ObjectivesIn many emergency medical services (EMS) systems, a direct medical oversight physician is available to paramedics for mandatory and/or elective consultations. At the time of this study, a clinical support desk (CSD) was being implemented within the medical communications center of a provincial EMS system in addition to the physician resource. The CSD was initially staffed with a registered nurse or an advanced care paramedic. The objective of the current study was to compare CSD "peer to peer" consults versus physician consults with regards to consultation patterns, transport dispositions, and patient safety measures.MethodsThis retrospective cohort study analyzed 2 months before (September 1 to October 31, 2012) and 2 months after (September 1 to October 31, 2013) implementation of the CSD. In the before period, all clinical consults were fielded by the direct medical oversight physician. In the after period, consults were fielded by the physician, CSD or both. EMS databases were queried, and manual chart review and abstraction of audio recordings were done. Relapses back to EMS within 48 hours of non-transport were measured.Results1621 consults were included, with 764 consults in the before period and 857 after (p = 0.02). The number of physician consults decreased from 764 before to 464 after (39.2%, p < 0.001), with the CSD taking 325 (37.9%) consults. The CSD was consulted more for police custody and trip destination. The physician was consulted more for cease resuscitation and clinical consults prior to medication administration. Overall non-transport rates were 595/764 before (77.9%), and 646/857 after (75.4%) (p = 0.2). Non-transports were 233/325 (71.7%) via the CSD, 364/464 (78.4%) via the physician, and 49/68 (72.1%) when both were involved (p = 0.07). Rate of relapse to EMS was similar before (25/524, 4.8%) and after (26/568, 4.6%) (p = 0.76), and between CSD (12/216, 5.5%) and physician consults (13/325, 4.0%) in the after period (p = 0.41).ConclusionThe introduction of a novel "peer-to-peer" consult program was associated with an increased total number of consults made and reduced call volume for direct medical oversight physicians. There was no change in the patient safety measure studied.
