RESUMEN
Variability persists in intraoperative red blood cell (RBC) transfusion rates, despite evidence supporting associated adverse sequelae. We evaluated whether beliefs concerning transfusion risk and safety are independently associated with the inclination to transfuse. We surveyed intraoperative transfusion decision-makers from 33 cardiac surgery programs in Michigan. The primary outcome was a provider's reported inclination to transfuse (via a six-point Likert Scale) averaged across 10 clinical vignettes based on Class IIA or IIB blood management guideline recommendations. Survey questions assessed hematocrit threshold for transfusion ("hematocrit trigger"), demographic and practice characteristics, years and case-volume of practice, knowledge of transfusion guidelines, and provider attitude regarding perceived risk and safety of blood transfusions. Linear regression models were used to estimate the effect of these variables on transfusion inclination. Mixed effect models were used to quantify the variation attributed to provider specialties and hematocrit triggers. The mean inclination to transfuse was 3.2 (might NOT transfuse) on the survey Likert scale (SD: .86) across vignettes among 202/413 (48.9%) returned surveys. Hematocrit triggers ranged from 15% to 30% (average: 20.4%; SE: .18%). The inclination to transfuse in situations with weak-to-moderate evidence for supporting transfusion was associated with a provider's hematocrit trigger (p < .01) and specialty. Providers believing in the safety of transfusions were significantly more likely to transfuse. Provider specialty and belief in transfusion safety were significantly associated with a provider's hematocrit trigger and likelihood for transfusion. Our findings suggest that blood management interventions should target these previously unaccounted for blood transfusion determinants.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) for the treatment of aortic stenosis in patients at intermediate, high, and extreme risk for mortality from SAVR. We examined recent trends in aortic valve replacement (AVR) in Michigan. METHODS: The Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative (MSTCVS-QC) database was used to determine the number of SAVR and TAVR cases performed from January 2012 through June 2017. Patients were divided into low, intermediate, high, and extreme risk groups based on STS predicted risk of mortality (PROM). TAVR patients in the MSTCVS-QC database were also matched with those in the Transcatheter Valve Therapy Registry to determine their Heart Team-designated risk category. RESULTS: During the study period 9517 SAVR and 4470 TAVR cases were performed. Total annual AVR volume increased by 40.0% (from 2086 to 2920), with a 13.3% decrease in number of SAVR cases (from 1892 to 1640) and a 560% increase in number of TAVR cases (from 194 to 1280). Greater than 90% of SAVR patients had PROM ≤8%. While >70% of TAVR patients had PROM ≤ 8%, they were mostly designated as high or extreme risk by a Heart Team. CONCLUSIONS: During the study period, SAVR volume gradually declined and TAVR volume dramatically increased. This was mostly due to a new group of patients with lower STS PROM who were designated as higher risk by a Heart Team due to characteristics not completely captured by the STS PROM score.

BACKGROUND: While large volumes of red blood cell transfusions are given to preserve life for cardiac surgical patients, indications for lower volume transfusions (1-2 units) are less well understood. We evaluated the relationship between center-level organizational blood management practices and center-level variability in low volume transfusion rates. METHODS: All 33 nonfederal, Michigan cardiac surgical programs were surveyed about their blood management practices for isolated, nonemergent coronary bypass procedures, including: (1) presence and structure of a patient blood management program, (2) policies and procedures, and (3) audit and feedback practices. Practices were compared across low (N = 14, rate: 0.8%-10.1%) and high (N = 18, rate: 11.0%-26.3%) transfusion rate centers. RESULTS: Thirty-two (97.0%) of 33 institutions participated in this study. No statistical differences in organizational practices were identified between low- and high-rate groups, including: (1) the membership composition of patient blood management programs among those reporting having a blood management committee (P= .27-1.0), (2) the presence of available red blood cell units within the operating room (4 of 14 low-rate versus 2 of 18 high-rate centers report that they store no units per surgical case, P= .36), and (3) the frequency of internal benchmarking reporting about blood management audit and feedback practices (low rate: 8 of 14 versus high rate: 9 of 18; P= .43). CONCLUSIONS: We did not identify meaningful differences in organizational practices between low- and high-rate intraoperative transfusion centers. While a larger sample size may have been able to identify differences in organizational practices, efforts to reduce variation in 1- to 2-unit, intraoperative transfusions may benefit from evaluating other determinants, including organizational culture and provider transfusion practices.

