RESUMO
OBJECTIVE: To evaluate short-term outcomes and statewide practice patterns of prophylactic left atrial appendage ligation (P-LAAL) in coronary artery bypass grafting (CABG) patients without pre-operative atrial fibrillation (AF). METHODS: Adult patients who underwent an on-pump CABG (2017 - 2023) within a regional collaborative were identified. Patients with a history of AF, previous cardiac surgery, or non-device based LAAL were excluded. Patients were stratified by LAAL status and were propensity score matched. Univariable analysis was used to compare short-term clinical outcomes. RESULTS: Of 16,547 patients examined, 442 underwent P-LAAL. The propensity score matched cohort (439 P-LAAL, 439 No P-LAAL) was compared and had no significant differences in pre-operative CHA2DS2-VASc scores or operative variables. The P-LAAL group had longer cross clamp time (82 vs 76 minutes, p=0.001), ICU hours (72 vs 66, p=0.001), length of stay (6.0 vs 6.0 days, p=0.010), increased post-operative AF (35% vs 24%, p<0.001), and more discharge on anticoagulation (17% vs 8.2%, p<0.001). There were no significant differences in post-operative stroke (1.1% vs 2.1%, p=0.423), readmission (13% vs 9.6%, p=0.118), operative mortality (2.5% vs 1.6%, p=0.480), or readmission for thrombotic or bleeding complications (0.7% vs 1.1%, p=0.724). Hospitalization costs were significantly higher for P-LAAL patients ($43,478 vs $40,645, p<0.001). The rate of P-LAAL during CABG increased from 1.61% (2017) to 5.65% (2023) (p<0.001). CONCLUSIONS: Despite higher rates of post-operative AF, discharge on anticoagulation, and hospitalization costs in patients undergoing P-LAAL during CABG, there was no difference in short-term clinical endpoints including stroke and operative mortality.
RESUMO
OBJECTIVE: The impact of Cardiac Surgical Unit - Advanced Life Support (CSU-ALS) training on failure to rescue after cardiac arrest (FTR-CA) is unknown. We hypothesized that institutional CSU-ALS certification would be associated with lower FTR-CA. METHODS: Patients undergoing Society of Thoracic Surgeons (STS) index operations from 2020-2023 from a regional collaborative were analyzed. Each institution was surveyed regarding its status as a CSU-ALS certified center. Patients stratified by CSU-ALS certification were 1:1 propensity score matched with subsequent multivariable model reviewing associations with failure to rescue after cardiac arrest. RESULTS: A total of 12209 patients were included in the study period across 15 institutions. Eight centers reported CSU-ALS certification. After propensity score matching, two patient cohorts were formed (n = 3557). Patients at CSU-ALS centers had higher rates of ICU readmission (3.9% vs 2.3%, p<0.01) and total OR time (340 min vs 323 min, p<0.01). Hospital readmission was less likely in the CSU-ALS centers (9.0% vs 10.1%, p <0.01). There was no difference in the rate of post-operative cardiac arrest (1.8% vs 2.2 %, p = 0.24) or operative mortality (2.5% vs 2.9%, p = 0.30). After risk-adjustment, CSU-ALS centers (OR 0.30 [CI 0.12 - 0.72], p <0.01) and higher-volume centers (OR 0.15 [CI 0.03 - 0.74], p = 0.02) had reduced odds of FTR after cardiac arrest. CONCLUSIONS: Centers with CSU-ALS certification are associated with a lower risk-adjusted likelihood of FTR after cardiac arrest. This highlights the importance of well-trained staff and treatment algorithms in the care of post-operative cardiac surgery patients.
