Satisfaction with oral anticoagulants in patients with atrial fibrillation

The impact of training on satisfaction and anxiety levels in stroke patients receiving warfarin treatment

PURPOSE

Due to the narrow therapeutic range of warfarin, patients require close monitoring. This study aimed to examine the effects of training provided to stroke patients receiving warfarin treatment on their perception of satisfaction and state of anxiety.

METHODS

This quasi-experimental study used a pretest-posttest design with similar groups and a control group.

RESULTS

Comparison of the posttest scores on the Duke Anticoagulation Satisfaction Scale revealed that the experimental group had significantly lower mean scores on the positive subscale and the total scale compared to the control group. When the Time in Therapeutic Range (TTR) status was evaluated, it was observed that 69.9 % of the patients in the intervention group and 21.7 % of the patients in the control group achieved a TTR ratio of 60 % or above.

CONCLUSIONS

Training provided to stroke patients receiving warfarin therapy improved their TTR ratio and increased their satisfaction levels but did not affect their anxiety levels. Based on these findings, it is recommended to prepare standardized training materials to enhance patient outcomes.

The efficacy and safety of direct oral anticoagulants compared with vitamin K antagonist in patients with hypertrophic cardiomyopathy and atrial fibrillation

BACKGROUND

The benefit-risk profile of direct oral anticoagulants (DOAC) therapy in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF) has not been well established yet. This study aimed to evaluate the efficacy and safety of DOAC compared with vitamin K antagonists (VKA) in patients with HCM and AF.

METHODS

PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov were searched to identify studies comparing DOAC with VKA in patients with HCM and AF. The primary endpoint was thromboembolic events. The relative risks and standard errors were pooled by random-effect models using the generic inverse variance method.

RESULTS

Seven observational studies involving 9395 patients were included in this meta-analysis. Compared to the VKA group, the DOAC group displayed a similar risk of thromboembolic events [RR (95%CI): 0.93 (0.73-1.20), p = 0.59] and ischemic stroke [RR (95%CI): 0.65 (0.33-1.28), p = 0.22]. The incidence of major bleeding was comparable between the two groups [RR (95%CI): 0.75 (0.49-1.15), p = 0.19]. Meanwhile, DOAC therapy was superior to VKA therapy in reducing the incidences of all-cause death [RR (95%CI): 0.44 (0.35-0.55), p < 0.001], cardiovascular death [RR (95%CI): 0.41 (0.22-0.75), p = 0.004], and intracranial hemorrhage [RR (95%CI): 0.42 (0.24-0.74), p = 0.003].

CONCLUSION

In patients with HCM and AF, DOAC therapy was similar to VKA therapy in reducing the risk of thromboembolic events, without increasing bleeding risk. In addition, the DOAC group displayed significant advantages in reducing mortality and intracranial hemorrhage compared with the VKA group. Further randomized controlled trials are needed to provide more evidence for DOAC therapy in this population.

Knowledge, Adherence, and Satisfaction With Warfarin Therapy and Associated Factors Among Outpatients at University Teaching Hospital in Ethiopia

Anticoagulation management using warfarin is challenging in clinical practice. This study aimed to evaluate the knowledge, adherence, and satisfaction with warfarin therapy and associated factors among outpatients at the Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa, Ethiopia. An interview-based cross-sectional study was conducted among 350 patients receiving warfarin therapy at cardiac and hematology clinics of TASH. Anticoagulation knowledge assessment (AKA) questionnaires assessed the patients' warfarin knowledge. Adherence to warfarin was evaluated using the Morisky Green Levine Scale (MGLS), and patient satisfaction with warfarin therapy was assessed using the 17-item anticlot treatment scale (ACTS). Binary logistic regression was used to determine factors associated with the outcome variables, and p < .05 was used as the cut-off point to declare a significant association. The mean AKA score was 59.35  ±  13.04% (10.68  ±  2.34 correct answers), and 82 (23.4%) of participants achieved a passing score. Based on the MGLS, 192 (54.9%) study participants adhered well to warfarin. The mean level of satisfaction was 53.67  ±  8.56, with mean scores of 41.93  ±  7.80 and 11.74  ±  2.43 in the ACTS burden and benefit subscales, respectively. One hundred eighty-four (52.6%) patients were satisfied with warfarin therapy. The absence of hyperthyroidism was significantly associated with poor knowledge of warfarin therapy (adjusted odds ratio [AOR] = 4.28, 95% confidence interval [CI]: 1.01-18.22). Those living with family had a 56% lower chance of poor warfarin adherence (AOR: 0.44; 95% CI: 0.21-0.93) than those living alone. This study shows room for improvement in patient knowledge, adherence, and satisfaction with warfarin therapy.

