Arterial hypertension in chronic renal disease. Educational intervention in patients with stage IV / V (Polyclinic of Nephrology Hospital de Clínicas) period July-September of 2016

Abstract

The aims of the study were to evaluate the relationship between blood pressure and outcome in Chronic Kidney Disease (CKD) patients assisted at the Departamento de Nefrología del Hospital de Clínicas and perform an educational intervention to improve adherence to treatment.

The study was conducted in two stages.

A. A retrospective analysis (data from the Renal Health Program Registry), was performed to correlate blood pressure with the change outcome of patients assisted in the study period (1/7/2015-30/6/2016).

B. An educational activity was planned, implemented and evaluated with the aim of improving the Blood Pressure control, sodium intake, and physical exercise.  Hypertension prevalence was 62.8%. In the overall population, 123 patients with mean Blood Pressure ≥140/90 mmHg (of 374 individuals with more than three months of follow-up), had a significantly lower survival than the normotensive group. In the overall population the multiple linear regression analysis showed that hypertension increases the risk of RRT or death No difference was observed in the IV-V stage subpopulation (n=59). B: Educational activity Evaluation (Previous vs final) showed a significant improvement in identifying the sodium content of selected food (McNemar test, p <0.05) and a high grade of acceptance.

Conclusions: The persistence of hypertension in evolution was associated with increased risk of admission to renal replacement therapy or death. The successful; educational activity encourages to develop similar strategies, with the expectation of improving patients´ self-care behaviors and survival.
