Objective: Cumulative, probability-based metrics are regularly used to measure quality in professional sports, but these methods have not been applied to health care delivery. These techniques have the potential to be particularly useful in describing surgical quality, where case volume is variable and outcomes tend to be dominated by statistical "noise." The established statistical technique used to adjust for differences in case volume is reliability-adjustment, which emphasizes statistical "signal" but has several limitations. We sought to validate a novel measure of surgical quality based on earned outcomes methods (deaths above average [DAA]) against reliability-adjusted mortality rates, using abdominal aortic aneurysm (AAA) repair outcomes to illustrate the measure's performance., Methods: Earned outcomes methods were used to calculate the outcome of interest for each patient: DAA. Hospital-level DAA was calculated for non-ruptured open AAA repair and endovascular aortic repair (EVAR) in the Vascular Quality Initiative database from 2016 to 2019. DAA for each center is the sum of observed - predicted risk of death for each patient; predicted risk of death was calculated using established multivariable logistic regression modeling. Correlations of DAA with reliability-adjusted mortality rates and procedure volume were determined. Because an accurate quality metric should correlate with future results, outcomes from 2016 to 2017 were used to categorize hospital quality based on: (1) risk-adjusted mortality; (2) risk- and reliability-adjusted mortality; and (3) DAA. The best performing quality metric was determined by comparing the ability of these categories to predict 2018 to 2019 risk-adjusted outcomes., Results: During the study period, 3734 patients underwent open repair (106 hospitals), and 20,680 patients underwent EVAR (183 hospitals). DAA was closely correlated with reliability-adjusted mortality rates for open repair (r = 0.94; P < .001) and EVAR (r = 0.99; P < .001). DAA also correlated with hospital case volume for open repair (r = -.54; P < .001), but not EVAR (r = 0.07; P = .3). In 2016 to 2017, most hospitals had 0% mortality (55% open repair, 57% EVAR), making it impossible to evaluate these hospitals using traditional risk-adjusted mortality rates alone. Further, zero mortality hospitals in 2016 to 2017 did not demonstrate improved outcomes in 2018 to 2019 for open repair (3.8% vs 4.6%; P = .5) or EVAR (0.8% vs 1.0%; P = .2) compared with all other hospitals. In contrast to traditional risk-adjustment, 2016 to 2017 DAA evenly divided centers into quality quartiles that predicted 2018 to 2019 performance with increased mortality rate associated with each decrement in quality quartile (Q1, 3.2%; Q2, 4.0%; Q3, 5.1%; Q4, 6.0%). There was a significantly higher risk of mortality at worst quartile open repair hospitals compared with best quartile hospitals (odds ratio, 2.01; 95% confidence interval, 1.07-3.76; P = .03). Using 2016 to 2019 DAA to define quality, highest quality quartile open repair hospitals had lower median DAA compared with lowest quality quartile hospitals (-1.18 DAA vs +1.32 DAA; P < .001), correlating with lower median reliability-adjusted mortality rates (3.6% vs 5.1%; P < .001)., Conclusions: Adjustment for differences in hospital volume is essential when measuring hospital-level outcomes. Earned outcomes accurately categorize hospital quality and correlate with reliability-adjustment but are easier to calculate and interpret. From 2016 to 2019, highest quality open AAA repair hospitals prevented >40 perioperative deaths compared with the average hospital, and >80 perioperative deaths compared with lowest quality hospitals., Competing Interests: Disclosures None., (Copyright © 2024 Society for Vascular Surgery.

Based on a voluntary registry, founded by the German Society for Thoracic and Cardiovascular Surgery (DGTHG) in 1980, a well-defined but limited dataset of all cardiac and vascular surgery procedures performed in 77 German heart surgery departments is reported annually. For the year 2023, a total of 168,841 procedures were submitted to the registry. Of these operations, 100,606 are defined as heart surgery procedures in a classical sense. The unadjusted in-hospital survival rate for the 28,996 isolated coronary artery bypass grafting procedures (relationship on-/off-pump 2.8:1) was 97.6%; 97.7% for the 39,859 isolated heart valve procedures (23,727 transcatheter interventions included); and 99.2% for 19,699 pacemaker/implantable cardioverter defibrillator procedures. Concerning short and long-term mechanical circulatory support, a total of 2,982 extracorporeal life support/extracorporeal membrane oxygenation implantations and 772 ventricular assist device implantations (left/right ventricular assist device, BVAD, total artificial heart) were reported. In 2023, 324 isolated heart transplantations, 248 isolated lung transplantations, and 2 combined heart-lung transplantations were performed. This annually updated registry of the DGTHG represents nonrisk adjusted voluntary public reporting and encompasses acute data for nearly all heart surgical procedures in Germany. It constitutes trends in heart medicine and represents a basis for quality management (e.g., benchmark) for all participating institutions., Competing Interests: None declared., (Thieme.

Background: Endovascular aortic aneurysm repair (EVAR) has had a dynamic impact on abdominal aortic aneurysm (AAA) care, often supplanting open AAA repair (OAR). Accordingly, US AAA management is often highlighted by disparities in patient selection and guideline compliance. The purpose of this analysis was to define secular trends in AAA care., Methods: The Society for Vascular Surgery Vascular Quality Initiative was queried for all EVARs and OARs (2011-2021). End points included procedure utilization, change in mortality, patient risk profile, Society for Vascular Surgery-endorsed diameter compliance, off-label EVAR use, cross-clamp location, blood loss, in-hospital complications, and post-EVAR surveillance missingness. Linear regression was used without risk adjustment for all end points except for mortality and complications, for which logistic regression with risk adjustment was used., Results: In all, 66 609 EVARs (elective, 85% [n=55 805] and nonelective, 15% [n=9976]) and 13 818 OARs (elective, 70% [n=9706] and nonelective, 30% [n=4081]) were analyzed. Elective EVAR:OAR ratios were increased (0.2 per year [95% CI, 0.01-0.32]), while nonelective ratios were unchanged. Elective diameter threshold noncompliance decreased for OAR (24%→17%; P =0.01) but not EVAR (mean, 37%). Low-risk patients increasingly underwent elective repairs (EVAR, +0.4%per year [95% CI, 0.2-0.6]; OAR, +0.6 points per year [95% CI, 0.2-1.0]). Off-label EVAR frequency was unchanged (mean, 39%) but intraoperative complications decreased (0.5% per year [95% CI, 0.2-0.9]). OAR complexity increased reflecting greater suprarenal cross-clamp rates (0.4% per year [95% CI, 0.1-0.8]) and blood loss (33 mL/y [95% CI, 19-47]). In-hospital complications decreased for elective (0.7% per year [95% CI, 0.4-0.9]) and nonelective EVAR (1.7% per year [95% CI, 1.1-2.3]) but not OAR (mean, 42%). A 30-day mortality was unchanged for both elective OAR (mean, 4%) and EVAR (mean, 1%). Among nonelective OARs, an increase in both 30-day (0.8% per year [95% CI, 0.1-1.5]) and 1-year mortality (0.8% per year [95% CI, 0.3-1.6]) was observed. Postoperative EVAR surveillance acquisition decreased (67%→49%), while 1-year mortality among patients without imaging was 4-fold greater (9.2% versus imaging, 2.0%; odds ratio, 4.1 [95% CI, 3.8-4.3]; P <0.0001)., Conclusions: There has been an increase in EVAR and a corresponding reduction in OAR across the United States, despite established concerns surrounding guideline adherence, reintervention, follow-up, and cost. Although EVAR morbidity has declined, OAR complication rates remain unchanged and unexpectedly high. Opportunities remain for improving AAA care delivery, patient and procedure selection, guideline compliance, and surveillance., Competing Interests: Disclosures Dr Scali is the chair of the Society for Vascular Surgery Vascular Quality Initiative Patient Safety Organization EVAR Registry (unpaid position).

