Details of the QA exercises are provided in the following document:

 

Everyone joining COSTAR needs to do the outlining and planning exercises.

If you were a contributor to PARSPORT, CHHiP or IMPORT High then please contact the QA centre to find out which exercises you do not need to do.

 

Outlining exercise

A COSTAR case must be delineated according to the trial guidelines and returned to the QA centre for analysis

 

 

Planning Exercise

A COSTAR case must be planned both with an IMRT and a conventional plan and returned electronically to the QA Centre for analysis.

 

 

Questionnaires

All three questionnaires need to be filled in.

 

 

Process document

The processes document details all aspects of the tasks and time required along the complete COSTAR patient pathway.

 

 

Case reviews

The case reviews will include a review of the structure outlines and an assessment of the plan. The first 3 patients will be reviewed, and if these are both in the same planning group then the next patient from the other planning group will be reviewed in addition.
