Association of quality of paediatric epilepsy care with mortality and unplanned hospital admissions among children and young people with epilepsy in England: a national longitudinal data linkage study

Short-stay urgent hospital admissions of children with convulsions: A mixed methods exploratory study to inform out of hospital care pathways

OBJECTIVE

To inform interventions focused on safely reducing urgent paediatric short stay admissions (SSAs) for convulsions.

METHODS

Routinely acquired administrative data from hospital admissions in Scotland between 2015-2017 investigated characteristics of unscheduled SSAs (an urgent admission where admission and discharge occur on the same day) for a diagnosis of febrile and/or afebrile convulsions. Semi-structured interviews to explore perspectives of health professionals (n = 19) making referral or admission decisions about convulsions were undertaken. Interpretation of mixed methods findings was complemented by interviews with four parents with experience of unscheduled SSAs of children with convulsion.

RESULTS

Most SSAs for convulsions present initially at hospital emergency departments (ED). In a subset of 10,588 (11%) of all cause SSAs with linked general practice data available, 72 (37%) children with a convulsion contacted both the GP and ED pre-admission. Within 30 days of discharge, 10% (n = 141) of children admitted with afebrile convulsions had been readmitted to hospital with a further convulsion. Interview data suggest that panic and anxiety, through fear that the situation is life threatening, was a primary factor driving hospital attendance and admission. Lengthy waits to speak to appropriate professionals exacerbate parental anxiety and can trigger direct attendance at ED, whereas some children with complex needs had direct access to convulsion professionals.

CONCLUSIONS

SSAs for convulsions are different to SSAs for other conditions and our findings could inform new efficient convulsion-specific pre and post hospital pathways designed to improve family experiences and reduce admissions and readmissions.

Type, Etiology, and Duration of Epilepsy as Risk Factors for SUDEP: Further Analyses of a Population-Based Case-Control Study

BACKGROUND AND OBJECTIVES

We conducted a nationwide case-control study in Sweden to investigate the risk of sudden unexpected death in epilepsy (SUDEP) in relation to epilepsy duration, epilepsy type, and etiology in combination with occurrence and frequency of tonic-clonic seizures (TCS) and nocturnal TCS.

METHODS

The study comprised 255 SUDEP cases and 1,148 epilepsy controls. Clinical information was obtained from medical records. The association between SUDEP and risk factors was estimated by odds ratios (ORs) with 95% CIs calculated by conditional logistic regression to account for matching by sex and calendar time.

RESULTS

The risk of SUDEP was elevated in people with focal (OR 1.48, 95% CI 1.00-2.20), generalized and focal (OR 3.51, 95% CI 1.55-7.96), or unknown (OR 2.43, 95% CI 1.29-4.57) vs generalized epilepsy type. Increased risk of SUDEP was also observed in relation to epilepsy with traumatic causes (OR 2.27, 95% CI 1.33-3.89 vs genetic etiology) or short duration (OR 1.71, 95% CI 1.01-2.87 for 0-5 vs 6-15 years duration). Among those with 1-3 TCS during the preceding year, structural epilepsy etiology was associated with a more than 10-fold increase 10.84 (4.85-24.27) in SUDEP risk compared with people with genetic epilepsy without TCS. The risk with ≥4 TCS the preceding year was similar among those with generalized and focal epilepsies. Those with ≥4 TCS had an OR of 210.73 (95% CI 28.40-∞) during years 0-5 compared with those free from TCS and an epilepsy duration of 6-15 years. The combination of short epilepsy duration (0-5 years) and nocturnal TCS conferred an OR of 45.99 (95% CI 12.19-173.61) compared with having longer duration (6-15 years) and being free from nocturnal TCS.

DISCUSSION

Although certain etiologies, such as post-traumatic epilepsy, seem to entail a higher SUDEP risk, our data indicate that frequent and nocturnal TCS carry a similar level of risk whether focal or generalized from onset. The tonic-clonic part of the seizure seems to be decisive for the fatal outcome. SUDEP risk associated with TCS is highest during the first years after the epilepsy diagnosis which calls for effective TCS treatment and vigilance from the onset of diagnosis.

The impact of the time to last seizure before admission to the epilepsy monitoring unit (EMU) on epilepsy classifications

INTRODUCTION AND BACKGROUND

The impact of the timing of the last seizure (TTLS) prior to admission to the epilepsy monitoring unit (EMU) on epilepsy classification is unclear for which we conducted this study.

