How do emergency departments respond to ambulance pre-alert calls? A qualitative exploration of the management of pre-alerts in UK emergency departments

Abstract

BackgroundCalls to emergency departments (EDs) from ambulances to alert them to a critical case being transported to that facility that requires a special response (‘pre-alerts’) have been shown to improve outcomes for patients requiring immediate time-critical treatment (eg, stroke). However, little is known about their usefulness for other patients and the processes involved in ED responses to them. This study aimed to understand how pre-alerts influence patient care in the ED.MethodsWe undertook non-participant observation (162 hours, 143 pre-alerts) and semi-structured interviews with staff (n=40) in six UK EDs between August 2022 and April 2023 focusing on how ED staff respond to pre-alert calls and what influences their response. Observation notes and interview transcripts were imported into NVivo and analysed using a thematic approach.ResultsPre-alert calls involved significant time and resources for ED staff but they were valued as they enabled staff to prepare for a patient’s arrival (practically and psychologically). High demand and handover delays at ED created additional pre-alerts due to ambulance clinician concerns about the impact of long waits on patients.Despite the risk of pre-alert fatigue from calls for patients considered not to require a special response, ED clinicians appreciated timely pre-alert information, perceiving a higher risk from underalerting than overalerting. Variation in ED response was influenced by individual and organisational factors, particularly the resources available at the time of pre-alert. Unclear ED processes for receiving, documenting and sharing information about pre-alerts increased the risk of information loss.ConclusionImproving processes for receiving and sharing pre-alert information may help ED clinicians prepare appropriately for incoming patients. Alternative routes for ambulance clinicians to seek advice on borderline pre-alert patients may help to improve the appropriateness of pre-alerts.
