Background There is an ongoing debate on the benefits and risks of off-pump coronary artery bypass grafting (CABG) surgery. The fate of patients who start with their procedure being an off-pump one and then have to undergo conversion to an on-pump procedure is debated with regard to in-hospital mortality and unknown with regard to long-term survival. We investigated the in-hospital mortality and long-term survival of patients who underwent conversion from off- to on-pump surgery. Methods We performed a multivariate and propensity analysis on in-hospital mortality and long-term survival of postisolated CABG patients in a single institution having 15,704 patients of which 5,353 who underwent off-pump CABG were analyzed. Results In-hospital mortality was 2.15% for the study cohort, and 73 (1.4%) off-pump cases were converted. Univariate analysis demonstrated that patients undergoing conversion had a significantly increased in-hospital mortality (p < 0.001) and reduced long-term survival (p = 0.002). Logistic regression (receiver operating curve 0.77, Hosmer-Lemeshow test 0.46) and Cox analysis demonstrated that in-hospital mortality and long-term survival were not significantly affected by conversion. Propensity analysis (one:many match) demonstrated that in-hospital mortality was not significantly affected (p = 0.7), and long-term survival - univariate, and multivariate were also not significantly reduced in patients undergoing conversion. Conclusion Conversion from off- to on-pump by a team of surgeons and anesthetists who are dedicated off-pump specialists does not have an impact on in-hospital mortality or long-term survival.

BACKGROUND: Smoking status has not been shown to have a significant effect on 30-day mortality after potentially curative resectional surgery for non-small-cell lung cancer, and this is reflected in the guidelines of the National Institute for Health and Care Excellence in the United Kingdom. METHODS: A validated prospective thoracic surgery database of consecutive patients undergoing potentially curative resection at a single institution was analyzed. Univariate and propensity analyses of 30-day mortality were performed. RESULTS: Univariate analysis identified 30-day mortality as significantly lower in current smokers (n = 852, 2.6%) than ex-smokers (n = 1587, 4.9%; p < 0.001). Propensity 1:1 matching of male patients resulted in 727 current smokers being matched to 727 ex-smokers. The overall balance test (χ(2 )= 6.1, degrees of freedom = 8, p = 0.6), indicated a good match. After propensity matching, the mortality rate was significantly higher in current smokers (p = 0.01). CONCLUSIONS: Current smokers and ex-smokers are statistically different with regard to risk factors for death. This results in a skewed population of current and ex-smokers undergoing resection for non-small-cell lung cancer. Development of a risk model for 30-day mortality revealed that current smokers have a lower predicted 30-day mortality than ex-smokers, a finding that is counterintuitive. Propensity matching balanced the current and ex-smoker groups to correct for group differences. Analysis after propensity matching identified current smoking as a significant factor determining 30-day mortality.

OBJECTIVES: To determine if the use of cardiopulmonary bypass is associated with all-cause in-hospital and mid-term survival for patients undergoing left internal mammary artery (LIMA) to left anterior descending (LAD) coronary artery bypass grafting (CABG) for single coronary vessel disease. METHODS: Data from the National Adult Cardiac Surgery Audit registry for all elective and urgent isolated CABG procedures performed between April 2003 and March 2013 in first-time cardiac surgery patients were extracted. Experienced surgeons (those with ≥300 records) were classified by their technique preference (as 'off-pump preference', 'mixed practice', 'on-pump preference') based on their entire isolated CABG data. In-hospital mortality and time to death were analysed using logistic and Cox proportional hazards regression models, respectively. RESULTS: From a total of 3402 records, 65.5% were performed off-pump. There were 16 (0.47%) in-hospital deaths: 6 (0.51%) in the on-pump group and 10 (0.45%) in the off-pump group. The risk-adjusted odds ratio of in-hospital mortality in the direction of on-pump was 1.09 [95% confidence interval (CI): 0.39-3.04; P = 0.86]. The overall 5-year survival in the on- and off-pump groups was 93.1 and 93.4%, respectively. The adjusted hazard ratio (HR) for mortality in the direction of on-pump CABG was 1.15 (95% CI: 0.89-1.49; P = 0.28). Comparing off-pump cases performed by experienced CABG surgeons with a preference for the off-pump technique with on-pump cases performed by surgeons with a preference for the on-pump technique indicated a significant difference (HR for on-pump = 1.72; 95% CI: 1.19-2.47; P = 0.004). CONCLUSIONS: Elective and urgent first-time CABG for isolated LAD disease is associated with excellent mid-term survival in the England and Wales population, conferring a 5-year survival rate of 93.1 and 93.4% in the on-pump and off-pump groups, respectively. There was no difference in risk-adjusted survival between the on-pump and off-pump techniques when analysing all procedures; however, supportive analysis demonstrated that off-pump surgery performed by experienced surgeons with a preference for the off-pump technique in their CABG caseload is associated with improved mid-term survival when compared with on-pump surgery performed by surgeons with a preference for the on-pump technique.

Gaps remain in our understanding of the contribution of bypass-related practices associated with red blood cell (RBC) transfusions after cardiac surgery. Variability exists in the reporting of bypass-related practices in the peer-reviewed literature. In an effort to create uniformity in reporting, a draft statement outlining proposed minimal criteria for reporting cardiopulmonary bypass (CPB)- related contributions (i.e., RBC data collection/documentation, clinical considerations for transfusions, equipment details, and clinical endpoints) was presented in conjunction with the American Society of ExtraCorporeal Technology's (AmSECT's) 2014 Quality and Outcomes Meeting (Baltimore, MD). Based on presentations and feedback from the conference, coauthors (n = 14) developed and subsequently voted on each proposed data element. Data elements receiving a total of 4 votes were dropped from further consideration, 5-9 votes were considered as "Recommended," and elements receiving ≥10 votes were considered as "Mandatory." A total of 52 elements were classified as mandatory, 16 recommended, and 14 dropped. There are 8 mandatory data elements for RBC data collection/documentation, 24 for clinical considerations for transfusions, 13 for equipment details, and 7 for clinical endpoints. We present 52 mandatory data elements reflecting CPB-related contributions to RBC transfusions. Consistency of such reporting would offer our community an increased opportunity to shed light on the relationship between intra-operative practices and RBC transfusions.
