Rekk K, Arnet I, Dietrich F, Polymeris AA, Lyrer PA, Engelter ST, Schaedelin S, Allemann SS. Relationship between electronically monitored adherence to direct oral anticoagulants and ischemic or hemorrhagic events after an initial ischemic stroke-A case control study. PLoS One 2024; 19:e0301421. [PMID: 38662779 PMCID: PMC11045050 DOI: 10.1371/journal.pone.0301421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 03/15/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Patients with atrial fibrillation (AF) have a high risk for recurrent clinical events after an ischemic stroke. Direct oral anticoagulants (DOAC) are prescribed for secondary prevention. Adherence to DOAC is crucial mainly because of their short elimination half-life. Non-adherence to DOAC can negatively impact patients' outcomes. The relationship between (non-)adherence and recurrent clinical events is unknown in AF patients after initial stroke. We investigated adherence to DOAC in stroke survivors with AF who were included in the MAAESTRO study at the University Hospital Basel, Switzerland, between 2008 and 2022. METHODS This study is a secondary analysis of data from MAAESTRO with a matched nested case-control design and 1:2 ratio. DOAC intake was measured with a small electronic device (Time4MedTM). We defined two arbitrary intervals of 17 days and 95 days as the longest time spans with electronic monitoring data per patient to maximize the number of participants with adequate amount of observation time available for analysis. Taking and timing adherence were calculated retrospectively i.e., prior to the recurrent event for cases. Trendline analysis of adherence over 95 days was calculated. Linear regression analysis was performed after adjusting for the co-variables age and daily pill burden. Sensitivity analysis was performed with controls for intervals in the reverse direction (prospectively). RESULTS We analyzed 11 cases and 22 matched controls (mean age: 75.9 ± 9.2 years vs. 73.1 ± 8.4 years; n.s.) with similar stroke characteristics (NIHSS, mRS, MoCA) and 36.4% women in each group. Mean adherence values were high and similar between cases and controls (95 days taking: 87.0 ± 18.9% (cases) vs. 90.8 ± 9.8% (controls), n.s.; similar values for timing adherence). Six hemorrhagic and five ischemic events had occurred. Compared to controls, a significantly higher 95 days taking adherence was observed for hemorrhagic events (96.0 ± 5.0% (cases) vs. 88.1 ± 11.5% (controls); p<0.01) and a significantly lower 95 days taking adherence was observed for ischemic events (75.7 ± 24.8% (cases) vs. 94.2 ± 6.2% (controls), p = 0.024). Values for timing adherence were similar. A non-significant downward linear trend of adherence was observed over 95 days independently of the clinical events. The sensitivity analysis showed that the direction of the interval had negligible impact on the 95 days adherence. CONCLUSION Because recurrent ischemic events after an AF-related stroke were associated with low adherence to DOAC <76%, adherence enhancing interventions seem crucial in anticoagulated AF-patients. However, AF-patients with high adherence might benefit from a regular re-assessment of the bleeding risk as hemorrhagic complications were associated with adherence to DOAC >96%.

Abstract
BACKGROUND Direct oral anticoagulants (DOAC) effectively prevent recurrent ischaemic events in atrial fibrillation (AF) patients with recent stroke. However, excellent adherence to DOAC is mandatory to guarantee sufficient anticoagulation as the effect quickly subsides. AIM To investigate the effect of intake reminders on adherence to DOAC. METHODS MAAESTRO was a randomised, cross-over study in DOAC-treated AF patients hospitalised for ischaemic stroke. Adherence was measured by electronic monitoring for 12 months. After an observational phase, patients were randomised to obtain an intake reminder either in the first or the second half of the subsequent 6-month interventional phase. The primary outcome was 100%-timing adherence. Secondary outcomes were 100%-taking adherence, and overall timing and taking adherence. We analysed adherence outcomes using McNemar's test or mixed-effects logistic models. RESULTS Between January 2018 and March 2022, 130 stroke patients were included, of whom 42 dropped out before randomisation. Analysis was performed with 84 patients (mean age: 76.5 years, 39.3% women). A 100%-timing adherence was observed in 10 patients who were using the reminder, and in zero patients without reminder (p = 0.002). The reminder significantly improved adherence to DOAC, with study participants having 2.7-fold increased odds to achieve an alternative threshold of 90%-timing adherence (OR 2.65; 95% CI 1.05-6.69; p = 0.039). A similar effect was observed for 90%-taking adherence (OR 3.06; 95% CI 1.20-7.80; p = 0.019). Overall timing and taking adherence increased significantly when using the reminder (OR 1.70; 95% CI 1.55-1.86, p < 0.01; and OR 1.67; 95% CI 1.52-1.84; p < 0.01). CONCLUSION Intake reminders increased adherence to DOAC in patients with stroke attributable to atrial fibrillation. TRIAL REGISTRATION ClinicalTrials.gov: NCT03344146.

