Access to clear and concise medication information is essential to support safe and effective use of prescription drugs. Patient misunderstanding of medication information is a common reason for non-adherence to medication regimens and a leading cause of outpatient medication errors and adverse drug events in the U.S. Medication errors are the most common source of risk to patient safety, leading to poor health outcomes, hospitalizations, and deaths. Over half a million adverse drug events occur in the outpatient setting each year at a cost of approximately $1 billion annually.Nearly half of adults in the U.S. experience difficulty understanding and acting upon health information. Even individuals with high levels of general literacy may find medication information difficult to understand or use. The risk of misunderstanding medication information is compounded for patients with limited English proficiency who may not have access to this information in their own language.

There are three distinct questions associated with Simpson’s paradox. Why or in what sense is Simpson’s paradox a paradox? What is the proper analysis of the paradox? How one should proceed when confronted with a typical case of the paradox? We propose a “formal” answer to the first two questions which, among other things, includes deductive proofs for important theorems regarding Simpson’s paradox. Our account contrasts sharply with Pearl’s causal account of the first two questions. We argue that the “how to proceed question?” does not have a unique response, and that it depends on the context of the problem. We evaluate an objection to our account by comparing ours with Blyth’s account of the paradox. Our research on the paradox suggests that the “how to proceed question” needs to be divorced from what makes Simpson’s paradox “paradoxical.”

There are three distinct questions associated with Simpson's paradox, (i) Why or in what sense is Simpson's paradox a paradox? (ii) What is the proper analysis of the paradox? (iii) How one should proceed when confronted with a typical case of the paradox? We propose a "formar" answer to the first two questions which, among other things, includes deductive proofs for important theorems regarding Simpson's paradox. Our account contrasts sharply with Pearl's causal (and questionable) account of the first two questions. We argue that the "how to proceed question?" does not have a unique response, and that it depends on the context of the problem. We evaluate an objection to our account by comparing ours with Blyth's account of the paradox. Our research on the paradox suggests that the "how to proceed question" needs to be divorced from what makes Simpson's paradox "paradoxical."

Misuse or misunderstanding of medication information is a common and costly problem in the U.S. The risks of misunderstanding medication information are compounded for the large and growing population of individuals with limited English proficiency that often lacks access to this information in their own language. This paper examines practices related to translation of medication information in the European Union that may serve as a model for future U.S. policy efforts to improve the quality and availability of medication information for individuals with limited English proficiency
