Lindsey Clark Posted almost 4 years ago "WHY is the patient the most under-used resource in healthcare?? How did that happen?" (Follow-up to LIVE TED Conversation July 27) I think levels of efficacy also affect how engaged patients are. If patients have high levels of efficacy (have the tools and feel they are empowered) then they are more likely to be engaged in their health and take charge of their health. Those who lack resources (such as insurance or medical data) may find it more difficult to get engaged in their health.
