A Risk Score for Bleeding with Anticoagulant Use

The new QBleed score derived from U.K. primary-care data calculates risks for upper gastrointestinal bleeding and intracranial bleeding.

Bleeding — particularly upper gastrointestinal bleeding (UGIB) and intracranial bleeding (ICB) — is a potential complication of anticoagulant use. Several attempts have been made to develop a scoring system to quantify the risk factors for bleeding. A new score developed in the U.K. (QBleed) estimates absolute risk for UGIB or ICB in new users of anticoagulants.

Using a U.K. general-practice database linked to hospital and mortality data, investigators identified a cohort of 4.4 million patients for use in developing the QBleed score and a cohort of 1.4 million different patients for validating it. Potential risk factors were entered into the database prospectively, including the Townsend score for socioeconomic status. The individual variab…
