Validation of an electronic trigger to measure missed diagnosis of stroke in emergency departments.
Diagnostic errors are major contributors to preventable patient harm. In this study, the investigators validated the use of an electronic health record (EHR)-based trigger (e-trigger) to measure missed opportunities in stroke diagnosis in emergency departments (EDs). The investigators concluded that a symptom-disease pair-based e-trigger identified missed diagnoses of stroke with a modest positive predictive value, underscoring the need for chart review validation procedures to identify diagnostic errors in large data sets.

Modeling the impact of delaying transcatheter aortic valve replacement for the treatment of aortic stenosis in the era of COVID-19.
The objective of this study was to model the short term and 2-year overall survival for intermediate-risk and low-risk patients with severe symptomatic aortic stenosis (AS) undergoing timely or delayed transcatheter aortic valve replacement during the 2019 novel coronavirus (COVID-19) pandemic. Findings showed that prompt transcatheter aortic valve replacement for both intermediate-risk and low-risk patients with severe symptomatic AS resulted in improved 2-year survival when local healthcare system resources were not significantly constrained by COVID-19.

Home blood pressure data visualization for the management of hypertension: using human factors and design principles.
Home blood pressure measurements have equal or even greater predictive value than clinic blood pressure measurements regarding cardiovascular outcomes. With advances in home blood pressure monitors, there is an imminent flood of home measurements, but current electronic health record systems lack the functionality to allow us to use this data to its fullest. In this study, the investigators designed a data visualization display for blood pressure measurements to be used for shared decision making around hypertension.

Hospital to home transition for patients with stroke under bundled payments.
In this paper, the authors describe COMprehensive Post-Acute Stroke Services (COMPASS), a comprehensive transitional care intervention focused on discharge from the acute care setting to home. The COMPASS care model is aligned with the incentive structures and essential components of bundled payments in terms of care coordination, patient assessment, patient and family involvement, and continuity of care. They concluded that ongoing evaluation will inform the design of incorporating COMPASS-like transitional care interventions into a stroke bundle.

Poor weight recovery between stage 1 palliation and hospital discharge for infants with single ventricle physiology: an analysis of the NPC-QIC Phase II dataset.
The purpose of this study was to investigate change in weight-for-age z-scores (WAZ) and risk factors for impaired weight gain between stage 1 palliation (S1P) for single ventricle physiology and discharge. Data from the National Pediatric Cardiology Quality Improvement Collaborative Phase II database was analysed. Findings showed that nearly all infants lost weight after S1P, with little recovery by hospital discharge. At discharge, three-quarters of the infants were at-risk for impaired weight gain or had failure to thrive. Most risk factors associated with change in WAZ were unmodifiable or surrogates of disease severity.

Emergency department telemedicine consults decrease time to interpret computed tomography of the head in a multi-network cohort.
Telemedicine can improve access to emergency stroke care in rural areas, but the benefit of telemedicine across different types and models of telemedicine networks is unknown. The objectives of this study were to (1) identify the impact of telemedicine on ED stroke care, (2) identify if telemedicine impact varied by network, and (3) describe the variation in process outcomes by telemedicine across EDs.

Using a customer relationship management system to manage a quality improvement intervention.
HealthyHearts New York City (HHNYC), one of 7 cooperatives funded through the Agency for Healthcare Research and Quality's EvidenceNOW initiative, evaluated the impact of practice facilitation on implementation of the Million Hearts guidelines for cardiovascular disease prevention and treatment. Tracking the intervention required a system to facilitate process data collection that was also user-friendly and flexible. Coupled with protocols and training, a strategically planned and customizable customer relationship management system (CRMS) was implemented to support the quality improvement intervention with 257 small independent practices.

Strategy for reliable identification of ischaemic stroke, thrombolytics and thrombectomy in large administrative databases.
Administrative data are frequently used in stroke research. Ensuring accurate identification of patients who had an ischaemic stroke, and those receiving thrombolysis and endovascular thrombectomy (EVT) is critical to ensure representativeness and generalisability. In this study, the investigators examined differences in patient samples based on mode of identification, and proposed a strategy for future patient and procedure identification in large administrative databases.

Modeling the elective vascular surgery recovery after coronavirus disease 2019: implications for moving forward.
This study looked at the impact of delays in elective vascular surgery caused by the coronavirus pandemic. Data from a 35-hospital regional vascular surgical collaborative consisting of all hospitals performing vascular surgery in the state of Michigan was used to estimate the number of delayed surgical cases for adults undergoing carotid endarterectomy, carotid stenting, endovascular and open abdominal aortic aneurysm repair, and lower extremity bypass. Median statewide monthly vascular surgical volume before the pandemic was 439 procedures, with a maximum statewide monthly case volume of 519 procedures. For the month of April 2020, elective vascular surgery procedure volume decreased by ~90%. Modelling estimated it would take approximately 8 months to catch up with the backlog. The authors suggest that if hospitals across the collaborative shared the burden of backlogged cases, the recovery should be shortened to ~3 months.

