This review, published in official journal of the International Society of Pharmacovigilance, Drug Safety, is aimed at determining the overall incidence, severity and preventability of medication-related hospital admissions in Australia. In its conclusions, the authors estimate that 250,000 hospital admissions in Australia are medication-related, with an annual cost of AUD$1.4 billion to the healthcare system, and that two-thirds of medication-related hospital admissions are potentially preventable.
