The Centers for Medicare and Medicaid Services' (CMS) State Innovation Models (SIMs) initiative funded 17 states to implement health care payment and delivery system reforms to improve health system performance. Whether SIM improved health information technology (HIT) and care management capabilities of physician practices, however, remains unclear. National surveys of physician practices (N = 2,722) from 2012 to 2013 and 2017 to 2018 were linked. Multivariable regression estimated differential adoption of 10 HIT functions and chronic care management processes (CMPs) based on SIM award status (SIM Round 1, SIM Round 2, or non-SIM). HIT and CMP capabilities improved equally for practices in SIM Round 1 (5.3 vs. 6.8 capabilities, p < .001), SIM Round 2 (4.7 vs. 7.0 capabilities, p < .001), and non-SIM (4.2 vs. 6.3 capabilities, p < .001) states. The CMS SIM Initiative did not accelerate the adoption of ten foundational physician practice capabilities beyond national trends.
