Not included in the model were body mass index, hemoglobin A1c, ethnicity, and ex-smoking status. Results- Variables included in the final model were duration of diabetes, age, sex, smoking, systolic blood pressure, total cholesterol to high-density lipoprotein cholesterol ratio and presence of atrial fibrillation. Diagnostic plots were used to compare survival probabilities calculated by the model with those calculated using nonparametric methods. Model fitting was carried out by maximum likelihood estimation using the Newton-Raphson method. Methods- During 30 700 person-years of follow-up, 188 first strokes (52 fatal) occurred. We developed mathematical models to estimate the risk of a first stroke using data from 4549 newly diagnosed type 2 diabetic patients enrolled in the UK Prospective Diabetes Study. Relative risks have been examined in earlier work, but there is no readily available method for predicting the absolute risk of stroke in a diabetic individual. Customer Service and Ordering Informationīackground and Purpose- People with type 2 diabetes are at elevated risk of stroke compared with those without diabetes.Stroke: Vascular and Interventional Neurology.Journal of the American Heart Association (JAHA). ![]() Circ: Cardiovascular Quality & Outcomes.Arteriosclerosis, Thrombosis, and Vascular Biology (ATVB).It includes most of the components of diabetes audit required by the National Service Framework (NSF) and the United Kingdom GP contract. The Alphabet Practice Of Evidence-based Medicine (POEM) template is a useful clinical tool for diabetes care and audit. 16.4% (Tfu): p < 0.0001).Ĭonclusions:The Alphabet Strategy is a novel evidence-based approach to clinical diabetes care, which produced a statistically significant improvement in most of the assessed parameters. 16.4% ( Tfu): p < 0.001), with a significant deterioration noted between T0 and Tfu (11.5% (T0) vs. For UKPDS stroke risk, a significant improvement was seen from Tadj to Tfu (19.0% ( Tadj) vs. There were significant improvements between age-adjusted risk score ( Tadj) and follow-up values ( Tfu) (Framingham: 23.67% ( Tadj) vs. Using the UKPDS risk engine, there was a non-significant reduction in absolute CHD risk over the follow-up period (23.8 ± 14.8% vs. Heart disease risk scores: a significant reduction in Framingham 10-year absolute cardiac risk was achieved (20.6 ± 10.04% vs. 83.5%: p < 0.001), angiotensin converting enzyme (ACE) inhibitors (32.0 vs. Guardian drugs: significantly more patients were on aspirin (29.0 vs. However, when adjusted for duration of diabetes, this improved non-significantly by 12% overall. Diabetes control: glycated haemoglobin (HbA1c)% worsened 7.9 ± 1.8 vs. 4.9 ± 1.0 mmol/L: p < 0.0001 high density lipoprotein (HDL) cholesterol improved 1.05 vs. Cholesterol: total cholesterol improved 5.8 ± 1.6 vs. Diastolic blood pressure improved 82.0 ± 12.2 vs. Blood pressure: systolic blood pressure improved 145.8 ± 21.1 vs. Results ( T0 vs.Tfu): Advice: smoking status improved 18.3 vs. The results were analysed using Student's paired t-test and chi-squared test. Absolute CHD risk was calculated using the Framingham risk function and the United Kingdom Prospective Diabetes Study (UKPDS) risk engine. The average follow-up period was 5 years. The subjects were men and women aged 21-75 years with necessary follow-up data from referral or first chronological available letter in the notes ( T0) to the most recent follow-up visit ( Tfu). Methods: Diabetes and cardiovascular parameters were collected on 400 consecutive type 2 diabetes patients attending the outpatient clinic. Aims: To assess the impact of evidence-based strategies on the care of subjects with diabetes, in particular on their coronary heart disease (CHD) risk, using the Alphabet Strategy template and coronary heart disease (CHD) risk calculators as novel audit tools. ![]()
