Before you choose the number that supports a decision, make the population, price basis, time window and source visible.
Conflicting figures are often a definition problem before they are a data problem.
You can put three credible medicines figures on one page and create the impression that only one can be true. In practice, each may describe a different population, price basis, time period or stage of the pathway. The danger begins when a team selects the most convenient number without preserving those definitions. A decision that looks precise can then rest on a comparison that was never valid. The better future is not a single perfect figure; it is a decision record that shows exactly what each figure means.
Start with the denominator, not the headline.
Before comparing values, ask who or what is counted. Is the denominator all people with a condition, those clinically eligible under a defined criterion, those currently treated, or those whose records contain enough information for review? The same discipline applies to activity and spend. National totals, local expenditure, acquisition cost, modelled resource effect and realised cash movement are different measures. Labelling them consistently removes much of the apparent disagreement before anyone debates the conclusion.
Evidence interpretation
Which definition makes these medicines figures legitimately different?
Numbers can appear to disagree because they describe different populations, prices or periods. Inspect four parts of a figure’s identity and compare strategic planning with an operational review. The model explains how to ask for a reconciliation; it does not supply a new medicines dataset or imply that unlike measures should be averaged together.

A broad estimate can guide a broad question
The planning lens may use published aggregates to understand scale or prioritise further work. It should retain the source’s geography, period and unit, rather than imply a locally verified cohort. The next decision is usually what to investigate, with more specific evidence needed before operational action.
State which local facts must be collected after the strategic estimate.
A local decision needs the matching ledger
The operational lens asks whether the organisation can verify the relevant population and cost perspective. A modelled scenario remains conditional until its inputs and authority are appropriate. Reconciliation should explain why the figures differ and allocate each to its proper question, preserving useful distinctions rather than blending them away.
Build a comparison note with a separate row for each definition.
Who or what
A count of eligible people is different from treated people, prescription items or a product pack. Before comparing figures, identify the actual denominator and exclusions. Similar labels can hide different units, and a national total may not describe the cohort a local team can act upon.
- Define the quantity
- Preserve comparability
Population definition, measurement unit and exclusions.
A useful next stepWrite the denominator in words before reading the headline value.
A number becomes more useful when its definition travels with it.
Give every number a four part identity.
A useful medicines number should travel with four things: its source, definition, effective date and decision purpose. Add the transformation history when a calculation has been applied. That small data contract lets another person reproduce the figure and decide whether it is fit for the question in front of them. It also makes updates safer. When a tariff, population estimate or policy position changes, the team can see which conclusions depend on the old input instead of rebuilding the analysis from memory.
Reconciliation should preserve difference rather than average it away.
The aim is not to force every source into one blended answer. It is to explain why the values differ and which one belongs in each decision. A national planning estimate may be appropriate for strategic capacity. A locally verified cohort may be necessary for operational work. A modelled opportunity can justify further analysis without becoming a realised saving. A good reconciliation table keeps these lanes separate and records uncertainty, exclusions and sensitivity rather than allowing a single attractive total to dominate the conversation.
The accountable question is what the number authorises.
A number can trigger investigation, support prioritisation or inform an authorised decision; those are not the same status. Teams should state the next action the figure is permitted to support and the evidence required before moving further. This is particularly important when clinical, financial and operational lenses point in different directions. Visible authority and review thresholds protect both urgency and caution: promising signals can move, while untested assumptions cannot quietly become commitments.
The evidence boundary applies to both publications.
The original commentary and this later reflection are founder views. They do not demonstrate that PHARMORIS has reconciled live institutional data, produced savings, been deployed or been adopted. What they establish is the method I expect the company to follow: define first, reconcile second and only then decide. The archived source record retains the publisher’s original byline.
