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.

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...

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...

Area of Science:

  • Neurodegenerative diseases
  • Gerontology
  • Public Health

Background:

  • Alzheimer's disease (AD) is a common neurodegenerative disorder in the elderly.
  • The exact causes of AD are unknown, highlighting the need for early detection.
  • Early intervention is crucial for managing AD progression.

Purpose of the Study:

  • To develop an Alzheimer's Risk Index (ARI).
  • The ARI aims to assess socio-demographic, lifestyle, medical, behavioral, and neuropsychological factors linked to AD risk.
  • This index will help evaluate risk for cognitive decline.

Main Methods:

  • Utilized data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database.
  • Included participants aged 55 to 91.
  • Employed Factor Analysis (FA) and Principal Component Analysis (PCA) for index development.

Main Results:

  • Developed a novel Alzheimer's Risk Index.
  • The study explored potential associations between the ARI and AD prevalence.
  • Insights into factors contributing to AD risk were gained.

Conclusions:

  • The Alzheimer's Risk Index is designed for public accessibility.
  • It serves as a preliminary tool for individuals to assess their risk.
  • The index encourages seeking medical diagnosis for early AD detection.
