A clinic that wants to say anything credible about its results needs structured data first: the same measures, at the same intervals, with consent and a record of every change. Capture runs a clinic outcomes registry with research-grade controls, without a research department.

What this page is, and is not, about
The problem
A longevity clinic collects a lot: blood panels, body composition, blood pressure, fitness tests, sleep and wearable summaries, questionnaires. In most clinics it sits in an electronic health record designed for billing and care notes, in lab PDFs, in a wearable dashboard and in spreadsheets kept by whoever runs the programme. Pulling a consistent before-and-after dataset out of that means weeks of manual work, and nobody can say afterwards who corrected which number.
That matters because a clinic's credibility is built on its data. A clinic that wants to publish a case series, present at a conference, support a partnership or simply stop relying on anecdote needs the same habits a research team has: a fixed list of measures, fixed time points, defined units, a record of changes and documented consent. Capture is built around exactly those habits. You define the registry once, staff enter data in a browser against the schedule, and members complete questionnaires on their phones between visits.
Structured capture
Build each panel as a site form: numeric fields with units and plausibility ranges, dropdowns for categorical findings, calculated fields such as BMI, MAP or eGFR shown read-only during entry. A value outside the range you set raises a query automatically, so a mistyped glucose or a swapped unit is caught at entry rather than at the analysis stage. Lab tables with analytes as rows can be drafted by the AI form builder from a lab report layout, then reviewed by a person before use.

Member-reported data
Members receive a link, answer a short wellbeing, sleep or energy questionnaire in the phone browser, and reminders chase late responses. Where a member agrees, they can connect their own Oura account through the vendor's sign-in and data syncs automatically into the registry, with last-sync time visible to staff. Oura is the only device Capture names today; confirm any other device with us before you plan around it.

Credibility
Outsiders judge clinic data on a handful of questions. Were the measures defined in advance? Were they taken the same way every time? Is the denominator clear, meaning how many members started and how many have follow-up? Who entered each value, and can it be shown that nothing was edited silently? Is there documented consent for using the data? Capture helps with each: fixed forms, a visit schedule with windows, a dashboard showing completion by time point, a field-level audit trail recording user, time, old value, new value and reason for change, and eConsent with a signed PDF export.
Be careful about what you conclude from the result. Members of a concierge programme are a self-selected group who may differ from the general population, and a before-and-after change in a clinic cohort can reflect many things besides the programme. Report the number who dropped out, describe the measures as they were taken, and avoid wording that implies a treatment effect or a health benefit unless a controlled design supports it. Medical and advertising claims are regulated in most jurisdictions; check your wording with the relevant professional before it goes on a website.
A registry where only the happiest members return for month-12 testing overstates results. Track follow-up completion by time point on the dashboard and report it alongside any change in a measure.
If you want to test whether an intervention works, rather than describe what members' measures did, you need a comparison and usually ethics approval. Capture supports that too, with randomization and blinded roles; see how to run a longevity clinical trial.
Privacy and access
Clinics hold identifiable health information. Capture is built so analysis does not need it.
Site coordinators see participant names; researchers see coded IDs. A data analyst can work on outcomes without seeing who the members are.
Read moreAccess rules are enforced in the database layer, not only in the interface.
Data is hosted in the EU (Frankfurt) or the USA (N. Virginia). Capture describes its infrastructure as HIPAA and GDPR ready; your own legal obligations remain yours.
Clinical data is soft-deleted, never silently destroyed, so corrections stay traceable.
Both uses are possible. For a clinic, the usual pattern is an outcomes registry: fixed measures at fixed time points with consent and an audit trail. If you want a controlled study, Capture also provides randomization and blinded roles.
Not on this data alone. Without a comparison group, before-and-after changes cannot show cause and effect. Capture makes the data consistent and auditable; the interpretation and any public wording are your responsibility, and health claims are regulated.
Documented consent for data use is good practice and often a legal requirement, depending on where you operate and how the data will be used. Capture provides eConsent with on-screen signature and a signed PDF. Take advice from your ethics reviewer or privacy counsel.
Yes, for Oura. The member connects their own account through the vendor sign-in and data syncs automatically. Confirm any other device with us before planning around it.
You can enter them as site forms against a baseline visit. The AI form builder can draft a lab table from a layout or uploaded file for review. Capture does not claim an automatic electronic health record integration.
Site coordinators see names; researchers and analysts work with coded IDs. Access is enforced at the database layer.
The sandbox is free, with every feature, no credit card and no time limit. You pay only once you collect data from real members.
Define your measures, test the member check-ins on your own phone and see the audit trail. You pay only once real members are in.
