      <title>Objective and Approach</title>
      <p>Research on social care services requires large, comprehensive, routine datasets. Launched in November 2019, Developing resources And minimum data set for Care Homes’ Adoption (DACHA) study aims to develop a prototype minimum dataset as proof of concept and to propose implementation.</p>
      <p>We describe our experience since 2021 of identifying, applying for, and linking care home, local, integrated care system (ICS) and national datasets, including direct-care software-provider data, GP and NHS England (NHSE) datasets.</p>
    </sec>

      <title>Results</title>
      <p>Our key challenges:</p>
      <list list-type="order">
        <list-item>
          <p>Risk aversion and fragmented information governance within and between organisations.</p>
        </list-item>
        <list-item>
          <p>Complex information governance structures must be understood before participants are recruited.</p>
        </list-item>
        <list-item>
          <p>Shifts in the data landscape: data ownership moved from clinical commissioning groups to ICSs; NHSE merged with NHS Digital.</p>
        </list-item>
        <list-item>
          <p>Research funding: research is required of ICSs, but it is not a system priority, so processes and funding aren’t in place, and research burdens an already strained system.</p>
        </list-item>
      </list>
      <p>Our key lessons:</p>
      <list list-type="order">
        <list-item>
          <p>Formalising agreements early on and obtaining, and maintaining, senior, committed buy-in.</p>
        </list-item>
        <list-item>
          <p>Studies should value the data sharing process through the inclusion of data controllers and information governance staff in the system in research project budgets.</p>

      <title>Implications</title>
      <p>The DACHA study overlapped with the COVID-19 pandemic and could only engage a limited number (n=3) of ICSs within project resources. Nevertheless, the complexity of the system and the plurality of actors delay or even block legitimate research interests.</p>
