The modern hospital setting exposes our patients to a vast array of chemicals, some of which are therapeutic, others which can be particularly harmful. What are we doing to limit exposure to these harmful chemicals, for vulnerable patients and for those of us who work in hospitals every day? It may seem like an intrinsic goal for any healthcare venue, but it's a question that must be accounted for. Host Dr. Mark Nolan Hill explores the answer with Mr. Gary Cohen, co-executive director of Health Care Without Harm, an international campaign in support of environmentally responsible health care, and Dr. Ted Schettler, science director of the Science and Environmental Health Network, and science advisor to Health Care Without Harm.
