Investigation of ambulatory use of physicians by older persons over an eight-year period reveals that 60 per cent visited physicians with similar frequency for six or more years; 22 per cent regularly made two or less visits and 14 per cent made seven or more visits each year. Analyses reveal cohort effects rather than age effects to be of primary importance in determining an individual's regular pattern of physician use.
一项针对老年人八年期间门诊就医情况的调查显示,60%的人在六年或更长时间内以相似的频率看医生;22%的人定期就诊次数为两次或更少,14%的人每年就诊七次或更多。分析表明,在确定个人常规就医模式时,队列效应而非年龄效应最为重要。
