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:

  • Gerontology
  • Neurology
  • Public Health

Background:

  • Dementia prevalence is rising globally due to aging populations.
  • Cognitive decline screening rates are low in Thailand, hindered by healthcare professional shortages and limited specialized services.
  • A voice-based, Self-Administered test for Memory, Orientation, and flueNcy for the Geriatric population (SAMONG) was developed to improve accessibility.

Purpose of the Study:

  • To assess the diagnostic accuracy of the SAMONG test in identifying dementia among older Thai adults.
  • To evaluate the effectiveness of a web-based, voice-activated cognitive screening tool.
  • To determine the potential of SAMONG to enhance dementia screening accessibility.

Main Methods:

  • A cross-sectional study enrolled adults aged 60+ diagnosed with or without dementia by geriatricians (DSM-5 criteria, CDR).
  • Participants completed the SAMONG test (registration, orientation, fruit fluency, 3-word recall) in a standardized setting.
  • Diagnostic performance was analyzed using ROC/AUC; automatic interpretation accuracy was compared to human interpretation via Bland-Altman analysis.

Main Results:

  • SAMONG demonstrated high diagnostic accuracy with an overall AUC of 0.899.
  • An optimal cutoff score of ≥2/5 yielded 97% sensitivity and 72% specificity.
  • Fruit fluency alone showed strong performance (AUC 0.884), with a cutoff of ≥10 yielding 79% sensitivity and 85% specificity.

Conclusions:

  • SAMONG exhibits excellent diagnostic accuracy for dementia screening in Thai older adults.
  • The test's accessibility and promising performance suggest potential for broader implementation in diverse settings.
  • SAMONG can improve cognitive screening efficiency and reduce healthcare system strain.
