Establishing a rapid-response multidisciplinary service for thrombotic microangiopathies using a model of improvement framework: perspectives from a Brazilian quaternary hospital.
Article in Frontiers in medicine, 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
Thrombotic microangiopathies (TMA) require prompt identification and coordinated treatment because they are associated with substantial morbidity, irreversible target-organ injury, and mortality. Yet fragmented diagnostic and care pathways often delay diagnosis and lead to poorer outcomes. This Perspective article describes the design and implementation of a TMA Center of Excellence at a Brazilian quaternary hospital. This initiative aimed to design and implement a rapid-response, multidisciplinary TMA service to shorten diagnostic and treatment delays, standardize diagnosis-specific care, and establish prospective measures to evaluate clinical and operational performance. Rather than reporting outcomes, we highlight design choices, stewardship safeguards for high-cost therapies, and practical implementation enablers. Multidisciplinary teams designed and tested diagnostic and therapeutic workflows using iterative Plan-Do-Study-Act cycles. Care pathways tailored to specific patient populations were embedded into the electronic medical record (EMR). EMR integration enabled real-time alerts triggered by key laboratory results, while embedded tools, such as the PLASMIC score (platelet count, hemolysis, no active cancer, no history of solid-organ or stem-cell transplant, mean corpuscular volume, international normalized ratio, and creatinine) and therapy-specific prescription menus, guided clinical decisions. A structured indicator framework was developed to prospectively monitor time to diagnosis, adherence to clinical pathways, length of stay, and intensive care utilization. Interdisciplinary collaboration facilitated alignment across emergency, radiology, laboratory, nephrology, and hematology services. This quality improvement strategy supports the feasibility of implementing a comprehensive, multidisciplinary model for TMA management and offers a transferable blueprint that middle-income health systems can adapt.
