Thanks Ben and Burke,

One thing Mark brings up is the notion that we want to be able to model Types of Providers, as well as the types of services that they can provide. Is there any notion of this built into the 1.9 Provider model or the future road map for Provider? Is the intention that ProviderAttribute is meant to provide sufficient flexibility to encapsulate either Provider Types or Provider Services (or Provider anything else) as needed? If so, I get that, but want to confirm that this is the direction intended. I could see a case for modeling one or both of these explicitly, as it would seem that ProviderType is something we are going to frequently want to support (eg. show a list of all Surgeons on form X, or all Community Health Workers on page Y).

The encounter represents a clinical transaction in our model, so as Ben suggests, a provider providing clinical services for a patient would fall into an encounter, which (eventually) could generate any number of observations, orders, notes, or form data.

For denoting ongoing relationships between persons (e.g., providers & patients), we would use the relationship model.

To connect multiple encounters over time, you could use the visit model (created to group encounters, but usually representing a series of contiguous encounters) or the yet-to-be-implemented episodes of care, which are designed to connect encounters related to a treatment program across multiple, possibly non-contiguous, visits (e.g., pregnancy).

FWIW, I believe we added (or planned to add) date ranges to relationships; however, if you want to track "service" (possibly for billing purposes), then I would suggest using visits, since that's where an account number would go.

Note that these aren't mutually exclusive. For example, you could create relationships to track relationships between accompagnateurs and their patients and still record encounters +/- visits for clinical transactions between the provider and their patient.

    Ben,

    Hmm… that may be the way to do it generically, but I don’t know if
    it works for us since we need to model this over time.

    Would you be able to store these as the encounterrole for that CHW
    for each encounter?

    I’ve been looking at the new Provider model in 1.9, and I was
    wondering if thought has been put into modeling provider types
    (Cardiologist, PCP) and specific provider services, and how to
record that a provider provided a specific service to a patient. Do we have a vision as to how we may want to model this going forward?

    The reason I’m asking is that I’m currently working on determining
    how PIH wants to model Community Health Workers within our system,
    and I’m considering how they may fall into a more generic provider
    structure. We want to be able to handle various types of CHWs
    (Accompagnateurs, Pallative care workers, Community Health Nurses)
    that provide various services (HIV accompaniment, end-of-life
    care, etc) that we’d like to be able to model, and then we’d like
    to be able to track what services are being provided to what
    patients.  Additionally, we need to track the dates over which a
    CHW provided such a service, ie:

    “Accompagnateur A provided HIV accompaniment to Patient B from
    1/2/2010 to 3/4/2011”

    At first, it seems like Relationships would be the way to model
    this kind of interaction, since a relationship defines a
    relationship between two people, and (as of 1.9) can have a start
    date and an end date.  However, it doesn’t quite seem to be the
    right way to do this, primarily because a relationship is a
    Person-to-Person relationship, when what we are modeling is a
    Provider-to-Patient relationship.  It seems like this is an
    archetypical relationship in an EMR that it may make sense to
    model in a different manner than general relationships.

    Take care,

    Mark
