Turnover Time in Neuroangiography Suites: Comparison Between Cases Performed at an Ambulatory Neurosurgery Center Versus a Tertiary Hospital.
Article in Stroke (Hoboken, N.J.), 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
backgroundEfficient turnover time (TOT) and adherence to first-start time (FST) in operating and angiography suites are critical for optimizing workflow, reducing costs, and maximizing patient satisfaction. Hospitals face challenges in maintaining these metrics due to operational constraints and unexpected emergent cases. Our goal was to compare TOT, FST, and total admission time for elective cases performed in angiography suites at an ambulatory neurosurgery center (ANSC) versus a tertiary hospital (TH).
methodsWe conducted a retrospective analysis of data for patients who underwent elective diagnostic or interventional neuroendovascular procedures at the TH or ANSC from January 2024 through October 2024. TOT was defined as the time between the end of one case and the start of the next. FST was defined as the time the first patient of the day entered the suite. In addition, digital subtraction angiography cases at the ANSC were age- and indication-matched with same-day discharge digital subtraction angiography cases from the TH to compare total admission, preprocedural wait, procedural, and postprocedural times (minutes).
resultsA total of 1174 procedures were performed at the TH and 155 at the ANSC. Mean TOT was longer at the TH (30.6 ± 25 minutes) than the ANSC (12 ± 2.8 minutes;
conclusionsData for ANSC procedures demonstrated significantly improved operational efficiency compared with TH procedures, with shorter TOT, earlier FST, and reduced total admission durations for elective digital subtraction angiography cases. These findings support the growing role of ANSCs in optimizing resource utilization and efficiency while maintaining high-quality patient care.
