Variation in ambulance pre-alert process and practice: cross-sectional survey of ambulance clinicians.

Abstract

Background: Ambulance clinicians use pre-alert calls to inform emergency departments (EDs) about the arrival of critically ill patients. However, there is variation in guidance between local ambulance service policies in terms of what should be pre-alerted and how pre-alerts should happen. We conducted a national online survey to understand the use of ambulance pre-alerts and to inform recommendations for practice and guidance.

Methods: Ambulance clinicians in England involved in pre-alert decision-making were recruited via ambulance trusts and social media to complete an anonymous online survey conducted during May-July 2023. Quantitative data was analysed descriptively using SPSS (version 28) and free-text responses are reported to illustrate the quantitative findings.

Results: We included 1298 valid responses from 10 English ambulance services. There was variation in practice at all stages of the pre-alert process, including the reported frequency of pre-alert (7.1% several times a shift, 14.9% once/two times per month). Most respondents reported that pre-alerts were delivered directly to the ED, but 32.8% reported pre-alerting via an ambulance control room. A third of respondents always used mnemonics to guide a pre-alert (eg, ATMIST (Age, Time of Incident, Mechanism of injury, Injuries, Signs, Treatments)), but 10.2% reported not using any fixed format.The type of guidance used to identify patients for pre-alert varied between clinicians and ambulance services, with local ambulance service guidance being most commonly used, and 20% stating they never use national guidelines. Respondents reported variable understanding of appropriate conditions for pre-alert, with paramedic students particularly wanted further guidance on trauma in older patients and medical pre-alerts. 29% of respondents reported receiving specific pre-alert training, while 50% reported never receiving feedback.

Conclusion: We identified variation in pre-alert processes and practices that may result in uncertainty and challenges for ambulance clinicians providing time-critical care. Guidance and training on the use of pre-alerts may promote more consistent processes and practices.
