Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: MAST_PROPHYLAXIS: To determine the comparative clinical effectiveness (absolute difference in the rate of PTS within the first 2 weeks post-TBI) of a 7-day course of phenytoin or levetiracetam, used as seizure prophylaxis, versus no AED for TBI patients MAST-DURATION: To determine the comparative clinical effectiveness (absolute difference in the rate of late PTS within 24 months post-TBI) of a longer course of AED (at least 6 months) versus a shorter course (up to 3 months) for TBI patients with early seizures. ;Secondary Objective: MAST-PROPHYLAXIS: 1. Compare the rate of PTS within 24 months post-TBI 2. Compare outcomes (extended Glasgow Outcome Scale), cognitive function (Neurobehavioural Symptom Inventory), quality of life (EQ-5D-5L), and adverse events (Liverpool Adverse Events Profile) at 6, 12, 18 and 24 months, between the three arms. 3. Undertake a detailed economic evaluation. 4. To compare the frequency of PTS between the three arms. 5. Mortality at 6, 12, 18 and 24 months. 6. Adverse events of special interest during treatment. MAST-DURATION: 1. Compare outcomes (extended Glasgow Outcome Scale), cognitive function (Neurobehavioural Symptom Inventory), quality of life (EQ-5D-5L), and adverse events (Liverpool Adverse Events Profile) at 6, 12, 18 and 24 months, between the two arms. 2. Undertake a detailed economic evaluation. 3. To compare the frequency of PTS between the two arms. 4. Mortality at 6, 12, 18 and 24 months. 5. Adverse events of special interest during treatment. ;Primary end point(s): MAST-PROPHYLAXIS: Occurrence of PTS within 2 weeks after TBI. MAST-DURATION: Occurrence of late PTS within 24 months after TBI. ;Timepoint(s) of evaluation of this end point: MAST-DURATION: Primary outcome - day 1, discharge, 6, 12, 18 and 24 months. MAST-PROPHYLAXIS: Primary outcome - day 7 and day 14 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary outcomes (both trials: - questionnaires (functional outcomes, neurobehavioral symptoms, HRQOL) - Economic evaluation - Adverse events Secondary outcomes (MAST-PROPHYLAXIS ONLY): - occurrence/frequency of PTS within 24 months;Timepoint(s) of evaluation of this end point: Both trials: All questionnaires at 6, 12, 18 and 24 months. Economic evaluation at 24 months Adverse events during treatment only Secondary outcomes (MAST-PROPHYLAXIS ONLY): - occurrence/frequency of PTS at 6, 12, 18 and 24 months | — |
