Key result
CABG in the United States was associated with 82.5% higher in-hospital costs compared to Canada ($20,673 vs $10,373, P<.001), with no difference in in-hospital mortality.
Why the study?
Does coronary artery bypass graft surgery (CABG) in the United States compared to Canada result in different in-hospital outcomes and costs?
Observational (n=12,017)
Yes
Does coronary artery bypass graft surgery (CABG) in the United States compared to Canada result in different in-hospital outcomes and costs?
Effect estimate: 82.5% higher
Absolute Event Rate: 20673% vs 10373%
p-value: p=<.001
In-hospital costs for CABG are substantially higher in the United States compared to Canada, without yielding superior in-hospital clinical outcomes.
No takes yet. Share an insight, caveat, or question.
Higher US CABG costs without mortality benefit warrant cost scrutiny; leaves open system factors in observational comparisons.
Eisenberg et al. (2005) conducted an observational in Coronary artery disease requiring CABG (n=12,017). CABG in the United States vs. CABG in Canada was evaluated on In-hospital cost of treatment (82.5% higher, p=<.001). CABG in the United States was associated with 82.5% higher in-hospital costs compared to Canada ($20,673 vs $10,373, P<.001), with no difference in in-hospital mortality.
