[Evaluation of an activity score of prehospital medicine: activity scoring using Smur (CAS)]. / Evaluation d'un score d'activité en médecine préhospitalière: codage d'activité Smur (CAS).

OBJECTIVE: The activity of prehospital emergency medicine (PEM) teams is mainly assessed by the amount of medical interventions and their duration. However, these two parameters do not reflect workload correctly. The aim of this study was to compare a new activity scoring system for PEM teams (CAS) with the standard TISS score. STUDY DESIGN: Prospective comparative study. PATIENTS: This study included 4,650 patients, with a median age of 39 years [0-100], attended by PEM teams during 4,189 ambulance transports (83% primary transports and 17% interhospital transfers). METHODS: The CAS score derived from Omega scoring system is the sum of 51 items specifically suited for PEM, each one being rated 1, 3, 6 or 10. CAS and TISS, were prospectively determined for all medical ambulance transports over 1.5 year. Transport data and main diagnosis were collected. Results were analysed with non parametric statistical tests. RESULTS: Median duration of interventions (39 min [0-475]) and median CAS score (7 [0-72]) were comparable (R' = 0.38, P < 0.001). Median TISS was 3 [0-30]. CAS score was correlated with TISS (R' = 0.92, P < 0.001). CAS score was higher in men than in women (7 [0-72] vs 7 [0-45], P < 0.001). CAS scores in patients with cardiologic (11 [0-72]), respiratory (9 [0-31]) or neurological insults (9 [0-43]) were significantly higher than those of patients with other insults (P < 0.001). CONCLUSION: The CAS scoring system is a valuable indicator of medical team prehospital workload, probably more suited for prehospital emergency medicine than TISS.

[Assessment of imminence of unplanned out-of-hospital deliveries in Guadeloupe: experience of the mobile emergency and resuscitation service of Pointe-à-Pitre]. / Évaluation de l'imminence de l'accouchement inopiné extra-hospitalier en Guadeloupe : expérience du service médical d'urgence et de réanimation de Pointe-à-Pitre.

OBJECTIVES: Medical tools to determine the imminence of unplanned out-of-hospital birth have not been validated. The main goal of this study was to analyze assessments of the imminence of these deliveries, by methods such as the Manilas score and the need to push. PATIENTS AND METHODS: All calls made to the Emergency Medical Aid Service in Guadeloupe concerning risks of unplanned delivery between January 1st and June 30th 2011 were reviewed retrospectively, and 69 of the 85 cases cared for by the hospital mobile emergency unit were included. RESULTS: Risks of unplanned out-of-hospital deliveries represented 1.9% of the calls during the study period. The Malinas score was used for dispatching in only 13% and was not used for intervention in any case. It was estimated that the need-to-push feeling was used for 58% (dispatching) and 54.5% (intervention) of patients. Its sensitivity, specificity and predictive values were higher than those of the Malinas score in dispatching and substantially higher in intervention. CONCLUSION: These results argue for the development of tools for estimating the imminence of unplanned delivery. Such tools should be applicable in extra-hospital emergency situations to ensure their use in practice.
