Suspected Pediatric Appendicitis Management in the Emergency Department: A Prospective Observational Study in an Australian Pediatric Emergency Department.
Observational study in Pediatric emergency care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveAbdominal pain is a common pediatric presentation in the emergency department (ED), and acute appendicitis (AA) is the most common surgical diagnosis. This study describes the management of suspected AA in a tertiary Australian pediatric ED.
methodsA single-center prospective observational study was performed between November 2022 and May 2023. Children aged 5 to 15 years presenting to the ED with acute abdominal pain and clinician suspicion of AA were included. Clinical gestalt was measured using a 5-point Likert Scale before and after blood tests. Diagnosis of AA was confirmed on histopathology, and non-AA was confirmed with follow-up at 30 to 60 days.
resultsThe study enrolled 481 children; AA was diagnosed in 146 (30.6%). Patients with AA were older (11.1 vs. 10.0 y) and more likely to be male (69.2% vs. 48.1%) compared with those without AA. Blood tests were performed in 449 (93.3%) children, with higher rates in AA cases (100% vs. 90.4%). Gestalt improved with blood test results, with overall diagnostic accuracy increasing from 65.9% pre-blood tests to 88.5% post-blood tests. Ultrasound (US) was performed in 361 (75.1%) children with a diagnostic accuracy of 90.6% and was frequently used even in patients deemed low-risk post-blood tests (65.7%). One hundred and fifty (31.2%) of suspected AA cases underwent surgery, with 3 negative appendectomies and 1 ovarian cystectomy without appendectomy. Median (IQR) hospital length of stay was significantly longer for AA cases than non-AA cases [50.8 (35.3 to 95.0) h vs. 7.1 (4.6 to 16.8) h].
conclusionsThis study reviews the management and outcomes of suspected AA in a high-volume Australian ED. It shows the importance of blood tests in improving diagnostic accuracy of clinician gestalt and highlights the potential overuse of US in low-risk patients. Future research should explore a more structured diagnostic approach to increase diagnostic accuracy, optimize resource utilization, and improve patient outcomes.
