Description

Date of the beginning of the enrollment period. If the exact date is unknown, use the first day of the month. For implementation of the CDM, a long span of longitudinal data is desirable. However, an enrollment record is intended to represent the dates for which there is complete capture of all medically-attended events, so the data partner’s knowledge of the validity and usability of the data should inform their choice of enrollment start date, especially for historical data more than a decade old. If ENR_BASIS is encounter- based (“E”), the enrollment start date should not be earlier than the earliest encounter date in the datamart for that patient. If ENR_BASIS is based on insurance coverage (“I”), then the enrollment start date may occur before the earliest encounter date in the datamart for that patient.

Description

Chart abstraction flag is intended to answer the question, "Are you able to request (or review) charts for this person?" This flag does not address chart availability. Note: This field is most relevant for health insurers that can request charts from affiliated providers. This field allows exclusion of patients from studies that require chart review to validate exposures and/or outcomes. It identifies patients for whom charts are never available and for whom the chart can never be requested. Mark as "Yes" if there are no contractual or other restrictions between you and the individual (or sponsor) that would prohibit you from requesting any chart for this patient.

Description

ENR_BASIS is a property of the time period defined. A patient can have multiple entries in the table. Details of categorical definitions: Medical insurance coverage: The start and stop dates are based upon enrollment where the health plan has any responsibility for covering medical care for the member during this enrollment period (i.e., if you expect to observe medical care provided to this member during the enrollment period). Outpatient prescription drug coverage: The start and stop dates are based on enrollment where the health plan has any responsibility for covering outpatient prescription drugs for the member during this enrollment period (i.e., if you expect to observe outpatient pharmacy dispensings for this member during this enrollment period). (New value set item added in v3.1.) Geography: An assertion of complete data capture between the start and end dates based upon geographic characteristics, such as regional isolation. Algorithmic: An assertion of complete data capture between the start and end dates, based on a locally developed or applied algorithm, often using multiple criteria. Encounter-based: The start and stop dates are populated from the earliest-observed encounter and latest-observed encounter. Field definition and value sets modified in v3.1 to include drug coverage.
