Factors associated with cancellation of arteriovenous access creations.
Article in Journal of vascular surgery, 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
objectiveCancellation of arteriovenous (AV) access creation delays establishing permanent hemodialysis (HD) access, potentially affecting patient outcomes and health care efficiency. Our goal was to assess the rate of AV access cancellations and identify contributing factors in a safety net hospital.
methodsAll AV access creations at a single academic medical center (2018-2024) were retrospectively reviewed. Reasons for outpatient and inpatient AV access creation cancellations on the planned day and week scheduled were analyzed using chart review. A multivariable analysis was performed to assess for predictors of same-day outpatient cancellations.
resultsThere were 584 patients who were scheduled for an AV access creation during the study period. Of these, 17.7% had same-day cancellations, and 7.7% had week-before cancellations. The most common reasons for same-day cancellation were acute illness (21.4%), chronic kidney disease-related complications (21.4%), logistical issues (11.7%), and inadequate preoperative preparation (13.6%). The most common reasons for cancellations 1 week before scheduled operation were patient choice (22.7%) acute illness (20.5%), inadequate preoperative preparation (20.5), and logistical issues (11.4%). On multivariable analysis, same-day outpatient cancellations were significantly associated with an afternoon case start time (odds ratio, 3.09; 95% confidence interval, 0.75-2.37; P < .001). The median time to AV access creation following a cancellation was 32 days. However, among same-day cancellations, 14.3% of patients did not proceed with permanent HD access within 6 months, and 7% required an interval tunneled dialysis catheter. Among week-before cancellations, 16.7% did not proceed with permanent HD access within 6 months, and 4.7% required an interval tunneled dialysis catheter.
conclusionsCancellations of AV access creations affected one-quarter of scheduled cases, with several patients not proceeding with permanent HD access by 6 months. Acute illness, poor control of chronic kidney disease-related complications, and logistical factors were among the most common reasons for cancellations, highlighting potential areas for targeted improvement. Targeted efforts such as scheduling optimization and improved preoperative preparation may help reduce surgical cancellations and prevent unnecessary catheter placements. These interventions are also likely to enhance the overall quality of HD care for patients.
