BackgroundTo determine the impact of preoperative Liver Dysfunction (LD) on outcomes after elective Coronary Artery Bypass Grafting (CABG) and Valvular surgery (VS).MethodsThe Nationwide Inpatient Sample (2002–2010) was queried to identify patients with LD who had elective CABG or VS utilizing ICD-9-CM diagnosis and procedure codes. These patients were matched with the similar patients without LD (controls) by propensity score matching. Chi-square and Wilcoxon rank sum tests were used for analysis.ResultsWe identified 1197 patients with LD (CABG = 755; VS = 442) who were matched to 2394 controls. LD significantly increased hospital mortality after both CABG (OR = 5.19; 95%CI = 2.93–9.20) and VS (OR = 7.49; 95%CI = 3.12–17.96). Overall rates of complications after CABG with LD were greater than in non-complicated cases (OR = 1.73; 95%CI = 1.46–2.05). Among them, there was an increase in bleeding (OR = 1.81;95%CI = 1.44–2.28), respiratory (OR = 2.33;95%CI = 1.86–2.93), renal (OR = 2.79;95%CI = 2.04–3.81), and infectious (OR = 2.93;95%CI = 2.14–4.01) complications. In general, the rates of complications after VS with LD were also greater than in non-complicated cases (OR = 2.77;95%CI = 2.13–3.60), specifically for bleeding (OR = 3.07;95%CI = 2.17–4.34), respiratory (OR = 3.57;95%CI = 2.51–5.07), renal (OR = 4.40;95%CI = 2.80–6.92), and infectious (OR = 4.63;95%CI = 2.85–7.51) complications. The development of LD significantly increased mean hospital length of stay (LOS) and total hospital charges after both CABG (from7.0 ± 4.0 to 9.2 ± 9.1 days and from $100,265 ± 87,107 to $117,756 ± 99,320, respectively; P < 0.0001 for both) and VS (from 7.9 ± 5.0 to 11.4 ± 9.9 days and from $134,306 ± 114,216 to $176,620 ± 147,049, respectively; P < 0.0001 for both).ConclusionsLD worsened the outcomes after cardiac surgery. It increased rates of complications, hospital mortality, length of stay and total hospital charges after both procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