BACKGROUND: Red blood cell (RBC) transfusions have been associated with morbidity and mortality in both coronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCI). As a mechanism for identifying determinants of RBC practice, we quantified the relationship between a center's PCI and CABG transfusion rate. METHODS: We identified all patients undergoing CABG (n = 16,568) or PCI (n = 94,634) at each of 33 centers from 2010 through 2012 in the state of Michigan and compared perioperative RBC transfusion rates for CABG and PCI at each center. Crude and adjusted transfusion rates were modeled separately. We adjusted for common preprocedural risk factors (12 for CABG and 23 for PCI) and reported Pearson correlation coefficients based on the crude and risk-adjusted rates. RESULTS: As expected, RBC transfusion was more common after CABG (mean 46.5%) than PCI (mean 3.3%), with wide variation across centers for both (CABG min:max 26.5:71.3, PCI min:max 1.6:6.0). However, RBC transfusion rates were significantly correlated between CABG and PCI in both crude, 0.48 (P = .005), and adjusted, 0.53 (P = .001), analyses. These findings were consistent when restricting to nonemergent cases (radj = 0.44, P = .001). CONCLUSIONS: Red blood cell transfusion rates were significantly correlated between the CABG and PCI at individual hospitals in Michigan, independent of patient case mix. Future work should explore institutional practice patterns, philosophies, and guidelines for RBC transfusions.

Uncertainty exists regarding the optimal strategy for the management of anemia in the setting of cardiac surgery. We sought to improve our understanding of the role of intra-operative hematocrit (HCT) and transfusions on peri-operative outcomes following cardiac surgery. A total of 18,886 patients undergoing on-pump cardiac surgery were identified from a multi-institutional registry including surgical and perfusion data. Patients were divided into four groups based on their intra-operative nadir HCT (<21 or ≥21) and whether or not they received intra-operative red blood cell (+RBC or -RBC) transfusions. Outcomes were adjusted for the Society of Thoracic Surgeons predicted risk of mortality (PROM), pre-operative HCT, and medical center. Regardless of nadir HCT cohort, those who received a transfusion had higher PROM relative to patients who did not receive a transfusion. The mean PROM was significantly higher among those HCT ≥21 + RBC (5.3%) vs. HCT ≥ 21 - RBC (1.9%), p < .001. Similarly, the PROM was significantly higher among HCT <21 + RBC (5.1%) vs. those HCT <21 - RBC (3.1%), p < .001. Adjusted outcomes demonstrated an increased impact of RBC transfusions on adverse outcomes irrespective of nadir HCT including stroke (p < .001), renal failure (p < .001), prolonged ventilation (p < .001), and mortality (p < .001). This study demonstrates that transfusions have a more profound effect on post-operative cardiac surgery outcomes than anemia.

OBJECTIVES: To evaluate participant characteristics and outcomes during the first 4 years of the Society of Thoracic Surgeons (STS) public reporting program. BACKGROUND: This is the first detailed analysis of a national, voluntary, cardiac surgery public reporting program using STS clinical registry data and National Quality Forum-endorsed performance measures. METHODS: The distributions of risk-adjusted mortality rates, multidimensional composite performance scores, star ratings, and volumes for public reporting versus nonreporting sites were studied during 9 consecutive semiannual reporting periods (2010-2014). RESULTS: Among 8929 unique observations (â¼1000 STS participant centers, 9 reporting periods), 916 sites (10.3%) were classified low performing, 6801 (76.2%) were average, and 1212 (13.6%) were high performing. STS public reporting participation varied from 22.2% to 46.3% over the 9 reporting periods. Risk-adjusted, patient-level mortality rates for isolated coronary artery bypass grafting were consistently lower in public reporting versus nonreporting sites (P value range: <0.001-0.0077). Reporting centers had higher composite performance scores and star ratings (23.2% high performing and 4.5% low performing vs 7.6% high performing and 13.8% low performing for nonreporting sites). STS public reporting sites had higher mean annualized coronary artery bypass grafting volumes than nonreporting sites (169 vs 145, P < 0.0001); high-performing programs had higher mean coronary artery bypass grafting volumes (n = 241) than average (n = 139) or low-performing (n = 153) sites. Risk factor prevalence (except reoperation) and expected mortality rates were generally stable during the study period. CONCLUSIONS: STS programs that voluntarily participate in public reporting have significantly higher volumes and performance. No evidence of risk aversion was found.

