Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Healthcare Quality Improvement

Background:

  • Radiation therapy requires precise dose delivery.
  • Dose errors can significantly impact patient outcomes.
  • Standardized methods are needed for error analysis and quality assurance.

Purpose of the Study:

  • To introduce a standardized report form for analyzing radiation therapy dose errors.
  • To classify errors by severity using a 5-type scheme.
  • To assess the effectiveness of the report form in reducing errors and improving quality assurance.

Main Methods:

  • Development of a standardized report form for dose error analysis.
  • Implementation of a 5-type error classification scheme (Type 1: charting errors, Type 3: daily dose errors).
  • Analysis of error rates before and after implementing corrective actions based on report findings.

Main Results:

  • Type 1 (charting) and Type 3 (daily dose) errors were the most frequent.
  • Implementation of the report form led to a significant reduction in Type 1 errors, from 17% to 3.9%.
  • An average Type 3 error rate of 1.7% was observed, considered consistent with normal operations.

Conclusions:

  • The standardized report form is effective in documenting and correcting radiation therapy dose errors.
  • The form serves as a valuable tool for quality assurance programs.
  • Systematic analysis and procedural correction based on the report form enhance treatment safety.
