Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

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...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

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.

As Alzheimer's disease (AD) progresses, Medicare spending significantly increases. Early identification and intervention in preclinical AD are crucial for potential cost savings and improved patient outcomes.

Area of Science:

  • Gerontology
  • Neuroscience
  • Health Economics

Background:

  • Preclinical Alzheimer's disease (AD) progression and healthcare resource utilization (HRU) remain poorly understood.
  • Identifying early indicators of clinical progression in asymptomatic AD stages is critical.

Purpose of the Study:

  • To characterize AD progression and HRU in cognitively unimpaired individuals with elevated amyloid.
  • To evaluate the association between AD progression markers and healthcare utilization and costs.

Main Methods:

  • Linked Medicare claims data with outcomes from the Anti-Amyloid Treatment in Asymptomatic AD (A4) study for 246 participants.
  • Defined AD progression using Clinical Dementia Rating Scale-Global Score (CDR-GS) and Medicare data (cognitive impairment diagnosis, AD diagnosis, JEN Frailty Index [JFI] ≥ 6).
  • Analyzed associations between AD progression and diagnoses, encounters, and payments using logistic regression and linear regression.

Main Results:

  • 38% of participants showed CDR-GS progression; 46% had a cognitive impairment diagnosis, 24% an AD diagnosis, and 30% a JFI ≥ 6.
  • AD progression was associated with increased diagnoses of mood and anxiety disorders, falls, and higher inpatient utilization.
  • Medicare payments increased significantly with AD progression defined by cognitive impairment (45%), AD diagnosis (66%), and JFI ≥ 6 (103%).

Conclusions:

  • Medicare spending rises as Alzheimer's disease progresses from preclinical to symptomatic stages.
  • Further research is needed to explore cost savings associated with delaying progression to symptomatic AD.