Comparison of the Efficacy and Safety of Direct Oral Anticoagulants and Warfarin in Cirrhotic Patients: A Systematic Review and Meta-Analysis

OBJECTIVE

Currently, there is limited evidence regarding the use of direct oral anticoagulants (DOACs) for patients with liver cirrhosis (LC). We performed a meta-analysis to compare the efficacy and safety of DOACs versus warfarin in this population.

METHODS

We searched PubMed, Cochrane Library, Web of Science, Embase and Scopus databases from inception to August 2024. Clinical studies comparing the use of DOACs with warfarin in cirrhotic patients were included. Hazard ratios (HRs) with 95% CIs were estimated by either fixed or random effects models. Primary efficacy outcomes were ischemic stroke/thromboembolism (IS/TE) and all-cause death, the primary safety outcomes were the bleeding risks.

RESULTS

Sixteen studies were included (16 829 individuals). DOACs had similar benefits in preventing IS/TE (HR = 0.87, 95% CI: 0.69-1.10), but DOACs were significantly associated with reduced risk of all-cause death (HR = 0.87, 95% CI: 0.79-0.97). On the other hand, we observed significantly reduced risks of any bleeding (HR = 0.60; 95%CI: 0.37-0.95), major bleeding (HR = 0.72; 95%CI: 0.63-0.82), intracranial hemorrhage (ICH) (HR = 0.47; 95%CI: 0.30-0.73), and gastrointestinal bleeding (GIB) (HR = 0.72, 95% CI: 0.60-0.87) in patients receiving DOACs. Results were consistent in cirrhotic patients with AF. Furthermore, DOACs reduced the incidence of major bleeding (HR = 0.65, 95%CI: 0.55-0.78) and ICH (HR = 0.17, 95%CI: 0.04-0.76) in patients with moderate to severe cirrhosis.

CONCLUSION

Our study demonstrates that DOACs, compared with warfarin, exerted comparable efficacy and better safety and may represent a safer alternative to warfarin in cirrhotic patients.

The relationship between self-efficacy and treatment satisfaction among patients with anticoagulant therapy: a cross-sectional study from a developing country

BACKGROUND

Thromboembolic events are a common complicated health problem. Although anticoagulants have several positive effects on these conditions, they also have several characteristics that strongly affect compliance and satisfaction. The purpose of this investigation is to explore the association between treatment satisfaction and self-efficacy in a sample of patients using anticoagulation therapy and determine the influence of sociodemographic and clinical factors on both aspects.

METHODS

This was a cross-sectional exploratory study carried out in Palestine. The Arabic version of the Anti-Coagulant Treatment Satisfaction Scale (ACTS) assessed treatment satisfaction. In addition, the Arabic version of the 6-Item Self-Efficacy for Managing Chronic Diseases (SES6C) was used to assess self-efficacy.

RESULTS

A total of 300 patients using anticoagulants (average age 51.95 and SD 17.98) were included. There is a modest correlation between treatment satisfaction and self-efficacy (r = 0.345; p <  0.001). The mean and median self-efficacy scores were 38.41 ± 9.88 and 39.00 (interquartile range: 33.00-46.00), respectively. Overall, patients reported a moderate burden and benefit score. The mean and median of the acting burden were 43.30 ± 10.45, and 43.30 (interquartile range: 36.00 to 51.00), respectively. The results showed that young age, higher education, employment, use of fewer medications, and having fewer diseases were significantly associated with higher self-efficacy behaviors. The results also showed that new oral anti-coagulants (NOACs) had a higher degree of self-efficacy and ACTS benefit scores (41.00 (33.75-47.00), p = 0.002; 13.00 (12.00-15.00), p <  0.001, respectively), than vitamin k antagonists (VKA).

