The 2019 surgical outcome information was provided by the National Oesophago-Gastric Cancer Audit (NOGCA). The audit was designed to look at the way NHS trusts manage patients with stomach or oesophageal cancer in England and Wales.
This website contains the number of operations performed on patients diagnosed with stomach or oesophageal cancer in English specialist cancer centres, and by individual surgeons. The outcomes of these operations are also described in terms of what proportion of patients died within 30 days and 90 days of the operation (postoperative mortality rates).
The information for English NHS organisations was produced from patients diagnosed between 1 April 2015 and 31 March 2018. For the individual surgeons, the information was produced from the five years between 1 April 2013 and 31 March 2018. The longer time period made the statistics more robust because it was produced from a greater number of patients.
This year, we publish outcome information on 35 specialist cancer centres (NHS trusts) and over 150 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 illustrate how the mortality rates are expected to vary between organisations and surgeons given the influence of random variation. Using these plots 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 differences in patient factors such as their age, sex and the 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.
