Admission rates, multiple admissions per individual and time spent in hospital in general medical and geriatric care are described using data from the Oxford Record Linkage Study from 1968-86. For patients aged 15-39 years, age-specific admission rates did not vary appreciably with age and were a little higher in women than in men. For patients aged 40 years and over, admission rates rose steeply with age and were considerably higher in men than in women. Admission rates, measured as episodes, increased over time by 3.4% per year in women and 3.7% in men. Measured as individual people admitted per year, they increased by 2.2% per year people in women and 2.6% in men. Expressed as age-standardized rates, they increased by 1.5% per year in women and 1.8% in men. The greater rise in episodes than in people treated reflected an increase in repeat admissions per patient admitted. Mean length of stay per hospital episode and total time spent in hospital per patient admitted per year both showed a consistent decline over time. Increases in admission rates were seen in all of the common broad clinical groupings studied, except infectious diseases which, as a group, showed a mean annual decrease of just over 2% per year.
利用1968年至1986年牛津记录链接研究的数据，描述了普通内科和老年护理中的住院率、个体多次住院情况以及住院时间。对于15至39岁的患者，特定年龄的住院率随年龄变化不明显，女性略高于男性。对于40岁及以上的患者，住院率随年龄急剧上升，男性明显高于女性。以发作次数衡量的住院率，女性每年增长3.4%，男性每年增长3.7%。以每年住院的个体人数衡量，女性每年增长2.2%，男性每年增长2.6%。以年龄标准化率表示，女性每年增长1.5%，男性每年增长1.8%。发作次数的增长幅度大于接受治疗的人数，这反映出每位住院患者的重复住院次数增加。每次住院的平均住院时间和每年每位住院患者的总住院时间均随时间持续下降。在所研究的所有常见广泛临床分组中，住院率均有所上升，但传染病作为一个整体，平均每年下降略超过2%。
