Heart transplantation is the definitive management for select patients with end-stage heart failure in BC. Due to an ongoing organ donor shortage, organs are sometimes allocated from distant locales. These organs may be perceived as less desirable due to donor risk factors and ischemic times. We compared survival after heart transplantation in BC between 1 December 1988 and 21 October 2014 stratified by donors originating from BC, other Canadian provinces, and the US.
Among 382 patients, 297 (77.7%) recipients and 238 (62.3%) donors were male. The median recipient age was 55 years and the median donor age was 33 years. Median ischemic time was lower in BC donors (168 IQR [107.5, 228.0] min) compared with Canada (243 IQR [204.5, 291.0] min) and the US (244 IQR [217.3, 278.8] min) (P < 0.01). Overall 10-year survival was 62.1%, 95% CI [56.3, 67.4]. There was no difference in 10-year survival when comparing donors from BC, Canada, and the US (Figure) despite significantly different ischemic times. Multivariate Cox regression analysis found no relationship between origin and mortality after controlling for recipient age, donor age, and cold ischemic time.
Among patients undergoing orthotopic heart transplantation in BC, carefully selected distant-donor organs result in similar long-term outcomes despite increased ischemic times. Incorporating these findings into organ allocation protocols may extend criteria for donor selection, thereby increasing the donor pool and organ availability.

of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally
accepted citation style for scientific papers:

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.
