Zhou X, Ding D, Wang W, Zhou D, Sander JW. Mortality of Epilepsy in Chinese Populations: A Comprehensive Review. Neuroepidemiology 2024:1-14. [PMID: 39074464 DOI: 10.1159/000540426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Accepted: 07/02/2024] [Indexed: 07/31/2024] Open
Abstract
BACKGROUND Premature mortality is a significant part of the epilepsy burden and may vary across populations, especially between high-income and lower- and middle-income countries. People with epilepsy in China are approximately a fifth of the global population with epilepsy. Previous studies were unlikely to represent the situation in China due to limitations in design, methods, sample size, follow-up time, and other inherent population heterogeneity. SUMMARY By summarising the evidence on the mortality characteristics in Chinese populations with epilepsy in the last 6 decades, we found a median mortality rate of 14.7 (6.8-74.4)/1,000 person-years and a median standardised mortality ratio (SMR) of 4.4 (2.6-12.9) in population-based studies, and a median mortality rate of 12.3 (9.5-101.5)/1,000 person-years and a median SMR of 3.0 (1.5-5.1) in hospital-based studies. Vascular diseases, complications of diabetes, and accidental injuries were the leading causes of death. Risk factors for mortality were reported as older age, male, longer duration, and higher frequency of seizures. Case fatality ratios of status epilepticus in adults were higher than in children, and both increased with follow-up time. Mortality in people with symptomatic epilepsy was high and varied across different primary diseases. KEY MESSAGES The highest mortality rate and sudden unexpected death in epilepsy (SUDEP) incidence were reported from the least developed areas in China. Accidental injuries were the most common causes of epilepsy-related deaths, while the incidence of SUDEP may be underestimated in Chinese populations. Further research is warranted to improve the understanding of premature mortality risk so that preventative measures can be introduced to improve the situation.

Abstract
BACKGROUND Conflicting findings exist regarding the influence of sex on the development, treatment, course, and outcome of status epilepticus (SE). Our study aimed to investigate sex-related disparities in adult SE patients, focusing on treatment, disease course, and outcome at two Swiss academic medical centers. METHODS In this retrospective study, patients treated for SE at two Swiss academic care centers from Basel and Geneva from 2015 to 2021 were included. Primary outcomes were return to premorbid neurologic function, death during hospital stay and at 30 days. Secondary outcomes included characteristics of treatment and disease course. Associations with primary and secondary outcomes were assessed using multivariable logistic regression. Analysis using propensity score matching was performed to account for the imbalances regarding age between men and women. RESULTS Among 762 SE patients, 45.9% were women. No sex-related differences were found between men and women, except for older age and lower frequency of intracranial hemorrhages in women. Compared to men, women had a higher median age (70 vs. 66, p = 0.003), had focal nonconvulsive SE without coma more (34.9% vs. 25.5%; p = 0.005) and SE with motor symptoms less often (52.3% vs. 63.6%, p = 0.002). With longer SE duration (1 day vs. 0.5 days, p = 0.011) and a similar proportion of refractory SE compared to men (36.9% vs. 36.4%, p = 0.898), women were anesthetized and mechanically ventilated less often (30.6% vs. 42%, p = 0.001). Age was associated with all primary outcomes in the unmatched multivariable analyses, but not female sex. In contrast, propensity score-matched multivariable analyses revealed decreased odds for return to premorbid neurologic function for women independent of potential confounders. At hospital discharge, women were sent home less (29.7% vs. 43.7%, p < 0.001) and to nursing homes more often (17.1% vs. 10.0%, p = 0.004). CONCLUSIONS This study identified sex-related disparities in the clinical features, treatment modalities, and outcome of adult patients with SE with women being at a disadvantage, implying that sex-based factors must be considered when formulating strategies for managing SE and forecasting outcomes.

Management of status epilepticus in Malaysia: A national survey of current practice and treatment gap. J Clin Neurosci 2023; 114:25-31. [PMID: 37279626 DOI: 10.1016/j.jocn.2023.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 04/10/2023] [Accepted: 05/10/2023] [Indexed: 06/08/2023]
Abstract
INTRODUCTION Early and effective treatment is fundamental in status epilepticus (SE) management. At the initiative of the Epilepsy Council of Malaysia, this study aimed to determine the treatment gap in SE across different healthcare settings in Malaysia. METHODS A web-based survey was sent to clinicians involved in the management of SE, across all states and at all levels of healthcare services. RESULTS A total of 158 responses were received from 104 health facilities, including 23 tertiary government hospitals (95.8% of all government tertiary hospitals in Malaysia), 4 (80.0%) universities, 14 (6.7%) private, 15 (11.5%) district hospitals and 21 clinics. Intravenous (IV) diazepam was available in 14 (93.3%) district and 33 (80.5%) tertiary hospitals for prehospital management. Non-IV benzodiazepine (rectal diazepam and intramuscular midazolam) was not widely available in prehospital services (75.8% and 51.5%). Intramuscular midazolam was underutilised (60.0% in district and 65.9% in tertiary hospitals). IV sodium valproate and levetiracetam were only available in 66.7% and 53.3% of the district hospitals, respectively. Electroencephalogram (EEG) services were available in only 26.7% of the district hospitals. Non-pharmacological therapies such as ketogenic diet, electroconvulsive therapy, and therapeutic hypothermia were not available in most district and tertiary hospitals for refractory and super-refractory SE. CONCLUSIONS We identified several gaps in the current practice of SE management, including limited availability and underutilization of non-IV midazolam in prehospital services, underutilization of non-IV midazolam and other second-line ASMs, and lack of EEG monitoring in district hospitals and limited treatment options for refractory and super-refractory SE in tertiary hospitals.

