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.

The 2020 telehealth expansion may have increased Alzheimer's disease and related dementias (ADRD) diagnoses in areas with broadband access. This suggests telehealth can improve ADRD diagnosis rates for Medicare beneficiaries.

Area of Science:

  • Gerontology
  • Public Health
  • Health Services Research

Background:

  • Population aging increases the risk of underdiagnosed Alzheimer's disease and related dementias (ADRD).
  • Limited diagnostic service availability contributes to ADRD underdiagnosis.
  • Telehealth expansion, dependent on broadband access, offers potential to improve ADRD diagnostic service accessibility.

Purpose of the Study:

  • To investigate the effect of the 2020 Centers for Medicare and Medicaid Services (CMS) telehealth expansion on county-level ADRD diagnosis prevalence.
  • To examine this effect among fee-for-service (FFS) beneficiaries in relation to broadband availability.

Main Methods:

  • A county-level ecologic difference-in-difference (DID) design was used, comparing pre-expansion (2016-2017) and post-expansion (2021-2022) periods.
  • ADRD prevalence was estimated using CMS data, and broadband presence was defined by Federal Communications Commission standards.
  • Negative binomial regression models assessed the impact of the telehealth expansion on ADRD prevalence in broadband-accessible counties, with rurality as a potential modifier.

Main Results:

  • ADRD prevalence decreased from 11.06% to 7.15% overall between the periods.
  • Broadband availability increased from 70.35% to 91.96% of counties.
  • Post-expansion, counties with broadband showed a 2.48% higher ADRD prevalence compared to those without, relative to the pre-expansion period.

Conclusions:

  • Preliminary findings suggest the CMS telehealth expansion may positively impact ADRD diagnostic prevalence in areas with broadband.
  • Improvements in ADRD detection might be linked to telehealth access in broadband-equipped counties.
  • The overall decrease in ADRD prevalence warrants further investigation, potentially related to the COVID-19 pandemic.
