Data methodology reviewer

Peter Langdon

Peter reviews TreatCompare's approach to pricing data, source handling, normalisation, outlier checks and comparison methodology.

Role on TreatCompare

Peter's review focuses on data integrity: how TreatCompare collects prices, compares like-for-like costs, handles missing or stale data, identifies outliers and explains limitations to users. This is separate from clinical review, which should be carried out by appropriately qualified healthcare professionals for medical content.

Scope note

Data methodology review is not a clinical review, financial advice or an external audit. TreatCompare pages should still be checked against provider websites before making a decision, and medical suitability should always be discussed with an appropriate clinician.
