RO-ILS Education

Aggregate Data Reports 

The Radiation Oncology Healthcare Advisory Council (RO-HAC), with the help of Clarity PSO, analyze, interpret and report on data submitted into RO-ILS. 

Aggregate reports are posted on the RO-ILS website to facilitate shared learning across the field of radiation oncology. These reports provide insight on patient safety in the form of a summary report card, case reviews and detailed commentary. As the program has grown and matured, the frequency and format of education has evolved. Currently, aggregate reports are released twice a year and are supplemented by independent case studies. Beginning with the Third Quarter 2016 report, ASTRO began offering associated continuing medical education.

Below, please find the recent aggregate reports and associated CME:

Case Study

Starting in 2018, RO-ILS began releasing RO-ILS case studies. These stand-alone case studies summarize a RO-ILS event and provide learning, feedback and suggestions from RO-HAC. When possible, RO-ILS seeks to engage the practice that reported the event in an open dialogue and development of the case study. With Clarity PSO working as an intermediary, practices who agree to collaborate are always given the option to remain anonymous.

Year in Review

In honor of the RO-ILS June 2014 launch, an annual report will be published describing the state of the program and highlighting developments and quarterly report findings.


RO-ILS participants receive regular emails (previously known as 'Tips of the Month') with program information, suggestions and reminders. Previous announcements have included RO-ILS specific information including best practices for tracking trends internally and a guide to utilizing the Analysis Wizard in the RO-ILS portal. Additionally, these announcements educate users on the broader scope of patient safety and incident learning including how to write a comprehensive narrative and understanding patient safety work product (PSWP). Below, please find some examples of broadly-applicable 'Tips of the Month':

Published Manuscripts

"A Report from the First Year of Experience," written by RO-HAC and staff, was published in the September-October 2015 Safety Issue of Practical Radiation Oncology (PRO). To learn more about the full process from conception to beta testing and finally operation, read the 2015 PRO article.

"Common error pathways seen in the RO-ILS data that demonstrate opportunities for improving treatment safety," written by RO-HAC, was published in the March-April 2018 Issue of PRO. To learn more about the common patterns for the more severe events reported in RO-ILS, read the 2018 PRO article.


The Radiation Oncology Healthcare Advisory Council (RO-HAC) is a group of radiation oncology professionals who provide subject-matter expertise, including helping Clarity PSO analyze, interpret and report on data submitted into RO-ILS. RO-HAC members include radiation oncologists, physicists, dosimetrists and other patient safety experts. Members of RO-HAC receive an honorarium and must sign a contract with Clarity PSO before accessing any data. The RO-HAC operates as part of Clarity PSO's patient safety evaluation system and is not subject to either ASTRO or AAPM review or oversight. RO-HAC members must comply with ASTRO's Conflict of Interest Policy for RO-HAC.
