Abstract
Abstract Background About 55% of the population 40 to 80 years of age in Barbados is hypertensive. The quality of hypertension primary care compared to available practice guidelines is uncertain. Findings Charts of hypertensive and diabetic patients were randomly sampled at all public and 20 private sector primary care clinics. Charts of all hypertensive patients and#8805; 40 years of age were then selected and processes of care and blood pressure (BP) maintenance andlt; 140/90 documented. 343 charts of hypertensive patients (170 public, and 173 private) were audited. Patients had the following characteristics: mean age 64 years, female gender 63%, mean duration of diagnosis 9.1 years, and diabetes diagnosed 58%. Patients had an average of 4.7 clinic visits per year, 70% were prescribed a thiazide diuretic, 42% a calcium channel blocker, 40% an angiotensin receptor blocker, and 19% a beta blocker. Public patients compared to private patients were more likely to be female (73% vs. 52%, p andlt; 0.01); have a longer duration of diagnosis (11.7 vs. 6.5 years, p andlt; 0.01), and more clinic visits per year (5.0 vs. 4.5, p andlt; 0.01). Over a 2 year period, the proportion of charts with the following recorded at least once was: BP 98%, weight 80%, total cholesterol 71%, urine tested for albumin 67%, serum creatinine 59%, dietary advice 55%, lipid profile 48%, exercise advice 45%, fasting blood glucose for non-diabetics 39%, dietician referral 21%, tobacco advice 17%, retinal examination 16%, body mass index 1%, and waist circumference 0%. Public patients were more likely to have recorded: weight (92% vs. 68%, p = andlt; 0.01); tests for total cholesterol (77% vs. 67%, p = 0.04), albuminuria (77% vs. 58%, p = andlt; 0.01), serum creatinine (75% vs. 43%, p andlt; 0.01), and fasting blood glucose for non-diabetics (49% vs. 30%, p = 0.02); dietician referral (34% vs. 9%, p andlt; 0.01), and tobacco advice (24% vs. 10%, p andlt; 0.01). Most (92%) diastolic BP readings ended in 0 or 5 (72% ended in 0). At the last visit 36% of patients had a BP andlt; 140/90 mmHg. Conclusions Improvements are needed in following guidelines for basic interventions such as body mass assessment, accurate BP measurement, use of thiazide diuretics and lifestyle advice. BP control is inadequate.
