Mameli A, Sestu A, Marongiu F, Barcellona D. Living on Oral Anticoagulants: Duke Anticoagulation Satisfaction Scale Results. J Clin Med 2023; 12:7574. [PMID: 38137642 PMCID: PMC10743469 DOI: 10.3390/jcm12247574] [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: 10/21/2023] [Revised: 12/03/2023] [Accepted: 12/06/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND Direct oral anticoagulants (DOACs) are widely used in patients with atrial fibrillation and venous thromboembolism. The lack of the need for laboratory monitoring and a better safety than vitamin K antagonists (VKAs) has probably changed the quality of life of patients on these oral anticoagulants. This was a real-life prospective observational cohort study. The aim was to evaluate if a long-term treatment with DOACs could offer a better quality of life than VKAs. Moreover, age, gender, education level, time in therapeutic range for VKAs, taking medication once or twice a day for DOACs, the total daily number of medications and thrombotic and bleeding complications were considered as variables probably associated with the quality of life of these patients. METHODS Between January and December 2021, the Duke Anticoagulation Satisfaction Scale (DASS) 25-items was administered as an interview to patients on either VKAs or DOACs therapy. During the follow-up period, all of the patients were closely monitored to evaluate possible bleeding and thrombotic events. RESULTS The analysis included 300 outpatients treated with VKAs and 254 treated with DOACs. In general, the quality of life was better in patients taking DOACs (DASS total score: DOACs = 44.7, 42.9-46.5 vs. VKAs = 51, 49.2-52.8, p < 0.0001) as the daily-life limitations, hassles and burdens and the psychological impact were less important than in patients on VKAs therapy. CONCLUSIONS VKAs negatively influence the daily-life of the patients in terms of both less satisfaction and time-consuming tasks. DOACs confer a better quality of life even if some concerns emerge from not knowing how their therapy is working.

Abstract
Introduction Anticoagulation monitoring is a major practical and clinical challenge. We assessed the performance of the microINR system in patient self-testing (PST). Methods This study was performed at four US medical centers. After the training visit of warfarin anticoagulated patients ( n = 117) on microINR system, PST was performed at home and in two visits to the medical centers. At the medical centers, both PST and healthcare professionals (HCPs) performed duplicate tests with the microINR System. A venous blood sample for the laboratory testing was also extracted. Accuracy and precision were assessed. Results The comparison between microINR PST results and microINR HCP results revealed an equivalence with a slope of 1.00 (95% confidence interval [CI]: 1.00-1.00), and an intercept of 0.00 (95% CI: 0.00-0.00). When compared with the laboratory analyzer, microINR PST results also showed good correlation with a slope of 0.94 (95% CI: 0.86-1.04) and an intercept of 0.14 (95% CI: -0.09-0.34). Predicted bias values at international normalized ratio (INR) 2.0, 3.5, and 4.5 were 0% against HCP and ≤2.5% against the laboratory. Analytical agreement with both HCP and laboratory was 100% according to ISO17593 and 99.1 and 100% according to CLSI POCT14 with HCP and laboratory, respectively. Clinical agreement with HCP regarding 2.0-4.0 as INR therapeutic range was 98% (within range). The precision (coefficient of variation) of microINR system used by PST was comparable to HCP. Conclusion The microINR results when used by self-testing patients show satisfactory concordance to both HCP results and laboratory analyzer. The microINR system is adequate for self-testing use.

Patient Prefer Adherence 2022; 16:2031-2039. [PMID: 35975172 PMCID: PMC9375998 DOI: 10.2147/ppa.s372366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 07/16/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND The use of point-of-care tests (POCTs) has been a central strategy to cope with the COVID-19 pandemic. Yet, evidence on the application and consequences of POCTs within medical settings is rare. PURPOSE To assess and understand patient perspectives on molecular point-of-care SARS-CoV-2 testing conducted in primary care. METHODS We conducted a cross-sectional survey study among patients who were tested with a molecular SARS-CoV-2 rapid test (ID NOWTM COVID-19 rapid test, Abbott) in 13 primary care practices in the state of Thuringia (Germany) from February to April 2021. The following aspects were covered in the questionnaire through rating scales and open text formats: test characteristics, trust in test result, consequences of immediate result, cost amount willing to pay and expectations in the future. Open text answers were categorized; quantitative data were analyzed using descriptive statistics and a Mann-Whitney U-test to reveal differences in cost contribution depending on the test result. RESULTS A total of 215 patients from nine family practices and one pediatric practice participated. The immediate availability of the test result was important to the majority of patients (94.3%). 95.7% of patients trusted in their test result. Personal consequences of the immediate test result referred to pandemic measures, certainty of action and reassurance. For further tests, patients were willing to pay between 0€ and 100€ (interquartile range = 10-25€) for the molecular SARS-CoV-2 POCT, regardless of the test result. Expectations of being offered the test again in case of renewed cold symptoms were reported by 96.2%. CONCLUSION Patients highly appreciated molecular SARS-CoV-2 rapid testing conducted in primary care practices. The immediate availability of the test result led to adjustments in patients' behavior and emotional wellbeing. However, potentially challenging for the implementation of POCTs in primary care practices may be the reimbursement of test costs and patients' expectations in future situation.

