    Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

    BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

    El dolor se ha convertido en el quinto signo vital (1-3) y es hoy día un tema crítico en la atención del paciente. El tratamiento eficaz del mismo sigue siendo uno de los problemas más importantes y urgentes del sistema de asistencia sanitaria de los países desarrollados de todo el mundo. Si bien el dolor en los pacientes es un tema muy en boga actualmente, sin embargo, lo que es poco cuestionado es la formación de los futuros profesionales de Enfermería en el cuidado de dichos pacientes. El estudio y el tratamiento del dolor deberían ser inculcados en los estudiantes de Enfermería dentro de su formación, tanto teórica como práctica. Es muy importante la labor que asumen también los docentes en el tema. El reto para la profesión de Enfermería consistiría en este terreno en que organice, estructure y apoye un programa consistente en la activación de programas docentes para estudiantes y enfermeros en ejercicio. Para iniciar nuestro trabajo de investigación realizamos un análisis por una parte, de los actuales programas curriculares de las distintas escuelas de enfermería de la CAM, con asignaturas con contenidos en dolor, analizándose la similitud o no entre ellos, los epígrafes tratados, etc., todo ello comparado con el esbozo curricular que la IASP (International Association of Study of Pain) propuso para los estudios de enfermería; y por otra, se describen los conocimientos y las actitudes de ambos grupos en enfermería ante el dolor, tanto profesionales como estudiantes de enfermería. Para observar el grado de conocimientos y actitudes ante el dolor de ambos grupos, se introdujo como herramienta el NKAS-RP (Nurses' Knowledge and attitudes Survey Regarding Pain) (4). El grupo de trabajo se propuso, por tanto, tres objetivos generales: el primero, descripción de los temarios de las asignaturas de la carrera de enfermería con contenidos en dolor, y el 2.º y 3.º objetivos, definir los conocimientos y las actitudes ante el dolor de los estudiantes de enfermería y de los profesionales enfermeros de la CAM. Se trata de un estudio descriptivo, observacional, aleatorio y multicéntrico, que analiza los conocimientos actuales, así como las actitudes del grupo de enfermería, tanto entre estudiantes (futuros diplomados en enfermería) como entre profesionales. Se llevó a cabo entre los años 2008 al 2010, utilizándose para dar a conocer los resultados del mismo el paquete estadístico SPSS versión 17.0. Como resultados, se obtuvieron, al igual que en estudios previos, a nivel mundial, unos pobres conocimientos en dolor y unas malas actitudes ante dicho síntoma. Se propone para mejorarlos, en el caso de los estudiantes, cambios en los programas curriculares de la diplomatura (futuro grado) de enfermería, y en el caso de los profesionales, formación continuada, así como actualización de conocimientos en dicho tema.The pain has become the fifth vital sign and is now a critical issue in patient care. Effective treatment of it is still one of the most important and urgent health care system in developed countries worldwide. While pain in patients is a very in vogue these days, however, which is unchallenged is the education of future nursing professionals in the care of such patients. The study and treatment of pain should be instilled in nursing students in their training, both theoretical and practical. The work is very important that teachers also take on the subject. The challenge for the nursing profession in this field would you organize, structure and support a program involving the activation of educational programs for students and practicing nurses. To start our research we made an analysis on the one hand, the current curricula of different schools of nursing in the CAM, with subjects with pain content, analyzing the similarity or not between them, the treated sections, etc. all this curriculum outline compared to the IASP (International Association of Study of Pain) proposed for nursing studies and, secondly, we describe the knowledge and attitudes of both groups in nursing to pain, both professional and qualified nurses. To observe the degree of knowledge and attitudes towards pain in both groups, was introduced as a tool the NKAS-RP (Nurses' Knowledge and Attitudes Survey Regarding Pain). The working group is proposed, therefore, three general objectives: The first description of the curricula of the courses in the career of nursing content in pain, and el2 and 3 goals, define the knowledge and attitudes to pain nursing students and nurses of the CAM. This is a descriptive, observational, multicenter, randomized, which analyzes the current knowledge and attitudes of the nursing staff, both among students (future graduates in nursing) and among professionals. Was carried out between 2008 and 2010, used to publicize the results of the statistical package SPSS version 17.0. As results were obtained, as in previous studies, worldwide, a poor knowledge of pain and a bad attitude before that symptom. It is proposed to improve: in the case of students, changes in the curriculum of the Diploma (future degree) nurses, and in the case of professionals, continuing education and refresher courses in that subject

    Background-—Using data from the GARFIELD-AF (Global Anticoagulant Registry in the FIELD–Atrial Fibrillation), we evaluated the impact of chronic kidney disease (CKD) stage on clinical outcomes in patients with newly diagnosed atrial fibrillation (AF). Methods and Results-—GARFIELD-AF is a prospective registry of patients from 35 countries, including patients from Asia (China, India, Japan, Singapore, South Korea, and Thailand). Consecutive patients enrolled (2013–2016) were classified with no, mild, or moderate-to-severe CKD, based on the National Kidney Foundation’s Kidney Disease Outcomes Quality Initiative guidelines. Data on CKD status and outcomes were available for 33 024 of 34 854 patients (including 9491 patients from Asia); 10.9% (n=3613) had moderate-to-severe CKD, 16.9% (n=5595) mild CKD, and 72.1% (n=23 816) no CKD. The use of oral anticoagulants was influenced by stroke risk (ie, post hoc assessment of CHA2DS2-VASc score), but not by CKD stage. The quality of anticoagulant control with vitamin K antagonists did not differ with CKD stage. After adjusting for baseline characteristics and antithrombotic use, both mild and moderate-to-severe CKD were independent risk factors for all-cause mortality. Moderate-to-severe CKD was independently associated with a higher risk of stroke/systemic embolism, major bleeding, new-onset acute coronary syndrome, and new or worsening heart failure. The impact of moderate-to-severe CKD on mortality was significantly greater in patients from Asia than the rest of the world (P=0.001). Conclusions-—In GARFIELD-AF, moderate-to-severe CKD was independently associated with stroke/systemic embolism, major bleeding, and mortality. The effect of moderate-to-severe CKD on mortality was even greater in patients from Asia than the rest of the world

    Predictors of NOAC versus VKA use for stroke prevention in patients with newly diagnosed atrial fibrillation: Results from GARFIELD-AF

    No full text
    Introduction A principal aim of the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) was to document changes in treatment practice for patients with newly diagnosed atrial fibrillation during an era when non-vitamin K antagonist oral anticoagulants (NOACs) were becoming more widely adopted. In these analyses, the key factors which determined the choice between NOACs and vitamin K antagonists (VKAs) are explored