RESUMO
BACKGROUND: Due to staffing changes at scheduled intervals and decreases in essential staff in the evenings, late intensive care unit (ICU) arrivals may be at risk for suboptimal outcomes. Utilizing a regional collaborative, we sought to determine the effect of ICU arrival timing on outcomes in elective isolated coronary artery bypass (CABG). METHODS: Adults undergoing elective, isolated CABG from 17 hospitals between 2013-2023 were identified. Patients with missing predicted risk of mortality or missing ICU arrival time were excluded. Late ICU arrival time was defined as between 18:00-06:00. Hierarchical logistic regression with appropriate predicted risk scores was utilized for outcome risk adjustment. RESULTS: We identified 11,638 patients, with 972 (8.4%) experiencing late ICU arrival. Late ICU arrival patients had higher predicted risk of morbidity or mortality (8.2% [5.6%, 12.0% vs. 7.7% [5.5%, 11.5%], p=0.048) compared to early ICU arrival patients with longer median cardiopulmonary bypass times (96 minutes [78, 119] vs. 93 [73, 116], p<0.001). Late ICU arrival patients experienced more unadjusted complications including prolonged ventilation (7.7% vs. 4.2%, p<0.001) and operative mortality (2.0% vs. 1.1%, p=0.02), although no difference in failure-to-rescue (11.0% vs. 10.4%%, p=0.84). Logistic regression with risk adjustment demonstrated late ICU arrival as a predictor of prolonged ventilation (OR=1.49 [1.12-1.99], p=0.006). CONCLUSIONS: Following adjustment, late ICU arrivals experienced higher rates of prolonged ventilation, although this did not translate to failure-to-rescue.
RESUMO
BACKGROUND: The utility of operating room extubation (ORE) after cardiac surgery over fast-track extubation (FTE) within 6 hours remains contested. We hypothesized ORE would be associated with equivalent rates of morbidity and mortality, relative to FTE. METHODS: Patients undergoing nonemergent cardiac surgery were identified in The Society of Thoracic Surgeons Adult Cardiac Surgery Database between July 2017 and December 2022. Only procedures with The Society of Thoracic Surgeons risk models were included. Risk-adjusted outcomes of ORE and FTE were compared by observed-to-expected ratios with 95% CIs aggregated over all procedure types, and ORE vs FTE adjusted odds ratios (ORs) specific to each procedure type using multivariable logistic regression. Analyzed outcomes were operative mortality, prolonged length of stay, composite reoperation for bleeding and reintubation, and composite morbidity and mortality. RESULTS: The study population of 669,099 patients across 1069 hospitals included 36,298 ORE patients in 296 hospitals. Risk-adjusted analyses found that ORE was associated with statistically similar or better results across each of the 4 outcomes and procedure subtypes. Notably, rates of postoperative mortality were significantly lower in ORE patients undergoing coronary artery bypass grafting (OR, 0.54; 95% CI, 0.46-0.65), aortic valve replacement (OR, 0.43; 95% CI, 0.24-0.77), and mitral valve replacement (OR, 0.48; 95% CI, 0.26-0.89). CONCLUSIONS: Extubation in the OR was safe and effective in a selected patient population and may be associated with superior outcomes in coronary artery bypass, aortic valve replacement, and mitral valve replacement. These national data appear to confirm institutional experiences regarding the potential benefit of OR extubation. Further refinement of optimal populations may justify randomized investigation.

