EDD Calculation

 

This subsection appears in the Ob Episode tab of the patient chart

 

 

What is an OB episode?

athenaOne refers to the clinical and billing time period of a patient's pregnancy as an OB episode; the OB episode is a mechanism to track OB enrollments and information about clinical outcomes. Enrollment, EDD, and delivery reports organize information captured in the OB episode. Once saved, OB episode information is available for reporting. You can report on three main items: enrollment, EDD, and deliveries.

 

OB episode and athenaClinicals

In the patient chart, click the Menu icon and select Start OB episode. To view and edit an existing OB episode, click Pregnancy Problems in the Problems tab of the patient chart.

Note: To help you care for your transgender and nonbinary patients, the Start OB episode option is available when the Assigned sex at birth field is set to any of these values: Female, Choose not to disclose, or Unknown.

 

After you create an OB episode, the patient banner displays the following information about the episode: gravidity and parity, duration of pregnancy expressed as "weeks.days," estimated date of delivery (EDD), and blood type.
Note: If your practice has different chart sharing groups, the OB episode information appears only when viewing the patient chart with the open OB episode.

 

The top section of the OB Episode tab is used to track initial information about the pregnancy and to estimate the patient's EDD. After the initial data is saved, the Prenatal Flowsheet section also appears in the OB Episode tab.

 

After this information is completed and the OB episode is closed, the Past Pregnancies section and Obstetric History section of the patient's chart are automatically updated according to the OB episode outcome.

 

Note: When a provider orders a RhoGam injection (using any order type that is considered RhoGam), an entry appears on the Results section of the patient's OB Episode tab indicating the date of the injection. This information also prints on the OB Episode form.
