Recipe Name:

Identify patients with a stroke or TIA not on antiplatelet therapy


Antiplatelet therapy significantly reduces stroke, MI or vascular death (17.8% compared with 21.4%). Aspirin remains common although duel therapy with extended release dipyridamole (200mg  bd) is more effective (relative risk reduction 18%) if tolerated 1.  Clopidogrel alone may also be used and is as effective as aspirin and dipyridamole2.

Identify all active stroke/TIA patients who are not on antiplatelet therapy.

CAT Starting Point:

  1. CAT Open
  2. Population Extract Loaded and Extract Pane "Hidden"
  3. OPTIONAL ONLY{*}: Filter Pane Open and, under the General Tab, "Active Patients (3x < 2 years)" selected

*The decision to select either "Active" or "All" patients is left to the practice to make

In the Filters Pane:

1. In the "Conditions" tab select "Stroke" Yes 

2. In the "Medications" tab under "Medications – Heart" select

  1. Aspirin - No
  2. Clopidogrel - No

3. Click "Recalculate"  

4. Click "View Pop"


This will list all active (if selected on the general filter tab) patients who had a stroke currently not taking anti-platelet medication and their last visit and assigned provider.


  To Export Patient List to Microsoft Excel:

1.  Click on the “Export Icon”  at the top of the Patient Reidentification window.

2.  Click on “Excel”

3.   Choose a file name and a location to save to (eg. Create a folder C:/ClinicalAudit/CAT Patient FollowUp)

4.  Click “Save”

The steps above will produce a list of patients with contact details in MS Excel which can then be used to:

1.   Go back through the individual patient records in the GP Clinical Desktop System (CDS) and update known records

2.  Phone patients to update their record

3.  Produce a mail merge to recall patients for follow up

Create a prompt to display in Topbar

Remember you need to be in the CAT4 Daily View to be able to create prompts. Other pre-requisites are:

  • Topbar is installed
  • CAT4 is linked to Topbar via Edit/Preferences/Topbar - check here for details: Linking CAT to Topbar

To start click on the 'Daily View' icon on the top of your CAT4 screen:

Once you have applied the filter(s) and displayed the patients of interest as described above, you can create a prompt that will be shown to all clinicians using Topbar if a patient meeting the prompt criteria is opened in their clinical system. The full guide is available at CAT PLUS PROMPTS and a short guide on how to create prompts in CAT4 can be found at  Creating a Prompt in CAT4

To start you have to use the drop-down menu at the bottom of the patient details report and select "Prompt at Consult - Topbar" then click on "Go" to give the new prompt a name.

The name you enter is the prompt text displayed in Topbar, so choose a simple but clear name that tells the clinician seeing the prompt what should be done.
