RESUMEN
More and more elderly people are hospitalised with myocardial infarction. Little is known on their pre-hospital management. In 2001 and 2002, 105 patients aged 80 years or more with suspected ST elevation infarction were managed by the mobile intensive care unit system of the SAMU de Paris-Necker. Diagnosis of infarction was confirmed in 92 (88%). Over 60% of the patients were women. Median time delay from symptom onset to call to the emergency service was 127 minutes, longer in nonagenarians (175 vs 101 minutes). Prehospital use of aspirin was 81% and 39% received an intravenous bolus of heparin. A reperfusion strategy was decided in only 30% (primary PCI: 23/26). One-month mortality was 21% and was related to older age, time when the call to the Samu was made, and absence of current smoking. Overall, the prehospital management of very elderly patients with suspected ST elevation infarction appears far from optimal.

STUDY DESIGN: The French system of Samu-Smur allows the admission of patients directly in intensive care unit (ICU). The aim of this study is to examine the utility of the Samu-Smur with regard to such direct admission (DA). PATIENTS AND METHODS: This retrospective study was performed by the Samu of Paris. Patient details were gathered from three reports: namely hospitalization, transport and regulation reports. These were analysed to decide whether the admission diagnostic was exact, whether the patient's condition was serious, whether the prehospital treatment justified direct admission into an ICU and whether the management was coherent. RESULTS: In 1997, 409 (31%) cases were studied among the 1,350 admitted patients in ICU. Three groups of patients were classified according to admission to surgical (n = 54), medical (n = 180), cardiological ICU (n = 175). The prehospital diagnosis was confirmed by the hospitalization report in 91% of patients in the all three groups. The patient's condition was found to the serious in all cases. Justification of the treatment was respectively found in 96, 88 and 84% of patients. The coherence of management was confirmed in 94, 96 and 89%. DISCUSSION: This study has shown that Samu-Smur management lead to justified DA in ICU for all patients in the study. Prospective studies are needed to show the advantages of this strategy in term of speed of management and outcome.
