The DICOM AEs that claim conformance to this SOP Class as an SCU shall invoke the N-ACTION request. The DICOM AEs that claim conformance to this SOP Class as an SCP shall support the N-ACTION request.
This operation allows an SCU to submit a Medication Administration Record log item or entry, providing information about a specific real-world act of Substance Administration that is the purview of the SCU. This operation shall be invoked through the DIMSE N-ACTION Service.
The Action Information attributes are defined by the Substance Administration Log Module specified in PS3.3. The DICOM AEs that claim conformance to this SOP Class as an SCU and/or an SCP shall support the Action Type and Action Information Attributes in the N-ACTION-RQ as specified in Table P.3-2.

The SCU shall request logging of substance administration events for a specified Patient using the N-ACTION request primitive.
The SCU shall receive N-ACTION responses. The actions taken upon a response status of Failure, or upon non-response of the SCP, are implementation dependent.
The SCP shall receive, via the N-ACTION request primitive, requests for logging of substance administration events. The SCP shall incorporate those event records into a Medication Administration Record or similar log for the specified Patient.
Note: The patient’s identify may be conveyed explicitly by Patient ID (0010,0020), or implicitly by Admission (i.e., Visit) ID (0038,0010). An institution may typically chose one or the other to use as the primary patient identifier at the point of care, e.g., printed on a bar coded wristband, the use of which may facilitate data entry for the log entry. However, in the “Model of the Real World for the Purpose of Modality-IS Interface” (see PS 3.3), the Visit is subsidiary to the Patient; hence the Admission ID (0038,0010) may only be unique within the context of the patient, not within the context of the institution. The use of the Admission ID (0038,0010) Attribute to identify the Patient is only effective if the Admission ID (0038,0010) is unique within the context of the institution.
The SCP shall support inclusion into the Medication Administration Record or similar log of values of all Type 1 and Type 2 Attributes for which the SCU has provided values. The SCP may convert these attributes into a form appropriate for the destination log.
Note: The SCP may convert coded data to free text in the log, with loss of the specific code values, if the log does not support such coded data.
The SCP shall return, via the N-ACTION response primitive, the N-ACTION Response Status Code applicable to the associated action request.
The Service Class specific status values defined for the N-ACTION Service are specified in Table P.3-3. See PS 3.7 for additional general response status codes.
Table P.3-3RESPONSE STATUS
|Service Status||Response Status Code||Further Meaning|
|Failure||C10E||Operator not authorized to add entry to Medication Administration Record|
|C110||Patient cannot be identified from Patient ID (0010,0020)or Admission ID (0038,0010)|
|C111||Update of Medication Administration Record failed|
