Sudden Unexpected Death in Epilepsy (SUDEP) and seizure safety: Modifiable and non-modifiable risk factors differences between primary and secondary care.

INTRODUCTION: The SUDEP and Seizure Safety Checklist ("Checklist") is a risk factors Checklist based around a person with epilepsy (PWE) demographics, seizure, physical, psychological, and lifestyle issues. The Checklist provides a cumulative picture of current risk when applied to a PWE. This study compares and contrasts risk factors of PWE in primary versus secondary care. METHODS: The Checklist was applied to all PWE registered in four primary care practices in central Cornwall UK (pop: 120,000). Individual, modifiable, non-modifiable, and total risk factors and scores were compared between PWE open to secondary care and those not. Statistical tests were used to calculate significance of individual risk factors in primary or secondary care, to compare the total risk scores between care settings and to find the frequency differences of each risk factor between primary practices. RESULTS: People with total and non-modifiable risk scores were higher in secondary care (both p < 0.001). However, modifiable risk scores were higher in primary care (p < 0.001). Psychiatric concerns were the most prevalent modifiable risk factor in primary care. There were significant differences in the risk profiles between all four primary care practices. CONCLUSION: This study highlights that there is a lack of clarity on who is referred to secondary care and when. There needs to be an evidence-based system to allow for a bidirectional flow of PWE considering their fluctuating risk. The Checklist can be a decision support tool to enable this.

SUDEP and seizure safety communication: Assessing if people hear and act.

BACKGROUND: Sudden unexpected death in epilepsy (SUDEP) is a leading cause of death among people with chronic epilepsy. People with intellectual disability (ID) are overrepresented in this population. The SUDEP and Seizure Safety Checklist ("Checklist") is a tool to discuss risk factors influencing seizures and the risk of SUDEP. It includes questions about the availability of nocturnal monitoring. In Cornwall UK, people with epilepsy and ID and their relatives and carers are routinely advised to consider nocturnal surveillance to reduce harm from potential nocturnal seizures. We assessed the retention of advice provided on nocturnal monitoring and if there were differences between those in residential care and those living with their families. METHODS: A postal questionnaire was sent to carers of all people with epilepsy and ID in Cornwall followed by the adult specialist ID epilepsy service. All those who were contacted had received the same advice on SUDEP and nocturnal monitoring at least once in the past year. Each person was categorized into living in a residential setting or with their family group. Intergroup differences were compared using Fisher's exact test. RESULTS: Carers for 170 people were contacted and 121 responded (71%). The family group had statistically more nocturnal seizures than the residential group. While there was no difference in the awareness of SUDEP, the groups differed in their recollection of the person-centered discussion of risk with carers in residential setting being less aware. Where nocturnal monitoring advice was given, it was followed, and previously unknown seizures were identified in 75%. CONCLUSIONS: Carers in residential settings are less likely to recall specific person-centered discussion of risks to the individual they support as compared with those living with families although general awareness of SUDEP and implementing advice such as nocturnal monitoring is present equally in both groups. In improving detection of nocturnal seizures, audio monitoring may be a useful strategy to reduce risk of harm for people with ID.