CONCLUSIONS

The results demonstrated a significant relationship between treatment satisfaction and self-efficacy, and certain sociodemographic and clinical characteristics influence both. We found that there is a higher degree of self-efficacy and treatment satisfaction among patients who use NOACs than those who use UFH / VKA. Therefore, patients should be motivated to increase their knowledge about anticoagulant therapy. Healthcare providers should play an active role in educating patients, increasing their self-esteem, and awareness about anticoagulant drugs. Importantly, this study was an explanatory one, and it includes a low proportion of patients with venous thromboembolism. This encourages future research on a large scale of patients, considering the indications of anticoagulant therapy.

Satisfaction With Oral Anticoagulants Among Patients With Atrial Fibrillation: A Prospective Observational Study

Background

Satisfaction with treatment has been identified as an important contributing factor to adherence with oral anticoagulant (OAC) therapy in patients with atrial fibrillation (AF). We aimed to evaluate the satisfaction level of patients with AF regarding OAC use over time, using validated patient-reported outcome instruments, and to identify associated patient characteristics.

Methods

Participants were recruited from specialized AF clinics in Canada. Eligible AF patients who were prescribed OACs were followed for up to 2 years. Participants were interviewed via telephone every 3-4 months using a structured survey. The Treatment Satisfaction Questionnaire for Medication (TSQM II) and the Anti-Clot Treatment Scale (ACTS) were used to measure satisfaction over time.

Results

Among the 306 participants, satisfaction scores on the TSQM II and ACTS instruments were high. Unadjusted analyses showed significantly greater satisfaction with the burden of therapy with direct OACs (DOACs) compared to that with warfarin (small-magnitude effect) and greater satisfaction with the convenience of rivaroxaban, compared with that of all other OACs (moderate-magnitude effect). After adjustment for all other variables, vitamin K antagonist therapy was associated with greater global satisfaction than was DOAC treatment. Satisfaction with benefit and burden as measured by the ACTS scale, and global satisfaction on the TSQM II scale, tended to increase over time. Patient factors that were somewhat consistently associated with greater satisfaction were female sex and younger age.

Conclusions

Patients with AF were highly satisfied with their therapy, with few differences among OAC classes and individual OACs. Individual patients may or may not be more satisfied with DOAC than VKA therapy, and regardless of the OAC prescribed, the may require significant support to maintain therapy adherence.

Patient perception and treatment convenience of dabigatran versus vitamin K antagonist when used for stroke prophylaxis in atrial fibrillation: Real-world Evaluation of Long-term Anticoagulant Treatment Experience (RE-LATE) study

Purpose

Dabigatran is a direct thrombin inhibitor approved for stroke prophylaxis in patients with non-valvular atrial fibrillation (NVAF). Real-world data about patient preference, satisfaction and convenience in patients in Asia are not available. The study aimed to explore the perception of patients with newly diagnosed NVAF regarding dabigatran versus vitamin K antagonists (VKAs), when used for stroke prevention.

Patients and methods

This was a multinational, multicentre, non-interventional study involving 49 sites across 5 countries in South East Asia and South Korea where 934 patients newly diagnosed with NVAF were initiated on either dabigatran (N=591) or VKA (N=343). Data were collected at baseline and over two follow-up visits across 6 months. Treatment satisfaction and patient convenience were evaluated using the Perception on Anticoagulant Treatment Questionnaire-2 (PACT-Q2).

Results

The mean age of the patients was 65.9±10.4 years, and 64.2% were male. Mean CHA₂DS₂-VASc score was 2.4±1.5, and mean HAS-BLED score was 1.2±0.9. At baseline, patients initiated on dabigatran had higher stroke risk, bleeding risk, creatinine clearance and proportion of patients with concomitant illnesses compared with patients initiated on VKAs. Treatment convenience was perceived to be significantly better with dabigatran versus VKAs at visits 2 and 3 (p=0.0423 and 0.0287, respectively). Treatment satisfaction was significantly better with dabigatran compared with VKAs at visit 3 (p=0.0300).

