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...

Summary
This summary is machine-generated.

Persons with Alzheimer's Disease and Related Dementias (ADRD) account for about 1 in 6 emergency department (ED) visits among Medicare beneficiaries. This utilization is disproportionately high in older adults (85+) and dual-eligible populations.

Area of Science:

  • Gerontology
  • Public Health
  • Health Services Research

Background:

  • Emergency Department (ED) visits for Alzheimer's Disease and Related Dementias (ADRD) are increasing.
  • Limited knowledge exists on key risk factors for high ED utilization in ADRD patients.
  • Understanding demographic and ED-level factors is crucial for targeted interventions.

Purpose of the Study:

  • To quantify the proportion of ED visits by persons with ADRD among Medicare beneficiaries.
  • To identify patient- and ED-level characteristics associated with increased ED utilization in this population.

Main Methods:

  • Cross-sectional study using 2019 Medicare Part B claims data.
  • Identified persons with ADRD using the Bynum Standard Algorithm.
  • Analyzed demographic factors (age, sex, race, dual-eligibility) and ED characteristics (region, size, teaching status, ownership).

Main Results:

  • Persons with ADRD comprised a median of 15.6% of all ED visits by Medicare beneficiaries.
  • ADRD patients represented 32.2% of ED visits for those aged 85+ and 30.6% for dual-eligible beneficiaries.
  • ED visit proportions varied significantly by age, dual-eligibility status, geographic region, hospital size, and teaching status.

Conclusions:

  • Persons with ADRD account for a substantial proportion of ED visits, particularly among the oldest and dual-eligible Medicare beneficiaries.
  • Future research should investigate the specific causes of these ED visits and their relationship to dementia care models.
  • Optimizing resource allocation and developing targeted interventions are essential for managing ADRD patient ED utilization.
