This study developed a decision support tool for hepatic surgery risk assessment. The tool uses a research database to estimate patient risk, aiding surgeons in surgical planning and patient consultation.

Area of Science:

  • Surgical Oncology
  • Medical Informatics
  • Health Services Research

Background:

  • Hepatic surgery involves complex procedures with significant patient risks.
  • A high-granular, web-based research database was created to document variables for evaluating surgical techniques.

Purpose of the Study:

  • To integrate a decision support system into clinical practice for hepatic surgery.
  • To provide surgeons and patients with preoperative risk assessment for surgical procedures.

Main Methods:

  • Developed an interactive decision support component for a research database.
  • Utilized five established predictors and a similarity search to estimate individual patient risk.
  • Visualized risk analysis using Kaplan-Meier plots.

Main Results:

  • Evaluated the decision support component using data from 165 hepatocellular carcinoma patients (1996-2000).
  • Similarity search identified distinct patient groups, highlighting variations in risk profiles.
  • Risk estimations aligned with observed survival data, though caution is advised due to limited reference cases.

Conclusions:

  • Clinical integration is crucial for the decision support system's success.
  • A transparent and reliable knowledge base is essential for user trust.
  • Ongoing user feedback is vital for system improvement and validation.
