Determinants associated with activation in patients with oral anticoagulant treatment: A cross-sectional study.

AIMS: The terms "patient activation" and "patient empowerment" are used to describe the extent to which individuals are able to manage their own healthcare. Health outcomes and quality of life improve in patients who are more active in health care. The aim of this study was to identify sociodemographic, clinical, sociological and psychological determinants associated with activation in a group of chronically anticoagulated patients. METHODS: Cross-sectional study of patients treated with oral antivitamin-k drugs attended at a specialized outpatient anticoagulant unit between November 2021 and June 2022. The main dependent variable was the level of patient activation according to the 13-item Patient Activation Measure (PAM-13). Simple and multiple linear regression models were conducted to identify the determinants associated with PAM-13 score. RESULTS: A total of 137 patients who met all the inclusion criteria were recruited for the study. The mean age was 59.6 years (SD 13.8; range 22-86) and 60.6% were male. Sixty per cent presented a level IV of activation according to the PAM-13 scale. Mean patient activation score was 73.9 (SD 15.4). The factors independently associated with significantly lower activation were: emergency department visits in the past 12 months, intermediate social risk, anxiety symptoms, stress symptoms and low self-efficacy. CONCLUSIONS: Five determinants were found to be associated with activation. Knowing the factors that modify the level of activation can help to identify subgroups of chronic anticoagulated patients who are less likely to engage in self-management and are therefore candidates for tailored educational interventions.

Lupus anticoagulant is an independent risk factor for non-thrombotic in-hospital mortality in COVID-19 patients.

BACKGROUND: Thromboembolic disease is a frequent cause of death during SARS CoV-2 infection. Lupus anticoagulant (LA) appears frequently during the acute phase of infection. It is not clear whether it is merely an epiphenomenon or whether it is related to the patients' outcome. METHODS: Prospective observational cohort of 211 patients (118 women, mean age 65 years, range: 18 to 99) hospitalized for COVID-19. All patients were tested for LA at admission and retested six months after discharge. RESULTS: The LA test was positive in 128 patients (60.7%). The survival probability at 31 days was clearly worse in the LA-positive group (60%) than in the LA-negative group (90%) (P = 0.023). This notable difference in survival was confirmed by multivariate analysis (HR 3.9, 95% CI 1.04-14.5, P = 0.04). However, it was not explained by differences in thrombotic events (three in either group, P = 0.6). LA-positive patients had higher ferritin, CRP and IL-6 levels, and lower PAFI ratio and lymphocyte and platelet counts. Six months after discharge, LA was negative in the vast majority of positive cases (94%). CONCLUSION: LA is an independent predictor of in-hospital mortality in COVID-19 patients. It is associated with inflammation and disease severity but not with thromboembolic events. This marker usually disappears at six months.

Tromboc@t Working Group recommendations for management in patients receiving direct oral anticoagulants. / Recomendaciones del Grupo Catalán de Trombosis (Tromboc@t Working Group) para el tratamiento de los pacientes que reciben anticoagulantes orales directos.

BACKGROUND AND OBJECTIVES: In recent years, direct oral anticoagulants (DOACs) have become an alternative to vitamin K antagonists (VKA) for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF) as well as for prevention and treatment of deep venous thrombosis. Pivotal trials have demonstrated non-inferiority and potential superiority compared to warfarin, which increases the options of anticoagulant treatment. In our setting, the Anticoagulant Treatment Units (ATUs) and Primary Care Centres (PCCs) play an important role in the education, follow-up, adherence control and management in special situations of anticoagulated patients. These considerations have motivated us to elaborate the present consensus document that aims to establish clear recommendations that incorporate the findings of scientific research into clinical practice to improve the quality of care in the field of anticoagulation. MATERIAL AND METHODS: A group of experts from the Catalan Thrombosis Group (TROMBOC@T) reviewed all published literature from 2009 to 2016, in order to provide recommendations based on clinical evidence. RESULTS: As a result of the project, a set of practical recommendations have been established that will facilitate treatment, education, follow-up and management in special situations of anticoagulated patients with ACODs. CONCLUSIONS: Progressive increase in the use of DOACs calls for measures to establish and homogenise clinical management guidelines for patients anticoagulated with DOACs in ATUs and PCCs.