Conclusion

In this study, dabigatran is associated with better patient perception in terms of treatment convenience and satisfaction compared with VKAs when used for stroke prevention in newly diagnosed NVAF patients from South East Asia and South Korea.

Trial registration number

NCT02849509.

Plain language summary

Patient satisfaction with dabigatran versus VKAs in South East Asia. Patients with atrial fibrillation are at high risk of stroke and require anticoagulants for stroke prevention. Two such anticoagulants are dabigatran and VKAs. We wanted to compare the extent of satisfaction and treatment convenience among newly diagnosed patients with atrial fibrillation from the South East Asian region when they were given either dabigatran or VKAs. Consenting patients filled out a standardised questionnaire called the PACT-Q2 over three visits after they were started on either dabigatran (591 patients) or VKAs (343 patients). We found that satisfaction and convenience were significantly higher when patients received dabigatran than when they received VKAs.

Beyond Ablation in Atrial Fibrillation: 10 Steps to Better Control

The prevention and treatment of atrial fibrillation includes risk factor modification beyond ablation, with lifestyle modifications including treatment of obesity through diet and moderate exercise being at the top of the list. Losing 10% of body weight if obese, a plant-based diet, exercise, maintaining systolic blood pressure below 130 mm Hg, treatment of sleep disorders and obstructive sleep apnea, stress management, and treatment of depression and anxiety should all be included in treatment. Maximizing evidence-based treatment of chronic obstructive pulmonary disease and diabetes is also paramount.

Efficacy and safety of direct oral anticoagulants (DOACs) versus vitamin K antagonist (VKA) among patients with atrial fibrillation and hypertrophic cardiomyopathy: a systematic review and meta-analysis

Background/objectives: Long-term oral anticoagulant therapy is recommended for patients with hypertrophic cardiomyopathy (HCM) who develop atrial fibrillation (AF) to prevent cardioembolic complications. In patients with non-valvular AF, direct oral anticoagulants (DOACs) has been proved to be non-inferior to adjusted-dose vitamin K antagonist (VKA). However, the role of DOACs in patients with AF in the setting of HCM has not been fully established.Methods: A comprehensive literature review was conducted by searching for published articles indexed in MEDLINE and EMBASE databases from inception through 1 May 2019. Eligible studies must start with recruitment of patients with AF in the setting of HCM who received either DOACs or VKA. The studies must follow them for the occurrence of ischaemic stroke. Hazard ratio (HR) and confidence interval (CI) of developing ischaemic stroke between the two groups must be reported. Pooled HR was calculated using a random-effect, generic inverse variance method of DerSimonian and Laird.Results: A total of three retrospective cohort studies with 4,418 participants met the eligibility criteria and were included into the meta-analysis. A significantly lower risk of all-cause death was observed in the DOACs group than in the VKA group with the pooled HR of 0.43 (95% CI, 0.33-0.58, I² = 0%). However, the risk of ischaemic stroke among patients with AF and HCM who received DOACs was not significantly different from those who received VKA with the pooled HR of 0.95 (95% CI, 0.73-1.22, I² = 0%). Both major bleeding and intracranial bleeding were also not significantly different between those who received DOACs versus those who received VKA with the pooled HR of 0.94 (95% CI, 0.70-1.26, I² = 0%) and 0.61 (95% CI, 0.27-1.37, I² = 0%), respectively.Conclusions: The current study found that the risk of all-cause death was significantly reduced but the risk of ischaemic stroke, major bleeding and intracranial bleeding were not significantly different between patients with AF and HCM who had received DOACs and those who received VKA.

Satisfaction of Patients with Nonvitamin K Anticoagulants Compared to Vitamin K Antagonists: a Systematic Review and Meta-analysis

OBJECTIVE

 To undertake a systematic review and meta-analysis to assess the satisfaction of patients receiving nonvitamin K anticoagulants (NOACs), compared with vitamin K antagonists (VKAs).

