 Drug-related illness accounts for 5 to 23 of hospital admissions, and is now claimed to be the sixth leading cause of mortality. Older adults are at higher risk of adverse drug-related events, and medication-related fall injuries are the most common adverse event that could be potentially prevented. There are 1.2 million falls per year among Canadian elderly, at a cost of 2.4 billion in health care services, and substantial risk of loss of independence.
