Angus, I hear what yoou are saying, but believe me, every rule is created out of a need. Believe it or not, there was a surgeon who would prescibe blood products for pt's as volume, not necessarily b/c they were bleeding. This is post open heart. Now of course they would never have the nerve to say "No," to a doctor, but I guess they were documenting it. Also, I have seen blood products ordered on pt's who were DNR, clearly dying, and sometimes, in those situations, I feel it may be inappropriate to give blood, esp if the living will specifically states no blood products. If someone was ever hemorrhaging, the lab was authorized to release 2 units at a time, all we had to do was put the doc on the phone.
But as far as releasing a lab value w/o knowing the diagnosis, there is never a reason for that, since the lab is NEVER going to have to react to the value, other than to recognize it's critical, and to know when to report it, or know when they maybe should run it again. They will not decide how much insulin to give, if PRBC's are needed, or how much coumadin to give. Maybe they do just need an invitation to read the chart. This needs to be reported so that the person can be addressed , and this behavior stopped. When you write up the incident report, double check that there is not a policy that requires you to release this info, and state that on the policy.
