[Application of portable electroencephalograph in patients with epilepsy and establishment of medical platform].

To provide a portable electroencephalograph that can facilitate long-term monitoring of epilepsy patients outside the hospital, and establish a medical platform for epilepsy data monitoring and treatment. From June 2018 to October 2019, twenty-nine patients from Huashan Hospital (superior hospital) and Jing'an District Central Hospital (subordinate hospital) of Fudan University were enrolled in the study. Among them, twenty-eight cases were diagnosed with epilepsy and 1 case was epileptic seizure. Electroencephalogram (EEG) was collected by portable electroencephalograph once a week and followed up for three months. The seizure frequency, seizure form, medication type, EEG lead number and positive rate were recorded. Patients' medical records and EEG data were uploaded to the cloud database to build a medical alliance platform. Doctors of different levels of hospitals couldobtain diagnosis and achieve resource sharing based on the platform. The data was statistically analyzed using SPSS 18.0. The EEG data collected by the portable electroencephalograph hadfewer artifacts, complete sleep cycle, and could record the interictaldischarges. Twenty-nine patientsunderwent a total of 148 EEG monitoring during the three-month follow-up. Eighty-five cases of epileptic discharges were detected, and the EEG positive rate was 57.4%. The positive rate of EEG in patients with generalized seizures (84.9%) was higher than that in patients with focal seizures (42.1%) (0.01); the positive rate of EEG in patients with 2-3 antiepileptic drugs and patients with frequent seizures within three months were also higher (0.05). Doctors in the superior hospital in the platform make diagnosis and treatment suggestions according to the above data. Elevenseizure-free patients and four patients with fewer seizures and discharges were diverted to the community hospital for follow-up. Fourteen patients with poor seizure control and/or continuous epileptic discharges were diverted to the superior hospitalto adjust the medication. Doctors of subordinate hospital acquired the diagnosis and treatment suggestions through the platform, and then strengthened the daily care and follow-up. Combined with a portable electroencephalograph, the current study establishs a medical platform for patients with epilepsy to achieve long-term monitoring and rational use of medical resources.
