Traditionally, VTE risk assessment has been predominantly conducted by healthcare providers, which is time-consuming and laborious. In recent years, research on patient self-assessment has increasingly attracted attention. This article mainly discusses the feasibility, effectiveness, and application prospects of patient self-assessment of VTE risk. Through the collation and analysis of multiple studies, it was found that the the Caprini risk score of venous thromboembolism based on the patient self-assessment model had shown certain effectiveness in different language versions and patient groups. It can significantly improve the efficiency of assessment, promote patients' attention to health and participation, and can be used as an effective supplement to the assessment of medical staff. However, during the patient self-assessment process, cognitive biases are prone to occur in some assessment options, and it is difficult for patients with special disease conditions to independently complete self-assessment. Therefore, in the future, it is necessary to further optimize assessment tools, leverage new technologies to achieve automated and intelligent assessment, and carry out high-quality multi-center and large-sample studies to improve the accuracy and efficiency of VTE risk assessment, and promote patient participation and improvement of clinical practice.</p>","PeriodicalId":24023,"journal":{"name":"Zhonghua yi xue za zhi","volume":"105 30","pages":"2531-2535"},"PeriodicalIF":0.0,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144817696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
