National Bowel Cancer Audit 2014

Making clinical audit data transparent

In his transparency and open data letter to Cabinet Ministers on 7 July 2011, the Prime Minister made a commitment to make clinical audit data available from the national audits within the National Clinical Audit and Patient Outcomes Programme.

The information available from this webpage comes from the National Bowel Cancer Audit. The Audit covers Strategic Clinical Networks and NHS Trusts in England and Wales.

What information is being made available?
 Audit participation by NHS Trust and data completeness for the key fields
 Measures about the process of care given to patients
 Information about care outcomes and treatment.
These data do not list individual patient information nor do they contain any patient identifiable data.

Using and interpreting the data

Data from the National Bowel Cancer Audit requires careful interpretation, and the information should not be looked at in isolation when assessing standards of care.

Data are provided by place of surgery in secondary care for the period 1 April 2012 to 31 March 2013. As a result, some trusts that only provide some specialist treatments for patients and do not supply surgical data are not fully represented in these data. We estimate the number of patients diagnosed at each trust from the Hospital Episode Statistics database and that number provides the ‘denominator' for the case ascertainment. It is much more difficult to define a population denominator for specialist centres because patients treated there have often been diagnosed elsewhere, and the treatment they provide is usually only one part of a complex care pathway. Therefore their performance should not be assessed from the results as published here. These trusts do however fully participate in the audit by providing treatment data for the referring trusts.

Accessing the data

The data are being made available on the data.gov website. Each year files of data from the National Bowel Cancer Audit will be made available in CSV format. Trusts and Networks are identified by name and their national code.

What does the data cover?

The data measure levels of completeness for data submitted to the National Bowel Cancer Audit and measures of performance in the audit at trust level for key performance measures for assessing standards of care for bowel cancer in secondary care. Details of these standards can be found in the appendices of the National Bowel Cancer Audit Report 2014.

Are all Trusts included?

All Trusts in England that manage patients diagnosed with bowel cancer are included.

What period does the data cover?

This data covers patients with a date of diagnosis between 1 April 2012 and 31 March 2013.

于2011年7月7日致内阁部长的透明度与开放数据信函中，首相承诺将国家临床审计与患者结局计划内的国家临床审计数据予以公开。本网页提供的信息源自国家结直肠癌审计。该审计涵盖英格兰和威尔士的战略临床网络及国家卫生服务信托机构。

公开信息包括：
 国家卫生服务信托机构的审计参与度及关键字段的资料完整性
 关于对患者提供的护理过程的指标
 关于护理结果和治疗的信息。
这些数据不包含任何个人患者信息，也不包含任何可识别患者的数据。

数据的使用与解读：
国家结直肠癌审计的数据需要谨慎解读，在评估护理标准时，不应孤立地看待这些信息。
数据由二级护理的手术地点提供，时间范围为2012年4月1日至2013年3月31日。因此，仅提供部分专科治疗且不提供手术数据的信托机构在这些数据中并未得到全面体现。我们根据医院病例统计数据库估计了每个信托机构诊断的患者数量，该数量作为病例确定的分母。定义专科中心的人口分母更为困难，因为在该中心接受治疗的患者通常在其他地方被诊断，且他们提供的是复杂护理途径的一部分。因此，不应根据此处发布的结果评估其表现。然而，这些信托机构通过为转诊信托机构提供治疗数据而全面参与了审计。

数据获取：
数据在data.gov网站上提供。每年，国家结直肠癌审计的数据将以CSV格式提供。信托机构和网络通过名称和国家级代码进行标识。

数据覆盖范围：
数据衡量了提交给国家结直肠癌审计的数据的完整性水平，以及在国家卫生服务信托机构层面的审计关键绩效指标，以评估二级护理中结直肠癌的护理标准。这些标准的详细信息可在国家结直肠癌审计报告2014年的附录中找到。

是否所有信托机构均包括在内？
所有管理结直肠癌诊断患者的英格兰信托机构均包括在内。
数据覆盖的时期：
此数据涵盖诊断日期在2012年4月1日至2013年3月31日之间的患者。
