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...

Area of Science:

  • Gerontology
  • Neurology
  • Health Services Research

Background:

  • Keck Medicine of USC (KMUSC) serves a diverse population of 16 million, with 800,000 outpatient visits annually.
  • A population-based plan for Mild Cognitive Impairment (MCI)/dementia detection and diagnosis is crucial for KMUSC's Brain Health Program.
  • Integrating a Brain Health Navigator (BHN) can accelerate diagnosis and facilitate future program expansion.

Purpose of the Study:

  • To implement a Brain Health Navigator (BHN) model to improve the detection and diagnosis of cognitive impairment.
  • To streamline and standardize the diagnostic process for patients with potential MCI/dementia.
  • To enhance collaboration between primary and specialty care for cognitive impairment management.

Main Methods:

  • An interdisciplinary team is designing the integration of the BHN role into primary and specialty care workflows.
  • A pilot program will launch at USC Healthcare Center 2, incorporating co-located primary care and memory specialty services.
  • The BHN will facilitate patient assessment, referrals, and post-diagnostic care coordination.

Main Results:

  • The BHN-facilitated pathway is expected to increase the diagnosis of cognitive impairment.
  • Timely and targeted referrals for patients with cognitive impairment will be achieved.
  • Collaboration on post-diagnosis care pathways between primary and specialty care will be explored.

Conclusions:

  • The BHN model supports boundary-spanning roles across care settings for effective diagnosis and care.
  • This approach facilitates a timely, accurate, and efficient journey for patients with cognitive impairment.
  • The model is designed for implementation at KMUSC and similar health systems.
