Shared Decision Making in Psoriasis: A Systematic Review of Quantitative and Qualitative Studies.

There appears to be a need to strengthen the relationship between medical doctors and patients with psoriasis.

The effects of shared decision making in psoriasis are inconclusive, and more research appears necessary to determine the possible benefits of shared decision-making interventions.
