[Physicians' Opinion on Health Care in Oral Anticoagulation]

The introduction of direct oral anticoagulants (DOAC) in addition to the established Vitamin K antagonist (VKA) has increased the complexity of antithrombotic therapy leading to numerous treatment options. Studies of the medical evaluation of the current treatment situation by health care providers, which are of great importance for the development of treatment strategies in addition to studies on pharmacovigilance, are limited in the literature.

11 700 physicians (Rhineland-Palatinate, Germany) were contacted to participate in the web-based survey on health care with oral anticoagulation (OAC). After detailed quality control, the study was analysed in synopsis with routine care data of VKA patients of the thrombEVAL study programme (N = 2.011).

In total, 512 physicians (mean age: 48.0 ± 9.6 years; 74.0 % male) participated in the study. In general, quality of OAC therapy was rated as "average/satisfactory" (2.9 ± 0.9). Comparison of physicians' perception with data from routine care highlighted marked differences regarding time in therapeutic range (+ 6.4 % [95 %-CI 2.7 %; 9.5 %]), duration of control intervals (- 35.0 % [28.0 %; 41.4 %]) and rate of OAC-related complications (+ 61.8 [37.8 %; 83.3 %], which differed additionally and statistically-significant between physician groups. The willingness to use DOAC was approximately 50 % lower in general physicians as compared to specialists (36.6 % [25.4 %; 47.8 %] vs. 72.4 % [66.0 %; 78.9 %]; p < 0.0001). Regarding management of OAC therapy, 73.8 % [69.7 %; 77.9 %] advocated the establishment of a service hotline and 67.3 % [62,9 %; 71.6 %] a specialized coagulation service.

The present survey among physicians reveals a need for optimization of OAC therapy in daily practice. Specialized care models might facilitate optimized OAC therapy with both VKAs and DOACs.
