Diverting less urgent utilizers of emergency medical services to primary care: is it feasible? Patient and morbidity characteristics from a cross-sectional multicenter study of self-referring respiratory emergency department consulters

Abstract

Abstract Objective Diversion of less urgent emergency medical services (EMS) callers to alternative primary care (PC) is much debated. Using data from the EMACROSS survey of respiratory ED patients, we aimed to characterize self-referred EMS patients, compare these with non-EMS patients, and assess scope and acceptability of a potential redirection to alternative PC. Results Of n = 292 self-referred patients, n = 99 were transported by EMS. Compared to non-EMS patients, these were older, triaged more urgently and arrived out-of-hours more frequently. The share of chronically and severely ill patients was greater. Out-of-hours ED visit, presence of a chronic pulmonary condition as well as a hospital diagnosis of respiratory failure were identified as determinants of EMS utilization in a logistic model, while consultation for access and quality motives as well as migrant status decreased the probability. EMS-transported lower urgency outpatients visiting during regular physicians’ hours were defined as potential PC cases and evaluated descriptively (n = 9). As a third was medically complex and potentially less suitable for PC, redirection potential could be estimated at only 6% of EMS cases. This would be reduced to 2% if considering patients’ judgment concerning the appropriate setting. Overall, the scope for PC diversion of respiratory EMS patients seems limited.
