Characteristics and Factors Associated With Antihypertensive Medication Use in Patients Attending Peruvian Health Facilities

Introduction 

Hypertension is a very common disease worldwide, and medication is needed to prevent its short-term and long-term complications. Our objective was to determine the characteristics and factors associated with antihypertensive medication use in patients attending Peruvian health facilities.

Materials & Methods

We performed a multicenter, cross-sectional study with secondary data. We obtained self-reported antihypertensive medication from patients attending health facilities in 10 departments of Peru. We looked for associations of the antihypertensive treatment according to sociopathological factors and obtained p values using generalized linear models.

Results

Of the 894 patients with hypertension, 61% (547) were women and 60% (503) were on antihypertensive treatment, of which 82% (389) had monotherapy and 52% (258) had recently taken their medication. Antihypertensive treatment was positively correlated with the patient's age (adjusted prevalence ratio [aPR]: 1.01; 95% confidence interval [CI]: 1.007 to 1.017; p value < 0.001), diabetes (aPR: 1.31; 95% CI: 1.11 to 1.55; p value = 0.001) and cardiovascular disease (aPR: 1.38; 95% CI: 1.26 to 1.51; p value < 0.001). Conversely, the frequency of antihypertensive treatment decreases with physical activity (aPR: 0.80; 95% CI: 0.70 to 0.92; p value = 0.001).

Conclusion

Patients who have comorbidities and advanced age are more likely to be on antihypertensive treatment. In contrast, patients with increased physical activity have a lower frequency of antihypertensive treatment. It is important to consider these factors for future preventive programs and to improve therapeutic compliance.

[Vascular risk in outpatient from Internal Medicine departments. MICARE Study]

BACKGROUND AND OBJECTIVES

The population attended in the Spanish Internal Medicine departments is of increasing age, but the prevalence of vascular risk factors and its degree of control are unknown, as well as the differences by type of hospital or consulting room.

PATIENTS AND METHODS

Epidemiologic, transversal and metacentric study in patients ≥ 18 years treated in outpatient Internal Medicine hospital. Two-hundred and ninety physicians from 17 Autonomic Communities participated in the study. The type of hospital or consulting room was also recorded. Blood pressure control was defined as <140/90 mm Hg (<130/80 mm Hg in diabetics or patients with vascular disease), LDL-cholesterol control when<130 mg/dl (<100mg/dl in diabetic or vascular disease) and diabetes control if glycated hemoglobin was<7%.

RESULTS

Data from 2,704 patients was collected (54% men) mean age (SD) 64,1 (14,5) years. Ninety-three percent of them had at least one cardiovascular risk factor: hypertension 73.9%, dyslipidemia 59.5%, abdominal obesity 43.4%, diabetes 39.5%. Fifty percent had some target organ damaged, 46.7% showed vascular disease and 71.2% a high or very high vascular risk. Control over risk factors was: hypertension 33.8%, cholesterol-LDL 40.8% and diabetes 50.7%. There were no differences between type of hospital or type of outpatient consultancy.

CONCLUSIONS

Over 90% of patients treated in outpatient consultancies of Internal Medicine departments present vascular risk factors, regardless of the type of hospital or type of consulting room. Risk factors control was poor.
