The document discusses the history and current state of Teaching Health Centers (THCs), which provide primary care medical residency training in community and rural health centers. Key points: - THCs were established in 2010 under the ACA to expand GME outside of hospitals. There are now 44 THC programs across 21 states. - THCs receive funding through 2015 from HRSA, but this funding will expire without reauthorization. Current residents may not complete training if funding lapses. - Legislation has been introduced to extend THC funding for 5 more years, but long-term support is still uncertain. The program shows promise for training more primary care physicians for underserved areas.
