As I read this thread several points come to mind as a blood banker for 15+ years now in IT. Ideally as a blood banker would I want this info? Yes but, only for those patients who had a positive result. Importing all those negatives means I have to search through more data to ensure that I'm really looking at the patient I think I am. How many of these converted patients have passed on, or passed through your area and will just be clutter? Pragmatically from the IT standpoint several thoughts come to mind. Who's going to pay for this conversion? Who from the now defunct organization will work with the 3rd party to do the conversion? Does your current hospital want to pay for this conversion? I know the almightily dollar shouldn't rule the world but I bet your hospital isn't willing to pay the 50K+ it's going to cost to get the info. What are you going to use as identifiers for this conversion. Generally it's Name, DOB, Sex, SSN needed for computer matching of the admission record to a blood bank record. (MRN omitted as we are obviously not comparing apples to apples) I can understand the reluctance of the defunct institution of not wanting the SSN of all of their old patients with blood bank records being put out there. Finally who becomes responsible for all the records that are not an exact match? John Doe vs John R Doe same DOB, Sex and SSN, do you throw those out? What on the surface seems like a simple and reasonable request is actually as all on this thread have pointed out, quite complex.
