Study Design Questions |
|
Missing Elements in the Study Design Model | Each activity as defined by the SDM may have some associated sub-activities; as an example the Activity of measuring a blood chemistry value could have the associated sub-activities * Subject at site * Blood draw taken from Subject * Date and time of Sample taken * Blood sample labelled with a unique reference id * Blood sample sent to lab * Lab technician records comments on state of sample * Blood sample analysed (multiple subsequent activities lie here) * Result logged to Lab Information System * Result shared or entered into CRF * Result value checked against defined validation rule * Comment entered on clinical significance of lab result * .... Each of these sub-activities could enter in a study workflow system, and be useful for trial scheduling, etc. Representation: The representation of Roles in ODM is not expansive enough for a full workflow. BPMN heavily uses swimlanes for representation of workflows, but there is no way to catch the full gamut of requirements using the current SDM. Roles may apply to Organisms (such as Site Staff), but can also apply to non-Organisms (such as a machine). Indication of a Role of MRI Machine would provide valuable insight for study site selection or protocol planning; as an example say the executable SoA is entered into a workflow system, but the site knows that an important piece of equipment is out of service for scheduled maintenance at some point, then recruitment could be influenced by following the workflow back to the start. |