METHODS

We reviewed patients with epilepsy admitted to EMU between January 2021 and April 2022 and identified TTLS before EMU admission. We considered EMU yield as whether; it confirmed epilepsy classification, added new knowledge to the classification, or failed to classify epilepsy.

RESULTS

We studied 156 patients. There were 72 (46%) men, with a mean age of 30. TTLS was divided according to a one- or three-month cutoff. We confirmed the pre-EMU epilepsy classification in 52 (33%) patients, learned new findings on epilepsy classification in 80 (51%) patients, and failed to classify epilepsy in 24 (15%) patients. Patients with "confirmed epilepsy classifications" reported seizures sooner to EMU admission than other groups (0.7 vs. 2.3 months, p-value = 0.02, 95% CI; -1.8, -1.3). Also, the odds of confirming epilepsy classification were more than two times in patients with TTLS within a month compared to those with TTLS of more than a month (OR = 2.4, p-value = 0.04, 95% CI; 1.1, 5.9). The odds were also higher when the 3-month TTLS cutoff was considered (OR = 6.2, p-value = 0.002, 95% CI; 1.6, 40.2). Confirming epilepsy classification was also associated with earlier seizures recorded at one- or three-month cutoff (OR = 2.1 and OR = 2.3, respectively, p-value = 0.05). We did not observe similar findings when we modified the classification or failed to reach a classification.

CONCLUSIONS

The timing of the last seizure before EMU admission appeared to influence the yield of EMU and enhanced the confirmation of epilepsy classifications. Such findings can improve the utilization of EMU in the presurgical evaluation of patients with epilepsy.

Transition to adult care in epilepsy: A systematic review

The transfer from paediatric to adult care can be a complex process in children with epilepsy. Inadequate care during this phase can affect long-term medical and psychosocial outcomes. The aim of this study was to review studies on transitional care from paediatric to adult healthcare for young persons with epilepsy in order to synthesize evidence for best practice. We undertook a systematic review following PRISMA guidelines and employed narrative synthesis. A total of 36 articles were included, of which 11 were interventional studies and 25 observational studies. Study quality was rated as 'good' for only four studies. Interventions included joint or multidisciplinary clinics, education (patient and health professional education) and extended service provision (Saturday clinics, peer-groups). All studies observed a positive effect experienced by the participants, regardless of intervention type. Observational studies showed that transition plans/programmes are asked for but frequently not existing or not adapted to subgroups with intellectual disability or other neurodevelopmental conditions. The results of this systematic review on transitional care in epilepsy suggest that a planned transition process likely enhances medical and psychosocial outcomes for young people with epilepsy, but the body of evidence is limited and there are significant gaps in knowledge of what efficacious transition constitutes. More studies are needed employing qualitative and quantitative methods to further explore the needs of young people with epilepsy and their families but also robust study designs to investigate the impact of interventions on medical and psychosocial outcomes.

Seizures and Epilepsy in Childhood

PURPOSE OF REVIEW

This article highlights basic concepts of seizures and epilepsy in pediatric patients, as well as basic treatment principles for this age group.

RECENT FINDINGS

Epilepsy is the most common neurologic disorder in childhood. Accurate diagnosis is key; in older children, epileptic seizures need to be differentiated from various paroxysmal nonepileptic events, whereas in neonates, the majority of seizures are subclinical (electroencephalographic). Antiseizure medications remain the first-line treatment, but ketogenic diet and epilepsy surgery have also shown positive outcomes and can decrease drug burden. Genetic causes account for approximately 30% of cases, and the recognition of electroclinical syndromes is being replaced by the concept of genetic spectrums. Precision medicine therapies are promising, but wide application in daily practice still has a long way to go. Early access to specialist centers and optimal treatments positively affects prognosis and future neurodevelopment.

SUMMARY

Although novel findings from all fields of research are being incorporated into everyday clinical practice, a better quality of life for children with seizures and epilepsy and their families is the ultimate priority.

