Finding patterns in scattered records.
Medico-legal records come from various sources and were created for different purposes. Early indicators may appear in emergency notes, GP consultations, physiotherapy records, medication changes and rehabilitation reports. No individual professional may see the full sequence.
An AI system using natural-language processing could search those documents for repeated references to disturbed sleep, panic, intrusive memories, avoidance, irritability, low mood or deteriorating function. It could place relevant entries into a chronology and alert a clinician or claims professional that further enquiry may be appropriate.
Research has shown that machine-learning models can use electronic health-record information to identify groups at increased risk of later trauma-related disorders. In one large study following hospitalisation for sepsis, the highest-risk tenth identified by the model accounted for almost one-third of later trauma- and stressor-related diagnoses. The setting was not personal injury litigation, but it demonstrates how routinely collected information might support targeted follow-up.
Screening is not diagnosis.
AI can identify words and patterns associated with psychological symptoms. It cannot determine reliably, from records alone, whether those symptoms satisfy the criteria for post-traumatic stress disorder, adjustment disorder, depression, specific phobia or another condition.
NICE guidance on PTSD requires consideration of the nature of the event, re-experiencing, avoidance, hyperarousal, altered mood and thinking, and functional impairment. It also recognises active monitoring where symptoms are present, but the position is not yet settled. A risk alert might help ensure those questions are asked. It cannot answer them.
A claimant may sleep badly because of pain, medication, financial pressure or an unrelated family event. They may avoid driving because their vehicle has not been replaced rather than because of travel phobia. AI may notice the behaviour but cannot establish its meaning without context.
Early identification should therefore lead to proportionate human review, not an automated label.
Why earlier recognition may matter.
Psychological symptoms can affect recovery even where the original injury is physical. Fear may reduce movement; travel anxiety may obstruct return to work and low mood may weaken engagement with rehabilitation. Earlier recognition may also result in symptoms and their effect on daily life being recorded closer to the time they first developed, making the later medical history easier to assess.
That does not mean every expression of distress requires specialist referral. Many understandable reactions settle naturally. The value of AI would lie in identifying which cases warrant another question, not in converting ordinary distress into psychiatric injury.
False positives and false reassurance.
An AI system may flag people who would recover without intervention, leading to unnecessary assessment and anxiety. More concerningly, a low-risk result may provide false reassurance where symptoms are expressed in a way the model does not recognise.
Records are not neutral data. Some people consult frequently and generate detailed notes. Others minimise symptoms, have limited access to care or describe distress through physical complaints. Language, culture, age, disability and literacy may affect what is recorded.
Models trained in one hospital or patient population may perform poorly elsewhere. Research examining the transfer of mental-health prediction systems between healthcare settings has shown that differences in records and service structures can affect performance. A system used in personal injury work should therefore be tested on the documents and population for which it is intended.
The alert must also be explainable. A reviewer should be able to see which entries produced the concern. An unexplained score is a weak basis for referral, treatment or claims-handling decisions.
A claims file is not a clinical consultation.
Claims documents may repeat descriptions copied from earlier correspondence. An algorithm may mistake repetition for independent confirmation. A solicitor’s summary may use diagnostic language that never appeared in the clinical records. A treatment recommendation may be recorded as though the treatment occurred.
The system should distinguish the claimant’s account, clinical observations, provisional diagnoses and established findings. It should link each alert to its original source rather than produce a summary that appears more certain than the documents.
The expert remains responsible for diagnosis, causation and prognosis. AI may draw attention to an inconsistency or symptom pattern, but it should not decide whether the claimant is reliable or whether an accident produced the condition.
Regulation and confidentiality.
A tool claiming to diagnose, treat or manage a mental-health condition may fall within medical-device regulation. MHRA guidance advises users and organisations to examine what a digital mental-health product claims to do, who it is intended for and what evidence supports its performance.
The records used to identify psychological risk contain sensitive health, family, employment and trauma information. The organisation must know where information is stored, who can access it, how long it is retained and whether it is used to train other models.
ICO guidance requires organisations using AI to consider lawfulness, fairness, transparency, accuracy, security and accountability. Data protection should be built into the system from the beginning rather than considered after the claimant’s records have been uploaded.
Identifiable records should not be placed in an unrestricted public chatbot. Nor should a hidden psychological-risk score influence rehabilitation or case strategy without appropriate transparency and human oversight.
What defensible use looks like.
A defensible system would operate as a triage assistant. It would search approved records, identify source-linked indicators and prompt a trained person to review them. A positive result would lead to appropriate questioning or validated screening. A negative result would not prevent assessment where the claimant, their family or the clinical evidence continued to cause concern.
Its performance should be monitored for missed cases and unnecessary alerts. Decisions should be auditable, and users should understand the limitations of the output. The system should never turn a statistical association into a clinical or medico-legal conclusion.
AI can help identify possible psychological injury earlier by gathering clues scattered across a large record and drawing attention to changes that might otherwise be missed.
The useful output is not, “This claimant has PTSD.” It is, “These entries suggest that somebody should ask more.”
The machine may recognise the pattern first. The diagnosis, explanation and response must remain human.