Abstract
Earlier and more aggressive treatment of status epilepticus has long been established orthodoxy. In addition to increasing therapeutic options, it is of critical importance to understand whether or not this has translated into improved prognosis. In this review, we examine the evidence as to whether the mortality of convulsive status epilepticus changed over the past few decades. In particular, we discuss a recent systematic review and meta-analysis examining this question and its implications. We discuss potential reasons why there is no evidence of improved prognosis in terms of mortality and ways in which this may be addressed. Finally, we advocate the urgent need for accurate data on functional outcomes in non-fatal cases of status epilepticus. This paper was presented at the 8th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures held in September 2022.

Abstract
Introduction Status Epilepticus (SE) is a diagnostic and therapeutic emergency. The purpose of this study was to establish the frequency, the clinical and therapeutic features of patients with SE at the Department of Neurology of Befelatanana. Methods we conducted a retrospective, descriptive study from January to June 2015. The sociodemographic and clinical features of patients were collected and analyzed on Epi info 7. Results the study involved 53 patients, 54.71% of whom were epileptic (n=29). There was a predominance of patients under 65 years of age (86.79%). The average age of patients was 43.09 years with a sex-ratio of 1.30. Convulsive SE prevailed in 98.11% of cases (n=52). Generalized convulsive SE occurred in 66.03% of cases. STESS below 3 (77.35%) predominated. There were no epileptic abnormalities on standard EEG within 24 hours in all patients with SE. Non-adherence to antiepileptic therapy (9.43%) and sleep deprivation (18.86%) were reported as a trigger factor of SE. No seizure was reported for up to 72 hours after initiation of treatment in 84,90% of cases. We found no significant association between epileptic or non-epileptic status and STESS (p = 0.302), treatment protocol (p = 0.532), and 72-hour remission of seizures (p = 0.211). Conclusion SE affects young and epileptic people. Our treatment protocol allowed for crisis remission within 72h in most cases. A validation study about this therapeutic protocol is required.

Abstract
PURPOSE OF REVIEW Status epilepticus is a serious condition caused by disorders and diseases that affect the central nervous system. In status epilepticus, hypersynchronous epileptic activity lasts longer than the usual duration of isolated self-limited seizures (time t1), which causes neuronal damage or alteration of neuronal networks at a certain time point (time t2), depending on the type of and duration of status epilepticus. The successful management of status epilepticus includes both the early termination of seizure activity and the earliest possible identification of a causative etiology, which may require independent acute treatment. In nonconvulsive status epilepticus, patients present only with subtle clinical signs or even without any visible clinical manifestations. In these cases, EEG allows for the assessment of cerebral function and identification of patterns in need of urgent treatment. RECENT FINDINGS In 2015, the International League Against Epilepsy proposed a new definition and classification of status epilepticus, encompassing four axes: symptomatology, etiology, EEG, and age. Various validation studies determined the practical usefulness of EEG criteria to identify nonconvulsive status epilepticus. The American Clinical Neurophysiology Society has incorporated these criteria into their most recent critical care EEG terminology in 2021. Etiology, age, symptomatology, and the metabolic demand associated with an increasing duration of status epilepticus are the most important determinants of prognosis. The consequences of status epilepticus can be visualized in vivo by MRI studies. SUMMARY The current knowledge about status epilepticus allows for a more reliable diagnosis, earlier treatment, and improved cerebral imaging of its consequences. Outcome prediction is a soft tool for estimating the need for intensive care resources.

Abstract
Outcomes of status epilepticus have not substantially changed over the last decade. Given onset is most often in the community, early termination strategies that are implementable outside of hospitals are of public health importance. This 10-year retrospective single-centre cohort study aimed to determine whether pre-hospital benzodiazepine administration is associated with improved health outcomes in patients with out-of-hospital onset status epilepticus. METHODS We reviewed the medical records of all patients admitted with status epilepticus between 2008 and 2018 at St Vincent's Hospital Melbourne. Data regarding onset setting, medical history, management and outcomes were extracted. RESULTS 72 patients meeting inclusion criteria were identified. Onset of status epilepticus was out-of-hospital for 74% (53/72) of patients, 66% (35/53) of whom were administered a benzodiazepine before reaching hospital, most often by ambulance officers (30/35, 86%). Pre-hospital benzodiazepine administration was associated with a 90% reduction in duration time to seizure cessation (0.65 vs 5.8 days, p = 0.012) and 50% reduction in length of hospital stay (7.6 vs 15.8 days, p = 0.045). In-hospital onset status epilepticus was associated with higher mortality than out-of-hospital onset (26% vs 4%, RR 6.5, p = 0.004). CONCLUSION Pre-hospital benzodiazepines shorten the time to seizure control and length of hospital stay in patients with out-of-hospital status epilepticus, although is under-utilised by both ambulance staff and home carers. Health policy measures to improve ambulance officer and home carer administration skills and confidence may address these issues.