Background: Calls for minimum case thresholds to guide surgeon credentialing paradigms are increasing in contemporary practice. To date, the volume-outcome relationship and the role of surgeon experience as a proxy for quality have remained primarily focused on nonvascular extirpative surgery and aneurysm repair. However, it is unclear whether these data can be rightly extrapolated to predict lower extremity bypass (LEB) outcomes. Thus, the purpose of the present study was to examine whether the annualized case volume vs surgeon experience is more consequential in predicting for successful LEB reconstruction., Methods: A total of 25,852 procedures with sufficient 1-year follow-up data from the Society for Vascular Surgery Vascular Quality Initiative infrainguinal bypass registry (2003-2019) were reviewed for chronic limb threatening ischemia among patients undergoing infrageniculate reconstruction. The procedures were categorized according to surgeon years of practice experience at surgery (ie, 0-5, 6-10, 11-15, >15 years) and the number of LEB procedures performed by the surgeon during the year of surgery (volume quartiles: 1-8, 9-14, 15-21, and >21). Mixed effects logistic and Cox regression models were used to assess the effects of experience, volume, and their interaction on outcomes., Results: Increasing practice experience was more significantly associated with a reduction of in-hospital complications (odds ratio, 0.97; 95% confidence interval [CI], 0.96-0.99; P = .002) and the risk of major adverse limb events (odds ratio, 0.94; 95% CI, 0.92-0.97; P < .0001) compared with the volume. Increasing experience and volume were both associated with increased freedom from thrombosis (hazard ratio, 0.95; 95% CI, 0.93-0.98; P = .001). In contrast, neither experience nor volume had any significant association with early mortality. However, a higher volume was associated with diminished long-term survival (hazard ratio, 1.04; 95% CI, 1.0-1.1; P = .01). The most experienced surgeons (>15 years' experience) were significantly more likely to perform LEB for rest pain (P < .0001). No significant differences were found in the bypass rates among patients with tissue loss. The most experienced and highest volume surgeons were more likely to use an autogenous and/or composite conduit, in situ reconstruction, and/or pedal targets (P < .05). Similarly, more experienced and higher volume surgeons had less blood loss and shorter procedure times (P < .0001). Overall, the most experienced surgeons (>15 years' experience) were significantly more likely to have a higher volume with a diminished risk for all LEB outcomes., Conclusions: Surgeon experience appears to have the most important role in predicting for overall LEB performance with improved in-hospital outcomes and major adverse limb events. The more experienced surgeons performed more complex reconstructions with fewer complications. These findings have significant clinical and educational implications as our most experienced surgeons approach retirement. Mentorship strategies to facilitate ongoing technical development among less experienced surgeons are imperative to sustain optimal limb salvage outcomes and have significant ramifications regarding expectations for regulatory and credentialing paradigms., (Copyright © 2021 Society for Vascular Surgery.

Background: Hospital-specific template matching is a newer method of hospital performance measurement that may be fairer than regression-based benchmarking. However, it has been tested in only limited research settings., Objective: The objective of this study was to test the feasibility of hospital-specific template matching assessments in the Veterans Affairs (VA) health care system and determine power to detect greater-than-expected 30-day mortality., Research Design: Observational cohort study with hospital-specific template matching assessment. For each VA hospital, the 30-day mortality of a representative subset of hospitalizations was compared with the pooled mortality from matched hospitalizations at a set of comparison VA hospitals treating sufficiently similar patients. The simulation was used to determine power to detect greater-than-expected mortality., Subjects: A total of 556,266 hospitalizations at 122 VA hospitals in 2017., Measures: A number of comparison hospitals identified per hospital; 30-day mortality., Results: Each hospital had a median of 38 comparison hospitals (interquartile range: 33, 44) identified, and 116 (95.1%) had at least 20 comparison hospitals. In total, 8 hospitals (6.6%) had a significantly lower 30-day mortality than their benchmark, 5 hospitals (4.1%) had a significantly higher 30-day mortality, and the remaining 109 hospitals (89.3%) were similar to their benchmark. Power to detect a standardized mortality ratio of 2.0 ranged from 72.5% to 79.4% for a hospital with the fewest (6) versus most (64) comparison hospitals., Conclusions: Hospital-specific template matching may be feasible for assessing hospital performance in the diverse VA health care system, but further refinements are needed to optimize the approach before operational use. Our findings are likely applicable to other large and diverse multihospital systems., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objectives: A core set of outcomes have been identified and published, which are essential to include in all clinical research evaluating the use of extracorporeal membrane oxygenation in critically ill patients, particularly regarding safety and adverse events. The purpose of this international modified Delphi study was to determine which measurement tools and the timing of measurement should be selected for the core outcome set for research evaluating patients receiving extracorporeal membrane oxygenation., Design: This was a two-round international, multidisciplinary web-based, modified Delphi study., Patients: Participants were identified from the International Extracorporeal Membrane Oxygenation Network and the Extracorporeal Life Support Organization, including consumers, multidisciplinary clinicians, researchers and industry partners., Measurements: Measurement tools and the timing of measurement were identified from a systematic review of the literature and clinical trials registrations. The primary outcome was the percentage of respondents who completed each survey and indicated that a measurement tool as well as the timing of the measurement should "always" be included in a core outcome set., Main Results: Participant response rates were 46 of 65 (71%) and 40 of 46 (87%) for rounds one and two, respectively, with participants representing, researchers, consumers, and industry partners from 15 countries over five continents. Seven measurement tools were identified for the core outcome set of patients on extracorporeal membrane oxygenation., Conclusions: This study has identified appropriate measurement instruments and the timing of measurement to include in the core outcome set for research evaluating patients receiving extracorporeal membrane oxygenation.

Background: Perioperative outcomes of children depend on the skill and expertise in managing pediatric patients, as well as integration of surgical, anesthesiology, and medical teams. We compared the types of pediatric patients and inpatient surgical procedures performed in low- versus higher-volume hospitals throughout the United States., Methods: Retrospective analysis of 323,258 hospitalizations with an operation for children age 0 to 17 years in 2857 hospitals included in the Agency for Healthcare Research and Quality (AHRQ) Kids' Inpatient Database (KID) 2016. Hospitals were categorized by their volume of annual inpatient surgical procedures. Specific surgeries were distinguished with the AHRQ Clinical Classification System. We assessed complex chronic conditions (CCCs) using Feudtner and Colleagues' system., Results: The median annual volume of pediatric inpatient surgeries across US hospitals was 8 (interquartile range [IQR], 3-29). The median volume of inpatient surgeries for children with a CCC was 4 (IQR, 1-13). Low-volume hospitals performed significantly fewer types of surgeries (median 2 vs 131 types of surgeries in hospitals with 1-24 vs ≥2000 volumes). Appendectomy and fixation of bone fracture were among the most common surgeries in low-volume hospitals. As the volume of surgical procedures increased from 1 to 24 to ≥2000, the percentage of older children ages 11 to 17 years decreased (70.9%-32.0% [P < .001]) and the percentage of children with a CCC increased (11.2%-60.0% [P < .001])., Conclusions: Thousands of US hospitals performed inpatient surgeries on few pediatric patients, including those with CCCs who have the highest risk of perioperative morbidity and mortality. Evaluation of perioperative decision making, workflows, and pediatric clinicians in low- and higher-volume hospitals is warranted., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

Introduction: The novel coronavirus SARS-CoV-2 (COVID-19) has spread rapidly since it was identified. We sought to understand its effects on vascular surgery practices stratified by VASCON surgical readiness level and determine how these effects have changed during the course of the pandemic., Methods: All members of the Vascular and Endovascular Surgery Society were sent electronic surveys questioning the effects of COVID-19 on their practices in the early pandemic in April (EP) and four months later in the pandemic in August (LP) 2020., Results: Response rates were 206/731 (28%) in the EP group and 108/731 (15%) in the LP group (P < 0.0001). Most EP respondents reported VASCON levels less than 3 (168/206,82%), indicating increased hospital limitations while 6/108 (6%) in the LP group reported this level (P < 0.0001). The EP group was more likely to report a lower VASCON level (increased resource limitations), and decreased clinic, hospital and emergency room consults. Despite an increase of average cases/week to pre-COVID-19 levels, 46/108 (43%) of LP report continued decreased compensation, with 57% reporting more than 10% decrease. Respondents in the decreased compensation group were more likely to have reported a VASCON level 3 or lower earlier in the pandemic (P = 0.018). 91/108(84%) of LP group have treated COVID-19 patients for thromboembolic events, most commonly acute limb ischemia (76/108) and acute DVT (76/108). While the majority of respondents are no longer delaying the vascular surgery cases, 76/108 (70%) feel that vascular patient care has suffered due to earlier delays, and 36/108 (33%) report a backlog of cases caused by the pandemic., Conclusions: COVID-19 had a profound effect on vascular surgery practices earlier in the pandemic, resulting in continued detrimental effects on the provision of vascular care as well as compensation received by vascular surgeons., (Copyright © 2021.

