61 From the point of view of physician motivation, correct diagnosis and a comprehensive approach to the management of patients with comorbid pathology allow [5, 6, 7]:  Improve the effectiveness of prescribed therapy;  Avoid the unjustified use of systemic immunosuppressive agents;  Reduce the frequency of relapses and the duration of treatment;  Improve patients' quality of life and long-term treatment outcomes. The scientific novelty of this work lies in the consideration of the comorbidity of nail psoriasis and onychomycosis in the context of public health, taking into account its impact on the organization of medical care, clinical decisions of doctors and medical and social consequences. The work emphasizes the need for a systematic approach to the diagnosis of nail lesions in patients with psoriasis as a condition for improving the safety and effectiveness of treatment. The practical significance of the study lies in the formation of clinical vigilance regarding possible fungal nail lesions in patients with psoriasis and the justification of routine mycological screening before prescribing systemic therapy. The proposed approaches can be directly implemented into the daily practice of dermatologists and primary care physicians, contributing to the optimization of treatment tactics and reducing the burden on the healthcare system. The aim of the study is to comprehensively analyse the comorbidity of nail psoriasis and onychomycosis from a public health perspective, taking into account clinical, epidemiological and organizational aspects, as well as to justify the practical feasibility of a systematic approach to the diagnosis and management of this category of patients in everyday clinical practice. Research objective. To assess the significance of comorbid nail disease from a public health perspective, in particular its impact on treatment effectiveness and patients' quality of life. Materials and methods. The study was conducted in the format of an analytical review article using the principles of evidence-based medicine and public health approaches. The aim of the analysis was to summarise current scientific data on the
