Why multi-agency investigation matters
A practical guide to multi-agency investigation for NHS trusts, providers, commissioners and families. Learn the governance, evidence and delivery steps that improve outcomes and reduce risk. Strong investigations combine independence, systems thinking, meaningful engagement and practical recommendations that improve safety rather than assign blame.
The current landscape
Family and patient engagement is not optional under PSIRF. The framework makes clear that those affected by incidents should be involved in shaping the terms of reference, contributing their perspective, and receiving timely updates throughout the investigation. This requires trained family liaison, sensitivity to trauma, and genuine openness to findings that may be uncomfortable for the organisation.
The quality of an investigation report is measured not by its length, but by the clarity and actionability of its recommendations. Each recommendation should specify what needs to change, who is responsible, what the deadline is, and how progress will be measured. Vague recommendations like 'improve communication' are unhelpful and unlikely to drive real change.
What organisations need to know
This article focuses on Multi-Agency Incident Investigations: How to Coordinate Evidence and Governance and the wider priorities around multi-agency investigation, cross boundary investigation, investigation governance. The strongest organisations do not treat this as a stand-alone exercise — they connect governance, workforce, communication and evidence so leaders can make decisions quickly and confidently.
NHS trusts, providers, commissioners and families should consider these questions before proceeding:
- What governance structure will oversee the investigation and receive findings?
- Are there parallel processes (inquests, police investigations, regulatory action) that need coordination?
- How will recommendations be tracked and implemented after the report is published?
Practical checklist
Getting multi-agency investigation right requires structured preparation and disciplined follow-through:
- Set clear terms of reference, governance routes and expectations for family involvement early
- Gather evidence from records, interviews, policies and contextual operational factors
- Translate findings into recommendations with named owners, deadlines and measurable follow-through
- Translate multi-agency investigation into named actions, owners and realistic deadlines
- Keep evidence, decisions and outcomes in one place so future assurance, inspection or procurement activity is easier to manage
Evidence you should have ready
Organisations with strong evidence bases consistently perform better in independent investigations activities. Key evidence includes:
- Contextual operational data (staffing levels, workload, system pressures at the time)
- Family and patient testimony gathered with appropriate support and sensitivity
- Previous incident reports and thematic analysis to identify recurring patterns
Governance considerations
Strong governance underpins successful delivery. For multi-agency investigation, this means:
- Clear reporting lines to the commissioning organisation's board or safety committee
- A defined timeline with milestones for evidence gathering, analysis and draft reporting
Common mistakes to avoid
Based on our experience working with NHS trusts, providers, commissioners and families, these are the most frequent errors:
- Over-scoping the investigation and losing focus on the most important learning questions
- Treating family engagement as a communication task rather than a core part of the methodology
- Writing recommendations that are too vague to track or implement
Avoiding these pitfalls requires leadership commitment, clear accountability and a willingness to seek independent review when internal perspectives may be limited.
