Abstract
Our objective was to determine the rate of hypertensive patients with controlled BP (BP < 140 x 90 mmHg) and to study its relationship with regular attendance to ambulatory appointments. A total of 245 medical records from patients followed up at the Unidade Clínica de Hipertensão Arterial (Clinical Unit of Arterial Hypertension) HCFMRP-USP for a period of one year were randomly and retrospectively reviewed. The patients were classified as assiduous (A) and as regularly absent to scheduled appointments (F), with the second group being defined as those who failed to appear longer than 30 days after the scheduled appointment. The mean of three measurements prior to the date of the scheduled appointment was calculated to determine the rate of patients with controlled BP. Compliance with the treatment was inferred through a questionnaire applied by the nurse team before the appointment. From the 245 patients analyzed, 220 were classified as A (89.7%) and 25 (10.3%) as F. Group A patients showed a higher rate of BP control than F patients (30% vs. 8%, p = 0.02, Fischer exact test). Compliance with pharmacological treatment was higher in A patients than in F patients (91% vs. 56 %, p < 0.05) as well as to non-pharmacological treatment (63% vs. 44%, p < 0.05). Although the rate of blood pressure control was low in the population studied, lower compliance with the treatment and BP control was observed in individuals who usually missed the scheduled appointments.
