TL;DR: The impact of the COVID-19 outbreak on STEMI care in Hong Kong is described through a handful of recent cases of patients with STEMI who underwent PPCI at a single center.
Abstract: Acute ST-segment–elevation myocardial infarction (STEMI) is a disease of high mortality and morbidity, and primary percutaneous coronary intervention (PPCI) is the typical recommended therapy.1,2 Systems of care have been established to expedite PPCI workflow to minimize ischemic time from symptom onset to definitive treatment in the catheterization laboratory. Little is known about the impact of public health emergencies like a community outbreak of infectious disease on STEMI systems of care. Since December 2019, the emergence of Coronavirus disease 2019 (COVID-19) in Wuhan, China, has evolved into a regional epidemic, including in Hong Kong, a city in Southern China. We describe the impact of the COVID-19 outbreak on STEMI care in Hong Kong through a handful of recent cases of patients with STEMI who underwent PPCI at a single center. We included patients with STEMI admitted via the Accident and Emergency Department and in whom PPCI was performed. We focus on the time period since January 25, 2020, when hospitals in the city started to institute emergency infection protocols to contain COVID-19. This required hospitals to suspend all nonessential visits and adjust clinical in-patient and out-patient services. Indications for PPCI were according to the international guidelines.1,2 Study exclusion criteria included inpatient STEMI (n=1), STEMI with unknown symptom onset time (n=3), and cardiac arrest patients (n=2). Our hospital has offered 24/7 PPCI service to all eligible patients presenting with acute STEMI since 2010 per standard Accident and Emergency Department protocol. When STEMI is diagnosed, a PPCI team is activated after cardiology evaluation. Data on key time points in STEMI care are recorded in a clinical registry. Symptom-onset-to-first-medicalcontact time is defined as the time from patient-reported chest discomfort onset time to the time of first medical contact. Door-to-device time is defined as the time from Accident and Emergency Department arrival to successful wire crossing time during PPCI. Catheterization laboratory arrival-to-device time is defined as the time from patient arrival in the catheterization laboratory to successful wire crossing time. From January 25, 2020, to February 10, 2020, we observed changes in time components of STEMI care among the aggregate group of 7 consecutive patients who underwent PPCI. We compared these with data from 108 patients with STEMI treated with PPCI in the prior year from February 1, 2018, to January 31, 2019 (N=108). These 7 patients did not suffer from COVID-19 infection, and 6 out of 7 presented to our hospital during regular work hours (8 am–8 pm weekdays, excluding public holidays). The Table shows numerically longer median times in all components when compared with historical data from the prior year. The largest time difference was in the time from symptom onset to first medical contact. Circulation: Cardiovascular Quality and Outcomes

TL;DR: A recommendation for transparent and structured reporting of ML analysis results specifically directed at clinical researchers and a list of key reporting elements with examples that can be used as a template when preparing and submitting ML-based manuscripts for the same audience are provided.
Abstract: Use of machine learning (ML) in clinical research is growing steadily given the increasing availability of complex clinical data sets. ML presents important advantages in terms of predictive performance and identifying undiscovered subpopulations of patients with specific physiology and prognoses. Despite this popularity, many clinicians and researchers are not yet familiar with evaluating and interpreting ML analyses. Consequently, readers and peer-reviewers alike may either overestimate or underestimate the validity and credibility of an ML-based model. Conversely, ML experts without clinical experience may present details of the analysis that are too granular for a clinical readership to assess. Overwhelming evidence has shown poor reproducibility and reporting of ML models in clinical research suggesting the need for ML analyses to be presented in a clear, concise, and comprehensible manner to facilitate understanding and critical evaluation. We present a recommendation for transparent and structured reporting of ML analysis results specifically directed at clinical researchers. Furthermore, we provide a list of key reporting elements with examples that can be used as a template when preparing and submitting ML-based manuscripts for the same audience.

