Anticoagulant usage for primary stroke prevention: a general practitioner survey in local areas of metropolitan Sydney.

We assessed the hypothesis that having a non-English-speaking background (NESB), being very elderly, living alone, and having cognitive impairment were contributing factors to anticoagulant under-utilisation for atrial fibrillation in our local community. A questionnaire was mailed to 532 general practitioners (GPs) in three areas of metropolitan Sydney, Australia. The questionnaire included five case scenarios, regarding either an English-speaking background (ESB) patient, or an NESB patient, each characterised by potential barrier(s) for anticoagulant usage: being (1) elderly; (2) elderly with mild dementia; (3) elderly with mild dementia and living alone; (4) elderly with severe dementia; and (5) very elderly. The overall response rate was 34%. The percentage of GPs recommending anticoagulation was 57%, 50%, 6%, 25% and 23%, respectively, for the ESB scenario, and 48%, 32%, 4%, 14% and 18%, respectively, for the NESB scenario. Eighty-eight percent of GPs rated 'adherence to International Normalized Ration monitoring' as 'very important' in their decision. In conclusion, the factors proposed in our hypothesis were associated with a lower likelihood for anticoagulant prescription for atrial fibrillation.

Comparison of stroke risk factors and outcomes in patients with English-speaking background versus non-English-speaking background.

This study examined stroke risk factor profiles, management and outcomes for elderly patients with English-speaking background (ESB) and non-English-speaking background (NESB). This is an observational cohort study with both retrospective and prospective components. In total, 186 consecutive acute stroke patients aged > or =65 years admitted to our hospital were recruited over a 12-month period. Patient characteristics, stroke risk factors and management, in-hospital mortality, functional independence measurement scores before admission and at discharge, and discharge destination were recorded. On admission, NESB patients with atrial fibrillation (AF) were less likely to be taking warfarin than ESB patients (1 out of 19 with NESB vs. 19 out of 41 with ESB, p = 0.001). More NESB patients had a history of diabetes mellitus (DM) than ESB patients (41.4 vs. 10.2%, respectively; p = 0.001). However, ESB and NESB patients were comparable in terms of age, gender, preadmission functional status as well as other stroke risk factors (including smoking and alcohol drinking pattern, prevalence of hypertension and lipid disorder) and their management. In-hospital mortality was similar between ESB and NESB patients (10.2 vs. 8.6%). In conclusion, we found an association with our population of elderly NESB patients and an underutilization of warfarin for AF as well as a higher frequency of DM. Determination of the underlying reasons for such differences may be of value in the primary health care of NESB patients.
