Facility-Level Variation Underlying Low Inferior Vena Cava Filter Retrieval in the United States.
Article in Journal of the American College of Radiology : JACR, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTimely retrieval of inferior vena cava (IVC) filters is recommended to reduce complications and optimize outcomes. This study aims to quantify facility-level variation in risk-adjusted IVC filter retrieval across US hospitals and to identify patient- and hospital-level factors associated with nonretrieval.
methodsMedicare beneficiaries undergoing IVC filter implantation were identified in the 100% claims files for years 2016 to 2020. Facility-level variation in device retrieval was quantified using Bayesian hospital profiling. Patient- and hospital-level factors associated with nonretrieval were assessed using logistic regression, adjusting for diagnostic indication, comorbidities, and implantation year.
resultsIVC filters were implanted in 119,613 Medicare beneficiaries across 2,485 facilities. Retrieval rates were low: median 6.2% within 3 months and 14.8% within 1 year. Excluding deaths within 3 months (30.2%), retrieval ranged from 0% to 100% across facilities. Among high-volume hospitals (top 25th percentile, implanting ≥13 filters per year), 1-year risk-adjusted retrieval ranged from 0% to 74.5%, mean 20% ± 14.2% (positive skew 0.95). Patient factors associated with IVC filter nonretrieval included age > 80 years (odds ratio 2.98, 95% confidence interval [2.73-3.24]), Black race (1.62, [1.51-1.72]), and Hispanic ethnicity (1.45, [1.16-1.80]). Among hospital factors, nonteaching (1.45 [1.37-1.53]), small bed size (1.37 [1.24-1.50]), and safety-net (1.42 [1.34-1.50]) facilities were strongly associated with IVC filter nonretrieval. DISCUSSION: High mortality within 3 months of IVC filter implantation suggests opportunity to improve patient selection and, potentially, device type choice. There is large facility-level variance underlying low aggregate IVC filter retrieval nationally; a focus on standardizing device surveillance and identifying best practices from high-performing facilities is warranted.
