The CLOQS Trial - Countdown Lights to Optimize Quality in Stroke

Not Applicable

Completed

• Conditions: Acute Stroke
• Interventions: Other: LED stopwatch-clock timers

• Registration Number: NCT01148602
• Lead Sponsor: Sunnybrook Health Sciences Centre

Brief Summary

To reduce door-to-needle times in acute stroke treatment. Using an organizational behaviour intervention (a large stopwatch), we will post a visual cue to remind all parties that "time is brain". We hypothesize that this simple visual cue will improve door-to-CT scan times and door-to-needle treatment times, and thus improve treatment response, and reduce adverse events.

Detailed Description

We will construct a large, "in-your-face" red LED stopwatch-clock that is the intervention. The clock will be attached to the stretcher of patients presenting for hyperacute stroke treatment (consideration of tissue plasminogen activator (tPA) treatment at the moment of their Emergency department arrival. This will act as a constant visual reminder to all team members (physicians, RN's, CT technologists) of the urgency of the situation. The study will be a block randomization, by week of presentation. All patients presenting during "on" weeks will have a stopwatch timer with them during the hyperacute stroke workup. During "off" weeks, the clocks will not be used.

Arm && Interventions

Group	Intervention	Description
'On Clock"	LED stopwatch-clock timers	LED stopwatch-clock timers will be posted for all patients presenting during "ON clock" weeks. All patients presenting with hyperacute stroke will be managed normally with the addition of a visual stopwatch timer.

Primary Outcome Measures

Name	Time	Method
