Mapping Chronicles Relationships in Clarity Flashcards
Which database was built to easily store and retrieve small amounts of information across many topics at once?
Clarity. This emphasis is also reflected in the structure of the database, where each row in a table represents a different entity.
(Aug. 2021, 4.5)
Which Epic database was designed to easily store and retrieve large amounts of information about one entity at a time?
Chronicles.
For instance, fetching all the data about one patient, or one account, or one provider, or one user, etc.
(Aug. 2021, 4.5)
What are the two main principles for constructing tables in the Clarity database?
- Minimize redundant data
- Maintain consistent granularity
(Aug. 2021, 4.5)
In the EPT master file, what do contacts represent?
Different patient encounters (one row per encounter)

How does Clarity minimize data redundancy while maintaining granularity?
By mapping a single Chronicles master file to multiple Clarity tables.

What are two Chronicles item characteristics that are particularly important for Clarity queries?
- Add Type
- Response Type
(Aug. 2021, 4.6)
What Chronicles item stores the internal identifier?
The .1 item on the record. Also known as the record ID.
The value stored in the .1 is unique across all records in that master file.
(Aug. 2021, 4.7)
What are the two possible identifiers for contacts in Epic?
- Contact Serial Number (CSN)
- Contact Date Real (CDR)
(Aug. 2021, 4.7)
Define Contact Serial Number (CSN)?
A serial number that is unique for all contacts within that master file.
(Aug. 2021, 4.7)
Define Contact Date Real (CDR)?
A date in Epic’s internal format, followed by two decimal places that start at .00 and increment for each additional contact on the same data.
It is the number of days since 12/31/1840 followed by a two digit decimal that identifies multiple contacts on the same date (from practice test)
(Aug. 2021, 4.7)
Does the meaning of contact differ between master files?
Yes.

Can you assume that one master file has the same structure as another?
No.

What two categories do master files generally fall into?
- Static
- Dynamic
(Aug. 2021, 4.8)
Define static master files.
Static master files:
- Typically contain build records (departments, medications, and providers)
- Build records can be created before documenting care for a patient
In general, the meaning of a contact within a static master file is an update.
For example, when Dr. Walt Whitecoat updates his primary department from EHS Clinic to EMC Family Medicine, his SER provider record will store this change on a new contact.
(Aug. 2021, 4.8)
Define dynamic master files.
Records in dynamic master files are generally created as part of a workflow.
For example, when Dr. Whitecoat places an order for a patient, this will create a new record in the ORD master file.
