This study examined trends for all first hospital admissions for peripheral artery disease (PAD) in Scotland from 1991 to 2007 using the Scottish Morbidity Record.
First admissions to hospital for PAD were defined as an admission to hospital (inpatient and day-case) with a principal diagnosis of PAD, with no previous admission to hospital (principal or secondary diagnosis) for PAD in the previous 10 years.
From 1991 to 2007, 41,593 individuals were admitted to hospital in Scotland for the first time for PAD. Some 23,016 (55.3 per cent) were men (mean(s.d.) age 65.7(11.7) years) and 18,577 were women (aged 70.4(12.8) years). For both sexes the population rate of first admissions to hospital for PAD declined over the study interval: from 66.7 per 100,000 in 1991-1993 to 39.7 per 100,000 in 2006-2007 among men, and from 43.5 to 29.1 per 100,000 respectively among women. After adjustment, the decline was estimated to be 42 per cent in men and 27 per cent in women (rate ratio for 2007 versus 1991: 0.58 (95 per cent confidence interval 0.55 to 0.62) in men and 0.73 (0.68 to 0.78) in women). The intervention rate fell from 80.8 to 74.4 per cent in men and from 77.9 to 64.9 per cent in women. The proportion of hospital admissions as an emergency or transfer increased, from 23.9 to 40.7 per cent among men and from 30.0 to 49.5 per cent among women.
First hospital admission for PAD in Scotland declined steadily and substantially between 1991 and 2007, with an increase in the proportion that was unplanned.
本研究使用苏格兰疾病登记系统（Scottish Morbidity Record），对 1991 年至 2007 年苏格兰首次因外周动脉疾病（PAD）入院的所有病例进行了趋势分析。
首次因 PAD 入院是指因 PAD 初次入院（包括住院和日间手术），且在过去 10 年内无因 PAD 住院（主要或次要诊断）的记录。
1991 年至 2007 年，苏格兰共有 41593 人因 PAD 初次入院。其中 23016 人（55.3%）为男性（平均年龄 65.7(11.7)岁），18577 人为女性（平均年龄 70.4(12.8)岁）。无论男女，在研究期间，PAD 初次入院的人群发病率均呈下降趋势：男性从 1991-1993 年的 66.7/10 万降至 2006-2007 年的 39.7/10 万，女性分别从 43.5/10 万降至 29.1/10 万。调整后，男性发病率下降了 42%，女性下降了 27%（2007 年与 1991 年的发病率比值：男性为 0.58（95%置信区间 0.55 至 0.62），女性为 0.73（0.68 至 0.78））。男性的介入治疗率从 80.8%降至 74.4%，女性从 77.9%降至 64.9%。男性因急症或转院而入院的比例从 23.9%增至 40.7%，女性从 30.0%增至 49.5%。
1991 年至 2007 年，苏格兰因 PAD 初次入院的人数稳步大幅下降，计划外入院的比例增加。
