When configuring filters for Radiology or ECG, you will need to:
Select Radiology or ECG from the 'Lab' dropdown
Select the appropriate ordered location of your test
Input the relevant conditions
Specify any keywords or criteria that the system should use to flag a result as critical. Rooster will find an exact match of these keywords
For Radiology: AA, A, AY, R1, R1U
For ECG: Abnormal
When configuring filters for your various lab types, specifically Biochemistry, Haematology and Microbiology, it can get more complex. You will need to:
Select your lab type from the 'Lab' dropdown
Select the appropriate location from where the test was ordered from
Input the relevant conditions
Define thresholds to determine criticality based on numeric criteria. For instance, in the example below, any lab tests with ph less than 7.2 and more than 7.6 will be critical
Conditions under Laboratory can be configured according to Keywords: Define specific words to include/exclude when assessing criticality.
Included Keywords: Rooster will flag results containing these terms. (Free-text field for multiple keywords).
Example:
If Included keyword is: Seen 1+ , Seen 2+
We will considered a test result with keyword Seen 1+ to be critical
Excluded Keywords: Rooster will ignore results containing these terms. (Free-text field for multiple keywords).
Example:
If Excluded keyword is: No fungal elements seen , No organisms seen
We will considered a test result with keyword No fungal elements seen to not be critical
Enable "Search for keywords within the first NTE segment" if you want Rooster to search within the first NTE segment following OBX segment.
Determine criticality based on patient’s age:
Patient's age is calculated by rounding down to the nearest whole year. For example, if your birthday is July 10, 2020, and today is July 8, 2024, you are considered 3 years old.
Configure the conditions based on the following options in the dropdown menu:
Determine criticality based on first presentation. This can be further customised by using the "Included Keywords" or "Specimen Source" options "
Per Patient Admission: Flags the test result as critical if it is the patient’s first admission. We determine admission based on visit number .
Within X Hours: This option flags a result as critical only if there has been no previous critical result for the same test within the specified timeframe (X hours).
Example: 'Within 4 Hours':
Time 0 → A critical test result is received (Flagged as critical)
Time 4h → The same test result is received (Not flagged as critical )
Time 4h + 1 min → The same test result is received (Flagged as critical )
If "Included Keywords" is different from previous values is ticked:
If multiple keywords can trigger this filter, any result with a matching keyword will be treated as part of the same presentation.
Subsequent results with different keywords will be considered as a new presentation and flagged as critical.
Example:
First result keyword: Seen 1+
Second result keyword: Seen 2+
Both results are considered critical because the keywords are different
If "Included Keywords" is different from previous values is NOT ticked:
Subsequent results with different keywords will be considered as an existing presentation and not flagged as critical.
Example:
First result keyword: Seen 1+
Second result keyword: Seen 2+
Both results are not considered critical because the keywords are different.
If "Specimen Source or Type" is different from previous values is ticked:
Results from different specimen sources will be considered as a new presentation and flagged as critical.
Example:
A patient diagnosed with TB in the lungs, and a subsequent test shows TB suspected in a wound on the leg. By selecting this option, the test will be flagged as critical because it is from a different specimen source.
If "Specimen Source or Type" is different from previous values is NOT ticked:
Results from different specimen sources will not be flagged as critical unless specified otherwise.
Example:
Case Study: Different Specimen Sources
Scenario: A patient diagnosed with TB in the lungs has a new test that shows TB suspected in a wound on the leg.
If a certain lab result comes from various locations , we allow our users to select 'All locations' to ensure that no result is missed. However , we understand there might still be a few exclusions hence we allow users to select locations to exclude if they have selected 'All Locations' , 'All Clinics' , 'All Wards'.
After we determine the criticality of a result, we will iterate through all routing rules and choose the one which is the closest match to the specialty and the location of the patient. E.g if the patient is from a from A&E, we will select the routing rule shown below :
However, if you would like to route your critical result filter via a specific routing rule, you can select the checkbox below.
You can continue if you would like a critical result to skip manual intervention. This would be useful for R1U results which do not require any action from the Contact Centre.
