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...

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:

  • Neuroscience
  • Genetics
  • Public Health

Background:

  • Global dementia research lacks diversity, necessitating inclusion of underrepresented populations like indigenous Africans.
  • The African Dementia Consortium (AfDC) facilitates global research by engaging African researchers across multiple countries.

Purpose of the Study:

  • To recruit and retain 5,000 indigenous Africans for the READD-ADSP study, enhancing diversity in Alzheimer's disease research.
  • To identify and address barriers to participant recruitment and retention in African dementia research.

Main Methods:

  • A case/control study involving 13,000 diverse participants, including 5,000 indigenous Africans, across 10 African countries via the AfDC.
  • Observation of recruitment barriers and development of innovative, context-sensitive interventions.

Main Results:

  • 2457 participants (1251 AD cases, 1246 controls) recruited between June 2023 and January 2025 from diverse African populations.
  • Barriers identified: poor registries, language, myths, stigma, incentive/privacy concerns.
  • Mitigation strategies included community advisory boards, applied theater, and digital media.

Conclusions:

  • Collaboration between ADSP and AfDC is successfully recruiting and retaining participants for the READD-ADSP program.
  • Sustained participant recruitment and retention demonstrate the effectiveness of implemented strategies.
