Note that for both humans and particularly animals, there are other legitimate possibilities than male and female, though the vast majority of systems and contexts only support male and female.  Systems providing decision support or enforcing business rules should ideally do this on the basis of Observations dealing with the specific sex or gender aspect of interest (anatomical, chromosomal, social, etc.)  However, because these observations are infrequently recorded, defaulting to the administrative gender is common practice.  Where such defaulting occurs, rule enforcement should allow for the variation between administrative and biological, chromosomal and other gender aspects.  For example, an alert about a hysterectomy on a male should be handled as a warning or overridable error, not a &quot;hard&quot; error.  See the Patient Gender and Sex section for additional information about communicating patient gender and sex."/>

Multiple GPs may be recorded against the patient for various reasons, such as a student that has his home GP listed along with the GP at university during the school semesters, or a &quot;fly-in/fly-out&quot; worker that has the onsite GP also included with his home GP to remain aware of medical issues.
