Study characteristics | ||
Methods | RCT Unit of randomisation: primary care practice/clinic |
|
Participants | Place of recruitment: from local directories ‐ participants were selected if GP practices were involved Numbers randomised: total: 56 (I: 29; C: 27) % Completing final follow‐up: 100% Inclusion criteria: any TIA or stroke, never been exposed to this tool before, access to an organised TIA pathway consistent with the New Zealand TIA guideline Exclusion criteria: did not present to a participating primary or secondary health care providers during the study period or presented without neurologic/ophthalmologic symptoms Mean age years (SD): I: 69.8 (13.3) C: 72.3 (14.0) Gender (men): I: 67, C: 55 Ethnicity: I: European 156/172; C: European 101/119 |
|
Interventions | Intervention details (components, length, frequency): the tool is a Web‐based software program accessed via a GP computer desktop icon. Clicking the icon opens a single page of tick boxes asking for relevant aspects of the presenting illness. Depending on diagnosis and risk estimation, the tool recommends a guideline‐based management strategy. Location: primary care practice/clinic Mode of delivery: face‐to‐face Personnel responsible for delivery: primary care doctor Timing post‐stroke: after initial event Control: usual care |
|
Outcomes | Stroke at 90 days, stroke and TIA at 90 days or vascular event/death | |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | The clusters were general practices randomised one‐to‐one to intervention and control groups using a computer‐generated simple randomisation schedule |
Allocation concealment (selection bias) | Low risk | Central allocation |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Low number of GP practices agreed to join in the study and none were excluded |
Selective reporting (reporting bias) | Low risk | Outcomes were recorded electronically by individual GPs/from GP records |
Other bias | Low risk | The study appears to be free of other sources of bias |
