Clinical Trial Summary

The purpose of this study is to evaluate the use of VAD Care App in an out-patient mechanical circulatory support program. The specific aim for this pilot study is to obtain preliminary efficacy data of the VAD Care App as a self-management tool for patients with long-term LVADs. A randomized control trial will be employed to establish preliminary estimates of the effects of the App on the following outcomes: self-efficacy and adherence to the LVAD care regimen; LVAD-related complications and health care utilization [e.g., hospital re-admission]; overall health status and quality of life. The duration of the study is 6 months.

Description:

About 250,000 of 5.8 million Americans are suffering from an advanced or end-stage heart failure. Generally, these individuals require a heart transplant or a mechanical circulatory support such as a left-ventricular assist device (LVAD). LVAD is implanted to liberate patients from crippling symptoms of heart failure, or in some cases avert imminent death. However, maintaining health and improving quality of life (QOL) depend on a "trouble-free" LVAD. Despite the refinement in circulatory support technology, many patients and their family caregivers still face challenges in managing the LVAD in home settings. The LVAD home-care regimen comprise of complex technical and non-technical tasks and procedures that must be implemented frequently and consistently. During the first 6 months following hospital discharge, patients/caregivers generally exhibit low levels of confidence (i.e., self-efficacy) in managing the tasks/procedures. This problem appears to contribute to low adherence to the regimen and poor outcomes. The current self-management processes include provision of instructional manuals and logs for vital signs, LVAD parameters, etc. To address this problem, the research team developed a mobile phone VAD Care App as a self-management tool. The app will aid and may ease patients/caregivers' problems in managing the complexity of the home-care regimen. The app offers patients/caregivers with (a) daily reminders about the tasks/procedures to be performed, (b) videoconferencing feature to communicate with healthcare providers about LVAD and health issues, and (c) on-line LVAD training/education. The prototype of the app was tested by 16 patients and caregivers. Results included ease of use and high acceptability and competency rates among users.The specific aim for the present study is to obtain preliminary efficacy data of the care app as self-management tool in patients with a long-term LVAD. This study will employ a randomized control trial to establish preliminary estimates of the effects of the care app on the following: self-efficacy and adherence to the LVAD home-care regimen; LVAD-related complications and healthcare utilizations; overall health status and QOL. A total of 40 patients (with caregivers) will be recruited. There will be 20 patients allocated in the control (usual care) and experimental (usual care + VAD Care App) groups. Data collection will be performed during pre-hospital discharge (baseline) and at 1, 3 and 6 months post discharge using self-administered questionnaires, chart reviews, interviews, and retrieval of historical data of the care app. Descriptive and inferential statistical procedures will be employed for data analysis. The outcome of this pilot will inform the next stages of investigations that are crucial for transforming LVAD self-management processes and improving outcomes.

Related Conditions & MeSH terms

• Heart Failure

Intervention

Device:
• Mobile phone app (VAD Care App)
VAD Care App is a novel self-management tool being tested for patients with implantable LVADs. The app has daily "push notifications (alerts)," cues for daily self-management tasks, two-way communication using text messages and videoconferencing (virtual clinic), and links to LVAD self-management skills and videos easily accessible for self-management skill review.

Other:
• Usual LVAD Care
Routine clinic follow-up visits over 6 months. Patients and caregivers will both receive self-management education post discharge and as needed throughout the duration of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Health-related Quality of Life	Measured with the Kansas City Cardiomyopathy Questionnaire. A self-administered instrument consisting 23 items yielding a minimum and maximum values of 0 to 100 (overall summary score). Higher scores mean a better quality of life (i.e., a better outcome).	Baseline (T0), 1 month (T1), 3 (T2) months, and 6 months post hospital discharge.
Secondary	Self-efficacy	Measured with the LVAD Patient Self-Efficacy Scale. A self-administered instrument consisting 20 items with possible minimum and maximum values of 0 to 100 (standardized score). Higher scores mean a better self-efficacy (confidence) for managing daily LVAD care regimen (i.e., better outcome).	Baseline (T0), 1 month (T1), 3 (T2) months, and 6 months post hospital discharge.
Secondary	Health Status	Measured with PROMIS Global Health Short Form v1. This self-administered instrument consisted of 10 items with possible minimum and maximum values of 10 to 50 (sum scores). Higher sum scores mean a better health status (i.e., better outcome).	Baseline (T0), 1 month (T1), 3 (T2) months, and 6 months post hospital discharge.
Secondary	Adherence	Measured with LVAD Patient Home Management Adherence Scale. This self-administered instrument consisted 9 items with possible minimum and maximum values of 0 to 100 (standardized score). Higher sum scores mean a better adherence to daily LVAD care (i.e., a better outcome)	1 month (T1), 3 months (T2), and 6 months (T3) post hosp discharge.
Secondary	Complications	Number/frequency of complications were collected and recorded on an LVAD-related Complications Tracking Form. Data collections took place from day 0 to months 6 post hospital discharge. Minimum and maximum values were 0 to any possible values. Higher number of complications mean a worse outcome.	1 month (T1), 3 months (T2), and 6 months (T3) post hosp discharge.
Secondary	Hospital Readmission	Number/frequency of unplanned hospitalizations were recorded on LVAD Hospital Readmission Form. All-cause of unplanned hospitalization/readmission were collected from day 0 to 6 months post hospital discharge.	1 month (T1), 3 months (T2), and 6 months (T3) post hosp discharge.
