'Blue-lighting' seizure-related needs in care homes: a retrospective analysis of ambulance call-outs for seizures in North West England (2014-2021), their management and costs, with community comparisons

Objectives: With a projected rise in care home residency and the disproportionate impact of epilepsy and seizures on older adults, understanding seizure-related needs in this population is crucial. Data silos and inconsistent recording of residence status make this challenging. We thus leveraged ambulance data to investigate seizure call-out incidence, characteristics, management and costs in care homes compared with the wider community.

Design: Retrospective analysis of dispatch data from a regional English ambulance service over four 9-month periods between 2014/2015 and 2021/2022. Suspected seizures in adults (≥16 years) were identified, with data on location, patient age, severity and management extracted. Incidence rates, trends over time and case characteristics were compared. Costs of ambulance response were estimated, and factors influencing emergency department (ED) conveyance were analysed using logistic regression.

Setting: North West Ambulance Service National Health Service Trust, serving an adult population of ~5.5 million.

Participants: Dispatch data for 98 752 suspected seizure cases.

Results: Care homes, accommodating ~0.8% of the regional population, accounted for 7.2% of seizure call-outs. Incidence was higher in care homes than the wider community (55.71 vs 5.97 per 1000 person/year in 2021/2022) and increased over time. Care home cases peaked around 8:00-9:00. Despite similar or lower severity, they had a higher ED conveyance rate (78.3% vs 70.6%). Conveyance likelihood was influenced by factors beyond severity: reduced in homes specialising in learning disabilities (adjusted OR=0.649) and increased in homes with nursing provision (adjusted OR=1.226). Care homes accounted for 7.26% of the £24 million cost.

Conclusions: This study highlights the growing seizure-related needs in care homes. Despite similar severity, most cases result in ED conveyance. Future research should examine the appropriateness and implications of these transfers, ensuring specialist services support the care home population effectively.
