Association between vasoactive-inotropic score, morbidity and mortality after heart transplantation.

ABSTRACT:

Objectives

The aim of this study was to evaluate the association between vasoactive-inotropic score (VIS), calculated in the 24 h after heart transplantation, and post-transplant mortality and morbidity.

Methods

This was an observational single-centre retrospective study. Patients admitted to surgical intensive care unit after transplantation, between January 2015 and December 2018, were reviewed consecutively. VISmax was calculated as dopamine+ dobutamine+ 100 × epinephrine + 100 × norepinephrine + 50 × levosimendan + 10 × milrinone (all in µg/kg/min) + 10 000 × vasopressin (units/kg/min), using the maximum dosing rates of vasoactive and inotropic medications in the 24 h after intensive care unit admission. The primary outcome was mortality at 1 year post-transplant. The secondary outcomes included length of stay, duration of mechanical ventilation and inotropic support and the occurrence of septic shock, ventilator-associated pneumonia, bloodstream infection or renal replacement therapy.

Results

A total of 151 patients underwent heart transplantation and admitted to intensive care unit. The median VISmax was 39.2 (interquartile range = 19.4-83.0). VISmax was independently associated with 1-year post-transplant mortality, as well as recipient age [hazard ratio (HR) = 1.004, P-value = 0.013], recipient gender (female to male: hazard ratio = 2.23, P-value = 0.047) and combined transplantation (hazard ratio = 2.85, P-value = 0.048). There was a significant association between VISmax and duration of mechanical ventilation (P-value < 0.001), length of stay (P-value = 0.002), duration of infused inotropes (P-value < 0.001), occurrence of bloodstream infections, septic shocks, ventilation-acquired pneumonia and renal replacement therapy.

Conclusions

VISmax calculated during the first 24 h after postoperative intensive care unit admission in transplanted patients is independently associated with 1-year mortality. In addition, length of stay, duration of mechanical ventilation and infused inotropes increased with increasing VISmax.

Project description:OBJECTIVES:To assess the validity of Vasoactive-Inotropic Score as a scoring system for cardiovascular support and surrogate outcome in pediatric sepsis. DESIGN:Secondary retrospective analysis of a single-center sepsis registry. SETTING:Freestanding children's hospital and tertiary referral center. PATIENTS:Children greater than 60 days and less than 18 years with sepsis identified in the emergency department between January 2012 and June 2015 treated with at least one vasoactive medication within 48 hours of admission to the PICU. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:Vasoactive-Inotropic Score was abstracted at 6, 12, 24, and 48 hours post ICU admission. Primary outcomes were ventilator days and ICU length of stay. The secondary outcome was a composite outcome of cardiac arrest/extracorporeal membrane oxygenation/in-hospital mortality. One hundred thirty-eight patients met inclusion criteria. Most common infectious sources were pneumonia (32%) and bacteremia (23%). Thirty-three percent were intubated and mortality was 6%. Of the time points assessed, Vasoactive-Inotropic Score at 48 hours showed the strongest correlation with ICU length of stay (r = 0.53; p < 0.0001) and ventilator days (r = 0.52; p < 0.0001). On multivariable analysis, Vasoactive-Inotropic Score at 48 hours was a strong independent predictor of primary outcomes and intubation. For every unit increase in Vasoactive-Inotropic Score at 48 hours, there was a 13% increase in ICU length of stay (p < 0.001) and 8% increase in ventilator days (p < 0.01). For every unit increase in Vasoactive-Inotropic Score at 12 hours, there was a 14% increase in odds of having the composite outcome (p < 0.01). CONCLUSIONS:Vasoactive-Inotropic Score in pediatric sepsis patients is independently associated with important clinically relevant outcomes including ICU length of stay, ventilator days, and cardiac arrest/extracorporeal membrane oxygenation/mortality. Vasoactive-Inotropic Score may be a useful surrogate outcome in pediatric sepsis.

Project description:BackgroundThe purpose of this study is to evaluate the utility of vasoactive-inotropic score (VIS) in predicting outcomes after left ventricular assist device (LVAD) implantation and explore possible mechanisms of post-operative hemodynamic instability.MethodsRetrospective review was performed in 418 consecutive patients with LVAD implantation. VIS was calculated as dopamine + dobutamine + 10 × milrinone + 100 × epinephrine + 100 × norepinephrine (all μg/kg/min) + 10000 × vasopressin (U/kg/min) after initial stabilization in the operating room and upon arrival at the intensive care unit. The primary outcome was in-hospital mortality. The secondary outcomes were a composite of in-hospital mortality, delayed right ventricular assist device (RVAD) implantation, and continuous renal replacement therapy. The pre-operative biomarkers of inflammation, oxidative stress, endotoxemia and gut-derived metabolite trimethylamine-N-oxide (TMAO) were measured in a subset of 61 patients.ResultsMedian VIS was 20.0 (interquartile range 13.3-27.9). VIS was an independent predictor of in-hospital mortality (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.03-1.09, p < 0.001) and composite outcome (OR 1.03, 95% CI 1.01-1.06, p = 0.008). In-hospital mortality increased for each VIS quartile (0% vs 3.9% vs 7.6% vs 12.3%, p = 0.002). VIS was superior to other established LVAD risk models as a predictor of in-hospital mortality (area under the curve 0.73, 95% CI 0.64-0.82). The optimal cut-off point for VIS as a predictor of in-hospital mortality was 20. Pre-operative hemoglobin level was the only independent predictor of VIS ≥ 20 (p = 0.003). Patients with a high VIS were more likely to have elevated TMAO pre-operatively (53.6% vs 25.8%, p = 0.03).ConclusionsA high post-operative VIS is associated with adverse in-hospital outcomes and is a better predictor of in-hospital mortality compared with existing LVAD risk models. Whether early hemodynamic stabilization using RVAD may benefit patients with a high VIS remains to be investigated.
