Cairn

Behaviour that challenges · formulation · care planning

The formulation that shows its working.

Cairn helps care teams record what happens, see which patterns the records actually support, and write a formulation and care plan that a qualified professional reviews and signs off. Every number opens the records behind it. Nothing is interpreted for you.

No card needed for the trial. Works fully with AI switched off. Documentation support, not a clinical decision tool.

Cairn's analysis screen for a fictional person: 34 incidents in the period, trend increasing, busiest band early morning 06–09 at 44%, top antecedent washing or bathing, and the approach that appears to help: deferred care and returned later.
The analysis screen. Fictional test data; every figure is a link to the records it was computed from.

A worked example

Ninety days of ABC records. Fifteen questions. One honest answer.

Arthur is a fictional resident with dementia. Over ninety days his team recorded 34 incidents on the ABC form Cairn provides: what happened before, what he did, what staff did, how it ended. Cairn then asked the fifteen questions a good formulation always asks, and answered each one only from those records.

  • 18 of 34incidents were during or just after personal care, most of them in the early morning.
  • 6 of 6times that care was continued after refusal, or two staff went hands-on, the distress escalated.
  • 12 of 12times that care was deferred, slowed, or a different carer returned later, Arthur settled.
  • 4 of 5incidents where pain signs were assessed showed moderate or severe signs.
  • 0 of 8PRN doses were recorded as fully effective.

Two hypotheses surfaced with that evidence attached: a personal-care association and possible pain. Seven more were flagged for the reviewer to rate. Six were not supported by the records and say so. The care plan that follows is built from the same numbers: what to watch for, what to do first, what to avoid, what to do if it escalates, and how the team will know it is helping.

Cairn's formulation screen: hypotheses H01 to H15 listed in fixed order with their evidence, H01 personal care association rated Supported, with a draft statement, evidence lines and the records behind each.
The formulation screen. The reviewer rates every surfaced hypothesis, amends any wording, and signs off. Sign-off is blocked until they do.

How it works

Record. See. Formulate. Plan. Hand over.

Record

Staff enter ABC incidents, symptom reviews, medication events, interventions and what-helps ratings from a shared vocabulary. Families contribute through a secure form. Paper records and the Formulation Builder workbook import directly.

See

Nineteen analysis sections — by behaviour, time of day, activity, antecedent, location, pain, PRN, medication, symptom change, approach evidence — computed from the records, with checks that flag what is missing before anyone relies on it.

Formulate

Fifteen hypotheses in a fixed order, each surfaced or not surfaced by published thresholds, each with its evidence and a “how this was decided” trace. The reviewer rates, amends and signs off. Nothing is a formulation until they do.

Plan

A care plan built from the signed-off formulation: presenting need, goals in the person's own voice, interventions chosen from the library with this person's evidence beside each one, what to avoid, escalation, how you'll know, review date.

Hand over

Hospital, transfer and discharge handovers populated from the records and the signed-off formulation. Eight Word reports, including a regulator evidence pack. PDF and Word exports with identifiers added only at the moment of export.

Five care profiles, one engine

The framework your service already uses.

Each profile sets the symptom domains, the person-profile emphasis and the eight headings of the formulation document. The rules are the same for everyone, so a dementia unit and a supported-living service get the same rigour in their own language.

A person can carry a secondary profile, for example autism with a learning disability. Used in inpatient, residential and community settings.

What comes out

Documents a manager, a family and an inspector can all read.

Per person

  • Formulation & Plan (Word and PDF) under the profile's eight headings
  • Care plan, one section per need, with the evidence for each intervention
  • Hospital handover: red flags, communication, signs of distress, what helps, what makes things worse, medication alerts
  • Transfer and discharge handovers
  • One-page “About me” profile
  • Care Needs Summary · Behaviour Trend · Medication Review · Intervention Effectiveness · Regulator Evidence Pack
  • Blank paper forms (ABC, symptom review, behaviour profile) for the floor

Across the organisation

  • Antipsychotic Stewardship: target symptom recorded, months since start, latest adverse-effect scores, PRN use
  • Care Complexity: records, hypotheses, checks and review-due status per person
  • Incident Summary by Period: per unit, per time band, per behaviour

Every report ends with a section on how it was produced. None of it is interpreted.

Built to be trusted

Rules, not opinions. Records, not identities.

Deterministic

Same records, same thresholds, same result, every time. Every hypothesis carries the counts, the shares and the threshold it was compared against.

Never a clinical decision

Cairn does not diagnose, score a person, recommend a drug or a dose, hide a hypothesis or rank one above another. The clinician decides; Cairn shows its working.

Minimal identity

A person is a local reference and a preferred first name. No surname, date of birth, NHS or hospital number, address or photograph is stored. Identifiers for a printed document are typed at export and never kept.

Audited and separated

Row-level security on every table; an append-only audit log of every change; each organisation sees only its own data. Discharge removes the clinical records and keeps the audit trail.

Accessible

Built to WCAG 2.2 AA, keyboard-operable throughout, usable on a phone at 360 pixels wide.

AI only if you choose it

Optional drafting and scanning assistants, off by default, opted in per organisation and per user, with the cost shown before every call. With AI off, every screen and export works identically.

Cairn is a documentation support tool. It is not a clinical decision tool and is not a medical device. An intended-purpose statement, a hazard log and a data-protection pack for your own DPIA are available on request.

Pricing

Founding pilot, autumn 2026

Cairn is a pilot release. A small number of services get ninety days free and 30% off for as long as they stay, in return for honest monthly feedback and a short case study. Support is by email, Monday to Friday, within two working days.

Questions

Straight answers.

Is Cairn a medical device?

No. Cairn is a documentation support tool. It records, counts and reports; it does not diagnose, treat, recommend medication or make any clinical decision. A qualified professional reviews and signs off every formulation and care plan. The intended-purpose statement is available on request.

Does it replace our care-planning system?

No. Cairn sits beside whatever you already use and does one job thoroughly: behaviour recording, formulation and the care plan and handovers that come from it. Documents export to Word and PDF so they can be filed wherever your records live.

Where is the data held, and who can see it?

In a managed PostgreSQL database with row-level security, so each organisation sees only its own data, and an append-only audit log of every change. Cairn stores a local reference and a preferred first name only; nothing else identifying. A data-protection pack describing the data items, flows, retention and processors is available for your own DPIA.

What happens when the trial ends?

If no plan is chosen the organisation becomes read-only: nothing is deleted and exports still work. Choose a plan at any time to carry on.

We already use the Formulation Builder workbook.

Cairn uses exactly the same vocabulary and codes, so a workbook imports in bulk with a per-row check before anything is saved. The Builder remains available as the offline, one-off licence version.

Does it use AI?

Only if your organisation and the individual user both opt in, function by function. The assistants draft wording, summarise or read a scanned paper chart into rows for review; they never generate, rank or rate a hypothesis. The person's name is replaced before anything is sent, the cost is shown before every call, and with AI off nothing in Cairn changes.

Which countries?

The UK, Ireland, Australia and the United States, with spelling and terminology set per organisation. Prices are in GBP; local currency on request.
