{"title":"Author's Reply: A Machine Learning Model for Predicting Short-Term Outcomes After Rapid Response System Activation","authors":"Takaki Naito, Shigeki Fujitani","doi":"10.1002/ams2.70143","DOIUrl":"https://doi.org/10.1002/ams2.70143","url":null,"abstract":"<p>We thank the authors for their insightful comments regarding our article, “A machine learning model for predicting short-term outcomes after rapid response system activation.” We appreciate the opportunity to address their concerns.</p><p>We agree that longitudinal trends can enhance predictive performance. However, as our retrospective study utilized an existing multicenter registry, temporal granularity was limited. We intentionally focused on whether data available at the exact moment of RRS activation could predict outcomes. This approach aims to support bedside decisions in environments where real-time, time-series analysis is technically challenging. Our team has previously reported on the importance of temporal trajectories [<span>1</span>], and we consider their integration a priority for future models.</p><p>We fully agree that model interpretability is a critical factor for successful implementation in clinical practice. Our feature importance analysis confirmed that the key predictors aligned with clinical intuition. We recognize that a key future task is to optimize the model to provide specific rationales for individual predictions to enhance clinician trust. Furthermore, machine learning models may detect subtle features that are not yet apparent to humans, potentially allowing for the identification of clinical deterioration at a very early stage [<span>2</span>]. Therefore, beyond making models more interpretable, it is indispensable for future clinical implementation to foster “artificial intelligence (AI) literacy” among clinicians, enabling them to deeply understand and complementarily utilize the characteristics of AI-detected signs.</p><p>As acknowledged in our limitations section, the scope of this study was constrained by its specific sample size and registry. The concern that a model trained in a single country may not be directly applicable to other healthcare environments as a universal model is well-founded. Nonetheless, it serves as a crucial proof-of-concept for integrating AI into the RRS context. Furthermore, we propose an alternative to universal models: in an era of accessible machine learning tools, individual facilities can fit customized models to their unique clinical environments. Regardless of the developmental approach, we fully agree that prospective validation to evaluate actual clinical impact is the most critical next step.</p><p>The insights provided are invaluable for the evolution of our research. While this study represents an initial step with inherent limitations, we remain committed to refining these models through longitudinal data integration, explainable AI, and prospective validation.</p><p>The authors have nothing to report.</p><p>S.F. reported receipt of grants from Nihon Kohden outside the submitted work.
