Abstract
INTRODUCTION: Almost 50% of the 17.5 million deaths worldwide from cardiovascular disease have been associated with systemic arterial hypertension (SAH). Into this scenario, Pharmaceutical Care (PC) has been inserted in order to improve the management of SAH and reduce its risks. OBJECTIVE: To evaluate the outcomes and healthcare assistance achieved after discharge of hypertension patients from the PC program. METHODS: This is a quasi-experimental study with historical controls. Retrospective data collection from 2006 to 2012 was begun in 2013 and included a PC program performed over one year. PC was performed in two basic units of the public health system in Ribeirão Preto-SP, Brazil, where the pharmacist followed up 104 hypertensive patients. The clinical indicators of systolic (SBP) and diastolic blood pressure (DBP), triglycerides, total-cholesterol, high and low density lipoprotein cholesterol were collected, as well as care indicators related to the number of consultations (basic, specialized and emergency care) and antihypertensive drugs used. The coronary risk of patients by the Framingham risk score was also calculated. For the analysis, the data were divided into three periods, 2006-2008 as pre-PC, 2009 as PC and 2010-2012 as post-PC. RESULTS: In the pre-PC period, 54.4%, 79.0% and 27.3% of patients presented satisfactory levels of SBP, DBP and total-cholesterol, respectively. In the post-PC period, the percentages were 93.0% for SBP and DBP [p <0.001] and 60.6% for total-cholesterol [p <0.001]. The average number of consultations per patient/year in primary care was 1.66 ± 1.43 and 2.36 ± 1.73, [p = 0.012]; and for emergency care was 1.70 ± 1.43 and 1.06 ± 0.81, [p = 0.002] in the pre-PC and post-PC periods, respectively. The pre-PC Framingham risk in the last year was 14.3% ± 10.6 and the average post-PC was 10.9% ± 7.9. CONCLUSION: PC was effective in the control of blood pressure and total-cholesterolafter discharge of the hypertensive patients from PC program.
