Shared care for patients with a left ventricular assist device: a scoping review

Left ventricular assist devices (LVADs) are increasingly implanted in patients with advanced heart failure. Currently, LVAD care is predominantly concentrated at specialized tertiary care hospitals. However, the increasing workload and logistical burden for implanting centres pose significant challenges to accessing care for individual patients in remote areas. An emerging approach to LVAD patient management is the use of a shared care model (SCM), which facilitates collaboration between implanting centres and local non-implanting hospitals. This scoping review explores and synthesizes the current scientific evidence on the use of SCMs in LVAD care management. Eligible studies were identified in EMBASE, PubMed MEDLINE, Web of Science, Cochrane and Google Scholar. Findings were synthesized in accordance with PRISMA-ScR guidelines. Of the 950 records screened, five articles met the inclusion criteria. Four review articles focused on the proposed benefits and challenges of using SCMs. Main benefits included improved patient satisfaction and continuity of care. Important challenges were initial education of non-implanting centre staff and maintaining competency. One prospective study showed that absence of LVAD-specific care was associated with impaired survival and higher rates of pump thrombosis and LVAD-related infections. The use of SCMs is a promising approach in the long-term management of LVAD patients. However, sufficient evidence about the impact of SCMs on patients and the healthcare system is not currently available. Standardized protocols based on prospective studies are needed to develop safe and effective shared care for LVAD patients.
