Systematic Errors

Policy Guidance Help System logo

We ask that you note patterns of noncompliance items appearing during your inspections. By pattern, we are referring to the same noncompliance items appearing in a large number of inspections conducted by the same inspector.

In some cases, these patterns could be the result of test equipment failures (example: an inspector's MDH is malfunctioning and all of the dose measurements reach or exceed 300 mrad). In other cases, these noncompliance items could result from regional differences in how mammography facilities operate, an inspector utilizing an outdated policy, or another reason that may need investigating. These patterns could also be the result of random chance. If you come across a string of noncompliances during your inspections, it is important that you contact DMQS ASAP (As Soon As Possible).