Abstract
AIM To determine the proportion of first status epilepticus (SE) cases that are vaccine-proximate (VP-) and compare clinical outcomes to non-vaccine-proximate (NVP-) cases. METHODS Birth records for 1,440,807 Australian children born in 1998-2012, were probabilistically linked to hospitalizations, deaths, and vaccination history available to 2013. First SE coded hospitalizations were categorized as VP-SE or NVP-SE; clinical severity and post-SE vaccination coverage were compared. SE rates were calculated. RESULTS Of 867 first SE cases (7.9 per 100,000 person-years), 31 (3.6%) were VP-SE; 16 followed dose-1 measles vaccine (1.2 SE per 100,000 doses). Compared with NVP-SE, VP-SE cases were younger (1.0 vs 2.6 years, P < 0.0001) and had longer hospitalizations (4 vs 3 days, P = 0.005). There was no difference in the proportion of VP-SE cases with a coinfection diagnosis compared to NVP-SE (25.8% vs 19.9%, P = 0.42). Controlling for age and history of hospitalization for a neurological condition, intensive care unit (ICU) admission had a stronger association with coinfection (aOR 2.52 (95%CI 1.78-3.57)) than having VP-SE (aOR 1.41 (0.66-3.01)). Groups had similar SE recurrence rates at 12-months (12.9% VP vs 16.9% NVP, P = 0.56) and reduced vaccine uptake following initial SE (from 93.5% to 56.3%). CONCLUSION Proportionally few first SE cases were VP-SE, with higher ICU admission rates mostly explained by younger age and higher coinfection rates. Vaccination plans are needed to improve vaccine uptake following SE.

Abstract
Purpose To assess the clinical-EEG aspects, characterization of subtypes, relationships with prognostic scales and the occurrence of death in elderly patients in the acute phase of nonconvulsive status epilepticus (NCSE). Methodology Clinical variables, EEG data, Status epilepticus severity score (STESS), and the Epidemiology-based mortality score in status epilepticus (EMSE) were related to the death of 96 patients who were over 60 years old, with NCSE. Results NCSE with coma was observed in 31 patients (19 non-subtle and 12 "subtle" SE) and focal NCSE with impairment of consciousness in 65 cases. There were no significant EEG differences according to the type of NCSE. Higher STESS scores occurred in the comatose NCSE patients when compared to those with focal NCSE and impairment of consciousness (4.8 ± 1.2 vs 3.7 ± 1.2; T-Test; p<0.001). It was observed that 25 (26%) elderly died, with a mean survival time of 19.3 days. Elderly people with a higher risk of death are those diagnosed with NCSE with coma (HR 2.76; 95% CI 1.15-6.65; p = 0.023), with STESS≥3 (HR 16.0; CI 1.77-45.08; p = 0.014), with EMSE≥64 (HR 3.67; CI 1.54-8.72; p = 0.003), and those with no history of recurrent SE (HR 6.80; CI 1.42-32.64; p = 0.017), in Cox regression. Conclusion The ictal EEG patterns did not distinguish the subtypes of NCSE. Thirty-day mortality rate was high in elderly patients with NCSE. The clinical variables are related to prognosis. Mortality in the elderly was associated with comatose NCSE patients, with STESS≥3, with EMSE≥64, and no history of recurrent SE.

Abstract
Objective Generalized convulsive status epilepticus (GCSE) is a severe complication of epilepsy, which typically requires extended hospitalization, resulting in substantial resource utilization, hospital expenditures, and patient costs. In this nationwide analysis, we examined hospital length of stay (LOS) patterns for GCSE, and the factors that influence prolonged LOS. Methods We extracted data for adult patients (age 18 years and above) with a primary discharge diagnosis of GCSE from the National Inpatient Sample (NIS) from 2006-2014, the largest all-payer inpatient care database in the United States. We computed LOS (≤1, 2-6, and ≥7 days), overall, and across pre-specified patient-related, hospital-related, and healthcare system-related variables available in the NIS. We identified factors independently associated with prolonged hospitalization (2 or more days), using a multivariable logistic regression model. Results Of 57,832 discharged with a primary diagnosis of GCSE, 6,133 (10.7%) had a LOS ≤1 day, 27,327 (7.3%) stayed for 2-6 days, and 24,372 (42.1%) stayed for ≥7 days. After adjusting for confounders, patients who were older, female, Black, and Hispanic, who underwent continuous EEG video monitoring, were Medicare beneficiaries, had medical comorbidities, or were admitted to large/urban hospitals, were all significantly more likely to have prolonged LOS. Conclusion Over 40% of patients hospitalized for GCSE in the United States spend at least a week in the hospital. Efforts to shorten hospitalization for GCSE may need to primarily focus on patient groups with select sociodemographic and clinical characteristics.

