BACKGROUND
Hospital episode statistics (HES) is a UK national database for the National Health Service (NHS), now available online. The purpose of this study was to observe trends in ophthalmic operations performed during the period from 1998 to 2004, using this data.
METHODS
From the 'Main Operation' codes within the 'Free data' section of the HES website we analysed data in regard to 28 specific ophthalmic operations. These represented each sub speciality within ophthalmology.
RESULTS
The figures show a change in the total number and proportions of operations performed for many of the procedures. For example, there was an increase in numbers of orbital decompressions, but a decrease in numbers of glaucoma filtering operations. Changing trends could be seen in different surgical areas such as the change in operations used for corneal grafting and in retinal surgery.
CONCLUSION
The HES database represents an important, potentially useful source of information. There are imitations in interpretation of and validity of such data related to coding inconsistencies. We suggest the benefit of the data comes from observing trends rather than exact numbers. As other studies using this data have suggested, it is important that clinicians are involved in improving the quality of this data.
背景
医院事件统计（HES）是英国国民医疗服务体系（NHS）的一个全国性数据库，现在可以在线获取。本研究的目的是利用这些数据观察1998年至2004年期间眼科手术的趋势。
方法
从HES网站“免费数据”部分的“主要手术”代码中，我们分析了28种特定眼科手术的数据。这些代表了眼科的各个亚专业。
结果
数据显示许多手术的总数量和比例发生了变化。例如，眼眶减压手术的数量增加了，但青光眼滤过手术的数量减少了。在不同的手术领域可以看到变化趋势，如角膜移植手术和视网膜手术所采用手术的变化。
结论
HES数据库是一个重要的、潜在有用的信息来源。在解释此类数据以及与编码不一致相关的数据有效性方面存在一些限制。我们认为这些数据的好处在于观察趋势而非精确数字。正如其他使用这些数据的研究所表明的，临床医生参与提高这些数据的质量很重要。
