The Trauma Load Index

The Trauma Load Index

Burnout, sickness and resignation in UK ambulance and police control rooms aren't random, they follow patterns that can be measured. The Trauma Load Index is FourNet's workforce intelligence framework, built on 30 years of peer-reviewed occupational psychology and fatigue science. For the first time, it gives supervisors and operations leaders a real-time, objective measure of cumulative psychological load — call by call, shift by shift, agent by agent.

The Hidden Crisis

Sickness, attrition and burnout aren't random events. They are predictable, measurable, and preventable.

  • 35%

    Annual attrition in police force control rooms

    Nearly double the NHS overall average. Some trusts exceed 12%.

  • 9.6%

    Average sickness absence in UK ambulance control

    After frontline response, the largest contributor to police workforce loss.

  • 46%

    Of controllers exhibiting symptoms of Secondary Traumatic Stress Disorder.

    After frontline response, the largest contributor to police workforce loss.

  • £32k

    To recruit and train one operational replacement

    A 200-seat control room is losing £4–4.5 million a year to a problem nobody is measuring.

What the Trauma Load Index Measures

Six dimensions, scored automatically. Per contact, per shift, per rolling 28 days. 

Every contact is scored automatically across six observable variables, using data already flowing through the workforce management and contact centre estate. No surveys. No self-report. No new data collection.

Acuity

Clinical or incident severity. Cardiac arrest, threat-to-life, mass casualty incidents escalate the score.

Distress

Caller emotional state, detected through speech analytics. Calm, anxious, distressed, hysterical.

Content

Nature of the incident. Self-harm, paediatric trauma, domestic violence carry weight.

Time

Extended call duration amplifies emotional load and reduces recovery between contacts.

Repetition

The same high-acuity type back-to-back compounds load. The second cardiac arrest call is not the same as the first.

Outcome

Known adverse outcomes (death, serious injury) add weight retrospectively.

What it produces

Supervisors see one screen, updated continuously throughout the shift. Every TLI score, every fatigue flag, every recommended action — visible in real time and audit-ready for HMICFRS and NHS England governance.

Built on the Science

Thirty years of peer-reviewed evidence - operationalised for the first time. The Trauma Load Index is not a wellbeing trend. It is the operationalisation of three decades of occupational psychology, fatigue science and emergency-services workforce research. The Maslach Burnout Inventory, the Demerouti / Bakker Job Demands–Resources model, Folkard & Tucker's working time research, Figley's compassion fatigue and Secondary Traumatic Stress Disorder, Kecklund & Axelsson on quick-return harm — all of it directly inputs the framework. The science was settled. What was missing was a platform that turned it into a daily operational tool. That's what FourNet has built. 

Why FourNet

We work both sides of the line.

FourNet is the only UK technology partner treating customer vulnerability and agent vulnerability as one connected safeguarding responsibility. Two years of vulnerability research now underpin our customer-side category library – bereavement, carer pressure, suicidal ideation. The same discipline now applies to the agent. Our framework is vendor-agnostic, partnered with Anthrolytics for the predictive engine, and deployed live in 999 control rooms, NHS trusts, police force control rooms, housing associations and debt advice charities. Every place where vulnerability is the whole job, not a feature.
