title: Primary care shortages: strengthening this sector is urgently needed, now and in preparation for healthcare reform.
abstract: BACKGROUND
  The United States currently faces great challenges in primary care, particularly when the Patient Protection and Affordable Care Act (ACA) greatly expands the health insurance market.
  
  
  OBJECTIVE
  To (1) discuss key areas where primary care needs to be strengthened, including advanced models of physician reimbursement, chronic disease management, and improved patient adherence to medications, and (2) to review initiatives applying evidence-based medicine (EBM) where positive changes have in fact occurred.
  
  
  CONCLUSIONS
  This article discusses initiatives that have implemented EBM as their model for change and presents interviews with primary care experts to support the growing need for change in primary care. To improve the quality of care and reduce costs, more needs to be done, particularly by fostering the number of primary care physicians (PCPs) and other healthcare professionals in PCP offices, as well as adjusting payment methods that much more strongly support and reward the primary care and the patient-centered medical home (PCMH) models. An additional area where substantial improvements are needed involves inner-city, rural, and other underserved populations. Provider- and managed care-driven changes are taking place, but much more needs to be done, particularly as a result of the ACA-associated health insurance enrollment expansion. Innovation in payment for PCPs and PCMHs (and corresponding changes in care delivery and improvements in clinically significant outcomes) will be key factors toward the successful implementation of ACA changes. In addition, several examples are discussed, in which the flexibility of managed care and its results-driven orientation are crucial factors for success. Future initiatives that will likely be more challenging and will require significant government funding include the US underserved populations and incentives to encourage medical school students and residents to choose primary care as a specialty.
  
  
  CONCLUSIONS
  More innovation, particularly related to realignment of financial incentives to strengthen primary care, is needed to meet America's growing healthcare quality and cost challenges.
