Overview of Key Functions
1) The screenshot below shows the ‘Patient Details’ that need to be entered by the treating clinician for an individual patient.
2) After entering the patient’s details, the treating clinician then selects ‘Calculate outcomes’.
3) COMPASS then generates numerical (percentages and natural frequencies – out of 100 patients) and graphical risk presentations for the following outcomes at 3 months with and without thrombolysis:
Independence [complete recovery or minor disability, mRS 0 to 2] – green.
Dependence [moderate to severe disability, mRS 3 to 5] – amber.
Death – black.
Risk of symptomatic intracranial haemorrhage (SICH) and impact of any.
The default graphical risk presentation is coloured pictographs (shown here). By selecting the tabs at the top of the output screen, the same information is displayed in the form of bar charts or flow diagrams alongside stacked bar graphs.
4) This box shows the overall likely net benefit (or harm) from treatment with thrombolysis.
The information in the output screen can be used by clinicians as a guide to decide whether or not offer thrombolysis to stroke patients, and they can show the information on benefits/risks of thrombolysis (via the screen or on paper) to patients/relatives to support high-quality consent and shared decision making.