Objectives: Most data on telestroke utilization come from single academic hub-and-spoke telestroke networks. Our objective was to describe characteristics of telestroke consultations among a national sample of telestroke sites on one of the most commonly used common vendor platforms, prior to the COVID-19 public health emergency., Materials and Methods: A commercial telestroke vendor provided data on all telestroke consultations by two specialist provider groups from 2013-2019. Kendall's τ β nonparametric test was utilized to assess time trends. Generalized linear models were used to assess the association between hospital consult utilization and alteplase use adjusting for hospital characteristics., Results: Among 67,736 telestroke consultations to 132 spoke sites over the study period, most occurred in the emergency department (90%) and for stroke indications (final clinical diagnoses: TIA 13%, ischemic stroke 39%, hemorrhagic stroke 2%, stroke mimics 46%). Stroke severity was low (median NIHSS 2, IQR 0-6). Alteplase was recommended for 23% of ischemic stroke patients. From 2013 to 2019, times from ED arrival to NIHSS, CT scan, imaging review, consult, and alteplase administration all decreased (p<0.05 for all), while times from consult start to alteplase recommendation and bolus increased (p<0.01 for both). Transfer was recommended for 8% of ischemic stroke patients. Number of patients treated with alteplase per hospital increased with increasing number of consults and hospital size and was also associated with US region in unadjusted and adjusted analyses. Longer duration of hospital participation in the network was associated with shorter hospital median door-to-needle time for alteplase delivery (39 min shorter per year, p=0.04)., Conclusions: Among spoke sites using a commercial telestroke platform over a seven-year time horizon, times to consult start and alteplase bolus decreased over time. Similar to academic networks, duration of telestroke participation in this commercial network was associated with faster alteplase delivery, suggesting practice improves performance., Competing Interests: Declaration of Competing Interest KSZ, RS, AM have no disclosures to report.

In an effort to further improve surgical outcomes in patients with acute type A aortic dissection (ATAD), the Canadian Thoracic Aortic Collaborative (CTAC), with the support of the Canadian Society of Cardiac Surgeons (CSCS), endeavoured to develop quality indicators (QIs) for the management of patients with ATAD. After 2 successive consultations with the CTAC membership, 11 QIs were selected and separated into 5 broad categories: preoperative (time from presentation to diagnosis, time from presentation to the operating room), intraoperative (use of hypothermic circulatory arrest and antegrade cerebral perfusion), 30-day outcomes (30-day rates of all-cause mortality, 30-day rates of new postoperative stroke), 1-year outcomes (1-year rates of follow-up imaging, 1-year rates of all-cause mortality, and 1-year rates of surgical reintervention), and institutional (institutional surgical volumes, individual surgical volumes, and presence of institutional aortic disease teams). The purpose of this article is to describe the process by which QIs for the management of ATAD were developed and the feasibility by which they may be collected using existing clinical and administrative data sources. Furthermore, we demonstrate how they may be used to evaluate success following surgery for repair of ATAD and ultimately improve clinical outcomes., (Crown Copyright © 2021.

Objective: Despite published guidelines and data for Medicare patients, it is uncertain how younger patients with intermittent claudication (IC) are treated. Additionally, the degree to which treatment patterns have changed over time with the expansion of endovascular interventions and outpatient centers is unclear. Our goal was to characterize IC treatment patterns in the commercially insured non-Medicare population., Methods: The IBM MarketScan Commercial Database, which includes more than 8 billion US commercial insurance claims, was queried for patients newly diagnosed with IC from 2007 to 2016. Patient demographics, medication profiles, and open/endovascular interventions were evaluated. Time trends were modeled using simple linear regression and goodness-of-fit was assessed with coefficients of determination (R 2 ). A patient-centered cohort sample and a procedure-focused dataset were analyzed., Results: Among 152,935,013 unique patients in the database, there were 300,590 patients newly diagnosed with IC. The mean insurance coverage was 4.4 years. The median patients age was 58 years and 56% of patients were male. The prevalence of statin use was 48% among patients at the time of IC diagnosis and increased to 52% among patients after one year from diagnosis. Interventions were performed in 14.3%, of whom 20% and 6% underwent two or more and three or more interventions, respectively. The median time from diagnosis to intervention decreased from 230 days in 2008 days to 49 days in 2016 (R 2  = 0.98). There were 16,406 inpatient and 102,925 ambulatory interventions for IC over the study period. Among ambulatory interventions, 7.9% were performed in office-based/surgical centers. The proportion of atherectomies performed in the ambulatory setting increased from 9.7% in 2007 to 29% in 2016 (R 2  = 0.94). In office-based/surgical centers, 57.6% of interventions for IC used atherectomy in 2016. Atherectomy was used in ambulatory interventions by cardiologists in 22.6%, surgeons in 15.2%, and radiologists in 13.6% of interventions. Inpatient atherectomy rates remained stable over the study period. Open and endovascular tibial interventions were performed in 7.9% and 7.8% of ambulatory and inpatient IC interventions, respectively. Tibial bypasses were performed in 8.2% of all open IC interventions., Conclusions: There has been shorter time to intervention in the treatment of younger, commercially insured patients with IC, with many receiving multiple interventions. Statin use was low. Ambulatory procedures, especially in office-based/surgical centers, increasingly used atherectomy, which was not observed in inpatient settings., (Copyright © 2021 Society for Vascular Surgery.

Background: Esophagogastroduodenoscopy (EGD) is commonly used diagnostic method with no widely accepted quality measure. We assessed quality indicator-composite detection rate (CDR)-consisting of detection of at least one of the following: cervical inlet patch, gastric polyp and post-ulcer duodenal bulb deformation. The aim of the study was to validate CDR according to detection rate of upper gastrointestinal neoplasms (UGN)., Methods: It was a multicenter, prospective, observational study conducted from January 2019 to October 2019. The endoscopic reports from 2896 symptomatic patients who underwent diagnostic EGD were analyzed. The EGDs were performed in three endoscopy units located in tertiary university hospital, private outpatient clinic and local hospital., Results: 64 UGNs were detected. The mean CDR was 21.9%. The CDR correlated with UGN detection rate (R = 0.49, p = 0.045). Based on CDR quartiles, operators were divided into group 1 with CDR < 10%, group 2 with CDR 10-17%, group 3 with CDR 17.1-26%, and group 4 with CDR > 26%. Detection rate of UGN was significantly higher in the group 4 in comparison to group 1 (OR 4.4; 95% CI 2.2 - 9.0). In the multivariate regression model, patient age, male gender and operator's CDR > 26% were independent risk factors of UGN detection (OR 1.03; 95% CI 1.01 - 1.05, OR 2; 95% CI 1.2 - 3.5, and OR 5.7 95% CI 1.5 - 22.3, respectively)., Conclusions: The CDR is associated with the detection of upper gastrointestinal neoplasms. This parameter may be a useful quality measure of EGD to be applied in general setting., (© 2021. The Author(s).)

Background and Purpose: Delayed evaluation of stroke may contribute to COVID-19 pandemic-related morbidity and mortality. This study evaluated patient characteristics, process measures and outcomes associated with the decline in stroke presentation during the early pandemic., Methods: Volumes of stroke presentations, intravenous thrombolytic administrations, and mechanical thrombectomies from 52 hospitals from January 1-June 30, 2020 were analyzed with piecewise linear regression and linear spline models. Univariate analysis compared pandemic (case) and pre-pandemic (control) groups defined in relation to the nadir of daily strokes during the study period. Significantly different patient characteristics were further evaluated with logistic regression, and significantly different process measures and outcomes were re-analyzed after propensity score matching., Results: Analysis of 7,389 patients found daily stroke volumes decreased 0.91/day from March 12-26 (p < 0.0001), reaching a nadir 35.0% less than expected, and increased 0.15 strokes/day from March 27-June 23, 2020 (p < 0.0001). Intravenous thrombolytic administrations decreased 3.3/week from February 19-March 31 (p = 0.0023), reaching a nadir 33.4% less than expected, and increased 1.4 administrations/week from April 1-June 23 (p < 0.0001). Mechanical thrombectomy volumes decreased by 1.5/week from February 19-March 31, 2020 (p = 0.0039), reaching a nadir 11.3% less than expected. The pandemic group was more likely to ambulate independently at baseline (p = 0.02, OR = 1.60, 95% CI = 1.08-2.42), and less likely to present with mild stroke symptoms (NIH Stroke Scale ≤ 5; p = 0.04, OR = 1.01, 95% CI = 1.00-1.02). Process measures and outcomes of each group did not differ, including door-to-needle time, door-to-puncture time, and successful mechanical thrombectomy rate., Conclusion: Stroke presentations and acute interventions decreased during the early COVID-19 pandemic, at least in part due to patients with lower baseline functional status and milder symptoms not seeking medical care. Public health messaging and initiatives should target these populations., Competing Interests: Declaration of Competing Interest ANW, KSA, SJW, TM, EFL, SG, KDK, MPL, JTM, KA – None; DHS – consultant (Medtronic, Stryker, Microvention, Phenox), speaker and proctor (Medtronic); DPG – consultant (iSchemaView, Medtronic, Siemens Healthineers A.G.)., (Copyright © 2020.