When and why US primary care providers do and do not refer their patients with new-onset seizures or existing epilepsy or seizure disorders to neurologists-2018 DocStyles

Monitoring primary care providers' (PCP) attitudes and experiences with referrals of their patients with new-onset seizures or existing epilepsy/seizure disorders may help evaluate whether interventions to coordinate PCP and neurology care reduce treatment gaps and improve patient outcomes. To examine PCPs' attitudes toward, and experiences with, referral to specialty care of their patients with new-onset seizures or existing epilepsy/seizure disorders, we used cross-sectional 2018 DocStyles data to examine study outcomes. We selected a subsample of respondents who had a practice with at least 1% of patients with an epilepsy/seizure disorder and who answered questions about this disorder. We stratified provider actions, referral behavior, and referral enabling factors and barriers by epilepsy/seizure disorder caseload and provider type. We examined different patterns of responses by referral behavior and provider type. The final sample (n = 1284) included 422 family practitioners, 432 internists, 233 pediatricians, and 197 nurse practitioners. Most PCPs refer their patients with new-onset seizures to a neurologist, particularly to determine or confirm the diagnosis and appropriate treatment. Strikingly, about 40% of PCPs did not indicate a referral if their epilepsy/seizure disorder patient was unresponsive to treatment. Internists less likely referred their patients than pediatricians, nurse practitioners, or family practitioners. Less than one-third of all practitioners consulted seizure treatment guidelines. Prompt appointments, communication with the PCP, the patient's insurance, and referral back to primary care may facilitate referrals. Interventions that enhance enabling factors for guidelines-based care and that can increase opportunities for PCPs to consult with neurologists and/or refer their patients with uncontrolled seizures to specialty care are warranted.

Importance of access to epilepsy monitoring units during the COVID-19 pandemic: Consensus statement of the International League against epilepsy and the International Federation of Clinical Neurophysiology

Restructuring of healthcare services during the COVID-19 pandemic has led to lockdown of Epilepsy Monitoring Units (EMUs) in many hospitals. The ad-hoc taskforce of the International League Against Epilepsy (ILAE) and the International Federation of Clinical Neurophysiology (IFCN) highlights the detrimental effect of postponing video-EEG monitoring of patients with epilepsy and other paroxysmal events. The taskforce calls for action to continue functioning of Epilepsy Monitoring Units during emergency situations, such as the COVID-19 pandemic. Long-term video-EEG monitoring is an essential diagnostic service. Access to video-EEG monitoring of the patients in the EMUs must be given high priority. Patients should be screened for COVID-19, before admission, according to the local regulations. Local policies for COVID-19 infection control should be adhered to during the video-EEG monitoring. In cases of differential diagnosis where reduction of antiseizure medication is not required, consider home video-EEG monitoring as an alternative in selected patients.

Readmission after epilepsy monitoring unit discharge in a nationally representative sample

OBJECTIVE

To determine the 30-day readmission rate after Epilepsy Monitoring Unit (EMU) discharge in a nationally representative sample, as well as patient, clinical, and hospital characteristics associated with readmission.

METHODS

This is a retrospective cohort study of adults discharged from an elective hospitalization with continuous video electroencephalography (vEEG) monitoring, sampled from the Healthcare Cost and Utilization Project's 2014 Nationwide Readmissions Database. Descriptive statistics were used to quantify and characterize readmission within 30 days and logistic regression models were built to examine factors associated with readmission.

RESULTS

6869 admissions met inclusion criteria, with 292 people (4.2 %) readmitted within 30 days. 79.5 % (n = 232/292) of all readmissions were non-elective. Patient characteristics associated with readmission included a higher Elixhauser comorbidity score [adjusted odds ratio (AOR) 1.03, 95 % confidence interval (CI) 1.02-1.04 per 1 point increase in Elixhauser score], a longer length of stay [AOR 1.05, 95 % CI 1.02-1.09 per one day increase in length], non-routine discharge [AOR 1.85, 95 %CI 102-3.38], and comorbid brain tumor diagnosis [AOR 2.55, 95 %CI 1.46-4.46]. Female sex was inversely associated with 30-day readmission [AOR 0.68, 95 % CI 0.54-0.85]. The most common reason for readmission was epilepsy or convulsion (27.6 %), followed by sepsis (5.8 %) and complications of surgical procedures or medical care (5.5 %).

CONCLUSIONS

Patients electively admitted for continuous vEEG monitoring are infrequently readmitted. These data provide a preliminary national readmission benchmark for patients with elective admissions for vEEG monitoring.

Paediatric sudden unexpected death in epilepsy: A parental report cohort

BACKGROUND

Sudden unexpected death in epilepsy (SUDEP) accounts for a large percentage of deaths in children with epilepsy. Contributing factors to paediatric SUDEP are incompletely understood.

