Procedural volume and outcomes in patients undergoing VA-ECMO support.

ABSTRACT:

Background

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used in patients with critical cardiopulmonary failure. To investigate the association between hospital VA-ECMO procedure volume and outcomes in a large, nationwide registry.

Methods

By using administrative data from the German Federal Health Monitoring System, we analyzed all VA-ECMO procedures performed in Germany from 2013 to 2016 regarding the association of procedural volumes with outcomes and complications.

Results

During the study period, 10,207 VA-ECMO procedures were performed; mean age was 61?years, 43.4% had prior CPR, and 71.2% were male patients. Acute coronary syndrome was the primary diagnosis for VA-ECMO implantation (n?=?6202, 60.8%). The majority of implantations (n?=?5421) were performed at hospitals in the lowest volume category (??50 implantations per year). There was a significant association between annualized volume of VA-ECMO procedures and 30-day in-hospital mortality for centers with lower vs. higher volume per year. Multivariable logistic regression showed an increased 30-day in-hospital mortality at hospitals with the lowest volume category (adjusted odds ratio 1.13, 95% confidence interval [CI] 1.01-1.27, p?=?0.034). Similarly, higher likelihood for complications was observed at hospitals with lower vs. higher annual VA-ECMO volume (adjusted odds ratio 1.46, 95% CI 1.29-1.66, p?=?0.001).

Conclusions

In this analysis of more than 10,000 VA-ECMO procedures for cardiogenic shock, the majority of implantations were performed at hospitals with the lowest annual volume. Thirty-day in-hospital mortality and likelihood for complications were higher at hospitals with the lowest annual VA-ECMO volume.

Project description:Systemic inflammation is a key characteristic of sepsis but also also in non-infectious conditions such as post-cardiac arrest syndrome. Cytokine adsorption and extracorporeal membrane oxygenation are emerging therapies applied in these critically ill patients, but the experience with their concurrent use is limited. We evaluated cytokine adsorption in critically ill patients requiring support with either veno-venous (vv) or veno-arterial (va) extracorporeal membrane oxygenation (ECMO) support and hypothesized that adsorber incorporation into the ECMO circuit was technically feasible and not associated with imminent risk. We analyzed data from the first six cases of a prospective single-center registry of patients undergoing veno-venous (vv) or veno-arterial (va) ECMO therapy. While in most published cases cytokine adsorbers were inserted into a hemofiltration circuit, we directly incorporated the adsorber into the ECMO circuit without interruption of continuous ECMO support. We observed no relevant side effects attributable to cytokine adsorption. Thirty-day mortality was 83% (predicted mortality 87%), indicating that the decision for adding cytokine adsorption may have been considered as an ultima ratio decision in severe cases with poor prognosis. Vasopressor or inotrope use, lactate level, and fluid balance did not change significantly when comparing pre- vs. post-cytokine adsorption values. Interestingly, the real-time course of the mentioned three surrogate parameters remained unaltered in all but two cases, regardless of cytokine removal. Beneficial effects of cytokine adsorption are plausible in two va-ECMO-treated patient, where increasing lactate began to drop after initiation of cytokine adsorption. Taken together, these data suggest that incorporation of cytokine adsorption into the management of critically ill patients requiring continued ECMO support is feasible and easy to handle. Whether cytokine removal improves clinical outcome in ECMO-treated patients should now be investigated in randomized controlled trials.

Project description:AimsPrimary graft dysfunction (PGD) is a feared complication after heart transplantation (HTX). HTX patients frequently receive veno-arterial extracorporeal membrane oxygenation (VA-ECMO) until graft recovery. Long-term mortality of patients weaned from VA-ECMO after HTX is comparable with non-ECMO patients. However, impact on quality of life is unknown. This study investigated days alive and out of hospital (DAOH) as patient-centred outcome in HTX patients at 1 year after surgery.Methods and resultsThis retrospective single-centre cohort study included patients who underwent HTX at the University Hospital Düsseldorf, Germany, from 2010 to 2020. Main exposure was VA-ECMO due to PGD. VA-ECMO and non-VA-ECMO patients were compared regarding the primary endpoint DAOH at 1 year after HTX. Subgroup analysis for patients weaned from VA-ECMO was performed. In total, 144 patients were included into analysis; 1 year mortality was significantly lower in non-ECMO patients [non-ECMO 14.3% (14/98) vs. VA-ECMO 34.8% (16/46), adjusted hazard ratio: 0.32, 95% confidence interval: 0.15-0.74; P = 0.002]. Mortality did not differ significantly between patients weaned from VA-ECMO and non-ECMO patients [non-ECMO 14.3% (14/98) vs. VA-ECMO (weaned) 18.9% (7/37), adjusted hazard ratio: 0.72, 95% confidence interval: 0.27-1.90; P = 0.48]. DAOH were significantly higher in non-ECMO patients compared with VA-ECMO patients and patients weaned from VA-ECMO [non-ECMO vs. VA-ECMO: median 310 (inter-quartile range 277-327) days vs. 243 (0-288) days; P < 0.0001; non-ECMO vs. VA-ECMO (weaned): 310 (277-327) days vs. 253 (208-299) days; P < 0.0001]. These results were still significant after multivariable adjustment with forced entry of predefined covariables.ConclusionsDespite similar survival rates, VA-ECMO due to PGD has a relevant life impact as defined by DAOH in the first year after HTX. As a more patient-centred endpoint, DAOH may contribute to a more comprehensive assessment of outcome in HTX patients.
