NCBI (PubMed) toolbar
If you use Google's toolbar, the NCBI toolbar is similar. Instead of choosing to search the web, news, images, etc., (as in Google), the NCBI toobar allows you to select from several databases (PubMed, gene, nucleotide, all). As in Google, you can also highlight your search terms.

Implementing new blood safety regulations in the UK
For example, they have decided that some activities currently done by hospital transfusion labs might be classified as "processing" under the new regulations and therefore can only be carried out by licensed "Blood Establishments" (blood suppliers - their National Blood Service) after 8 Nov. 2005. Processing includes pooling cryoprecipitate, irradiating components, splitting components, and washing red cells.
The result is that either hospital transfusion services will need to get licensed (like the blood supplier) or else the NBS has to do all the processing for them. There are also other implication for traceability, quality systems, training, and hemovigilance.
TraQ has been following events in the UK related to implementing the EU blood directive because Canada is in a somewhat similar situation. The main difference is that the Canadian standard that affects transfusion services (CSA Standard Z902-04) is not yet regulation. The Canadian Society for Transfusion Medicine (CSTM) has also revised its standards for hospital transfusion services to provide a user friendly equivalent of the CSA standards.

Usurpation of identity (more...)
We had a patient a few weeks ago who got into a fight while out with friends at a bar. He was brought into Emergency and crossmatched under
“Fred Flintstone”. He did not have a historical record so no one was the wiser.His friends even called him “Fred”. Who was to know?
Well,the police were notified and came to the hospital to investigate....Ooops! As he was about to go into the OR, a police officer recognized him as “Barney Rubble”. He was using a friend’s ID because he was well known to them and under house arrest!
All specimens were discarded, redrawn and retested. The record under the original name was expunged.

Dr. Jack Bowman (In Memoriam)
Dr. Jack Bowman, AABB Karl Landsteiner Memorial Award recipient, 2001, a transfusion medicine pioneer, and one of the world's leading experts in treating and preventing hemolytic disease of the newborn, died on May 22:
- John Maxwell Bowman (May 24, 1925 - May 22, 2005)
- Dr. B was group O Rh negative and often would donate his own blood for exchange or intrauterine transfusions (IUTs) when we were out of fresh O negs on the weekends
- His twin brother Bill wore a bow tie, making it easy to differentiate "bow tie Bill" from Dr. B
- Seeing him literally scurry about the donor room as he managed the plasmapheresis sessions of his "Rh ladies" who donated their anti-D for the production of Rh immune globulin. All of these women had had at least one baby die from HDN and at least one saved by an IUT managed by Dr. B. Their respect and affection for him was obvious to all.
- Getting the chance to work on many of Dr. B's projects, including monitoring anti-D production in Rh negative women who volunteered for the clinical trial of prenatal Rh immune globulin at 28 weeks gestation; monitoring the antibody titres of the women who donated anti-D for Rh immune globulin and were boosted periodically with D+ red cells; working as a go-fer during plasmapheresis of the "Rh ladies"
- Getting to donate anti-B (being group A) via plasmapheresis and experiencing the 5-minute transfusion of my cold autologous red cells
- Once when I came to Dr. B about a patient with a difficult serologic problem, he looked at me and said, "You tell me, Pat. You're the expert." As someone who believes that we recall life mainly as a series of short encounters, this is one of my defining moments. It was the first time that someone in a position of professional authority had told me that my knowledge and experience had value. Simple, but all too rare.
- Dr. B was the prototype of the busy professional who had far too much to do - university professor, medical director of a combined blood centre and transfusion service, director of another major laboratory (the "Rh Laboratory" pioneered by Bruce Chown and Marion Lewis), director of the Rh Institute, a pharmaceutical plant that developed intravenous Rh immune globulin (Win Rho), clinician who treated fetuses and newborns with HDN, husband and father.
Yet he was also the type of man who, years after I left the Red Cross, an organization with many technologists and nurses since it was not only the province's sole blood centre but also the transfusion service for all of Winnipeg, would never fail to recognize me at conferences and find time for a chat that showed he remembered.Besides the many mothers and children affected by his work, Dr. B will be missed by everyone who had the good fortune to work with him. He was a "oner" - an all round good guy and true giant in transfusion medicine, a pioneer who played a key role in one of our greatest success stories, the prevention of Rh hemolytic disease of the newborn

