We are very thankful to the three health care organizations and the group purchasing organization that made this study possible. Kyle Tafuri and pediatric nurses at Hackensack Meridian Health, Lauren Bulin and pediatric nurses at Dignity Health, and staff at a third health care organization and a group purchasing organization (both of which chose to remain anonymous) were all incredibly helpful in identifying products with the greatest use and potential for exposure in pediatric departments. Mary Ellen Leciejewski and Lauren Bulin of Dignity Health along with the staff at the anonymous organizations provided invaluable data, contacts, insights, guidance, and feedback, all of which were essential to the research and writing of the results. Alison Poor of Clean Production Action provided much needed support with references. Ellen Goldberg of Clean Production Action lent us her copy editing skills.

The question then is not, “Does the bed contain CoHCs?” The ques- tions should be, “What is the chemical footprint of this bed? How many CoHCs does a bed con- tain and what is the mass of CoHCs in this bed?” Suppliers of complex products such as beds should report the chemical footprint—the count and mass of CoHCs—of their products.

This research demonstrates how health care Specifically, this research demonstrates organizations can measure and reduce their Thow health care organizations can measure and reduce their chemical footprints, highlights the chemical footprints, highlights the need to perform need to perform additional research to fill data gaps, and identify products that do not contain additional research to fill data gaps, and identify chemicals of high concern (CoHCs), and clarifies products that do not contain chemicals of high the value of investing in systemic initiatives that will enable the rapid measurement and concern (CoHCs). reduction of chemical footprints.

Measure Chemical Footprint Many health care organizations have taken every day. This chemical footprinting research important steps to reducing CoHCs, such as demonstrates that hospitals can measure their BPA, phthalates, brominated flame retardants, chemical footprint, thereby creating a baseline to and PVC in the products they purchase and use which they can measure their progress.
