Increasing clinicians' suspicion of ATTR amyloidosis using a retrospective algorithm.

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
backgroundThis study aimed to increase the index of suspicion for transthyretin amyloidosis (ATTR) among cardiologists leading to increased screening for amyloidosis.
methodsA retrospective algorithm was created to identify patients at risk for ATTR. A list of these patients and instructions on how to order amyloidosis testing were given to cardiologists, who then determined if further evaluation was warranted. The ordering trends of Technetium 99 m-Pyrophosphate (PYP) scans and the number of ordering physicians before and after this intervention were recorded across the entire practice.
resultsThe algorithm identified 349 potential high-risk patients of which only 23 eventually had PYP scans performed resulting in 2 equivocal and 1 positive results. Across the practice, over the 28 months before initiating this protocol, PYP scans were ordered for 22 patients of which 6 were equivocal or positive. Over the 23-month course of this project, 142 PYP scans were ordered of which 18 were equivocal or positive. The number of ordering providers increased from 7 prior to the protocol's implementation to 22 by the end of this project within 23 months. On change point analysis, PYP scan ordering increased after protocol initiation (regression coefficient 1.27 vs. 6.31, p < 0.001), as well as equivocal or positive PYP results (regression coefficient 0.38 vs. 0.52, p < 0.01).
conclusionThe results of this study suggest that using this algorithm, despite it not being independently predictive of ATTR, did result in our clinicians having a lower threshold for testing for ATTR. More clinicians ordered appropriate testing, and more positive tests were obtained.
