Abstract
INTRODUCTION: Diabetes mellitus has been referred to as an 'epidemic' and the World Health Organization reported 422 million people with the disease in 2014. Hypoglycaemia is common among emergency presentations, yet understanding around the utilisation of emergency medical services (EMS) for this is incomplete.Ambulance service referral pathways for those suitable to be treated in the community have been developed as a means of managing this growing demand. However, there is limited evidence to suggest how they should be constructed or implemented.The aim of this review was to examine patients who re-contacted the health services following EMS non-transport for a hypoglycaemic episode and to determine if risk factors could be identified. METHODS: Medline/PubMed and CINAHL online databases were searched for papers published between 1998 and 2018 relating to re-contacts following an interaction with EMS. The Cochrane Library online database was also searched, as well as manual searches from key journals. Relevant clinical manuals, guidelines and specific grey literature were also hand searched. RESULTS: After duplicates were removed, 260 articles were identified, with 41 selected for full review. These were then reduced by excluding those that did not provide any data on re-contact rates/demographics. The remaining papers were then assessed using the Critical Appraisal Skills Programme (CASP) appraisal tool and those identified as of low quality were removed. This produced 17 papers for final inclusion. CONCLUSION: The literature demonstrates that ambulance clinicians can appropriately treat hypoglycaemia in the community and identify those requiring further assessment at emergency departments. However, due to the very nature of diabetes, repeat episodes will and do occur, regardless of community or emergency department management, but these are rarely in the acute phase. Some groups are higher risk, but thorough holistic assessment is vital for identifying those suitable for community management.
