pyDeid: an improved, fast, flexible, and generalizable rule-based approach for deidentification of free-text medical records.

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
Objectives: Deidentification of personally identifiable information in free-text clinical data is fundamental to making these data broadly available for research. However, there exist gaps in the deidentification landscape with regard to the functionality and flexibility of extant tools, as well as suboptimal tradeoffs between deidentification accuracy and speed. To address these gaps and tradeoffs, we develop a new Python-based deidentification software, pyDeid. Materials and Methods: pyDeid uses a combination of regular expression-based rules, fixed exclusion lists and inclusion lists to deidentify free-text data. Additional configurations of pyDeid include optional named entity recognition and custom name lists. We measure its deidentification performance and speed on 700 admission notes from a Canadian hospital, the publicly available n2c2 benchmark dataset of American discharge notes, as well as a synthetic dataset of artificial intelligence (AI) generated admission notes. We also compare its performance with the Physionet De-identification Software and the popular open-source Philter tool. Results: Different configurations of pyDeid outperformed other tools on various metrics, with a "best" accuracy value of 0.988, best precision of 0.889, best recall of 0.950, and best F1 score of 0.904. All configurations of pyDeid were significantly faster than Philter and Physionet De-identification Software, with the fastest deidentification speed of 0.48 s per note. Discussion and Conclusions: pyDeid allows the flexibility to prioritize between performance and speed, as well as precision and recall, while addressing some of the gaps in functionality left by other tools. pyDeid is also generalizable to domains outside of clinical data and can be further customized for specific contexts or for particular workflows.
