Definitions for the PhdDeviceAlert resource profile
Guidance on how to interpret the contents of this table can be foundhere
| 0. DeviceAlert | |
| Definition | Describes a noteworthy condition or occurrence determined to exist by a device. |
| Short | Documentation of an alert (a.k.a. alarm) generated by a device indicating a noteworthy condition |
| Comments | The DeviceAlert resource is derived from the ISO/IEEE 11073-10201 Domain Information Model standard, but is more widely applicable. |
| Control | 0..* |
| Is Modifier | false |
| Must Support | false |
| Summary | false |
| Invariants | dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (contained.where((('#'+id.trace('id') in %resource.descendants().select(reference | as(uri))) or descendants().where(reference='#' | as(uri)='#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (text.`div`.exists()) |
| 2. DeviceAlert.implicitRules | |
| Definition | 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. For DomainResources, if more than one implicitRules policy applies, additional policies may be conveyed using the additionalImplicitRules extension. |
| Short | A set of rules under which this content was created |
| Comments | 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 its narrative along with other profiles, value sets, etc. |
| Control | 0..1 |
| Type | uri |
| Is Modifier | true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies its meaning or interpretation |

| Summary | true |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 4. DeviceAlert.contained | |
| Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning. |
| Short | Contained, inline Resources |
| Comments | This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels. Contained resources may be a resource type defined in the FHIR specification, or an additional resource. |

| 6. DeviceAlert.modifierExtension | |
| Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |
| Short | Extensions that cannot be ignored |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |

| Definition | A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. |
| Short | Text summary of the resource, for human interpretation |
| Comments | Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. |

| Short | High level categorization of device alert |
| Comments | Categorization might be done automatically (inferred by code) or manually by user assertion. The absence of a category may limit the ability to determine when the element should be handled, so strong consideration should be given to how systems will be able to determine category values for legacy data and how data that cannot be categorized will be handled. As well, some categories might not be mutually exclusive, so systems should prepare for multiple declared categories - even within a single category 'axis'. |

To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |

| Definition | May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |

| Type | Extension |
| Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the element that contains them |
| Summary | true |
| Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. |
