A PHR typically comprises of demographic info, physical exam and medical history, clinical and hospital discharge notes, diagnostics test results and medications.
From the lit review we identified some PHR attributes that are related to medication adherence. PHRs have other attributes for example bill viewing and payment, drug to drug interaction systems, immunization records etc. We do not argue that these attributes do not help with medication adherence, we are simply stating the fact that we did not find evidence in the literature that they do so. The included attributes as well as others that we might omit i.e. bill viewing, assist patients with the general purpose of PHR which is to decrease care cost and make the management of diseases easier.
