Patient decision-making regarding left ventricular assist devices : A multiple case study

Abstract

Objectives: To understand how patients make decisions regarding a left ventricular assist device (LVAD).

Design: A qualitative multiple case study design was used to explore the context and influence of individuals regarding patients' decision-making processes through: 1) detailed, in-depth interviews of those mostly involved in the patient's decision and 2) pertinent data including observations, medical records, educational information and physical artifacts. Data clusters and patterns of co-occurring codes were examined using thematic analysis.

Main outcome measures: Themes were extrapolated from individual case summaries to provide an in-depth analysis of each case and a cross-case analysis across the multiple cases. The predominant theme, consistent with other studies, was the salience of survival.

Findings: This case study approach revealed new themes beyond those of prior studies. Patients considered: 1) self-care management for patients without a caregiver, 2) acceptability and future expectations of the LVAD and 3) the role of nurses in eliciting patients' fears, values and preferences.

Conclusion: The patients' decision-making processes regarding an LVAD involve a cost-benefit analysis of the anticipated needs and consequences of the LVAD. Acceptability of the device is relevant to clinical practice and public policy. Nurses have a unique role in seeking patients' concerns, an essential component of shared decision-making.
