A dimensional concept analysis on managing life with a left ventricular assist device

To describe management of life with a left ventricular assist device (LVAD) by patients and caregivers and to determine the fit of self- and family management as a guiding concept in LVAD research.

We applied dimensional analysis techniques to this concept analysis, beginning with a literature search (2010-25) of PubMed, CINAHL, Embase, PsycINFO, and Web of Science. Two reviewers screened and analysed 28 articles capturing perspectives on daily LVAD management among patients, caregivers, and healthcare professionals. Fourteen studies were qualitative, 12 were quantitative, and 2 were mixed methods. We identified five dimensions of patient and family management of LVAD therapy: patient facilitators and barriers; caregiver facilitators and barriers; processes of self- and family management; clinician facilitators and barriers/processes; and outcomes. These dimensions align with the concept of self- and family management and with core components of the Middle Range Theory of Self- and Family Management of Chronic Illness.

This dimensional concept analysis advances understanding of managing life with an LVAD by clarifying the collaborative roles of patients, caregivers, LVAD coordinators, and other healthcare professionals. Our analysis supports the use of self- and family management as a guiding concept and the application of the Middle Range Theory of Self- and Family Management of Chronic Illness in LVAD research. A new conceptual definition of LVAD self- and family management reflects this theoretical grounding. Our work offers direction for future research, clinical practice, and education aimed at improving outcomes for patients and caregivers managing life with an LVAD.
