The impact of inter-hospital transfer on outcomes in lower gastrointestinal bleeding: a retrospective cohort analysis.
Article in BMC gastroenterology, 2025. 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
backgroundThis study investigates the role of interhospital transfer (IHT) in lower gastrointestinal bleeding (LGIB) management and its impact on patient outcomes, focusing on mortality rates, complication occurrences, procedural performance, and resource utilization in patients diagnosed with LGIB.
methodsThis retrospective cohort study used data from the National Inpatient Sample database from 2017 to 2020. It included adult patients diagnosed with LGIB, assessing the impact of IHT on outcomes such as mortality, complication rates, procedural performance, and resource utilization. Adjusted odds ratios (AOR) and adjusted mean differences (AMD) were used to evaluate these impacts.
resultsA total of 393,495 LGIB patients were analyzed, with 31,565 (8.02%) undergoing interhospital transfer. Transferred patients exhibited significantly higher inpatient mortality (AOR 1.96, P < 0.01). They also faced increased risks of acute kidney injury (AOR 1.32, P < 0.01), septic shock (AOR 2.11, P < 0.01), and intensive care unit admission (AOR: 2.61, P < 0.01). These patients were more likely to undergo interventional radiology-guided embolization (AOR 2.68, P < 0.01) and showed variations in colonoscopy procedures. Resource utilization was also higher among transferred patients, with an increased mean length of hospital stay by 4.37 days (P < 0.01) and higher hospitalization charges (mean difference $61,239, P < 0.01).
conclusionInterhospital transfer in LGIB patients is associated with increased mortality, greater resource utilization, and the need for more specialized procedural interventions. Enhanced clinical vigilance and tailored resource allocation for transferred LGIB patients are necessary. Future research should optimize care strategies for these high-risk patients.
