Method: the PhD thesis is mixed methods. A systematic literature review was conducted to examine literature on the safety of paramedics in interfacility transfers. A retrospective chart review was conducted to examine the incidence, predictors and pattern of adverse events seen in interfacility transfers by paramedics in Saudi Arabia. Following this, a retrospective chart review of interfacility transfers by physicians to the same institution was conducted to compare in-hospital mortality and 30-days survival in both groups. Finally, an expert survey was conducted to examine the consensus of paramedics’ intervention to adverse events seen in interfacility critical care transfers.
Results: the literature showed that the frequency of adverse events seen by paramedics in interfacility transfers ranges from 5.1% to 18%. The rate of adverse events in adult critical patients transferred by paramedics to a tertiary care facility in Saudi Arabia was 13.7%, in-hospital mortality was 30.4% and 30-days survival was 68.1%. There is no significant difference regarding in-hospital mortality or 30-days survival between the paramedic and physician models. The paramedics’ interventions in interfacility adult critically-ill patients were rated appropriate by the majority of the experts in 86.8% of cases; the probability of an intervention to be appropriate was 84.9%.
Conclusion: paramedics with appropriate training and skill can safely transfer critical interfacility adult patients. The mortality outcomes in the paramedic model are comparable to the physician model.
