Utilizing electronic health records (EHRs) permits analysis of care approaches and disease outcomes at a lower cost than prospective research. However, reviewing EHR manually is time intensive. We aimed to compare refractory status epilepticus (rSE) cases identified by human EHR review with a natural language processing (NLP)\u2010assisted rSE screen followed by a manual review.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We used the NLP screening tool Document Review Tool (DrT) to generate regular expressions, trained a bag\u2010of\u2010words NLP classifier on EHRs from 2017 to 2019, and then tested our algorithm on data from February to December 2012. We compared results from manual review to NLP\u2010assisted search followed by manual review.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Our algorithm identified 1528 notes in the test set. After removing notes pertaining to the same event by DrT, the user reviewed a total number of 400 notes to find patients with rSE. Within these 400 notes, we identified 31 rSE cases, including 12 new cases not found in manual review, and 19 of the 20 previously identified cases. The NLP\u2010assisted model found 31 of 32 cases, with a sensitivity of 96.88% (95% CI =\u200982%\u201399.84%), whereas manual review identified 20 of 32 cases, with a sensitivity of 62.5% (95% CI\u2009=\u200943.75%\u201378.34%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Significance<\/jats:title><jats:p>DrT provided a highly sensitive model compared to human review and an increase in patient identification through EHRs. The use of DrT is a suitable application of NLP for identifying patients with a history of recent rSE, which ultimately contributes to the implementation of monitoring techniques and treatments in near real time.<\/jats:p><\/jats:sec>","DOI":"10.1111\/epi.17789","type":"journal-article","created":{"date-parts":[[2023,10,7]],"date-time":"2023-10-07T08:33:29Z","timestamp":1696667609000},"page":"3227-3237","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Natural