Abstract
OBJECTIVE We aimed to investigate the association between telemedicine and the incidence of status epilepticus (SE) in patients with epilepsy (PWE) during the coronavirus disease 2019 (COVID-19) pandemic using a large population database in the United States. METHODS We performed a retrospective analysis of a private, cloud-based healthcare platform (Explorys Inc., Cleveland, Ohio, USA). We compared each of the previously reported risk factors for SE, such as child, male, and refractory epilepsy, using the chi-square test or Fisher's exact test in two groups: PWE with SE or without SE. We determined whether telemedicine could be a risk factor for the incidence of SE using multivariate binary logistic regression analysis incorporating statistically significant variables in the chi-square test or Fisher's exact test (p < 0.05). Statistical significance was set at p < 0.05. RESULTS We identified 1600 PWE with SE and 61,700 PWE without SE from May 2020 to May 2021. The proportion of children, males, refractory epilepsy, and telemedicine was higher in PWE with SE than in PWE without SE (children: 21.9% vs. 17.7%, p < 0.001; male: 52.5% vs. 48.2%, p = 0.001; refractory epilepsy: 20.6% vs. 8.2%, p < 0.001; telemedicine: 42.5% vs. 23.6%, p < 0.001). The multivariate binary logistic regression model identified four significant variables as follows: child (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.17-1.50), male (OR, 1.19; 95% CI, 1.07-1.31), refractory epilepsy (OR, 2.44; 95% CI, 2.15-2.77), and telemedicine (OR, 2.29; 95% CI, 2.07-2.54). CONCLUSION Telemedicine might be associated with an increased risk of SE in PWE during the COVID-19 pandemic.

Abstract
Status epilepticus (SE) is a neurological and medical emergency, defined as a condition resulting either from the failure of the mechanisms responsible of seizure self-limitation or from the initiation of mechanisms which lead to atypically prolonged seizures. Further than death, SE can have long-term consequences, including neuronal injury, depending on the type, cause and duration of seizures with severe associated disabilities. In Europe, SE shows an incidence rate ranging about 9 to 40/100,000/y. In adults, mortality of patients with SE is ~30%, and even higher (up to 40%) in refractory status epilepticus. To date, etiology, duration, presence of comorbidity, level of consciousness, semiology and age are the main clinical predictors of SE outcome.

Abstract
Background Status epilepticus (SE) can occur in persons with or without epilepsy and is associated with high morbidity and mortality. Methods This survey aimed to record self-reported frequency of SE in persons with epilepsy, its association with clinical characteristics and patient level of information on SE and rescue medication. 251 persons with epilepsy at a tertiary epilepsy center were included in the study. Results 87 (35%) had a history of SE defined as seizure duration of more than 5 min. These patients were less likely to be seizure-free, and had a higher number of present and past anti-seizure medication. Female sex, cognitive disability, younger age at epilepsy onset, defined epilepsy etiology, and focal epilepsy were associated with a history of SE. On Cox regression analysis, female sex, defined etiology and focal classification remained significant. 67% stated that they had information about prolonged seizures, and 75% knew about rescue medication. 85% found it desirable to receive information about SE at the time of initial diagnosis of epilepsy, but only 16% had been offered such information at the time. Conclusion SE is frequent among persons with epilepsy and there remain unmet needs regarding patient education.

Abstract
OBJECTIVES Status epilepticus (SE) may lead to or worsen cognitive dysfunction. Few studies have evaluated magnitude and profile of cognitive dysfunction in patients after SE. Characterization of cognitive deficits may be important for rehabilitation and follow-up. We assessed cognitive function in a consecutive, non-selected group of relatively healthy survivors with a comprehensive neuropsychological test battery. METHODS A total of 33 patients (24 men, 9 women; mean age 54,9 years, mean education 11,8 years) were tested 1 year after SE with Wechsler Adult Intelligence Scale Fourth edition (WAIS-IV), Rey Auditory Verbal Learning Test, subtests from the Wechsler Memory Scale-Revised, Phonemic and Semantic word list generation, and the Halstead-Reitan Battery. Premorbid IQ was estimated with a Norwegian version of the National Adult Reading Test (NART). Results were compared to published norms. Regression analyses and independent groups t-tests were performed to assess the influence of background variables. RESULTS Mean performance generally was about one standard deviation below average. Full scale IQ (WAIS-IV) was significantly reduced compared to estimated premorbid IQ (NART). Negative influence on cognition of brain lesions visible on computed tomography or magnetic resonance imaging and duration of SE >30 min was shown by group comparisons. CONCLUSIONS SE represents a marker for possible cognitive dysfunction, and follow-up with neuropsychological assessment and cognitive rehabilitation seems warranted in most patients. Complex problem-solving abilities with high general sensitivity to brain impairment showed the most prominent reduction. Otherwise, no specific profile of domain affection was found. Structural brain lesions and duration of SE over 30 min represent risk factors for cognitive deficit.

