To examine trends over time in the rates of admission to hospital for accidents of preschool children and to study patterns of repeated admissions for accidents in these children.
Analysis of linked, routine abstracts of hospital inpatient records for accidents.
Six districts in the Oxford Regional Health Authority covered by the Oxford record linkage study.
Records for 19,427 children aged 5 years and under at the time of first recorded admission to hospital.
Number of admissions to hospital.
Records were analysed in three groups: person based annual admission rates were calculated for each calendar year; each child's first recorded admission in 1976-85 was identified, and the child's record was followed up by linkage for one year from that admission; each child's first recorded admission in 1976-81 was identified and followed up for five years. Overall, 19,427 children from an average annual resident population of 163,000 children in 1976-86 had 20,657 admissions for accidents before they were 6 years of age. Of these admissions 13,983 were for injuries, 5717 for poisonings, and 957 for burns. Admission rates declined after 1976 for poisoning, but no substantial changes over time were found in admission rates for injuries or burns. A total of 17,724 children were followed up for one year and 10,889 for five years; 470 (2.6%) of the children who were followed up for one year and 926 (8.5%) of those followed up for five years had at least one further admission for an accident. Of those followed up for one year the 4 and 5 year old children were least likely and those under 1 and 1 year old were most likely to have a further admission for an accident. The number of children who had more than one accident was greater than would be expected if accidents were random occurrences. Those who had a poisoning at first admission were more likely to have another poisoning than an injury or burn; and those who had a burn at first admission were more likely to have another burn.
Hospital admissions for accidents in children are common: on average 1 child in 88 in this population was admitted each year. Multiple admissions are uncommon but none the less occur more often than would be expected by chance.
研究学龄前儿童因意外事故住院率随时间的变化趋势，并探究这些儿童意外事故重复住院的模式。
对医院住院记录中与意外事故相关的常规摘要进行关联分析。
牛津地区卫生管理局的六个地区，涵盖牛津记录链接研究。
19427名首次住院记录时年龄在5岁及以下儿童的记录。
住院次数。
记录分为三组进行分析：计算每个日历年基于个体的年住院率；确定1976 - 1985年每个儿童的首次住院记录，并从该次住院起通过链接随访一年；确定1976 - 1981年每个儿童的首次住院记录，并并随访五年。总体而言，1976 - 1986年平均每年常住儿童人口为163000名，其中19427名儿童在6岁前因意外事故住院20657次。这些住院中，13983次是因受伤，5717次是因中毒，957次是因烧伤。1976年后中毒的住院率下降，但受伤或烧伤的住院率未发现随时间有实质性变化。共对17724名儿童随访一年，10889名儿童随访五年；随访一年的儿童中有470名（2.6%）、随访五年的儿童中有926名（8.5%）至少因意外事故再次住院。随访一年的儿童中，4岁和5岁儿童再次住院的可能性最小，1岁及以下儿童再次住院的可能性最大。发生不止一次意外事故的儿童数量多于意外事故随机发生时的预期数量。首次住院时中毒的儿童比受伤或烧伤的儿童更有可能再次中毒；首次住院时烧伤的儿童比其他情况更有可能再次烧伤。
儿童因意外事故住院很常见：该人群中平均每年每88名儿童中有1名住院。多次住院不常见，但仍比偶然预期的更频繁发生。
