Background In dermatology, the applications of machine learning (ML), an artificial intelligence (AI) subset that enables machines to learn from experience, have progressed past the diagnosis and classification of skin lesions. A lack of systematic reviews exists to explore the role of ML in predicting the severity of psoriasis.Objectives To identify and summarize the existing literature on predicting psoriasis severity using ML algorithms and to identify gaps in current clinical applications of these tools.Methods OVID Embase, OVID MEDLINE, ACM Digital Library, Scopus and IEEE Xplore were searched from inception to August 2024.Results In total, 30 articles met our inclusion criteria and were included in this review. One article used serum biomarkers, while the remaining 29 used image-based models. The most common severity assessment score employed by these ML models was the Psoriasis Area and Severity Index score, followed by body surface area, with 15 and 5 articles, respectively.Conclusions The small size and heterogeneity of the existing body of literature are the primary limitations of this review. Progress in assessing skin lesion severity through ML in dermatology has advanced, but prospective clinical applications remain limited. ML and AI promise to improve psoriasis management, especially in nonimage-based applications requiring further exploration. Large-scale prospective trials using diverse image datasets are necessary to evaluate and predict the clinical value of these predictive AI models. This systematic review evaluates machine learning (ML) applications in predicting psoriasis severity, analysing 30 articles that predominantly use image-based models. It highlights the prevalent use of the Psoriasis Area Severity Index score, noting the limited size and diversity of current studies. The review emphasizes the potential of ML in dermatology, suggesting further exploration and larger-scale trials for improved psoriasis management.