Coronary revascularization outcomes in relation to skilled nursing facility use following hospital discharge.
Observational analyses comparing coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) among elderly or frail patients are likely biased by treatment selection. PCI is typically chosen for frail patients, while CABG is more common for patients with good recovery potential. In this study. The investigators hypothesized that skilled nursing facility (SNF) use after revascularization was a measure of relative frailty associated with outcomes following coronary revascularization.

Provider care team segregation and operative mortality following coronary artery bypass grafting.
The purpose of this study was to examine whether provider care team segregation within hospitals contributes to the higher mortality rate of Black patients following coronary artery bypass grafting compared to their White counterparts. Using national Medicare data, findings showed that Black patients who undergo coronary artery bypass grafting at a hospital with a higher level of provider care team segregation die more frequently after surgery than Black patients treated at a hospital with a lower level.

Improving smoking and blood pressure outcomes: the interplay between operational changes and local context.
This study identified conditions and operational changes linked to improvements in smoking and blood pressure (BP) outcomes in primary care using samples and interviews from a subset of 104 practices participating in EvidenceNOW, a multisite cardiovascular disease prevention initiative. The authors calculated Clinical Quality Measure improvements, with targets of 10-point or greater absolute improvements in the proportion of patients with smoking screening, and if relevant, counseling and the proportion of hypertensive patients with adequately controlled BP. Primary care staff were surveyed and interviewed. In clinician-owned practices, implementing a workflow to routinely screen and counsel patients on smoking cessation resources, or implementing a documentation change or a referral to a resource alone led to an improvement of at least 10 points in the smoking outcome. These improvements did not occur though in health- or hospital system-owned practices or in Federally Qualified Health Centers. BP outcome improved by at least 10 points among solo practices after medical assistants learned how to take an accurate BP. Among larger, clinician-owned practices, BP outcomes improvement took place when staff took a second BP measurement after the first measurement was elevated and when staff learned where to document this information in the electronic health record. For larger and health- and hospital system-owned practices, 50 or more hours of facilitation was needed to improve BP outcomes.

Patterns in continuous pulse oximetry data prior to pulseless electrical activity arrest in the general care setting.
This study’s objective was to understand if features derived from continuous pulse oximetry data can provide advanced warning of pulseless electrical activity arrest in general care inpatients. A retrospective analysis of SpO2 and pulse rate data derived from continuous pulse oximetry was performed for patients with electrical pulseless activity (n = 38) and control patients (n = 42). The pulseless electrical activity arrest group tended to have lower mean SpO2 and higher mean pulse rates over time intervals ranging from 1 minute to 1 hour. Several hours to the rescue event changes in variability were observed. Up to 20 minutes before rescue events, pulse rate features were significantly different from feature values for the preceding 30-minute interval. Similar results were found at 10 minutes before the event. These differences might be useful for predicting and preventing rescue events.

A machine learning model for identifying patients at risk for wild-type transthyretin amyloid cardiomyopathy.
Transthyretin amyloid cardiomyopathy, an often-unrecognized cause of heart failure, is now treatable with a transthyretin stabilizer. It is therefore important to identify at-risk patients who can undergo targeted testing for earlier diagnosis and treatment, prior to the development of irreversible heart failure. In this study, the investigators showed that a random forest machine learning model could identify potential wild-type transthyretin amyloid cardiomyopathy using medical claims data.

Adverse outcomes associated with inappropriate direct oral anticoagulant starter pack prescription among patients with atrial fibrillation: a retrospective claims-based study.
This retrospective analysis investigated the risk for bleeding events with higher dosing of direct oral anticoagulant (DOAC) in the first 1-3 weeks of treatment for patients with atrial fibrillation (AF). Findings showed that patients who received an inappropriate DOAC prescription were more likely to identify as Black. Rates of ED visits, hospitalizations, and deaths overall were numerically lower in patients with starter pack DOAC prescriptions. In contrast, rates of ED visits and hospitalizations related to significant bleeding were numerically higher in patients with starter pack DOAC prescriptions. Among patients with AF but without acute venous thromboembolism, those who received an inappropriate DOAC starter pack had numerically higher rates of severe bleeding leading to ED visits and hospitalizations compared to those prescribed an appropriate non-starter pack DOAC anticoagulant.

Preparing for bundled payments: impact of complications post-coronary artery bypass grafting on costs.
This study examined the impact of complications on bundled payments for coronary artery bypass grafting (CABG) for care provided from admission through 90 days post-discharge. The authors linked clinical and internal cost data for patients undergoing CABG from 2014 to 2017 at a single institution. They performed multivariable linear regression to evaluate drivers of high costs, adjusting for preoperative and intraoperative characteristics and postoperative complications. They reviewed records of 1789 patients undergoing CABG with an average of 2.7 vessels. A large proportion of patients were diabetic and obese. Factors associated with increased adjusted costs were preoperative renal failure, diabetes and body mass index, postoperative stroke, prolonged ventilation, rebleeding requiring reoperation, and renal failure with varying magnitude.

