Reviews at least look at literature before making their recommendations - they are maybe opinion, but then they have an educated opinion!

I was asked by the Int Soc of Blood Transfusion (ISBT) to review the literature and present what the  "best evidence" was to their World Congress in Cape Town last year. My summary of the literature, (submitted for publication before the J Trauma Suppliment came out) came to pretty much the exact conclusions and recommendations they made in J Trauma June Suppliment.
(If anything, it was reassuring to me when I read the suppl that their conclusions were so close to my own)

If independant reviewers come to a similar opinion about available data, then there is surely something in that data! Also we must not forget that (unlike some propose) evidence-based medicine is NOT all about RCTs, rather about applying "best available evidence" to day-to-day  practice.

Karim, I'll send you my article (the document I submitted to them, published as ISBT Science Series 2006, Sept 1: 180 - 184) with it's references to your personal mail box and you are welcome to distribute if you feel it has merit.

Mark,

Thanks, but...

-Can J Surg: Dec 2005

This is a mathematical model

-J trauma suppl: June:2006

These are reviews/editorials and have little/no data

-J Trauma: Jan 2007

This has clinical data (hurrah!) but compares resolution of coagulopathy
before ICU to after ICU (ie. before patients stop bleeding to after patients
stop bleeding).

-Surg Commander Holcomb: prelim reports of a definitive 2007 paper out of
> Iraq, which has gone to press I am told (BTS representative)

This retrospective audit of combat casualty victims who receive at least 10
units of blood does show an improvement in survival for those who receive
lower ratios.

I'm not saying 1:1 is wrong at all, but considering how we discuss  the
merits of massive RCTs like NASCIS/CRASH/SAFE, is this now all we need to
change practice??

Anyway, I am still interested in getting a baseline view of how much blood
people are used to ordering for massive transfusions - especially the
general view of the list population at large.  If we do even get round to
trialling this, it will be important to establish a control arm that
accurately reflects current practice.  So:  6 units of blood has gone in,
how much FFP next?

Many thanks

Karim
