Tuva Input Layer
The Input Layer is like the API for the Tuva data model. Once raw data sources (e.g. claims and medical records) are mapped to the Input Layer code automatically transforms that data into the Tuva data model (i.e. core data model and all the data marts).
The Input Layer is designed to accomodate both claims and clinical data sources.
Claims Input
eligibility
The eligibility table includes information about a patient's health insurance coverage and demographics (note: we use the word patient as a synonym for member). Every claims dataset should include some sort of eligibility data, otherwise it's impossible to calculate member months, which are needed to calculate measures like PMPM. Each record in the table is intended to represent a unique eligibility (i.e. enrollment) span for a patient with a specific health plan.
Primary Key:
- patient_id
- plan
- enrollment_start_date
- enrollment_end_date
