Ventricular assist devices: A review of psychosocial risk factors and their impact on outcomes

Background Psychosocial contraindications for ventricular assist devices (VADs) remain particularly nebulous and are driven by institution-specific practices. Our multi-institutional, multidisciplinary workgroup conducted a review with the goal of addressing the following research question: How are preoperative psychosocial domains predictive of or associated with postoperative VAD-related outcomes? Answers to this question could contribute to the development of treatment-specific (contra) indications for patients under consideration for mechanical devices.

Methods and Results We identified 5 studies that examined psychosocial factors and their relationship to postoperative VAD-related outcomes. Our results suggest that 3 psychosocial variables are possibly associated with VAD-related outcomes: depression, functional status, and self-care. Of the few studies that exist, the generalizability of findings is constrained by a lack of methodologic rigor, inconsistent terminology, and a lack of conceptual clarity.

Conclusions This review should serve as a call for research. Efforts to minimize psychosocial risk before device placement can only be successful insofar as VAD programs can clearly identify who is at risk for suboptimal outcomes.
