BOSTON -- Millions of Americans are struggling to care for elderly parents, a task that can be especially stressful if they live far apart and the parent wants to continue living at home.

Dovetail, a Massachusetts-based company, is combining medicine and technology to keep the elderly at home in an affordable, safe way.

NewsCenter 5’s Heather Unruh reported Friday that Evelyn Lazurus has been living in her Lynn home for 22 years, and wants to stay there as long as she can

"I'll be 81 in September. As long as you’re able to, and have the mobility, and have people who care about you ... you can fight the world," she said.

Evie relies on Dovetail’s services. "In the morning I come downstairs, I take my blood pressure, take my blood count, I take my weight, and if those are off, right away Dovetail calls me."

Miles away in Needham, Evie's very own health care team is reviewing her medical information in real-time to detect potentially life-threatening problems, using innovative technology.

Dr Richard Dupee, a geriatric doctor and Dovetail's medical director, said, "Change in blood pressure, change in blood sugar ... that information is going to get to me right away on my desk, so that I can deal with it immediately and keep these patients out of the hospital."

With nursing home and assisted-living care so expensive, Dovetail is one of a growing number of similar, more affordable services like it. Depending on the services provided, it costs between $15 and $25 per day.

Geriatric Specialist Dr. Richard Dupee said the greatest benefit is the medication management. "About 20-percent of our patients don't take their medications properly."

Evie is confident she'll never have a medication mix-up. Dovetail got her a pharmacy that packages her pills, and keeps her physicians up to date on all her medications.

"I don't have to count them, I don't have to know what they are," she said. "All I have to do is cut the yellow envelope."

Stever Aubrey, CEO of Dovetail, said, "The most important thing though is not necessarily the devices, it's the relationship we have with the individuals."

"I know they're concerned about me, they're looking after me," said Lazurus.
