Objectives: Emergency medical services (EMS) programs, which provide an alternative to traditional EMS dispatch or transport to the emergency department (ED), are becoming widely implemented. This scoping review identified and catalogued all outcomes used to measure such alternative EMS programs. Data Source: Broad systematized bibliographic and grey literature searches were conducted. Study Selection: Inclusion criteria were 911 callers/EMS patients, reported on alternatives to traditional EMS dispatch OR traditional EMS transport to the ED, and reported an outcome measure. Data Extraction: The reports were categorized as either alternative to dispatch or to EMS transport, and outcome measures were categorized and described. Data Synthesis: The bibliographic search retrieved 13,215 records, of which 34 articles met the inclusion criteria, with an additional 10 added from reference list hand-searching (n = 44 included). In the grey literature search, 31 websites were identified, from which four met criteria and were retrieved (n = 4 included). Fifteen reports (16 studies) described alternatives to EMS dispatch, and 33 reports described alternatives to EMS transport. The most common outcomes reported in the alternatives to EMS dispatch reports were service utilization and decision accuracy. Twenty-four different specific outcomes were reported. The most common outcomes reported in the alternatives to EMS transport reports were service utilization and safety, and 50 different specific outcomes were reported. Conclusions: Numerous outcome measures were identified in reports of alternative EMS programs, which were catalogued and described. Researchers and program leaders should achieve consensus on uniform outcome measures, to allow benchmarking and improve comparison across programs.
RÉSUMÉObjectif: Les programmes de services médicaux d'urgence (SMU), qui offrent une solution de rechange à la répartition traditionnelle des SMU ou au transport classique des malades aux services des urgences (SU), gagnent de plus en plus de terrain. Dans l'examen d'établissement de la portée décrit ici, les auteurs ont relevé et classé tous les résultats utilisés pour mesurer l'efficacité de ces programmes novateurs de SMU. Sources des données: Les auteurs ont entrepris une vaste recherche systématisée de références bibliographiques, et effectué des recherches méthodiques dans la documentation parallèle. Sélection des études: Les critères de sélection comprenaient les appels faits aux services d'urgence 911 ou les malades examinés par les SMU, inscrits dans les rapports de solutions de rechange à la répartition traditionnelle des SMU OU au transport classique des malades au SU par les SMU, ainsi que l'existence d'un critère d'évaluation. Extraction des données: Les rapports ont été classés soit dans la catégorie des solutions de rechange à la répartition des services, soit dans la catégorie des solutions de rechange aux transports effectués par les SMU; quant aux critères d'évaluation, ils ont été classés et décrits.
