We examined the use of asthma-related hospital services in geographically different areas of Finland in 1972-86, using data obtained from hospital discharge registers. A total of 254,402 cases diagnosed as asthma was identified (diagnosis 493, International Classification of Diseases, 8th Revision), information on the patient's place of residence enabling comparison of the southern, western, eastern, and northern parts of the country. Annual hospitalizations and the occurrence of new cases were calculated relative to the population, the former being found to increase throughout the country during the period studied, the most marked rise being 8.8% in Northern Finland (95% confidence interval 6.4-11.3%), and the smallest, 1.1%, in Western Finland (-0.2 to +2.5). A corresponding trend was also noted in the annual occurrence of new cases, which increased most in Northern Finland, i.e. by 4.8% (3.0-6.6), and decreased in Western Finland by 2.9% (-3.6 to -2.1). The change in asthma and the organization of treatment and factors related to the cold environment may, in combination, contribute to difficulties in the treatment of asthma in Northern Finland.
我们利用从医院出院登记册获得的数据，研究了1972年至1986年芬兰不同地理区域哮喘相关医院服务的使用情况。共确定了254,402例诊断为哮喘的病例（诊断编码493，《国际疾病分类》第8版），根据患者居住地信息对该国南部、西部、东部和北部进行比较。计算了相对于人口的年度住院率和新病例发生率，发现在研究期间全国范围内前者均有所增加，其中芬兰北部增幅最为显著，为8.8%（95%置信区间6.4 - 11.3%），芬兰西部增幅最小，为1.1%（-0.2至 +2.5）。新病例的年度发生率也呈现相应趋势，在芬兰北部增加最多，即增加了4.8%（3.0 - 6.6），而在芬兰西部下降了2.9%（-3.6至 -2.1）。哮喘的变化、治疗组织以及与寒冷环境相关的因素可能共同导致芬兰北部哮喘治疗困难。
