Safeguarding and non-accidental injury clues

01OverviewDefinition, clinical context and the essential points that orientate the chapter.

Safeguarding is a clinical responsibility to recognise possible harm, treat injuries and activate proportionate protection. Concern arises from the whole pattern: injury, mechanism, development, timing, behaviour, previous records, family or carer interaction and unmet needs. One sign rarely proves abuse and no social stereotype excludes it. Use language such as 'concern that the explanation is unsuitable' rather than declaring guilt, while acting decisively when immediate safety is uncertain.

History is evidence and care. Ask open questions about what happened, when, who was present and what the person could do developmentally. Record the exact words and identify each speaker. Take histories separately when safe and note spontaneous disclosures without repeated interviewing. Explore delay, changes and previous injury calmly. Do not confront a suspected perpetrator or ask leading questions that can distress the patient and compromise later specialist interviews.

Examination is complete, respectful and objective. Treat pain, use a chaperone, explain consent and expose each area while maintaining dignity and warmth. Record size, shape, colour, location and tenderness of injuries on a body map; photographs follow local policy, include a scale and preserve the original file. Examine mouth, ears, scalp, neck, trunk, buttocks, genital or perianal areas only when clinically indicated and with appropriately skilled support.

Paediatric clues are interpreted through mobility and anatomy. Bruising is uncommon in a non-mobile baby. Patterned marks, ear, neck, torso or protected-site bruising, burns with clear immersion lines, bite marks, multiple fractures or different healing stages raise concern. Posterior rib and classic metaphyseal fractures are particularly associated but are not read in isolation. Intracranial and abdominal injury may lack external signs, and normal behaviour does not clear a young child.

Investigation is specialist-led. A child-protection paediatrician coordinates skeletal survey according to age and indication, follow-up images when needed, head CT or MRI, ophthalmology, abdominal imaging and laboratory evaluation for bleeding or bone fragility. Imaging should be acquired and reported by appropriately experienced teams. Medical mimics are investigated seriously, but finding a bleeding or bone disorder does not necessarily explain every injury or remove the safeguarding question.

Adults may disclose domestic, sexual, organisational, carer or financial abuse, or may show neglect through malnutrition, untreated pressure injury, medication omission and delayed care. Speak privately using a professional interpreter rather than a companion. Assess capacity for the specific decision, immediate danger, dependants and coercion. Respect a capacitated adult's choices where possible, while sharing without consent when required by law or necessary to prevent serious harm to them or others.

Close the loop before the patient leaves. Contact the safeguarding lead and statutory service directly, document names, times and advice and agree who can visit, collect or receive information. Preserve clothes, swabs and devices under forensic policy when relevant. At transfer, use clinician-to-clinician handover and confirm receipt. Discharge requires an explicit safe destination and follow-up; an unanswered referral message is not a protection plan.

Key points

Treat life-threatening injury and pain immediately; safeguarding assessment runs in parallel and must not delay CT, surgery, antibiotics or other necessary care.
Record who gave each history, their exact words, timing, developmental abilities, witnesses, changes and previous attendances without accusatory or interpretive language.
Examine the fully exposed patient with consent and chaperone, map every injury, photograph under policy with a scale and record normal as well as abnormal findings.
In children, consider abuse when an explanation is absent or unsuitable, especially with bruising in a non-mobile baby, patterned lesions, fractures of differing age or high-specificity rib and metaphyseal patterns.
Use a paediatrician-led investigation plan: blood tests, skeletal survey, CT or MRI head, ophthalmology and abdominal assessment are selected by age and findings and should not be improvised in isolation.
Speak with a competent adult or developmentally appropriate child privately when safe, use open non-leading questions and never promise absolute confidentiality.
Share necessary information promptly with the named safeguarding lead and children's or adult social care; immediate danger may also require police, while consent is not always required to prevent serious harm.
Do not discharge, transfer or alert an alleged perpetrator without a documented multi-agency safety plan and clear handover of every medical, evidential and statutory action.

02AetiologyUnderlying causes, associations and risk factors, with why each one matters.

Physical abuse

Blunt impact, shaking, twisting, burning, biting, poisoning and fabricated mechanisms produce injury that may be repeated, concealed or attributed to a developmentally impossible event.

Neglect

Failure to provide supervision, nutrition, hygiene, medicines, pressure care or timely healthcare causes preventable injury, illness and delayed presentation.

Domestic or coercive abuse

A partner, family member or carer may use physical, sexual, emotional, financial or controlling behaviour while monitoring access to clinical care.

Fabricated or induced illness

A caregiver may invent symptoms, alter samples, withhold treatment or directly induce illness, producing inconsistent findings and repeated healthcare contact.

03PathophysiologyThe causal sequence from the underlying abnormality to symptoms and harm.