Background: COVID-19 has impacted acute stroke care with several reports showing worldwide drops in stroke caseload during the pandemic. We studied the impact of COVID-19 on acute stroke care in our health system serving Southeast Michigan as we rolled out a policy to limit admissions and transfers., Methods: in this retrospective study conducted at two stroke centers, we included consecutive patients presenting to the ED for whom a stroke alert was activated during the period extending from 3/20/20 to 5/20/20 and a similar period in 2019. We compared demographics, time metrics, and discharge outcomes between the two groups., Results: of 385 patients presented to the ED during the two time periods, 58% were African American. There was a significant decrease in the number of stroke patients presenting to the ED and admitted to the hospital between the two periods (p <0.001). In 2020, patients had higher presenting NIHSS (median: 2 vs 5, p = 0.012), discharge NIHSS (median: 2 vs 3, p = 0.004), and longer times from LKW to ED arrival (4.8 vs 9.4 h, p = 0.031) and stroke team activation (median: 10 vs 15 min, p = 0.006). In 2020, stroke mimics rates were lower among African Americans. There were fewer hospitalizations (p <0.001), and transfers from outside facilities (p = 0.015)., Conclusion: a trend toward faster stroke care in the ED was observed during the pandemic along with dramatically reduced numbers of ED visits, hospitalizations and stroke mimics. Delayed ED presentations and higher stroke severity characterized the African American population, highlighting deepening of racial disparities during the pandemic., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 Elsevier Inc.

Introduction: Stroke affects all ages. Despite increased incidence in those <65 years, little is known about age-based differences in inpatient rehabilitation management and outcomes., Objectives: To investigate management and outcomes, comparing younger (<65 years) and older (≥65 years) patients with stroke, who received inpatient rehabilitation., Methods: Multicentre, cross-sectional study using data from Australian hospitals who participated in the Stroke Foundation national stroke rehabilitation audit (2016-2018). Chi-square tests compared characteristics and care by age. Multivariable regression models were used to compare outcomes by age (e.g. length of stay). Models were adjusted for sex, stroke type and severity factors., Results: 7,165 audited cases from 127 hospitals; 23% <65 years (66% male; 72% ischaemic stroke). When compared to older patients, younger patients were more likely male (66% vs 52%); identify as Aboriginal or Torres Strait Islander (6% vs 1%); be less disabled on admission; receive psychology (46% vs 34%) input, and community reintegration support, including return to work (OR 1.47, 95% CI 1.03, 2.11), sexuality (OR 1.60, 95% CI 1.39, 1.84) and self-management (OR 1.39, 95% CI 1.23, 1.57) advice. Following adjustment, younger patients had longer lengths of stay (coeff 3.54, 95% CI 2.27, 4.81); were more likely to be independent on discharge (aOR 1.96, 95% CI 1.68, 2.28); be discharged to previous residences (aOR 1.64, 95% CI 1.41, 1.91) and receive community rehabilitation (aOR: 2.27, 95% CI 1.91, 2.70)., Conclusions: Age-related differences exist in characteristics, management and outcomes for inpatients with stroke accessing rehabilitation in Australia., (Copyright © 2021 Elsevier Inc.

Background: The use of thoracic endovascular aortic repair (TEVAR) has significantly improved the ability to treat traumatic aortic injuries (tTEVAR). We sought to determine whether a greater center volume correlated with better outcomes., Methods: Vascular Quality Initiative data of TEVAR (2011-2017) for trauma were used in the present analysis. Using the distribution of the annual case volume at the participating centers, the sample was stratified into three terciles. In-hospital mortality at high-volume centers (HVCs) and low-volume centers (LVCs) was compared after adjustment for risk factors established in our previous Vascular Quality Initiative-based risk model containing age, gender, renal impairment, left subclavian artery involvement, and select concomitant injuries., Results: A total of 619 tTEVAR cases were studied across 74 centers. HVCs (n = 184 cases) had performed ≥4.9 cases annually and LVCs (n = 220 cases) had performed ≤2.4 cases annually. Both crude mortality (4.4% vs 8.6%; P = .22) and adjusted odds of mortality (odds ratio, 0.44; 95% confidence interval, 0.18-1.09; P = .08) showed a trend toward better outcomes for tTEVAR performed at HVCs than at LVCs. The addition of center volume to our previous multivariate model significantly improved its discriminative ability (C-statistic, 0.90 vs 0.88; P = .02). The overall TEVAR volume (for all indications) was not associated with increased odds of mortality for tTEVAR (odds ratio, 0.46; 95% confidence interval, 0.17-1.20; P = .11), nor did it improve the model's discriminative ability., Conclusions: Higher volume centers showed improved perioperative mortality after tTEVAR. The thoracic aortic trauma volume was more predictive than the overall TEVAR volume, suggesting that technical expertise is not the driving factor. Stable patients might benefit from transfer to a higher volume center before repair., (Copyright © 2020 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.)

Background: Widespread adoption of endovascular aneurysm repair has led to a consequential decline in the use of open aneurysm repair (OAR). This evolution has had significant ramifications on vascular surgery training paradigms and contemporary practice patterns among established surgeons. Despite being the subject of previous analyses, the surgical volume-outcome relationship has remained a focus of controversy. At present, little is known about the complex interaction of case volume and surgeon experience with patient selection, procedural characteristics, and postoperative complications of OAR. The purpose of the present analysis was to examine the association between surgeon annual case volume and years of practice experience with OAR., Methods: All infrarenal OARs (n = 11,900; elective, 70%; nonelective, 30%) included in the Society for Vascular Surgery Vascular Quality Initiative from 2003 to 2019 were examined. Surgeon experience was defined as years in practice after training. The experience level at repair was categorized chronologically (≤5 years, n = 1667; 6-10 years, n = 1887; 11-15 years, n = 1806; ≥16 years, n = 6540). The annual case volume was determined by the number of OARs performed by the surgeon annually (median, five cases). Logistic regression was used to perform risk adjustment of the outcomes across surgeon experience and volume (five or fewer vs more than five cases annually) strata for in-hospital major complications and 30-day and 1-year mortality., Results: Practice experience had no association with unadjusted mortality (30-day death: elective, P = .2; nonelective, P = .3; 1-year death: elective, P = .2; nonelective, P = .2). However, more experienced surgeons had fewer complications after elective OAR (25% with ≥16 years vs 29% with ≤5 years; P = .004). A significant linear correlation was identified between increasing surgeon experience and performance of a greater proportion of elective OAR (P-trend < .0001). Risk adjustment (area under the curve, 0.776) revealed that low-volume (five or fewer cases annually) surgeons had inferior outcomes compared with high-volume surgeons across the experience strata for all presentations. In addition, high-volume, early career surgeons (≤5 years' experience) had outcomes similar to those of older, low-volume surgeons (P > .1 for all pairwise comparisons). Early career surgeons (≤5 years) had operated on a greater proportion of elective patients with American Society of Anesthesiologists class ≥4 (35% vs 30% [≥16 years' experience]; P = .0003) and larger abdominal aortic aneurysm diameters (mean, 62 vs 59 mm [≥16 years' experience]; P < .0001) compared with all other experience categories. Similarly, the use of a suprarenal cross-clamp occurred more frequently (26% vs 22% [≥16 years' experience]; P = .0009) but the total procedure time, estimated blood loss, and renal and/or visceral ischemia times were all greater for less experienced surgeons (P-trend < .0001)., Conclusions: Annual case volume appeared to be more significantly associated with OAR outcomes compared with the cumulative years of practice experience. To ensure optimal OAR outcomes, mentorship strategies for "on-boarding" early career, as well as established, low-volume, aortic aneurysm repair surgeons should be considered. These findings have potential implications for widespread initiatives surrounding regulatory oversight and credentialing paradigms., (Copyright © 2020 Society for Vascular Surgery.

Objective: We evaluated whether volume-based, rather than time-based, annual reporting of center outcomes for coronary artery bypass grafting may improve inference of quality, assuming that large center-level year-to-year outcome variability is related to statistical noise., Methods: We analyzed 2012 to 2016 data on isolated coronary artery bypass grafting using statewide outcome reports from New York and California. Annual changes in center-level observed-to-expected mortality ratio represented stability of year-to-year outcomes. Cubic spline fit related the annual observed-to-expected ratio change and center volume. Volume above the inflection point of the spline curve indicated centers with low year-to-year change in outcome. We compared observed-to-expected ratio changes between centers below and above the volume threshold and observed-to-expected ratio changes between consecutive annual and biennial measurements., Results: There were 155 centers with median annual volume of 89 (interquartile range, 55-160) for isolated coronary artery bypass grafting. The inflection point of observed-to-expected ratio variability was observed at 111 cases/year. Median year-to-year observed-to-expected ratio change for centers performing less than 111 cases (62 centers) was greater at 0.83 (0.26-1.59) compared with centers performing 111 cases or more (93 centers) at 0.49 (022-0.87) (P < .001). By aggregating the outcome over 2 years, centers above the 111-case threshold increased from 93 centers (60%) to 118 centers (76%), but the median observed-to-expected change for all centers was similar between annual aggregates at 0.70 (0.26-1.22) compared with observed-to-expected change between biennial aggregates at 0.54 (0.23-1.02) (P = .095)., Conclusions: Center-level, risk-adjusted coronary artery bypass grafting mortality varies significantly from one year to the next. Reporting outcomes by specific case volume may complement annual reports., (Published by Elsevier Inc.)

