Risk-based management of dental procedures in patients with inherited bleeding disorders: Development of a Dental Bleeding Risk Assessment and Treatment Tool (DeBRATT).

Introduction: Successful outcomes in dental management for patients with inherited bleeding disorders require close collaboration between haematology teams and dentists.

Aim: To review outcomes of an interdisciplinary pathway for dental procedures by assessing adequacy and appropriateness of haemostatic management.

Methods: Two hundred dental procedures in 30 patients with inherited bleeding disorders were included. A Dental Bleeding Risk Assessment and Treatment Tool (DeBRATT) was developed to identify four categories of bleeding risk (no risk, low, moderate and high risk of bleeding) in relation to the severity of the bleeding disorder and the invasiveness of dental procedure. The adequacy and appropriateness of haemostatic therapy provided in relation to the bleeding risk was assessed with reference to the published literature. Treatment was classified as appropriate, over or under-treatment. Bleeding complication was the primary outcome.

Results: A high level of dental disease was noted, with 83% of patients having at least one decayed tooth and 46.7% having chronic gum disease. A total of 59.1% of the dental procedures in patients with mild bleeding disorders were over-treated (n = 65/110) and 8.9% in patients with severe disorders had an extended duration of treatment (n = 7/79). One bleeding complication was observed in a patient with Von Willebrand's disease and severe thrombocytopenia. All other procedures (99.5%) were uneventful.

Conclusion: DeBRATT enables a risk-based approach for the management of dental procedures in patients with inherited bleeding disorders. The tool facilitates a comprehensive evaluation of bleeding risk with the potential to minimize unnecessary treatment and aid interdisciplinary communication among different clinical teams.