1
Vulnerable anatomy
Infants have large heads, weak necks and compliant ribs, while older and disabled adults have fragile bone, skin and dependence that magnify inflicted force or neglect.
2
Repeated injury
Different healing stages arise when episodes occur over time; repeated brain, rib, metaphyseal, skin and soft-tissue trauma accumulates functional harm.
3
Occult internal damage
Abdominal organ, intracranial, retinal and skeletal injury can be severe despite sparse external signs and apparently normal early observations.
4
Trauma and coercion
Fear, attachment, communication barriers and dependency affect disclosure, recall and behaviour; a calm or protective attitude does not exclude abuse.

04Clinical features and red flagsSymptoms, examination findings, patterns of presentation and time-critical warnings.

Unsuitable explanation

No history, changing account, implausible developmental mechanism, unexplained delay or mismatch between force and injury should trigger structured safeguarding review.

Concerning bruise or burn

Pattern, protected location, non-mobile infant bruising, implement shape, bite, cigarette-like lesion or sharply demarcated immersion pattern requires experienced assessment.

Concerning fracture pattern

Posterior rib, metaphyseal, scapular, spinous-process or multiple fractures of different ages increases concern but must be interpreted with history, imaging quality and bone health.

Occult head or abdominal injury

Vomiting, drowsiness, apnoea, seizure, pallor, abdominal distension, tenderness or raised transaminases may reveal serious internal injury with few skin signs.

Coercive adult context

A companion who answers every question, prevents privacy, controls medicines or money, or produces visible fear may indicate coercion and blocks safe disclosure.

Neglect pattern

Malnutrition, dehydration, poor hygiene, untreated wounds, pressure injury, missed medicines and repeated late presentation can reflect unmet care needs rather than simple non-adherence.

Red flags requiring action

History that changes, is delayed, lacks explanation, conflicts with developmental ability or does not account for injury severity should prompt safeguarding assessment without assuming guilt from one discrepancy.
Bruising in a non-mobile baby, patterned injury, multiple injuries at different healing stages, unexplained fracture, burn, intracranial or abdominal trauma requires urgent senior child-protection evaluation.
Fearful behaviour, controlling companion, repeated delayed attendance, medication withholding, poor hygiene, pressure injury, malnutrition, genital trauma or unexplained financial and care dependence can indicate adult abuse or neglect.

05InvestigationsWhat to request, why it matters and how to interpret it.

Investigation order

Read from the initial assessment onwards. Tests may run in parallel in urgent care; first-line, preferred, confirmatory, definitive and gold-standard labels appear only when the chapter explicitly states them.

01
First-line full clinical and record reviewFirst stepFirst line
Why
Define injury, development, chronology and previous concerns.
Interpretation and limitations
Reconcile ambulance, primary care, hospital and social information through the safeguarding pathway; absence of prior records does not prove absence of prior harm.
02
Paediatric skeletal survey
Why
Identify occult and healing fractures in the age and concern groups specified by child-protection standards.
Interpretation and limitations
Acquire and report through an experienced paediatric radiology protocol; follow-up views can clarify occult injury and healing and are not replaced by a babygram.
03
CT or MRI head
Why
Detect acute and evolving intracranial injury where inflicted trauma is suspected.
Interpretation and limitations
Use urgent CT for acute life-threatening questions and MRI for additional brain, spine and dating information according to the paediatric multidisciplinary plan.
04
Ophthalmological assessment
Why
Document retinal and ocular injury in selected suspected abusive head trauma.
Interpretation and limitations
A suitably experienced ophthalmologist performs dilated assessment at the clinically appropriate time; absence of retinal haemorrhage does not exclude abuse.
05
Bleeding and bone-health tests
Why
Evaluate clinically plausible medical contributors to bruising and fracture.
Interpretation and limitations
Select FBC, coagulation and specialist factor or metabolic testing with haematology or bone expertise; results are interpreted against the complete injury pattern.
06
Abdominal screening and imaging
Why
Find occult solid-organ or hollow-viscus injury.
Interpretation and limitations
Use examination, transaminases, pancreatic tests, urinalysis and contrast imaging according to signs and specialist advice; a quiet abdomen does not exclude early injury.

06Differential diagnosisRealistic alternatives and the features that help distinguish them.

Accidental injury

Developmentally plausible witnessed trauma with consistent history may explain findings, but severity, distribution and other injuries still require reconciliation.

Bleeding disorder

Coagulation and platelet disease can cause bruising or intracranial bleeding and must be investigated when indicated without treating a medical diagnosis as automatic exclusion of abuse.

Bone fragility

Osteogenesis imperfecta, rickets, prematurity, metabolic bone disease and osteoporosis can predispose fracture; specialist bone assessment and safeguarding review may both be needed.

