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...

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...

Summary
This summary is machine-generated.

Annual Wellness Visits (AWVs) are linked to earlier identification of mild cognitive impairment (MCI) and Alzheimer's Disease Related Dementia (ADRD) in Medicare beneficiaries. This study highlights AWVs' role in improving cognitive health diagnosis through assessments.

Area of Science:

  • Gerontology
  • Neurology
  • Public Health

Background:

  • Prior research indicates an association between Annual Wellness Visits (AWVs) and early diagnosis of mild cognitive impairment (MCI) in Medicare beneficiaries.
  • Integrating cognitive function assessments before and after AWVs can enhance understanding of this association.

Purpose of the Study:

  • To investigate the association between AWVs and the identification of cognitive impairment, including MCI and Alzheimer's Disease Related Dementia (ADRD).
  • To analyze cognitive function changes using survey data and clinical diagnoses in relation to AWV receipt.

Main Methods:

  • A population-based cohort study utilized Health Retirement Survey (HRS) data linked with Medicare claims from 2011-2019.
  • Propensity score matching compared subjects with AWVs to those without, analyzing cognitive assessments and MCI/ADRD diagnoses within two years post-visit.
  • Langa-Weir Classification was used for cognitive assessment (normal, cognitive impairment no dementia [CIND], probable dementia).

Main Results:

  • AWV receipt was significantly associated with an increased diagnosis of MCI (HR: 1.79) and insignificantly with ADRD (HR: 1.23).
  • Pre-visit cognitive impairment (CIND or probable dementia) strongly predicted subsequent ADRD diagnosis.
  • Among those diagnosed with ADRD, the AWV group showed a lower proportion of "probable dementia" pre-diagnosis and a higher proportion post-diagnosis compared to the non-AWV group.

Conclusions:

  • Medicare AWVs are associated with improved identification of early cognitive impairment.
  • This includes enhanced detection through both clinical diagnoses and survey-based cognitive assessments.
