Analysis of 1000 consecutive patients brought to the accident and emergency department of a busy district general hospital by ambulance after emergency "999" telephone calls showed that 51.7% of these journeys were unnecessary. Medical cases accounted for a greater percentage of necessary calls than did trauma and surgical cases. Medical education of the public is essential if the number of these calls is to be cut.
对一家繁忙的地区综合医院急诊部接收的1000例连续患者进行分析，这些患者均是在拨打急救电话“999”后由救护车送来的。结果显示，其中51.7%的转运是不必要的。与创伤和外科病例相比，医疗病例在必要呼叫中所占比例更大。如果要减少此类呼叫的数量，对公众进行医学教育至关重要。
