- 在瘤学瘤学.
- 生物统计学 生物统计学
- 临床预后 临床预后
背景情况:
- 1987年开发的曼彻斯特分数分层化了小细胞肺癌 (SCLC) 患者的死亡风险.
- 外部验证对于预后模型至关重要,但往往缺乏,阻碍了临床采用.
- 这项研究验证了曼彻斯特分数在未经选择的当代SCLC患者队列中.
研究的目的:

4.1K
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

423
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
