Patient-Reported Issues Following Left Ventricular Assist Device Implantation Hospitalization

Mobile Health Intervention Contents and Their Effects on the Healthcare of Patients with Left Ventricular Assist Devices: An Integrative Review

Self-care in daily life is important for patients with a left ventricular assist device. Mobile health interventions that use an application, the cloud, or telemonitoring enable active health management. This study reviewed the literature on the contents of mobile health interventions for patients with left ventricular assist devices and their effects. We searched four electronic databases (CINAHL, Cochrane Library, EMBASE, and MEDLINE) and reference lists in May 2022. The search terms consisted of "heart-assist devices" and "residence characteristics," combined with "mobile applications," "telemonitoring," "medical informatics applications," "cell*," "app*," "smartphone," and "cloud." In total, seven studies were included in the review. Mobile health interventions included (1) self-management contents and (2) interactions between patient and healthcare providers. The mobile health device and patient's health management were evaluated as a measure of the effect. This review provides a unique understanding for leveraging mobile health interventions as an effective approach to improve healthcare among patients with left ventricular assist devices. Future mobile health intervention strategies targeting these patients should fully consider the patient's perspective. Furthermore, they should be designed and applied to help with long-term health management, accompanied by an evaluation of their effectiveness on self-care improvement.

Content Validity of the Left Ventricular Assist Device Bathing Assessment

Many institutions recommend modified bathing techniques for individuals with left ventricular assist devices (LVADs) due to infection risk. Although these techniques may be challenging for patients, there currently is no assessment to evaluate these skills and whether intervention programs have been successful. This article describes the development and content validation of the LVAD Bathing Assessment. The content validity index (CVI) process was used to determine the relevance of assessment items. Modified Kappa indices were calculated to account for the possibility of chance agreement among raters. Eight content validity experts rated each assessment item and provided feedback. The overall assessment and 44 of 47 individual items had excellent content validity (scale-level CVI [S-CVI] = 0.97; item-level CVI [I-CVI] > 0.78). Minor revisions were made based on feedback. Creation of an LVAD bathing assessment may improve care by identifying safety risks that may cause infection. Further studies for construct validation and reliability testing are needed.

A pilot clinical trial of a self-management intervention in patients with a left ventricular assist device

Self-management is a health behavior known to predict treatment outcomes in patients with multiple co-morbidities and/or chronic conditions. However, the self-management process and outcomes in the left-ventricular assist device (LVAD) population are understudied. This pilot randomized control trial (RCT) evaluated the feasibility of a novel "smartphone app-directed and nurse-supported self-management intervention" in patients implanted with durable LVADs. Assessments included behavioral (self-efficacy and adherence), clinical (complications), and healthcare utilization (unplanned clinic, emergency room (ER) visits, and re-hospitalization) outcomes, completed at baseline (pre-hospital discharge) and months 1, 3, and 6 post-hospital discharge. Intervention patients (n = 14) had favorable patterns/trends of results across study outcomes than control patients (n = 16). Notably, intervention patients had much lower complications and healthcare utilization rates than controls. For example, intervention patients had 2 (14.3%) driveline infections in 6 months while control patients had 3 (19.0%). Additionally, at month 3, intervention patients had 0% ER visits versus 36% of control patients. At month 6, the mean cumulative number of re-hospitalizations for the control group was higher (0.9 ± 0.93) than intervention (0.3 ± 0.61) group. Despite the small sample size and limitations of feasibility/pilot studies, our outcomes data appeared to favor the novel intervention. Lessons learned from this study suggest the intervention should be implemented for 6 months post-hospital discharge. Further research is needed including large and rigorous multi-center RCTs to generate knowledge explaining the mechanism of the effect of self-management on LVAD treatment outcomes.
