For Researchers

Health Wise Wales (HWW) has a register of 20,000+ participants that are ready to take part in research studies.

HWW aims to recruit at least 100,000 individuals living in Wales between 2015-2020. These participants are also members of a cohort with longitudinal data on health and lifestyle factors and record-linked to routinely available healthcare data in Wales.

There are a number of different ways HWW can support your research data collection:

  1. HWW can email all participants/targeted participants about your study to promote recruitment.
  2. Researchers can access data held in the HWW data repository, which can include routine healthcare data that is available in the Secure Anonymised Information Linkage (SAIL) databank;
  3. HWW can support data collection for your study by hosting questionnaire modules on the HWW Platform and linking participant data to healthcare records (SAIL);

The HWW research Platform was set up to support a broad range of health and social care research. All research needs to fit with the ethos and the following research themes:

  • Impact of social inequalities on health and wellbeing
  • Environment, neighbourhood and health
  • Maintenance of health and wellbeing in the working age population
  • Wellbeing in later life
  • Innovation in health and social care services

We are particularly keen to receive proposals that have a focus on:

  • Cancer
  • Mental Health
  • Dementia
  • Pregnancy
  • Early childhood health and development
  • The HealthWise Wales Resource

    HWW has three components: People, Platform and Portal. HWW People comprise the HWW team at Cardiff University, Swansea University (SAIL and UKSeRP), Health and Care Research Wales and Patient and Public Involvement (PPI). The most important people who contribute significantly to the HWW resource are the 20,000+ participants. The HWW team are available to advise and assist you to decide which aspects of the HWW resource are appropriate to your research idea and to guide you through the application process.

    The Platform is the survey’s virtual online interface comprising the HWW Website and Web Application (data collection tool). The Platform hosts both researcher led questionnaire modules and core HWW questionnaire modules. Both types of questionnaire data can be linked to the participants’ routinely collected healthcare data. The data collected from HWW participants are exported via SAIL for matching with routinely collected healthcare data and stored on the Secure Analysis Portal and Protected HealthWise Wales Information Repository (SAPPHIRe), which is implemented on the UK Secure eResearch Platform (UKSeRP). All data are accessed and analysed via SAPPHIRe.

  • Public and Patient Involvement (PPI)

    HWW is about creating a partnership between researchers and the public, where everyone can be an active and equal contributor. PPI is an important component of every aspect of HWW and we aim to involve members of the public in consultation and in collaboration with the project management of HWW. Therefore, members of the public will be involved in scrutinising your research proposal.

  • FAQs

    What data is already available in HWW?

    HWW collects data directly using web-based questionnaires (core-modules). The data available include information collected from HWW participants from core questionnaire modules, researcher-led modules (except where the researchers have requested time limited exclusive use of these data) and linked routinely collected healthcare data.

    The data dictionary is available upon request and includes details on the data currently collected. Data that are currently being collected or going through the preparation process will be listed with dates of future availability. Any questions related to HWW data will be dealt with by the HWW project team.

    How long does the process take from idea conception to data access?

    There are a number of processes as outlined in the flow diagram that must be completed before data can be accessed. Once the questionnaire has been released to the online Platform it will be available to HWW participants for six months. Data collected from the questionnaire will be made available via SAPPHIRe as soon as data collection for that module has been cleaned, catalogued and released.

    Currently, data are extracted every 10,000 recruits, but special arrangements can be made according to the needs of researchers who submit questionnaire modules e.g. some modules may be active for a certain time period to provide data for a specific follow-on grant cycle; other module data may be restricted to the researcher for a specified time period before being released for wider use. Depending on the complexity of the dataset, extracts take four to six weeks to process.

    Do I have sole access to the data I collect on the website?

    Upon request, data generated from researcher led questionnaires can be made exclusively available to the applicant for a period of up to 12 months. After this, the data will be made available to all researchers as part of the suite of HWW datasets.

    How can I access HWW data?

    Subject to data user verification, a data access agreement, and physical and procedural controls, data users are assigned a time-limited account to access their data view remotely via SAPPHIRe. System safeguards include a fire-walled Virtual Private Network (VPN), enhanced user authentication, auditing of all SQL commands, and configuration controls to ensure that data cannot be removed or transferred unless authorised.

    Does HWW have ethical approval?

    HWW has been reviewed and approved by the Wales Research Ethics Committee 3 (reference 15/WA0076). If you are submitting a new questionnaire, for upload as a questionnaire module on the HHW Platform, the HWW team will need to apply for ethical approval as a substantial amendment and Information Systems (IS) development will not begin until approval has been obtained.

    Do I need ehthical approval for my study?

    Yes. You must ensure you have/ are obtaining the relevant ethics approvals, PPI and Research & Development (R&D) approvals for your study. In addition, if HWW is uploading questionnaire modules this requires a substantial amendment to the on-going HWW ethical approval.

    What will it cost to use HWW?

    The cost for using HWW will be determined on a case-by-case basis depending on the complexity of the proposed project. This will be negotiated with the HWW team during development of the application. It is the responsibility of the researcher to ensure funding is in place to complete the research using HWW data. You may wish to talk to us when developing your funding bid. We will be able to discuss costs with you and suggest how to integrate these into your research application.

    Will I need to acknowledge HWW in my research publications?

    We request that you acknowledge HealthWise Wales in any publications resulting from this collaboration. All researchers using HWW will be provided with standard text for the acknowledgement.

    How do I apply to use the HWW resource?

    Please see the Application Process section for how to apply to work with HWW.

  • Example of projects supported by the HWW Platform

    HWW has already supported a number of researchers to launch researcher led questionnaires on the HWW Platform. For example:

    Skin Cancer Awareness:

    To assess skin cancer knowledge, preventative behaviour and knowledge of Vitamin D in a sample of the Welsh population. HWW enabled the study team to assess how effective the current skin cancer prevention campaigns are in Wales.

    Oral Health:

    To understand oral health behaviours (e.g. toothbrushing, pattern of dental service access etc) of children. This module is directed to the parents of children aged 2-6 years.

    Using the HWW Platform has allowed the researchers to quickly access a large group of varied participants who are already engaged with research. This has enabled efficient and cost-effective data generation that can be linked to the SAIL databank.

    HWW has also supported a number of studies with recruitment to their online surveys. These include the Heath and Senses study from Cardiff University’s School of Psychology and the Public Attitudes to Death and Dying survey from The Marie Curie Palliative Care Research Centre. Advertising these studies to HWW participants led to an instant increase in awareness of the research and the number of participants completing the surveys.
