Methods Of Healthcare Delivery System

4.3K
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...

Preventive Healthcare Services

2.3K
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:

The World Health Organization (WHO) is a specialized agency of the United Nations based in Geneva. The WHO has many initiatives that center around health. Primarily, they lead global efforts to expand universal health coverage using science-based policies and programs. They are also responsible for shaping health research agendas and developing norms and standards.
The WHO provides expert team support, including funding, vaccines, testing, and treatment tools at the country level to fight...

Levels of Health Promotion and Illness Prevention

16.1K
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...

Healthcare Associated Infections II: Preventive Measures

5.0K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Primary Healthcare Services

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...

Area of Science:

  • Public Health
  • Epidemiology
  • Health Communication

Background:

  • Mass media's role in public health promotion is widely acknowledged but rarely quantified.
  • Measuring the impact of mass media on health outcomes in low-income settings remains a challenge.

Purpose of the Study:

  • To rigorously measure the number of lives saved by mass media interventions in a low-income country.
  • To assess the cost-effectiveness of large-scale media campaigns for public health.

Main Methods:

  • A cluster-randomised trial design is employed in Burkina Faso (ClinicalTrials.gov, NCT01517230).
  • The Lives Saved Tool is utilized to predict the impact of saturation-based media campaigns.

Main Results:

  • Saturation-based media campaigns are predicted to reduce child mortality by 10-20%.
  • The cost per disability-adjusted life-year is projected to be as low as existing health interventions.

Conclusions:

  • Mass media interventions show significant potential for reducing child mortality in low-income countries.
  • The study emphasizes the importance of media methodology in public health research and intervention.
