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...

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

Dementia diagnosis in Brazil shows significant gaps, with most centers relying on clinical and cognitive tests rather than advanced biomarkers. Improving diagnostic practices and access to tools is crucial for better dementia care.

Area of Science:

  • Neurology
  • Public Health
  • Geriatrics

Background:

  • Effective dementia management relies on early diagnosis, yet low- and middle-income countries like Brazil face resource disparities.
  • Specialized dementia care centers in Brazil exhibit significant heterogeneity in diagnostic resources and practices.

Purpose of the Study:

  • To assess diagnostic methods and clinical practice tools in specialized dementia care centers across Brazil.
  • To identify disparities in dementia diagnosis resources and practices within Brazil.

Main Methods:

  • An online survey was distributed to neurologists in specialized dementia centers across Brazil.
  • Data collected included infrastructure, cognitive tests, biomarker availability (CSF and imaging), and sociodemographic data.
  • Responses were gathered in July 2024 from neurologists affiliated with the Brazilian Academy of Neurology.

Main Results:

  • Twenty-four centers across 10 states participated, with 87% linked to the Public Health System.
  • Clinical and cognitive assessments are widely used (e.g., Mini-Mental State Examination, Montreal Cognitive Assessment), but advanced biomarkers (CSF, PET scans) and genetic testing are scarce.
  • Significant gaps exist in data collection, with ethnicity and socioeconomic status often omitted, and limited use of dementia staging tools.

Conclusions:

  • Dementia diagnosis in Brazil is characterized by heterogeneity and a reliance on traditional methods over biomarker-based approaches.
  • Standardizing data collection and expanding access to advanced diagnostic tools are essential for improving dementia care.
  • Harmonizing diagnostic practices is necessary to align with current criteria emphasizing biomarkers for accurate dementia diagnosis.
