PEN-Plus is an integrated care delivery strategy focused on alleviating the noncommunicable disease (NCD) burden among the poorest children and young adults by increasing the accessibility and quality of chronic care services for severe NCDs—such as type 1 diabetes, rheumatic heart disease, and sickle cell disease—in the rural areas of low- and lower-middle-income countries, where more than 90 percent of the world’s poorest people live.
