Reactions to fields that fail to meet acceptance criteria, multiple responses accepted

Frequency of responses to the question “If the dose analysis for a beam (measured vs. planned) does NOT pass your standard criteria for passing, how do you respond?”
Response	Response frequency (% of $N=139$)
Examine the field(s) and TPS calculated dose to search for known limitations in the IMRT dose algorithm	71.2%
Examine the other beams in the plan to determine if the magnitude of the error might be significant	61.2%
Change the plan if necessary	51.8%
Examine the delivery records or devices (e.g. machine parameters, log files, physical devices, etc.) for errors	42.4%
Change the criteria to get a higher passing rate and record the justification	39.6%
Change the criteria to get a higher passing rate without recording any justification	6.5%
Not applicable, because my analyses always pass the criteria	2.9%
I do nothing	0.0%
I do something else	59.0%