BACKGROUND: Impaired functional and cognitive status is an important outcome for older adults undergoing major cardiac surgery. We conducted this pilot study to gauge feasibility of assessing these outcomes longitudinally, from preoperatively up to two time points postoperatively to assess for recovery. METHODS: We interviewed patients aged ≥ 65 y preoperatively and repeated functional and cognitive assessments at 4-6 wk and 4-6 mo postoperatively. Simple unadjusted linear regression was used to test whether baseline measures changed at each follow-up time point. Then we used a longitudinal model to predict postoperative recovery overall, adjusting for comorbidity. RESULTS: A total of 62 patients (age 74.7 ± 5.9) underwent scheduled cardiac surgery. Preoperative activities of daily living (ADL) impairment was associated with poorer functional recovery at 4-6 wk postoperatively with each baseline ADL impairment conferring recovery of 0.5 fewer ADLs (P < 0.05). By 4-6 mo, we could no longer detect a difference in recovery. Preoperative cognition and physical activity were not associated with postoperative changes in these domains. CONCLUSIONS: A preoperative and postoperative evaluation of function and cognition was integrated into the surgical care of older patients. Preoperative impairments in ADLs may be a means to identify patients who might benefit from careful postoperative planning, especially in terms of assistance with self-care during the first 4-6 wk after cardiac surgery.

BACKGROUND: Recent randomized trial data showed fewer strokes with left atrial appendage occlusion (LAAO) following cardiac surgery in patients with atrial fibrillation. We developed a quality initiative to increase LAAO adoption. METHODS: Among 11,099 patients undergoing isolated CABG between January 2019-March 2021 at 33 hospitals in Michigan, those with atrial fibrillation undergoing first-time, on-pump CABG were eligible (n=1,241). A goal LAAO rate of 75% was selected as a quality improvement target through a statewide collaborative. An interrupted time series analysis evaluated the change in LAAO rate before (January-December 2019) versus after (January 2020-March 2021) implementation. RESULTS: Implementation of the quality metric improved LAAO rate from 61% (357/581) before to 79% (520/660) after implementation (p<0.001). Compared to patients not undergoing concomitant LAAO, LAAO patients (71%, 877/1,241) were older, more frequently male, and had a lower STS-PROM (2.9±3.5% vs. 3.7±5.7%, p=0.003), while other baseline characteristics including CHA2DS2-VASc scores were similar. Mean bypass and cross-clamp times were 7 and 6 minutes longer, respectively, in the LAAO group among those who did not undergo concomitant ablation. Operative mortality, major morbidity, blood product administration, and thromboembolic events were similar between groups. Interrupted time series analysis showed a significant increase in LAAO rate after implementation (p=0.009). CONCLUSIONS: LAAO in patients with atrial fibrillation undergoing isolated CABG did not add operative risk versus isolated CABG without LAAO. A statewide quality improvement initiative was successful in increasing the rate of concomitant LAAO and could be further evaluated as a potential quality metric in cardiac surgery.
RESUMEN
OBJECTIVE: Racial disparities in health care have come to the forefront. We hypothesized that Black race was associated with worse preoperative risk, lower repair rates, and worse outcomes among patients who underwent mitral valve surgery. METHODS: All patients who underwent mitral valve repair or replacement with or without coronary artery bypass grafting from 2011 to 2020 in a statewide collaborative database were stratified into 3 racial groups, White, Black, and other. Preoperative characteristics, procedure type, and outcomes were evaluated. RESULTS: A total of 9074 mitral valve operations were performed at 33 centers (Black 1009 [11.1%], White 7862 [86.6%]). Preoperative combined Society of Thoracic Surgeons morbidity and mortality was higher for Black patients (Black 32%, White 22%, other 23%, [P < .001]) because of a greater proportion of diabetes, hypertension, and chronic lung disease. White patients were more likely to undergo mitral repair (White 66%, Black 53.3%, other 57%; P < .001). Operative mortality was similar across racial groups (White 3.7%, Black 4.6%, other 4.5%; P = .36). After adjusting for preoperative factors, mitral etiology, and hospitals, race was not associated with mitral valve repair, complications, or mortality, but Black patients had higher odds of extended care facility utilization and readmission. CONCLUSIONS: Contrary to our hypothesis, there was no difference in the odds of repair or operative mortality across races after accounting for risk and etiology. However, Black patients were more likely to be readmitted after discharge. These findings support a greater focus on reducing disparities in mitral valve surgery.

