title: National findings regarding health IT use and participation in health care delivery reform programs among office-based physicians.
abstract: Our objective was to characterize physicians' participation in delivery and payment reform programs over time and describe how participants in these programs were using health information technology (IT) to coordinate care, engage patients, manage patient populations, and improve quality.
  
  
  
  A nationally representative cohort of physicians was surveyed in 2012 (unweighted N = 2567) and 2013 (unweighted N = 2399). Regression analyses used those survey responses to identify associations between health IT use and participation in and attrition from patient-centered medical homes (PCMHs), accountable care organizations (ACOs), and pay-for-performance programs (P4Ps).
  
  
  
  In 2013, 45% of physicians participated in PCMHs, ACOs, or P4Ps. While participation in each program increased (P < .05) between 2012 and 2013, program attrition ranged from 31-40%. Health IT use was associated with greater program participation (RR = 1.07-1.16). PCMH, ACO, and P4P participants were more likely than nonparticipants to perform quality improvement and patient engagement activities electronically (RR = 1.09-1.14); only ACO participants were more likely to share information electronically (RR = 1.07-1.09).
  
  
  
  Participation in delivery and payment reform programs increased between 2012 and 2013. Participating physicians were more likely to use health IT. There was significant attrition from and switching between PCMHs, ACOs, and P4Ps.
  
  
  
  This work provides the basis for understanding physician participation in and attrition from delivery and payment reform programs, as well as how health IT was used to support those programs. Understanding health IT use by program participants may help to identify factors enabling a smooth transition to alternative payment models.
