Budget impact analysis of medication reviews by junior pharmacists in polypharmacy patients: a hospital perspective.

We collected 271 medication reviews, including 1,689 medication recommendations.

Per-patient budget impact was negative for the intervention (€104 costs), but positive for medication recommendations (€46 savings), and preventable medication-related readmissions (€239 savings).

Opiates, beta receptor agonists, corticosteroids, urological drugs, and muscarine receptor antagonists generated 43% of medication recommendation savings.

Erythropoietic growth factors, SGLT2 inhibitors, etanercept, etravirine, and calcium/vitamin D formulations generated 70% of medication recommendation costs.