Objective: Mitral valve repair is the gold standard for treatment of mitral regurgitation, but the optimal technique remains debated. By using a regional collaborative, we sought to determine the change in repair technique over time. Methods: We identified all patients undergoing isolated mitral valve repair from 2012 to 2022 for degenerative mitral disease. Those with endocarditis, transcatheter repair, or tricuspid intervention were excluded. Continuous variables were analyzed via Wilcoxon rank sum, and categorical variables were analyzed via chi-square testing. Results: We identified 1653 patients who underwent mitral valve repair, with 875 (59.2%) undergoing a no resection repair. Over the last decade, there was no significant trend in the proportion of repair techniques across the region (P = .96). Those undergoing no resection repairs were more likely to have undergone prior cardiac surgery (5.0% vs 2.2%, P = .002) or minimally invasive approaches (61.4% vs 24.7%, P < .001) with similar predicted risk of mortality (median 0.6% vs 0.6%, P = .75). Intraoperatively, no resection repairs were associated with longer bypass times (140 [117-167] minutes vs 122 [91-159] minutes, P < .001). Operative mortality was similar between both groups (1.1% vs 1.0%, P = .82), as were other postoperative outcomes. Anterior leaflet prolapse (odds ratio, 11.16 [6.34-19.65], P < .001) and minimally invasive approach (odds ratio, 6.40 [5.06-8.10], P < .001) were most predictive of no resection repair. Conclusions: Despite minor differences in operative times, statewide over the past decade there remains a diverse mix of both classic "resect" and newer "respect" strategies with comparable short-term outcomes and no major timewise trends. These data may suggest that both approaches are equivocal.
RESUMO
BACKGROUND: Differences in outcomes by indication for venoarterial extracorporeal life support (VA-ECLS) are poorly described. We hypothesized that patients on VA-ECLS for acute pulmonary embolism (PE) have fewer complications and better survival than patients on VA-ECLS for other indications. METHODS: All patients ≥18 years on VA-ECLS from the Extracorporeal Life Support Organization global registry (2010-2019) were evaluated (n = 29,842). After excluding patients aged >79 years (n = 729) and those with incomplete indication data (n = 2530), patients were stratified by VA-ECLS indication for PE vs all other indications. The association between being discharged alive and each type of complication with VA-ECLS indication was assessed. RESULTS: Of 26,583 patients included in the analysis, 978 (3.7%) were on VA-ECLS for a primary diagnosis of acute PE. Acute PE patients were younger (53.1 vs 56.7 years, P < .001) and were more likely to be women (52.1% vs 32.3%, P < .001). Patients who underwent VA-ECLS for acute PE were 78% more likely to be discharged alive vs patients supported with VA-ECLS for other reasons (52.8% vs 40.4%; P < .001). Acute PE patients had fewer cardiovascular and renal complications (26.6% vs 38.0% and 31.1% vs 39.4%, respectively; adjusted P < .001). Acute PE patients had higher odds of having clots and mechanical complications (8.7% vs 7.9% and 16.7% vs 14.6%, respectively; adjusted P < .001). CONCLUSIONS: Patients undergoing VA-ECLS for acute PE have higher odds of survival to hospital discharge compared with those supported for other indications. Additionally, VA-ECLS in this population is associated with fewer cardiovascular and renal complications but higher mechanical complications.

OBJECTIVE: Psoas muscle size is a reliable marker of sarcopenia and frailty that correlates with adverse outcomes after cardiac surgery. However, its use in mitral and minimally invasive cardiac surgery is lacking. We sought to determine whether frailty, as measured by psoas muscle index, increases surgical risk for minimally invasive mitral valve surgery. METHODS: Patients undergoing isolated minimally invasive mitral surgery via right minithoracotomy were identified. Patients who underwent maze, tricuspid intervention, and those who were emergent were excluded. Total psoas muscle area was calculated using the average cross-sectional area at the L3 vertebra on computed tomography scan and indexed to body surface area. Sarcopenia was defined as <25th gender-specific percentile. Patients were stratified by sarcopenia status and outcomes compared. RESULTS: Of 287 total patients, 192 patients met inclusion criteria. Sarcopenic patients were 6 years older (66 vs 60 years, P = 0.01), had lower preoperative albumin levels (4.0 vs 4.3 g/dL, P < 0.001), and had higher Society of Thoracic Surgeons risk of morbidity/mortality (13.1% vs 9.0%, P = 0.003). Operative major morbidity or mortality was 6.4% versus 5.5% (P = 0.824), while the 1-year mortality rate was 2.1% versus 0% (P = 0.08). After risk adjustment, psoas index did not predict operative morbidity or mortality. However, sarcopenia was associated with higher odds of readmission (odds ratio = 0.74, P = 0.02). CONCLUSIONS: Contrary to other cardiac operations, for patients undergoing isolated minimally invasive mitral valve surgery, sarcopenia was not associated with increased perioperative risk except for higher readmission rates. Minimally invasive surgical approaches should be strongly considered as the approach of choice in frail patients.

