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

Pharmacy-Led Management of Atrial Fibrillation: Improving Treatment Adherence and Patient Outcomes

The world's population is ageing, with the number of those over 60 years expected to represent a fifth of the total population by 2050. Increases in chronic long-term health conditions (LTCs) associated with ageing, and requiring regular but often avoidable medical intervention, are pressurising already overloaded, health and social care systems. Atrial fibrillation (AF) is an LTC, which is most frequently diagnosed in the elderly. An often, asymptomatic condition, AF is associated with a 3- to 5-fold increased risk of severe ischemic stroke. Stroke prevention, with risk-stratified oral anticoagulants (OACs) is the standard recommended care for patients with AF. Stroke avoidance is, however, dependent on persistent adherence to OAC medication, with an adherence rate of >80% considered necessary to achieve optimal health outcomes. Suboptimal adherence to OACs is common, with a third of all AF patients not taking their medication as prescribed. This combined with the short half-life of OACs can result in poor clinical outcomes for patients. Policy makers now consider improving adherence to prescribed medicines for LTCs, a public health priority, to ensure better health outcomes for patients, whilst minimising unnecessary health system costs. Prescribing medicines to treat LTCs, such as AF, is not enough, particularly when the patient may not experience any measurable benefit to the treatment and may instead, experience medication-associated adverse events, including a risk of bleeding. Pharmacists who are experts in medicines management are ideally placed to support medication adherence, to educate, and to improve health outcomes for patients with AF. In this review, I will consider the evidence for poor medication adherence in LTCs and in particular adherence to OACs in patients with AF and highlight the role that pharmacists can play in ensuring optimal adherence and showcase pharmacist-led interventions that effectively address this problem.

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.

Evaluation of Satisfaction with Healthcare Services in Multimorbid Patients Using PACIC+ Questionnaire: A Cross-Sectional Study

Background and Objectives: Although multimorbidity poses many challenges for both individuals and healthcare systems, information on how these patients assess the quality of their healthcare is lacking. This study assessed the multimorbid patients' satisfaction with their healthcare. Materials and Methods: This cross-sectional study was a part of a project Joint Action-Chronic Diseases and Promoting Healthy Ageing across the Life Cycle and its implementation. The study included 400 patients with arterial hypertension and at least one concomitant chronic disease. Patients completed The Patient Assessment of Care for Chronic Conditions Plus (PACIC+) questionnaire, EuroQol Five-Dimensions-Three-Level Quality of Life questionnaire, and Hospital Anxiety and Depression scale. Results: The mean age of the participants was 65.38 years; there were 52.5% women. The mean PACIC+ 5As summary score was 3.60. With increasing age, participants rated worse on most PACIC+ subscales. Participants who assessed their quality of life as worse were also less satisfied with their healthcare. The presence of three or more concomitant diseases negatively affected PACIC+ scores. Patients with ischemic heart disease and heart failure had lower PACIC+ scores on most subscales, whereas patients with atrial fibrillation had lower scores only on the Agree subscale. The presence of diabetes was not associated with worse PACIC+ scores; moreover, the scores in Assist and Arrange subscales were even better in diabetic patients (3.36 vs. 2.80, p = 0.000 and 3.69 vs. 3.13, p = 0.008, respectively). Patients with chronic obstructive pulmonary disease, asthma, and musculoskeletal disorders showed lower PACIC+ scores. Conclusions: Older age, worse self-assessed health state, presence of three or more diseases, and certain chronic diseases were associated with lower patients' satisfaction with their healthcare. Personalized healthcare, increasing competencies of primary healthcare teams, healthcare services accessibility, and financial motivation of healthcare providers may increase multimorbid patients' satisfaction with their healthcare.

Oral anticoagulant adherence and switching in patients with atrial fibrillation: A prospective observational study

BACKGROUND

Adherence to oral anticoagulants (OACs) in patients with atrial fibrillation (AF) is important in preventing stroke. The dominance of retrospective studies using administrative data has led to a lack of data on psychosocial determinants of adherence and prevented comparison of adherence between OAC drug classes. OAC switching is another aspect of adherence that is unexplored.

METHODS

A prospective design was utilized to measure AF patients' self-reported adherence and OAC switching, and to identify their clinical, demographic, and psychosocial determinants. Participants were recruited from specialized AF clinics in Canada and followed for up to 2 years. Data were collected via telephone every 3-4 months using a structured survey. Adherence was measured using the Morisky Medication Adherence scale (©MMAS-8).

RESULTS

The included participants (N = 306) were followed for a median follow up time of 14.1 months and had an average of 3.2(SD 1.4) study visits. The mean self-reported adherence on the ©MMAS-8 was 7.28(SD 0.71) for patients receiving care at specialized AF clinics. Older age, experiencing a bleed, and higher satisfaction with the burden of medications were significantly associated with higher adherence. Drug class did not have any significant impact on adherence. 7.8% of the cohort experienced a switch with most of them being from warfarin to DOAC. Taking warfarin as the index medication, experiencing a bleed and older age were significantly associated with higher odds of switching.

CONCLUSION

Patients with AF reported high adherence to their OAC therapy however being on DOAC may not translate to better adherence compared to VKA. Improving satisfaction with the burden of therapy is important in improving adherence.

Patient satisfaction with quality of care of a multidisciplinary thrombosis service - a cross sectional survey

Background

In October 2017 we opened a multidisciplinary Adult Outpatient Thrombosis Service (Thrombosis Service) in a regional health authority servicing over 300 000 people. The Thrombosis Service is a comprehensive thrombosis and anticoagulation management program with unique, interrelated clinics providing a broad spectrum of care for this patient group. Evaluation of patient satisfaction with this new model of patient care is an important quality measurement.

Methods

We conducted a cross-sectional survey of patients who attended the Thrombosis Service between October 2017 and May 2019. We measured patient satisfaction with the seven-item Short Assessment of Patient Satisfaction (SAPS) which uses a 5 point scale (0–4) for responses. The continuous score range for SAPS is 0 to 28. Categorical responses for SAPS are defined as 0–10 very dissatisfied, 11–18 dissatisfied, 19–26 satisfied, and 27–28 very satisfied. We used linear regression analysis to examine the associations between patients’ characteristics and their satisfaction with the Thrombosis Service.

Results

Of the 1058 surveys distributed, 563 were returned. The mean score for the SAPS was 22.1 (SD 4.1, range 8 to 28). For the categorical response, 85% were satisfied or very satisfied with the Thrombosis Service. The multivariate analysis showed patients with post-secondary education were more satisfied with the Thrombosis Service (β-coefficient 1.6153, p = 0.024), and patients taking warfarin were less likely to be satisfied with the Thrombosis Service (β-coefficient -1.5832, p = 0.0390).

Conclusions

The majority of survey participants (85%) who attended an appointment in one of the Thrombosis Service clinics were satisfied or very satisfied with the care they received. This information may benefit other centres who are interested in developing a program to manage thrombosis and anticoagulation.