Abstract
It is well established that direct oral anticoagulants (DOACs) are the cornerstone of anticoagulant strategy in atrial fibrillation (AF) and venous thromboembolism (VTE) and should be preferred over vitamin K antagonists (VKAs) since they are superior or non-inferior to VKAs in reducing thromboembolic risk and are associated with a lower risk of intracranial hemorrhage (IH). In addition, many factors, such as fewer pharmacokinetic interactions and less need for monitoring, contribute to the favor of this therapeutic strategy. Although DOACs represent a more suitable option, several issues should be considered in clinical practice, including drug-drug interactions (DDIs), switching to other antithrombotic therapies, preprocedural and postprocedural periods, and the use in patients with chronic renal and liver failure and in those with cancer. Furthermore, adherence to DOACs appears to remain suboptimal. This narrative review aims to provide a practical guide for DOAC prescription and address challenging scenarios.

Impact of the COVID-19 lockdown on the adherence of stroke patients to direct oral anticoagulants: a secondary analysis from the MAAESTRO study. J Neurol 2022; 269:19-25. [PMID: 34081196 PMCID: PMC8173508 DOI: 10.1007/s00415-021-10631-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 05/25/2021] [Accepted: 05/27/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND The negative impact of the COVID-19 outbreak on stroke care has been reported, but no data exist on the influence of the lockdown on medication adherence to antithrombotic treatment for stroke prevention. We present a comparison of electronic adherence data of stroke patients treated with direct oral anticoagulants (DOAC) prior to and during the COVID-19 lockdown in spring 2020 in Switzerland. METHODS This is a secondary analysis using data from the ongoing MAAESTRO study, in which stroke patients with atrial fibrillation electronically monitor their adherence to DOAC treatment. Eligible patients for this analysis had at least four weeks of adherence data prior to and during the COVID-19 lockdown. Three adherence metrics (taking adherence, timing adherence, drug holidays) were calculated and compared descriptively. RESULTS The analysis included eight patients (median age 81.5 years, IQR 74.8-84.5). Five patients had a pre-lockdown taking adherence over 90% (mean 96.8% ± 2.9), with no change during lockdown, high timing adherence in both periods and no drug holidays. The remaining three patients had pre-lockdown taking and timing adherence below 90%. Of those, two patients showed a moderate decline either in taking or timing adherence compared to pre-lockdown. One showed a substantial increase in taking and timing adherence during lockdown (both + 25.8%). CONCLUSION Our data suggest that a major disruption of social life (i.e., the imposed COVID-19 lockdown) is unlikely to relevantly affect the medication intake behaviour of patients with high pre-established adherence, but might have an impact in patients with previously suboptimal adherence.

Abstract
Aims: To describe and compare the adherence to different direct oral anticoagulants (DOACs) in eight European databases representing six countries. Methods: Longitudinal drug utilization study of new users (≥18 years) of DOACs (dabigatran, rivaroxaban, apixaban) with a diagnosis of non-valvular atrial fibrillation (2008-2015). Adherence was examined by estimating persistence, switching, and discontinuation rates at 12 months. Primary non-adherence was estimated in BIFAP and SIDIAP databases. Results: The highest persistence rate was seen for apixaban in the CPRD database (81%) and the lowest for dabigatran in the Mondriaan database (22%). The switching rate for all DOACs ranged from 2.4 to 13.1% (Mondriaan and EGB databases, respectively). Dabigatran had the highest switching rate from 5.0 to 20.0% (Mondriaan and EGB databases, respectively). The discontinuation rate for all DOACs ranged from 16.0 to 63.9% (CPRD and Bavarian CD databases, respectively). Dabigatran had the highest rate of discontinuers, except in the Bavarian CD and AOK NORDWEST databases, ranging from 23.2 to 64.6% (CPRD and Mondriaan databases, respectively). Combined primary non-adherence for examined DOACs was 11.1% in BIFAP and 14.0% in SIDIAP. There were differences in population coverage and in the type of drug data source among the databases. Conclusion: Despite the differences in the characteristics of the databases and in demographic and baseline characteristics of the included population that could explain some of the observed discrepancies, we can observe a similar pattern throughout the databases. Apixaban was the DOAC with the highest persistence. Dabigatran had the highest proportion of discontinuers and switchers at 12 months in most databases (EMA/2015/27/PH).