Usurpation of identity
Zimmermann R, J, Weisbach V, Eckstein R. ABO discrepancy by usurpation of identity Transfusion 2005 Mar; 45(3):454.
Over the years I have seen 2 cases of usurpation of identity, both while working in the centralized transfusion service of the Canadian Red Cross (now Canadian Blood Services) in Winnipeg, Canada. For U.S. readers, Winnipeg's blood system is similar to that of the Puget Sound Blood Center - a combined blood center/transfusion service, with a centralized crossmatch facility serving the city of Winnipeg and smaller sites across the province.
In one case, an unconscious young man was admitted to the emergency department of a local hospital following a car accident. A blood group done on his current sample was different than the historical record. It turned out that he was carrying his friend's identity card in order to meet the legal age of drinking alcohol.
The second case involved a young women who was having a therapeutic abortion. Similarly, her current blood group differed from her historical record. Once questioned, she admitted to passing herself off as her friend, to the point of deceiving a physician. The reason for the deception was social, not financial, since Canada, like most of the developed world, has universal healthcare.
In both instances, the discrepancy would not have been caught were it not for the record. No harm would have come to the perpetrators since they would have received blood of the correct groups, based on their current typing results. In the future, however, such deception might have consequences for their friends, should they ever require blood products based on historical records alone.
In the USA where many people lack health insurance, such deception may be more widespread.
Regardless, although records play a major role in preventing misidentification, both cases illustrate the importance of not relying on records.
If you have first-hand knowledge of similar cases of identity theft in patients requiring transfusion, please e-mail me. Many thanks!

"Who's who" in Transfusion Medicine- Mike Murphy
A current hot topic is use of mistake-proofing tools such as electronic blood transfusion systems using bar codes or RFID. One of the recent TraQ case studies includes a section on mistake-proofing technology:
One of the experts actively involved in new technology is Dr. Mike Murphy from John Radcliffe Hospital and the University of Oxford:

Access change at BMJ
Original research articles remain free but the full text of other articles (e.g., editorials and reviews) are free only for the first week after publication and then under access controls for the next 51 weeks, after which all content will once again be free.
Since editorials and reviews are important sources of topic overviews, I recommend that users subscribe to the weekly alerts for the BMJ table of contents.
Then be sure to access the editorials and reviews within one week. <;-)
- Tip: "Save as" (under FILE menu): Save reviews and editorials to your desktop as web pages (.htm or .html files) for reading later at your leisure.

Tsunami victims & Rh negative rbc
Rh negative blood needed in Thailand to treat western tsunami victims
The frequency of the Rh(D) antigen in Caucasians in N.A and Europe is ~85% but has a frequency in parts of Asia approroaching 100%. It makes sense that western tourists requiring transfusion need other westerners to donate.

Ongoing controversy at South African National Blood Service
After the policy was exposed, the South African National Blood Service (SANBS) said that its risk management program was flawed because it relied heavily on race as a risk factor and that the risk model would be revised. SANBS also apologized to President Mbeki whose blood was discarded.
Subsequently, the organization was accused of sexual discrimination because it classifies donors who admitted to man-to-man sex as high risk, despite the statistics that in SA heterosexual women aged 18 to 24 are at high risk for HIV infections.
The latest issue is that SANBS has had to defend its policy of selling donated blood, explaining that they do not charge for blood per se, but rather for services rendered in the procurement, collection, testing, processing,and issuing of blood.
Despite the controversies, it is likely that SANBS will be chosen as South Africa's new national blood transfusion service.

