title: Status epilepticus in the elderly patients: A national data study in Thailand.
abstract: There are limited data in terms of incidence, clinical features, and outcomes in elderly patients with status epilepticus (SE) in national level. We retrospectively explored national data in Thailand for reimbursement of all SE in elderly patients admitted in the fiscal year 2004-2012. SE in elderly patients (age>60years old) were diagnosed and searched based on ICD 10 (G41) from the national database of from the National Health and Security Office. There were 3326 SE in elderly patients. The national incidence of SE was highest at 8.78patients/100,000/year in 2012. The average age was 72.02years and most were males (1379 patients; 58.8%). At discharge, 66% of patients had improved and in-hospital mortality rate was 14.5%. Predictors of poor outcomes were older age≥80years, being female, hospital levels, chronic renal failure, central nervous system infection, respiratory failure, pneumonia, septicemia, shock, acute renal failure, and hyperkalemia. In conclusion, the number of cases of SE in elderly patients in Thailand has been increasing annually. Increasing age was associated with poor outcome in admitted elderly SE patients.
