This table includes regression analysis of three waves of experimental data from a multiyear simulated patient study (2012, 2014, 2016); analyses were conducted by separated by insurance type of simulated patient. The linear regressions include county-clustered standard errors and state fixed effects.
All P values were determined within groups (ie, they do not represent significant differences between Medicaid and commercially insured simulated patients).
ACO, accountable care organization; ACPs, advanced care practitioners; CI, confidence interval; FQHC, Federally Qualified Health Center; HHI, Herfindahl-Hirschman Index; IHS, integrated health system; PCPs, primary care providers (MDs and DOs).
