Cohort study 

研究目的:

本研究旨在系统评估慢性自发性荨麻疹(CSU)患者从症状发作到确诊的时间延迟,识别导致诊断延迟的患者、临床及医疗系统相关影响因素,评估延迟对患者生活质量、心理健康和医疗资源利用的影响,并通过定性访谈深入理解患者的就医体验与障碍,最终为优化CSU早期诊断路径提供循证依据和实践策略。  

Objectives of Study:

This study aims to systematically evaluate the time delay from symptom onset to diagnosis in patients with chronic spontaneous urticaria (CSU), identify patient-, clinical-, and healthcare system-related factors contributing to diagnostic delay, assess the impact of such delay on quality of life, mental health, and healthcare utilization, and gain in-depth insights into patients’ diagnostic journey and barriers through qualitative interviews. Findings will inform evidence-based strategies to optimize early diagnosis pathways for CSU.

纳入标准:

Inclusion criteria

排除标准:

1) 未确诊CSU,如仅诊断为“荨麻疹”或急性荨麻疹; 2) 确诊为慢性诱发性荨麻疹(CIndU)或其他皮肤病(如荨麻疹性血管炎、湿疹); 3) 病历缺失症状发作或确诊时间,无法计算诊断延迟; 4) 年龄<18岁或>80岁,或存在严重认知障碍,无法完成问卷/访谈; 5)合并严重系统性疾病(如系统性红斑狼疮、恶性肿瘤),可能干扰CSU诊断或心理评估; 6) 拒绝签署知情同意书。

Exclusion criteria:

1) Unconfirmed CSU, such as only diagnosed as "urticaria" or acute urticaria; 2) Diagnosed as chronic inducible urticaria (CIndU) or other skin diseases (such as urticarial vasculitis, eczema); 3) The medical record lacks the time of symptom onset or diagnosis, making it impossible to calculate the diagnostic delay; 4) Age less than 18 years or more than 80 years, or having severe cognitive impairment, unable to complete the questionnaire/interview; 5) Complicated with severe systemic diseases (such as systemic lupus erythematosus, malignant tumors), which may interfere with the CSU diagnosis or psychological assessment; 6) Refused to sign the informed consent form.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用自行设计的纸质病例记录表(CRF)采集数据,包括病历回顾信息和问卷结果。数据经双人核对后录入加密Excel表格,存储于医院皮肤科专用电脑,实施权限管理和定期核查。未使用ResMan等电子数据采集系统(EDC)。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study uses a self-designed paper-based Case Record Form (CRF) to collect data, including retrospective medical record information and questionnaire responses. Data are double-checked by two researchers and entered into password-protected Excel files stored on a dedicated computer in the Department of Dermatology, with access control and periodic verification. No electronic data capture (EDC) system (e.g., ResMan) is used.
