Cardiovascular diseases are the leading cause of death worldwide, and a key risk factor for these diseases—hypertension—is unquestionably the most prevalent disease in the population.11.

Cardiovascular semiology is extremely important in the setting of hypertension (HTN), since the determination of blood pressure values through established indirect measurement techniques plays an essential role in initiating further diagnostic investigation, prompting treatment, and allowing monitoring of patients with HTN. The environment in which measurement is performed; the patient’s dietary habits, use of tobacco and alcohol, and engagement in physical activity before measurement; the adequacy of cuff size in relation to the limb; and proper cuff positioning are among the several important aspects which may interfere with measurement reliability. In this context, assessing the technical knowledge of healthcare providers is critical to preventing diagnostic errors.22. Malachias MVB, Souza WKSB, Plavnik FL, Rodrigues CIS, Brandão AA, Neves MFT, et al. 7ª Diretriz Brasileira de Hipertensão Arterial. Arq Bras Cardiol 2016; 107(3Supl.3):1-83.

Differences in magnitude between office BP and mean daytime BP can be attributed both to the environment and to the technical quality of blood pressure measurement by the examiner. Beckett et al. obtained an average of three manual BP readings from 481 hypertensive patients in family practices. The average clinic BP (151/83 mmHg) was significantly (P<0.001) higher than the daytime mean BP measured by ambulatory blood pressure monitoring (ABPM) (142/80 mmHg).33. Beckett L, Godwin M.

Blood Press Monit. 2006;11(3):111-8. doi:10.1097/01.mbp.0000209086.32493.bd in a study with almost 6,000 patients, encouraged family physicians to perform 24-hour ABPM in the largest possible number of patients versus manual blood pressure measurement by the study physician. The average of three readings recorded manually in the office before ABPM was 164/96 mmHg, compared to a mean daytime ABPM of 149/90 mm Hg. In another series of 309 patients referred for 24-hour ABPM, the last office BP (recorded manually) was 152/87 mmHg, significantly (P<0.001) higher than the mean daytime BP recorded by ABPM (134/77 mmHg). Data from these studies show a consistent difference of up to 5 mmHg between daytime ABPM and routine office BP. This is a relevant finding, because this difference can be attributed at least partly to measurement errors secondary to poor semiologic technique.55. Myers MG, Valdivieso M, Kiss A.

This was a quantitative, observational, cross-sectional study of 80 providers observed from August 2013 to January 2014. The results showed high rates (93.8 to 100%) of of failure to perform the preparatory stages of blood pressure measurement (i.e., preparing the patient before the actual measurement is taken). Sphygmomanometer calibration was not checked, and there were no different cuff sizes available. The authors concluded that there are significant gaps in the procedures adopted by nursing providers to measure blood pressure, indicating a need for corrective educational measures.

in this issue aims to evaluate the theoretical and practical knowledge of blood pressure measurement technique among health professionals before and after an educational intervention. Among the providers evaluated, significant rates of improvement in the blood pressure measurement technique were observed after the educational intervention. These findings reflect that educational interventions and training in proper semiologic technique for blood pressure measurement semiotics are important actions in the Brazilian context, considering their impact on the diagnosis and treatment of HTN in this population.
