Using Data and Evidence to Influence Commissioner Decision-Making

Commissioners are required to make complex decisions under time pressure, financial constraint and public scrutiny. Providers that rely on opinion rather than evidence are easily sidelined. Those that present clear, structured and credible data are far more likely to influence outcomes. This article supports Working With Commissioners, ICBs & System Partners and aligns closely with evidence expectations outlined in Quality, Safety & Governance.

What commissioners mean by β€œevidence”

Commissioners rarely expect academic research. They look for evidence that demonstrates:

  • Understanding of risk and complexity
  • Consistency between plans and delivery
  • Learning from incidents and near misses
  • Value for money without compromising safety

Blending quantitative and qualitative evidence

Effective providers combine numbers with narrative. Data without context lacks meaning, while narrative without data lacks credibility. Useful evidence includes:

  • Outcome progress summaries linked to care plans
  • Incident trends over time, not isolated events
  • Restriction reviews showing reduction efforts
  • Staffing stability and training completion data

Operational Example 1: Using trend data to counter cost pressure

Context: A commissioner proposes reducing support hours due to budget pressure.

Support approach: The provider presents trend data showing why current levels are required.

Day-to-day delivery detail: The service shares six months of incident data showing reduced frequency but increased complexity during transitions. Staff notes explain how support intensity prevents escalation and hospital admission.

How effectiveness or change is evidenced: The commissioner pauses reductions and agrees to review once further stability data is available.

Structuring evidence for commissioner consumption

Commissioners engage best with evidence that is:

  • Summarised clearly at the front
  • Linked directly to risk and outcomes
  • Available in written form after meetings

Operational Example 2: Narrative evidence supporting outcome realism

Context: A commissioner questions slow progress toward independence outcomes.

Support approach: The provider explains progress through narrative evidence.

Day-to-day delivery detail: Staff records demonstrate improved emotional regulation, reduced avoidance behaviours and increased tolerance of change. The provider explains why these steps are prerequisites to independence.

How effectiveness or change is evidenced: The commissioner agrees revised milestones aligned to the person’s current capacity.

Commissioner expectation: defensible decision-making

Commissioner expectation: Commissioners expect providers to supply evidence that allows them to justify decisions internally and externally, particularly where costs are high or risks are complex.

Regulator / Inspector expectation (e.g. CQC): evidence-led practice

Regulator / Inspector expectation: Inspectors expect providers to demonstrate how evidence informs decisions, particularly around restrictive practices and safeguarding.

Operational Example 3: Evidence preventing placement breakdown

Context: A placement is flagged as β€œhigh risk” by the commissioning panel.

Support approach: The provider submits a structured evidence pack.

Day-to-day delivery detail: The pack includes risk assessments, supervision extracts, outcome tracking and family feedback. The provider explains how risks are actively managed day to day.

How effectiveness or change is evidenced: The panel agrees continued funding, citing confidence in provider oversight.

Practical takeaway

Evidence influences decisions when it is structured, credible and clearly linked to risk and outcomes. Providers who invest in evidence systems protect both people and placements.