BACKGROUND: Recent guidelines for the treatment of moderate or severe ischemic mitral regurgitation (IMR) in patients undergoing coronary artery bypass grafting (CABG) have changed. This study assessed the real-world impact of changing guidelines on the management of IMR during CABG over time. We hypothesized that the utilization of mitral valve repair for IMR would decrease over time, whereas mitral valve replacement for severe IMR would increase. METHODS: Patients undergoing CABG in a statewide collaborative database (2011-2020) were stratified by severity of IMR. Trends in mitral valve repair or replacement were evaluated. To account for differences of the patients, propensity score-matched analyses were used to compare patients with and without mitral intervention. RESULTS: A total of 11,676 patients met inclusion criteria, including 1355 (11.6%) with moderate IMR and 390 (3.3%) with severe IMR. The proportion of patients undergoing mitral intervention for moderate IMR decreased over time (2011, 17.7%; 2020, 7.5%; Ptrend = .001), whereas mitral replacement for severe IMR remained stable (2011, 11.1%; 2020, 13.3%; Ptrend = .14). Major morbidity was higher for patients with moderate IMR who underwent mitral intervention (29.1% vs 19.9%; P = .005). In a propensity analysis of 249 well-matched pairs, there was no difference in major morbidity (29.3% with mitral intervention vs 23.7% without; P = .16) or operative mortality (1.2% vs 2.4%; P = .5). CONCLUSIONS: Consistent with recent guideline updates, patients with moderate IMR were less likely to undergo mitral repair. However, the rate of replacement for severe IMR did not change. Mitral intervention during CABG did not increase operative mortality or morbidity.

BACKGROUND: Skilled nursing facility (SNF) care is frequently used after cardiac surgery, but the patterns and determinants of use have not been well understood. The objective of this study was to evaluate determinants and outcomes associated with SNF use after isolated coronary artery bypass grafting. METHODS: A retrospective analysis of Medicare Fee-For-Service claims linked to the Society of Thoracic Surgeons clinical data was conducted on isolated coronary artery bypass grafting patients without prior SNF use in Michigan between 2011 and 2019. Descriptive analysis evaluated the frequency, trends, and variation in SNF use across 33 Michigan hospitals. Multivariable mixed-effects regression was used to evaluate patient-level demographic and clinical determinants of SNF use and its effect on short- and long-term outcomes. RESULTS: In our sample of 8614 patients, the average age was 73.3 years, 70.5% were male, and 7.7% were listed as non-White race. An SNF was utilized by 1920 (22.3%) patients within 90 days of discharge and varied from 3.2% to 58.3% across the 33 hospitals. Patients using SNFs were more likely to be female, older, non-White, with more comorbidities, worse cardiovascular function, a perioperative morbidity, and longer hospital lengths of stay. Outcomes were significantly worse for SNF users, including more frequent 90-day readmissions and emergency department visits and less use of home health and rehabilitation services. SNF users had higher risk-adjusted hazard of mortality (hazard ratio, 1.41 [95% CI, 1.26-1.57]; P<0.001) compared with non-SNF users and had 2.7-percentage point higher 5-year mortality rate in a propensity-matched cohort of patients (18.1% versus 15.4%; P<0.001). CONCLUSIONS: The use of SNF care after isolated coronary artery bypass grafting was frequent and variable across Michigan hospitals and associated with worse risk-adjusted outcomes. Standardization of criteria for SNF use may reduce variability among hospitals and ensure appropriateness of use.

