The project hub is designed to help you quickly obtain the resources necessary to undertake the STARSurg project. 

DiSCOVER Key Facts

A mini-team of two medical students and a doctor will collaborate at each participating centre to prospectively collect data over a multiple 14-day periods on consecutive patients undergoing gastrointestinal or hepatobiliary surgery, with 30 days of follow-up.

The National Institute for Health and Care Excellence (NICE) recommend that all patients undergo calculation of body-mass index (BMI) upon admission to hospital.

The primary objectives are:

1. to establish compliance with NICE guidelines requiring early identification of obese patients

2. to determine whether obesity is associated with an excess risk of major post-operative complications. To answer this question, both obese and non-obese patients will be included, with adequate data collected to provide accurate risk adjustment.

DISCOVER eLearning

This brief guide will outline how to access the eLearning module for the STARSurg DiSCOVER Project, completing the module will equip you with the knowledge to apply the protocol and ensure optimal data quality.

1. To undertake the Clavien-Dindo eLearning module, go to “”

2. Create an account.

3. Once you have created an account, search for the quiz “DISCOVER Study” under classes using the exact match search. Click the checkbox and click register/enrol.

4. Carefully read the onscreen instructions to undertake the module. You have a maximum of 10 attempts to achieve a 100% grade. Click submit at the bottom of each page to navigate through the screens.

Once you have completed the module, you are ready to undertake the STARSurg DISCOVER project!

Key Steps to DISCOVER Success

We present below a few key steps to making DISCOVER a success at your centre.

1. Ensure that audit registration is confirmed at your site.

2. Read the protocol including its annexes in full. These documents contain all the details you need to know to ensure you are collecting and reporting accurate data.

3. Pass the E-Learning module with flying colours. This will ensure a high accuracy and quality dataset.

4. Get geared up to collect and enter data. Ensure you have access to REDCap at least 24 hours before project kick-off. You may use paper forms or Excel sheets first to collect data before transferring them onto REDCap. This should be kept securely. We have released Annex G of the protocol which provides step-by-step guidance.

5. Create an Excel file which will link REDCap Study IDs to NHS IDs. This again should be saved on NHS computers and needs to be done only if no explicit permission has been obtained to store NHS IDs on REDCap.

6. Create a DISCOVER Study Site File. This can contain hard-copies of full protocol, paper forms, and excel sheets (patient lists)- all essentials for a successful audit. Your junior doctor in the team will be able to advise you on the best place to keep this. Alternatively you may have an e-version of this on a secure NHS computer.

7. Run a pilot day before the official kick-off. Familiarise yourself with the sources of the data you require- the online data system, case notes, etc. This ensures that you hit the ground running from Day 1.

8. Collect data prospectively and proactively. A key quality aspect of the dataset is its prospective nature. Ensure that your dataset is collected as timely and as accurate as possible. Proactively check for complications from a variety of sources frequently- this will include online patient management systems, written medical notes and clinical letters.

9. Complete follow-up by telephone interviews to patients and their GPs if and only if this is routine local practice. Otherwise patient follow-up using online management systems, written medical notes and clinical letters is sufficient and perfectly acceptable.
