Patient-Centered Prescription Model to improve therapeutic adherence in patients with multimorbidity

To date, interventions to improve medication adherence in patients with multimorbidity have shown modest and inconsistent efficacy among  available studies. Thereby, we should define new approaches aimed at improving medication adherence tailored to effective prescribing, with a multidisciplinary approach and patient-centered.In this regard, the Patient-Centered Prescription Model has shown its usefulness on improving appropriateness of drug treatments in patients with clinical complexity. For that, this strategy addresses the following four steps: 1) Patient-Centered assessment; 2) Diagnosis-Centered assessment; 3) Medication-Centered assessment; and 4) Therapeutic Plan.We propose through a clinical case an adaptation of the Patient-Centered Prescription Model to enhance both appropriateness and medication adherence in patients with multimorbidity. To this end, we have  included on its first step the Spanish version of a cross-culturally adapted scale  for the multidimensional assessment of medication adherence. Furthermore, we suggest a set of interventions to be applied in the three remaining steps of  the model. These interventions were firstly identified by an overview of systematic reviews and then selected by a panel of experts based on Delphi methodology.All of these elements have been considered appropriate in patients with multimorbidity according to three criteria: strength of their supporting  evidence, usefulness in the target population and feasibility of implementation in clinical practice.The proposed approach intends to lay the foundations for an innovative way in  tackling medication adherence in patients with multimorbidity.
