iSIMPATHY: a multinational pre-post non-randomised intervention study transforming medication review

Taking multiple medicines can be appropriate but has the potential to be problematic. The Implementing Stimulating Innovation in the Management of Polypharmacy and Adherence THrough the Years (iSIMPATHY) project used the 7-Steps person-centred approach for medication reviews, supporting patients and clinicians to define and achieve realistic goals for drug treatment, and helping enable patients to lead healthy and active lives.

To assess the impact of pharmacist-led comprehensive person-centred medication reviews using the 7-Steps methodology.

iSIMPATHY sought to transform the approach to optimisation of medicinces through the delivery of person-centred medication reviews for people taking multiple medicines in primary care, hospital and outpatient clinics. The reviews were conducted by embedding a single approach for polypharmacy management, building on key recommendations from SIMPATHY.

Interventions made were graded, with 82% being classified as clinically significant and 4% potentially preventing major organ failure, adverse drug reactions or incidents of similar clinical importance. The average number of medications reduced from 12 to 11, with 92% of the reviews resulting in more appropriate medication use, thereby decreasing the likelihood of medication-related harm. Inappropriate medicines were stopped, reduced or altered to improve appropriateness. There were significant healthcare resource utilisation benefits as indicated by a positive return on investment for both medication and healthcare costs with a quality-adjusted life year gain of 7.4 per 100 patients.

Pharmacist-led, person-centred medication review using the 7-Steps approach was delivered across jurisdictions and healthcare settings, with positive impacts on the number and appropriateness of medicines, clinical interventions and cost savings outweighing expenditure on the service. The approach is scalable by means of the tools and resources developed over the duration of the project.