Abstract
Status epilepticus (SE) is associated with high mortality and morbidity. Although SE is frequently seen in elderly patients, there is a lack of a cohesive report of outcome measures and associated factors within this population. Our aim was to systematically review studies reporting outcomes of SE among elderly patients and factors influencing these outcomes. A literature search was conducted in PubMed/MEDLINE, EMBASE, CINAHL Complete, and Cochrane Library from database conception to April 22, 2018. A total of 85 studies were included in this systematic review. The included studies show that mortality is higher in elderly patients than in adult patients. Lesional etiologies, higher number of comorbidities, NCSE, RSE, longer hospital and intensive care unit stays, and infection during hospitalization are associated with poor outcome. Future studies should consider measuring functional outcomes, comparative studies between elderly and adults and AED clinical trials specific for elderly with SE.

Abstract
OBJECTIVE Status epilepticus (SE) is a severe neurologic condition associated with high morbidity and mortality. Population-based studies in adults have found a wide range of incidences in various regions in the world. Although the incidence of SE increases almost exponentially in the elderly, data on census-based population statistics in these studies are scarce. This study provides a critical review with an emphasis on census-based population statistics and study characteristics in adults. METHODS We performed a systematic search of population-based studies on SE in adults in PubMed using "status epilepticus" in combination with "epidemiology", "population", and "incidence" as search terms, and also screened references. For each identified study, we assessed and extracted the respective population pyramids of study and reference population, and study characteristics. RESULTS We identified 22 population-based studies (eleven from Europe, six from North America, three from Asia, one from Africa, and one from Australasia). Incidence rates of patients with SE ranged from 1.29 to 73.7/100,000 adults (95% confidence interval (CI): 76.6-80.3) and of SE episodes up to 81.1/100,000 adults (95% CI: 75.8-87.0). The proportions of elderly and very old patients varied by a factor of 2.6 and 8.5, respectively, depending on study period and place. Further major reasons for heterogeneity were retrospective or prospective study design, definition of time to diagnose SE, variable detection of nonconvulsive SE (NCSE), different etiologies, inclusion of children, recurrent episodes, postanoxic patients, exclusion of patients with preexisting epilepsy or patients identified outside the emergency department, and choice of reference population for age- and gender adjustment. The most recent definition and classification of SE by the International League Against Epilepsy (ILAE) 2015 was used in two studies. Four studies (18.2%) reported incidences per ten-year age strata necessary for age adjustment to various reference populations. CONCLUSIONS This critical review reveals a marked heterogeneity among population-based studies on SE in adults. It provides comprehensive details on census-based population statistics in study and reference populations and various study designs and characteristics essential for direct comparisons between studies. Reporting on these essential key features should be improved in population-based studies on SE.

Abstract
OBJECTIVE The objective of this study was to determine the incidence in Eastern Finland of the different stages of status epilepticus (SE): 1) at the early stage of SE (a prolonged seizure lasting over 5 min);, 2) refractory SE (RSE), and 3) super-refractory SE (SRSE). METHODS Firstly, we conducted a retrospective study on the incidence and outcome of intensive care unit (ICU)-treated RSE and SRSE in the adult population (≥16 years) in Kuopio University Hospital (KUH)'s special care responsibility area (840,000 inhabitants). Secondly, we conducted a prospective study using the International League Against Epilepsy (ILAE)'s new definition for SE (prolonged seizures lasting over 5 min), in adult (≥16 years) patients in the KUH municipality district (North Savo, 248,000 inhabitants). RESULTS The retrospective study on ICU-treated RSE and SRSE from 2010 to 2012 identified 75 patients with RSE, of whom 21% were treated as SRSE, resulting in an annual age-adjusted incidence of ICU-treated RSE of 3.0/100,000 (95% confidence interval [CI]: 2.4-3.8) and 0.6/100,000 (95% CI: 0.4-1.0) for SRSE. In the prospective study of early stage SE (seizures lasting over 5 min), we identified 151 consecutive episodes during the 9-month study period in 2015, corresponding to an annual age-adjusted incidence of 81.1/100,000 (95% CI: 75.8-87.0). In this study, 11 seizure episodes became refractory, resulting in an age-adjusted incidence of RSE of 6.0/100,000 (95% CI: 3.4-10.4), of which seven were treated in the ICU [3.8/100,000 (95% CI: 1.8-7.8)], four were treated palliatively [2.2/100,000 (95% CI: 0.82-5.7)], and two evolved to SRSE [1.1/100,000 (95% CI: 0.3-4.3)]. CONCLUSIONS The new ILAE 2015 definition of SE resulted in a four-fold increase in incidence of SE compared to the earlier 30-min definition reported earlier in Europe. In the epidemiology of RSE, the incidence of ICU-treated RSE, palliatively treated RSE, and SRSE needs to be separated.

