Moving the Dial on Heart Failure Patient Adherence Rates

Left ventricular ejection fraction: time to revise the metric?

In this paper, we highlight the prevalent misconception among patients regarding the normal value of left ventricular ejection fraction in cardiac function assessment. This misconception arises from the proportion dominance effect, wherein individuals tend to judge based on proportions rather than absolute values. We explain how this misunderstanding impacts patient demoralization and medical adherence, leading to worse clinical outcomes. To address this, the concept of "Left Ventricular Ejection Fraction - Proportion of Normal" is introduced, which adjusts left ventricular ejection fraction to a patient-specific normal range. This patient-centric approach aims to enhance comprehension, engagement, and adherence by conveying accurate information through the lens of proportions, thereby potentially improving clinical outcomes.

Definition of Polypharmacy in Heart Failure: A Scoping Review of the Literature

Patients with heart failure (HF) have a high prevalence of polypharmacy, which can lead to drug interactions, cognitive impairment, and medication non-compliance. However, the definition of polypharmacy in these patients is still inconsistent. The aim of this scoping review was to find the most common definition of polypharmacy in HF patients. We conducted a scoping review searching Medline, Embase, CINAHL, and Cochrane using terms including polypharmacy, HF and deprescribing, which resulted in 7,949 articles. Articles without a definition of polypharmacy in HF patients and articles which included patients < 18 years of age were excluded; only 59 articles were included. Of the 59 articles, 49% (n = 29) were retrospective, 20% (n = 12) were prospective, 10% (n = 6) were cross-sectional, and 27% (n = 16) were review articles. Twenty percent (n = 12) of the articles focused on HF with reduced ejection fraction, 10% (n = 6) focused on HF with preserved ejection fraction and 69% (n = 41) articles either focused on both diagnoses or did not clarify the specific type of HF. The most common cutoff for polypharmacy in HF was five medications (59%, n = 35). There was no consensus regarding the inclusion or exclusion of over-the-counter medications, supplements, or vitamins. Some newer studies used a cutoff of 10 medications (14%, n = 8), and this may be a more practical and meaningful definition for HF patients.

A Pre-Post, Mixed-Methods Study to Pilot Test a Gamified Heart Failure Self-Care Education Intervention

Objective: Self-care is essential to improving heart failure patient outcomes. However, the knowledge and behaviours necessary for self-care decision making, such as symptom perception and management, are complex and require patient education. The objective of this study was to test the feasibility, acceptability, and potential effectiveness of a web-based, gamified heart failure patient education solution, Heart Self-Care Patient Education (HeartSCaPE), that used narrative and virtual reward gamification techniques. Materials and Methods: This mixed-methods study used a pre-post-test design with an embedded explanatory qualitative phase. Patients completed the Self-Care of Heart Failure Index, that measured self-care behaviour change and the Dutch Heart Failure Knowledge Scale, used to measure heart failure knowledge. Usability measures of HeartSCaPE were tracked using Google Analytics and the System Usability Scale. Results: Nineteen patients completed the study, with a subset of six participating in semi-structured interviews. We found increases in HF knowledge despite high baseline knowledge scores. Post-intervention self-reported HF self-care behaviours (maintenance, management and confidence), as measured by the Self-Care of Heart Failure Index, were also improved. Knowledge and self-care scores were not correlated. Participants also scored HeartSCaPE as highly usable. In interviews, participants described valuing the opportunity to practice self-care decision-making. There were mixed opinions regarding the use of virtual rewards. Conclusion: We found that a gamified web-based solution that uses narrative and reward-based gamification techniques has the potential to improve HF patient knowledge and self-care. Further research is needed to confirm the study's clinical benefits and address technology literacy inequities.

Democratizing Global Health Care Through Scalable Emergent (Beyond the Mobile) Wireless Technologies

Advances in mobile phone technologies coupled with the availability of modern wireless networks are beginning to have a marked impact on digital health through the growing array of apps and connected devices. That said, limited deployment outside of developed nations will require additional approaches to collectively reach the 8 billion people on earth. Another consideration for development of digital health centered around mobile devices lies in the need for pairing steps, firmware updates, and a variety of user inputs, which can increase friction for the patient. An alternate, so-called Beyond the Mobile approach where medicaments, devices, and health services communicate directly to the cloud offers an attractive means to expand and fully realize our connected health utopia. In addition to offering highly personalized experiences, such approaches could address cost, security, and convenience concerns associated with smartphone-based systems, translating to improved engagement and adherence rates among patients. Furthermore, connecting these Internet of Medical Things instruments through next-generation networks offers the potential to reach patients with acute needs in nonurban regions of developing nations. Herein, we outline how deployment of Beyond the Mobile technologies through low-power wide-area networks could offer a scalable means to democratize digital health and contribute to improved patient outcomes globally.
