Cardiac risk assessment after noncardiac surgery: a historical cohort study on guideline adherence at a Canadian quaternary care centre
Authors' conclusion
About half of the patients undergoing noncardiac surgery in our cohort underwent BNP screening as recommended by CCS guidelines; troponin and ECG acquisition adherence was even lower.
Study context
- Population
- Patients undergoing elective noncardiac surgery requiring overnight stay, McGill University Health Centre (quaternary care, Montreal), January 2018–December 2019
- Participants
- 3,623 patients
- Outcome
- Adherence to preoperative BNP measurement (Canadian Cardiovascular Society (CCS) 2016 guidelines)
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Preoperative BNP measurement adherence
BNP measurement adherence
52.4%
Observational data: associations, not effects.
Secondary outcomes
Postoperative troponin and electrocardiogram (ECG) acquisition adherence
- Troponin acquisition adherence
- 34.6%
- ECG acquisition adherence
- 30.5%
30-day outcomes, elevated vs non-elevated preoperative BNP
- MINS 20.2% vs 4.3%; P < 0.001
- MI 5.2% vs 0.5%; P < 0.001
- Mortality 2.5% vs 0.6%; P < 0.001
- Higher cardiac arrest and HF decompensation, to a lesser extent
30-day outcomes, elevated vs non-elevated postoperative troponin
- MI 20.7% vs 0.0%; P < 0.001
- Mortality 7.8% vs 0.6%; P < 0.001
- Higher cardiac arrest and HF decompensation, to a lesser extent
Physician follow-up
- Elevated BNP and troponin associated with higher physician follow-up rates
