Our longest-running project, we have been screening children at Kids First Health Care in Commerce City Colorado for more than seven years. The six clinics include both community clinics and school-based health clinics (SBHCs). Efforts in primary care are supplemented by training and an obesity intervention led by the UCDenver School of Medicine and funded by the Colorado Health Foundation. Nurse practitioners at the clinics use the HeartSmartKids system to screen at well-child visits. The HeartPrint risk summary forms an important part of their protocol for delivering a brief 'aural obesity vaccine' that has shown a significant effect on improving the weight trajectory of overweight children. The system also helps practitioners refer qualifying patients to an obesity intervention that is delivered nearby.
