The aim of this study was to assess the impact of the pollution caused by the aluminium sulphate emptied into the water at the Lowermoor Treatment Works on the standardized hospital discharge ratios in the Camelford area, Cornwall.
Comparisons were made between the Camelford area and other localities in Cornwall of standardized hospital discharge ratios up to five years following the pollution incident. The diagnoses of discharges were defined by ICD 9 code and grouped in chapters. The figures for Camelford were compared with those for Cornwall.
Since the pollution incident, the standardized discharge ratio has increased in the Camelford area compared with Cornwall. No similar increase was observed in other localities of Cornwall. No one diagnosis was found to cause this increase.
The pollution of the water to the people of Camelford has raised hospital discharges. Monitoring of hospital discharges will continue.
本研究的目的是评估在康沃尔郡卡梅尔福德地区的洛莫尔污水处理厂排入水中的硫酸铝所造成的污染对标准化医院出院率的影响。
对污染事件发生后长达五年的卡梅尔福德地区与康沃尔郡其他地区的标准化医院出院率进行比较。出院诊断按照国际疾病分类第九版（ICD 9）编码进行定义，并按章节分组。将卡梅尔福德的数字与康沃尔郡的数字进行比较。
自污染事件以来，与康沃尔郡相比，卡梅尔福德地区的标准化出院率有所上升。在康沃尔郡的其他地区未观察到类似的上升情况。未发现单一诊断导致这种上升。
水污染对卡梅尔福德地区居民造成影响，导致医院出院人数增加。将继续监测医院出院情况。
