Preventative outreach intelligence · Lambeth PCN pilot

Finding the people no one is reaching.

The Missing Million helps social prescribers identify early signs of isolation among older adults — before crisis point — using weak signals already held across care and community systems.

The problem

Isolation rarely arrives loudly. It accumulates quietly, in signals nobody reads together.

A missed appointment. A bereavement quietly noted in one system. A prescription left unfilled. Each looks ordinary on its own. Together they describe a person slipping out of view — months before anyone is alerted.

The Missing Million model

How The Missing Million works

From scattered signals to earlier human contact.

01

Detect

The Missing Million reads weak signals already held across primary care, community and council systems — missed appointments, bereavement, living alone, reduced prescription pickup, declining engagement.

02

Prioritise

Transparent, explainable risk scoring surfaces residents most likely to disengage — with every contributing factor visible and traceable to its source.

03

Reconnect

Outreach guidance helps social prescribers make earlier, more sensitive human contact — informed by context, never replacing judgement.

A glance inside

Quiet, focused, operationally believable.

The Missing Million is built for the rhythm of real outreach work. A single clear priority list. Explainable scores. Sensitivity guidance for first contact. No alarms. No noise.

Trust & ethics

Designed for trust, not surveillance.

The Missing Million supports human judgement. It does not replace it. Every score is explainable, every signal traceable, every outreach decision made by a person.

Human-in-the-loop

Every recommendation is reviewed by a social prescriber before any action is taken.

Explainable scoring

Each risk score breaks down into named, weighted factors traceable to their data source.

Data stays within the PCN

No data leaves your network. No external sharing. No third-party model training.

Not a diagnostic tool

The Missing Million prioritises outreach. It makes no clinical judgement and replaces no clinical pathway.

Manual override

Practitioners can dismiss, deprioritise or annotate any flag — and the system learns from it.

Ethical safeguards

Opt-out by default for excluded categories. Bias audits on every model release.

Outcomes

Earlier contact. Lighter touch. Stronger continuity of care.
