Data quality in a clinical study is decided by choices your study team makes: how the eCRF is designed, how sites are trained, how fast queries are answered. Datacapt gives you the tools for each of those. The decisions and the timelines are yours.
Before you build
Design clear, user-friendly forms. Keep the layout intuitive for the clinical staff who will use it. Use consistent question formats and wording so the same thing is never asked two different ways. Avoid unnecessary fields: every question you add is a question a site has to answer and a data point someone has to clean.
Set up your edit checks while you design, not after. Validation rules that flag incomplete or inconsistent entries at the moment of entry cost minutes to write. The same error found after 200 subjects costs a query per subject.
Test rigorously, before the study goes Live. Validate the structure and every question with test subjects while the study is in Draft. Once the study is Live the Builder closes, and changing a live study is slower and riskier than getting it right first.
đĄ Tip: document your validation of the eCRF before you publish it. Inspectors ask how the form was validated, and the answer is much easier to produce at the time than to reconstruct two years later.
Prepare the people who will use it
Train clinical staff and investigators on the eCRF itself, not just on the protocol. Cover data entry, what the validation messages mean, and how queries reach them and get answered. A site that has never seen a query notification will not answer one.
Give sites something to refer back to. Guidelines and an FAQ for the situations that come up most reduce the questions that reach you, and the wrong entries that become queries.
Keep communication open between the clinical team, the data managers and the sites, and share progress and timelines so everyone works to the same dates.
While you are collecting data
Monitor completion rather than assuming it. Use the dashboard and the Inclusions list to see which forms are late, set explicit timelines, and follow up with the sites that are behind. A site three visits behind will not catch up on its own.
Resolve discrepancies as they appear. Site staff remember a visit from last week. They do not remember one from last year, and neither do their notes.
Review data on a schedule. One site with an unusual number of queries, or a question everybody answers the same way, usually means the form is unclear rather than the sites careless.
Stay inspection-ready
Confirm the configuration meets the standards that apply to your study, for example FDA 21 CFR Part 11 and GDPR, including who has access to what, which is set by role rather than by user.
Keep the audit trail meaningful. Every entry and edit is recorded automatically. The reason for change option, under Settings > Options > Enable GCP, makes an edit record why it was made, which is the part an inspector asks about.
â ď¸ Warning: the reason for change option cannot be enabled once the study is Live. Decide before go-live whether your study needs it.
When you close the study
Agree the lock process before you need it. Who locks, who signs, in what order, rather than working it out under time pressure at database lock.
Plan the archive at the same time, before the study moves to Ended and everything becomes read-only.