METHODS

 We searched CENTRAL, MEDLINE, Embase, and Clinicaltrials.gov for randomized controlled trials (RCTs) and observational studies. Two reviewers screened, extracted, and appraised data independently. We pooled data using a random-effects model. Outcome included treatment satisfaction, which was assessed by scores of Duke Anticoagulation Satisfaction Scale (DASS), Anticlot Treatment Scale (ACTS), Perception of Anticoagulant Treatment Questionnaire 2 (PACT-Q2), or Treatment Satisfaction Questionnaire for Medication version II (TSQM-VII) and their domains reported with 95% confidence intervals (95% CIs). We followed MOOSE and PRISMA guidelines.

RESULTS

 We included four RCTs and 16 observational studies, enrolling 18,684 participants overall. Compared with VKAs, treatment with NOACs improved the ACTS Burdens score by 4.21 points (95% CI: 2.99-5.43, I ² = 95%, combined n = 6,180), and ACTS Benefits by 0.49 points (95% CI: 0.18-0.81, I ² = 85%, combined n = 6,171). Switching from VKAs to NOACs improved the ACTS Burdens score by 5.33 points (95% CI: 3.53-7.14, combined n = 3,097). Compared with VKAs, treatment with NOACs improved the TSQM-VII Global Satisfaction score by 6.86 points (95% CI: 3.00-10.73, combined n = 5,535).

CONCLUSION

 In patients with nonvalvular atrial fibrillation or venous thromboembolism, NOAC treatment is associated with greater satisfaction compared with VKAs. The switch from VKAs to NOACs was associated with improved patients' satisfaction. These effects were largely due to a lower degree of treatment burden with NOAC treatment.

Time in therapeutic range, quality of life and treatment satisfaction of patients on long-term warfarin for non-valvular atrial fibrillation: a cross-sectional study

BACKGROUND

The use of warfarin in patients with non-valvular atrial fibrillation (NVAF) can be challenging. In this study, we evaluate the time in therapeutic range (TTR), health-related quality of life (HRQoL) and treatment satisfaction of patients on long-term warfarin for NVAF. The HRQoL and treatment satisfaction were compared based on the TTR.

METHODS

A cross-sectional study was conducted among patients on warfarin for NVAF who attended the anticoagulant clinic of a tertiary cardiology referral center in Sarawak from 1st June 2018 to 31st May 2019. Patients' TTR was calculated by using Rosendaal technique, while their HRQoL and treatment satisfaction were assessed by using Short Form 12 Health Survey version 2 (SF12v2) and Duke Anticoagulant Satisfaction Scale (DASS), respectively.

RESULTS

A total of 300 patients were included, with mean TTR score of 47.0 ± 17.3%. The physical component summary (PCS) and mental component summary (MCS) score of SF-12v2 were 47.0 ± 9.0 and 53.5 ± 9.6, respectively. The total score for DASS was 55.2 ± 21.3, while the score for limitations (L), hassles and burdens (H&B) and positive psychological impacts (PPI) were 18.0 ± 10.0, 15.6 ± 9.1 and 21.6 ± 5.9, respectively. Seventy-three (24.3%) patients had good TTR (≥ 60%), with mean of 70.2 ± 8.7%; while 227 (75.5%) patients with poor TTR had significantly lower mean of 39.5 ± 11.9% (p = 0.006). There was no significant difference in the score of PCS (p = 0.150), MCS (p = 0.919) and each domain of SF-12v2 (p = 0.184-0.684) between good and poor TTR, except for social functioning (p = 0.019). The total DASS score was also not significantly different between group (p = 0.779). Similar non-significant difference was also reported in all the DASS sub dimensions (p = 0.502-0.699).

CONCLUSIONS

Majority of the patients on long-term warfarin for NVAF in the current study have poor TTR. Their HRQoL and treatment satisfaction are independent of their TTR. Achieving a good TTR do not compromise the HRQoL and treatment satisfaction. Therefore, appropriate measures should be taken to optimise INR control, failing which direct oral anticoagulant therapy should be considered.

