Preventive medicine can be categorized as primary, secondary, or tertiary. Primary prevention aims to remove or reduce disease risk factors and is the principle activity of the Health Guardian. Secondary prevention techniques promote early detection of disease or precursor states normally beginning with a holistic health assessment. Tertiary prevention measures are aimed at limiting the impact of established chronic disease through strategic lifestyle changes.

   The steps of a Evidence Based Practice, which the Health Guardian masters, centers around cultivating a spirit of inquiry. They must ask compelling and provoking clinical questions. The objective is the finding and identification of relevant evidence used to answer these clinical questions. The Health Guardian must critically appraise the gathered evidence, become an expert in the art of moving evidence to a sustainable effort of change. Many times, success revolves around the ability to create and sustain a culture and environment for long-term evidence-based caregiving.