Abstract
Point-of-care testing (POCT) performed by the patient at home, paired with eHealth technologies, offers a wealth of opportunities to develop individualized, empowering clinical pathways. The non-dialysis-dependent chronic kidney disease (CKD) patient who is at risk of or may already be suffering from a number of the associated complications of CKD represents an ideal patient group for the development of such initiatives. The current coronavirus disease 2019 pandemic and drive towards shielding vulnerable individuals have further highlighted the need for home testing pathways. In this narrative review we outline the evidence supporting remote patient management and the various technologies in use in the POCT setting. We then review the devices currently available for use in the home by patients in five key areas of renal medicine: anaemia, biochemical, blood pressure (BP), anticoagulation and diabetes monitoring. Currently there are few devices and little evidence to support the use of home POCT in CKD. While home testing in BP, anticoagulation and diabetes monitoring is relatively well developed, the fields of anaemia and biochemical POCT are still in their infancy. However, patients' attitudes towards eHealth and home POCT are consistently positive and physicians also find this care highly acceptable. The regulatory and translational challenges involved in the development of new home-based care pathways are significant. Pragmatic and adaptable trials of a hybrid effectiveness-implementation design, as well as continued technological POCT device advancement, are required to deliver these innovative new pathways that our patients desire and deserve.

Patients' adherence to oral anticoagulants therapy: Comparison between vitamin K antagonists and direct oral anticoagulants. Int J Cardiol 2021; 333:162-166. [PMID: 33705844 DOI: 10.1016/j.ijcard.2021.03.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 02/25/2021] [Accepted: 03/01/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Patient's adherence to oral anticoagulant therapy is essential to prevent and treat thrombotic events. METHODS To assess the patients' adherence Morisky Medication Adherence Scale 8-items was used. The target population included 785 consecutive outpatients, of whom 384 were on Vitamin K Antagonists and 401 on Direct Oral Anticoagulants. Moreover, we evaluate which variable among age, gender, having experienced a thrombotic episode, time in the therapeutic range for patients on Vitamin K Antagonists, being naive and once versus twice daily drug assumption for patients on Direct Oral Anticoagulants, could affect adherence to therapy. RESULTS Morisky Medication Adherence Scale 8-items score was 8 in both groups. The intentional non-adherence obtained the lowest score while the unintentional non-adherence is the most frequent problem in patients treated with either Vitamin K Antagonists or Direct Oral Anticoagulants. Age > 75 years, male gender, having experienced a thrombotic episode, being naive and assuming Direct Oral Anticoagulants twice a day were significantly associated with a higher risk to forget assuming the oral anticoagulant, to have more difficulty in remembering to take it or to bring it in case of travel or leaving home. A low percentage of time in therapeutic range was associated with a not regularly assumption of the anticoagulants. CONCLUSION Patients treated with Vitamin K Antagonists or Direct Oral Anticoagulants show a good adherence and persistence to their oral anticoagulant therapy. Several factors have been identified to affect patients' adherence and deserve a careful attention by the doctors at the Anticoagulation Clinic.

Abstract
BACKGROUND Anticoagulatory activity of direct oral anticoagulants (DOACs) is not routinely measurable by point-of-care monitoring. Thus, the aim of this study was to evaluate the influence of dabigatran/rivaroxaban on point-of-care testing. METHODS Samples from 34 participants under DOAC therapy were drawn at two time points. Before ingestion and two-to-three hours afterwards. Thrombelastometric (ROTEM) and aggregometric (Multiplate) measurements were performed. Dabigatran and rivaroxaban plasma levels were determined. RESULTS Dabigatran and rivaroxaban plasma levels showed significant correlations with clotting time (CT) in EXTEM (r=0.765, P<0.0001; r=0.689, P<0.0001) and INTEM (r=0.792, P<0.0001; r=0.595, P<0.001). A positive correlation was identified between dabigatran ingestion and maximum-clot-firmness (MCF) (r=0.354, P<0.05) in the EXTEM test, pronounced in the absence of concomitant antiplatelet therapy (r=0.709, P<0.05). EXTEM-MCF positively correlated with the TRAP test in aggregometry (0.662, P<0.05), an effect not observed in patients treated with antiplatelet therapy. CONCLUSIONS Prolongation of CT-EXTEM and CT-INTEM indicates delayed initiation of clot formation. The CT-EXTEM seems to facilitate qualitative monitoring of dabigatran. In contrast, qualitative monitoring of rivaroxaban by CT-EXTEM may be limited as rivaroxaban may affect the measurement at therapeutic plasma levels. It seems that clot formation is faster/firmer in the presence of increased dabigatran plasma levels. This can be attributed to a non-dose-dependent effect via increased fibrin polymerization and second to a dose-dependent effect via increased platelet sensitivity to thrombin.

