Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

科学领域:

  • 神经学和衰老研究研究
  • 发现神经退行症的生物标志物
  • 临床试验设计优化

背景情况:

  • 老年人衰老和认知健康评估 (ACHIEVE) 试验发现,听力干预在一个子组中减缓了48%的认知衰退.
  • 需要进一步研究以了解听力干预对神经退行生物标志物的影响.

研究的目的:

  • 测试听力干预是否与3年后神经退行性血液生物标志物 (GFAP和NfL) 的改善有关.
  • 评估是否结合认知和生物标志物结果可以提高临床试验设计中的统计能力.

主要方法:

  • 一个随机试验,涉及70-84岁的未经治疗的听力损失和没有重大认知障碍的成年人.
  • 血生物标志物 (GFAP,NfL) 在3年后的亚样本 (n=540) 中测量;ARIC参与者 (n=164) 也具有基线血.
  • 回归模型分析了听力干预与3年生物标志物和认知变化的关联,包括复合得分.

主要成果:

  • 在组合或新组中,在3年后的生物标志物水平中没有发现显著差异.
  • 在社区动脉样硬化风险 (ARIC) 参与者中,听力干预与较低的3年GFAP和NfL水平有关.
  • 在ARIC参与者中,干预与较慢的认知衰退和较慢的GFAP增长率相关.
  • 综合认知和生物标志物得分显示,ARIC亚组中,与仅认知相比,统计能力增加.

结论:

  • 听力干预在ARIC参与者中对神经退行生物标志物产生了积极影响,与认知益处保持一致.
  • 这些发现提供了与听力干预相关的大脑变化的客观证据.
  • 综合结果测量可能为未来的大脑健康临床试验提供更强大的方法.
