Common Reporting Errors

For Medical Students

What It Shows

The recurring reporting failures fall into five groups: the unanswered question, the missing negative, the unnamed convention, the promoted incidental finding, and the hedge. 5.20.1 covers structured reporting.

Each one appears across every structure in the knee rather than belonging to any single one. 5.20.2 covers reporting meniscal tears.

It matters because a report carrying any of the five reads as a normal report, which is why they persist. 5.1.6 covers imaging pitfalls.

How It Is Acquired

Check that the conclusion answers the question in the request. 5.1.3 covers choosing the correct investigation.

Check that the relevant negatives are present rather than assumed. 5.20.3 covers reporting ACL injuries.

Check that every measurement and grade names its convention. 5.20.5 covers reporting cartilage lesions.

Check that an incidental finding is described as incidental. 5.6.2 covers the meniscal signal grading.

Check that the conclusion commits rather than returning the decision. 4.1.6 covers the examination in the era of MRI.

What Normal Looks Like

A conclusion that uses the referrer's words and answers them. 5.1.3 covers choosing the correct investigation.

Negatives stated for the structures the question depended on. 5.20.4 covers reporting MCL injuries.

Conventions named beside every number. 5.16.4 covers the TT-TG measurement.

Incidental findings labelled as such and kept out of the answer. 5.14.1 covers synovitis.

A limitations sentence saying what the study could not assess. 5.5.1 covers the standard protocol.

What Abnormal Looks Like

A described scan with no answer in it. 5.1.2 covers clinical examination versus imaging.

A findings list where a structure's absence could mean normal or unexamined. 5.5.9 covers the ligaments.

A grade or a measurement with no system behind it. 5.20.6 covers reporting osteoarthritis.

Degenerative change promoted into the explanation for the symptoms. 5.20.2 covers reporting meniscal tears.

A conclusion offering possibilities in the order they occurred to the reader. 5.1.6 covers imaging pitfalls.

MRCS Level

How It Is Acquired

In a viva the expected answer groups the errors by cause rather than listing them.

The expected points are the unanswered question, the missing negative, the unnamed convention, the promoted incidental finding, and the hedge.

Say that the quality of the request limits the quality of the report, so the error sometimes starts with the referrer. 5.1.3 covers choosing the correct investigation.

Say that a copied report carries a stale finding forward. 5.20.7 covers reporting the post-operative knee.

Say that the hedge is the failure that costs a clinic appointment. 4.1.6 covers the examination in the era of MRI.

What Abnormal Looks Like

The reasoning expected is that each failure has a cause rather than being carelessness: a vague request, a template without negatives, several competing conventions, a knee full of age related change, and a reader who will be reviewed on what they said. 5.21.5 covers the osteoarthritis imaging literature.

The promoted incidental finding carries the largest clinical cost, because it starts a pathway. 5.6.2 covers the meniscal signal grading.

The hedge is rational for the reporter and expensive for the patient, which is why it needs naming rather than blaming. 5.1.7 covers evidence-based imaging.

The unnamed convention is the cheapest of the five to fix and the one most often left. 5.20.5 covers reporting cartilage lesions.

How Good It Is

Naming the failure patterns is the best available check on a report and is no substitute for reading the images.

Its best contribution is catching the four structural failures, which are visible in the text itself. 5.20.1 covers structured reporting.

It is limited because it cannot catch a confidently wrong finding, which looks identical to a correct one in the report. 5.1.6 covers imaging pitfalls.

No figures appear for accuracy on this page, under decision 028, and no error rates appear either: those are published quantities from particular audits and this environment cannot check them.

FRCS Level

How Good It Is

At decision level the surgeon is the last check on the report and should read it for these five before reading the images. 5.20.1 covers structured reporting.

A report with no negatives cannot be used to plan, whatever it says it found. 5.20.3 covers reporting ACL injuries.

A report with an unnamed convention should go back rather than be interpreted. 5.16.4 covers the TT-TG measurement.

A promoted incidental finding has usually reached the patient already, which changes the consultation rather than the plan. 5.1.2 covers clinical examination versus imaging.

Disagreeing with a report is a clinical decision and belongs in the notes with its reasons. 4.1.8 covers the examination documentation.

Where It Misleads

The commonest error about errors is treating them as individual lapses rather than as properties of the system that produced them. 5.1.7 covers evidence-based imaging.

A department's local phrasing is read as a national convention. 5.21.1 covers the meniscal imaging literature.

A second opinion that repeats the first report is counted as agreement when it may be anchoring. 5.20.1 covers structured reporting.

A report's confidence is read as its accuracy. 5.1.6 covers imaging pitfalls.

The absence of a hedge is read as certainty when the reporter simply writes differently. 4.1.6 covers the examination in the era of MRI.

Fellowship Level

Where It Misleads

At fellowship level most studies you see were reported elsewhere, so the five failures arrive as inherited constraints rather than as correctable ones. 5.20.7 covers reporting the post-operative knee.

Re-reporting changes a patient's pathway and needs recording as a decision with its reasons. 4.1.8 covers the examination documentation.

A tertiary practice sees the reports that were wrong, which makes the base rate invisible from where you sit. 5.1.7 covers evidence-based imaging.

Automated reporting removes the hedge and the missing negative while keeping the confidently wrong finding. 5.18.8 covers artificial intelligence in imaging.

A model trained on reports learns the conventions of the departments that wrote them, the local phrasing included. 5.21.6 covers the artificial intelligence literature.

The honest position is that the four structural failures are fixable by template and the fifth, a confident wrong finding, is not fixable by any of this. 5.20.1 covers structured reporting.
