Purpose: With powerful application programming interface (API) features integrated into the radiation therapy Treatment Planning System (TPS), treatment planning automation, or programmatic modification of treatment planning data, has become a part of clinical routine in many institutions. The purpose of this work is to develop a mechanism for reporting changes in patient treatment planning data performed by software automation routines.
Methods: A SQL Server Reporting Services (SSRS) reporting service integrated with the Oncology Information System (OIS) allows for the creation of custom datasets for report generation. A custom dataset, compiled SSRS query, was generated in Microsoft Report Builder within the Aria Unified Reporting Application (Varian Medical Systems, Palo Alto, CA) to extract structure sets and treatment plans which had been modified by an automation routine. This dataset is then utilized to generate a daily report to be reviewed for auditing patient modified with custom software applications. The report was aggregated over 2 years and 6 months, compared to the output of direct SQL query, and institutional automation use is reported.
Results: Both the SQL query and automation report compiled 2,362 modification events applied to 330 unique patients through the validation and use over 57 unique versions of 15 API assisted scripts. Automation events were recorded for automated treatment plan generation and modification (1,181), automated contouring and contour modification (510), and linear accelerator QA plan generation (669).
Conclusion: Automated plan and structure generation and modification can be a powerful tool for clinical efficiency and standardization. The ability to audit patients which are modified by automated tools is recommended for any clinic utilizing automation.
