One resolution adopted by the ACEP Council this year was particularly well-timed. As members in the southeastern states were faced with Hurricanes Helene and Milton during and after ACEP24, the Council approved a resolution for the College to advocate for the use of hospital tap water for wound irrigation.

Resolution 59 calls for health care professionals to:

• emphasize the importance of research and education within the emergency medicine community on the safety, efficacy, and potential cost savings of using hospital tap water for wound irrigation.
• urge U.S. policymakers and health care administrators to support initiatives, such as the use of hospital tap water for wound irrigation, that contribute to broader global efforts to enhance environmental sustainability and combat climate change in health care by decreasing the carbon footprint of emergency departments.

In the wake of Hurricane Helene, the Baxter International factory in North Carolina was flooded and shut down, preventing development and distribution of intravenous fluids around the country. The facility is one of the largest suppliers of IV fluids, the Food and Drug Administration has said. And at the time of this article going to press, Baxter still did not have a timeline for when the factory would be back up and running.

The American Society of Health-System Pharmacists (ASHP) issued a drug shortage alert for 0.9 percent sodium chloride irrigation on Oct. 4. ACEP and many hospitals nationwide were encouraging physicians to help conserve the supply, and establish protocols for reserving IV fluids for the most necessary use cases. Using tap water for wound irrigation was a common recommendation.

Resolution 59 pointed out that determining the efficacy of tap water compared to sterile saline in the United States would result in potential cost savings as 12.2 to 14.1 million people present to the ED for wound management. Assuming each one uses one bottle for irrigation, that would be 12.2 to 14.1 million bottles of plastic saved each year.

According to the background information provided with the Resolution, endorsing the use of tap water in the United States, instead of sterile saline solutions, can contribute to significant cost savings, reduce the carbon footprint of emergency departments, and advance efforts to mitigate climate change, all while maintaining high standards of patient care.

Several studies have endeavored to compare the use of tap water versus normal saline for wound cleansing. A 2021 Cochrane Review by Fernandez, et al., included 13 randomized controlled trials that compared wound cleansing with tap water, distilled water, cooled boiled water, or saline with each other or with no cleansing on wound infection, wound healing, reduction in wound size, rate of wound healing, costs, pain, and patient satisfaction.
