BACKGROUND Several therapies are guideline-recommended to reduce mortality in patients with heart failure (HF) and reduced left ventricular ejection fraction, but the incremental clinical effectiveness of these therapies has not been well studied. We aimed to evaluate the individual and incremental benefits of guideline-recommended HF therapies associated… (More)

As telehealth plays an even greater role in global health care delivery, it will be increasingly important to develop a strong evidence base of successful, innovative telehealth solutions that can lead to scalable and sustainable telehealth programs. This paper has two aims: (1) to describe the challenges of promoting telehealth implementation to advance… (More)
BACKGROUND It has been argued that only 12% of adults have the necessary health literacy to manage their health care effectively, which can lead to difficulties in self-care activities, such as medication adherence. Prior research suggests that health literacy may influence knowledge, self-efficacy and self-care, but this has not been fully examined. … (More)
Background. Inadequate health literacy may be a barrier to gaining knowledge about heart failure (HF) self-care expectations, strengthening self-efficacy for self-care behaviors, and adhering to self-care behaviors over time. Objective. To examine if health literacy is associated with HF knowledge, self-efficacy, and self-care adherence longitudinally.… (More)
In patients with chronic heart failure, fluid retention (or hypervolemia) is often the stimulus for acute decompensated heart failure that requires hospitalization. The pathophysiology of fluid retention is complex and involves both hemodynamic and clinical congestion. Signs and symptoms of both hemodynamic and clinical congestion should be assessed… (More)
This paper describes impedance technique and device types, discusses hemodynamic data parameters that are available, discusses the differences between impedance cardiography and data that are derived from invasive pulmonary artery catheters, and explains how nurses can apply bioimpedance cardiography in a variety of patient populations.
BACKGROUND The theory of middle managers' role in implementing healthcare innovations hypothesized that middle managers influence implementation effectiveness by fulfilling the following four roles: diffusing information, synthesizing information, mediating between strategy and day-to-day activities, and selling innovation implementation. The theory also… (More)
