Green Health Care

Hospitals are becoming healthier places due to new efforts to protect the environment.

green hospitals are more common in healthcare"Given that our mission is both to keep people healthy and to help them heal when they're unhealthy, it would be a complete contradiction for us to contribute to poor health—whether of employees, patients, or the community," says Barbara Sattler, director of the University of Maryland School of Nursing's Environmental Health Education Center.

"We want our healthcare institutions to be healing places."

In 2005, Sattler founded Maryland Hospitals for a Healthy Environment (MD H2E). Today, the organization boasts a membership comprising three-quarters of the hospitals in the state. Their efforts include recycling and composting, reduced reliance on toxic chemicals, and environmentally preferable purchasing policies. "We're seeing the hospitals begin to adopt an environmental ethic," Sattler says, "so it's part of the fabric of the decisions they're making."

That doesn't make it easy. "An institution with 7,000 employees and 800 patients on any given day, it's a huge operation," says Denise Choiniere, the sustainability manager at the University of Maryland Medical Center. In 2006, as a cardiac-care nurse in intensive care, Choiniere launched a recycling program that now diverts nearly 100,000 batteries annually from incineration. Other initiatives include a 50 percent reduction in regulated medical waste, high-efficiency vacuum pumps to reduce water consumption by 5 million gallons annually, and a program to divert discarded drugs from municipal wastewater treatment facilities that often can't remove them.

Louise Mitchell, MD H2E's sustainable foods program manager, promotes the Healthy Foods in Health Care Pledge by connecting hospital food-service directors and chefs with local farmers to increase their purchase of local, sustainable foods. She also provides technical support for other healthy food initiatives. One outcome of this support is that 17 health-care facilities statewide now host farmers' markets or farm stands on their campuses. This fall, she hosted a training program for kitchen staff interested in purchasing and preparing sustainably produced meat and poultry from small, local farms. "Hospitals have shifted toward having more food delivered that's already prechopped or precooked," says Mitchell. "They have the kitchens and the knives to prepare fresh foods, but they don't necessarily have the labor or the ovens."

The Maryland Pesticide Network and project partner Beyond Pesticides collaborate with MD H2E to promote the reduction or elimination of pesticides from hospitals and elder-care facilities. They advocate replacing conventional pest management that relies on chemical pest controls—many of which are linked to cancer, Parkinson's, autoimmune disorders, and reproductive dysfunction—with non-chemical pest prevention, using the least toxic pesticides only as a last resort. "Pests can carry disease, so pest management is really important," says psychotherapist and MPN executive director Ruth Berlin. "But so is protecting people from unnecessary exposure to hazardous pesticides."

Bringing greener solutions to health care demands a passion for questioning the status quo. Sattler compares it to weighing treatment options for a headache: Sure, you could take morphine to knock back the pain, but most of the time Tylenol will do the trick.

"The morphine is overkill," Sattler says.

"We began to look for the Tylenol—the least toxic but still effective option—throughout the industry."
