Clinical trial evidence supports early low-density lipoprotein cholesterol (LDL-C) goal achievement in patients with atherosclerotic cardiovascular disease (ASCVD), but real-world Asia is lacking. We investigated the effects of LDL-C on recurrent major events (MACEs) among very-high-risk ASCVD South Korea. included adult hospitalized (acute coronary syndrome [ACS], stable angina, ischemic stroke, transient attack, peripheral arterial disease, or asymptomatic artery disease) at a Korean...
Abstract Overcrowding of emergency departments is a global concern, leading to numerous negative consequences. This study aimed develop useful and inexpensive tool derived from electronic medical records that supports clinical decision-making can be easily utilized by department physicians. We presented machine learning models predicted the likelihood hospitalizations within 24 hours estimated waiting times. Moreover, we revealed enhanced performance these compared existing incorporating...
This mixed-methods study investigates the design and instructional practices of massive open online courses (MOOCs) instructors within learning environment to address cultural diversity learner personalization needs. Leveraging a grounded theory approach, researchers analyzed two rounds email interviews (n1= 25; n2=19) with MOOC education leaders about sensitivity in MOOCs. Those led formation 30-item questionnaire completed by 152 instructors. While many sample did not fully grasp complex...
Background Effective resource management in hospitals can improve the quality of medical services by reducing labor-intensive burdens on staff, decreasing inpatient waiting time, and securing optimal treatment time. The use hospital processes requires effective bed management; a stay that is longer than time hinders management. Therefore, predicting patient’s hospitalization period may support making judicious decisions regarding Objective First, this study aims to develop machine learning...
As warfarin has a narrow therapeutic window and obvious response variability among individuals, it is difficult to rapidly determine personalized dosage. Adverse drug events(ADE) resulting from overdose can be critical, so that typically physicians adjust the dosage through INR monitoring twice week when starting warfarin. Our study aimed develop machine learning (ML) models predicts discharge of as initial using clinical data derived electronic medical records within 2 days hospitalization....
Abstract Graph representation learning is a method for introducing how to effectively construct and learn patient embeddings using electronic medical records. Adapting the integration will support advance previous methods predict prognosis of patients in network models. This study aims address challenge implementing complex highly heterogeneous dataset, including following: (1) demonstrating build multi-attributed multi-relational graph model (2) applying downstream disease prediction task...
<title>Abstract</title> Predicting major adverse cardiovascular events (MACE) is crucial due to its high readmission rate and severe sequelae. Current risk scoring model of MACE are based on a few features patient status at single time point. We developed self-attention-based predict within 3 years from series data utilizing numerous in electronic medical records (EMRs). In addition, we demonstrated transfer learning for hospitals with insufficient through code mapping feature selection top...
Large language models (LLMs) have exhibited outstanding performance in natural processing tasks. However, these remain susceptible to adversarial attacks which slight input perturbations can lead harmful or misleading outputs. A gradient-based defensive suffix generation algorithm is designed bolster the robustness of LLMs. By appending carefully optimized suffixes prompts, mitigates influences while preserving models' utility. To enhance understanding, a novel total loss function...
Developing large-scale language models (LLMs) for health care requires fine-tuning with domain data suitable downstream tasks. However, LLMs medical can expose the training used during learning to adversarial attacks. This issue is particularly important as contain sensitive and identifiable patient data. The prompt-based attack approach was employed assess potential privacy breaches in LLMs. success rate of evaluated by categorizing 71 questions into three key metrics. To confirm exposure...
<title>Abstract</title> Background Predicting the length of stay in advance will not only benefit hospitals both clinically and financially but enable healthcare providers to better decision-making for improved quality care. More importantly, understanding severe patients who require general anesthesia is key enhancing health outcomes. Objective Here, we aim discover how machine learning can support resource allocation management resulting from prediction. Methods A retrospective cohort...
Although interest in predicting drug-drug interactions is growing, many predictions are not verified by real-world data. This study aimed to confirm whether predicted polypharmacy side effects using public data also occur from actual patients.
Background Predicting the bed occupancy rate (BOR) is essential for efficient hospital resource management, long-term budget planning, and patient care planning. Although macro-level BOR prediction entire crucial, predicting at a detailed level, such as specific wards rooms, more practical useful scheduling. Objective The aim of this study was to develop web-based support tool that allows administrators grasp each ward room according different time periods. Methods We trained time-series...
