        <p> A Master Patient Index (
          <a href="http://en.wikipedia.org/wiki/Enterprise_master_patient_index">MPI</a>  ) is a service used to manage patient identification in a context where multiple patient
           databases exist. Healthcare applications and middleware use the MPI to match patients
           between the databases, and as new patient details are encountered. MPIs are highly specialized
           applications, often tailored extensively to the institution's particular mix of patients.
           MPIs can also be run on a regional and national basis.
        </p> 

        <p> To ask an MPI to match a patient, clients use the &quot;$match&quot; operation, which
           accepts a patient resource which may be only partially complete. The data provided is
           interpreted as an MPI input and passed processed by an algorithm of some kind that uses
           the data to determine the most appropriate matches in the patient set.  Note that different
           MPI matching algorithms have different required inputs. The generic $match operation does
           not specify any particular algorithm, nor a minimum set of information that must be provided
           when asking for an MPI match operation to be performed, but may implementations will have
           a set of minimum information, which may be declared in their definition of the $match
           operation by specifying a profile on the resource parameter, indicating which properties
           are required in the search.  The patient resource coming into the operation does not have
           to be complete, nor does it need to pass validation (i.e. Mandatory fields don't need
           to be populated), but it does have to be a valid instance. This is due to the resource
           being used for reference data to match from, and not being stored.</p>
