Abstract: ADR is an important public health problem which reduces quality of care patients receive and increases cost to healthcare system. Little is known about the incidence and economic burden of ADR-related ED visits and subsequent hospitalizations in Canada. This study estimated the incidence and cost of ADR-related ED visits and subsequent hospitalizations for patients (>65 years) in Ontario, and explored patient, drug and system factors associated with severe ADRs. In a population-based retrospective cohort of Ontario older adults, 7222 (0.75%) of all ED visits were ADR-related, and among these patients 21.56% were hospitalized in 2007; In 2007, the total measured cost of ADR-related visits and subsequent hospitalizations amounted to $13.6 million with the cost being $333.47 and $7528.64 per person for ED visits and subsequent hospitalizations, respectively. Severe ADRs were associated with sex, age, comorbidity, multiple drugs, multiple pharmacies, newly prescribed drugs, recent ED visit, recent hospitalization and LTC residents.
