A Healthy Summer with PAI

A few months ago, we share the news that PAI would be used by the MedStar Health Research Institute for a study on daily interactions with avatars for patients suffering from chronic heart failure.

Meet Tara, the new Healthcare Assistant PAI being used in a research study by Medstar Health Research Institute

Through the combined efforts of the ObEN and Medstar teams, patient recruitment for the study is well underway, and soon PAI Healthcare Assistant Tara will be able to have hands on interactions with patients, analyzing their health information and engaging with them daily to help support their recovery.

ObEN CEO Nikhil Jain recently recorded an interview with eHealth podcast regarding the study, which will be available soon to listeners worldwide. So stay tuned, we will be sharing the interview and study developments throughout this summer and fall!

See you in the next issue of PAI Updates!
