Photodocumentation and medicolegal evidence — formative SAQs

SAQ 1 — A patterned arm mark in a 4-month-old (10 marks)

A 4-month-old infant presents with coryza. On undressed examination you find a 2 cm ovoid bruise on the outer arm with what appears to be a fingertip pattern. The infant is not yet rolling independently. The emergency department is busy. [3] [5]

Questions

1. Describe how you would photographically document this injury at the bedside. (4 marks) [3]
2. Outline how you would label, store, and govern the images, and why personal-phone storage is unacceptable. (3 marks) [1] [9]
3. Describe how you would record this in the written note, including the fact-versus-opinion distinction. (3 marks) [10] [6]

Model answer

Photographic documentation (4). Photograph before any cleaning, dressing, or procedure because the finding is perishable. Capture the three-shot set defined by the standardised acute-care protocol: an orientation shot placing the bruise in anatomical context on the arm, a mid-range shot of the bruise in relation to landmarks, and a close-up with a scale (ruler or coin) held in the same plane as the injury with the camera perpendicular to the skin to avoid distortion. Use good lighting and repeat any blurred image. Transcribe the finding onto a body map with site, colour, shape, and measured size in two dimensions, and record the infant's developmental mobility in the same note. [3] [5]

Labelling, storage, and governance (3). Label each image immediately with the child's identity, the date, the time, and the anatomical site, and transfer it to the secure clinical imaging system or designated child-protection record. Storage must be access-controlled and audit-logged. Personal-phone or messaging-app storage is unacceptable because the image then lives outside the controlled record, its access is unlogged, its retention unmanaged, and its integrity open to challenge; it may also breach professional and privacy standards. The chain-of-custody principle requires that who accessed the images and when be recoverable. [1] [9]

Written record and fact versus opinion (3). Record the observed findings as fact: the size, site, colour, shape, and patterned quality of the bruise, and the developmental mobility of the infant. Quote the caregiver's mechanism verbatim as their account, not as established truth. Offer any interpretation — that the pattern is consistent with a fingertip grip, or that the mechanism is developmentally implausible — explicitly labelled as opinion with the reasoning. Disclose uncertainty and stay within your competence; you are a witness to fact, not the investigator. [10] [6]

SAQ 2 — The court statement and an unlabeled image (10 marks)

You are asked to prepare a court statement for a child with multiple bruises documented six weeks earlier. Review of the record shows that one close-up image has no scale and another was taken on a clinician's personal phone before later deletion. [1] [3]

Questions

1. How do the scale-less close-up and the personal-phone image weaken the record, and what could have prevented each? (4 marks) [3] [1]
2. Outline how you would structure the court statement, distinguishing fact from opinion and disclosing uncertainty. (4 marks) [10] [6]
3. What quality-improvement measure does the evidence support to prevent documentation failure, and why? (2 marks) [2]

Model answer

Weaknesses and prevention (4). A close-up without a scale is dimensionless; the same image could represent a one-centimetre or a ten-centimetre injury, and a court cannot use it for comparison or sizing. Prevention is the in-plane scale with perpendicular capture as a non-negotiable element of the close-up, embedded in the standardised protocol. A personal-phone image lives outside the controlled record: its access is unlogged, its retention unmanaged, and once deleted it is irrecoverable, so the finding may be lost entirely. Prevention is capture directly onto the secure clinical system, or immediate transfer, with personal-device use prohibited. Both failures reflect improvisation under pressure rather than protocol. [3] [1]

Court statement structure (4). Identify the child and the encounter; state the observed findings as fact (the sites, sizes, colours, shapes, and patterned qualities of the bruises, and the developmental mobility); record the mechanism as the caregiver's verbatim account; and offer any opinion — for example that the distribution is consistent with inflicted injury and inconsistent with the offered mechanism — explicitly labelled as opinion with the reasoning. Disclose what you do not know, acknowledge the deficient images honestly, and stay within your competence. Do not overstate certainty; modesty in the statement is a strength. [10] [6]

Quality improvement (2). Remote peer review of documentation against a standard improves the completeness and quality of images over time, because structured feedback catches omissions and reinforces the protocol. The evidence supports embedding peer review as routine so documentation quality is maintained rather than allowed to drift. [2]
