研究目的: |
为普通病房患者的风险评估和管理提供一种基于机器学习的新颖、有效、可解释的方法,有助于提高患者的安全性和生存率,降低医疗资源的浪费和成本。我们希望通过建立一个基于随机森林分类的预测模型,能够准确地判断普通病房患者是否需要转入ICU,并且能够识别出影响风险的重要变量和交互效应。我们还希望通过解释模型的预测机制和逻辑,能够为临床决策提供有用的指导,并为未来的研究提供新的思路和方向。 |

|
Objectives of Study: |
Provide a novel, effective, and interpretable machine learning-based method for risk assessment and management of general ward patients, which helps improve patient safety and survival rates, and reduce waste and costs of medical resources. We aim to establish a predictive model based on random forest classification that can accurately determine whether general ward patients need to be transferred to the ICU, and identify important variables and interaction effects that influence risks. We also hope that by explaining the predictive mechanisms and logic of the model, we can offer useful guidance for clinical decision-making and provide new ideas and directions for future research. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据收集:从医院的电子病历系统中提取所有入选患者的基本信息、生理参数、主要诊断、ICU类别、APACHE II评分等数据,并计算每位患者入院后24小时内最高MEWS评分作为自变量之一; 数据管理:完成所有入选患者的数据提取和录入,形成完整的数据集;检查数据的完整性和准确性,使用数据质量控制工具进行数据审核; |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection: Extract basic information, physiological parameters, primary diagnoses, ICU categories, APACHE II scores, and other data of all selected patients from the hospital's electronic medical record system, and calculate the highest MEWS score within 24 hours of each patient's admission as one of the independent variables; Data management: Complete the data extraction and entry for all selected patients to form a complete dataset; check the integrity and accuracy of the data, and use data quality ; |