Abstract
BACKGROUND The exact monitoring of the therapeutic-range international normalized ratio (INR) after left ventricular assist device (LVAD) implantation is an important aim to reduce the risk of thrombosis or bleeding complications. Service providers offer a telemedical anticoagulation service (CS). METHODS We compared LVAD patients using the CS (n = 15) to those who received regular medical care (RMC; n = 15) to investigate if telemedicine supervision increased the INR-specific time in the therapeutic range (TTR) during anticoagulation. All patients received self-management training for phenprocoumon medication according to their INR value. INR values were documented for 12 months. A survey (scale: 1 = not satisfied and 10 = very satisfied) was used to determine patient's satisfaction and psychological well-being. RESULTS A total of 1,798 INR measurements were analyzed. The TTRRosendaal was higher in patients undergoing RMC (78.1 ± 14.3%) compared with that in patients using the CS (58.3 ± 28.0%, p = 0.03). The patient's satisfaction with the coagulation setting at the beginning of the study (RMC: 6.7 ± 3.1, CS: 7.2 ± 3.0, p = 0.74) and psychological wellbeing (RMC: 6.5 ± 1.9, CS: 6.5 ± 2.7, p = 0.97) were comparable between both groups. CONCLUSION We found that INR self-management is superior regarding the efficiency of post-LVAD anticoagulation therapy when compared with telemedical (CS)-based INR management in a small study cohort. Intensive training by experienced staff was able to replace CS.

Abstract
Vitamin K-Antagonists (VKAs) are the treatment of choice in patients with indications other than atrial fibrillation and venous thromboembolism. Moreover, some patients still assume VKAs refusing to change their therapy when direct oral anticoagulants (DOACs) are properly indicated. The COVID-19 pandemic has completely changed our lives, nullifying inter-personal relationships to avoid contagion, making difficult the VKAs monitoring. We describe the re-organization of our thrombosis centre (TC) as an example on how to face the emergency due to the COVID-19 pandemic. In the first phase, to avoid overcrowding at the TC, we planned to increase the interval time between INRs checks and to encourage blood sampling at home, especially for elderly patients. Moreover, precise scheduled blood sampling was also organized while telephone and email counselling were guaranteed by two doctors of the TC. In the second phase, to reduce the number of patients who daily attended our TC a switch from VKAs to DOACs was carried out, if no contraindications were identified. In the third phase, to protect patients, healthcare staff and hospital from COVID-19 widespread, telemedicine was strengthened. We tried to extend self-testing at home by means of portable coagulometers to as more patients as possible. To avoid patients staying or coming back to the TC an ad hoc web platform for sending the therapeutic dose adjustment and the next scheduled appointment was developed. The TC re-organization allowed us to monitor anticoagulated patients respecting personal isolation and security measures to avoid possible COVID-19 contagion.

Patients' satisfaction associated with portable coagulometers for warfarin monitoring: a cross-sectional study. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2020; 18:386-395. [PMID: 32530403 DOI: 10.2450/2020.0005-20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Accepted: 04/07/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND The use of point-of-care (POC) coagulometers for monitoring patients on vitamin K antagonist (VKA) treatment makes international normalised ratio (INR) results immediately available. The aim of this study was to compare patients' satisfaction with VKA treatment in two settings characterised by distinct ways of monitoring: POC INR versus laboratory INR. MATERIALS AND METHODS We recruited adult patients on long-term warfarin treatment (July 2017-February 2018) from the Anticoagulation Clinics at five district health centres (namely Cospicua, Floriana, Mosta, Qormi, Rabat-POC INR) and at Mater Dei Hospital (Msida - Laboratory INR) in Malta. We administered two psychometric questionnaires: the Duke Anticoagulation Satisfaction Scale (DASS) (range 25-175, lower scores corresponding to higher satisfaction) and the Perception of Anticoagulation Treatment Questionnaire (PACT-Q2) (range 0-100, higher scores corresponding to higher satisfaction). RESULTS We analysed 313 questionnaires (POC INR n=159, laboratory INR n=154). In the POC INR cohort, median age was 72 years and 59.1% were males; in the laboratory INR cohort, median age was 70.5 years and 46.1% were males. The POC INR cohort obtained significantly lower overall DASS score (p<0.001) and significantly higher PACT-Q2 scores (p<0.001 for the subscale "convenience"; p=0.039 for the subscale "anticoagulant treatment satisfaction") than the laboratory INR cohort. In multiple regression analysis, the use of POC coagulometers was significantly associated with the overall DASS score (p=0.013) and the PACT-Q2 convenience score (p=0.012). DISCUSSION Patients on warfarin treatment were generally satisfied. Patients monitored with the POC INR with a dedicated time slot reported less inconvenience and burdens and better psychological impact than patients monitored with the traditional laboratory INR.
