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.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

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.

Vision impairment (VI) is linked to dementia risk. Early diagnosis and management of VI conditions like visual disturbances and lens disorders may help prevent dementia.

Area of Science:

  • Ophthalmology
  • Neurology
  • Gerontology

Background:

  • Untreated vision loss (VI) is a modifiable risk factor for late-life dementia.
  • The relationship between VI and cognitive decline in aging populations requires further investigation.

Purpose of the Study:

  • To analyze the association between vision comorbidities and dementia in large cohorts.
  • To understand the prevalence, patterns, and severity of VI in individuals with dementia.

Main Methods:

  • A case-control analysis of two dementia cohorts (UK Biobank and All of Us) using electronic health records.
  • International Classification of Disease-10 (ICD-10) codes were used to identify VI conditions.
  • Mann Whitney-U tests compared VI prevalence between dementia patients and controls, analyzing diagnostic block counts and age of first VI diagnosis.

Main Results:

  • 'Visual disturbances and blindness' were more prevalent in the dementia group (UKB, AoUS).
  • Earlier diagnoses of 'muscles, movement, accommodation and refraction' and 'disorders of the lens' VI were associated with dementia.
  • The time between first VI diagnosis and dementia onset was shorter for Alzheimer's disease than Vascular dementia.

Conclusions:

  • A significant association exists between specific VI diagnoses and dementia.
  • Early management of VI conditions is supported as a potential dementia prevention strategy.