OBJECTIVE: The influence of Extracorporeal Life Support Organization (ELSO) center of excellence (CoE) recognition on failure to rescue after cardiac surgery is unknown. We hypothesized that ELSO CoE would be associated with improved failure to rescue. METHODS: Patients undergoing a Society of Thoracic Surgeons index operation in a regional collaborative (2011-2021) were included. Patients were stratified by whether or not their operation was performed at an ELSO CoE. Hierarchical logistic regression analyzed the association between ELSO CoE recognition and failure to rescue. RESULTS: A total of 43,641 patients were included across 17 centers. In total, 807 developed cardiac arrest with 444 (55%) experiencing failure to rescue after cardiac arrest. Three centers received ELSO CoE recognition, and accounted for 4238 patients (9.71%). Before adjustment, operative mortality was equivalent between ELSO CoE and non-ELSO CoE centers (2.08% vs 2.36%; P = .25), as was the rate of any complication (34.5% vs 33.8%; P = .35) and cardiac arrest (1.49% vs 1.89%; P = .07). After adjustment, patients undergoing surgery at an ELSO CoE facility were observed to have 44% decreased odds of failure to rescue after cardiac arrest, relative to patients at non-ELSO CoE facility (odds ratio, 0.56; 95% CI, 0.316-0.993; P = .047). CONCLUSIONS: ELSO CoE status is associated with improved failure to rescue following cardiac arrest for patients undergoing cardiac surgery. These findings highlight the important role that comprehensive quality programs serve in improving perioperative outcomes in cardiac surgery.

OBJECTIVE: Renal failure after cardiac surgery is associated with increased morbidity and mortality. There is a lack of data examining the rate of renal recovery after patients have started dialysis following cardiac surgery. We aimed to determine the frequency of and time to renal recovery of patients requiring dialysis after cardiac surgery. METHODS: All patients who developed new-onset renal failure requiring dialysis following cardiac surgery at our institution from 2011 to 2022 were included. Renal recovery, time to renal recovery, and mortality at 1 year were merged with patients' Society of Thoracic Surgeons Adult Cardiac Surgery Database files. Kaplan-Meier analysis was used to predict time to renal recovery; we censored patients who died or were lost to follow up. Cox regression was used for risk-adjustment. RESULTS: A total of 312 patients were included in the final analysis. Mortality during index hospital admission was 33% (n = 105), and mortality at 1 year was 45% (n = 141). Of those surviving at 1 year, 69% (n = 118) remained renally recovered. Median renal recovery time was 56 (37-74) days. Accounting for mortality as a competing risk, 51% of patients were predicted to achieve renal recovery. Increasing age (hazard ratio, 0.98; 0.514-0.94, P < .026) and increasing total packed red blood cells (hazard ratio, 0.0958; 0.937-0.987, P < .001) received were found to be significant negative predictors of renal recovery in the Fine-Gray model for subhazard distribution. CONCLUSIONS: More than two-thirds of patients with renal failure who survived the perioperative period had renal recovery within 1 year after surgery. Recovery was driven primarily by postoperative complications rather than comorbidities and intraoperative factors, suggesting renal failure in the postoperative cardiac surgery patient surviving to discharge is unlikely to be permanent.
