研究目的: |
探讨前瞻性观察性研究中,对非危重表现早产儿采取“延迟抽血/观察”策略的安全性(漏诊率)与有效性(预测价值),并分析LOS病原菌特征。 |

|
Objectives of Study: |
To investigate the safety (missed diagnosis rate) and effectiveness (predictive value) of adopting the "delayed blood sampling/observation" strategy in preterm infants with non-critical manifestations through a prospective observational study, and to analyze the characteristics of pathogens causing late-onset sepsis (LOS). |

|
盲法: |
尽管本研究为前瞻性观察性队列研究(非干预性设计),但通过以下措施可模拟盲法原则,降低测量偏倚和评估偏倚风险: 测量偏倚:症状分级、实验室检查结果判读可能受研究者主观影响; 评估偏倚:医生对抽血时机的决策可能受初始症状严重程度预判干扰。 |
|
Blinding: |
Although this study is a prospective observational cohort (non-interventional), the following measures were taken to approximate blinding and minimise the risks of measurement and assessment bias: Measurement bias: grading of symptoms and interpretation of laboratory results could be influenced by investigators’ subjective judgement. Assessment bias: clinicians’ decisions on when to draw blood might be affected by their initial perception of symptom severity. |