Objective: Databases are essential in evaluating surgical outcomes and gauging the implementation of new techniques. However, there are important differences in how data from administrative databases and surgical quality improvement (QI) registries are collected and interpreted. Therefore, we aimed to compare trends, demographics, and outcomes of open and endovascular abdominal aortic aneurysm (AAA) repair in an administrative database and two QI registries., Methods: We identified patients undergoing open and endovascular repair of intact and ruptured AAAs between 2012 and 2015 within the National Inpatient Sample (NIS), the National Surgical Quality Improvement Program (NSQIP), and the Vascular Quality Initiative (VQI). We described the differences and trends in overall AAA repairs for each data set. Moreover, patient demographics, comorbidities, mortality, and complications were compared between the data sets using Pearson χ 2 test., Results: A total of 140,240 NIS patients, 10,898 NSQIP patients, and 26,794 VQI patients were included. Ruptured repairs composed 8.7% of NIS, 11% of NSQIP, and 7.9% of VQI. Endovascular aneurysm repair (EVAR) rates for intact repair (range, 83%-84%) and ruptured repair (range, 51%-59%) were similar in the three databases. In general, rates of comorbidities were lower in NIS than in the QI registries. After intact EVAR, in-hospital mortality rates were similar in all three databases (NIS 0.8%, NSQIP 1.0%, and VQI 0.8%; P = .06). However, after intact open repair and ruptured repair, in-hospital mortality was highest in NIS and lowest in VQI (intact open: NIS 5.4%, NSQIP 4.7%, and VQI 3.5% [P < .001]; ruptured EVAR: NIS 24%, NSQIP 20%, and VQI 16% [P < .001]; ruptured open: NIS 36%, NSQIP 31%, and VQI 26% [P < .001]). After stratification by intact and ruptured presentation and repair strategy, several discrepancies in morbidity rates remained between the databases. Overall, the number of cases in NSQIP represents 7% to 8% of the repairs in NIS, and the number of cases in VQI grew from 12% in 2012 to represent 23% of the national sample in 2015., Conclusions: NIS had the largest number of patients as it represents the nationwide experience and is an essential tool to evaluate trends over time. The lower in-hospital mortality seen in NSQIP and VQI questions the generalizability of the studies that use these QI registries. However, with a growing number of hospitals engaging in granular QI initiatives, these QI registries provide a valuable resource to potentially improve the quality of care provided to all patients., (Copyright © 2020 Society for Vascular Surgery.

Objective: To examine which factors are driving improvement in the Dialysis Facility Compare (DFC) star ratings and to test whether nonclinical facility characteristics are associated with observed longitudinal changes in the star ratings., Data Sources: Data were collected from eligible patients in over 6,000 Medicare-certified dialysis facilities from three annual star rating and individual measure updates, publicly released on DFC in October 2015, October 2016, and April 2018., Study Design: Changes in the star rating and individual quality measures were investigated across three public data releases. Year-to-year changes in the star ratings were linked to facility characteristics, adjusting for baseline differences in quality measure performance., Data Collection: Data from publicly reported quality measures, including standardized mortality, hospitalization, and transfusion ratios, dialysis adequacy, type of vascular access for dialysis, and management of mineral and bone disease, were extracted from annual DFC data releases., Principal Findings: The proportion of four- and five-star facilities increased from 30.0% to 53.4% between October 2015 and April 2018. Quality improvement was driven by the domain of care containing the dialysis adequacy and hypercalcemia measures. Additionally, independently owned facilities and facilities belonging to smaller dialysis organizations had significantly lower odds of year-to-year improvement than facilities belonging to either of the two large dialysis organizations (Odds Ratio [OR]: 0.736, 95% Confidence Interval [CI]: 0.631-0.856 and OR: 0.797, 95% CI: 0.723-0.879, respectively)., Conclusions: The percentage of four- and five-star facilities has increased markedly over a three-year time period. These changes were driven by improvement in the specific quality measures that may be most directly under the control of the dialysis facility., (© 2020 Health Research and Educational Trust.)

Background: Posterior circulation stroke is characterized by poor prognosis because its optimal thrombolysis "time window" is always missed. After mechanical thrombectomy (MT), the recanalization rate of posterior circulation obstruction is significantly increased, but prognosis remains poor. To best manage patients, prognostic factors are needed to inform MT triaging after posterior circulation stroke., Methods: A systematic literature search was done for the period through April 2020. Studies included those with posterior circulation stroke cases that underwent MT. The primary outcome measure in this study was the modified Rankin Scale on day 90., Results: No outcome differences were found in gender, atrial fibrillation, smoking, and coronary artery disease (OR = 1.07, 95% CI: 0.90-1.28; OR = 1.02, 95% CI: 0.82-1.26; OR = 1.26, 95% CI: 0.94-1.68; and OR = 0.84, 95% CI: 0.58-1.22, respectively). Hypertension, diabetes mellitus, and previous stroke correlated with poorer prognosis (OR = 0.61, 95% CI: 0.48-0.77; OR = 0.60, 95% CI: 0.50-0.73; and OR = 0.74, 95% CI: 0.55-0.99, respectively). However, hyperlipidemia correlated with better prognosis (OR = 1.28, 95% CI: 1.04-1.58)., Conclusion: Our analysis indicates that hypertension, diabetes mellitus, or previous stroke correlate with poorer outcomes. Intriguingly, hyperlipidemia correlates with better prognosis. These factors may help inform triage decisions when considering MT for posterior circulation stroke patients. However, large, multicenter, randomized controlled trials are needed to validate these observations., (© 2020 S. Karger AG, Basel.)

Background: Provider profiling involves comparing the performance of hospitals on indicators of quality of care. Typically, provider profiling examines the performance of hospitals on each quality indicator in isolation. Consequently, one cannot formally examine whether hospitals that have poor performance on one indicator also have poor performance on a second indicator., Methods: We used Bayesian multivariate response random effects logistic regression model to simultaneously examine variation and covariation in multiple binary indicators across hospitals. We considered 7 binary patient-level indicators of quality of care for patients presenting to hospital with a diagnosis of acute stroke. We examined between-hospital variation in these 7 indicators across 86 hospitals in Ontario, Canada., Results: The number of patients eligible for each indicator ranged from 1321 to 14 079. There were 7 pairs of indicators for which there was a strong correlation between a hospital's performance on each of the 2 indicators. Twenty-nine of the 86 hospitals had a probability higher than 0.90 of having worse performance than average on at least 4 of the 7 indicators. Seven of the 86 of hospitals had a probability higher than 0.90 of having worse performance than average on at least 5 indicators. Fourteen of the 86 of hospitals had a probability higher than 0.50 of having worse performance than average on at least 6 indicators. No hospitals had a probability higher than 0.50 of having worse performance than average on all 7 indicators., Conclusions: These findings suggest that there are a small number of hospitals that perform poorly on at least half of the quality indicators, and that certain indicators tend to cluster together. The described methods allow for targeting quality improvement initiatives at these hospitals.

Background: Monitoring efforts to improve access to transplantation requires a definition of the population attributable to a transplant center. Previously, assessment of variation in transplant care has focused on differences between administrative units-such as states-rather than units derived from observed care patterns. We defined catchment areas (transplant referral regions [TRRs]) from transplant center care patterns for population-based assessment of transplant access., Methods: We used US adult transplant listings (2006-2016) and Dartmouth Atlas catchment areas to assess the optimal method of defining TRRs. We used US Renal Data System and Scientific Registry of Transplant Recipient data to compare waitlist- and population-based kidney transplant rates., Results: We identified 110 kidney, 67 liver, 85 pancreas, 68 heart, and 43 lung TRRs. Most patients were listed in their assigned TRR (kidney: 76%; liver: 75%; pancreas: 75%; heart: 74%; lung: 72%), although the proportion varied by organ (interquartile range for kidney, 65.7%-82.5%; liver, 58.2%-78.8%; pancreas, 58.4%-81.1%; heart, 63.1%-80.9%; lung, 61.6%-76.3%). Patterns of population- and waitlist-based kidney transplant rates differed, most notably in the Northeast and Midwest., Conclusions: Patterns of TRR-based kidney transplant rates differ from waitlist-based rates, indicating that current metrics may not reflect transplant access in the broader population. TRRs define populations served by transplant centers and could enable future studies of how transplant centers can improve access for patients in their communities.