RESUMO
OBJECTIVE: Literature describing outcomes of myocardial ischemia after coronary artery bypass grafting is sparse. We hypothesized these patients had more complications and incurred higher costs of care. METHODS: Using adult cardiac surgery data and cardiac catheterization (CathPCI) data from the Virginia Cardiac Services Quality Initiative, we identified patients who underwent unplanned cardiac catheterization after coronary artery bypass grafting from 2018 to 2021. Adult cardiac surgery data were matched to CathPCI data examining earliest in-hospital catheterization. Patients not requiring catheterization served as the control group. RESULTS: We identified 10,597 patients who underwent isolated coronary artery bypass grafting, of whom 41 of 10,597 underwent unplanned cardiac catheterization. A total of 21 of 41 patients (51%) received percutaneous coronary intervention, most commonly for non-ST-elevation myocardial infarction (n = 7, 33%) and ST-elevation myocardial infarction (n = 6, 29%). Postoperative cardiac arrest occurred in 14 patients (40%). In patients who underwent percutaneous coronary intervention, 14 (67%) had a single lesion, 4 (19%) had 2 lesions, and 3 (14%) had 3 lesions. The left anterior descending artery (38%) was the most frequently intervened upon vessel. Patients who underwent catheterization were more likely to require balloon pump support (26% vs 11%), to have prolonged ventilation (57% vs 20%), to have renal failure (17% vs 7.1%), and to undergo reintubation (37% vs 3.8%, all P < .04). There was no statistical difference in operative mortality (4.9% vs 2.3%, P = .2) or failure to rescue (4.9% vs 1.6%, P = .14). Total costs were higher in patients who underwent unplanned catheterization ($81,293 vs $37,011, P < .001). CONCLUSIONS: Unplanned catheterization after coronary artery bypass grafting is infrequent but associated with more complications and a higher cost of care. Therefore, determination of an association with operative mortality in patients with suspected ischemia after coronary artery bypass grafting requires additional study.
RESUMO
Background Adults undergoing heart surgery are particularly vulnerable to respiratory complications, including COVID-19. Immunization can significantly reduce this risk; however, the effect of cardiopulmonary bypass (CPB) on immunization status is unknown. We sought to evaluate the effect of CPB on COVID-19 vaccination antibody concentration after cardiac surgery. Methods and Results This prospective observational clinical trial evaluated adult participants undergoing cardiac surgery requiring CPB at a single institution. All participants received a full primary COVID-19 vaccination series before CPB. SARS-CoV-2 spike protein-specific antibody concentrations were measured before CPB (pre-CPB measurement), 24 hours following CPB (postoperative day 1 measurement), and approximately 1 month following their procedure. Relationships between demographic or surgical variables and change in antibody concentration were assessed via linear regression. A total of 77 participants were enrolled in the study and underwent surgery. Among all participants, mean antibody concentration was significantly decreased on postoperative day 1, relative to pre-CPB levels (-2091 AU/mL, P<0.001). Antibody concentration increased between postoperative day 1and 1 month post CPB measurement (2465 AU/mL, P=0.015). Importantly, no significant difference was observed between pre-CPB and 1 month post CPB concentrations (P=0.983). Two participants (2.63%) developed symptomatic COVID-19 pneumonia postoperatively; 1 case of postoperative COVID-19 pneumonia resulted in mortality (1.3%). Conclusions COVID-19 vaccine antibody concentrations were significantly reduced in the short-term following CPB but returned to pre-CPB levels within 1 month. One case of postoperative COVID 19 pneumonia-specific mortality was observed. These findings suggest the need for heightened precautions in the perioperative period for cardiac surgery patients.

