This study was done to see if a computerised decision tool could help GPs decide who to refer for more tests or to see a specialist. It was for people with possible symptoms of stomach or oesophageal cancer. 

The study was open for people to join between 2015 and 2017. The team published the results in 2021.

More about this trial

Many people have stomach problems such as pain, feeling full or indigestion now and then. Only a very small number of these will be caused by stomach cancer or cancer of the food pipe (oesophagus).

The GPs participating in this study used a computer aided tool. It’s called the electronic clinical decision support (eCDS) tool.

The tool collects information about symptoms and then gives a score. This score helps GPs work out someone’s risk of possibly having cancer. The researchers hoped it would help them decide which patients to refer for further tests or to a specialist.

The main aims of the study were to find out whether the computer aid can:

  • help GPs decide who to refer for further tests
  • help GPs make decisions more quickly
  • be looked at in a larger study

Summary of results

Study design
A total of 530 people from 42 GP practices joined this study. 

The GP practices taking part were put into two groups:

  • half used usual guidelines to refer people for more tests
  • half could use the electronic decision tool if they wanted to

Results
The results were similar in both groups:

  • about half the people (50%) were referred for more tests
  • about 2 out of 100 people (2%) were diagnosed with stomach or oesophageal cancer  

But the computer aided tool was not used as often as the research team would have liked.

There were problems with it which meant that many GPs chose not to use it. The issues included:

  • the eCDS tool was slow to load and to use
  • there were problems linking it to their existing computer systems
  • there were restrictions on what programmes they were allowed to use on their computers

Conclusion
The team concluded that any eCDS tool has to be easy to use and link easily to existing systems. But even then, they suggest GPs may not use a decision making tool like this very often.
