Earlier Mobilization Post Acute Thrombolysis (EMPATHY-I)
October 26, 2023 updated by: Brian Silver
This is a phase III trial trying to determine whether 12-hour bed rest following IV thrombolysis therapy (i.e.
tPA) for ischemic stroke is non-inferior to 24-hour bed rest by measure of outcomes on the modified Rankin Scale (mRS) at 90 days post bed rest.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
90 day mRS
Time Frame: 90 days post bed rest
|
Proportion of patients with a modified Rankin Scale score (min 0, max 5 with 0 being best outcome) of 0-2 at 90 days
|
90 days post bed rest
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pneumonia
Time Frame: Duration of hospitalization stay, average 5 days
|
Determine whether rates of pneumonia are at least similar in the two arms.
Rates will be measured as percentages of the entire population at risk.
|
Duration of hospitalization stay, average 5 days
|
Neurological Worsening
Time Frame: Duration of hospitalization stay, average 5 days
|
Determine whether rates of neurological worsening are at least similar in the two arms.
Rates will be measured as percentages of the entire population at risk.
|
Duration of hospitalization stay, average 5 days
|
Readmission
Time Frame: 90 days post bed rest
|
Determine whether rates of readmission are at least similar in the two arms.
|
90 days post bed rest
|
Venous Thromboembolism
Time Frame: Duration of hospitalization stay, average 5 days
|
Determine whether rates of VTE are at least similar in the two arms.
Rates will be measured as percentages of the entire population at risk.
|
Duration of hospitalization stay, average 5 days
|
Length of Stay
Time Frame: Duration of hospitalization stay, average 5 days
|
Determine whether hospital length of stay are at least similar in the two arms.
This will ve measured in days.
|
Duration of hospitalization stay, average 5 days
