September 18, 2007HL7 V3 Lab-Based Adverse Event Assessment Message Specification5 of 22 Storyboard Overview Laboratory test results can indicate a patient has experienced/is experiencing an adverse event (AE). For clinical trials mandating use of a grading criteria for assessing laboratory result-based AEs, laboratory test results may be transmitted to an automated AE assessment service. The AE assessment service evaluates the laboratory results subject to quantitative AE assessment, based on the specified grading criteria, such as the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events v3.0 (CTCAE). An initial / first-level assessment is performed to determine the presence and severity of an AE(s). Upon completion, the laboratory test results and associated AE assessment outcomes are transmitted to a clinical information system within the clinical research environment. Subsequent investigation into the patients condition must be conducted within the clinical research environment in order to determine, in part, the AE reporting requirements.

September 18, 2007HL7 V3 Lab-Based Adverse Event Assessment Message Specification6 of 22 Storyboard CT Laboratory Result-based Adverse Event Assessment (PORT_SN03000x) Narrative A laboratory facility has performed one or more tests on a patient specimen and the results of the testing are available electronically for review and further evaluation within the clinical research environment. A request is sent to an automated AE assessment service to evaluate the laboratory test results. Each test result that is subject to quantitative AE assessment is evaluated for the presence and severity of an adverse event, and the test result is appended with this AE assessment outcome data. The AE assessment service sends a response message containing the original and appended information.

September 18, 2007HL7 V3 Lab-Based Adverse Event Assessment Message Specification8 of 22 Interaction Design Elements & Descriptions: Application Roles ClinicalTrial Observation Order Global Placer (PORT_AR03000x) An application that is capable of notifying another application about a significant clinical trial observation event and expects the receiver to take action. Adverse Event Assessment Observation Fulfiller (PORT_AR03000y) An application that is capable of receiving an adverse event (AE) assessment request from a Placer application. The Adverse Event Assessment Observation Fulfiller is responsible for evaluating clinical trial laboratory results and deriving AE assessment outcome data. The fulfiller is also responsible for initiating communication of this data to the Clinical Observation Event Global Tracker. ClinicalTrial Observation Event Global Tracker (PORT_AR010001UV01) The application role includes the behaviors needed to receive and appropriately manage notifications from another system about any change of a Clinical Trial Observation Event. This includes receiving information about status changes of that event and receipt of observation event information once that is available.

September 18, 2007HL7 V3 Lab-Based Adverse Event Assessment Message Specification9 of 22 Interaction Design Elements & Descriptions: Trigger Event Agreed Transmission Criterion Attained – CT (PORT_TE010001UV01) An external event has occurred which marks a condition under which the sender and receiver have agreed that data is to be exchanged. Such events are often defined time points (e.g. end of business day/week/month). In a clinical trial, these may be significant milestones (e.g. subject enrolled; subject completes phase; all subjects complete phase; end of study). CT Laboratory Results Adverse Event Assessment Request (PORT_IN03000x) This interaction supports communication of clinical laboratory results to an AE assessment service. It is expected that the receiving application will initiate the CT Laboratory Results AE Assessment Response interaction (PORT_IN03000y) containing the original clinical laboratory results, in addition to the outcome of the initial / first-level quantitative adverse event assessment. CT Laboratory Results Adverse Event Assessment Response (PORT_IN03000y) This interaction supports communication of clinical laboratory results with the outcome of the initial / first-level quantitative adverse event assessment to a clinical information system within the clinical research environment / study site.

September 18, 2007HL7 V3 Lab-Based Adverse Event Assessment Message Specification18 of 22 CMET RMIM Class Definitions AdverseEventAssessment The process of evaluating a clinical finding to detect the presence and severity of an abnormal condition, and assigning the corresponding adverse event category, term, and grade. AssessmentException This class represents one of two possible observation outcomes of an AdverseEventAssessment. It is a message provided to indicate that an adverse event assessment could not be executed or completed and to identify the reason for the failure. AdverseEventGrade This class represents one of two possible observation outcomes of the AdverseEventAssessment. It is the severity of an adverse event based on a specified assessment scale. GradeAnnotation Additional information provided about a grade that must be considered to determine the final grade.

New value sets for existing domains Adverse Event Assessment Method: provides additional information about the means used to arrive at the assessment result. Adverse Event Assessment Exception: provides the reason an adverse event assessment could not be executed or completed Adverse Event Grade: indicates the level of severity for an adverse event, including the concept of Not Present. Adverse Event Grade Annotation: provides additional information about an adverse event assessment grade, which must be considered before determining the final grade. Focused discussion regarding these vocabulary requirements will be held during the working group meeting. The session is to be determined.
