The LLM demonstrated accuracy of 89% and was comparable with human physician classification in a 500-pair subsample.<\/p>\n\n\n\n<p><strong>Meaning<\/strong>&nbsp;&nbsp;These findings suggest that LLMs could accurately identify higher-acuity patient presentation when given pairs of presenting histories extracted from patients\u2019 first ED documentation.<a><\/a><\/p>\n\n\n\n<p>Abstract<\/p>\n\n\n\n<p><strong>Importance<\/strong>&nbsp;&nbsp;The introduction of large language models (LLMs), such as Generative Pre-trained Transformer 4 (GPT-4; OpenAI), has generated significant interest in health care, yet studies evaluating their performance in a clinical setting are lacking. Determination of clinical acuity, a measure of a patient\u2019s illness severity and level of required medical attention, is one of the foundational elements of medical reasoning in emergency medicine.<\/p>\n\n\n\n<p><strong>Objective<\/strong>&nbsp;&nbsp;To determine whether an LLM can accurately assess clinical acuity in the emergency department (ED).<\/p>\n\n\n\n<p><strong>Design, Setting, and Participants<\/strong>&nbsp;&nbsp;This cross-sectional study identified all adult ED visits from January 1, 2012, to January 17, 2023, at the University of California, San Francisco, with a documented Emergency Severity Index (ESI) acuity level (immediate, emergent, urgent, less urgent, or nonurgent) and with a corresponding ED physician note. A sample of 10\u202f000 pairs of ED visits with nonequivalent ESI scores, balanced for each of the 10 possible pairs of 5 ESI scores, was selected at random.<\/p>\n\n\n\n<p><strong>Exposure<\/strong>&nbsp;&nbsp;The potential of the LLM to classify acuity levels of patients in the ED based on the ESI across 10\u202f000 patient pairs. Using deidentified clinical text, the LLM was queried to identify the patient with a higher-acuity presentation within each pair based on the patients\u2019 clinical history. An earlier LLM was queried to allow comparison with this model.<\/p>\n\n\n\n<p><strong>Main Outcomes and Measures<\/strong>&nbsp;&nbsp;Accuracy score was calculated to evaluate the performance of both LLMs across the 10\u202f000-pair sample. A 500-pair subsample was manually classified by a physician reviewer to compare performance between the LLMs and human classification.<\/p>\n\n\n\n<p><strong>Results<\/strong>\u00a0\u00a0From a total of 251\u202f401 adult ED visits, a balanced sample of 10\u202f000 patient pairs was created wherein each pair comprised patients with disparate ESI acuity scores. Across this sample, the LLM correctly inferred the patient with higher acuity for 8940 of 10\u202f000 pairs (accuracy,\u20090.89 [95% CI, 0.89-0.90]). Performance of the comparator LLM (accuracy,\u20090.84 [95% CI, 0.83-0.84]) was below that of its successor. Among the 500-pair subsample that was also manually classified, LLM performance (accuracy,\u20090.88 [95% CI, 0.86-0.91]) was comparable with that of the physician reviewer (accuracy,\u20090.86 [95% CI, 0.83-0.89]).