How Community Health Workers Dramatically Improve Healthcare

Popular in some countries and catching on in the U.S., community health workers fill gaping holes in care.

Hermon Girma is stirring bean stew over a wood-fed stove when she hears someone at the gate. She sends her 3-year-old son to slide open the piece of corrugated metal that separates her home and others from the cobblestone street in Kirkos, a neighborhood in Ethiopia’s burgeoning capital city, Addis Ababa.

Tigist Seyoum, a sturdy 35-year-old woman with a large black purse and cornrowed braids, leans down to kiss the boy’s cheek as she enters. The community health worker and the boy’s mother sit on a sofa in the Girmas’ home—two tidy, small rooms crammed with furniture. They chat about neighborhood gossip and the family’s health, including checking on birth control prescriptions.

Community health workers like Seyoum have helped Ethiopia reduce child mortality by two-thirds since 1990 and death from malaria, a common disease, by 55 percent. Since their deployment, contraception use among women—from longer-lasting injections to daily birth control pills—has doubled from 15 to almost 30 percent in six years.

More than 8,000 miles away in Williamson, West Virginia, 34-year-old Samantha Runyon visits about 15 homes a week to check blood sugar levels and teach people with diabetes how to deliver insulin injections.

The nurse, who works in the rural coal mining town where she grew up, is part of a team of four other “patient navigators” at a local nonprofit, the Diabetes Coalition. Her role is funded by a Duke University research grant aimed at curbing and treating diabetes.

“You’ve got more time with them,” she said. “In an office you’re on a set schedule, but here I don’t try to rush anyone.”

Across the world, countries have started to embrace community health workers as a means of reaching people who don’t always have regular access to care through clinics and hospitals.

Their titles vary—India has more than 800,000 “accredited social health activists” and Malawi employs 11,000 "health extension workers," but the impact seems to be universal. Not only do the workers treat and manage care, they also help curb health care costs by preventing complicated disease and emergency room visits.

Their success depends partly on local connections.

“The area where community health workers catch on is where they retain their community identity and their advocacy for their community and yet have a sharply defined role in their health care system,” said Columbia University’s Dr. Prabhjot Singh, chairman of the One Million Health Worker Campaign.

In Ethiopia, community health workers like Seyoum have become an integral part of the tiered national health care system put in place in 2004 to reach mostly rural families vulnerable to disease, hunger and isolation.  The country’s Ministry of Health employs 38,000 health extension workers—an all-women workforce of mostly high school graduates with one year of health training.

There are also about 38,000 community health workers in the U.S., according to the Department of Labor, but their role is more loosely defined. There is no uniform training or accreditation process, and their responsibilities vary by state. The Affordable Care Act includes a section recognizing the need for community health workers, but no decisions were made about their funding, said Dr. Nell Brownstein from the Centers for Disease Control and Prevention’s Division for Heart Disease.

Nevertheless, she said there is a big push from the both the health care system and states to build the workforce. Empirical research has continued to document their effectiveness—a 2009 study by the American Public Health Association, for example, found that community health workers’ intervention in the care of underserved men in Denver saved $2.28 for each dollar spent by redirecting people who would normally go to hospitals for care.

Florida and Texas have thousands of community health workers that help manage chronic disease and educate communities. Massachusetts and Minnesota have led the way in passing legislation to define their role in the health care system.

“It’s from the community up,” Brownstein said. “There’s a considerable amount of work being done.”
