With HIPAA laws and lawyers being what they are nowadays, patient privacy is now being guarded more closely than our nuclear secrets at Los Alamos.
If that tech had said anything, that mother could have her at the other end of a lawsuit claiming damages for invasion of privacy and emotional distress for spoiling the surprise she always dreamed of having at the end of childbirth and the husband would also be suing the tech for loss of companionship with his wife.
I wish that were the case. In fact, the purpose of HIPAA is to inform the patient of all the conditions under which his medical records will be made public.
