Good access to health services may be important for effective asthma management amongst patients, thus preventing unnecessary deaths. In a previous study, we found elevated levels of asthma mortality in English local authority districts with poor access to acute hospitals. Here, the relationship between asthma mortality and access to primary and secondary services within the rural region of East Anglia is examined.
A geographically based descriptive study, within 536 electoral wards in the region of East Anglia, England. Regression analysis was used to examine the relationship between health service accessibility, and mortality from asthma during the period January 1985 to December 1995.
After controlling for confounding factors, there was a significant tendency for asthma mortality to increase with travel time to hospital, with a relative risk of 1.07 for each 10-minute increase in journey time (P = 0.04). There was no consistent trend for mortality to increase with travel time to general practitioner surgeries.
The results of this study support the conclusions of earlier work that inaccessibility of acute hospital services may increase the risk of asthma mortality. The provision of good access to these facilities may be one factor in reducing the burden of avoidable deaths from asthma.
良好的医疗服务可及性对于患者有效管理哮喘可能至关重要,从而预防不必要的死亡。在之前的一项研究中,我们发现,在难以获得急性医院服务的英国地方当局辖区,哮喘死亡率有所上升。在此,我们考察了东安格利亚农村地区哮喘死亡率与获得初级和二级医疗服务之间的关系。
在英国东安格利亚地区的536个选区进行一项基于地理信息的描述性研究。采用回归分析考察1985年1月至1995年12月期间医疗服务可及性与哮喘死亡率之间的关系。
在控制混杂因素后,哮喘死亡率有随前往医院的时间增加而显著上升的趋势,行程时间每增加10分钟,相对风险为1.07(P = 0.04)。死亡率随前往全科医生诊所的时间增加并无一致趋势。
本研究结果支持早期研究的结论,即难以获得急性医院服务可能增加哮喘死亡风险。提供良好的这些设施可及性可能是减轻哮喘可避免死亡负担的一个因素。