Res Social Adm Pharm 2021; 18:3019-3026. [PMID: 34393080 DOI: 10.1016/j.sapharm.2021.07.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 07/30/2021] [Accepted: 07/30/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Patients with polypharmacy are challenged with the management of their daily medication. Medication management strategies for direct oral anticoagulants (DOAC) are especially important to guarantee medication adherence and to prevent thromboembolic events. Patients are often left alone with finding an appropriate strategy. OBJECTIVE(S) To explore medication management strategies, to measure adherence to DOAC with the aim of deducing recommendations for practice. METHODS Face-to-face semi-structured interviews were conducted at the home of outpatients who were taking ≥4 medications daily including a DOAC, and self-managing their medication. A small electronic device (Time4Med™) was given to record medication intake during the four following weeks. During a second home visit, participants saw a graph of their medication intake as dot chart, and obtained a feedback. Interviews were transcribed verbatim and thematically analysed. Medication adherence was calculated with electronic data. RESULTS Eighteen individuals (61.1% female; median age 77.5 years) were interviewed and reported 30 different medication management strategies, together with triggers, advantages and limitations. They combined at least five strategies, composed of internal (memory-based) and external (packaging-based or intake-based) strategies. The number of strategies was neither associated with the number of medications nor with medication adherence. Taking adherence was <100% for eight patients (44.4%). The inability of any medication management strategy to adapt to ageing and cognitive decline emerged as its most dramatic limitation, especially because individuals would fail to notice when their strategy became unsuited. CONCLUSIONS Elderly patients develop manifold medication management strategies, which can inspire future medication users. Limitations are present such as forgetting medication intake in spite of a management strategy. The moment to adapt the strategy to ageing or cognitive decline is crucial and often goes unnoticed. It is therefore decisive that healthcare professionals regularly re-evaluate the appropriateness of the medication management strategies during counselling or ideally during home visits.

Abstract
BACKGROUND Venous thromboembolism (VTE) affects nearly 1 million Americans annually, and many benefit from continued anticoagulation after the initial 3- to 6-month treatment period (secondary prevention). OBJECTIVES To determine whether warfarin, apixaban, or rivaroxaban is associated with reduced recurrent VTE hospitalization in the secondary prevention of VTE. PATIENTS/METHODS We performed a retrospective cohort study of participants enrolled in the MarketScan Insurance Database between 2013 and 2017 in those with an incident VTE. In those individuals who continued oral anticoagulation (warfarin, apixaban, or rivaroxaban) beyond 6 months, we determined the relative rate of recurrent VTE hospitalization. RESULTS Among 119 964 individuals with VTE, 25 419 remained on anticoagulation after 6 months and were matched successfully by age, sex, and date. After adjusting for a propensity score, apixaban versus rivaroxaban (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.45-0.94) and apixaban versus warfarin (HR, 0.68; 95% CI, 0.47-1.00) had a reduced risk of recurrent VTE hospitalization, and rivaroxaban versus warfarin (HR, 1.12; 95% CI, 0.94-1.33) had equivalent rates. For the rivaroxaban versus warfarin comparison there was a significant interaction by renal function (P < .01) where rivaroxaban was associated with a lower risk of recurrent VTE hospitalization (HR, 0.65; 95% CI, 0.41-1.03) in those with kidney disease and increased risk in those without kidney disease (HR, 1.24; 95% CI, 1.02-1.50). CONCLUSIONS These data suggest that apixaban has a lower recurrent VTE hospitalization rate than rivaroxaban during the secondary prevention of VTE, and further study of diverse patient populations, especially by kidney function, is warranted.

[PMID: 32622691 DOI: 10.1016/j.pec.2020.06.016] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 06/15/2020] [Accepted: 06/16/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVE To assess direct oral anticoagulant (DOAC) adherence and to determine possible determinants for suboptimal adherence in Dutch patients with atrial fibrillation (AF). METHODS Cross-sectional study of DOAC users who completed a self-reported questionnaire. Adherence was measured with Morisky8-item Medication Adherence Scale (MMAS-8). Logistic regression analysis was conducted to investigate determinants affecting adherence. RESULTS 398 DOAC users completed the questionnaire (mean age 70.6 ± 9.2years). Approximately one in four patients had suboptimal adherence (MMAS-8 < 8). Multivariable analysis showed that patients who felt to have received conflicting information about the treatment, patients with higher educational level and patients who were not sufficiently involved in the treatment choice had a higher odds of suboptimal adherence. CONCLUSION DOAC adherence was suboptimal. Conflicting information received from different healthcare providers (HCPs), lack of shared decision making and the patients' educational level were determinants negatively affecting DOAC adherence. PRACTICE IMPLICATIONS Efforts towards identifying suboptimally adherent DOAC patients are needed since they are at higher risk to develop thromboembolic events. Adherence counselling should be systematically and repeatedly encouraged and shared decision making should become more mainstream. Moreover, reinforced education of both patients and HCPs combined with interprofessional collaboration are potential solutions to prevent knowledge gaps and communication of conflicting information.

