Solution · Care Journal Cohort
Recruit the exact patients,
then keep asking.
Some questions deserve a cohort built for them. Recruit and consent the exact population, run your own ePROs, and follow the same people month after month.
IRB-ready. Your instruments, your schedule. Live dashboards while it runs.

Why Cohort exists
Some questions deserve their own cohort.
Rare subtypes, tolerability and adherence, outcomes that only appear if you follow them forward, and a population you can go back and ask again. This is how you get all four.
We recruit
Matched to your criteria, from people already using Care Journal.
They consent to you
Named study, plain language, withdrawable at any time.
expires after 12 months
You keep asking
Your ePROs on your schedule, month after month.
What you get
Your own registry, running
on real-time data.
Matched patients enrolled with their linked records already behind them, your instruments running on your schedule, and an IRB-ready setup you can hand to your compliance team.

Custom consented cohorts
We recruit and consent the exact population you need, each one arriving with their linked history already assembled.
Your own ePROs
Licensed instruments or your own questions, on the cadence you set. Symptoms, side effects, adherence and daily logs.
Followed forward
Follow the same people forward. You watch a signal build, in time to act on it.
IRB-ready
Consent flows, custom logic, live dashboards and export-ready longitudinal data.
What you can do with it
Three jobs that need a living cohort.
HEOR: quantify productivity loss, out-of-pocket cost and resource use, and catch adherence dropping before it shows up in outcomes. Market Access: collect tolerability data your value dossier needs. Field: territory-level symptom dashboards your MSLs can actually use.
We ask, they answer
You mentioned the fatigue got worse after cycle three. Did anything change that week?
I started the new anti-nausea tablet on the Tuesday.
When to use Archive instead
Cohort is for what happens next.
When your question is about care that already happened and the patients are in there, Care Journal Archive is faster and cheaper.
Care Journal Archive
Query the history that exists.
- Structured fields plus the notes behind them
- Cohort-matched to your inclusion criteria
- De-duplicated across systems, so one person counts once
- De-identified and analysis-ready in days
Care Journal Cohort
Recruit the cohort and follow it.
- Recruit and consent the exact population you need
- Your own ePROs, on your schedule
- Prospective follow-up, month after month
- Dashboards while it runs, exports when you need them
Participants see who you are before they agree, can withdraw whenever they like, and their consent expires after a year unless they renew it.
Who uses it
Built for the teams who get asked to prove it.
Medical Affairs, RWE and HEOR, Market Access, Commercial Strategy and R&D. Same source, different question depending on where your product is.
Questions we get
What people ask us first.
Ask us anything, including the hard ones. We answer those the same way.
How long does recruitment take?
It depends how specific the population is, and we will give you a real estimate before you commit. Many are already using Care Journal, which is what makes reaching them quick.
Where does the data actually come from?
People use Care Journal for their own reasons. It pulls their records in from the clinics they’ve been to, and they add what’s missing. Later, separately, they can choose to let a de-identified copy go into research.
Will the consent survive a diligence review?
Consented at source, per study, with you named before anyone agrees. People can withdraw whenever they like and it renews yearly by choice. Every record traces back to the moment its owner said yes.
How big is the cohort?
Growing every week. We’re early, and we would rather show you precisely where it stands today and let you judge whether it carries your question.
Do we get the notes, or just structured fields?
Both. Diagnoses, labs, meds, vitals and payer detail, plus the clinical notes, pathology and discharge summaries parsed. And what the person wrote themselves between appointments, kept verbatim.
Who uses this inside a company like ours?
Medical Affairs, RWE and HEOR, Market Access, Commercial Strategy and R&D. Usually it starts with one team’s question and the file ends up getting passed around.
Tell us who you need to reach.
We’ll show you how many we can reach, how long recruitment takes, and what it costs, before you commit to anything.
