Background and study aims
GPs use a technique called safety-netting to ensure their patients come back to the surgery for a follow-up appointment. This is very important when patients have symptoms that could lead to an important diagnosis such as cancer. One way to safety-net could be for the GP practice to have a computer system that highlights abnormal test results or that identifies patients who have not attended for their appointments. This study is designed to evaluate a safety-netting system that is available in general practices in England, called the E-SN toolkit.

Who can participate?
General practices who are already members of the RCGP Research and Surveillance Centre research network can take part in the study. Practices need to be using the EMIS computer system, and have data available to the research network for the past 2 years. Patients within participating practices will have data extracted as part of the study if they are over 18 years old. The researchers won’t extract data from patients who have opted out of data sharing.

What does the study involve?
The researchers recruit 60 general practices who are not currently using the E-SN toolkit, and randomly allocated them in clusters (groups) of 10. Each cluster has the E-SN toolkit turned on at a different time during the 12 months of the study. Once the E-SN toolkit is turned on, the GPs in the practice are able to use it when caring for any patient they think would benefit from it, although it is expected that it will be of most use when treating patients with symptoms that might indicate cancer. The researchers collect data from the electronic patient record system from the 12 months of the study and the 24 months before the start of the study to understand whether the introduction of the E-SN toolkit makes any difference to the diagnosis of cancer, and in particular to how quickly patients are diagnosed. The researchers only extract records from patients who are over 18, and who have not opted out of the research.

What are the possible benefits and risks of participating?
Patients may benefit from better follow up if the E-SN toolkit is used, and it is hoped that this will lead to a short time to diagnosis. If a patient with cancer has an earlier diagnosis, they may have a better chance of successful treatment. The risk of this study is very low. Using the E-SN toolkit may make GP consultations a bit longer, but this is probably only going to be by less than a minute. There is a risk of patients losing trust in the health system by becoming aware that their data is being used for research without them being asked for their consent. The researchers are hoping to reduce this by making sure that patients are aware of the study, and that they will not be identifiable from the data. They are also making sure that patients can easily opt out of sharing their data.

Where is the study run from?
The researchers carrying out the study are based at the University of Oxford and they are working with an established research network: the RCGP Research and Surveillance Centre.

When is the study starting and how long is it expected to run for?
June 2019 to October 2021

Intervention typeOther
Primary outcome measurePrimary care interval for cancer diagnoses measured as the time between the first recorded symptom of cancer and referral to secondary cancer care, during inactive and active E-SN phases
Secondary outcome measures1. Proportion of cancers diagnosed after emergency presentation measured during inactive and active E-SN phases