INTRODUCTION: Deep sternal wound infection (DSWI) is a rare complication associated with high mortality. Seasonal variability in surgical site infections has been demonstrated, however, these patterns have not been applied to DSWI. The purpose of this study was to assess temporal clustering of DSWIs. METHODS: All cardiac surgery patients who underwent sternotomy were queried from a regional Society of Thoracic Surgeons database from 17 centers from 2001 to 2019. All patients with the diagnosis of DSWI were then identified. Cluster analysis was performed at varying time intervals (monthly, quarterly, and yearly) at the hospital and regional level. DSWI rates were calculated by year and month, and compared using mixed-effects negative binomial regression. RESULTS: A total of 134,959 patients underwent a sternotomy for cardiac surgery, of whom 469 (0.35%) developed a DSWI. Rates of DSWI per hospital across all years ranged from 0.12% to 0.69%. Collaborative-level rates of DSWIs were the greatest in September (0.44%) and the lowest in January (0.30%). Temporal clustering was not seen across seasonal quarters (high rate in preceeding quarter was not associated with a high rate in the next quarter) (P = 0.39). There were yearly differences across all institutions in the DSWI rates. A downward trend in DSWI rates was seen from 2001 to 2019 (P < 0.001). A difference among hospitals in the cohort was observed (P < 0.001). CONCLUSIONS: DSWI are a rare event within our region. Unlike other surgical site infection, there does not appear to be a seasonal pattern associated with DSWI.

BACKGROUND: Failure to rescue (FTR) is a new quality measure in The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database. The STS defines FTR as death after permanent stroke, renal failure, reoperation, or prolonged ventilation. Our objective was to assess whether cardiac arrest should be included in this definition. METHODS: Patients undergoing an STS index operation in a regional collaborative (2011-2021) were included. The performance of the STS definition of FTR was compared with a definition that included the STS complications plus cardiac arrest (STS+). Centers were grouped into FTR rate terciles using the STS and STS+ definitions of FTR, and changes in their relative performance rating were assessed. RESULTS: A total of 43,641 patients were included across 17 centers. Cardiac arrest was the most lethal complication: 55.0% of patients who experienced cardiac arrest died. FTR after any complication (13 total) occurred among 884 patients. The STS definition of FTR accounted for 83% (735 of 884) of all FTR. The addition of cardiac arrest to the STS definition significantly increased the proportion of overall FTR accounted for (92.2% [815 of 884]; P < .001). Choice of FTR definition led to substantial differences in center-level relative performance rating by FTR rate. CONCLUSIONS: Mortality after cardiac arrest is not completely captured by the STS definition of FTR and represents an important source of potentially preventable death after cardiac surgery. Future quality improvement efforts using the STS definition of FTR should account for this.

OBJECTIVE: Our understanding of the impact of a center's case volume on failure to rescue (FTR) after cardiac surgery is incomplete. We hypothesized that increasing center case volume would be associated with lower FTR. METHODS: Patients undergoing a Society of Thoracic Surgeons index operation in a regional collaborative (2011-2021) were included. After we excluded patients with missing Society of Thoracic Surgeons Predicted Risk of Mortality scores, patients were stratified by mean annual center case volume. The lowest quartile of case volume was compared with all other patients. Logistic regression analyzed the association between center case volume and FTR, adjusting for patient demographics, race, insurance, comorbidities, procedure type, and year. RESULTS: A total of 43,641 patients were included across 17 centers during the study period. Of these, 5315 (12.2%) developed an FTR complication, and 735 (13.8% of those who developed an FTR complication) experienced FTR. Median annual case volume was 226, with 25th and 75th percentile cutoffs of 136 and 284 cases, respectively. Increasing center-level case volume was associated with significantly greater center-level major complication rates but lower mortality and FTR rates (all P values < .01). Observed-to-expected FTR was significantly associated with case volume (P = .040). Increasing case volume was independently associated with decreasing FTR rate in the final multivariable model (odds ratio, 0.87 per quartile; confidence interval, 0.799-0.946, P = .001). CONCLUSIONS: Increasing center case volume is significantly associated with improved FTR rates. Assessment of low-volume centers' FTR performance represents an opportunity for quality improvement.
