of patients with psoriasis within the SNHS and to measure its impact from a social perspective, that is, in clinical, health care, economic, and social terms.

Methods: Multidisciplinary experts identified, agreed on, and selected several health care interventions that were feasible for implementation in the SNHS. This process was carried out in four different areas: diagnosis, mild psoriasis, moderate psoriasis, and severe psoriasis. To estimate investment and social return, the social return on investment (SROI) method was used.

Results: The new approach to psoriasis management in the SNHS comprised 18 proposals. The investment needed for the implementation of this new approach would amount to €222.77 million and its return to €1,123.11 million. This would yield a SROI ratio of €5.04 for every euro invested.

Conclusion: The new approach to psoriasis management would yield a positive social return. The results will allow optimal strategic planning adapted to each assistance situation, to achieve a comprehensive and multidisciplinary approach.
