There's not much I can add to what has already been stated ... a learning experience, talk about it so you can be better prepared next time, etc. Except ... 1. Your supervisor dropped the ball here. As 'Quality Guy' quoted CLIA (and it should be a 'rule' regardless of who requires it), your supervisor should have a 'call me anytime and if you can't get me, call ____' with the phone numbers perpetually posted at every BB phone.As far as the policy about 'the patient has not been transfused so you do not need to repeat the workup' - yes, it may be a rational thing to do, but unless this exception is written in your policies, you are not free to skip the testing. That exception should be written in your procedures and you should have been informed of it during your training. Sounds like you were not trained to deal with 'unusual crisis' cases. Were you trained in what antibodies are truly 'clinically signficant'? Were you trained what to do if you have a crisis patient who has 'clinically significant antibodies'? ... or other issues like IgA Deficiency, Sickle Cell Protocol, etc.?2. "Remember exanguination is a lot harder to treat than a transfusion reaction." Keep in mind that it's up to the attending MD to decide if the patient can wait until all the required testing is done or not ... it's not the Blood Bank's responsibility. All the demands, threatening statements, and loud voices are not going to change that fact. The responsibilities of the BB Tech are: to inform the requesting MD of any additional risks (e.g. clinically signficant antibody, IgA Deficiency)to convey to the requesting MD the TIMING for filling the order (very important, they will change care plans based on what is said) and not burdening them with the details about 'how'.to do whatever tasks are necessary to get the safest blood out the door in a timely manner in accordance to whatever can be done in the given period of time, e.g. Group O RBCs vs Type Compatible RBCs vs crossmatched RBCs.to focus on those tasks, not worrying about what's happening in the ED or who's screaming on the phone or what MAY happen 'if'.Yes, it's all these things that help techs get through these tougher situations. You lucked out with this crisis, but as you are feeling, you need more support and more information ... get those things before this happens again.