Limitations of Google Scholar
Limitations of Google Scholar (still in beta testing) are beginning to appear. For example:
- Google Scholar documentation (Search Engine Watch)
- Google Scholarly (Free Pint)
Main messages are that documentation is lacking on what's in the database (not always "scholarly") and that students may bypass established databases containing peer reviewed papers.

Google Scholar
I particularly like the "cited by" feature, which provides links to other papers that have cited the original (at least the ones in Scholar's database). This type of citation analysis is an innovative variation of PubMed's invaluable "related articles" feature.
Sample Searches. Got to http://scholar.google.com and enter:
Ex. 1. Heddle transfusion
Ex. 2. predictive value transfusion
Ex. 3. root cause analysis transfusion

The UK Dept. of Health has now called for Public consultation on The Blood Safety and Quality Regulations 2005
Although the EU Directive does not specifically require accreditation, licensing or inspection of hospital blood banks, it does make them subject to several articles, including those concerning
- PersonnelQuality Management
- Quality system and DocumentationHaemovigilance - Traceability & Notification of serious adverse events and reactions
- Quality and Safety of Blood and Blood Components - Storage, transport and distribution conditions
- Data protection and confidentiality
In Canada, we do not yet know which Z902-04 clauses will become government regulations but it will be interesting see how closely they mirror the EU Directive approach. For more information, see TraQ's backgrounder on the EU Directive

International Woman in Transfusion Award
It's not surprising that a year would come when women headed several major TM organizations as women are incredibly active in transfusion medicine. I encourage everyone to consider nominating one of your colleages for this new award.
As to the 3 presidents - I'm tempted to say "3 amigos"....
- see brief profiles on
- AABB President Kathleen Sazama, MD, JD (Source: Society for the Advancement of Blood Management )
- BBTS President Judith Chapman, FIBMS, MBA
(Source: UK Blood Stocks Management Scheme) - ISBT President Francine Décary, MD, PhD, MBA(Source: University of Sherbrooke)

Transfusion medicine forums and mailing lists
On the plus side, it's great to have multiple sources of information and places to ask questions. On the downside, searching in multiple places takes time and any information found must be carefully evaluated for validity and relevance.
A rule of thumb is that moderated lists have higher quality information, which would place the CBBS e-network Forum moderated by Ira Shulman, MD at the top of the pecking order in the TraQ list. Indeed, the entire CBBS website maintained by webmasters J. Lawrence Naiman, MD and Eileen A. Selogie, MT (ASCP) SBB) is a class act!

Québec eliminates upper age limit for donors
There are several safety criteria involving approval from the donor's physician but it seems that so long as "the bod is warm" and you are in good health, you can now be a life-long blood donor.
A few statisics to ponder:
- According to Statistics Canada, in 2004 ~5.6 million (17.7%) of Canada's total population of 32 million are over 60.
- In Canada only 3.7 % of eligible people are blood donors. By comparison, 6% of Britains donate blood; in the USA, Ireland and Japan, the figure is ~5%, while in Taiwan, it's 7.5 % - nearly double the total in Canada.
With demographics like these we definitely need our oldsters - tried and true donors with multiple donations to their credit, to continue to give, and give, and give.....
Resources:
- CBS press release (June 2004): Less than four out of every 100 eligible Canadians donate blood each year
- Statistics Canada: Population by age & sex

Readers beware
From what was reported in the articles, Dr. Lorna Wilkinson discussed the UK SHOT scheme. Chris Hogan (an Australian hematologist) and Neil Boyce (of the Australian Red Cross Blood Service) spoke on efforts in Australia to improve processes and develop a reporting scheme such as SHOT. All speakers noted the rare but potentially fatal consequences of identification errors.
From my perspective, The Age news report presents a more balanced view than the Sydney Morning Herald report does. The latter's headline (Hospitals ignoring blood label rules) sets the tone for the article and is misleading.
