The NHS DVT Waiting Time Crisis

Data obtained via Freedom of Information requests reveals how long patients wait for DVT diagnosis across NHS Trusts. Every undiagnosed DVT risks pulmonary embolism — a potentially fatal complication.

Note: Some discrepancies exist due to inconsistent data provided by NHS Trusts in response to FOI requests. We report the data as provided by each NHS Trust.
