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...

Area of Science:

  • Gerontology
  • Public Health
  • Neuroscience

Background:

  • The Canadian Therapeutics Platform for Multidomain Interventions to Prevent Dementia (CAN-THUMBS UP) developed the Brain Health PRO (BHPro) online program.
  • BHPro aims to address modifiable lifestyle risk factors for dementia remotely and cost-effectively.
  • This study reports on the inception cohort's risk factor profiles and longitudinal outcomes from the BHPro intervention.

Purpose of the Study:

  • To evaluate the impact of the BHPro online intervention on modifiable dementia risk factors.
  • To assess changes in a composite lifestyle risk score and individual risk factors over 12 months.
  • To explore the potential of a web-based program in managing dementia risk.

Main Methods:

  • A 12-month prospective, multi-center, longitudinal study involving 353 Canadian participants.
  • Participants included older adults with or without mild cognitive impairment (MCI) and at least one dementia risk factor.
  • The intervention consisted of 181 online chapters on dementia risk factors, with outcomes assessed at 6 and 12 months.

Main Results:

  • A significant positive change in the composite lifestyle risk score was observed at 6 months (standardized change = 0.162, p < 0.001) and 12 months (standardized change = 0.167, p < 0.001).
  • Statistically significant improvements were noted in individual risk factors including physical activity, nutrition, cognitive engagement, and sleep at both 6 and 12 months.
  • The intention-to-treat sample (N=353) with a mean age of 69.7 years showed these improvements.

Conclusions:

  • The inexpensive, web-based BHPro intervention successfully improved key modifiable risk factors for Alzheimer's disease.
  • Improvements in lifestyle risk factors were evident after 6 and 12 months of program participation.
  • Future research will focus on larger, diverse populations and the direct impact of lifestyle improvements on dementia risk reduction.
