On this edition of ST on Health, guest host John Schumann speaks with Tracy Davenport, a self-described "health care coordinator" --- basically, this means she's a freelance case manager who works to help patients and/or their families navigate today's ever-more-complicated medical system. It's often about being a good listener and asking lots of questions, says Davenport, who's had many years of experience as a registered nurse. She adds that she created her current health care coordinator position some 15 years ago, based largely on difficulties she had encountered in overseeing the medical care of her parents and children. Being a health care coordinator --- that is, being an on-demand, as-needed, and for-hire health care advocate --- means being available at all times, as one might expect; it also means being up-to-date and well-informed in terms of medical procedures, hospital protocol, and insurance practices. Asked whether she thinks our society might require more self-employed or individually-contracted health care coordinators in the coming years or decades, Davenport is immediately affirmative. "It comes down to two words," she says. "Baby Boomers."
