Critical dataWhich variables carry the study
Every investigation is different, but the categories are stable. Identifying them is the first step, and it happens before the database is configured.
Participant safety
Serious adverse events, adverse device effects, device deficiencies affecting safety, deaths, hospitalizations and unanticipated adverse device effects. Errors here affect patient protection and regulatory reporting directly.
Primary endpoints
Performance endpoints, clinical effectiveness outcomes, diagnostic accuracy, imaging assessments and functional scores. These variables carry the study conclusion.
Eligibility criteria
Inclusion and exclusion criteria, informed consent and baseline assessments. Incorrect eligibility data compromises study validity, and early review reduces protocol deviations.
Device accountability
Serial numbers, batch or lot numbers, implantation and explantation dates, device returns and disposition. Structured capture starts in the eCRF design.
Regulatory variables
Study dates, participant disposition, protocol deviations, safety reporting and device deficiencies. These receive enhanced review because a submission depends on them.
Device-specific risk
Device configuration, software versions, malfunctions, user errors, corrective actions, wearable data and connected device telemetry.
