Correlation of age and rurality with low-urgency use of emergency medical services (LUEMS): A geographic analysis

Objectives Studies suggest that addressing the needs of the older population in rural areas may substantially reduce their low-urgency use of emergency medical services (LUEMS). It may ultimately also help improve the efficiency in our health system. There is, however, a dearth of evidence substantiating geographic patterns in LUEMS by different age cohorts. This exploratory study was aimed to clarify the understanding of emergency medical services (EMS) use in Nova Scotia through a geographic analysis. Methods Records with Canadian Triage and Acuity Scale of 4 and 5 were considered as LUEMS. We assessed the distribution of LUEMS incidence rates (proportion of LUEMS out of all EMS uses) by age and rurality, using descriptive statistics and Geographic Information Systems mapping. Results Nearly half of all EMS transports were individuals of 65+ years of age; 35% of those were LUEMS. The rates increased along with the level of rurality, and the older cohort had the highest incidence rates in non-metro communities. High rates were seen primarily in some rural communities farthest away from the capital/tertiary care centre. Conclusion High LUEMS incidence rates are rural phenomena but not specific to the older population. However, the absolute number of LUEMS by the older cohort is significant, and elder-specific interventions in rural regions could still lead to effective cost savings. Further investigation of other factors, such as distance to the emergency department, availability of public transportation, and socioeconomic conditions of EMS users, is needed.
