ALO meaning

An Ambulance Liaison officer (ALO) is the designated ambulance service representative who coordinates liaison with hospitals and other emergency services, particularly during major incidents and periods of acute pressure at emergency departments. The term is not generally defined in legislation or case law; it is an operational title used in UK and Irish emergency planning guidance (e.g. JESIP, NHS/NARU, HSE National Ambulance Service) and local policies. Key features include acting as a single point of contact, managing information flow and handovers, supporting triage and patient prioritisation, logging decisions, and participating in Silver/Bronze command. At hospital sites the role is often called a Hospital Ambulance Liaison Officer (HALO), but responsibilities are broadly similar. For legal practice, the ALO’s records, radio logs and decisions can be critical in inquests (England & Wales), fatal accident inquiries (Scotland), coronial proceedings (Northern Ireland and Ireland), public inquiries, regulatory investigations and civil claims concerning delay, capacity, discharge and major incident response. Employment is typically with the relevant ambulance service (e.g. NHS ambulance trusts, Scottish Ambulance Service, Northern Ireland Ambulance Service, HSE National Ambulance Service). Usage and function are broadly consistent across the UK and Ireland, with local terminology variations.