Abstract
Background Status epilepticus (SE) is an emergency neurological disorder that affects quality of life and is associated with high mortality risk. Three scores have been developed to predict the risk of in-hospital death, but these scores are poor discrimination of mortality after discharge. This study aimed to develop and validate a simple risk score for long-term mortality in SE patients. Methods This retrospective cohort study was conducted using SE patient data collected from Thailand’s Universal Coverage Scheme database between the fiscal years of 2005 and 2015 and followed-up to 2016. Patients who died in hospital or within 30 days after discharge were excluded. Data were divided at random into either a derivation or validation set. A proportional hazards model for the sub-distribution of competing risks was fitted with backward stepwise method. The coefficients from the model were used to develop a point-based scoring system. The discrimination ability of the model was evaluated using a time-dependent receiver operating characteristic (ROC) curve. Results A total of 20,792 SE patients (with ages ranging from the first day of life to 99 years at first admission) were randomly separated into two groups: 13,910 in the development group and 6882 in the validation group. A sub-distribution hazard model was used to determine nine predictors to be included in the final model, which was, in turn, used to develop the scoring system: age (0–19 points), male (two points), brain tumor (12 points), stroke (three points), cancer (11 points), diabetes (three points), chronic kidney disease (five points), pneumonia (five points), and urinary tract infection (four points). The possible total score ranged from zero to 64 and the cumulative incidence function was used to determine the probability of mortality associated with each total score within the first 10 years after the first admission. The area under the ROC curve (AUC) of the first to last time point ranged from 0.760 to 0.738. Conclusion A nine-factor risk score for predicting 10-year mortality in SE patients was developed. Further studies should focus on external validity and including a range seizure types and duration of seizure as the predictors.

Abstract
BACKGROUND Status epilepticus (SE) is a neurological disorder that affects to the high mortality risk. Several studies reported predictors of mortality in SE; actual causes of death in hospital and out of hospital are limited. This study aimed to describe the case fatality and the causes of death in patients with SE. METHODS This was a descriptive study using the data collected in the national data of the Universal Coverage Scheme in Thailand during the fiscal year 2005 to 2015. Patients who admitted to hospitals and diagnosed as SE were included. The vital status of patients with SE was linked with the Ministry of the Interior and was classified into three phases: in-hospital, short-term, and long-term. RESULTS Among 24,802 patients with SE, 1861 (7.5%) died in hospital, 1910 (7.7%) died within 30 days after hospital discharge, and 4906 (19.8%) died after 30 days. In-hospital death, SE complications (45.9%), seizure (19.6%), and comorbidities (15.4%) were the three common causes of death. While the common causes in short-term and long-term mortality were SE complications (27.7% and 31.0%), comorbidities (28.1% and 26.7%), and other causes (22.4% and 21.9%). CONCLUSION Status epilepticus complications and comorbidities were the common cause of death in patients with SE for all of three periods.

Damian MS, Ben-Shlomo Y, Howard R, Harrison DA. Admission patterns and survival from status epilepticus in critical care in the UK: an analysis of the Intensive Care National Audit and Research Centre Case Mix Programme database. Eur J Neurol 2019; 27:557-564. [PMID: 31621142 DOI: 10.1111/ene.14106] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Accepted: 10/14/2019] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND PURPOSE Factors influencing the outcome after the critical care unit (CCU) for patients with status epilepticus (SE) are poorly understood. Survival for these patients was examined to establish (i) whether the risk of mortality has changed over time and (ii) whether admission to different unit types affects mortality risk over and above other risk factors. METHODS The Intensive Care National Audit and Research Centre database and the Case Mix Programme database (January 2001 to December 2016) were analysed. Units were defined as neuro-CCU (NCCU), general CCU with 24-h neurological support (GCCU-N) or general CCU with limited neurological support (GCCU-L). RESULTS There were 35 595 CCU cases of SE with a 3-fold increase over time (4739 in 2001-2004 to 14 166 in 2013-2016). More recent admissions were older and were more often unsedated on admission. Mortality declined for all units although this was more marked for NCCUs (8.1% in 2001-2004 to 4.4% in 2013-2016 compared to 5.1% and 4.1% for GCCU-L). Acute hospital mortality was two to three times higher than CCU mortality although this has also declined with time. GCCU-L appeared to have lower mortality than NCCUs (odds ratio 0.84, 95% confidence interval 0.72, 0.98) but after post hoc adjustment for case mix there were no differences. Older age and markers of seriousness of morbidity were all associated with increased mortality risk. CONCLUSIONS The number of patients admitted to a CCU for SE is rising but critical care and acute hospital mortality is decreasing. Patients treated in an NCCU have higher mortality but this is explicable by more severe underlying disease.

