Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Task-shifted Epilepsy Care Arm (TSC) | In the task-shifted arm composed of thirty clusters, each cluster being a primary healthcare center (PHC) serving a local community, all children who screened positive for untreated epilepsy underwent a diagnostic evaluation by an epilepsy-trained community health worker (CHW), supervised remotely by a physician with epilepsy expertise. Children who were diagnosed with untreated epilepsy after screening positive for epilepsy were prescribed anti-seizure medication (ASM) by the epilepsy-trained CHW according to a task-shifted protocol, and received follow-up care from an epilepsy-trained CHW, according to the specified task-shifted epilepsy protocol. These epilepsy-trained CHWs were supervised remotely by physicians with expertise in epilepsy, and were able to consult physicians with questions on an as-needed basis. | 636 | 763 | OG000 |
| Group 2 | Enhanced Usual Epilepsy Care Arm (EUC) | In the enhanced usual care arm composed of thirty clusters, each cluster being a primary healthcare center (PHC) serving a local community, all children who screened positive for epilepsy were referred to a physician according to standard medical practice at the PHC. The diagnostic evaluation was performed by the physician in the community. Children diagnosed by the physician as having epilepsy were prescribed anti-seizure medication (ASM) and received follow-up care from a physician.~In addition to the usual epilepsy care provided by the physician, each child in the EUC arm was followed by an epilepsy-trained CHW, who followed the child's progress, helped the family navigate the healthcare system (including finding a physician). The usual physician care of epilepsy was enhanced by the support of a CHW, but epilepsy diagnosis and treatment was provided by a physician, not by the epilepsy-trained CHW. | 531 | 725 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- 75% or Greater Reduction in Seizure Frequency as Determined by the Blinded Physician at 24 Months Follow-up Visit
- Description
75% or greater reduction in seizure frequency (including seizure freedom) for 6 months or longer was determined by the blinded physician at the 24-month follow-up visit, compared to seizure frequency reported at time of enrollment. Outcome variance estimates were adjusted for cluster correlation. At 24 months this secondary outcome is captured for 1488 of 1672 randomized, eligible patients. 101/826 (12.2%) EUC patients and 83/846 (9.8%) TSC patients are missing the secondary outcome at 24 months.
- Time frame
- Outcome measured 18 months to 24 months after enrollment
- Population
Outcome variance estimates adjusted for cluster correlation. At 24 months the secondary outcome is captured for 1488 of 1672 randomized, eligible study subjects. 101/826 (12.2%) EUC patients and 83/846 (9.8%) TSC patients are missing this secondary outcome at 24 months, as blinded physicians in some instances were unable to determine the percentage decrease in seizure frequency.