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240332f1_1714165663.50092.png?Expires=1724971462&amp;Signature=gIJwfj4kssn1hpNr4Mz~aYz2nGh7mUdZTGMv9kT70kGb75xz8nQHC5X0YeM~Azql9N6p9UDz-ZIfmf7kn1VhmgdRqrdWxWFmTRV8JpnW97n9SAn~zOf6WMdNMZgeBOdni2t1-t5CF~CtucyrOXKAEMJmo7wnpY-Fze-WZ1WX7OUlRu-IDEvzExwvHaIlYMOzssaOtZUcEmCbW7csipCbLln9tilVoRvS~9qzsM~yiE8j3aCb~zu3xLZPc-Uv90BJSAhjAOYA2p~XVhwAf~yEgDxJy7z23fNi1iFVUEgbKxh1Hbeurlh-zS82eJ0tuSyuNQbRF~vw0A7mT8pEt8v6jA__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240332f2_1714165663.52092.png?Expires=1724971462&amp;Signature=2-oU1bGbdyKAUN7f0IXrOFN7dSGc7pG6ptvC0S5qN4AHmlurhLLDXEWUK~c5~7ZhhNdtcXmrpSD8BNdnQE~xZ6USmWikrs0fHoLEszye5~YKTWlSrOcrVdEf9PmnYtQNpug24T2RCe5TpuxQX~ZoWsOzqSVImzYb0bK4A9tUnnDeh6qyKl7RIoSI9fmIO9TQVFc90M3lW2fh6hkHWm49SR2bb~TlGoOBjskU7k3yFL4i03MESui9nfqEMdURAXbrD6iMFSOfrTWmZJVUX20RIaztXEz4gzdgRad-b-9E8VWR34KrcLdfRfZ5trXmH282y8c0Yjdl7~QtfEoMo5MJ1A__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240332f3_1714165663.53592.png?Expires=1724971462&amp;Signature=tnCu-hjovJkn14Uk0QPmb-TUu7gg4mTykd21Ofwjn1RAItNBCU5DBsWwsNC~YyyHyzy~x7HgRWgn4YNXYV9zBO8LDPm-kLT9eVvER1-mIlVzRnxKs88xY6K7AY98-16O8yjVKnC1MWW~Bl8dFuWrhBJabExAuZlUlzccpEYA1~oa0u~UlK8tXMW100C8bA7AF0Zh1Wpyack0NMv4-L5MCRSDbHG4v-exiBiT-n7-28LFzGkgWVVHv75AERlmbgH5RoyLFIu2uCaNcLPwS7juq92cBIYP7sCiMuplHWozBgApbxe6alloFWc75V7GYP6ksLjRZg7TVzCm8hCISK0-Qw__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240332t1_1714165663.51091.png?Expires=1724971462&amp;Signature=EoZCEbU73HANvj3Sl6zpOLvC5xowvxjcK~SlbgHQBImdtOacFfkVDPMftXW8zKuQHs1qUU2cXk1fc1iV-GLxjxM6ruwGeoHV8M87C7jbNDeToipWS9NIPg7TdpbQsqEolVh-Xzjnt1eKOdv~fyDw48Xdt90oDmjCIeMZ2EWX37U~Qmu5dNSoGtNdQCbjO3DfRrRGbjtSsJvVEkFcU1FFdQVNdSuORY6ze-Wmpe-4PteXKqJ25Gmsc8MGmH2xsLbSbftAGlkY5XcbvtjhQiOGVtpKwj~kWGF~COTiqLl7DKEoubs2tc3lAX76~gaxswRNtj9kGUHqrfnATTaoxsoqqQ__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.jamanetwork.com\/ama\/content_public\/journal\/jamanetworkopen\/939364\/zoi240332t2_1714165663.52592.png?Expires=1724971462&amp;Signature=rxuHRft1v4hXtvJe5gvMo~iMC7Yxky4NL5HlBg9MFfxKSIDUd23987I7b-PupaxGN6zLj0Pn~M6on5rd8IfmPsUJgz19u3cyIHXrnwgS74G-GBrrS8KKFfolCInqfWXdZyDt4vfqxQgNxeh6tFZn5ERWSP4bZMjgeMHn-qP6bj7ETQLXRAOdPT6XRLMHnX1tmktHS54PhqqYWanWEUok88wRCNngB718l8ommlD0PO7JUUNz8br5YywiiPzH7ruziUhfJtZyNFFYksBYeH3bJsjjftCeWAXJ4aY2DiLcvq0J5DfibreNYFtXFYJ4GA8nRP1x~DINvinpTD2~aEPGLg__&amp;Key-Pair-Id=APKAIE5G5CRDK6RD3PGA\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Conclusions and Relevance<\/strong>&nbsp;&nbsp;In this cross-sectional study of 10\u202f000 pairs of ED visits, the LLM accurately identified the patient with higher acuity when given pairs of presenting histories extracted from patients\u2019 first ED documentation.
