Pad-Line

Pad-Line is a lightweight clinical timeline visualization tool for oncology pharmacotherapy management.
It integrates adverse events (AEs) and clinical actions (e.g., hold / dose reduction) on a single patient-centric time axis to reduce cognitive load during case review and conferences.

Scope: Visualization & workflow support
Not a clinical decision recommendation system.

Background

In daily clinical practice, relevant information is often fragmented across free-text notes and isolated time points.
This makes it time-consuming to reconstruct:

• when an AE started and how long it persisted,
• when an action (hold / dose reduction / restart) occurred,
• how multiple events overlapped over time.

Pad-Line focuses on N=1 case understanding (safe management and efficient discussion).
If structured data accumulates naturally, the same format can be reused for multi-patient comparison (swimmer plot) and further analysis.

Key Features

• Swimmer / Swimlane toggle
  • Swimmer: overview across multiple patients
  • Swimlane: single-patient view with category-based lanes
• AE duration visualization
  • start marker + duration line (color-coded by Grade)
• Action events
  • point events for actions such as hold / dose reduction
• Ongoing event rendering
  • ongoing AEs are shown with an arrow (→) when end date is missing
• Automatic overlap avoidance
  • same-day events are jittered to remain readable
• Clinician-friendly controls
  • a single slider adjusts internal layout parameters for readability