The Michigan Society of Thoracic and Cardiovascular Surgeons (MSTCVS), a pioneer in initiating and nurturing quality improvement strategies in statewide cardiothoracic surgery, has been running the Quality Collaborative (MSTCVS-QC) program since 2001. This initiative has significantly grown over the years, facilitating at least 4 in-person meetings annually. It actively engages cardiac and general thoracic surgeons, data managers and researchers from all 32 non-federally funded cardiothoracic surgery sites across Michigan. Broadening its influence on joint learning and clinical outcomes, the MSTCVS-QC formed a strategic partnership with Blue Cross Blue Shield of Michigan, the state's largest private insurer, to further promote its initiatives. The MSTCVS-QC, operating from a dedicated QC centre employs an STS-associated database with additional aspects for data collection and analysis. The QC centre also organizes audits, facilitates collaborative meetings, disseminates surgical outcomes and champions the development and implementation of quality improvement initiatives related to cardiothoracic surgery in Michigan. Recognizing the MSTCVS-QC's successful efforts in advancing quality improvement, the European Association for Cardiothoracic Surgery (EACTS) introduced a fellowship program in 2018, facilitated through the EACTS Francis Fontan Fund (FFF). This program allows early-career academic physicians to spend 4-6 months with the MSTCVS-QC team in Ann Arbor. This article chronicles the evolution and functionality of the MSTCVS-QC, enriched by the experiences of the inaugural 4 EACTS/FFF fellows. Our objective is to emphasize the critical importance of fostering a culture of quality improvement and patient safety in the field of cardiothoracic surgery with open discussion of audited, high-quality data points. This principle, while implemented locally, has implications and value extending far beyond Europe, resonating globally.

Venous thromboembolism (VTE) carries significant morbidity and mortality and affects a large portion of hospitalized patients. VTE prophylaxis is rated by the Agency for Healthcare Research and Quality as the most effective of 79 patient safety practices it assessed in 2001. Since 1997, Blue Cross Blue Shield of Michigan/Blue Care Network (BCBSM/BCN) have partnered with Michigan hospitals and providers in statewide registry-based collaborative quality improvement initiatives (CQI) aimed at improving the safety and quality of surgical and medical care; many of these collaborative have a particular focus on VTE prevention. The CQIs are uniquely structured to catalyze hospitals and practitioners to become self-optimizing. In this review, we describe the model BCBSM/BCN and participating Michigan hospitals have developed to improve the prevention and diagnosis of VTE for patients in the state of Michigan.

Although regional and national registries exist to measure and report performance of cardiac surgical programs, few registries exist dedicated to the practice of cardiopulmonary bypass (CPB). We developed and implemented a cardiovascular perfusion registry (Perfusion Measures and outcomes [PERForm] Registry) within the structure of the Michigan Society of Thoracic and Cardiovascular Surgeons (MSTCVS) to improve our understanding of the practice of CPB. The PERForm Registry comprises data elements describing the practice of CPB. Fourteen medical centers within MSTCVS have voluntarily reported these data on procedures in which CPB is used. We validated the case count among procedures performed between January 1, 2011 to December 31, 2011, and validated the values among 20 fields at three medical centers. We queried database managers at all 14 medical centers to identify the infrastructure that contributed to best overall data collection performance. We found that 98% of all records submitted to the PERForm and 95% of those submitted to the Society of Thoracic Surgeons (STS) matched. We found quite favorable agreement in our audit of select fields (95.8%). Those centers with the most favorable performance in this validation study were more likely to use electronic data capture, have a perfusionist as the STS database manager, and have involvement of the STS database manager in the PERForm or STS databases. We successfully and accurately collected data concerning cardiovascular perfusion among 14 institutions in conjunction with the MSTCVS. Future efforts will focus on expanding data collection to all MSTCVS participating institutions as well as more broadly outside of Michigan.

