To examine temporal trends in electroconvulsive therapy (ECT) use among all 12 million Ontario residents between January 1992 and December 2004 and to examine the differential trends in older adults, compared with younger ones.
We undertook a time-series analysis to examine annual trends in the use and prevalence of ECT, using linked provincial datasets. Descriptive data were presented for the population as a whole, and then trends were described separately by age groups (younger and older). As a comparator, we similarly examined antidepressant prevalence for older adults over the same time period.
Overall rates of ECT prevalence were stable. Annual population rates of individuals receiving ECT increased by about 27%, from 12.3 per 100 000 population in 1992 to 15.6 per 100 000 in 1997, and then decreased to 12.5 per 100 000 by 2004. The population rates of ECT were about threefold higher among older adults, relative to the younger population. Antidepressant prevalence increased by 90.1% among older adults over the same time period. The female-to-male ratio was relatively stable over time.
The rate of ECT has been relatively stable since the early 1990s. Older adults were much more likely to be prescribed a course of ECT than younger adults. ECT remains a commonly prescribed treatment, particularly in old age.
研究1992年1月至2004年12月期间安大略省1200万居民中电休克疗法（ECT）使用的时间趋势，并比较老年人与年轻人的不同趋势。
我们采用时间序列分析，利用省级链接数据集研究ECT使用和流行的年度趋势。给出了总体人群的描述性数据，然后按年龄组（年轻人和老年人）分别描述趋势。作为对照，我们同样研究了同一时期老年人的抗抑郁药流行情况。
ECT总体流行率稳定。接受ECT的个体年人口率增加了约27%，从1992年每10万人中的12.3例增至1997年的每10万人中的15.6例，然后到2004年降至每10万人中的12.5例。老年人中ECT的人口率比年轻人高约三倍。同一时期老年人的抗抑郁药流行率增加了90.1%。随着时间推移，女性与男性的比例相对稳定。
自20世纪90年代初以来，ECT使用率相对稳定。老年人比年轻人更有可能接受ECT疗程。ECT仍然是一种常用的治疗方法，尤其是在老年人群中。
