A Cost Analysis of All-Staff Emails in an Australian Hospital Network (CASH Study).
Article in ANZ journal of surgery, 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
backgroundWritten communication has changed dramatically in the computer era. Email use has exploded in the last three decades, from the inter-individual level through to mass dissemination. In the workplace, it has become the default mode of communication despite very limited critical appraisal. Specifically in the healthcare setting, its utility as a communication strategy for broadcasting information has barely been examined. The aim of this study was to quantify the use of all-staff emails (ASE) across a public hospital and its umbrella Hospital and Health Service (HHS).
methodAn audit of one year's ASE was performed to determine the number, word count and readability using validated metrics. The median was used as a reference text. Seventy five randomly selected volunteers from the five occupation groups in the health service were timed whilst reading the reference text to enable an estimate of time and financial cost.
resultsFive hundred and six ASE were identified, with a median length of 622 words (95% CI 570 to 694). The median Flesch-Kincaid (FK) Grade score was 8.9 (95% CI 8.8 to 9.1). The calculated predicted salary costs if all staff read all ASE in 1 year were AU$6 116 386.47 (range AU$3 441 365.32 to AU$13 424 704.98) at the hospital level and AU$14 555 209.62 (range AU$8 258 984.03 to AU$31 778 109.75) at the HHS level.
conclusionsA modest reduction in annual ASE burden could result in considerable savings for hospitals and hospital health services, which could be reinvested into patient care, procedures and staff wellbeing. Further research would improve the limited understanding of the impacts of ASE and build an evidence base for how to optimise their use.
