Sleep medicine trialsUpdated September 28, 2026

EDC built for sleep disorder clinical trials

Sleep medicine studies, from insomnia to sleep apnea interventions, depend on consistent nightly self-report alongside clinician-administered instruments. Capture pairs a ready-made sleep diary template with scheduled validated questionnaires and clinician CRFs, so nightly data and visit data sit in one dataset instead of a separate diary tool.

  • Nightly sleep diary template
  • Validated questionnaire scheduling
  • One platform for EDC, ePRO, eConsent

Nightly self-report

A sleep diary template ready to adapt, not build from scratch

The template library includes a ready-made sleep diary you can copy and edit for your protocol's specific questions, rather than building a nightly diary form from a blank page.

  • Copy and adapt the existing sleep diary template at /templates
  • Scheduled delivery on the cadence your protocol needs, nightly or otherwise
  • Participants complete it from a link on their own phone, no app install

Validated instruments

Administer the same instrument consistently across visits

Sleep trials typically depend on validated severity or sleepiness questionnaires administered on a fixed schedule. Capture keeps each instrument's structure and response options consistent so scoring is not undermined by inconsistent entry.

  • Configurable visit windows keep an instrument on schedule across baseline, active treatment and follow-up
  • Required fields and consistent response options across every administration
  • Clinician-administered assessments built as structured visit forms alongside participant-reported ones

Device usage & safety

Document device usage and safety events in the same dataset

For studies involving a sleep therapy device, Capture provides structured CRF fields to document device usage hours and compliance as reported or as entered by the site, alongside adverse event capture, rather than a separate manual log.

  • Structured CRF fields for device usage and compliance percentage
  • Adverse event forms with onset, severity and relationship to the intervention
  • One audit trail across diary, questionnaire, CRF and safety data

FAQ

Questions teams ask before they switch

Something not covered here? Ask us directly.

Is there a ready-made sleep diary?

Yes. The template library includes a sleep diary you can copy and adapt at /templates.

Do participants need to install an app for the nightly diary?

No. Participants complete scheduled diaries from a link on their own phone.

Can we administer a validated sleep questionnaire on a fixed schedule?

Yes. Configurable visit windows keep an instrument on schedule across baseline, active treatment and follow-up, with consistent required fields and response options each time.

Does Capture sync directly with a CPAP or sleep-tracking device?

Capture provides structured CRF fields to document device usage and compliance as reported for your protocol. Confirm any specific device integration with us directly before assuming automatic sync.

How are adverse events tracked in a sleep trial?

Through structured AE forms with onset, severity, seriousness and relationship to the intervention, alongside the diary and questionnaire data in the same audit trail.

What does it cost to try?

Nothing to start. The free sandbox has no credit card and no time limit. You pay only once you go live with real participant data.
