Post-prostatectomy rehospitalisation rates and risk factors in South Australian men with prostate cancer: evidence from linked data.
Article in International urology and nephrology, 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
purposeProstate cancer is a common malignancy in men, with radical prostatectomy (RP) being a major treatment option. This study investigates post-prostatectomy rehospitalisation rates and risk factors in a cohort of South Australian men who underwent RP from 2002 to 2021 (n = 5105).
methodsPost-prostatectomy rehospitalisation rates at 30 and 90 days were measured from hospital discharge data, with reasons determined from ICD-10 codes. Rates per 1000 person-time were estimated, accounting for the length of follow-up. Zero inflated negative binomial regression analyses were used to identify sociodemographic and clinical factors associated with the number of hospital encounters following RP.
resultsApproximately 13% of patients had at least one hospital visit within 90 days post-prostatectomy. Common reasons for early rehospitalisation (within 30 days) were urinary obstruction (3.2%), haematuria (2.6%), and urinary tract infection (2.5%). Older age (aged 75 + vs < 60: incidence rate ratio (IRR) 2.23, 95% CI: 1.88-2.64), highest comorbidity burden (3 + vs 0: IRR 2.33, 95% CI: 1.80-3.01), and high risk clinical characteristics (PSA > 20 vs < 10 ng/mL: IRR 1.67, 95% CI: 1.34-2.08 and Gleason score 9-10 vs < 7: IRR 1.39, 95% CI: 1.06-1.84) were associated with higher rehospitalisation rates. Conversely, men who were treated from 2016-2021 had 39% lower rehospitalisation rates (IRR 0.61, 95% CI: 0.53-0.71) compared with patients treated from 2002-2005.
conclusionThese findings highlight the importance of considering patient characteristics and tailoring post-surgical care plans to minimise rehospitalisation. The reduction in rehospitalisation over time may reflect advancements in surgical techniques, better patient selection or improved surgeon experience.