TL;DR: Housing is a prominent social determinant of cardiovascular health and well-being and should be considered in the evaluation of prevention efforts to reduce and eliminate racial/ethnic and socioeconomic disparities.
Abstract: Cardiovascular disease disparities are shaped by differences in risk factors across racial and ethnic groups. Housing remains an important social determinant of health. The objective of this statement is to review and summarize research that has examined the associations of housing status with cardiovascular health and overall health. PubMed/Medline, Centers for Disease Control and Prevention data, US Census data, Cochrane Library reviews, and the annual Heart Disease and Stroke Statistics report from the American Heart Association were used to identify empirical research studies that examined associations of housing with cardiovascular health and overall well-being. Health is affected by 4 prominent dimensions of housing: stability, quality and safety, affordability and accessibility, and neighborhood environment. Vulnerable and underserved populations are adversely affected by housing insecurity and homelessness, are at risk for lower-quality and unsafe housing conditions, confront structural barriers that limit access to affordable housing, and are at risk for living in areas with substandard built environment features that are linked to cardiovascular disease. Research linking select pathways to cardiovascular health is relatively strong, but research gaps in other housing pathways and cardiovascular health remain. Efforts to eliminate cardiovascular disease disparities have recently emphasized the importance of social determinants of health. Housing is a prominent social determinant of cardiovascular health and well-being and should be considered in the evaluation of prevention efforts to reduce and eliminate racial/ethnic and socioeconomic disparities.
TL;DR: In this article, the American Heart Association provides rationale for the widespread adoption of rapid diet screener tools in primary care and relevant specialty care prevention settings, discuss the theory and practice-based criteria of a rapid diet assessment and counseling in clinical settings, review existing tools, and discuss opportunities and challenges for integrating a rapid Diet Screener tool into clinician workflows through the electronic health record.
Abstract: It is critical that diet quality be assessed and discussed at the point of care with clinicians and other members of the healthcare team to reduce the incidence and improve the management of diet-related chronic disease, especially cardiovascular disease. Dietary screening or counseling is not usually a component of routine medical visits. Moreover, numerous barriers exist to the implementation of screening and counseling, including lack of training and knowledge, lack of time, sense of futility, lack of reimbursement, competing demands during the visit, and absence of validated rapid diet screener tools with coupled clinical decision support to identify actionable modifications for improvement. With more widespread use of electronic health records, there is an enormous unmet opportunity to provide evidence-based clinician-delivered dietary guidance using rapid diet screener tools that must be addressed. In this scientific statement from the American Heart Association, we provide rationale for the widespread adoption of rapid diet screener tools in primary care and relevant specialty care prevention settings, discuss the theory- and practice-based criteria of a rapid diet screener tool that supports valid and feasible diet assessment and counseling in clinical settings, review existing tools, and discuss opportunities and challenges for integrating a rapid diet screener tool into clinician workflows through the electronic health record.

TL;DR: This article describes a doubly robust estimator which combines both models propitiously to offer analysts 2 chances for obtaining a valid causal estimate and demonstrates its use through a data set from the Lindner Center Study.
Abstract: Propensity score-based methods or multiple regressions of the outcome are often used for confounding adjustment in analysis of observational studies. In either approach, a model is needed: A model describing the relationship between the treatment assignment and covariates in the propensity score-based method or a model for the outcome and covariates in the multiple regressions. The 2 models are usually unknown to the investigators and must be estimated. The correct model specification, therefore, is essential for the validity of the final causal estimate. We describe in this article a doubly robust estimator which combines both models propitiously to offer analysts 2 chances for obtaining a valid causal estimate and demonstrate its use through a data set from the Lindner Center Study.