Patients' perceptions with dabigatran in patients with atrial fibrillation previously treated with vitamin K antagonists

Aim: To analyze the perception of anticoagulation with dabigatran in patients with nonvalvular atrial fibrillation previously treated with vitamin K antagonists over a 6-month period. Materials & methods: This is a prospective, noninterventional, noncontrolled, multicenter study. To assess patients' perceptions, PACT-Q2 questionnaire was completed. Results: Six hundred and fifty nine patients (73.1 ± 9.4 years, CHA₂DS₂-VASc 3.6 ± 1.6) were included. At baseline, the convenience and satisfaction scores were 60.9 ± 24.9 and 49.9 ± 17.7, respectively. The scores significantly increased along the study. Convenience score was higher in males and in patients with low-moderate thromboembolic risk. Satisfaction score was higher in females. Only 8.0% of patients discontinued dabigatran (3.7% due to side effects). Conclusion: Convenience and satisfaction scores for nonvalvular atrial fibrillation patients treated with dabigatran at 6 months were significantly better than with previous vitamin K antagonists.

Quality of life after switching from well-controlled vitamin K antagonist to direct oral anticoagulant: Little to GAInN

BACKGROUND

Direct oral anticoagulants (DOAC) and vitamin K antagonists (VKA) prevent thromboembolism in atrial fibrillation (AF). DOAC have a fixed dosing regimen and obviate INR monitoring. Therefore, DOAC presumably affect quality of life (QoL) less than VKA. However, some VKA users appreciate the monitoring. A high time in the therapeutic range (TTR) leads to a lower impact on QoL. We assessed the influence of switching from well-controlled VKA to a DOAC on QoL.

METHODS

In the GAInN study, 241 patients with AF, a TTR ≥ 70%, and neither bleeding nor thrombosis while on VKA were randomised to switching to DOAC (n = 121) or continuing VKA (n = 120). Health-related (SF-36) and anticoagulation-related QoL (PACT-Q) was assessed at baseline and after six and twelve months of follow-up.

RESULTS AND CONCLUSION

SF-36 development did not differ between groups. After one year, average PACT-Q Convenience improvement was 2.5 (0.3-4.7) higher on DOAC. DOAC users were 6percentage points (95%CI -4-16) more likely to improve >5 points on Convenience; 22 pp. (95%CI 1-43) in patients who scored <95/100 at baseline. The probability to meaningfully improve on PACT-Q Satisfaction was 12 pp. (95%CI 0-25) higher on DOAC. However, 5 (4.1%) and 4 (3.3%) DOAC users resumed VKA because of side-effects and patient preference. Switching from well-controlled VKA to DOAC for AF leads to a higher probability of improved PACT-Q convenience and satisfaction, but also to a higher risk of side-effects. Arguably only patients who are not satisfied with VKA should switch, because they have more to gain by switching.

Anticoagulation Therapy by Age and Embolic Risk for Nonvalvular Atrial Fibrillation in Mexico, an Upper-Middle-Income Country: The CARMEN-AF Registry

Background

Documenting the patterns of oral anticoagulation therapy (OAT) is essential to prevent thromboembolic complications of nonvalvular atrial fibrillation (NVAF).

Objective

To report the patterns of OAT according to age and thromboembolic risk in patients included in CARMEN-AF, a nationwide registry of NVAF in Mexico, an upper middle-income country.

Material and methods

There were 1,423 consecutive patients ≥18 years old and with at least one thromboembolic risk factor enrolled in the CARMEN-AF Registry at their regular clinical visit during a three-year period. They were analyzed according to 1) age, 2) AF type, and 3) CHA2DS2-VASc score.

Results

Overall, 16.4% of patients did not receive antithrombotic treatment, 19.4% received antiplatelet drugs (APD), 29.2% vitamin K antagonists (VKA), and 34.6% direct oral anticoagulants (DOAC). With increasing age, the proportion of subjects treated with VKA decreased significantly from 36.2% in subjects <65 years to 22.5% in those ≥75 years old (P <0.0001). Concomitantly, an increase in both APD and no antithrombotic treatment was observed with increasing age. DOAC were prescribed equally among all age groups (34.2% in <65, 36.0% in 65-74, and 33.9% in ≥75). According to the type of AF, VKA use was more common in patients with permanent AF (32.7%). A lower use of DOAC was observed in high thromboembolic risk subjects (33.6% in CHA2DS2-VASc ≥2) compared with the moderate risk group (41% in CHA2DS2-VASc = 1).

