Digital Health Interventions for Heart Failure Management in Underserved Rural Areas of the United States: A Systematic Review of Randomized Trials

An interactive visualization dashboard for predicting the effect of sacubitril/valsartan initiation in patients with heart failure

BACKGROUND

Sacubitril/valsartan (S/V) reduces mortality and hospitalization rates in patients with heart failure with reduced ejection fraction (HFrEF), but low adherence remains a challenge. Early initiation of S/V is recommended, yet no practical tool currently exists to effectively communicate its benefits to outpatients or assess patient stability before S/V initiation during hospitalization.

METHODS

We collected data retrospectively from 527 HFrEF patients who started S/V between March 2017 and January 2020 at the National Taiwan University Hospital, with follow-up through September 2022. A modern stepwise variable selection approach was applied to fit the optimal Cox's proportional-hazards model to address nonlinear covariate effects and potential multicollinearity. Penalized smoothing splines were used to visualize nonlinear effects and identify cutoff values for continuous covariates. The model was then integrated into an interactive Streamlit dashboard for real-time simulation and risk prediction based on patient-specific covariates.

RESULTS

We identified 20 key variables - 12 associated with increased risk and 8 conferring protective effects. Some variables presented actionable cutoff values. The predictive model helped estimate individualized hazard ratios and covariate-adjusted survival curves, which serve as both a patient engagement platform in outpatient settings and a practical tool for physicians to assess inpatient stability before initiating S/V.

CONCLUSION

Our interactive visualization dashboard can potentially improve medication adherence and clinical outcomes by involving patients in their treatment journey and facilitating more informed decision-making. A pragmatic clinical trial is currently underway to further evaluate the dashboard's clinical utility and effectiveness in both outpatient and inpatient environments.

Leveraging Mobile Health and Wearable Technologies for the Prevention and Management of Atherosclerotic Cardiovascular Disease

PURPOSE OF REVIEW

This review aims to assess the role of mobile health (mHealth) interventions and wearable technologies in the prevention and management of atherosclerotic cardiovascular disease (ASCVD). We sought to explore the benefits, challenges, and equity implications of these digital health modalities, with a focus on improving patient outcomes and reducing ASCVD risk.

RECENT FINDINGS

Recent studies have shown that mHealth interventions and wearable devices effectively promote healthy behaviors, offer real-time physiological monitoring, and aid in the early prevention of ASCVD by targeting key risk factors such as metabolic syndrome and sedentary lifestyles. These technologies hold great potential for improving patient engagement and enabling timely interventions. However, challenges such as technological constraints, high costs, and gaps in digital literacy significantly hinder their broader adoption, particularly among disadvantaged populations. In summary, our findings highlight the critical need for accessible, affordable, and inclusive digital health solutions to prevent and manage ASCVD, promoting more equitable healthcare delivery. To maximize these benefits, future research should focus on harnessing artificial intelligence and digital markers to improve early event prediction and develop personalized preventive strategies.

Interventions to Improve Health Among Refugees in the United States: A Systematic Review

Refugees arriving to the U.S. experience a high burden of both communicable and non-communicable diseases. There is a potential to improve health outcomes for refugees through well-developed, comprehensive interventions, but the effectiveness of such interventions is poorly understood. The purpose of this review is to identify, characterize and evaluate the effectiveness of patient-level healthcare interventions for U.S. refugee populations. We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Medline via PubMed, Web of Science, Embase, and CINAHL were searched for articles that included a population of refugees of any age, included an intervention aimed at improving health, included an evaluation of the intervention's outcomes, and were conducted in the U.S. from 2000 to 2022. Thirty-seven studies were included, and we identified three main intervention modalities: healthcare provision/management, resource provision, and education. Interventions targeted general health, infectious disease, women's health, diet/exercise, health literacy, oral health, diabetes, family health, and substance use. The outcomes measured included knowledge, satisfaction, behavioral outcomes, and physical health markers. This review demonstrates that a few health conditions, namely tuberculosis, have been addressed with large-scale, sustained interventions. Other conditions (general health and women's health) have been addressed through piecemeal, short-term interventions. The evaluation of interventions often focuses on knowledge or satisfaction rather than health or behavior change outcomes. Future work should focus on the best strategies for developing sustainable interventions that meet the needs of the diverse population of refugees in the U.S.

Bridging the Gap: How Accounting for Social Determinants of Health Can Improve Digital Health Equity in Cardiovascular Medicine

PURPOSE OF REVIEW

In this review, we discuss the importance of digital health equity and how social determinants of health (and intersectionality with race, ethnicity, and gender) affect cardiovascular health-related outcomes in digital health trials. We propose strategies to improve digital health equity as we move to a digitally-connected world for healthcare applications and beyond.

