Night calls attended by one doctor during five consecutive years (1973 to 1977) in a single-handed rural practice, were analysed and divided into two categories: (a) reasonable; (b) unreasonable. Half the night calls were genuine emergencies but 17 per cent were quite unnecessary.
对一名乡村医生在连续五年（1973年至1977年）独自执业期间接到的夜间出诊电话进行了分析，并将其分为两类：（a）合理的；（b）不合理的。一半的夜间出诊电话是真正的紧急情况，但17%是完全不必要的。
