The National Oesophago-Gastric Cancer Audit (NOGCA) provided the surgical outcome information for the 2016 publication. The Audit was designed to look at the way NHS trusts manage patients with stomach or oesophageal cancer in England and Wales.
This website also contains the number of operations that individual surgeons have performed on patients diagnosed with stomach or oesophageal cancer between 1 April 2012 and 31 March 2015. The outcomes of these operations are also provided in terms of what proportion of patients died within 30-day and 90-days of the operation (postoperative mortality rates).
This year we collected data on 6834 patients and published outcome information on 41 specialist cancer centres (NHS trusts) and 203 consultants. Differences in the postoperative mortality rates of the cancer centres (NHS trusts) and the surgeons were examined using funnel plots. These plots are a widely used method to graphically present surgical outcomes and enable people to see whether the outcomes are within the expected range given the overall national rate.
In looking at this information, it is important to remember that the outcomes of NHS trusts and surgeons may vary because of patient factors such as the age, sex and number of other illnesses patients have – known as co-morbidities. Some surgeons might be operating on higher risk patients with complex health needs like diabetes or respiratory problems.
The results show that the 30-day and 90-day postoperative mortality rates for all NHS trusts and surgeons were within the range expected taking into account the variation in patients treated.
