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...

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.

Frontotemporal dementia (FTD) patients often lack specialist care and brain imaging, with primary care clinicians identifying most cases. This highlights a need for improved diagnostic support and referral pathways for FTD.

Area of Science:

  • Neurology
  • Geriatrics
  • Psychiatry

Background:

  • Frontotemporal dementia (FTD) is a rare, young-onset dementia characterized by behavioral and language deficits.
  • No therapeutics are currently approved for FTD, though trials are underway for specific genetic mutations (e.g., GRN).
  • Understanding diagnostic pathways and imaging use is crucial for improving FTD case identification and access to future treatments.

Purpose of the Study:

  • To characterize FTD patients, focusing on specialist consultations, comorbidities, brain imaging, and medications.
  • To analyze diagnostic and referral patterns within a large, real-world data (RWD) cohort.
  • To identify opportunities for improving FTD diagnosis and patient access to care.

Main Methods:

  • Retrospective, observational RWD cohort study using electronic health records and insurance claims in the USA.
  • Analysis of over 300 million patient lives, identifying an FTD cohort based on specific diagnostic codes (G31.0, G31.09).
  • Characterization of patient demographics, specialist consultations (neurology, mental health), comorbid diagnoses, brain imaging (MRI, CT), and concomitant medications within a defined timeframe around diagnosis.

Main Results:

  • The FTD cohort (41,353 patients, mean age 73) showed limited specialist involvement: 21% neurologist, 12% mental health (MH) professional consultations.
  • FTD diagnoses were primarily linked to primary care records (17% neurologist, 3% MH professional association).
  • High comorbidity rates included psychiatric disorders (82%) and non-FTD dementias (99%); brain imaging was infrequent (40% had either MRI or CT).

Conclusions:

  • Challenges in accurate FTD diagnosis are indicated by low specialist consultation rates, limited brain imaging, and frequent non-FTD dementia diagnoses.
  • The high prevalence of psychiatric disorders without MH consultation was unexpected.
  • Primary care clinicians identify most FTD patients, suggesting a need for targeted educational and policy initiatives to support appropriate referrals and raise disease awareness.
