Predictors of Outcomes of Convulsive Status Epilepticus

September 26, 2026 updated by: Hagar Khaled Abo Daif, Assiut University

Predictors of Outcomes of Convulsive Status Epilepticus: A Hospital-Based Study

Status epilepticus is a life-threatening neurological emergency characterized by prolonged seizures or multiple seizures occurring without the patient regaining consciousness between episodes. Convulsive status epilepticus is associated with high rates of morbidity and mortality if not promptly recognized and controlled. While prognostic factors have been studied in various populations, data regarding clinical predictors and hospital outcomes in Upper Egypt remain limited.

The purpose of this prospective, hospital-based observational study is to identify the clinical predictors of short-term outcomes among adult patients presenting with convulsive status epilepticus admitted to Assiut University Hospitals.

All eligible participants aged 18 years and older admitted with convulsive status epilepticus will receive standard-of-care medical management according to institutional clinical protocols. Researchers will systematically collect clinical data, including demographic factors, seizure semiology and duration, underlying etiologies, laboratory tests, neuroimaging findings, and electroencephalography (EEG) results.

Participants will be followed throughout their hospital stay to assess functional outcome at discharge using the Modified Rankin Scale (mRS), in-hospital mortality, response to antiseizure treatment, development of refractory or super-refractory status epilepticus, requirement for intensive care unit (ICU) admission or mechanical ventilation, and length of hospital stay.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Study Population

Adult patients presenting with convulsive status epilepticus admitted to the emergency, neurology, or intensive care departments at Assiut University Hospitals. The population includes individuals aged 18 years and older presenting with continuous convulsive seizure activity lasting more than 5 minutes or two or more discrete seizures without full recovery of consciousness between episodes.

Description

Inclusion Criteria:

  • Age 18 years or older.
  • Presentation with convulsive status epilepticus, defined as continuous convulsive seizure activity lasting more than 5 minutes or two or more discrete seizures without full recovery of consciousness between episodes.

Exclusion Criteria:

  • Functional or dissociative (psychogenic non-epileptic) status.
  • Acute cardiac arrest with motor phenomena due to cerebral anoxia.
  • Movement disorders mimicking seizures (e.g., acute extrapyramidal side effects, chorea, or dyskinesias).
  • Age younger than 18 years.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Convulsive Status Epilepticus Cohort

Adult patients (aged 18 years and older) admitted to Assiut University Hospitals presenting with convulsive status epilepticus, defined as continuous convulsive seizure activity lasting more than 5 minutes or two or more discrete seizures without full recovery of consciousness between episodes.

All enrolled participants receive standard-of-care medical management according to institutional guidelines, including first- and second-line antiseizure medications, anesthetic agents, and intensive care or mechanical ventilation when clinically required. Demographic characteristics, clinical features, etiology, laboratory investigations, neuroimaging, electroencephalography (EEG), and treatment responses are prospectively collected throughout hospitalization until discharge to determine clinical predictors of outcome.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Modified Rankin Scale Score
Time Frame: Up to 30 days

Functional outcome assessed using the Modified Rankin Scale (mRS). The mRS is an ordinal scale ranging from 0 (no symptoms) to 6 (death). Scores 0-2 indicate functional independence, while scores 3-6 indicate functional dependence or death. Higher scores reflect worse clinical outcome.
Up to 30 days

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
