In the US, specifically Ca, is there a regulation that the transfusion service need to solicit (remind) physicians to notify them of suspected problems that could be related to the transfusion? Ex: hep c, sepsis, etc.

When pt is in house transfusion related events close to transfusion should be caught by our transfusion reaction policy (acute). But events where there is delay in transfusion associated events pt is most likely discharged and we are not getting feedback. Not one case in 2011.

So my question: are we responsible by regulation to request feedback and if so how often and by what method? If not required: what is standard practice?

New York State has regulations about "health care providers" reporting infectious diseases. I believe that these parrallel CDC regultaions about the same.
