1 · What the graph read from it

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.

2 · The registry

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

objectiveThe aim of the study was to assess the feasibility and potential of the Global Trigger Tool (GTT) for identifying adverse events (AEs) in different specialties in German hospitals.

methodsA total of 120 patient records were randomly selected from two surgical and one neurosurgery departments of three university hospitals in Germany for a period of 2 months per department between January and July 2017. The records were reviewed using an adaptation of the German version of the Institute for Healthcare Improvement GTT.

resultsThirty-nine records (32.5%) contained at least one AE. A total of 53 AEs were found in these 39 records. The incidences of AEs were 18.9% and 35.9% in the two surgical departments and 45.3% in neurosurgery. This corresponded to AE rates of 25.5 to 72.1 per 1000 patient-days and from 25.0 to 60.0 per 100 admissions across the three departments. A total of 71.7% of all identified AEs resulted in temporary harm (category E), 26.4% in temporary harm, requiring prolonged hospitalization (category F), and 1.9% in permanent patient harm. We also identified practical challenges, such as the necessary adaptation of the GTT relative to the respective department.

conclusionsThe application of the GTT is feasible and represents an effective instrument for quality measurement when adapted to the departmental specifics. The trigger detection with the GTT is a valuable addition for proactive analyses of high-risk processes.
