Continuous monitoring of neonatal care activities remains challenging because routine caregiving procedures are rarely documented in electronic medical records, despite their potential impact on neonatal physiological stability. This study introduces the NEO TINY System (NTS), an integrated AI-enabled monitoring platform capable of synchronizing bedside video with physiological data collected from NICU medical devices.
The proposed framework combines an Inception-v3 Convolutional Neural Network (CNN) with a Long Short-Term Memory (LSTM) network to automatically recognize neonatal caregiving activities from video sequences while simultaneously evaluating associated changes in heart rate and oxygen saturation. The study analyzed video and physiological recordings collected from 10 neonates across two Level III NICUs, capturing 167 patting events, 64 diaper changes, and 108 tube feeding procedures.
The deep learning system achieved 95% training accuracy and 85% validation accuracy while automatically generating structured documentation of neonatal care activities that are typically absent from electronic medical records. The study also demonstrated statistically significant physiological responses associated with routine caregiving activities, highlighting the potential of AI-assisted monitoring to improve neonatal documentation, quantify stress associated with caregiving, and support future intelligent clinical decision systems in NICUs.
Premature infants admitted to Neonatal Intensive Care Units (NICUs) experience numerous routine caregiving procedures every day, many of which contribute to cumulative physiological stress that may adversely affect neurodevelopment. Existing approaches for measuring neonatal stress rely on manual documentation using the Neonatal Infant Stressor Scale (NISS), making continuous monitoring impractical in busy clinical environments.
This study developed a multimodal deep learning system that analyzes bedside video recordings together with synchronized physiological signals to automatically detect neonatal care manipulation activities, quantify their duration and frequency, estimate immediate physiological responses, and calculate stress exposure. The framework was trained and evaluated using 289 hours of synchronized video and physiological recordings collected during 330 clinical sessions from 27 neonates across two NICUs. Using advanced computer vision models and temporal activity localization techniques, the system achieved activity quantification statistically equivalent to expert human annotation within clinically acceptable error margins while accurately identifying activities associated with significant physiological changes.
The proposed framework represents an important step toward continuous, objective, AI-powered neonatal stress monitoring capable of supporting clinicians with standardized documentation, automated Neonatal Infant Stressor Scale (NISS) estimation, and real-time decision support in intensive care environments.
Accurate prediction of neonatal mortality remains one of the most challenging problems in critical care. This study developed a High Definition Phenotype (HDP) framework that integrates electronic medical records, laboratory results, bedside physiological monitoring, medications, nutrition, and derived physiological features into a unified time-series representation of each patient.
Clinical data from 1,546 neonatal admissions across eight Level III NICUs were collected, with 757 patients containing complete fixed, intermittent, and continuous datasets for model development. Two predictive approaches—a Logistic Regression Model (LRM) and a Long Short-Term Memory (LSTM) deep learning model—were developed and compared with established neonatal severity scores including CRIB, CRIB-II, SNAP-II, and SNAPPE-II.
Both AI models consistently outperformed traditional severity scores, with the LSTM achieving an AUC of up to 0.96, while also providing continuously updated mortality risk predictions throughout hospitalization. The framework demonstrates the potential of integrating multimodal clinical data into real-time bedside decision support systems capable of detecting patient deterioration earlier than conventional approaches.
Length of stay (LOS) is an important indicator of neonatal outcomes, healthcare resource utilization, and hospital costs. This study developed an artificial intelligence–based prediction model that estimates NICU length of stay using routinely collected electronic medical record data. Unlike previous approaches, the model incorporated antenatal and perinatal characteristics, deviations from ASPEN nutrition guidelines, deviations from NeoFax medication recommendations, and major neonatal clinical diagnoses. Data from 836 neonatal admissions across two tertiary NICUs were used to develop gestation-specific predictive models and validated using an independent cohort of 211 patients. The resulting bedside interface enables clinicians to visualize patient-specific risk factors contributing to prolonged hospitalization, supporting family counseling, clinical decision-making, and operational planning while demonstrating the feasibility of real-time AI-assisted predictive analytics within neonatal intensive care.
Artificial intelligence (AI) and machine learning (ML) are rapidly transforming neonatal intensive care by enabling predictive analytics from large volumes of clinical data. This systematic review evaluated 68 published studies examining AI and ML applications for predicting neonatal morbidities, mortality, and length of stay in NICUs. The review analyzed prediction models, data sources, machine learning techniques, and performance metrics while identifying current limitations and future opportunities. The authors propose that integrating multimodal data—including electronic medical records, physiologic monitoring, medical imaging, laboratory results, and environmental sensing—can enable next-generation clinical decision support systems that improve neonatal outcomes through personalized, real-time predictive analytics.
Premature infants require individualized nutritional management to support optimal growth and neurodevelopment, yet adherence to neonatal nutrition guidelines remains challenging in busy intensive care units.
This research introduces the Nutrition Recommendation Ontology (NRO), an ontology- and rule-based clinical decision support system that integrates electronic medical record data with standardized neonatal nutrition guidelines. The system models neonatal clinical information using semantic technologies, knowledge graphs, and logical reasoning to generate personalized recommendations for enteral and parenteral nutrition while automatically identifying deviations from established guidelines.
The framework was developed using retrospective data from 601 NICU patients representing 8,460 patient-days of clinical care. The ontology consists of 121 classes, 366 axioms, and 157 semantic rules, enabling automated reasoning based on gestational age, day of life, clinical conditions, risk factors, and neonatal morbidities.
Validation by an expert panel of neonatologists demonstrated 98% agreement between the system-generated recommendations and expert clinical decisions, highlighting the promise of semantic artificial intelligence for improving nutritional management and supporting evidence-based decision making in neonatal intensive care units.