Abstract
Importance Status epilepticus (SE) is associated with significant morbidity and mortality. Since the late 1990s, a more aggressive management of prolonged convulsive seizures lasting longer than 5 minutes has been advocated. Objective To determine if convulsive SE mortality has decreased during a time of increasing advocacy for out-of-hospital treatment and escalating and earlier treatment protocols for prolonged seizures and SE. Data Source This systemic review and meta-analysis on studies focused on the mortality of convulsive status epilepticus was conducted by searching MEDLINE, Embase, PsychINFO, CINAHL Plus, and the Cochrane Database of Systematic Reviews between January 1, 1990, and June 30, 2017. Study Selection Studies were excluded if they had fewer than 30 participants (<20 for refractory SE), were limited to SE of single specific etiology or an evaluation of a single treatment modality, or were studies of nonconvulsive SE. Data Extraction and Synthesis Data were abstracted and their quality was assessed via a modified Newcastle-Ottawa scale independently by 2 reviewers (A.N. and T.D.G.) using the Meta-analyses of Observational Studies in Epidemiology (MOOSE) guidelines. Data were pooled using a random-effects model. Main Outcomes and Measures The main outcome measure was in-hospital mortality or 30-day case fatality expressed as proportional mortality. Results Sixty-one studies were included in the analysis. The pooled mortality ratios were 15.9% (95% CI, 12.7-19.2) for adult studies, 13.0% (95% CI, 7.2-19.0) for all-age population studies, 3.6% (95% CI, 2.0%-5.2%) for pediatric studies, and 17.3% (95% CI, 9.8-24.7) for refractory SE studies, with very high between-study heterogeneity. We found no evidence of a change in prognosis over time nor by the definition of SE used. Conclusions and Relevance The mortality of convulsive SE is higher in adults than in children and there was no evidence for improved survival over time. Although there are many explanations for these findings, they can be explained by aetiology of SE being the major determinant of mortality. However, there are potential confounders, including differences in case ascertainment and study heterogeneity. This meta-analysis highlights the need for strict international guidelines for the study of this condition.

Abstract
Objective In 2015, the International League Against Epilepsy (ILAE) proposed a new definition of status epilepticus (SE): 5 minutes of ongoing seizure activity to diagnose convulsive SE (CSE, ie, bilateral tonic–clonic SE) and 10 minutes for focal SE and absence SE, rather than the earlier criterion of 30 minutes. Based on semiology, several types of SE with prominent motor phenomena at any time (including CSE) were distinguished from those without (ie, nonconvulsive SE, NCSE). We present the first population‐based incidence study applying the new 2015 ILAE definition and classification of SE and report the impact of the evolution of semiology and level of consciousness (LOC) on outcome. Methods We conducted a retrospective population‐based incidence study of all adult patients with SE residing in the city of Salzburg between January 2011 and December 2015. Patients with hypoxic encephalopathy were excluded. SE was defined and classified according to the ILAE 2015. Results We identified 221 patients with a median age of 69 years (range 20‐99 years). The age‐ and sex‐adjusted incidence of a first episode of SE, NCSE, and SE with prominent motor phenomena (including CSE) was 36.1 (95% confidence interval [CI] 26.2‐48.5), 12.1 (95% CI 6.8‐20.0), and 24.0 (95% CI 16.0‐34.5; including CSE 15.8 [95% CI 9.4‐24.8]) per 100 000 adults per year, respectively. None of the patients whose SE ended with or consisted of only bilateral tonic–clonic activity died. In all other clinical presentations, case fatality was lower in awake patients (8.2%) compared with patients with impaired consciousness (33%). Significance This first population‐based study using the ILAE 2015 definition and classification of SE found an increase of incidence of 10% compared to previous definitions. We also provide epidemiologic evidence that different patterns of status evolution and LOCs have strong prognostic implications.

Abstract
Status epilepticus (SE) is a serious neurologic condition with high morbidity and mortality rates. This study aimed to develop and validate a risk score that is predictive of mortality in patients with SE using clinical factors without electrocardiography. The inclusion criteria of this study were all patients diagnosed with SE and treated between 2005 and 2015. We retrospectively searched for eligible patients using the International Classification of Diseases, Tenth Revision (ICD-10) code for SE (G41) in the national Universal Health Coverage database. The outcome was death at discharge or within 30 days after discharge. Factors-associated death was analyzed using stepwise logistic regression analysis. Risk scores were developed based on the final logistic regression model. The final model was also validated. There were 10 924 patients used for model development and 10 808 used for model validation. The formula to determine the risk score for SE mortality was 5 × shock + 4 × age over 60 years old + 3.5 × heart diseases + 3 × acute renal failure + 3 × septicemia + 2.5 × central nervous system infection + 2.5 × age 41-60 years old + 2 × cancer + 2 × chronic renal failure + 1.5 × age 21-40 years old + 1 × pneumonia + 1 × respiratory failure + 1 × anemia. The risk scores of greater than 4 indicated risk for mortality with a sensitivity of 78.20% and specificity of 75.38%. The area under the receiver-operating characteristic (ROC) curve for death in the final model was 83.59%. The area under the ROC curve for the model validation group was 83.52%. SE patients who had a risk score of 4 or more were at high risk for death. Physicians should be aware of the high mortality rate in these particular patients.

Abstract
BACKGROUND There were several studies that have reported on the long-term mortality rate of status epilepticus (SE). However, these studies were conducted mainly in Western countries using small study populations. This study aimed to evaluate predictors for long-term mortality in SE using the Thai national healthcare database. METHODS This study was conducted using the Thai national Universal Health Coverage (UC) database. The eligibility criteria for this study were that all patients were diagnosed with SE and had been admitted to any hospital between 2005 and 2015. Mortality was defined at discharge and at one, three, five, and 10 years. All eligible patients were categorized as either having survived or having died. The mortality rates were calculated at one, three, five, and 10 years. Factors associated with mortality were analyzed using backward multivariate Cox proportional hazard regression analysis. Kaplan-Meier was performed to estimate the survival rate. RESULTS During the study period, there were 21,732 patients with SE admitted who met the study criteria. The total observation time was 85,821.28 person-years. Of the patients enrolled, 3642 (or 4.24 per 100 person-years [95% confidence interval (CI): 4.11-4.38]) died. Factors positively associated with mortality in patients with SE were central nervous system (CNS) infection, cancer, heart diseases, chronic renal failure, septicemia, pneumonia, respiratory failure, acute renal failure, and shock. Heart diseases had the highest adjusted hazard ratio at 2.69 (95% CI: 2.47-2.93). Two factors were negatively related with SE mortality: hypertension and urinary tract infection. CONCLUSION Long-term mortality in patients with SE had both positive and negative predictors in the national database.