RESUMO
Objectives: The 2018 change in the heart transplant allocation system resulted in greater use of temporary mechanical circulatory support. We hypothesized that the allocation change has increased hospital resource utilization, including length of stay and cost. Methods: All heart transplant patients within a regional Society of Thoracic Surgeons database were included (2012-2020). Patients were stratified before and after the transplant allocation changes into early (January 2012-September 2018) and late eras (November 2018-June 2020). Costs were adjusted for inflation and presented in 2020 dollars. Results: Of 535 heart transplants, there were 410 early and 125 late era patients. Baseline characteristics were similar, except for greater lung and valvular disease in the late era. Fewer patients in the late era were bridged with durable left ventricular assist devices (69% vs 31%; P < .0001), biventricular devices (5% vs 1%; P = .047), and more with temporary mechanical circulatory support (4% vs 46%; P < .0001). There was no difference in early mortality (6% vs 4%; P = .33) or major morbidity (57% vs 61%; P = .40). Length of stay was longer preoperatively (1 vs 9 days; P < .0001), but not different postoperatively. There was no difference in median total hospital cost ($132,465 vs $128,996; P = .15), although there was high variability. On multivariable regression, preoperative extracorporeal membrane oxygenation utilization was the main driver of resource utilization. Conclusions: The new heart transplant allocation system has resulted in different bridging techniques, with greater reliance on temporary mechanical circulatory support. Although this is associated with an increase in preoperative length of stay, it did not translate into increased hospital cost.
RESUMO
BACKGROUND: Cardiac postoperative intensive care unit (ICU) beds are a limited resource, and when a patient no longer requires this level of care they are quickly transferred out. We hypothesized that complications and ICU readmission increased when transfer occurred during off-hours compared with regular work hours. METHODS: From 2010 to 2021, patients who underwent a Society of Thoracic Surgeons index operation at a single center were assigned a group based on their ICU transfer time, defined as when they physically arrived on the acute care floor. Patients were stratified into off-hours vs regular hours by their transfer time. Off-hours was defined as 9 pm to 5 am. Risk-adjusted multivariable logistic regression analyzed the association of ICU readmission, postoperative complications, operative mortality, and failure to rescue by group. RESULTS: The cohort included 5951 patients (off-hours n = 292 [4.9%], regular-hours n = 5659 [95.1%]). Patients in the off-hours group had significantly greater odds of risk-adjusted ICU readmission (odds ratio 1.99, 95% CI 1.25-3.04, P < .002) and mortality (odds ratio 3.88, 95% CI 2.27-6.33, P < .001). In the major complications subgroup (Off-hours n = 55, Regular-hours n = 603), Off-hours transfer was associated with increased mortality (failure to rescue) (odds ratio 3.05, 95% CI 1.58-5.69, P = .001). CONCLUSIONS: Off-hours ICU to floor transfer was associated with increased postoperative complications, ICU readmission, and mortality, suggesting that the timing of ICU transfer may impact outcomes. This elucidates targets for quality and process improvement for our center and others facing the same resource constraints.

BACKGROUND: Employment is an important metric of post-transplant functional status and the quality of life yet remains poorly described after heart transplant. We sought to characterize the prevalence of employment following heart transplantation and identify patients at risk for post-transplant unemployment. METHODS: Adults undergoing single-organ heart transplantation (2007-2016) were evaluated using the UNOS database. Univariable analysis was performed after stratifying by employment status at 1-year post-transplant. Fine-Gray competing risk regression was used for risk adjustment. Cox regression evaluated employment status at 1 year with mortality. RESULTS: Of 10,132 heart transplant recipients who survived to 1 year and had follow-up, 22.0% were employed 1-year post-transplant. Employment rate of survivors increased to 32.9% by year 2. Employed individuals were more likely white (70.8% vs 60.4%, p < 0.01), male (79.6% vs 70.7% p < 0.01), held a job at listing/transplant (37.6% vs 7.6%, p < 0.01), and had private insurance (79.1% vs 49.5%, p < 0.01). Several characteristics were independently associated with employment including age, employment status at time of listing or transplant, race and ethnicity, gender, insurance status, education, and postoperative complications. Of 1,657 (14.0%) patients employed pretransplant, 58% were working at 1-year. Employment at 1year was independently associated with mortality with employed individuals having a 26% decreased risk of mortality. CONCLUSION: Over 20% of heart transplant patients were employed at 1 year and over 30% at 2 years, while 58% of those working pretransplant had returned to work by 1-year. While the major predictor of post-transplant employment is preoperative employment status, our study highlights the impact of social determinants of health.

