Comparative Study
Emergency medical dispatching by general practitioners in Brussels.
The objective of this study was to introduce general practitioners (GPs) to the existing emergency medical services (EMS) system, in order to improve the response to emergency residential calls. The study was based in Brussels, which has 1 million residents. A GP dispatcher (GPD) was placed in the emergency dispatch centre, with a stand-by GP, together with adequate equipment, at his or her immediate disposal. ⋯ Following stand-by GP intervention, only 25% of visited people are hospitalized. Introduction of GPs is relevant because they are used to discerning critical events from a large number of non-critical disorders. The GPD can adapt the emergency medical dispatching by using a stand-by GP, without compromising the medical assistance to vital emergencies.

In order to evaluate the local emergency medical dispatch centre, 4601 calls were analysed. Information was obtained from the tape recordings of the dispatch centre and standardized reports from the basic life support (BLS) teams, advanced life support (ALS) teams and the emergency departments of all receiving hospitals in the study area. The need for prehospital ALS care was assessed 'post hoc', based on the clinical findings at the scene and in the emergency department. ⋯ In the 633 cases judged 'post hoc' to require prehospital ALS care, an ALS team was not sent in 260 (41%) or sent with some delay in 112 (18%). Of the 819 interventions of the ALS teams, 446 (54%) dealt with cases not requiring that level of care. With regard to the role of the dispatchers in the mismatches between the medical needs of the patients and the level of care sent, underestimation and overestimation of the severity of the emergency by the dispatchers was found in 31% and 22% cases respectively.

Comparative Study
The role of protocols and professional judgement in emergency medical dispatching.
The task of evaluating incoming calls to Emergency Medical Services (EMS) systems in order to determine the most appropriate response is performed in many different ways in current EMS systems. At one end of the spectrum, the process is entirely dependent on the judgement of professionals, while at the other end protocols specify the exact questions to be asked and corresponding decisions. This case study describes the experience of the Montreal EMS system, Urgences santé, where professional telephone evaluation performed by nurses since 1981 was replaced by a protocolized system in 1992. ⋯ Many contextual factors influence the organization of telephone assessment in EMS systems. This case study suggests that professional judgement may be most useful in contexts where the demand for EMS services often exceeds the availability of resources. On the other hand, protocolized systems may be more appropriate in the absence of such constraints, and where the litigation context prohibits the occurrence of any false negative.
