研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

系统分析降钙素原(PCT)动态特征(峰值下降率、谷值水平、达标时间)与脓毒症患者短期(28 天 / 90 天死亡率、器官功能损伤)及长期(6 个月 - 1 年再感染率、再住院率)预后的关联,明确其预后评估价值。  

Objectives of Study:

To systematically analyze the correlation between the dynamic characteristics of procalcitonin (PCT) (peak decline rate, trough level, time to reach the standard) and the short-term (28-day/90-day mortality, organ function injury) and long-term (6-month to 1-year reinfection rate, readmission rate) prognosis of patients with sepsis, and clarify its prognostic evaluation value.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.符合《脓毒症 3.0 诊断标准》,存在明确感染证据(血培养 / 痰培养阳性、影像学提示感染灶等),且 SOFA 评分>=2 分; 2.年龄>=18 岁; 3.抗生素治疗时长>=48h; 4.具备完整的降钙素原(PCT)检测数据(检测次数>=3 次)、临床诊疗资料及预后结局信息;

Inclusion criteria

1. Meet the Sepsis-3.0 diagnostic criteria, with clear evidence of infection (such as positive blood culture, positive sputum culture, imaging findings suggesting an infectious focus, etc.) and a Sequential Organ Failure Assessment (SOFA) score >=2; 2. Age >=18 years; 3. Duration of antibiotic treatment >=48 hours; 4. Have complete procalcitonin (PCT) test data (number of tests >=3), clinical diagnosis and treatment records, and prognostic outcome information.

排除标准:

1.合并严重免疫功能缺陷(长期用免疫抑制剂、艾滋病患者)、恶性肿瘤终末期,或为妊娠 / 哺乳期女性;
2.病毒 / 真菌感染为主或非感染性炎症(如自身免疫性疾病、创伤后炎症反应)诱发器官功能障碍;
3.关键临床数据(如 PCT 动态监测结果、预后随访信息)严重缺失;
4.中途转院或自动出院导致随访中断,无法获取完整预后数据者。

Exclusion criteria:

1.Severe immunodeficiency (e.g., long-term use of immunosuppressants, HIV/AIDS), end-stage malignant tumor, or being a pregnant/lactating woman;
2.Organ dysfunction induced mainly by viral/fungal infection or non-infectious inflammation (such as autoimmune diseases, inflammatory response after trauma);
3.Severe lack of key clinical data (such as dynamic PCT monitoring results, prognostic follow-up information);
4.Interruption of follow-up due to transfer to another hospital or voluntary discharge during treatment, resulting in failure to obtain complete prognostic data.
