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...

Resumen
Este resumen es generado por máquina.

La Iniciativa de Neuroimagen de la Enfermedad de Alzheimer (ADNI4) utilizó con éxito un modelo de investigación comprometido con la comunidad (CER) para aumentar la participación de los participantes y mejorar la generalización del estudio. Este enfoque mejoró el reclutamiento de diversos orígenes, superando los objetivos iniciales para una representación de datos más amplia.

Área de la Ciencia:

  • Investigación en Neurociencia y Envejecimiento
  • Metodología de Ensayos Clínicos
  • Investigación Participativa Basada en la Comunidad

Sus antecedentes:

  • Garantizar la generalización de los datos de la Iniciativa de Neuroimagen de la Enfermedad de Alzheimer (ADNI) es crucial para avanzar en la investigación.
  • El Núcleo de Participación de ADNI4 utiliza un modelo de investigación comprometido con la comunidad (CER) multifacético para mejorar la participación de los participantes.
  • Este estudio evalúa la eficacia preliminar del modelo CER a través de actualizaciones de inscripción.

Objetivo del estudio:

  • Implementar y evaluar un modelo de investigación comprometido con la comunidad (CER) dentro de ADNI4 para mejorar la participación de los participantes.
  • Aumentar la generalización de los datos del estudio ADNI al involucrar a poblaciones diversas.
  • Evaluar la efectividad de estrategias específicas de CER, incluidas las asociaciones con Organizaciones Comunitarias (CBO) y el despliegue de Enlaces de Investigación Comunitaria (CRL) y Navegadores de Investigación Comunitaria (CRN).

Principales métodos:

  • Un modelo CER que prioriza la creación de confianza, el aprendizaje conjunto y el intercambio de poder con las CBO y los participantes en todas las fases de ADNI4.
  • Asociación con 'Centros Principales' que brindan apoyo para la participación de los participantes, incluidos CRL dedicados.
  • Soporte remoto de CRN a través de teléfono, correo electrónico y chat para abordar las necesidades de los participantes y construir relaciones.

Principales resultados:

  • A enero de 2025, 10 centros principales, 6 CRL y 6 CRN estaban activos, involucrando a 85 CBO y llegando a 7.994 personas a través de 101 eventos comunitarios.
  • Los CRN gestionaron 3.124 comunicaciones, abordando principalmente biomarcadores en sangre, inscripción y consultas relacionadas con el estudio.
  • Los 10 centros principales, que representan aproximadamente el 20% de los centros ADNI, contribuyeron a aproximadamente el 50% de la generalización mejorada en los nuevos participantes reclutados en la clínica.

Conclusiones:

  • ADNI4 ha escalado con éxito un modelo CER integral a nivel nacional, demostrando una mayor participación de los participantes y generalización.
  • Las estrategias implementadas, centradas en la confianza y las asociaciones comunitarias a largo plazo, superaron los objetivos del estudio.
  • Este enfoque ofrece un modelo replicable y escalable para generar datos más generalizables en el campo de la Enfermedad de Alzheimer y las Demencias Relacionadas (AD/ADRD).
