Hospital-Based Youth Work Evaluation FAQs

We are using data (information) from CYP who presented at a London hospital (A&E or Major Trauma Centres) with injuries or mental health issues as a result of violence between 2007 and June 2024.

CYP must have been between 11-25 years old when they went to the hospital. If you fulfil these criteria, we may be using your data.

We are not using everyone’s data. This is because it depends on when the hospital you attended started offering the HBYW service to young people.

We are using data from the NHS (health data from the government). We are also asking the organisations who deliver the HBYW programme (Oasis, Redthread/Catch22 and St Giles Trust), called service providers, to share data with us to identify the CYP who used the service. 

We are using the following personal information: 

• Demographics: name, age, borough, gender, ethnicity. 

• Hospital related information: date of attendance to the hospital, reason for attendance to the hospital, safeguarding flags. 

We need all the data we're using to do the evaluation. We're not collecting any data that will not be used for the project.

The data will be shared and used in the following ways:

1. To identify the CYP who have benefited from the HBYW programme: To do this, the HBYW service providers will share the names of CYP who engaged with the service and when they attended hospital with us, so we can find these CYP in the NHS data.  

2. To answer our research questions: We will compare the outcomes for the different groups of CYP we have identified – those who have engaged with the service, those who did not engage but attended the hospital at a time when the service was being delivered, and those who attended the hospital before the service was offered. This allows us to know if the programme has any effect in reducing the likelihood of these young people being affected by violence. 

We cannot contact the people that attended the hospital in the past to ask them if they want to be included in the evaluation. It would not be feasible and we do not have their contact details.

For this reason, we are relying on “Public Task” as a lawful basis for processing the data under UK GDPR. This means we are allowed to use your data for the evaluation as it is for the public good.

We are seeking approval from the Health Research Authority and NHS Confidentiality Advisory Group to grant Section 251 support for the activity. This notice will be updated once support is granted. 

The research team at  the Behavioural Insights Team have put many measures in place to handle your data securely. All the data will be looked at and handled in secure environments protected to the highest standards. Only the research team can look at your data. The NHS has reviewed how we go about keeping your data safe.  

Data will be pseudonymised as early as possible. This means that after we have identified the different groups of CYP using names, the research team will replace your information with meaningless codes. No-one will be able to tell if a specific person is part of the research. 

The research team will seek to use the NHS Secure Data Environment to analyse your data if that is deemed feasible.​ It may also be analysed on BIT’s internal computer systems, which is protected to very high standards (ISO 27001 certification). 

If you don’t want your data from the NHS to be used as part of this study, you need to complete the National Data Opt-Out online. If you are under 13, your parent or guardian needs to complete it for you.

Once we have your data, the National Data Opt-Out will only be valid for future studies. This means we will still use your data for this evaluation.

If we're able to identify you in the data when we get your request, we will delete it and not use it for the evaluation.

If your data is already pseudonymised (meaning it’s not linked to your name and other information that allows us to identify you) we will not be able to delete it.

The research team will be very happy to answer any questions.
