Hi Community!
We are developing a project in which the hospital will initially convert as much of their EHR data into the OMOP format as possible, and then update this data on a weekly basis. For the initial conversion, the Observation_period_start_date could be considered as the date of the first record in the system. The Observation_period_end_date could be the date of the most recent record, unless there is a significant gap in the records; in such cases, we might split the Observation_period data.
1st question: Is this assumption correct?
Since some patients are still active and may visit the hospital again, my questions are:
2nd question: Does the hospital need to send new Observation_period data for these returning patients? If so, what should be the start and end dates?
3rd question: If a patient visits the hospital again in the future, should we create a new Observation_period, or can we update the existing Observation_period by extending the end_date to the most recent visit date?
Thank you so much,
Ravi
