There are two things here - keeping tabs on all recordings made while a person was/is pregnant - keeping clinical track of the fact that the person is pregnant.
My proposal is to have an archetype for pregnancy - it will obviously vary a little (specialisation) from place to place but there are some consistent data that can be collected for all.
The traditional manner of keeping key information about a pregnancy is here and there - throughout the EHR. The advantage of using 'persistence' for this data is that it is clear that a person has been pregnant x times (how many pregnany EVALUATIONs are in the EHR) are they pregnant now?, are they breast feeding - only one place to look!
This will not have all the information - not the exams, symptoms....fetal heart measurements - just the persistant data - EDD, LMP, number of offspring, birthweight(s), names, date of delivery, means of delivery, place of delivery.
It is different than we are used to - but could look like it is done now through the GUI.