Aims: To assess the impact of the lockdown due to coronavirus disease 2019 (COVID-19) on key quality indicators for the treatment of ST-segment elevation myocardial infarction (STEMI) patients., Methods: Data were obtained from 41 hospitals participating in the prospective Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) study, including 15,800 patients treated for acute STEMI from January 2017 to the end of March 2020., Results: There was a 12.6% decrease in the total number of STEMI patients treated at the peak of the pandemic in March 2020 as compared to the mean number treated in the March months of the preceding years. This was accompanied by a significant difference among the modes of admission to hospitals (p = 0.017) with a particular decline in intra-hospital infarctions and transfer patients from other hospitals, while the proportion of patients transported by emergency medical service (EMS) remained stable. In EMS-transported patients, predefined quality indicators, such as percentages of pre-hospital ECGs (both 97%, 95% CI = - 2.2-2.7, p = 0.846), direct transports from the scene to the catheterization laboratory bypassing the emergency department (68% vs. 66%, 95% CI = - 4.9-7.9, p = 0.641), and contact-to-balloon-times of less than or equal to 90 min (58.3% vs. 57.8%, 95%CI = - 6.2-7.2, p = 0.879) were not significantly altered during the COVID-19 crisis, as was in-hospital mortality (9.2% vs. 8.5%, 95% CI = - 3.2-4.5, p = 0.739)., Conclusions: Clinically important indicators for STEMI management were unaffected at the peak of COVID-19, suggesting that the pre-existing logistic structure in the regional STEMI networks preserved high-quality standards even when challenged by a threatening pandemic., Clinical Trial Registration: NCT00794001.

Background: The novel coronavirus disease 2019 (COVID-19) outbreak raised concerns over healthcare systems' ability to provide suitable care to stroke patients. In the present study, we examined the provision of stroke care in Kobe City during the COVID-19 epidemic, where some major stroke centers ceased to provide emergency care., Methods: This was a cross-sectional study. The Kobe Stroke Network surveyed the number of stroke patients admitted to all primary stroke centers (PSCs) in the city between March 1 and May 23, 2020, and between March 3 and May 25, 2019. In addition, online meetings between all PSC directors were held regularly to share information. The survey items included emergency response system characteristics, number of patients with stroke hospitalized within 7 days of onset, administered treatment types (IV rt-PA, mechanical thrombectomy, surgery, and endovascular therapy), and stroke patients with confirmed COVID-19., Results: During the period of interest in 2020, the number of stroke patients hospitalized across 13 PSCs was 813, which was 15.5% lower than that during the same period of 2019 (p = 0.285). The number of patients admitted with cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage decreased by 15.4% (p = 0.245), 16.1% (p = 0.659), and 14.0% (p = 0.715), respectively. However, the rates of mechanical thrombectomy and surgery for intracerebral hemorrhage were slightly increased by 12.1% (p = 0.754) and 5.0% (p = 0.538), respectively. PSCs that ceased to provide emergency care reported a decrease in the number of stroke cases of 65.7% compared with the same period in 2019, while other PSCs reported an increase of 0.8%. No case of a patient with stroke and confirmed COVID-19 was reported during the study period., Conclusion: Kobe City was able to maintain operation of its stroke care systems thanks to close cooperation among all city PSCs and a temporal decrease in the total number of stroke cases., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Elsevier Inc.

Severe combined immunodeficiency (SCID) is T cell development disorders in the immune system and can be detected at birth. As of December 2018, all 53 newborn screening (NBS) programs within the United States and associated territories offer universal screening for SCID. The Association of Public Health Laboratories (APHL), along with the Immune Deficiency Foundation (IDF), surveyed public health NBS system laboratory and follow-up coordinators regarding their NBS program's screening methodologies and targets, protocols for stakeholder notifications, and long-term follow-up practices. This report explores the variation that exists across NBS practices, revealing needs for efficiencies and educational resources across the NBS system to ensure the best outcomes for newborns., (Copyright © 2020 Sheller, Ojodu, Griffin, Edelman, Yusuf, Pigg, Huston, Fitzek, Boyle and Singh.)

Background: Guideline for Pharmacological Therapy for Schizophrenia was published by the Japanese Society of Neuropsychopharmacology in 2015. "Effectiveness of Guidelines for Dissemination and Education in psychiatric treatment (EGUIDE)" project aimed to standardize medical practice using quality indicators (QIs) as indices to evaluate the quality of medical practice. In this study, we have reported the quality indicator values of prescription before the beginning of the guideline lectures in the EGUIDE project to ascertain the baseline status of treating patients with schizophrenia., Methods: A cross-sectional, retrospective case record survey was conducted, involving 1164 patients with schizophrenia at the time of discharge. We checked all types and dosage of psychotropic drugs., Results: Forty-three percent of patients had antipsychotic polypharmacy, and substantial concomitant medication was observed (antidepressants; 8%, mood stabilizers: 37%, anxiolytics or hypnotics: 68%)., Conclusions: In the results obtained in this study, we plant to report changes in the effectiveness of education in the EGUIDE project near the future., (© 2020 The Authors.

Purpose: As part of the implementation of quality registration in Iceland we used retrospective data to compare diagnosis and treatment of invasive breast cancer between Iceland and Sweden., Materials and Methods: Information on all patients diagnosed with invasive breast cancer in Iceland 2016-2017 was obtained from the Icelandic Cancer Registry. Hospital records were used to register variables in an electronic form adapted from the Swedish quality registration, and compared with data from Sweden for the same period. A chi-square test was used to compare ratios., Results: A total of 486 cases of breast cancer were diagnosed in Iceland and 15.325 in Sweden. A lower proportion of 40-69 year old women were diagnosed within the screening programme in Iceland (46%) compared to Sweden (60%) (p<0.01). Multidisciplinary tumor board meetings held before and after surgery were less frequent in Iceland (92% vs. 96%) compared to Sweden (98% vs. 99%) in 2016 (p<0,01) but no difference was seen in 2017. A sentinel node surgery was done in 69% of the cases in Iceland compared to 94% in Sweden (p<0,01). For cancers ≤30mm breast conserving surgery was done in 48% cases in Iceland but 80% in Sweden (p<0,01). In Iceland 87% of the cases had radiation therapy after breast conserving surgery but 94% in Sweden (p<0,01). Among mastectomy patients with lymph node metastases, 49% received radiation therapy in Iceland compared to 83% in Sweden (p<0,01)., Conclusion: Differences were seen in several areas of diagnosis and treatment of invasive breast cancer between Iceland and Sweden. With quality registration it will be possible to monitor and set goals for the diagnosis and treatment, with the aim of providing the best treatment to as many patients as possible.

Background: Little is known about patients discharged to hospice following hospitalization for complications of cirrhosis., Aim: We sought to understand the current pattern of hospice utilization in patients with cirrhosis by evaluating the North American Consortium for the Study of End-stage Liver Disease (NACSELD) cohort., Methods: Patients with cirrhosis from 14 tertiary-care hepatology centers across North America non-electively hospitalized and prospectively enrolled were evaluated. Exclusion criteria included HIV infection, transplantation or non-hepatic malignancy. Random computer-based propensity score matching was undertaken in a 1:2 ratio based on admission MELD score ± 3 points., Results: Totally, 2718 patients were enrolled, 5% (N = 132) were discharged to hospice, 6% (N = 171) died, and the rest were discharged alive. Patients discharged to hospice were older (60 vs. 57 years, p = 0.04), less likely to have had SBP (13% vs. 28%, p = 0.002) and be listed for liver transplantation (11% vs. 26%, p = 0.0007). Features, on multivariable modeling, associated with increased probability of discharge to hospice as opposed to being discharged alive: grade-3-4 hepatic encephalopathy, a higher Child-Turcotte-Pugh (CTP) score, and a higher discharge serum creatinine; however, a higher serum sodium, being listed for transplant and being prescribed rifaximin or a statin were protective from hospice discharge., Conclusion: Patients with more advanced liver disease, hepatic encephalopathy, renal dysfunction, and those not candidates for liver transplantation were more likely to be discharged to hospice. However, in this sick multinational cohort of cirrhotic inpatients, it seems that hospice is markedly underutilized (5%) since 25% of patients not discharged to hospice died within 6 months.