TL;DR: Although designed according to the best available evidence with input from various stakeholders and consistent with Centers for Medicare and Medicaid Services TC policies, the COMPASS model of TC was not consistently incorporated into real-world health care.
Abstract: Background The objectives of this study were to develop and test in real-world clinical practice the effectiveness of a comprehensive postacute stroke transitional care (TC) management program. Methods and Results The COMPASS study (Comprehensive Post-Acute Stroke Services) was a pragmatic cluster-randomized trial where the hospital was the unit of randomization. The intervention (COMPASS-TC) was initiated at 20 hospitals, and 20 hospitals provided their usual care. Hospital staff enrolled 6024 adult stroke and transient ischemic attack patients discharged home between 2016 and 2018. COMPASS-TC was patient-centered and assessed social and functional determinates of health to inform individualized care plans. Ninety-day outcomes were evaluated by blinded telephone interviewers. The primary outcome was functional status (Stroke Impact Scale-16); secondary outcomes were mortality, disability, medication adherence, depression, cognition, self-rated health, fatigue, care satisfaction, home blood pressure monitoring, and falls. The primary analysis was intention to treat. Of intervention hospitals, 58% had uninterrupted intervention delivery. Thirty-five percent of patients at intervention hospitals attended a COMPASS clinic visit. The primary outcome was measured for 59% of patients and was not significantly influenced by the intervention. Mean Stroke Impact Scale-16 (±SD) was 80.6±21.1 in TC versus 79.9±21.4 in usual care. Home blood pressure monitoring was self-reported by 72% of intervention patients versus 64% of usual care patients (adjusted odds ratio, 1.43 [95% CI, 1.21-1.70]). No other secondary outcomes differed. Conclusions Although designed according to the best available evidence with input from various stakeholders and consistent with Centers for Medicare and Medicaid Services TC policies, the COMPASS model of TC was not consistently incorporated into real-world health care. We found no significant effect of the intervention on functional status at 90 days post-discharge. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT02588664.
TL;DR: Major deficiencies in the old allocation system are reviewed, new changes in the new system are summarized, and their potential impact on the landscape of transplant medicine is discussed.
Abstract: In 1984, the National Organ Transplant Act was passed, which led to establishment of the Organ Procurement and Transplantation Network (OPTN) to ensure fair and equitable organ allocation (Figure). In 1986, OPTN contracted with the United Network for Organ Sharing (UNOS), a private nonprofit organization. Since its inception in 1988, the heart transplant (HT) allocation system of OPTN/UNOS has focused on listing patients based on severity of illness and time spent on a national waitlist. Initially, listing for HT was 2-tiered. With the introduction of left ventricular assist devices (LVADs), the allocation system was expanded to a 3-tiered system in 1998 (1A [high priority], 1B [intermediate priority], and 2 [low priority]) in an attempt to reduce waitlist time and mortality. In 2005, broader sharing rules were implemented to facilitate sharing over larger geographic areas, again in an attempt to reduce waitlist time for the most critically ill patients.1 With these changes, waitlist mortality initially declined.2 However, over the past decade, the HT waitlist has grown and at present lists over 4000 patients annually with ≈3000 HTs being performed nationally.3 By 2012, the number of patients listed as 1A and 1B had tripled, leading to a 3× higher waitlist mortality due to the longer waiting time for the most critically ill patients listed as 1A compared to those listed as 1B.4 In light of these emerging data and concerns that the existing system was suboptimal, the OPTN/UNOS heart subcommittee initiated the process of refining the heart allocation criteria, leading to a newly revised allocation policy in December 2016 that was finally implemented in October 2018.5 In this policy brief, we review major deficiencies in the old allocation system, summarize new changes, and discuss their potential impact on the landscape of transplant medicine.

TL;DR: To learn how a digital health platform could be customized to better serve lowincome patients and the supports necessary to facilitate mHealth adoption with sustained engagement, a novel mHealth application was evaluated.
Abstract: Applications accessible on digital platforms are increasingly popular in healthcare settings and have the potential to help patients engage with their health through monitoring of health behaviors (eg, physical activity, dietary habits) and physiological parameters (eg, heart rate, blood pressure, blood glucose). Some mobile health (mHealth) applications provide patients access to their medical data through patient portals and the ability to participate in real-world, pragmatic research using their smart devices.1 For low-income populations, however, unique barriers to mHealth utilization exist, amplifying the impact of social determinants of health. These barriers include fluency with mobile applications, limited health literacy, lack of empowerment, and historical mistrust of healthcare systems.2 As mHealth platforms play a larger role in healthcare delivery, the digital divide could serve to worsen health disparities.3,4 mHealth applications that are sensitive to the user needs of vulnerable populations have the potential to gain uptake in more diverse communities. Consideration to the visual and linguistic design of mHealth applications, along with how mHealth applications are introduced to patients, may increase adoption and acceptability. One promising intervention is the use of community health workers (CHWs), whose role is to support patients in their health-related needs and address social determinants of health, to promote greater usage and understanding of health applications, although this has not been studied. Accordingly, to better understand the real-world challenges and potential catalysts, including the use of CHWs, in increasing mHealth technology uptake in vulnerable populations, we evaluated the onboarding, perspectives, and experiences of underserved patients using a novel mHealth application. We aimed to learn how a digital health platform could be customized to better serve lowincome patients and the supports necessary to facilitate mHealth adoption with sustained engagement.