Abstract
Brain abscess (BA) is a severe neurological emergency, which remains a challenge for physicians despite medical advancements. The purpose of this study is to describe the epidemiology of BA in Taiwan and to investigate potential factors affecting the survival of patients with BA. By using the Taiwan National Health Insurance Research Database, we identified hospitalized patients with a discharge diagnosis of pyogenic BA (324.X) between 2000 and 2013. The incidence and in-hospital mortality of BA were calculated based on both age and sex. A total of 6027 BA cases were identified. The overall incidence of BA was 1.88 (95% CI: 1.83-1.93) per 100,000 person-years and increased with age, from 0.58 per 100,000 person-years in individuals aged 0-14 years to 4.67 per 100,000 person-years in those over 60 years of age. The male-to-female incidence ratio was 2.37 (95% CI: 2.24-2.50), with a mountain-shaped distribution across ages peaking at 40-44 years. The in-hospital mortality also increased with age, from 4.22% (95% CI: 2.54-6.97) at 0-14 years to 17.34% (95% CI: 15.79-19.02) in individuals over 60 years of age, without a gender difference (11.9% for males, 12.5% for females). Age, stroke, septicemia, pneumonia, meningitis, and hepatitis were associated with increased risk of in-hospital mortality. There was a male predominance for BA, and both the incidence and in-hospital mortality rates increased with age. Infection-related disease such as septicemia, pneumonia and meningitis were important factors associated with in-hospital mortality. In addition to the original treatment of BA, we suggest paying close attention to potential infections to improve the outcome of BA patients.

Predictors of hospital and one-year mortality in intensive care patients with refractory status epilepticus: a population-based study. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2017; 21:71.

Abstract
Background The aim was to determine predictors of hospital and 1-year mortality in patients with intensive care unit (ICU)-treated refractory status epilepticus (RSE) in a population-based study. Methods This was a retrospective study of the Finnish Intensive Care Consortium (FICC) database of adult patients (16 years of age or older) with ICU-treated RSE in Finland during a 3-year period (2010–2012). The database consists of admissions to all 20 Finnish hospitals treating RSE in the ICU. All five university hospitals and 11 out of 15 central hospitals participated in the present study. The total adult referral population in the study hospitals was 3.92 million, representing 91% of the adult population of Finland. Patients whose condition had a post-anoxic aetiological basis were excluded. Results We identified 395 patients with ICU-treated RSE, corresponding to an annual incidence of 3.4/100,000 (95% confidence interval (CI) 3.04–3.71). Hospital mortality was 7.4% (95% CI 0–16.9%), and 1-year mortality was 25.4% (95% CI 21.2–29.8%). Mortality at hospital discharge was associated with severity of organ dysfunction. Mortality at 1 year was associated with older age (adjusted odds ratio (aOR) 1.033, 95% CI 1.104–1.051, p = 0.001), sequential organ failure assessment (SOFA) score (aOR 1.156, CI 1.051–1.271, p = 0.003), super-refractory status epilepticus (SRSE) (aOR 2.215, 95% CI 1.20–3.84, p = 0.010) and dependence in activities of daily living (ADL) (aOR 2.553, 95% CI 1.537–4.243, p < 0.0001). Conclusions Despite low hospital mortality, 25% of ICU-treated RSE patients die within a year. Super-refractoriness, dependence in ADL functions, severity of organ dysfunction at ICU admission and older age predict long-term mortality. Trial registration Retrospective registry study; no interventions on human participants.

Abstract
The aim of this systematic review was to describe particularities in epidemiology, outcome, and management modalities in the older adult population with status epilepticus. There is a higher incidence of status epilepticus in the older adult population, and it commonly has a nonconvulsive presentation. Diagnosis in this population may be difficult and requires an unrestricted use of EEG. Short and long term associated-mortality are high, and age over 60 years is an independent factor associated with poor outcome. Stroke (acute or remote symptomatic), miscellaneous metabolic causes, dementia, infections hypoxemia, and brain injury are among the main causes of status epilepticus occurrence in this age category. The use of anticonvulsive agents can be problematic as well. Thus, it is important to take into account the specific aspects related to the pharmacokinetic and pharmacodynamic changes in older critically-ill adults. Beyond these precautions, the management may be identical to that of the younger adult, including prompt initiation of symptomatic and anticonvulsant therapies, and a broad and thorough etiological investigation. Such management strategies may improve the vital and functional prognosis of these patients, while maintaining a high overall quality of care.
