About This Program

Within the Massachusetts General Hospital Emergency Department, pharmacists are a vital part of the clinical treatment team. Pharmacists provide 24/7, in-person coverage of the department to meet the needs of all patients. Members of the team are experts in various areas, including stroke, sepsis, pain and palliative care, toxicology, geriatrics, infectious diseases, resuscitation, disaster response, pediatrics and anticoagulation, and serve on numerous committees throughout the hospital. In addition to providing care for critically ill patients, pharmacists serve an integral role in facilitating treatment of patients with opioid use disorder in conjunction with the Mass General Bridge Clinic. To assist this vulnerable population with obtaining, understanding and using their medications, staff counsel patients on intranasal naloxone and buprenorphine-naloxone, as well as providing them with supplies of each, as appropriate.

We also support the Mass General Pharmacy’s mission to enrich the lives of the diverse community we serve by being accountable for optimal outcomes through exceptional pharmacy practice, innovation, education and interdisciplinary collaboration. To further the practice of pharmacy in the ED, we have an ASHP-accredited PGY-2 Emergency Medicine pharmacy residency which was instituted in 2017. Mass General pharmacists hold faculty appointments at Harvard Medical School, Northeastern University School of Pharmacy and Massachusetts College of Pharmacy and Health Sciences.
