What type of approach does primary care use to promote overall health equity?

The correct choice emphasizes that primary care employs a preventative and accessible healthcare service model, which is essential for promoting overall health equity. This approach focuses on preventing illnesses before they occur and ensuring that healthcare services are readily available to all individuals, regardless of their socio-economic status, geographic location, or other factors that might create disparities in health.

By prioritizing prevention, primary care can address the root causes of health issues and lead to better health outcomes for the community as a whole. Accessibility ensures that everyone can receive necessary healthcare services, which is crucial in reducing health inequities that often arise when certain groups face barriers to receiving medical attention.

In contrast, specialized care for chronic diseases tends to focus only on specific health issues, potentially neglecting broader systemic factors that affect overall health. A multidisciplinary approach can be effective but may not solely promote health equity without emphasizing preventative care and accessibility. A reactive approach that only addresses illnesses would fail to prevent health issues from developing in the first place, exacerbating inequities in healthcare access and outcomes.
