Post‐procedural bleeding rate and haemostatic treatment use for dental procedures before and after the implementation of a standardized protocol for people with inherited bleeding disorders.

Introduction: Persons with inherited bleeding disorders are at a substantial risk of bleeding following dental procedures. Aim: To compare the outcomes and use of haemostatic treatment pre‐ and post‐implementation of a standardized protocol for dental procedures at a Hemophilia Treatment Centre. Methods: We conducted a retrospective cohort study of outpatient and inpatient dental procedures and maxillofacial surgeries sustained by people with bleeding disorders treated at a comprehensive Hemophilia Treatment Centre (2013‐2020), comparing patients' outcomes before and after the introduction of the protocol in 2018. The protocol, built using a multidisciplinary approach, suggested haemostatic treatment based on the invasiveness of the dental procedure and the proposed anaesthesia. Our primary outcome was the rate of procedural bleeding leading to medical or dental reintervention within 10 days. Secondary outcomes included the use of systemic haemostatic treatment and treatment‐related adverse effects. Results: Overall, 137 dental procedures in 95 patients (median age: 29 years; 78% males; 74% haemophilia, 14% von Willebrand disease, 12% other disorders) were included. Seventeen procedural bleedings were reported (12.4%). Procedural bleeding occurred in 14.8% and 8.9% of patients in the control and intervention groups (p =.304). No major bleeding occurred. Tranexamic acid was used more consistently after protocol implementation (72.8% vs. 89.3%, p =.019), while factor concentrates use decreased (65.4% vs. 44.6%, p =.016), and desmopressin use remained constant (46.4% vs. 32.1%, p =.100). No treatment‐related adverse effects were reported. Conclusion: The use of a standardized protocol increased the use of tranexamic acid, with a nonstatistically significant reduction in procedural bleeding rate. [ABSTRACT FROM AUTHOR]