RECENT FINDINGS

Digital health has immense promise to improve population health by reaching individuals in their homes, at their preferred times. However, initial data demonstrate decreased patient engagement and worse cardiovascular outcomes for racial and ethnic minorities, leading to unequal uptake of digital health technologies. In addition, while women generally have higher uptake of technology, they are less likely to be referred by clinicians for digital health interventions. We highlight several exemplar trials and analyze their methodology for replication in future digital health research. The promise of digital health equity has not been reached due to exclusionary practices. Specific focus must be placed on societal/governmental policies that enable digital inclusion, particularly of racial and ethnic minority populations and women, to ensure that the expansion of digital health technologies does not exacerbate existing health disparities.

Digital health as a tool for patient activation and improving quality of care for heart failure

The clinical and economic impact of heart failure (HF) is immense and will continue to rise due to the increasing prevalence of the disease. Despite the availability of guideline-recommended medications that improve mortality, reduce hospitalizations, and enhance quality of life, there are major gaps in the implementation of such care. Quality improvement interventions have generally focused on clinicians. While certain interventions have had modest success in improving the use of heart failure medications, they remain insufficient in optimizing HF care. Here, we discuss how patient-facing interventions can add value and supplement clinician-centered interventions. We discuss how digital health can be leveraged to create patient activation tools that create a larger, sustainable impact. Small studies have suggested the promise of digital tools for patient engagement and self-care, but there are also important barriers to the adoption of such interventions that we describe. We share key principles and strategies around the design and implementation of digital health innovations to maximize patient participation and engagement. By uniquely activating patients in their own care, digital health can unlock the full potential of both existing and new quality improvement initiatives to drive forward high-quality and equitable heart failure care.

Achieving Equitable Cardiovascular Care for All: ACC Board of Trustees Health Equity Task Force Action Plan

Advancements in cardiovascular (CV) disease management are notable, yet health inequities prevail, associated with increased morbidity and mortality noted among non-Hispanic African Americans in the United States. The 2002 Institute of Medicine Report revealed ongoing racial and ethnic health care disparities, spearheading a deeper understanding of the social determinants of health and systemic racism to develop strategies for CV health equity (HE). This article outlines the strategic HE approach of the American College of Cardiology, comprising 6 strategic equity domains: workforce pathway inclusivity, health care, data, science, and tools; education and training; membership, partnership, and collaboration; advocacy and policy; and clinical trial diversity. The American College of Cardiology's Health Equity Task Force champions the improvement of patients' lived experiences, population health, and clinician well-being while reducing health care costs-the Quadruple Aim of Health Equity. Thus, we examine multifaceted HE interventions and provide evidence for scalable real-world interventions to promote equitable CV care.

Digital versus non-digital health interventions to improve iron supplementation in pregnant women: a systematic review and meta-analysis

Objective

To investigate the effects of digital health interventions for improving adherence to oral iron supplementation in pregnant women.

Literature search

Five databases were searched from their inception to October 2023 with no date restrictions.

Study selection

Randomized controlled trials (RCTs) that assessed the effects of digital health interventions on adherence to oral iron supplementation (e.g., tablets and capsules) compared to non-digital health interventions for pregnant women were eligible.

Data synthesis

We calculated standardized mean differences (SMDs) and mean differences (MDs) with 95% confidence intervals (CIs) for continuous variables using the inverse variance method. We calculated odds ratios (OR) with 95%CI for categorical variables using the Mantel-Haenszel model. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The risk of bias of the included RCTs was assessed using the Cochrane risk of bias tool 2.0.

Results

Ten trials with 1,633 participants were included. Based on 7 trials, digital health interventions can improve objective adherence rate comparing with non-digital health interventions (1,289 participants, OR = 4.07 [2.19, 7.57], p < 0.001, I2 = 69%) in pregnant women. Digital health interventions can improve subjective adherence behavior comparing with non-digital health interventions (3 trials, 434 participants, SMD = 0.82 [0.62, 1.01], p < 0.001, I2 = 0%) in pregnant women. Based on 3 trials, digital health interventions can improve tablets consumption comparing with non-digital health interventions (333 participants, SMD = 1.00 [0.57, 1.42], p < 0.001, I2 = 66%) in pregnant women. Digital health interventions can improve hemoglobin level comparing with non-digital health interventions (7 trials, 1,216 participants, MD = 0.59 [0.31, 0.88], p < 0.001, I2 = 93%) in pregnant women.

Conclusion

Digital health interventions were effective at improving adherence to oral iron supplementation and hemoglobin levels in pregnant women.
