Abstract

To determine if adjusted mortality, walking ability or return home differed after hip fracture surgery between Canada and the USA. Secondary analysis of the Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair (FOCUS) trial data. Data were collected from 47 American and Canadian hospitals. Overall, 2016 subjects with a hip fracture (USA = 1222 (60.6%); Canada = 794 (39.4%)) were randomized to a liberal or restrictive transfusion strategy. Subjects were 50 years and older, with cardiovascular disease and/or risk factors and hemoglobin <100 g/L within 3 days post-surgery. The average age was 82 years and 1527(76%) subjects were females. Demographics, health status and health services data were collected up to 60 days post-surgery and mortality to a median of 3 years post-surgery. Mortality, inability to walk and return home. US subjects had higher adjusted mortality than Canadians at 30 days (odds ratio = 1.78; 95% confidence interval: 1.09-2.90), 60 days (1.53; 1.02-2.29) and up to 3 years (hazard ratio = 1.25; 1.07-1.45). There were no differences in adjusted outcomes for walking ability or return home at 30 or 60 days post-surgery. Median hospital length of stay was longer (P < 0.0001) in Canada (9 days; interquartile range: 5-18 days) than the US (3 days; 2-5 days). US subjects (52.9%) were more likely than Canadians (16.8%) to be discharged to nursing homes for rehabilitation (P < 0.001). Adjusted survival favored Canadians post hip fracture while walking ability and return home were not different between countries. The reason(s) for mortality differences warrant further investigation.

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 May 2026.
All research outputs
#19,954,551
of 32,731,004 outputs
Outputs from International Journal for Quality in Health Care
#1,442
of 1,839 outputs
Outputs of similar age
#263,251
of 481,694 outputs
Outputs of similar age from International Journal for Quality in Health Care
#35
of 43 outputs
Altmetric has tracked 32,731,004 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,839 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.8. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 481,694 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
