Outcomes after peripheral artery disease intervention among Medicare-Medicaid dual-eligible patients compared with the general medicare population in the Vascular Quality Initiative registry.
Article in BMJ surgery, interventions, & health technologies, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
objectiveTo determine whether patients from the Vascular Quality Initiative (VQI) registry who are Medicare-Medicaid dual-eligible have outcomes after surgical intervention with medical devices such as stents for peripheral artery disease comparable to the outcomes of those eligible for Medicare alone.
methodsThe study cohort included fee-for-service Medicare beneficiaries from 2010 to 2015 who underwent peripheral vascular intervention as determined by the VQI. We performed propensity matching between the dual-eligible and non-dual-eligible cohorts. Postintervention use, including imaging, amputation and death, was determined using Medicare claims data.
resultsRates of major amputation were higher among dual-eligible patients (13.0% vs 10.5%, p<0.001), while time to amputation by disease severity was similar (p=0.443). For patients with more advanced disease (critical limb ischaemia (CLI) vs claudication), dual-eligible patients have significantly faster times to any amputation and death (p<0.001). For of postoperative imaging, 48.4% of dual-eligible patients receive at least one postoperative image, while the percentage for non-dual-eligible patients is 47.2% (p=0.187).
conclusionsPatients with mild forms of peripheral artery disease (PAD), such as claudication, demonstrated similar outcomes regardless of dual-eligibility status. However, those with severe PAD, such as CLI, who were also dual-eligible had both inferior overall survival and amputation-free survival. Minimal differences were observed in process-driven aspects of care between dual-eligible and non-dual-eligible patients, including postoperative imaging. These findings indicate that despite receiving similar care, dual-eligible patients with severe PAD have inferior long-term outcomes, suggesting the Medicaid safety net is not timely enough to benefit from long-term outcomes for these patients.
