Looking at Clinical ink alternatives? Compare how data gets captured

Whether data is entered by sites, participants or clinicians, the questions are the same: how fast can you build, where does the data live, and what does it cost at your study size. Here is what to compare and where Capture fits.

The short version

  • Clinical ink provides technology for capturing clinical trial data at sites and from patients, including eSource and eCOA.
  • Teams compare alternatives when they want to build studies themselves, keep site and participant data in one system, or need pricing that fits smaller studies.
  • Key questions: who builds and amends forms, how clinician-rated scales are handled, what device model participants use, and how data reaches analysis.
  • Capture keeps EDC forms for sites, ePRO for participants, clinician-rated site forms, eConsent and randomisation in one study with one audit trail.
  • Test with your own protocol before deciding.

Why teams compare

Where the data is entered matters less than where it ends up

Clinical trial data comes from several places: site staff entering visit data, clinicians rating scales, participants completing questionnaires at home. Some tools specialise in one of these; others combine them. The more systems involved, the more reconciliation, the more audit trails to review, and the more contracts to manage.

Capture handles clinician-reported outcomes as site forms, participant-reported outcomes on participants' own phones, and performance outcomes as site forms with units and range checks, all in the same study. See clinical outcome assessment types for how these fit together.

Direct entry at the site

Many sites enter data into the EDC during or straight after the visit, with paper or electronic health records as the source. Define in your monitoring plan what the source is for each data point, so monitors know what to verify.

In Capture

Every outcome type in one study

Sites enter visit data and clinician ratings on locked, approved forms with edit checks that raise queries at entry. Participants complete questionnaires on their own phones. Monitors verify the fields that matter, set per field, and every change is in one field-level audit trail.

  • ClinRO, PerfO and ObsRO as site forms.
  • PRO on participants' phones.
  • SDV per field and queries at entry.

Switching

Planning a move

The natural time to switch is between studies. Export your form specifications and instrument lists from the current system, and use them to draft the new study: Capture's AI can draft forms from an uploaded file or description for your review. Licensed instruments need licence holder approval for the new electronic version.

Keep historical data in its original export and merge it at analysis if needed, rather than migrating mid-study. See how to switch EDC vendors mid-study.

Source data

Planning source documents

Wherever data is captured, sponsors must know what the source is. When sites enter data directly into the EDC during the visit, the eCRF itself can be the source for some data points; FDA has published guidance on electronic source data in clinical investigations. When data is transcribed from medical records, those records are the source.

Document the source for each data point in a source data agreement or the monitoring plan, so monitors know what to verify and where. SDV set per field then focuses verification on the data that matters. See source data verification.

FAQ

Questions teams ask before they switch

Something not covered here? Ask us directly.

Can the eCRF be the source document?

For data entered directly during the visit it can be; document the source for each data point.

Is there guidance on electronic source data?

Yes. FDA has published guidance on electronic source data in clinical investigations.

Who is this Clinical ink alternatives page for?

Sponsors, CROs and academic teams comparing eCOA and site data capture options, including teams using or evaluating Clinical ink, who want to see a self-serve, unified option alongside it.

Does this page compare features line by line?

No. Vendors change their offerings, so we describe what to evaluate and where Capture fits. Confirm current capabilities and terms directly with Clinical ink.

Can I test Capture before deciding?

Yes. The free sandbox has every feature with sample data, no credit card and no time limit.

Can clinician-rated scales be captured in Capture?

Yes, as site forms with permitted values, the rater recorded and a field-level audit trail.

Are EDC and ePRO in one system?

Yes. EDC, ePRO, eConsent and randomisation share one study and one audit trail.
