this is a well written literature review.
A key question across domains is, “how are patients/health agents/consumers persuaded to acquire certain drugs and take them as directed?”
The introduction of “concordance” to the literature on medication compliance and adherence—“adherence” is the most neutral, non-ideological, term for patient behavior, in use at least since the mid 1990s.
The question that concordance theorists have really asked is not, “how do we treat patients’ health beliefs more respectfully?” but rather, “how do we persuade patients to follow the advice of their doctors?”
We can frame a rhetorical question across domains: how are people persuaded to take drugs?
Several authors have written even-handedly about concordance and make clear that cooperation between physicians and patients is likely to lead to better, and more appropriate, use of medications. Elwyn, Edwards, and Britten write, “Concordance describes the process whereby the patient and doctor reach an agreement on how a drug will be used, if at all. In this process doctors identify and understand patients’ views and explain the importance of treatment, while patients gain an understanding of the consequences of keeping (or not keeping) to treatment.” Ferner writes, “Usually…the patient, who has most to gain by success and the most to lose from harm, should decide whether to have treatment, and the prescriber should provide information on the risks and benefits to help make the decision.”
It is easy to agree that cooperative, better-informed, and realistically-prepared patients are more likely to adhere to recommended treatments than those who are resistant, ill- informed, and unprepared.
So, “concordance,” with its egalitarian rhetoric, not only portrays physicians and patients as equals but also portrays all patients as equals—while, in truth and in practice, patients are not all equally well-equipped for consensual decision-making, and, certainly, not all physicians believe that they are. When one exits the concordance literature to enter other literature about patients, what becomes clear is that the respect for patients that is invoked as the key resource of concordance is not always available to be tapped.
The more consumers are aware of a drug, the more they will request it; arguably, if they request it, then, being in agreement with their physician on its prescription, they are more likely to adhere to treatment.
