AAOM Handbook

Quality

All high cost low sample rate activities should be reviewed for a reasonable forward period - suggested 12 months.

Where changes to the underlying cost drivers for high sample rate Activities are able to be predicted these should be reviewed within 1 cost measurement period (typically 1 month). Where changes to the underlying cost drivers for high sample rate Activities are not able to be predicted these should be reviewed immediately a special cause event in the cost measurements is recognised. This review should be initiated on the basis of standard statistical data review criteria;

• a single point outside of control limits, • seven points above or below the mean, • seven points moving in the same direction.

Time

At each costing measurement interval (typically monthly).