Conclusions

VKA use for NVAF in Mexico decreased in relation to increasing age. The proportion of DOAC therapy was the same in all age groups. Nevertheless, elderly patients with high thromboembolic risk received a suboptimal thromboprophylaxis. These data could help to improve gaps in the implementation of global guidelines.

Clinical trial registration

http://www.clinicaltrials.gov. Unique identifier: NCT02334852.

Highlights

CARMEN-AF is a nationwide multi-centric registry seeking to bridge the data gap on anticoagulation therapy for NVAF in Mexico.Elderly patients are more prone to receive suboptimal OAT for NVAF.DOAC were less frequently used in high thromboembolic risk patients (CHA2DS2-VASc ≥2).

Clinical profile and management of rivaroxaban in patients with atrial fibrillation in routine practice in Spain: data from six nationwide studies

AIMS

To analyze the clinical profile and management of patients with nonvalvular atrial fibrillation taking rivaroxaban in routine practice in Spain.

METHODS

Clinical data from the observational studies HEROIC (cardiology and hematology; n=1,727), EMIR (cardiology; n=1,493), BRONCE-AP (primary care; n=133), SILVER-AP (primary care; n=457), ALADIN (internal medicine and neurology; n=249), and ESPARTA (internal medicine; n=110) of patients taking rivaroxaban were analyzed. The clinical profile was compared with those of the XANTUS and ROCKET-AF studies.

RESULTS

Overall, mean age was 74.9±9.4 years, CHA₂DS₂-VASc score was 3.7±1.5, and 43.2% had a HAS-BLED score ≥3. Patients included in the HEROIC and EMIR studies were older and more frequently had a creatinine clearance <50 mL/min and a higher thromboembolic risk than those in the XANTUS study, and patients included in the ALADIN study were older and had more prior cerebrovascular disease, but a lower thromboembolic risk than those in the ROCKET-AF trial. In those studies with available data, medication adherence and satisfaction with rivaroxaban were high.

CONCLUSION

Bearing in mind differences according to the clinical setting of each study, atrial fibrillation patients taking rivaroxaban in Spain were elderly and had a high thromboembolic risk. Medication adherence and satisfaction with rivaroxaban were high.

A systematic review of patient-reported outcomes associated with the use of direct-acting oral anticoagulants

AIMS

Patient-reported outcomes (PROs) are a distinctive method of evaluating patient response to health care or treatment. This systematic review aimed to analyse the impact of PROs in patients on direct oral anticoagulant (DOAC) treatment, prescribed for any indication (e.g. venous thromboembolism treatment or atrial fibrillation) using controlled trials (CT) and real-world observational studies (OS).

METHODS

A systematic search of articles was conducted according to PRISMA guidelines using databases, with the last update in November 2018. The Cochrane Collaboration tool for assessing bias in randomized CTs and the Newcastle-Ottawa Scale adapted for cross-sectional studies were used. Outcomes evaluated were related to health-related quality of life (HRQoL), satisfaction, adherence and compliance.

RESULTS

Twenty-one original studies (6 CT, 15 OS) were included. HRQoL was assessed by 6 (1 CT, 5 OS) studies and reported that HRQoL scores were similar in patients on DOACs and warfarin. Patients prescribed DOACs presented higher HRQoL scores which were attributed to lack of intense monitoring required compared with warfarin but this was not statistically significant. The majority of studies (5 CT, 9 OS) investigated patient-reported satisfaction, indicating greater satisfaction with DOACs with significantly lower burden and increased benefit scores for patients on DOACs. Patient-reported expectations, compliance and adherence were similar for patients on DOACs and warfarin.

CONCLUSION

Patients appear to prefer treatment with DOACs vs warfarin. This is shown by the higher quality of life, satisfaction and adherence described in the studies. However, heterogeneity in the analysed studies does not allow firm conclusions.