Insights Into Direct Oral Anticoagulant Therapy Implementation of Stroke Survivors with Atrial Fibrillation in an Ambulatory Setting. J Stroke Cerebrovasc Dis 2020; 30:105530. [PMID: 33333334 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105530] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 11/25/2020] [Accepted: 12/01/2020] [Indexed: 12/19/2022] Open
Abstract
OBJECTIVES To describe how stroke survivors with atrial fibrillation implement direct oral anticoagulant treatment and propose appropriate metrics to describe adherence. MATERIALS AND METHODS Stroke patients with atrial fibrillation electronically recorded their self-administered direct oral anticoagulants (apixaban, dabigatran, edoxaban, rivaroxaban) during a 6-month observation phase after hospitalisation for ischemic stroke. Taking and timing adherence, correct dosing days, drug holidays, time of the day and day of the week subsets, dose-to-dose intervals and longest intervals between two consecutive doses were calculated from electronic monitoring data to describe and discuss the implementation phase of adherence. RESULTS Data from 41 patients were analysed. Median age was 77 (IQR = 69-84), 63.4% were male and the majority suffered a mild stroke (median NIHSS: 1). Mean taking and timing adherence exceeded 90%. Correct dosing occurred in 86.6% of the days. Seven patients (17.1%) had intake pauses of three or more consecutive days. Patients with twice-daily regimen (70.7%) had higher taking adherence in the morning than in the evening (94.4% versus 89.9%; p = 0.001). No therapy- or anamneses-related characteristic was associated with taking adherence. CONCLUSIONS Although adherence to direct oral anticoagulants of stroke patients with atrial fibrillation exceeded 90%, deviant intake patterns such as drug holidays and missed evening doses were common and raise concerns. Appropriate adherence metrics calculated from electronic monitoring data may guide healthcare professionals elucidating patient-tailored adherence-enhancing interventions. ClinicalTrials.gov registration number: NCT03344146.

Abstract
BACKGROUND Anticoagulant therapy is used for stroke prevention and proved to be effective and safe in the long term. The study aims to analyse the cost-effectiveness relationship of using of direct-acting oral anticoagulants vs vitamin K antagonists to prevent ischaemic stroke in patients with nonvalvular atrial fibrillation, including all the active ingredients marketed in Spain, prescribed for 2 years in the Primary Care service of the Institut Català de la Salut. METHODS Population-based cohort study, in which the cost of the 2 treatment groups will be evaluated. Direct costs (pharmacy, primary care, emergency and hospitalization) and indirect costs (lost productivity) will be included from a social perspective. Effectiveness (assessed as the occurrence of a health event, the 1 of primary interest being stroke) will be determined, with a 2-year time horizon and a 3% discount rate. The average cost of the 2 groups of drugs will be compared using a regression model to determine the factors with the greatest influence on determining costs. We will carry out a univariate ('one-way') deterministic sensitivity analysis. DISCUSSION We hope to provide relevant information about direct and indirect costs of oral anticoagulants, which, together with aspects of effectiveness and safety, could help shape the consensual decision-making of evaluating bodies.

Abstract
Little is known about the impact of oral anticoagulation (OAC) choice on healthcare encounters during venous thromboembolism (VTE) primary treatment. Among anticoagulant-naïve patients with VTE, we tested the hypotheses that healthcare utilization would be lower among users of direct OACs (DOACs; rivaroxaban or apixaban) than among users of warfarin. MarketScan databases for years 2016 and 2017 were used; healthcare utilization was identified in the first 6 months after initial VTE diagnoses. The 23,864 patients with VTE had on average 0.2 ± 0.5 hospitalizations, spent 1.3 ± 5.2 days in the hospital, had 5.7 ± 5.1 outpatient encounters, and visited an emergency department 0.4 ± 1.1 times. As compared to warfarin, rivaroxaban and apixaban were associated with fewer hospitalizations, days hospitalized, outpatient office visits, and emergency department visits after accounting for age, sex, comorbidities, and medications. Hospitalization rates were 24% lower (incidence rate ratio (IRR): 0.76; 95% CI: 0.69, 0.83) with rivaroxaban and 22% lower (IRR: 0.78; 95% CI: 0.71, 0.87) with apixaban, as compared to warfarin (IRR: 1.00 (reference)). Healthcare utilization was similar between apixaban and rivaroxaban users. Patients with VTE prescribed rivaroxaban and apixaban had lower healthcare utilization than those prescribed warfarin, while there was no difference when comparing apixaban to rivaroxaban. These findings complement existing literature supporting the use of DOACs over warfarin.
