Abstract

<p><strong>BACKGROUND: </strong>Paracorporeal continuous-flow ventricular assist devices (PCF VAD) are increasingly used in pediatrics, yet PCF VAD resource utilization has not been reported to date.</p>

<p><strong>METHODS: </strong>Pediatric Interagency Registry for Mechanically Assisted Circulatory Support (PediMACS), a national registry of VADs in children, and Pediatric Health Information System (PHIS), an administrative database of children's hospitals, were merged to assess VAD implants from 19 centers between 2012 and 2016. Resource utilization, including hospital and intensive care unit length of stay (LOS), and costs are analyzed for PCF VAD, durable VAD (DVAD), and combined PCF-DVAD support.</p>

<p><strong>RESULTS: </strong>Of 177 children (20% PCF VAD, 14% PCF-DVAD, 66% DVAD), those with PCF VAD or PCF-DVAD are younger (median age 4 [IQR 0-10] years and 3 [IQR 0-9] years, respectively) and more often have congenital heart disease (44%; 28%, respectively) compared to DVAD (11 [IQR 3-17] years; 14% CHD); p &lt; 0.01 for both. Median post-VAD LOS is prolonged ranging from 43 (IQR 15-82) days in PCF VAD to 72 (IQR 55-107) days in PCF-DVAD, with significant hospitalization costs (PCF VAD $450,000 [IQR $210,000-$780,000]; PCF-DVAD $770,000 [IQR $510,000-$1,000,000]). After adjusting for patient-level factors, greater post-VAD hospital costs are associated with LOS, ECMO pre-VAD, greater chronic complex conditions, and major adverse events (p &lt; 0.05 for all). VAD strategy and underlying cardiac disease are not associated with LOS or overall costs, although PCF VAD is associated with higher daily-level costs driven by increased pharmacy, laboratory, imaging, and clinical services costs.</p>

<p><strong>CONCLUSION: </strong>Pediatric PCF VAD resource utilization is staggeringly high with costs primarily driven by pre-implantation patient illness, hospital LOS, and clinical care costs.</p>

Abstract

<p><strong>BACKGROUND: </strong>Few data exist on resource utilization with pediatric ventricular assist devices (VADs). We tested the hypothesis that device type and adverse events are associated with increased resource utilization in pediatric patients supported with VADs.</p>

<p><strong>METHODS AND RESULTS: </strong>The Pediatric Interagency Registry for Mechanically Assisted Circulatory Support, a national registry of VADs in patients &lt;19&nbsp;years old, and the Pediatric Health Information System, an administrative database, were merged. Univariate analysis was performed assessing the association of all factors with the total cost and length of stay first. Significant variables (&lt;0.05) were subjected to multivariable analysis. The study included 142 patients from 19 centers with VAD implants from October 2012 to June 2016. The median age was 9&nbsp;years (interquartile range [IQR] 2-15), 84 (59%) supported with a continuous-flow VAD. Overall median hospital costs were $750&nbsp;000 (IQR $539&nbsp;000 to $1&nbsp;100&nbsp;000) with a median hospital length of stay of 81&nbsp;days (IQR 54-128). On multivariable analysis, device type and postoperative complications were not associated with resource utilization. Factors associated with increased costs included patient age, lower-volume VAD center, being intubated, being on extracorporeal membrane oxygenation, number of complex chronic medical conditions, and length of stay. Among continuous-flow VAD patients, discharge to home before transplant versus remaining hospitalized was associated with lower hospital costs (median $600&nbsp;000 [IQR $400&nbsp;000 to $820&nbsp;000] versus median $680&nbsp;000 [IQR $500&nbsp;000 to $970&nbsp;000], =0.03).</p>

<p><strong>CONCLUSION: </strong>VADs in pediatric patients are associated with high resource utilization. Increased resource utilization was associated with lower-volume VAD centers, disease severity at VAD implantation, and the presence of complex chronic medical conditions. Further study is needed to develop cost-effective strategies in this complex population.</p>
