Seven UK participating centres agreed a standardised data collection pro-forma. Patients with chronic liver disease who were treated with rifaximin-α for secondary prevention of overt hepatic encephalopathy (OHE) were included.* Details of all causes of HE and emergency hospital admissions were requested at 3, 6 and 12 months before and after rifaximin-α initiation. Clinical data were recorded at baseline, at 3, 6 and 12 months before and after rifaximin-α initiation.
87% of patients (n=282) were taking concomitant lactulose.
*Some patients included were on 3 x 400 mg daily as this was prior to the launch of the UK licensed dose of TARGAXAN® 550 mg twice a day.

A retrospective, observational, multicentre study including 145 patients from 11 UK NHS centres. Conducted from Aug 2014 to Jun 2015.
AIM: To compare resource use in the 6 and 12 months before and after rifaximin-α initiation in UK patients with HE.
INCLUSION CRITERIA: Clinical diagnosis of HE. HE diagnosed prior to rifaximin-α initiation. Initiated on rifaximin-α at least 12 months prior data collection.
EXCLUSION CRITERIA: Rifaximin-α initiated at other hospitals. Medical records unavailable.

Details of hospitalisations and hospital visits were extracted from NHS Trust electronic databases. Analysis included only alive patients at the end of 6 and 12 month periods.
IMPRESS study was sponsored and funded by Norgine

Rifaximin-α initiation dose was 1100mg/day (licensed dose) in 30%, 1200 mg/day in 64%, and other doses in 6% of patients, respectively.
This study included patients started on rifaximin-a prior to the launch of TARGAXAN® 550mg bd. 82% of patients (n=119) were taking concomitant lactulose at baseline.