Background There are limited data to inform policy mandating primary percutaneous coronary intervention (PPCI) volume benchmarks for catheterization laboratories in low- and middle-income countries. Methods and Results This prospective state-wide registry included ST-segment-elevation myocardial infarction patients with symptoms of <12 hours, or with ongoing ischemia at 12 to 24 hours, reperfused with PPCI. From June 2013 to March 2016, we recruited 5560 consecutive patients. We categorized hospitals on the basis of annual PPCI volumes into low, medium, and high volume (<100, 100-199, and ≥200 PPCIs per year, respectively). Kaplan-Meier curves and Cox regression models were used to examine the association between PPCI volume and 1-year mortality. Among 42 recruiting hospitals, there were 24 (57.2%) low-volume, 8 (19%) medium-volume, and 10 (23.8%) high-volume hospitals. The median (25th-75th percentile) TIMI (Thrombolysis in Myocardial Infarction) ST-segment-elevation myocardial infarction risk score was 3 (2-5). Cardiac arrest before admission occurred in 4.2%, 2.1%, and 2.9% of cases at low-, medium-, and high-volume hospitals, respectively ( P =0.02). Total ischemic time differed significantly among low-volume (median [25th-75th percentile], 3.5 [2.4-5.5] hours), medium-volume (median, 3.8 [25th-75th percentile, 2.58-6.05] hours), and high-volume hospitals (median, 4.16 [25th-75th percentile 2.8-6.3] hours) ( P =0.01). Vascular access was radial in 61.5%, 71.3%, and 63.2% of cases at low-, medium-, and high-volume hospitals, respectively ( P =0.01). The observed 1-year mortality rate was 6.5%, 3.4%, and 8.6% at low-, medium- and high-volume hospitals, respectively ( P <0.01), and the difference did not attenuate after multivariate adjustment (low versus medium: hazard ratio [95% CI], 1.80 [1.12-2.90]; high versus medium: hazard ratio [95% CI], 2.53 [1.78-3.58]) ( P <0.01). Conclusions Low- and middle-income countries, like India, may have a nonlinear relationship between institutional PPCI volume and outcomes, partly driven by procedural variations and inequalities in access to care.

Background: Measles is a vaccine preventable, highly transmissible viral infection that affects mostly children under five years. It has been ear marked for elimination and Nigeria adopted the measles elimination strategies of the World Health Organization (WHO) African region to reduce cases and deaths. This study was done to determine trends in measles cases in Bayelsa state, to describe cases in terms of person and place, identify gaps in the case-based surveillance data collection system and identify risk factors for measles infection., Methods: We carried out a secondary data analysis of measles case-based surveillance data for the period of January 2014 to December 2018 obtained in Microsoft Excel from the State Ministry of Health. Cases were defined according to WHO standard case definitions. We calculated frequencies, proportions, estimated odds ratios (OR), 95% confidence intervals (CI) and multivariate analysis., Results: A total of 449 cases of measles were reported. There were 245(54.6%) males and the most affected age group was 1-4 years with 288(64.1%) cases. Of all cases, 289(9.35%) were confirmed and 70 (48.27%) had received at least one dose of measles vaccine. There was an all-year transmission with increased cases in the 4th quarter of the year. Yenegoa local government area had the highest number of cases. Timeliness of specimen reaching the laboratory and the proportion of specimens received at the laboratory with results sent to the national level timely were below WHO recommended 80% respectively. Predictors of measles infection were, age less than 5 years (AOR: 0.57, 95% CI: 0.36-0.91) and residing in an urban area (AOR: 1.55, 95% CI:1.02-2.34)., Conclusions: Measles infection occurred all-year round, with children less than 5 years being more affected. Measles case-based surveillance system showed high levels of case investigation with poor data quality and poor but improving indicators. Being less than 5 years was protective of measles while living in urban areas increased risk for infection. We recommended to the state government to prioritize immunization activities in the urban centers, start campaigns by the 4th quarter and continue to support measles surveillance activities and the federal government to strengthen regional laboratory capacities.

Objectives: The aim of this study was to describe the performance and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in Michigan., Background: CTO PCI has been associated with reduction in angina, but previous registry analyses showed a higher rate of major adverse cardiac events with this procedure., Methods: To study uptake and outcomes of CTO PCI in Michigan, patients enrolled in the BMC2 (Blue Cross Blue Shield of Michigan Cardiovascular Consortium) registry (2010 to 2017) were evaluated. CTO PCI was defined as intervention in a 100% occluded coronary artery ≥3 months old., Results: Among 210,172 patients enrolled in the registry, 7,389 CTO PCIs (3.5%) were attempted, with 4,614 (58.3%) achieving post-procedural TIMI (Thrombolysis In Myocardial Infarction) flow grade 3. The proportion of PCIs performed on CTOs increased over the study period (from 2.67% in 2010 to 4.48% in 2017). Thirty of 47 hospitals performed >50 CTO interventions in 2017. Pre-procedural angina class ≤2 was present in one-quarter, and functional assessment for ischemia was performed in 46.6% of patients. Major complications occurred in 245 patients (3.3%) and included death (1.4%), post-procedural stroke (0.4%), cardiac tamponade (0.5%), and urgent coronary artery bypass graft surgery (1.3%). Procedural success improved modestly from 44.5% in 2010 to 54.9% in 2017 (p for trend < 0.001). Rates of in-hospital mortality (p for trend = 0.247) and major adverse cardiac event (p for trend = 0.859) for CTO PCI remained unchanged over the study period., Conclusions: The rate of CTO PCI in Michigan increased over the study period. Although the success rate of CTO PCI has increased modestly in contemporary practice, it remained far below the >80% reported by select high-volume CTO operators. The rate of periprocedural major adverse cardiac events or death remained unchanged over time. These data suggest room for improvement in the selection and functional assessment of CTO lesions before subjecting patients to the increased procedural risk associated with CTO PCI., (Copyright © 2020 American College of Cardiology Foundation.

Background There is a limited evidence base to support the volume-outcome relationship in patients undergoing percutaneous coronary intervention (PCI) for unprotected left main coronary artery disease (UPLMD). This study aimed to evaluate the relationship between institutional and operator volume and in-hospital outcomes in patients undergoing PCI for unprotected left main coronary artery disease. Methods and Results We analyzed characteristics and clinical outcomes of 24 320 patients undergoing PCI for unprotected left main coronary artery disease at 1102 hospitals by 7244 operators using data from the Japanese nationwide J-PCI Registry (National PCI Data Registry) between January 2014 and December 2017. We classified institutions and operators into quartiles based on the mean annual volume of PCI. A generalized linear mixed-effects model was used to evaluate the association between institutional and operator PCI volume and in-hospital outcomes. Among the 24 320 patients, 4027 (16.6%), 6147 (25.3%), and 14 146 (58.2%) presented with ST-segment-elevation myocardial infarction, non-ST-segment-elevation acute coronary syndrome, and stable ischemic heart disease; their crude in-hospital mortality was 15%, 3.1%, and 0.3%, respectively. Compared with patients in the lowest quartile of institutional volume (1-216 PCIs/y), the adjusted odds ratio of in-hospital death in patients in the second (217-323 PCIs/y), third (324-487 PCIs/y), and fourth (488-3015 PCIs/y) quartile of institutional volume was 0.75 (95% CI, 0.51-1.10; P =0.14), 0.87 (95% CI, 0.57-1.34; P =0.54), and 0.51 (95% CI, 0.30-0.86; P =0.01), respectively. These findings were consistent in rates of in-hospital death or any complication. Conversely, operator PCI volume was not significantly associated with in-hospital outcomes. Conclusions Institutional rather than operator-based PCI volume was associated with better in-hospital outcomes in patients undergoing PCI for unprotected left main coronary artery disease.

We sought to develop a quality standard for the delivery of psychotherapy for posttraumatic stress disorder (PTSD) that is both consistent with the underlying evidence supporting psychotherapy as a treatment for PTSD and associated with the best levels of symptom improvement. We quantified psychotherapy receipt during the initial year of PTSD treatment in a 10-year national cohort of Department of Veterans Affairs (VA) users who completed patient-reported outcome measurement as part of routine practice. We added progressively stringent measurement requirements. The most stringent requirement was associated with superior outcomes. Quality of psychotherapy for PTSD in the VA improved over time.

Background: There has been rapid growth in the demand for transcatheter aortic valve replacement (TAVR), which has the potential to overwhelm current capacity. This imbalance between demand and capacity may lead to prolonged wait times, and subsequent adverse outcomes while patients are on the waitlist. We sought to understand the relationship between regional differences in capacity, TAVR wait times and morbidity/mortality on the waitlist., Methods and Results: We modelled the effect of TAVR capacity, defined as the number of TAVR procedures per million residents/region, on the hazard of having a TAVR in Ontario from April 2012 to March 2017. Our primary outcome was the time from referral to a TAVR procedure or other off-list reasons on the waitlist/end of the observation period as measured in days. Clinical outcomes of interest were all-cause mortality, all-cause hospitalisations or heart failure-related hospitalisations while on the waitlist for TAVR. There was an almost fourfold difference in TAVR capacity across the 14 regions in Ontario, ranging from 31.5 to 119.5 TAVR procedures per million residents. The relationship between TAVR capacity and wait times was complex and non-linear. In general, increased capacity was associated with shorter wait times (p<0.001), reduced mortality (HR 0.94; p=0.08) and all-cause hospitalisations (p=0.009)., Conclusions: The results of the present study have important policy implications, suggesting that there is a need to improve TAVR capacity, as well as develop wait-time strategies to triage patients, in order to decrease wait times and mitigate the hazard of adverse patient outcomes while on the waitlist., Competing Interests: Competing interests: NF is a consultant for Edwards Life Sciences., (© Author(s) (or their employer(s)) 2020.