BACKGROUND: Prior work has established that high socioeconomic deprivation is associated with worse short- and long-term outcomes for patients undergoing coronary artery bypass grafting (CABG). The relationship between socioeconomic status and 90-day episode spending is poorly understood. In this observational cohort analysis, we evaluated whether socioeconomically disadvantaged patients were associated with higher expenditures during 90-day episodes of care after isolated CABG. METHODS: We linked clinical registry data from 8728 isolated CABG procedures from January 1, 2012, to December 31, 2018, to Medicare fee-for-service claims data. Our primary exposure variable was patients in the top decile of the Area Deprivation Index. Linear regression was used to compare risk-adjusted, price-standardized 90-day episode spending for deprived against nondeprived patients as well as component spending categories: index hospitalization, professional services, post acute care, and readmissions. RESULTS: A total of 872 patients were categorized as being in the top decile. Mean 90-day episode spending for the 8728 patients in the sample was $55 258 (SD, $26 252). Socioeconomically deprived patients had higher overall 90-day spending compared with nondeprived patients ($61 579 vs $54 557; difference, $3003; P = .001). Spending was higher in socioeconomically deprived patients for index hospitalizations (difference, $1284; P = .005), professional services (difference, $379; P = .002), and readmissions (difference, $1188; P = .008). Inpatient rehabilitation was the only significant difference in post-acute care spending (difference, $469; P = .011). CONCLUSIONS: Medicare spending was higher for socioeconomically deprived CABG in Michigan, indicating systemic disparities over and above patient demographic factors.

BACKGROUND: Cardiovascular outcomes are worse among individuals from areas with limited socioeconomic resources. This study evaluated the relationship between high socioeconomic deprivation and isolated coronary artery bypass grafting (CABG) outcomes. METHODS: We linked statewide Society of Thoracic Surgeons Adult Cardiac Surgery Database data to Medicare Fee-for-Service records for 10 423 Michigan residents undergoing isolated CABG between January 2012 and December 2018. High socioeconomic deprivation was defined as residing in the highest decile of the ZIP Code-level area deprivation index (ADI). Multivariable logistic regression estimated the relationship between top ADI decile and major morbidity, in-hospital mortality, and operative mortality. Survival analyses evaluated long-term survival comparing patients in the top vs not in the top ADI decile. RESULTS: A total of 1036 patients were in the top decile of ADI (ADI >82.4), and they were more likely to be female, Black, and have a higher predicted risk of mortality. Patients in the top ADI decile had significantly higher rates of major morbidity (17.4% vs 11.4%; adjusted odds ratio, 1.26; 95% CI, 1.04-1.54; P = .021) and in-hospital mortality (3.2% vs 1.3%, adjusted odds ratio, 1.84; 95% CI, 1.18-2.86, P = .007) but not operative mortality. The adjusted hazard of mortality was 16% higher for patients residing in the top ADI decile (95% CI, 1.01-1.33; P = .032). CONCLUSIONS: Isolated CABG patients residing in the highest areas of socioeconomic deprivation differed with respect to demographic and clinical characteristics and experienced worse short- and long-term outcomes compared with those not in the top ADI decile.

OBJECTIVE: The study objective was to evaluate whether 5-m gait speed, an established marker of frailty, is associated with postoperative events after elective proximal aortic surgery. METHODS: We performed a retrospective review of 435 patients aged more than 60 years who underwent elective proximal aortic surgery, defined as surgery on the aortic root, ascending aorta, or aortic arch through median sternotomy. Patients completed a 5-m gait speed test within 30 days before surgery. We evaluated the association between categoric (slow, ≤0.83 m/s and normal, >0.83 m/s) and continuous gait speed and the likelihood of experiencing the composite outcome before and after adjustment for European System for Cardiac Operative Risk Evaluation II. The composite outcome included in-hospital mortality, renal failure, prolonged ventilation, and discharge location. Secondary outcomes were 1-year mortality and 5-year survival. RESULTS: Of the study population, 30.3% (132/435) were categorized as slow. Slow walkers were significantly more likely to have in-hospital mortality, prolonged ventilation, and renal failure, and were less likely to be discharged home (all P < .05). The composite outcome was 2 times more likely to occur for slow walkers (gait speed categoric adjusted odds ratio, 2.08; 95% confidence interval, 1.27-3.40; P = .004). Moreover, a unit (1 m/s) increase in gait speed (continuous) was associated with 73% lower risk of experiencing the composite outcome (odds ratio, 0.27; 95% confidence interval, 0.11-0.68; P = .006). CONCLUSIONS: Slow gait speed is a preoperative indicator of risk for postoperative events after elective proximal aortic surgery. Gait speed may be an important tool to complement existing operative risk models, and its application may identify patients who may benefit from presurgical and postsurgical rehabilitation.

