A pattern to be followed by resources that represent a product used in healthcare, for clinical or operational purposes.

The current state of the product.

Unknown does not represent "other" - one of the defined statuses must apply. Unknown is used when the authoring system is not sure what the current status is.

A category of the product. For example drug class, or device type. A product can have one or several categories. The categories can be from an official / regulatory source, or internal categorization or classification schemes. Categories are useful in search and retrieval of products, or can be used for determining authorizations, e.g. who can order which kinds of products.

The code assigned to the product, for example a catalog number, Device DI, Drug Code or other. Can be an internally assigned or an official product code such as the manufacturer-assigned code. There may be different codes for a product, having different levels of granularity. For example "0123456789" corresponding to "CompuHyper GlobalMed, UltraImplantable 2.25 x 8 mm".

The organisation (manufacturer, representative or legal authorization holder) that is responsible for the device.

Conveys instance-level information about this product item. One or several physical, countable instances or occurrences of the product.

The identifier for the physical instance, typically a serial number.

The identification of the batch or lot of the product.

The time after which the product is no longer expected to be in proper condition, or its use is not advised or not allowed.

Individual the product is associated with, or which has used the product.

Links the product to the Patient context.

[For resources that aren't patient-specific, the set of allowed resources may be extended to include other things. Group should generally be retained unless there's certainty this resource won't be used for veterinary, research or public health settings where Group may be necessary (e.g. this cage of rats/crate of chickens, group of people in a 5 mile radious of the incident, etc.)].
