RESUMEN

BACKGROUND: The prevalence of type 2 diabetes is rising, and most of these patients also have hypertension, substantially increasing the risk of cardiovascular morbidity and mortality. The majority of these patients do not reach target blood pressure levels for a wide variety of reasons. When a literature review provided no clear focus for action when patients are not at target, we initiated a study to identify characteristics of patients and providers associated with achieving target BP levels in community-based practice. METHODS: We conducted a practice-based, cross-sectional observational and mailed survey study. The setting was the practices of 27 family physicians and nurse practitioners in 3 eastern provinces in Canada. The participants were all patients with type 2 diabetes who could understand English, were able to give consent, and would be available for follow-up for more than one year. Data were collected from each patient's medical record and from each patient and physician/nurse practitioner by mailed survey. Our main outcome measures were overall blood pressure at target (< 130/80), systolic blood pressure at target, and diastolic blood pressure at target. Analysis included initial descriptive statistics, logistic regression models, and multivariate regression using hierarchical nonlinear modeling (HNLM). RESULTS: Fifty-four percent were at target for both systolic and diastolic pressures. Sixty-two percent were at systolic target, and 79% were at diastolic target. Patients who reported eating food low in salt had higher odds of reaching target blood pressure. Similarly, patients reporting low adherence to their medication regimen had lower odds of reaching target blood pressure. CONCLUSIONS: When primary care health professionals are dealing with blood pressures above target in a patient with type 2 diabetes, they should pay particular attention to two factors. They should inquire about dietary salt intake, strongly emphasize the importance of reduction, and refer for detailed counseling if necessary. Similarly, they should inquire about adherence to the medication regimen, and employ a variety of patient-oriented strategies to improve adherence.

RESUMEN

OBJECTIVE: To describe the number and classes of antihypertensive medications prescribed to patients with type 2 diabetes in community family practices, and to estimate the aggressiveness or "dosage intensity" of prescribing for hypertension in these situations. DESIGN: Practice-based, cross-sectional observational study. SETTING: Seventeen rural and urban family practices in the Maritime Family Practice Research Network in Nova Scotia, New Brunswick, and Prince Edward Island. PARTICIPANTS: A total of 670 patients with type 2 diabetes, ranging from 25 to 92 years of age. MAIN OUTCOME MEASURES: Number, classes, and combinations of classes of antihypertensive medications prescribed, as well as an index of each medication's dosage intensity. RESULTS: Almost 80% of patients studied had hypertension. Participants with hypertension were taking an average of 2.5 medications, and 47.6% were taking 3 or more antihypertensive medications, but only 27.1% reached target blood pressure values of less than 130/80 mm Hg. Older patients took more antihypertensive medications, but there were no differences by sex. More than 90% were taking angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, 66% were taking diuretics, 41% were taking beta-blockers, and 38% were taking calcium channel blockers. We cannot describe the sequence in which antihypertensive medication classes were added, but analysis of patients taking multiple drug classes suggests that most patients were started on angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, followed by diuretics, beta-blockers, or calcium channel blockers. The most commonly used medications were prescribed at higher than two-thirds the maximum dose effective for hypertension. CONCLUSION: Hypertension is very common among family practice patients with type 2 diabetes; of those patients, few reach target blood pressures. Practice-based strategies to increase dosing and number of medications prescribed might be required.
