Through the course of this book the reader is introduced to several personas and scenarios: Mr. B and Mrs. C living in their home setting with the onset of frailtiesFrailty, Agnes in residential LTC, Zahra seeking access and coordination through primary carePrimary care, and Francisco, a homelessHomeless and at risk older person finding himself in the interstitial spaceInterstitial space among conventional institutions of careCare. What all these personas demonstrate is that older adults encounter many challenges interfacing with a health care delivery systemHealth care delivery system that is poorly designed to address the unmet needs of older adults.  In addition, we emphasize that current health care delivery systems are not well coordinated or integrated which makes it particularly challenging for AgeTech to be effectively mobilized to help address the challenges of older persons.
