Rationale & Aim
Drug-related morbidity and mortality is an increasing problem in European healthcare systems. Multimorbidity, polypharmacy and old age are important risk factors for drug-related hospital admissions (DRA).  The reported incidence of DRAs in the elderly may be as high as 30% of all acute cases, [1,3] and about 50% of DRAs are likely to be preventable. [1,4] They are mainly related to prescribing problems and non-compliance with drug regimens. A significant proportion of healthcare costs are spent on unnecessary interventions and inappropriate medications.
The aim of the OPERAM trial is to assess whether pharmacotherapy optimisation leads to reduced drug related hospital admissions.
