Although the frequency of cataract surgery has increased in the UK, the demand is still not being met. There is no evidence of whether Regional Health Authorities are meeting the national target of 150 cataract operations per 100,000 population. This paper describes variations in age-standardised rates of cataract surgery and lengths of hospital stay (LOS) between the 13 health districts in South West Thames Regional Health Authority (SWTRHA). A retrospective analysis of cataract surgery performed on South West Thames (SW Thames) residents during 1990 was undertaken using the Korner hospital activity data system. The residents of SW Thames Region had 6,729 cataract operations in 1990, producing an overall surgery rate of 266 per 100,000 resident population. Two-thirds of the operations were performed on women, and the greatest number of operations were in the 75-79 and 80-84 year age bands. Women aged over 75 had significantly higher age-specific surgery rates than their male counterparts. The mean age for women was 76.6 years and for men 71.9 years; 12% of cases had a length of stay less than a day (day cases) and 49% were discharged within two days. There were substantial variations in LOS between health districts. Age-adjusted rates revealed significant variations between districts, four of which had rates below the regional average. The crude cataract surgery rate for SW Thames residents has increased threefold since 1975. Women have a significantly higher rate of surgery, which may be due to social factors. Variations in LOS between districts cannot be explained by difference in age structure and may be caused by local custom and practice. It is possible for national, regional and district cataract rates to be calculated, and they are a useful indicator of how the need for cataract surgery is being met in the population.
尽管英国白内障手术的频率有所增加，但需求仍未得到满足。尚无证据表明地区卫生当局是否达到了每10万人口150例白内障手术的国家目标。本文描述了西南泰晤士河地区卫生管理局（SWTRHA）13个卫生区之间白内障手术年龄标准化率和住院时间（LOS）的差异。利用科纳医院活动数据系统对1990年在西南泰晤士河（SW Thames）地区居民中进行的白内障手术进行了回顾性分析。1990年，SW Thames地区的居民接受了6729例白内障手术，总体手术率为每10万居民人口266例。三分之二的手术是对女性进行的，手术数量最多的年龄段是75 - 79岁和80 - 84岁。75岁以上的女性特定年龄手术率显著高于男性。女性的平均年龄为76.6岁，男性为71.9岁；12%的病例住院时间少于一天（日间手术），49%的患者在两天内出院。各卫生区之间的住院时间存在很大差异。年龄调整率显示各地区之间存在显著差异，其中四个地区的比率低于区域平均水平。自1975年以来，SW Thames地区居民的白内障手术粗率增加了两倍。女性的手术率显著更高，这可能是由于社会因素。各地区之间住院时间的差异不能用年龄结构的差异来解释，可能是由当地习俗和做法造成的。计算国家、地区和地区的白内障发病率是可能的，它们是衡量人群中白内障手术需求如何得到满足的有用指标。
