During the Ebola outbreak in Western Africa between 2014 and 2015, data was systematically collected by clinicians, at Ebola Treatment Units (ETUs) operated by International Medical Corps, on the treatments provided to patients with Ebola Virus Disease (EVD) and their mortality outcomes. In this study, we investigate the causal effects of intravenous fluid (IVF) treatment on mortality outcome in EVD patients receiving care at five ETUs from two countries during the epidemic. Using causal inference methods, we match EVD patients who received IVF treatment to those that did not based on their propensity score (the probability of receiving treatment) and their viral load. Results allude to increased survival rates from IVF treatment for Ebola patients with a low viral load, however, increased mortality rates resulting from IVF treatment for Ebola patients with a high viral load. Future work will extend this investigation into a time dependent analysis of IVF treatment controlling for initiation time and duration time using marginal structural models.
