Appendicitis-II: Diagnostic Studies and Management

100
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

科学领域:

  • 腹腔外科手术的结果
  • 在医疗保健中的预测建模.
  • 机器学习应用程序 机器学习应用程序

背景情况:

  • 减肥手术对于减肥是有效的,但与昂贵的再入院有关.
  • 预测术后再入院对于改善患者的治疗结果和减少医疗保健费用至关重要.

研究的目的:

  • 开发和比较机器学习 (ML) 算法,用于预测腹腔外科手术后30天的再入院.
  • 对传统的物流回归来评估ML模型的性能.

主要方法:

  • 利用了来自代谢和腹部外科认证和质量改进计划 (MBSAQIP) 数据库 (2016-2020) 的数据.
  • 使用随机森林 (RF),梯度增强 (XGB) 和深度神经网络 (NN) 分析患者变量.
  • 使用接收器操作特征曲线 (AUROC) 下面的面积与后勤回归 (LR) 的比较预测准确性.

主要成果:

  • 包括863,348名患者;4.52%的人重新入院.
  • 在XGB和RF模型中,AUROC得分为0.785,远高于LR的0.62 (P<.001).
  • 最好的模型 (XGB) 显示了73.81%的灵敏度和70%的特异性.

结论:

  • 机器学习模型比后勤回归提供了相当大的改进,用于预测减肥手术再录取.
  • 经过验证的ML模型可以识别适合早出院或需要专注的出院后支持的患者.
