“…This hypothesis was also confirmed by other investigations, demonstrating that the greater the patient’s knowledge about treatment with warfarin, the better was the control of oral anticoagulation, as expressed by higher TTR values [ 11 , 20 ]. We observed that formal education and income showed a weak association with the OAK Test, which is similar to the results of other studies that have not demonstrated significant associations between knowledge and these variables as well [ 8 , 21 ].…”

Background: The aim of this study was to evaluate the psychometric properties of the Brazilian version of the Oral Anticoagulation Knowledge (OAK) Test. Methods: This study, conducted in an anticoagulation clinic, included 201 Brazilian participants aged over 18 years, who had been using warfarin for more than two months. The reliability of the instrument was evaluated by assessing internal consistency (Kuder-Richardson coefficient) and reproducibility (test-retest reliability). The validity was evaluated by hypothesizing that there would be a positive correlation of moderate to strong intensity between the correctness levels of the OAK Test and time within therapeutic range (TTR) values, which is a measure used to evaluate the quality of oral anticoagulation. Results: The instrument exhibited good psychometric properties. The total a Kuder-Richardson coefficient value was 0. 818 and intraclass correlation coefficient was 0.967. The validity revealed a strong positive correlation between the values of the level of knowledge, as measured by the OAK Test and the TTR values (r s = 0.780). Conclusion:The instrument proved to be a reliable and valid tool for evaluating the knowledge of Brazilian patients on oral anticoagulation therapy with warfarin. This instrument may be incorporated into the practice of health care for substantiating the structuring of educational activities to ensure the improvement of knowledge about the use of warfarin, thereby increasing the effectiveness and safety of treatment.

“…Regarding knowledge, although our patients initially received basic information about warfarin in a face-to-face interview supplemented with written material when the medication was prescribed to them and on their registration at the ACC, the baseline level of warfarin knowledge assessed among the patients in this study using the robust validated test, the AKA, showed a significant knowledge gap before the intervention. This result may not be surprising given the consistent findings of unsatisfactory anticoagulant knowledge reported in previous national survey studies[ 24 34 ] based on different knowledge examination tests (such as the Oral Anticoagulation Knowledge [OAK] test). [ 27 ] This finding highlighted the fact that patients may need continuing education, which supports the purpose for conducting this study; other research studies have also suggested that continuing education for long-term warfarin users, together with its sustained beneficial communication between health-care providers and their patients, are mandatory for successful anticoagulant management.…”

“…[ 26 27 ] Additionally, according to the protocols of the ACCs in main medical centers in Riyadh, the capital of KSA, alternative services (such as INR testing, warfarin dose adjustment, and side effects monitoring) are offered to a large population. [ 24 34 , 36 ] Providing additional education via an audiovisual intervention to patients who are receiving warfarin could summarize the educational message, improve efficiency in the clinic, and help busy clinics provide other necessary routine services to a larger number of regular visitors to the ACC without compromising staff time and efforts, unlike time- and effort-intensive traditional teaching methods.

A BSTRACT Context: Internationally, various warfarin education strategies have been described in the medical literature and delivered by a variety of health-care providers. However, none of these were tested in a Saudi setting. Aim: The aim of this study was to assess the impact of pharmacist interventions via an educational video on improving patient knowledge of and satisfaction with warfarin therapy and the international normalized ratio (INR). Setting and Design: This study adopted a prospective pre- and posttest design and enrolled 91 patients from an anticoagulant clinic at King Khaled University Hospital in Riyadh, Saudi Arabia, between September 2017 and February 2018. Materials and Methods: All patients completed the Anticoagulation Knowledge Assessment (AKA) and Anti-Clot Treatment Satisfaction (ACTS) scales. Subsequently, the patients watched a 10-min educational video containing basic information regarding warfarin and were given relevant informative booklets. The patients were reassessed after a mean follow-up period of approximately 52 days. Results: In total, 85 patients completed the study. The impact of the intervention on patient knowledge was highly significant (mean difference = 17.7%, 95% confidence interval (CI) = 21.75–13.58, P < 0.000). In addition, the patients showed significant increases in their ACTS benefits subscale scores (mean difference = 0.73, 95% CI = 1.22–0.24, P = 0.004). Despite being long-term warfarin users, the patients’ INRs had a greater tendency to be within the target range after the intervention (56.63% ± 35% vs. 64.72% ± 35% of the time; mean difference, 8.1 percentage points; effect size = 0.23). However, there was no significant effect on patients’ perceptions of the warfarin burden. Conclusion: This study provided evidence that a pharmacist-led audiovisual intervention via an educational video coupled with an informational booklet effectively improved patients’ knowledge retention and satisfaction with warfarin therapy benefits. Longer studies are needed to determine the impact of this intervention on patients’ perceptions of warfarin burdens and their INRs.

“…In Saudi Arabia, ACC services were introduced in the healthcare system, mainly in Riyadh, in the early 2000s. Currently, ACCs guided by clinical pharmacists have been established in almost every governmental health center [27][28][29][30][31] . Surprisingly, lack of knowledge on basic aspects of warfarin is very high (50-70 %) [27][28][29][30][31] .…”

Background: Previous studies have demonstrated inadequate patient knowledge about basic aspects of warfarin therapy, leading to nonadherence. Patients may not receive adequate education because of time constraints, lack of availability of resources, or other patient variables beyond the control of healthcare providers, such as poor patient recall. Objective: We explored the impact of a specifically developed mobile application (mApp)-Coagulation and Anticoagulant Therapy and Awareness (CATA)-on improving the knowledge and anticoagulation satisfaction of patients receiving warfarin therapy. Setting: Two medical centers' anticoagulant clinics (ACCs) in Riyadh, Saudi Arabia. Method: This was a prospective multi-center study with a single-arm pre-and post-test design; 45 patients (32 women; Mage = 45.82 ± 12.8 years) were enrolled. Main outcome measure: Patients' knowledge and anticoagulation satisfaction were evaluated at baseline and after a post pharmacist-led mHealth App educational intervention. Results: The CATA intervention had a significant impact on knowledge improvement; however, no significant changes were observed in satisfaction. Conclusions: The newly developed CATA mApp has vast potential in improving patients' knowledge; however, further exploration of factors behind the nonsignificant change in patients' anticoagulation satisfaction requires investigation in long-term prospective studies with more frequent pharmacists' interventions in ACCs.
