Dishonesty and false records

Methodology and limits
This page analyses published erasure and voluntary-erasure determinations in the MedicWatch indexed corpus. It does not claim to measure all misconduct in UK healthcare or every regulator decision ever made.
MedicWatch applies a fixed taxonomy to regulator-derived charges, findings, and plain-English summaries. A determination can match more than one category, so category percentages may add up to more than 100%. The denominator for each percentage on this page is 105 published determinations.
Categories describe broad themes in the regulator's published findings. They are not new allegations by MedicWatch. Follow the linked source determinations for the full wording and context.
For citation, describe this as “MedicWatch analysis of its indexed corpus of published UK healthcare regulator erasure determinations”. Do not describe it as a measure of all UK healthcare misconduct.
