RCOphth NOD National Cataract Audit Year 7 data

The data is for the sixth prospective year of the National Cataract Audit corresponding to the 2022 NHS year (01/04/2022 to 31/03/2023). The data was collected as part of routine clinical care on electronic medical record systems in 177 participating centres. The three metrics used in the national cataract audit are case ascertainment and adjusted rates for posterior capsular rupture and visual acuity loss. The denominator for case ascertainment was the number of cataract operations reported to NHS digital or Digital Health and Care Wales (DHCW) performed using phacoemulsification. Operative data is more consistent than postoperative data as not all centres use the electronic medical record systems in all areas of their hospital eye service. Postoperative results do not include operations performed in the last 2 months of the audit year or for centres with <50 eligible operations in the postoperative time period. Visual acuity estimates are only produced for centres with at least 50 eligible operations with the relevant visual acuity measurement. Comprehensive information regarding the eligibility criteria used in the National Cataract Audit can be found on the audit website (www.nodaudit.org.uk). Results are provided for contributing NHS Trusts, Welsh Health Boards, Independent Sector Treatment Centres (ISTC), one private sector provider centre and one centre from Guernsey. The results for Bradford Teaching Hospitals NHS Foundation Trust include patients from Airedale Hospital NHS Foundation Trust as cataract surgery for Airedale patients is performed in Bradford Teaching Hospitals NHS Foundation Trust sites. Results for Moorfields Eye Hospital NHS Foundation Trust include data for patients treated in Bedford Hospital from the Bedfordshire Hospitals NHS Foundation Trust and data for patients treated in the Croydon Health Services NHS Trust.

本数据集对应于2022年度国家白内障审计的第六个前瞻性年度，涵盖国家卫生服务体系(NHS)2022年度（2022年4月1日至2023年3月31日）。数据收集系作为常规临床护理的一部分，在177个参与中心利用电子病历系统进行。国家白内障审计所采用的三个指标为病例识别及调整后的后囊膜破裂和视力丧失发生率。病例识别的分母为向国家卫生数字部门或威尔士数字健康与护理部门（DHCW）报告的采用超声乳化术进行的白内障手术数量。由于并非所有中心在其医院眼科服务的所有领域都使用电子病历系统，因此手术数据的一致性高于术后数据。术后结果不包括审计年度最后两个月进行的手术或术后时间段内符合条件手术数量少于50例的中心的数据。仅对至少有50例符合条件手术并进行相关视力测量标准的中心产生视力估计。关于国家白内障审计所使用的资格标准，可在审计网站（www.nodaudit.org.uk）上找到详细信息。结果提供给了贡献国家卫生信托基金、威尔士卫生委员会、独立治疗中心（ISTC）、一个私营部门提供中心以及根西岛的一个中心。布拉德福德教学医院国家卫生信托基金的结果包括埃尔德雷尔医院国家卫生信托基金的患者，因为埃尔德雷尔医院的白内障手术是在布拉德福德教学医院国家卫生信托基金场所进行的。莫尔菲尔德眼科医院国家卫生信托基金的结果包括来自贝德福德医院的国家卫生信托基金的患者数据，以及来自克罗伊登健康服务国家卫生信托基金的患者数据。
