Co-designing and testing the learn together guidance to support patient and family involvement in patient safety investigations: a mixed-methods study.

Background: There are multiple reasons for involving patients and families in incident investigations. Fiscally, costs due to clinical negligence claims approximate £4 billion annually. Logically, patients and families provide important information about patient safety incidents. Morally, involving harmed patients and families helps address their concerns. However, little United Kingdom-based evidence was available to support systematic involvement.

Objective: To co-design processes and resources to guide the involvement of patients and families in incident investigations at a national and local level, and to test these processes to understand their impact upon experience, learning and likelihood of litigation.

Design and methods: A mixed-methods programme of research was undertaken. Stage 1 comprised a scoping review of evidence for the experience of patients/families in incident investigations, and a documentary analysis of 43 National Health Service Trust incident investigation policies. Stage 2A extended this with 41 qualitative interviews with patients/families, healthcare staff and investigators. Stage 2B synthesised previous data to develop common principles and programme theory. Stage 3 involved a 6-month co-design phase with a 'co-design community' of > 50 stakeholders. In stages 4 and 5, co-designed guidance was evaluated in a 15-month ethnography, within four National Health Service Trusts and the national independent investigatory body. Twenty-nine investigations were followed in real time, including 127 interviews and 45 hours of observation. Four final co-design workshops supported iterations to the final guidance and website. A substudy explored meaningful involvement in, and learning from, investigations following suicide via interviews and a qualitative survey involving 32 people (healthcare staff, policy-makers and managers; people bereaved by suicide).

Findings: Stage 1 found stakeholders valued involvement, but it was not well supported by local policy, even though it likely reduces litigation. Stage 2A found a need for navigational support, and support for other needs. In stage 2B, 10 common principles and a programme theory were developed, emphasising the aim of reducing compounded harm, alongside promoting organisational learning. In stage 3, four draft guidance booklets and a training session were developed. Stage 4 found these to be feasible, with stakeholders positive about involvement, and generally agreed that it aided organisational learning. The guidance supported systematisation of involvement and encouraged relational working, but wider organisational challenges were highlighted. The substudy found that suicide was regarded as somewhat different to other safety events. Meaningful involvement was complicated by a range of factors and should be decoupled from postvention support.

Limitations: Undertaking research during the pandemic may have impacted sample representativeness in stage 2A. Ethnically minoritised and lower socioeconomic groups were under-represented across the programme.

Future research: Research should explore how people from minoritised groups experience investigations and any required adaptations to the approach. Research should also explore the possibilities for 'harm-centred' rather than 'incident-centred' responses to safety.

Conclusions: Investigations are complex, relational processes. Our guidance was found to be feasible, with stakeholders being positive about involvement and the impact on organisational learning. It may help to reduce the significant and long-lasting experience of compounded harm for patients and families. However, involvement may always be challenging due to the divergent needs of patients/families and organisations.
