The patient’s INR
result is entered into the system. The system then uses the Target
INR setting for the
patient to decide if the result is In Range, Low or High.
The current result and INR history are
used to see if a trend can be observed that meets the criteria
required to activate any of the dose change Triggers or Rules defined
in Dawn AC.
These rules can be adjusted by
you in the Enterprise edition of Dawn AC to
meet your local practice, although we supply the system with proven
set of rules. This would allow you standardise practice.
Note, there are three types of Trigger.
If a Dose Change Trigger is activated, a modified dose will be
calculated. If a Warning Trigger is activated, a warning will be
produced. If a Dose Prevention Trigger is activated, an automatic dose
calculation will be prevented and the dose will have to be set
manually.
Note, a dose change cannot occur
automatically if the current result is in range.
If a dose change is activated then the
percentage dose change given can be calculated by an empirical
equation. This equation is available, on request, to licensed
customers.
Note, you can override or manually
adjust the suggested dose change.
Note, a maximum percentage dose change
can also be set. If the new dose percentage change is greater than
this maximum percentage change, the dose adjustment is reduced to
match the maximum percentage change allowed.
The dose value is then converted into a
dosage instruction in a specified format of your definition.
When a dose is calculated, the
interval to the next test will also be calculated based on the
previous history of the patient. The user can specify when a
particular interval is to be chosen by setting different criteria.
