European Transfusion Practice and Outcome Study - Full Text View

Purpose

The aim of the ETPOS study is to describe differences in transfusion habits throughout Europe and to correlate these habits to perioperative outcome parameters. Special focus is put on the number of PRBCs (packed red blood cells) transfused and the ratio of PRBCs to other blood products or coagulation factors in the operating room. Furthermore the motivation of physicians to transfuse PRBC and blood products in the operating room will be investigated.

Primary Outcome Measures:

Amount of PRBC and blood products and coagulation factors transfused [ Time Frame: The Time point at which outcome measure is assessed is during surgery at Day 0 ] [ Designated as safety issue: No ]
Amount of packed red blood cells and blood products and coagulation factors: fresh frozen plasmas (FFPs), platelets (PTs) and tranexamic acid transfused

Secondary Outcome Measures:

Factors determining transfusion of PRBC and blood products in different regions of Europe [ Time Frame: The Time point at which outcome measure is assessed is during surgery at Day 0 ] [ Designated as safety issue: No ]
Reasons for transfusion of PRBC(packed red blood cells)and blood products in different regions of Europe
30-day mortality [ Time Frame: The Time point at which outcome measure is assessed is at Day 30 after Surgery ] [ Designated as safety issue: No ]
Assesses on Day 30 whether patient is still alive or has died between day zero (Surgery) day 30 after surgery
Unplanned admission to the ICU [ Time Frame: The Time point at which outcome measure is assessed is at Day 30 after Surgery ] [ Designated as safety issue: No ]
Assesses on day 30 whether the patient had a Unplanned admission to the Intensive care unit(ICU) following surgery (day 0) until the day 30
Type and frequency of usage of blood conserving techniques [ Time Frame: The Time point at which outcome measure is assessed is at Day 0, on Surgery Day ] [ Designated as safety issue: No ]

Estimated Primary Completion Date:	August 2013 (Final data collection date for primary outcome measure)

Detailed Description:

In European patients undergoing elective non-cardiac surgery receiving at least one PRBC(packed red blood cells) during their surgery it is proposed to:

Evaluate evidence of differences in the standard of peri-operative transfusion care in different healthcare systems within Europe, and the use of blood conserving techniques.
1. Evaluate the ratio of transfusion of PRBC to blood products in the operating room
2. Evaluate which factors determine transfusion of PRBC (is it patient's haemodynamics / haemoglobin threshold/ pressure from the surgeon / acute brisk bleeding / else) and blood products (ratio to PRBC / POC (point of care) monitoring/ per protocol/ else) in the operating room
Evaluate whether there are factors in transfusion therapy that are associated with outcome (in-hospital mortality and unplanned admission to ICU(Intensive Care Unit).)
