This is the base resource type for everything.

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

The base language in which the resource is written.

Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

The business identifier(s) for the addiction condition - This is an optional attribute, used for example to track an addiction throughout its lifecycle, or across vaults.

The patient

Here the type of addiction will be specified (e.g. alcohol, drugs, medication). It SHOULD be expressed in a codified way (Valueset will be delivered by NIHDI).

Here it is possible to further refine the addiction information e.g. when "narcotics" is indicated, this can specify the substance

The date when the addiction is being recorded or updated

The actual period this addiction was true. (e.g. used when a patient used to abuse alcohol) - or the beginning of addiction in case the addiction is still active

The actual period of the addiction or the beginning of addiction in case the addiction is still active

A free text indication of the time period of addiction - e.g. as "teenager", "approx 5 years ago", etc

e.g. number of cigarettes per day

Is this patient following a treatment for this addiction?

Is this patient following a treatment for this addiction? (In technical reality, this will be actually a Procedure instance that refers to the Addiction instance)

Clinical parties or informers that participate in reporting the addiction

Who was responsible for asserting the observed value as "true".

Who was responsible for asserting the observed value as "true". (Reference)

To mark the performer as 'INF' (informer) - in case the addiction is reported by family

Additional information about the addiction - this can be relevant history, any remarks by the patient or professional, etc.
