There are large variations in cataract extraction rates between different regions of England, which may indicate differences in the availability of the operation in different parts of the country. Analysis shows that there is a relationship between the availability of ophthalmic beds and operation rates, but it is not possible to determine whether the bed supply determines the operation rate or vice versa.
英格兰不同地区的白内障摘除率存在很大差异,这可能表明该国不同地区该手术的可及性存在差异。分析表明,眼科病床的可及性与手术率之间存在关联,但无法确定是病床供应决定手术率,还是反之亦然。
