Observation management of pulmonary embolism and agreement with claims-based and clinical risk stratification criteria in United States patients: a retrospective analysis.
Article in BMC pulmonary medicine, 2017. 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
backgroundGuidelines suggest observation stays are appropriate for pulmonary embolism (PE) patients at low-risk for early mortality. We sought to assess agreement between United States (US) observation management of PE and claims-based and clinical risk stratification criteria.
methodsUsing US Premier data from 11/2012 to 3/2015, we identified adult observation stay patients with a primary diagnosis of PE, ≥1 PE diagnostic test claim and evidence of PE treatment. The proportion of patients at high-risk was assessed using the In-hospital Mortality for PulmonAry embolism using Claims daTa (IMPACT) equation and high-risk characteristics (age > 80 years, heart failure, chronic lung disease, renal or liver disease, high-risk for bleeding, cancer or need for thrombolysis/embolectomy).
resultsWe identified 1633 PE patients managed through an observation stay. Despite their observation status, IMPACT classified 46.4% as high-risk for early mortality and 33.3% had ≥1 high-risk characteristic. Co-morbid heart failure, renal or liver disease, high-risk for major bleeding, cancer and hemodynamic instability were low (each <4.5%), but 7.8% were >80 years-of-age and 19.4% had chronic lung disease.
conclusionMany PE patients selected for management in observation stay units appeared to have clinical characteristics suggestive of higher-risk for mortality based upon published claims-based and clinical risk stratification criteria.
