caBIG® Clinical Information Suite Patient Trial Finder
Patient Trial Finder Review Use Cases & Descriptions : • Identify Scope of Analysis • Discuss Use Case Relationships • Confirm Descriptions and Conditions • Primary Event Flow • Requirements • Review & Confirm
This diagram shows all the use cases and actors touched on in our discussions and research. The actors here represent roles. The Information Source Role (system role) represents the collection of registered trials including those which a site has approval to offer. The boundary (PatientTrialFinder) shows the scope of our topic by differentiating those use cases for which we believe our reference implementation should be supporting.
Diagram - Select Clinical Trial • 1.07.04 Manual search, often for a single known trial. • 1.07.03 Exhaustive search, retrieving all trials that fit the sum of currently known medical data for the patient. • 1.07.01 The act of comparing a particular trial to a particular set of patient data (ranking) • 1.07.02 Organizing the set of all possible trials by various criteria (type, treatment, distance, etc) Note: Numbering is just for identification and not meant to represent sequence.

1. Retrieve Single Trial Detail • The title and/or unique identifier of the trial is known • Unique keyword is known • The details of a specific trial are sought • Unique identifiers are attributed to trials in several schemes. • Clinical Trials.gov (e.g. NCT00032890) • National Cancer Institute ( e.g. NCI-02-C-0052, discontinued as registry in 2010) • Sponsor-assigned unique ID (e.g. Merck-023) • US NIH Grant/Contract Award Number (e.g. R01DA013131) • European Union Drug Regulatory Authorities Clinical Trial System • Universal Trial Number (WHO International Clinical Trials Registry Platform) The aim of the UTN is to facilitate the unambiguous identification of clinical trials.

3. Compare Trial and Patient Criteria • To match any trial with the given medical data of a patient, a consideration of the trial criteria has to be assessed for similarity to the patient medical profile • Pre-conditions: • A description of the trial inclusion/exclusion criteria is available • A description of the trial protocol is available • A medical history of the patient is available • Any current treatment plan for the patient is available • Post-conditions: • The trial is recommended or not. • If recommended, some rank ordering is assigned. «actor» ACT10.01: Information Source PTF-UC01.07.01 Compare 3.
