      <text value="An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research participant. The unintended effects may require additional monitoring, treatment, hospitalization, or may result in death. The AdverseEvent resource also extends to potential or avoided events that could have had such effects. There are two major domains where the AdverseEvent resource is expected to be used. One is in clinical care reported adverse events and the other is in reporting adverse events in clinical  research trial management. Adverse events can be reported by healthcare providers, patients, caregivers or by medical products manufacturers. Given the differences between these two concepts, we recommend consulting the domain specific implementation guides when implementing the AdverseEvent Resource. The implementation guides include specific extensions, value sets and constraints."/>

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 its narrative along with other profiles, value sets, etc."/>