BACKGROUND: Whether all patients will require an opioid prescription after cardiac surgery is unknown. We performed a multicenter analysis to identify patient predictors of not receiving an opioid prescription at the time of discharge home after cardiac surgery. METHODS: Opioid-naïve patients undergoing coronary artery bypass grafting and/or valve surgery through a sternotomy at 10 centers from January to December 2019 were identified retrospectively from a prospectively maintained data set. Opioid-naïve was defined as not taking opioids at the time of admission. The primary outcome was discharge without an opioid prescription. Mixed-effects logistic regression was performed to identify predictors of discharge without an opioid prescription, and postdischarge opioid prescribing was monitored to assess patient tolerance of discharge without an opioid prescription. RESULTS: Among 1924 eligible opioid-naïve patients, mean age was 64 ± 11 years, and 25% were women. In total, 28% of all patients were discharged without an opioid prescription. On multivariable analysis, older age, longer length of hospital stay, and undergoing surgery during the last 3 months of the study were independent predictors of discharge without an opioid prescription, whereas depression, non-Black and non-White race, and using more opioid pills on the day before discharge were independent predictors of receiving an opioid prescription. Among patients discharged without an opioid prescription, 1.8% (10 of 547) were subsequently prescribed an opioid. CONCLUSIONS: Discharging select patients without an opioid prescription after cardiac surgery appears well tolerated, with a low incidence of postdischarge opioid prescriptions. Increasing the number of patients discharged without an opioid prescription may be an area for quality improvement.

BACKGROUND: The relationship between institutional volume and operative mortality after surgical aortic valve replacement (SAVR) remains unclear. METHODS: From January 2013 to June 2018, 234 556 patients underwent isolated SAVR (n = 144 177) or SAVR with coronary artery bypass grafting (CABG) (n = 90 379) within the Society of Thoracic Surgeons Adult Cardiac Surgery Database. The association between annualized SAVR volume (group 1 [1-25 SAVRs], group 2 [26-50 SAVRs], group 3 [51-100 SAVRs], and group 4 [>100 SAVRs]) and operative mortality and composite major morbidity or mortality was assessed. Random effects models were used to evaluate whether historical (2013-2015) SAVR volume or risk-adjusted outcomes explained future (2016-2018) risk-adjusted outcomes. RESULTS: The annualized median number of SAVRs per site was 35 (interquartile range, 22-59; isolated aortic valve replacement [AVR], 20; AVR with CABG, 13). Among isolated SAVR cases, the mean operative mortality and composite morbidity or mortality were 1.5% and 9.7%, respectively, at the highest-volume sites (group 4), with significantly higher rates among progressively lower-volume groups (P trend < .001). After adjustment, lower-volume centers had increased odds of operative mortality (group 1 vs group 4 [reference]: adjusted odds ratio [AOR] for SAVR, 2.24 [95% CI, 1.91-2.64]; AOR for SAVR with CABG, 1.96 [95% CI, 1.67-2.30]) and major morbidity or mortality (AOR for SAVR, 1.53 [95% CI, 1.39-1.69]; AOR for SAVR with CABG, 1.46 [95% CI, 1.32-1.61]) compared with the highest-volume institutions. Substantial variation in outcomes was observed across hospitals within each volume category, and prior outcomes explained a greater proportion of hospital operative outcomes than did prior volume. CONCLUSIONS: Operative outcomes after SAVR with or without CABG is inversely associated with institutional procedure volumes; however, prior outcomes are more predictive of future outcomes than is prior volume. Given the excellent outcomes observed at many lower-volume hospitals, procedural outcomes may be preferable to procedural volumes as a quality metric.
