Abstract
❏ Sepsis (an infection associated with vital organ dysfunction) is an emergent
medical condition estimated to occur in about 30% of intensive care unit
(ICU) patients[1] and is responsible for 20% of all deaths worldwide[2]
❏ Transthoracic echocardiography (TTE; an imaging modality that uses
ultrasound technology to record heart structure and function) is widely used in
medical treatment [3]
❏ 28-day mortality (whether or not a patient dies within 28 days after receiving a
treatment) is a measure considered to closely approximate ICU mortality[4]
Objectives
❏ Assess and quantify the causal effect of receiving a TTE on the 28-day
mortality of ICU patients with sepsis
❏ Analyze treatment effect heterogeneity across patients
