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...

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...

Area of Science:

  • Neurology
  • Cardiovascular Medicine
  • Public Health

Background:

  • Carotid Atherosclerosis (CAS) is a risk factor for stroke.
  • Cognitive impairment affects a significant portion of the aging population.
  • Understanding the link between CAS and cognitive impairment is crucial for stroke prevention strategies.

Purpose of the Study:

  • To investigate the association between Carotid Atherosclerosis (CAS) and cognitive impairment.
  • To analyze this relationship in a high-risk stroke population aged 40 and above in rural Xi'an.

Main Methods:

  • A cohort of 451 individuals from a stroke screening project in Xi'an were analyzed.
  • Carotid Atherosclerosis (CAS) was assessed using Color Doppler ultrasound.
  • Cognitive function was evaluated using the Mini-Mental State Examination (MMSE).

Main Results:

  • The study included 451 participants, with 72.9% having CAS and 12.6% exhibiting cognitive impairment.
  • While the prevalence of cognitive impairment was higher in the CAS group (14.6% vs. 7.4%), this association was not statistically significant in multivariate analysis.
  • Cognitive impairment was significantly correlated with stroke history (OR=11.924) and diabetes mellitus (OR=1.883).

Conclusions:

  • No significant association was found between Carotid Atherosclerosis (CAS) and cognitive impairment in this high-risk stroke population.
  • Stroke history and diabetes mellitus were identified as significant risk factors for cognitive impairment in this cohort.
