Summary
Retrofitting older homes with insulation and better heating significantly improves occupant health and energy efficiency in New Zealand. These housing upgrades are cost-effective solutions for enhancing well-being and reducing illness.
Area of Science:
- Environmental Health
- Public Health
- Building Science
Background:
- Older homes in New Zealand often lack adequate insulation and heating, making them unsuitable for the local climate.
- This mismatch can negatively impact occupant health and well-being.
Purpose of the Study:
- To identify cost-effective methods for improving older homes.
- To enhance occupant health through better housing characteristics.
Main Methods:
- Two community randomized trials focused on retrofitted insulation and improved heating.
- Ongoing studies include electricity vouchers and housing hazard remediation.
Main Results:
- Insulating 1,350 houses improved occupant health, well-being, and energy efficiency.
- In insulated homes with children diagnosed with asthma, improved heating halved indoor nitrogen dioxide (NO2) levels.
- Children experienced fewer asthma symptoms, less poor health, and reduced school absenteeism.
Conclusions:
- Improving energy efficiency in older housing yields significant health and energy savings.
- Multidisciplinary housing interventions provide evidence for sustainable housing policies that promote health.

01:30Community Based Intervention
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

01:29Documentation in Long-Term and Home Healthcare Setting
Documentation in long-term care facilities and home healthcare settings is crucial for ensuring continuous, coordinated, and comprehensive care for patients. Each setting has its specific documentation processes and tools:

01:30Primary 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.

01:26Methods Of Healthcare Delivery System
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 limited...

01:26Levels of Health Promotion and Illness Prevention
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.

01:18Models of Health Promotion and Illness Prevention II
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
