National Oesophago-Gastric Cancer Audit

November 2016

Thank you very much for your continued hard work in submitting data to the National Oesophago-gastric Cancer Audit. Case ascertainment for the English NHS trusts is above 80 per cent for the 2015-16 reporting period and there is still time to submit more cases before the Friday 3 February 2017 submission deadline.

The Clinical Effectiveness Unit at the Royal College of Surgeons has now conducted a preliminary analysis of the data submitted prior to the first submission deadline and would like to share its feedback.

Submission feedback

  • Data quality is of a consistently high standard and overall case ascertainment for tumour records has passed the crucial 80 per cent mark. We estimate case ascertainment for English trusts by comparing Hospital Episode Statistics (HES) to your submissions to date.
  • There is a noticeable decline in High Grade Dysplasia (HGD) submissions for the second year in a row. Please continue trying to identify all eligible HGD diagnoses. A useful flowchart about submitting HGD cases is available under Guidance on our webpage: www.digital.nhs.uk/og.
 


How does your current case ascertainment compare to previous years?

You can check your current submission figures using the Clinical Audit Platform (CAP) online reports and assess these against our evaluation of case ascertainment rates in Annex 3 of the 2016 Annual Report (keeping in mind that these contain two years' worth of submissions): www.content.digital.nhs.uk/catalogue/PUB21561.

If we suggested that your case ascertainment was relatively low in the past, but your count of eligible diagnoses is not inreasing year-on-year, then you investigate how your trust is compiling OG cases for the audit as well as for the HES dataset.

Data completeness

We need your help to ensure we have records that are both accurate and complete so as to conduct the highest quality analyses of the audit dataset.

About 20-30 per cent of non-core data forms (e.g. surgical records) still need to be uploaded. Please also check non-mandatory items that may still be empty (e.g. the date of first referral to OG service).

Using the CAP reports

A Data Completeness report is available within CAP.

Case ascertainment data is available in the Combined OG-General Status Report and you can see how many tumour records submitted to CAP have been diagnosed at your trust in the First Diagnosing Trust Count report.
