Stress and Mental Health01:30

Stress and Mental Health

955
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...

Survey Safety

413
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Relative Risk01:12

Relative Risk

2.2K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Higher Mental Functions of the Brain: Language

3.9K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Prediction Intervals01:03

Prediction Intervals

3.4K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

科学领域:

  • 精神病学信息学 精神病学信息学
  • 医疗保健中的机器学习
  • 患者安全技术技术

背景情况:

  • 患者安全事件在精神病学环境中是一个重大问题,目前的早期预警系统 (EWS) 发展不足,往往是反应性的.
  • 传统的风险评估工具,比如情境侵略 - 住院版本 (DASA-IV) 的动态评估,对不良事件的预测准确性有限.

研究的目的:

  • 引入心理健康事件预测风险识别 (PRIME) 工具,这是一个基于深度学习的新型EWS.
  • 利用纵向精神病学电子病历 (EMR) 数据来预测24小时内发生的不良事件.

主要方法:

  • 一个回顾性队列研究在精神健康护理的Waypoint中心,包括4651名患者和超过40万次遭遇.
  • 训练具有注意力机制的循环神经网络,对多变量时间序列EMR数据进行风险预测.
  • 与DASA-IV工具和其他使用AUC和回忆指标的机器学习模型进行比较.

主要成果:

  • 带有注意力机制的长期短期记忆网络实现了高预测性能,AUC为0.83.
  • 与DASA-IV工具相比,PRIME表现出显著的改善,AUC差异为0.20 (0.83对0.61).
  • 该研究强调了机器学习模型在心理健康方面的积极风险管理方面的潜力.
