Switching from vitamin K antagonists to direct oral anticoagulants: treatment satisfaction and patient concerns

Article / Letter to editor
Background Since direct oral anticoagulants (DOACs) have been introduced for treatment and prevention of thromboembolic diseases, patients on vitamin K antagonists (VKA) have to decide whether to remain on VKA or switch to DOAC. The goal of this study was to evaluate treatment satisfaction, preferences, and concerns among those who already have switched from VKA to DOAC.Methods A questionnaire was sent to 2920 former patients of three anticoagulation clinics in the Netherlands, who switched from VKA to DOAC (2016-2017). Questions concerned demographics, treatment satisfaction, concerns, perspectives on antidotes, and monitoring. To identify predictors for being concerned about adverse events, logistic regression was used to estimate crude- and adjusted (age and sex) odds ratios (OR) and 95% confidence intervals (95% CI).Results One thousand, three hundred ninety-nine questionnaires (response rate 48%) were used for analysis. DOAC treatment satisfaction was high (mean 8.8 of a...Show moreBackground Since direct oral anticoagulants (DOACs) have been introduced for treatment and prevention of thromboembolic diseases, patients on vitamin K antagonists (VKA) have to decide whether to remain on VKA or switch to DOAC.

Questions concerned demographics, treatment satisfaction, concerns, perspectives on antidotes, and monitoring. To identify predictors for being concerned about adverse events, logistic regression was used to estimate crude- and adjusted (age and sex) odds ratios (OR) and 95% confidence intervals (95% CI).Results One thousand, three hundred ninety-nine questionnaires (response rate 48%) were used for analysis. DOAC treatment satisfaction was high (mean 8.8 of a maximum 10-point score). A quarter of patients expressed concerns about adverse events. Predictors for being concerned were age < 60 years (vs age > 75 years, OR 4.1, 95% CI 2.6-6.4), female sex (OR 1.3, 95% CI 1.0-1.6), and high education (OR 1.6, 95% CI 1.2-2.2). Fifty-nine percent of all patients indicated antidote availability as important, 73% would be willing to participate in DOAC monitoring.Conclusions DOAC treatment satisfaction was high. A substantial number of patients expressed concerns about adverse events, especially women, patients aged < 60 years, or highly educated patients. Our findings among patients who already had switched to DOAC may assist in the process of shared decision-making when switching a patient from VKA to DOAC is considered.Show less