TL;DR: The Learning Collaborative developed a framework for a HF value-based payment model with a longitudinal focus on disease management and prevention and an optional track to prevent high-risk stage B pre-HF from progressing to stage C.
Abstract: Heart failure (HF) is a leading cause of hospitalizations and readmissions in the United States. Particularly among the elderly, its prevalence and costs continue to rise, making it a significant population health issue. Despite tremendous progress in improving HF care and examples of innovation in care redesign, the quality of HF care varies greatly across the country. One major challenge underpinning these issues is the current payment system, which is largely based on fee-for-service reimbursement, leads to uncoordinated, fragmented, and low-quality HF care. While the payment landscape is changing, with an increasing proportion of all healthcare dollars flowing through value-based payment models, no longitudinal models currently focus on chronic HF care. Episode-based payment models for HF hospitalization have yielded limited success and have little ability to prevent early chronic disease from progressing to later stages. The available literature suggests that primary care-based longitudinal payment models have indirectly improved HF care quality and cardiovascular care costs, but these models are not focused on addressing patients' longitudinal chronic disease needs. This article describes the efforts and vision of the multi-stakeholder Value-Based Models Learning Collaborative of The Value in Healthcare Initiative, a collaboration of the American Heart Association and the Robert J. Margolis, MD, Center for Health Policy at Duke University. The Learning Collaborative developed a framework for a HF value-based payment model with a longitudinal focus on disease management (to reduce adverse clinical outcomes and disease progression among patients with stage C HF) and prevention (an optional track to prevent high-risk stage B pre-HF from progressing to stage C). The model is designed to be compatible with prevalent payment models and reforms being implemented today. Barriers to success and strategies for implementation to aid payers, regulators, clinicians, and others in developing a pilot are discussed.

TL;DR: This work sought to measure the impact of the COVID-19 pandemic on emergency transfers for STEMI, stroke, and acute aortic emergencies within the regional health system.
Abstract: The COVID-19 pandemic has dramatically impacted healthcare delivery worldwide. In hotspot areas such as Wuhan, Lombardy, and New York City, the disease has forced hospitals to focus on COVID-19 patients. Anecdotal reports have suggested that the pandemic has led to a decrease in patients presenting to these hospitals with serious cardiovascular and neurologic diseases such as ST-elevation myocardial infarction (STEMI) and stroke. We sought to measure the impact of the COVID-19 pandemic on emergency transfers for STEMI, stroke, and acute aortic emergencies within our regional health system.

TL;DR: Although reimagining prior authorization requires collective action by all stakeholders, it may significantly reduce administrative burden for clinicians and payers while improving outcomes for patients.
Abstract: Utilization management strategies, including prior authorization, are commonly used to facilitate safe and guideline-adherent provision of new, individualized, and potentially costly cardiovascular therapies. However, as currently deployed, these approaches encumber multiple stakeholders. Patients are discouraged by barriers to appropriate access; clinicians are frustrated by the time, money, and resources required for prior authorizations, the frequent rejections, and the perception of being excluded from the decision-making process; and payers are weary of the intensive effort to design and administer increasingly complex prior authorization systems to balance value and appropriate use of these treatments. These issues highlight an opportunity to collectively reimagine utilization management as a transparent and collaborative system. This would benefit the entire healthcare ecosystem, especially in light of the shift to value-based payment. This article describes the efforts and vision of the multistakeholder Prior Authorization Learning Collaborative of the Value in Healthcare Initiative, a partnership between the American Heart Association and the Robert J. Margolis, MD, Center for Health Policy at Duke University. We outline how healthcare organizations can take greater utilization management responsibility under value-based contracting, especially under different state policies and local contexts. Even with reduced payer-mandated prior authorization in these arrangements, payers and healthcare organizations will have a continued shared need for utilization management. We present options for streamlining these programs, such as gold carding and electronic and automated prior authorization processes. Throughout the article, we weave in examples from cardiovascular care when possible. Although reimagining prior authorization requires collective action by all stakeholders, it may significantly reduce administrative burden for clinicians and payers while improving outcomes for patients.
