Early detection and treatment are essential to improve the prognosis of patients with psoriatic arthritis. Nail psoriasis is a known risk factor and a predictive symptom for psoriatic arthritis. Assessment of clinical manifestations of nail psoriasis together with evaluation using advanced technology has made it possible to achieve early diagnosis of psoriatic arthritis. This review summarizes diagnostic methods of psoriatic arthritis and nail psoriasis in recent years, and analyzes the latest studies on the correlation between psoriatic arthritis and nail psoriasis, in order to facilitate early diagnosis of psoriatic arthritis through clues of nail psoriasis.

Objective:To systematically retrieve the assessment tools for patient care complexity at home and abroad, and compare their release institutions, formation process, applicable population, assessment methods and main contents.Methods:Articles on patient care complexity assessment tools was retrieved through computers in PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, WanFang Data, China Biomedical Database, and VIP Database. The retrieval time limit was from the establishment of the database to July 2, 2022. Excel 2019 was used to extract the name, release institution, evaluation method, main content and other information of the assessment tools and compare the content characteristics of the assessment tools.Results:A total of 26 assessment tools for patient care complexity were included in this study, involving 37 articles, mainly observational studies. The 26 tools were mainly issued by institutions of higher learning, and most of them were applicable to ordinary inpatients. The assessment contents included the general situation of the patient, severity of the disease, treatment items, mental cognitive function, mental health, socio-economic support and compliance.Conclusions:At home and abroad, the patient care complexity evaluation tools are mainly used to evaluate ordinary adult inpatients. There are few tools to evaluate children, the elderly, Intensive Care Unit (ICU) and other special types of patients, and there is a lack of relevant intervention research. In China, there are few tools for evaluating patient care complexity involving indicators related to mental cognitive function, which suggests that nurses can consider the mental cognitive function of patients when building relevant assessment tools in the future. In addition, the application effect of such tools in patient risk identification and safety management, nursing human resource allocation and other fields should be verified.
