Global and Patient Services

For more than 20 years, Johns Hopkins Medicine International has developed collaborative platforms for improving health care delivery around the world. Read more about how we help leading hospitals, health providers, governments and educational institutions increase and enhance services locally so patients can receive quality care as close to home as possible. In complex instances when patients are unable to receive the care they need at home, Johns Hopkins Medicine International has one of the most experienced programs in the United States, designed for delivering the highest quality care for traveling patients. We are with our patients and families through every step of their visit to Johns Hopkins, so they can focus on their health.
