Adverse drug reactions in seniors
The Canadian Institute for Health Information (CIHI) reports that 1 in 200 seniors was hospitalized because of an adverse drug reaction between 2010 and 2011, compared with 1 in 1000 of all other Canadians.
The number of seniors hospitalized due to an adverse drug reaction has increased by an average of 3% a year between 2006–2007 and 2010–2011, and accounted for about 3% of all seniors’ hospitalizations over the period.
CIHI says the real rate of adverse drug reaction–related hospitalizations is likely higher since the issue is known to be underreported in administrative data.
Blood thinners, often used to prevent heart attack and stroke, were the drug class most commonly associated with hospitalizations related to adverse drug reactions among seniors (12.6%). This was followed by chemotherapy drugs (12.1%) and opioids (7.4%).

Above is the information needed to cite this article in your paper or presentation. The International Committee
of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally
accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.
About the ICMJE and citation styles
The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.
An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.
BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:
- Only the first three authors are listed, followed by "et al."
- There is no period after the journal name.
- Page numbers are not abbreviated.
