概括
危机链接热线显示,多伦多交通委员会地铁自杀事件的暂时,无意义的减少. 媒体报道的自杀事件与自杀率的增加有关,影响了预防策略.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 心理健康研究 心理健康研究
背景情况:
- 多伦多交通委员会 (TTC) 地铁系统在1954年至1980年期间经历了大量的自杀事件.
- 2011年,TTC推出了"危机链接" (Crisis Link),这是一个预防自杀的热线,以支持乘客.
- 媒体对自杀事件的报道是影响自杀行为的潜在上游因素.
研究的目的:
- 调查危机链接热线对TTC地铁系统中自杀率的影响.
- 检查媒体报道TTC自杀事件与随后的自杀率之间的关联.
- 通过了解干预措施和媒体报道的影响,为预防自杀政策提供信息.
主要方法:
- 利用了来自TTC和验尸官办公室 (1998-2021) 的自杀数据.
- 集成的危机链接来自大多伦多地区救援中心的呼叫数据 (1998-2021).
- 员工中断时间序列分析,以评估危机链接,媒体文章和季度自杀率之间的关系.
主要成果:
- 在1998年至2021年期间,TTC地铁系统共发生了302起自杀事件.
- 危机链接的引入与直接季度自杀率的非显著下降有关 (IRR=0.64).
- 危机后的每个季度,自杀率平均增加了2% (IRR=1.02),而前一个季度的每个媒体文章与自杀率增加了2% (IRR=1.02).
结论:
- 危机链接热线显示,地铁自杀事件的短期减少,虽然不显著.
- 缺乏持续影响可能部分是由于媒体报道与自杀率增加之间的关联.
- 调查结果强调,需要考虑媒体在全球公共交通系统自杀预防策略中的作用.

Introduction To Survival Analysis
220
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.

Assumptions of Survival Analysis
123
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Actuarial Approach
75
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

Comparing the Survival Analysis of Two or More Groups
177
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Truncation in Survival Analysis
199
Truncation in survival analysis refers to the exclusion of individuals or events from the dataset based on specific criteria related to the time of the event. This exclusion can happen in two primary forms: left truncation and right truncation.
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are...

Censoring Survival Data
82
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...