AIMS OF STUDY

The Epilepsy Deaths Register (EDR) is an anonymized register that compiles information on deaths related to epilepsy, across all ages and epilepsy classifications. Using the EDR, we sought to identify key risk factors for SUDEP in children to assist the development of preventive measures.

METHODS

All registrations between the ages of 1 and 16 years were reviewed to identify definite or probable SUDEP. These cases were analysed to identify common demographics, comorbidities, monitoring, treatments and circumstances near to the deaths.

RESULTS

We identified forty-six cases (27 males) of definite or probable SUDEP. Paediatric SUDEP is more common in a 12- to 16-year age group and in those with neuro-disability. Most paediatric SUDEP occurs during apparent sleep. There were four cases with a vagus nerve stimulator. SUDEP can occur early after the onset of seizures.

CONCLUSIONS

This is the largest single cohort of SUDEP reported in children. Reports from caregivers can augment population data. Surveillance in sleep is a priority area of development.

The challenge of paediatric epilepsy nursing: An interview with Mrs. Jenny O'Brien, paediatric epilepsy nursing specialist at the Wirral University Teaching Hospital, UK

Epilepsy in childhood is one of the most common neurological disorders encountered in paediatric clinical practice. The current treatment of paediatric epilepsy aims to improve health outcomes, as well as to manage the educational, social and psychological issues that are involved in the quality of life of paediatric patients and their parents. In this direction, in several countries, a specialized, comprehensive, multidisciplinary service has been developed, including paediatric epilepsy nursing, which constitute a key component of this service. According to Mrs. Jennifer O'Brien, one of the pioneering paediatric epilepsy nursing specialists in the UK with a significant contribution in the care of children with epilepsy in Merseyside, the mission of paediatric epilepsy nursing is to enable children with epilepsy and their families to live as normal a life as possible, to ensure that all those who care for the child are well-educated regarding the child's epilepsy and to promote the child's safety and integration into society. She notes that in the past, epilepsy was not considered as a specialty and was looked after by all paediatricians; it is recognised now that it is an incredibly complex group of conditions, which deserves to have specialist management. She believes that although modern technology is crucial in informing and educating families, face to face education and advice is still the most important method of providing support. She highlights the recent advances in genetics of paediatric neurology along with the drive for epilepsy specialists, both nursing and medical, while she estimates that over the following years, paediatric epilepsy nursing will have progressed beyond nowadays expectations.

Dramatic outcomes in epilepsy: depression, suicide, injuries, and mortality

In this narrative review, we will discuss some of the significant risks and dramatic consequences that are associated with epilepsy: depression, suicide, seizure-related injuries, and mortality, both in adults and in children. Considering the high prevalence of depression among people with epilepsy (PWE), routine and periodic screening of all PWE for early detection and appropriate management of depression is recommended. PWE should be screened for suicidal ideation regularly and when needed, patients should be referred for a psychiatric evaluation and treatment. When starting an antiepileptic drug (AED) or switching from one to another AED, patients should be advised to report to their treating physician any change in their mood and existence of suicidal ideation. The risk of injuries for the general epilepsy population is increased only moderately. The risk is higher in selected populations attending epilepsy clinics and referral centers. This being said, there are PWE that may suffer frequent, severe, and sometimes even life-threatening seizure-related injuries. The most obvious way to reduce risk is to strive for improved seizure control. Finally, PWE have a 2-3 times higher mortality rate than the general population. Deaths in PWE may relate to the underlying cause of epilepsy, to seizures (including sudden unexpected death in epilepsy [SUDEP] and seizure related injuries) and to status epilepticus, as well as to other conditions that do not appear directly related to epilepsy. Improving seizure control and patient education may be the most important measures to reduce epilepsy related mortality in general and SUDEP in particular.

Epilepsy deaths in children: Improvements driven by data and surveillance in pediatrics

Epilepsy-related death in children and young people deserves understanding and intervention along with epilepsy-related deaths in adults. Risk of death from epilepsy varies at different ages, and the specific calculations of risk remains complex and varies between studies. There have been several UK studies examining factors associated with epilepsy-related deaths. A UK national audit with other national initiatives has evidenced improving quality of care and more recently allowed service provision factors associated with reduced epilepsy-related death to be evidenced. A national program of health education, formalized epilepsy networks, commissioned surgical pathways, and patient information resources around risk and participation are examples of quality improvement initiatives. Epilepsy-related death is a key outcome, and there remains many difficulties and opportunities at local, regional, and national level to better understand and improve this outcome for children and young people and the adults that they should become.
