Suspected non-accidental injury: mandatory reporting

Suspected non-accidental injury: mandatory reporting

By Dr. Shannon KendrickUpdated September 2026

The case

A 4-year-old boy is brought in with multiple bruises of different colours on his buttocks, thighs and arms. He attends daycare 3 days a week. His mother says he is clumsy. There is no developmental delay. Coagulation studies (PT, APTT) and platelets (280 × 10^9/L) are normal. The bruises are non-tender and some show finger-mark patterns. He becomes withdrawn when asked about them. There are no retinal haemorrhages. What is the most appropriate management?

Options

  1. ANotify the child protection service of suspected abuse
  2. BArrange a haematology review for a bleeding disorder
  3. CDischarge with advice on preventing bruises
  4. DObserve in hospital while daycare CCTV is reviewed
  5. EGive vitamin K and review in clinic

Think it through before you read on. Which single option is best, and why are the other four wrong?

Answer

A. Notify the child protection service of suspected abuse

Why this is the right answer

The pattern here is highly suspicious for physical abuse. Accidental bruises in a mobile child occur over bony prominences: shins, knees, forehead. Bruises on the buttocks, thighs and upper arms, in several stages of healing, with finger-mark patterns, do not fit 'clumsiness'. A child who goes quiet when asked about injuries is another warning sign. Normal coagulation studies have already excluded the main medical alternative.

In every Australian state and territory, doctors are mandatory reporters of suspected child abuse. The threshold is a reasonable belief or suspicion that a child has been, or is at risk of being, physically or sexually abused (the exact categories vary between jurisdictions). The doctor does not need proof, does not need to identify the perpetrator, and must not investigate before reporting. Reporters who act in good faith are protected from liability and their identity is confidential.

The report goes to the state child protection service (for example, the Department of Communities and Justice in New South Wales, or Child Safety in Queensland) by phone and in writing. In a hospital, the child protection unit or social work team is involved at once. The child is examined fully, injuries are documented with body maps and photographs, and a skeletal survey is considered in children under 2. Admission is appropriate if the child is not safe to go home while the assessment proceeds.

The RACGP White Book (Abuse and violence: working with our patients in general practice) sets out the general practitioner's role and emphasises that the duty to report overrides confidentiality.

Parents are told, in a non-accusatory way, that the doctor is required to report injuries of this kind, unless doing so would put the child at greater risk.

Why the other options are wrong

B

Clotting and platelets are already normal; a haematology referral delays the mandatory report.

C

Sending the child home without protection is a failure of the duty to report and to protect.

D

Investigation is the job of child protection services; the report must not wait for evidence gathering.

E

Vitamin K treats coagulopathy, which has been excluded; it is irrelevant here.

High-yield takeaway

Bruising in unusual sites, of different ages, with a patterned shape or an inconsistent history triggers a mandatory report to child protection; suspicion is enough, and reporting comes before investigation.

Common questions

Do I need proof before reporting suspected child abuse?

No. A reasonable suspicion is enough. Investigation is the job of the child protection service, not the doctor.

Can I be sued for making a report?

Reporters acting in good faith are protected from civil and professional liability in every state and territory, and their identity is kept confidential.

Try twenty of these, unmarked.
