    Background: Artificial intelligence (AI) has been widely adopted to predict the occurrence of latent shock in critical ills in the intensive care unit (ICU). However, usefulness of ICU-based model for predict latent shock risk in emergency department (ED) remains unclear. This study was aimed to develop an AI model to predict the latent shock risk in patients admitted to ED. Methods: Multiple regression analysis was used to compare the difference between Medical Information Mart for Intensive Care (MIMIC)-IV-ICU and MIMIC-IV-ED data sets. An adult noninvasive model was constructed based on MIMIC-IV-ICU v3.0 database, and externally validated in populations admitted to ED. Its efficiency was compared with the noninvasive systolic blood pressure (nSBP) and shock index. Results: A total of 50,636 patients of MIMIC-IV-ICU database was used for developing the model, and a total of 2,142 patients of the Philips IntelliSpace Critical Care and Anesthesia (ICCA)-ED and 425,087 patients of MIMIC-IV-ED was used for external validation. The modeling and validation data revealed similar non-invasive feature distributions. Multiple regression analysis of MIMIC-IV-ICU and MIMIC-IV-ED datasets showed mostly similar characteristics. Area under the receiver operating characteristic curve (AUROC) of noninvasive model on 10 minutes before the intervention was 0.90 (95% CI 0.84–0.96), and the diagnose accordance rate(DAR) is above 80%. More than 80% of latent shock patients could be identified more than 70 minutes earlier. Noninvasive model performed better than shock index and nSBP. Conclusion: The adult noninvasive model can effectively predict the latent shock occurrence in ED, which is better than shock index and nSBP.
