“What if, instead of waiting for patients to overcome the many obstacles they face to come in for care, health systems were proactive, and went searching for patients door-to-door?” Ari Johnson, a co-founder of Muso and a physician at the University of California San Francisco, asks in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog. Johnson co-authored a study published this week in PLOS ONE that describes the success of a “partnership between the Malian Ministry of Health and two NGOs, Muso and Tostan.” The model “brings health care proactively into the home and removes fees that patients often cannot afford,” and “includes education, community organizing, and employment opportunities so that community members can overcome conditions of poverty that cause disease,” he writes (12/12).
