Abstract
Background & aims: Ascites is a frequent complication of cirrhosis. In intensive care units, initial hemodynamic assessment is frequently performed by echocardiography. This study evaluated the feasibility and usefulness of early hemodynamic assessment in the gastroenterology ward. Methods: This observational cohort study prospectively included all patients admitted to a teaching hospital’s gastroenterology unit for decompensated cirrhosis. A gastroenterologist with minimal training and an intensivist both performed an echocardiography exam. The primary outcome was inter-rater agreement and reliability for three echocardiography parameters: visual LVEF (Left Ventricular Ejection Fraction), subaortic VTI (velocity time integral) and E wave velocity. Secondary outcomes were agreement for presence of pleural effusion, description of 3 hemodynamics profiles (hypovolemic, hyperkinetic and intermediate), and 28-day mortality.Results: From March 2018 to March 2020, 53 patients were included. The median age was 62 years and 81% were men. Patients presented mostly advanced liver disease, with 43% Child-Pugh C and median MELD score of 15.2. The limits of agreement between intensivists and gastroenterologists for subaortic VTI were − 6.6 to 7.2 cm, and ranged from − 0.6 to 0.37 m.s-1 for E wave velocity. Clinically significant differences between intensivists and gastroenterologists were found in 22% for subaortic VTI and 24.5% for E wave velocity. Reliability was good for subaortic VTI (ICC: 0.79, 95% CI [0.58; 0.9;]) and moderate for E wave velocity (0.53, 95% CI [0.19; 0.74]). The three hemodynamics profiles had different prognosis, with a 28-day mortality for Hypovolemic, Intermediate and Hyperkinetic group of 31, 18, and 4%, respectively.Conclusion: Reliability of hemodynamic assessment by gastroenterologists was good, while agreement was unsatisfactory, advocating for further training. Transthoracic echocardiography can differentiate hypovolemia from hyperkinetic states. The role of transthoracic echocardiography in managing decompensated cirrhosis requires further study.Clinical trial number: NCT03650660.