Regional changes in patterns of stroke presentation during the COVID-19 pandemic.
The authors sought to determine the effect of the coronavirus pandemic on patterns of stroke patient presentation and quality of care. They analyzed data from 25 New England hospitals: one urban, academic, comprehensive stroke center and telestroke hub, and 24 spoke hospitals in the same telestroke network. They included all telestroke consultations from the 24 spokes, and stroke admissions to the comprehensive stroke center hub from November 2019 through April 2020. They compared rates of presentation, timeliness presentation, and quality of care pre- versus post-March 2020. They also examined trends in patient demographics, stroke severity, timeliness, diagnosis including large vessel occlusion, alteplase use, and endovascular thrombectomy among eligible subjects. Among 1248 patient presentations, telestroke consultations and ischemic stroke patient admissions decreased through the hub and spoke network. Age and stroke severity were unchanged during the study period. However, rates of adherence for the quality measures dysphagia screening, early antithrombotic initiation, and early venous thromboembolism prophylaxis were reduced during the pandemic.

Association of blood pressure variability and diuretics with cardiovascular events in patients with chronic kidney disease stages 1-5.
This study looked at whether blood pressure variability (BPV) is associated with cardiovascular outcomes and end-stage kidney disease (ESKD) in patients with chronic kidney disease. The authors studied US veterans with nondialysis chronic kidney disease stages 1-5 and hypertension on nondiuretic antihypertensive monotherapy. This case-control study compared veterans on only one antihypertensive prescription with those who were prescribed a second antihypertensive prescription. Each group had 31,394 participants. BPV was associated with composite cardiovascular events. It was associated with cardiovascular events and death but not ESKD in patients with chronic kidney disease.

Effect of initiating cardiac rehabilitation after myocardial infarction on subsequent hospitalization in older adults.
Outpatient cardiac rehabilitation (CR) participation after myocardial infarction (MI) reduces all-cause mortality; however, less is known about effects of CR on post-MI hospitalization. The objective of this study was to investigate effects of CR on hospitalization following acute MI among older adults. The investigators concluded that this study provided evidence that CR could reduce the 1-yr risk of cardiovascular and all-cause hospital admissions in Medicare aged MI survivors.

Effect of concomitant deep venous reflux on truncal endovenous ablation outcomes in the Vascular Quality Initiative.
This study looked at outcomes for patients with varicose veins (C2 disease) undergoing truncal endovenous ablation with and without deep venous reflux. Data from the Vascular Quality Initiative was analyzed from 2015 to 2019. A total of 4881 patients were included, with 46.2% having combined deep and superficial reflux. Follow-up around a year later (median 336.5 days) was conducted after. Patients with deep reflux were less likely to be female, more likely to be Caucasian, and had no difference in BMI. Additionally, there were no differences in rates of prior varicose vein treatments, number of pregnancies, or history of deep venous thrombosis. However, patients without deep reflux were more likely to use anticoagulants at the time of the procedure. Patients without deep reflux had slightly higher median preprocedural Venous Clinician Severity Score (VCSS) scores as well as postprocedural VCSS scores. Total symptom score was higher for patients without deep reflux before and after the procedure, but there was no change in symptom score after the procedure. Patients with deep reflux had substantially higher rates of complications with a particular increase in proximal thrombus extension.

Outcomes after truncal ablation with or without concomitant phlebectomy for isolated symptomatic varicose veins (C2 disease).
This study looked outcomes of patients with varicose veins (C2 disease) who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry. Data between January 2015 and March 2015 was used to investigate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy. Out of 3375 patients, 40.1% underwent isolated truncal ablation and the rest had the combined procedure of ablation and phlebectomy. Complications were low for both procedures (8.4% and 8.7%). Overall, improvement in symptoms was experienced by 94.4% of patients with more increases in patients undergoing ablation and phlebectomy than ablation alone. Both procedures are recommended by the authors to be covered by insurance.

Post-acute care use patterns among hospital service areas by older adults in the United States: a cross-sectional study.
This study examined post-stroke acute care patterns across Hospital Service Areas among a national stroke cohort of Medicare beneficiaries to determine drivers of variation in post-acute care service utilization. Data was extracted from 2013 to 2014 (174,498 total records across 3232 Hospital Service Areas). Patients’ residence ZIP codes were linked to the facility ZIP code where care was received. Patients were considered a “traveler” if they did not live in the Hospital Service Area where they received care. Only 23.5% of all patients received care in skilled nursing-only Hospital Service Areas although 73.4% of all Hospital Service Areas were skilled nursing-only. Thirty-five percent of all patients traveled to a different Hospital Service Area from their residence. Patients living in skilled nursing-only Hospital Service Areas had more than 5 times the odds of traveling compared to those living in Hospital Service Areas with skilled nursing, inpatient rehabilitation, and long-term care hospital services.
