Preventing hospital admissions by reviewing medication (PHARM) in primary care: an open controlled study in an elderly population

Abstract

A multicomponent pharmaceutical care intervention does not prevent medication-related hospital admissions. Whether this is true for such interventions in general is unknown, because the PHARM study was underpowered. The intervention may significantly reduce medication-related hospitalizations in patients with five or more comorbidities, but this is only based on a post hoc analysis and thus needs confirmation in large controlled trials.
