How generalisable is evidence for health policy making across health systems, in particular evidence for prescription copayments? We addressed this question by studying two similar copayment policies in two health systems. We assessed the impact of each policy on adherence. These two similar copayment policies did not invoke similar responses in adherence to medications. Nuanced differences between the health systems and the patients within them may affect differences in impact of policies. Before applying evidence from one health system to another, critical questions about local applicability are key to maximising its’ utility.
