RESISTANCE CAN BE FATAL: As bacteria continue to develop resistance to commonly used antibiotics, local hospital systems are focusing on implementing best practices to ensure effective stewardship of existing antibiotics.

Antibiotic resistance has become a serious problem, causing infections that can’t be treated and thousands deaths every year in the U.S. as a result. Many hospitals, including several local ones, have created antibiotic stewardship programs, which develop strategies for the appropriate use of antibiotics while decreasing the chance of bacteria becoming resistant to them.
