The data in the Resource covers the "who" information about the patient: its attributes are focused on the demographic information necessary to support the administrative, financial and logistic procedures. A Patient record is generally created and maintained by each organization providing care for a patient. A patient or animal receiving care at multiple organizations may therefore have its information present in multiple Patient Resources.

Managing Patient registration is a well known difficult problem. Around 2% of registrations are in error, mostly duplicate records. Sometimes the duplicate record is caught fairly quickly and retired before much data is accumulated. In other cases, substantial amounts of data may accumulate. By using a link of type 'replace', the record containing such a link is marked as a duplicate and the link points forward to a record that should be used instead. Note that the record pointed to may in its turn have been identified as created in error and forward to yet another Patient resource.

In a distributed architecture, multiple systems keep separate patient records concerning the same patient. These records are not considered duplicates, but contain a distributed, potentially overlapping view of the patient's data. Each such record may have its own focus or maintaining organization and there need not be a sense of one record being more complete or more authorative than another. In such cases, links of type 'see also' can be used to point to other patient records. It is not a requirement that such links are bilateral.

Patient
vs.
Person
vs.
Patient.Link
8.1.5
Patient vs. Person vs. Patient.Link The
Person
resource
on
the
surface
appears
to
be
very
similar
to
the
Patient
resource,
and
the
usage
for
it
is
very
similar
to
using
the
Patient.Link
capability.
The
intention
of
the
Person
resource
is
to
be
able
to
link
instances
of
resources
together
that
are
believed
to
be
the
same
individual.
This
includes
across
resource
types,
such
as
RelatedPerson,
Practitioner,
Patient
and
even
other
Person
resources.
The
Patient
Link
however
is
only
intended
to
be
used
for
Patient
resources.
The
primary
use
case
for
the
Person
resource
is
to
be
able
to
support
person
registries
that
do
not
necessarily
have
a
healthcare
context,
and
are
able
to
identify
and
quantify
confidence
levels
that
this
is
the
same
person.
This
could
include
consumer
portals
where
the
maintainer
of
the
person
information
is
the
actual
person
themselves.
A
system
could
use
the
Person
entry
to
cross
check
changes
to
information
applied
to
one
part
of
a
record
to
values
in
another
system;
e.g.,
when
moving,
a
consumer
updates
his
contact
numbers
and
address
in
his
person
record,
and
then
a
Patient
Administration
system
is
able
to
see
that
this
data
is
changed
and
prompt
the
organization
to
follow
up
with
the
patient
that
was
linked
to
the
person
record
if
they
want
their
details
updated,
or
if
they
no
longer
need
services
and
they
should
be
cancelled,
as
they've
moved
from
the
area.
The Person resource on the surface appears to be very similar to the Patient resource, and the usage for it is very similar to using the Patient.Link capability.
The intention of the Person resource is to be able to link instances of resources together that are believed to be the same individual. This includes across resource types, such as RelatedPerson, Practitioner, Patient and even other Person resources.
The Patient Link however is only intended to be used for Patient resources.
The primary use case for the Person resource is to be able to support person registries that do not necessarily have a healthcare context, and are able to identify and quantify confidence levels that this is the same person.
This could include consumer portals where the maintainer of the person information is the actual person themselves.
A system could use the Person entry to cross check changes to information applied to one part of a record to values in another system; e.g., when moving, a consumer updates his contact numbers and address in his person record, and then a Patient Administration system is able to see that this data is changed and prompt the organization to follow up with the patient that was linked to the person record if they want their details updated, or if they no longer need services and they should be cancelled, as they've moved from the area.
5.1.6
Patient.contact
vs.
RelatedPerson
8.1.6
Patient.contact vs. RelatedPerson The
contact
element
on
the
Patient
Resource
should
be
used
for
storing
people
to
contact
information.
Where
a
system
has
a
separate
record
for
other
people
for
purposes
other
than
just
the
contact
details,
the
RelatedPerson
resource
should
be
used.
This
includes
cases
where
these
related
people
are
actually
contributing
to
the
record,
and
need
to
be
referenced
individually
(e.g.
CarePlan.Participant,
Encounter,
DocumentReference,
Appointment)
where
the
Patient.Contact
component
cannot
be
used.
It
is
not
expected
that
these
records
will
be
used
for
recording
the
primary
care
provider;
this
information
should
be
stored
in
the
Patient.careProvider
field.
The contact element on the Patient Resource should be used for storing people to contact information. Where a system has a separate record for other people for purposes other than just the contact details, the RelatedPerson resource should be used.
This includes cases where these related people are actually contributing to the record, and need to be referenced individually (e.g. CarePlan.Participant, Encounter, DocumentReference, Appointment) where the Patient.Contact component cannot be used.
It is not expected that these records will be used for recording the primary care provider; this information should be stored in the Patient.generalPractitioner field.

Feedback
here
There are several ways to represent the relationship between a mother and a child. This is due to the when it is recorded and the purpose for which it is recorded:
To express the family relationship and legal responsibility thereof for administrative purposes: use the Patient/RelatedPerson structure.
This structure is consistent over time.
To relate the encounter of a mother and her baby for a maternity encounter, for administrative and billing purposes: use the
encounter.partof
property
To collect information about the patient's relatives that might be relevant to the patient's medical condition: use the
FamilyMemberHistory
resource
During a maternity encounter, the Patient and Encounter resources for the mother will be present. After the child is born, new Patient, Encounter and RelatedPerson (for the mother) records will be created. The Child's encounter should reference the Mother's encounter using the partOf property. The Patient/RelatedPerson structure should also be created for ongoing usage, as shown in this example:
This specification does not specify merge functionality: if multiple patient records are found to be duplicates, they can be linked together, as described above. These links merely express the relationship between records, and in the case of a replacement link, indicate a "master" record. This specification does not mandate that FHIR servers migrate information between such records on finding such a link. Note:
Health information administrators may call the process "merging", but it is often implemented as "linking" at the record level
Servers are allowed to implement merging/record migration even though it is not mandated.
DSTU Note:
We are seeking input from the implementer community on what effect linking/merging/unlinking should have on other functionality such as the GET operation (where the result is the old version of the Patient), searching, reverse includes, etc.; e.g., should observation resources from all linked/merged patients be returned when querying for one of them? How should an unlink behavior be done? (Assuming that no data was "re-allocated" as part of merge) These suggested updated behaviors could be the subject of a future connectathon.

One optional parameter to the MPI match operation is "userid", which is used to pass the user details from a trusted client to the MPI. This may be used by the MPI to restrict the possible matches that are returned, based on the user's rights. For example, a staff member covered by policies, etc., may well get a different result than a patient trying to find their own record. Note that this parameter is used where the user would not be expected to log in to the MPI directly; whether this is appropriate or not is a deployment choice.
