Type of study

EUPHAS 2 is a web-based patient registry for the collection of clinical data from patients with septic shock undergoing polymyxin B hemoperfusion therapy (PMX-HP, medical device Toraymyxin®, Toray Medical Ltd, Japan). The study is an observational cohort study divided into two phases, 1 and 2, a retrospective and prospective data collection, respectively.

Study period

Phase 1 was a retrospective data collection, which collected data from 357 patients in the period from January 2010 to December 2014 [1, 2]. Phase 2 is a prospective open-ended data collection started in January 2015.

Study objectives

EUPHAS 2 aims to strengthen the knowledge of the decision-making process leading to therapy prescription and to evaluate the effectiveness of the therapy. EUPHAS 2 also aims to identify subpopulations of patients who may benefit from this treatment more than others.

Study outcome measures

The collected data will include the following information: demographics, medical history, vital signs, diagnosis of septic shock, blood culture results, underlying diseases, infection source, treatment with other medical devices. Pre- and post-treatment variables include blood analysis, vital signs, vasoactive medication, diuresis, organ function scores, hemodynamic variables and results of blood gas analysis.
