Summary
This observational study, published in the Journal of Surgical Research (2022), investigated whether pre-operative comorbidity burden, quantified using the Charlson Comorbidity Index, is associated with adverse outcomes following coronary artery bypass grafting. The authors appear to have found that higher comorbidity scores correlate with increased longer-term mortality and readmission rates, suggesting that comorbidity assessment may help identify high-risk patients requiring enhanced post-operative management.
Regional applicability
The findings may be relevant to UK cardiac surgery services when stratifying post-operative risk and planning discharge and follow-up care for CABG patients. However, applicability depends on whether UK cohorts have similar demographic and comorbidity distributions to the study population.
Key measures
Charlson Comorbidity Index score; mortality rates; hospital readmission rates; follow-up duration (longer-term)
Outcomes reported
The study examined associations between the Charlson Comorbidity Index (a measure of patient disease burden) and longer-term mortality and hospital readmission rates in patients undergoing coronary artery bypass grafting (CABG).
