I have never used the Vision, but I googled it and looks like the FDA did a carryover study on it. I attached it. It is from 2019, sorry. Maybe you can find something more current. Good luck.

Yes, nationally in the UK, via BSH Guidelines.

It is with immense regret that I have to say that I learned yesterday that Dr Patricia Tippett died at the age of 93 on 1st August 2023.

I first met Pat in the early 1970's, when I was a callow youth who had just left school and was working at the IBGRL when it was in Gatliff Road in London (when Dr Kenneth Goldsmith was the Director) and Pat was working in the opposite building in the MRC Blood Group Unit, then under Drs Rob Race and Ruth Sanger.

Pat is probably most famous for her work on the Rh Blood Group System, including categorising the then know Partial D types and for realising that the RH genes were twofold; namely RHD and RHCE.
She was. of course, one of the greats, but was as friendly to this callow youth as I started out in the profession, as she was to everyone who were already greats within the field.

May she rest in peace.

Our Red Cross just informed us that it will discontinue providing CPDA-1 rbc.  We primarily used it to provide volume reduced red cells to pediatric patients under 3 years of age.  We will volume reduce AS-1 or AS-3 by centrifugation or washing (Terumo 2991) instead.  Probably unnecessary for most patients, but this is a long standing practice here, and it doesn't seem worthwhile trying to adjust pediatric practice in this regard.  Most patients do not need the additional volume provided by the anticoagulant-preservative in AS-1, etc., and avoiding unnecessary volume is a reasonable goal in many patients. 
There is no inherent virtue to CPDA-1 vs. AS-1 and similar solutions, and rbc preservation is slightly better in AS-1/AS-3 by in vitro metrics.  There is absolutely no factual basis for using CPD-A1 in preference to AS-1, etc. in pediatrics.  Purely expert opinion and probably unduly conservative.
 
I've attached a nice presentation by Dr. Saifee at the University of Washington, who createdAdditive solution AS-1 in Children Univ. Washington presentation Dec 2021.pptx it to educate her colleagues about using AS-1 instead of CPDA-1.

How do you even know the patient is who they say they are?  We have had a few instances where a person using another's ID and insurance was caught because of mismatching BB records.
