Schema Info

Schema Items

Timeline

Relevant Tables

• ProtocolMgr_SchemaItems: represents a particular set of items to be collected (collect LabDate and LabResult for Lab Tests)
• ProtocolMgr_Timeline: represents visit
• ProtocolMgr_ItemTimeline: represents a particular set of items on a visit
• ProtocolMgr_PatientItems: a patient's specific particular set of items for a particular date.
• RelatedRecords: used to relate one record to another

Advanced Scheduling

Visits which have advanced scheduling are marked in the visit's ItemIntervalType field to signify the scheduling. A pipe is used to delimit multiple advanced scheduling features.

ProtocolMgr_Timeline

• ItemIntervalType: "Recurring", "Dependent Off Treatment", "Recurring|Dependent Off Treatment"

Recurring Visits

A recurring visit is a visit that will occur at a set frequency for a set time period. For instance, a visit may occur every 4 Weeks for 16 Weeks, creating 4 visits.

Dependent Visits

A dependent visit is one which will not be scheduled until a specified actions happens in the system, such as a patient status changing or upon completion of a visit.

In both scenarios, a Patient Item record will be created, but NOT scheduled when then are initially placed "On Study", since these dates are computed after an event in the system.

ProtocolMgr_PatientItems

• FirstAnticipatedDate: date is calculated after trigger event
• LastAnticipatedDate: date is calculated after trigger event
• ScheduledAnticipatedDate: date is calculated after trigger event

Depending on a previous Visit's item

In this scenario, when a previous is marked as performed, the dependent visits are then scheduled based upon the performed date of the previous visit, such as Week 3's visit is based on completion of a Pre-Study lab test.

A Related Record entry is used to mark a visit's dependency on another visit's item, as well as marking the ItemIntervalType column as Dependent.

RelatedRecord

• DestTableName: "ProtocolMgr_ItemTimeline" - the visit item on which the visit is dependent
• DestPrimaryKey: pri key of visit item
• SrcTableName: "ProtocolMgr_Timeline" - the dependent visit
• SrcPrimaryKey: pri key of the visit
• SrcSystem: "Caisis" - mark that this an internal Caisis relation

ProtocolMgr_Timeline

• ItemIntervalType: "Recurring"

Depending on a Patient's status

In this scenario, when a specified patient's status is entered, these visits will be scheduled based on that new status. i.e., A patient is placed "Off Treatment", and will require a final visit.

No related record is created in this instance. The mapping to signal this visit as dependent on a status is stored in the ItemIntervalType' field.

ProtocolMgr_Timeline

• ItemIntervalType: "Dependent Off Treatment"

PatientProtocolStatus

• PtProtocolStatus: "Off Treatment" - a status of a patient on a protocol

SQL: visit is matched to patient's status

ProtocolMgr_Timeline.ItemIntervalType LIKE '%Dependent ' + PatientProtocolStatus.PtProtocolStatus + '%'

Multiple Advanced Scheduling Options

Both the recurring and dependent scheduling options can be combined for more complex scenarios, such as a patient will be scheduled for 3 weekly follow up visits 1 week after they go "Off Treatment".
