Objective: To classify interhospital transfers by the SUMMA 112 emergency medical
service of Madrid according to scores the patients would have received on the risk scale
for auxiliary transport services, had the scale been used before the transfers.
Methods: We reviewed records and nursing reports for SUMMA 112 interhospital
transfers in the first quarter of 2008 to extract the data needed to apply the risk
Results: Sixty-six patients (16.7%) could have been transferred by 2 attendants in a
conventional ambulance (basic life support), and 275 patients (69.6%) would have
required a conventional ambulance under the care of a nurse plus 1 or 2 ambulance
attendants (intermediate life support). Only 54 patients (13.7%) would have required a
mobile intensive care unit with a physician, a nurse and 2 ambulance attendants.
Conclusion: If the risk scale had been applied before the interhospital transfer of patients
in the study period, 69.6% of the trips could have been carried out under the care of a
nurse, leading to more efficient use of resources and increasing the amount of time in
which mobile intensive care units were available.