Background: Reducing hospital readmission after acute myocardial infarction (AMI) has the potential to both improve quality and reduce costs. As such, readmission after AMI has been a target of financial penalties through Medicare. However, substantial concern exists about potential adverse effects and efficacious readmission-reduction strategies are not well validated., Methods and Results: We started an AMI readmissions reduction program in November 2017. Between July 2016 and February 2019, hospital billing data were queried to detect all inpatient hospitalizations at the Massachusetts General Hospital for AMI. Thirty-day readmission was identified through hospital billing data, and mortality was extracted from our electronic health record. The data set was merged with claims data for patients in accountable care organizations to detect readmission at other hospitals. We performed segmented linear regression, adjusting for secular trend and case mix, to assess the independent association of our program on both outcome variables. After inclusion and exclusion criteria were applied, the study population included 2020 patients. The overall 30-day readmission rate was higher before the intervention than after the intervention (15.5% versus 10.7%, P =0.002). The overall 30-day mortality rate was similar in both time periods (1.8% versus 1.4%, P =0.457). The program was associated with initial reduction in 30-day readmission (-9.8%, P =0.0002) and 30-day mortality (-2.6%, P =0.041). The program did not change trend in 30-day readmission (+0.19% readmissions/mo, P =0.554) and trend in 30-day mortality (-0.21% deaths/mo, P =0.119)., Conclusions: An AMI readmissions reduction program that increases outpatient and emergency department (ED) access to cardiology care is associated with reduced 30-day readmission and 30-day mortality. Similar statistical techniques can be used to conduct a rigorous, mechanistic program evaluation of other quality improvement initiatives.

Background Rheumatic heart disease disproportionately affects women of reproductive age, as it increases the risk of cardiovascular complications and death during pregnancy and childbirth. In sub-Saharan Africa, clinical outcomes and adherence to guideline-based therapies are not well characterized for this population. Methods and Results In a retrospective cohort study of the Uganda rheumatic heart disease registry between June 2009 and May 2018, we used multivariable regression and Cox proportional hazards models to compare comorbidities, mortality, anticoagulation use, and treatment cascade metrics among women versus men aged 15 to 44 with clinical rheumatic heart disease. We included 575 women and 252 men with a median age of 27 years. Twenty percent had New York Heart Association Class III-IV heart failure. Among patients who had an indication for anticoagulation, women were less likely than men to receive a prescription of warfarin (66% versus 81%; adjusted odds ratio, 0.37; 95% CI, 0.14-0.96). Retention in care (defined as a clinic visit within the preceding year) was poor among both sexes in this age group (27% for men, 24% for women), but penicillin adherence rates were high among those retained (89% for men, 92% for women). Mortality was higher in men than women (26% versus 19% over a median follow-up of 2.7 years; adjusted hazard ratio, 1.66; 95% CI, 1.18-2.33). Conclusions Compared with men, women of reproductive age with rheumatic heart disease in Uganda have lower rates of appropriate anticoagulant prescription but also lower mortality rates. Retention in care is poor among both men and women in this age range, representing a key target for improvement.

Objectives: The aim of this study was to evaluate institutional variability in high radiation doses during percutaneous coronary intervention (PCI)., Background: It is unknown whether radiation safety practices are optimally applied across institutions performing PCI., Methods: Using data from a large statewide registry, PCI discharges between July 1, 2016, and March 31, 2018, with a procedural air kerma (AK) recorded were analyzed. PCI procedures were grouped by the performing hospital, and institutional frequency of procedural AK ≥5 Gy was calculated. Fitted hierarchical Bayesian modeling was performed to identify variables independently associated with an AK ≥5 Gy. The performing hospital was included as a random effect in the hierarchical model., Results: Among 36,201 PCI procedures at 28 hospitals, procedural AK was ≥5 Gy in 1,477 cases (4.1%), ≥10 Gy in 185 (0.5%), and ≥15 Gy in 105 (0.3%). The institutional frequency of procedural AK ≥5 Gy ranged from 0.0% to 10.9%. Bayesian modeling identified body mass index, dyslipidemia, diabetes, prior coronary bypass surgery, use of mechanical circulatory support, and the performing hospital as independent predictors of an AK ≥5 Gy. The median odds ratio for the performing hospital, representing an estimate of the contribution of interhospital variability in determining the odds of having a procedural AK ≥5 Gy, was 3.08 (95% confidence interval: 3.01 to 3.16)., Conclusions: Wide variability exists in the institutional frequency of procedural AK ≥5 Gy during PCI. After accounting for patient characteristics and procedural variables, the performing hospital appears to be a major factor in determining patient radiation dose in contemporary PCI., (Copyright © 2020 American College of Cardiology Foundation.

Background and Aim: Atrial Fibrillation is the leading cause of embolic stroke, yet less than half of high-risk patients with atrial fibrillation are on adequate stroke prevention with oral anticoagulants. Guidelines for the primary prevention of stroke recognize the emergency department as a location for physicians to identify atrial fibrillation and initiate anticoagulants. We sought to compare anticoagulant prescription rates in patients with atrial fibrillation in various provider settings to identify opportunities for improvement in cardioembolic stroke prevention., Methods: A retrospective cohort study of 436 patients with atrial fibrillation presenting to the emergency department from 2014 to 2018 was performed. Baseline characteristics, stroke risk, and rates of anticoagulant prescription were compared across 3 groups: (1) patients discharged from the emergency department, (2) patients admitted under observation status, and (3) patients admitted to inpatient hospital service., Results: Among 436 patients (47% women, 51% Hispanic), we identified 105 in the emergency department cohort, 131 in the observation cohort and 200 in the inpatient cohort. The average CHA 2 DS 2 -VASc score was 2.5 in the emergency department cohort, 2.6 in the observation cohort and 3.3 in the inpatient cohort. Anticoagulants were prescribed for high-risk patients (CHA 2 DS 2 -VASc score ≥ 2) in 17.5% (7/40) of the emergency department cohort compared to 73% (38/52, P< .0001) of the observation cohort and 80% (82/103 P< .0001) of the inpatient cohort., Conclusion: Patients with atrial fibrillation are more likely to be prescribed anticoagulants if admitted to inpatient or under observation status compared to the emergency department., (Copyright © 2019 Elsevier Inc.

Objective: Cardiovascular disease is the leading cause of death worldwide, responsible for 17.5 million deaths every year, of which 80% occur in low- and middle-income countries. Some 75% of the world does not have access to cardiac surgery when needed because of lack of infrastructure, human resources, and financial coverage. This study aims to map access to cardiac surgery around the world., Methods: A scoping review was done on access to cardiac surgery for an undifferentiated population. Workforce data were collected from the Cardiothoracic Surgery Network database and used to calculate numbers and ratios of adult and pediatric cardiac surgeons to population., Results: A total of 12,180 adult cardiac surgeons and 3858 pediatric cardiac surgeons were listed in the Cardiothoracic Surgery Network in August 2017, equaling 1.64 (0-181.82) adult cardiac surgeons and 0.52 (0-25.97) pediatric cardiac surgeons per million population globally. Large disparities existed between regions, ranging from 0.12 adult cardiac surgeons and 0.08 pediatric cardiac surgeons per million population (sub-Saharan Africa) to 11.12 adult cardiac surgeons and 2.08 pediatric cardiac surgeons (North America). Low-income countries possessed 0.04 adult cardiac surgeons and 0.03 pediatric cardiac surgeons per million population, compared with 7.15 adult cardiac surgeons and 1.67 pediatric cardiac surgeons in high-income countries., Conclusions: This study maps the current global state of access to cardiac surgery. Disparities exist between and within world regions, with a positive correlation between a nation's economic status and access to cardiac surgery. Low early mortality rates in low-resource settings suggest the possibility of high-quality cardiac surgery in low- and middle-income countries. There is the need to increase human and physical resources, while focusing on safety, quality, and efficiency to improve access to cardiac surgery for the 4.5 billion people without., (Copyright © 2019 The American Association for Thoracic Surgery.