Dermatological mimic

Birthmarks, cultural practices, infection, vasculitis and photodermatoses can resemble bruises or burns and require experienced skin assessment.

Benign development and behaviour

Normal bruising rises with mobility and bony prominence exposure, while developmental history determines whether the proposed mechanism is possible.

07ManagementImmediate care, first-line treatment, alternatives and escalation.

01ImmediateTreat and preserve safetyFirst stepAn injury or disclosure raises possible abuse, neglect or immediate danger.

1Run ABCDE, provide analgesia and complete time-critical imaging or surgery while alerting senior clinical and safeguarding staff.
2Separate the patient from a suspected perpetrator when safe, use a professional interpreter and ask open non-leading questions.
3Document exact words, developmental context, full examination, body maps and policy-compliant photographs and preserve forensic material.
4Contact statutory safeguarding services and police for immediate danger under the local pathway, recording the name, time and agreed safety action.

02ChildCoordinate specialist investigationA child has concerning injury, unsuitable explanation or suspected neglect.

1Involve a senior paediatrician with child-protection expertise and review previous health, developmental and safeguarding information.
2Use the age- and finding-specific skeletal survey, neuroimaging, ophthalmology, abdominal and laboratory plan rather than isolated ad hoc tests.
3Investigate bleeding, bone and dermatological mimics where plausible while maintaining protection and multi-agency assessment.
4Do not discharge until children's social care and the clinical team agree a documented safe placement, information plan and follow-up.

03AdultSupport disclosure and choice safelyDomestic, sexual, carer, institutional or neglect concerns arise in an adolescent or adult.

1Offer private conversation, assess immediate danger, capacity, coercion, dependants and access to medicines, money, housing and communication.
2Explain confidentiality and its limits, offer independent domestic or sexual-assault support and preserve forensic options without pressuring a decision.
3Share necessary information with adult safeguarding or police when consent is given, law requires it or serious harm to the patient or others must be prevented.
4Create a discreet contact, discharge and follow-up plan that does not expose the patient to retaliation through messages, paperwork or companions.

08ComplicationsImportant consequences, why they occur and why they matter clinically.

Recurrent or fatal injury

Missed safeguarding concerns can return a child or dependent adult to escalating violence, poisoning, neglect or lethal head and abdominal trauma.

Neurological disability

Inflicted brain and spinal injury can cause epilepsy, visual loss, cognitive impairment, motor disability and long-term developmental effects.

Chronic psychological harm

Fear, attachment disruption, post-traumatic stress, depression, self-harm and impaired trust can persist after physical injuries heal.

Legal and evidential harm

Speculative notes, poor photographs, lost clothing or unrecorded exact words can impair both clinical continuity and fair statutory investigation.

Unsafe family separation or confrontation

Confronting a suspected perpetrator without a plan can increase danger, prompt disappearance or prevent private disclosure and safe discharge planning.

09Monitoring and follow-upTreatment response, safety checks and longer-term review.

Repeat neurological, abdominal, skin and pain assessment because occult inflicted injury can evolve after the first examination.
Track every safeguarding referral to confirmed receipt, named worker, decision and safety plan rather than relying on an unanswered electronic form.
Reconcile all imaging and laboratory results, including follow-up skeletal survey and final radiology reports, with the responsible paediatrician.
Document visitors, private conversations, capacity, consent, information shared and any attempt to remove the patient before assessment is complete.
At transfer or discharge, confirm safe destination, transport, medicines, appointments and how the patient or carer can seek help without increasing risk.

10Special situationsVariants, exceptions and circumstances that change the usual approach.

Concern is cumulative

Mechanism, development, pattern, timing and prior history strengthen or weaken concern together; one sign rarely carries the entire conclusion.

Exact words outperform labels

Objective quotation and description supports fair clinical, social and legal interpretation better than speculative terms such as suspicious parent.

A mimic can coexist

Bleeding or bone fragility may increase injury but does not automatically explain every lesion or exclude inflicted harm.

Privacy is an intervention

A safe private conversation with a professional interpreter can reveal coercion that is invisible while a controlling companion remains present.

Referral is not closure

Protection begins only when the receiving statutory service confirms responsibility and an explicit immediate safety plan.

11Common pitfallsFrequent interpretation and management errors.

01
Delaying life-saving injury treatment until a safeguarding history is complete.
02
Asking repeated leading questions or confronting an alleged perpetrator without a safety plan.
03
Interpreting one fracture or bruise as proof while ignoring development, mimics and the whole pattern.
04
Using a single babygram instead of the specialist skeletal-survey protocol.
05
Promising absolute confidentiality before explaining the duty to share information for serious harm.
06
Discharging after submitting a referral without confirmed receipt and a safe destination.
