1We defined three insurance regulatory ‘regimes’ based on the combination of the two state insurance regulatory variables (R14, external review and R25, continuity of care.
Regime 1 (REG1) was defined as having both regulations in place (R14 = 1, R25 = 1). Regime 2 (REG2) was defined as having only one of these regulations in place (R14 = 1). Regime 3 (REG3) included all other states, which had neither regulation. See Table 7 for Regime Membership by States.
