Vasoactive-inotropic score and the prediction of morbidity and mortality after cardiac surgery.

ABSTRACT:

Background

The vasoactive-inotropic score (VIS) predicts mortality and morbidity after paediatric cardiac surgery. Here we examined whether VIS also predicted outcome in adults after cardiac surgery, and compared predictive capability between VIS and three widely used scoring systems.

Methods

This single-centre retrospective cohort study included 3213 cardiac surgery patients. Maximal VIS (VIS_max) was calculated using the highest doses of vasoactive and inotropic medications administered during the first 24 h post-surgery. We established five VIS_max categories: 0-5, >5-15, >15-30, >30-45, and >45 points. The predictive accuracy of VIS_max was evaluated for a composite outcome, which included 30-day mortality, mediastinitis, stroke, acute kidney injury, and myocardial infarction.

Results

VIS_max showed good prediction accuracy for the composite outcome [area under the curve (AUC), 0.72; 95% confidence interval (CI), 0.69-0.75]. The incidence of the composite outcome was 9.6% overall and 43% in the highest VIS_max group (>45). VIS_max predicted 30-day mortality (AUC, 0.76; 95% CI, 0.69-0.83) and 1-yr mortality (AUC, 0.70; 95% CI, 0.65-0.74). Prediction accuracy for unfavourable outcome was significantly better with VIS_max than with Acute Physiology and Chronic Health Evaluation II (P=0.01) and Simplified Acute Physiological Score II (P=0.048), but not with the Sequential Organ Failure Assessment score (P=0.32).

Conclusions

In adults after cardiac surgery, VIS_max predicted a composite of unfavourable outcomes and predicted mortality up to 1 yr after surgery.

Project description:ObjectivesThe 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.MethodsThis 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.ResultsA 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.ConclusionsVISmax 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:To empirically derive the optimal measure of pharmacologic cardiovascular support in infants undergoing cardiac surgery with bypass and to assess the association between this score and clinical outcomes in a multi-institutional cohort.Prospective, multi-institutional cohort study.Cardiac ICUs at four academic children's hospitals participating in the Pediatric Cardiac Critical Care Consortium during the study period.Children younger than 1 year at the time of surgery treated postoperatively in the cardiac ICU.None.Three hundred ninety-one infants undergoing surgery with bypass were enrolled consecutively from November 2011 to April 2012. Hourly doses of all vasoactive agents were recorded for the first 48 hours after cardiac ICU admission. Multiple derivations of an inotropic score were tested, and maximum vasoactive-inotropic score in the first 24 hours was further analyzed for association with clinical outcomes. The primary composite "poor outcome" variable included at least one of mortality, mechanical circulatory support, cardiac arrest, renal replacement therapy, or neurologic injury. High vasoactive-inotropic score was empirically defined as more than or equal to 20. Multivariable logistic regression was performed controlling for center and patient characteristics. Patients with high vasoactive-inotropic score had significantly greater odds of a poor outcome (odds ratio, 6.5; 95% CI, 2.9-14.6), mortality (odds ratio, 13.2; 95% CI, 3.7-47.6), and prolonged time to first extubation and cardiac ICU length of stay compared with patients with low vasoactive-inotropic score. Stratified analyses by age (neonate vs infant) and surgical complexity (low vs high) showed similar associations with increased morbidity and mortality for patients with high vasoactive-inotropic score.Maximum vasoactive-inotropic score calculated in the first 24 hours after cardiac ICU admission was strongly and significantly associated with morbidity and mortality in this multi-institutional cohort of infants undergoing cardiac surgery. Maximum vasoactive-inotropic score more than or equal to 20 predicts an increased likelihood of a poor composite clinical outcome. The findings were consistent in stratified analyses by age and surgical complexity.