BACKGROUND: Increasing socioeconomic distress has been associated with worse cardiac surgery outcomes. The extent to which the pandemic affected cardiac surgical access and outcomes remains unknown. We sought to examine the relationship between the COVID-19 pandemic and outcomes after cardiac surgery by socioeconomic status. METHODS: All patients undergoing a Society of Thoracic Surgeons (STS) index operation in a regional collaborative, the Virginia Cardiac Services Quality Initiative (2011-2022), were analyzed. Patients were stratified by timing of surgery before vs during the COVID-19 pandemic (March 13, 2020). Hierarchic logistic regression assessed the relationship between the pandemic and operative mortality, major morbidity, and cost, adjusting for the Distressed Communities Index (DCI), STS predicted risk of mortality, intraoperative characteristics, and hospital random effect. RESULTS: A total of 37,769 patients across 17 centers were included. Of these, 7269 patients (19.7%) underwent surgery during the pandemic. On average, patients during the pandemic were less socioeconomically distressed (DCI 37.4 vs DCI 41.9; P < .001) and had a lower STS predicted risk of mortality (2.16% vs 2.53%, P < .001). After risk adjustment, the pandemic was significantly associated with increased mortality (odds ratio 1.398; 95% CI, 1.179-1.657; P < .001), cost (+$4823, P < .001), and STS failure to rescue (odds ratio 1.37; 95% CI, 1.10-1.70; P = .005). The negative impact of the pandemic on mortality and cost was similar regardless of DCI. CONCLUSIONS: Across all socioeconomic statuses, the pandemic is associated with higher cost and greater risk-adjusted mortality, perhaps related to a resource-constrained health care system. More patients during the pandemic were from less distressed communities, raising concern for access to care in distressed communities.

In light of the worsening opioid epidemic and nationwide parenteral opioid shortage, our institution created an enhanced recovery after surgery (ERAS) protocol. Our objective was to evaluate our initial experience transitioning to ERAS in cardiac surgery. An institutional cardiac ERAS protocol was implemented in April 2018, consisting of opioid-sparing analgesia, liberalization of fasting and activity restrictions, and goal-directed standardization of perioperative care. Clinical outcomes, opioid administration, and pain scores of patients undergoing nonemergent cardiac surgery were reviewed from March 2017 to July 2018. Patients were propensity score matched into pre-ERAS and transition-to-ERAS (t-ERAS) cohorts and compared by univariate analysis. Of 467 patients, 236 patients were well-matched (118 per cohort). The transition to ERAS resulted in a 79% reduction in morphine equivalents through postoperative day 1 (359.3 mg pre-ERAS vs 75.4 mg ERAS, P < 0.0001). Despite less opioid utilization, t-ERAS patients reported lower pain scores (median 4.88 vs 4.14, P = 0.011). There was no difference in mortality (2% vs 0%, P = 0.498) or postoperative complications including initial hours ventilated (5.3 vs 5.2 hours, P = 0.380), prolonged ventilation (9.3% vs 6.8%, P = 0.473), renal failure (3.4% vs 2.5%, P = 0.701), and ICU length of stay (58.3 vs 70.4 hours, P = 0.272). The transition to cardiac ERAS resulted in significantly reduced opioid administration and improved patient pain scores while maintaining excellent outcomes. Well-supported, multidisciplinary teams of cardiac surgeons, anesthesiologists, and intensivists can dramatically reduce opioid use without sacrificing pain control or excellent clinical outcomes.
