[Determination of arm circumference for correct measurement of blood pressure. Results of an intervention study]. / La determinación del perímetro braquial para una adecuada medida de la presión arterial. Resultados de un estudio de intervención.

OBJECTIVE: To assess the effectiveness of an intervention to promote standardized arm circumference measurement as way to choose appropriate cuff size to measure blood pressure. PATIENTS AND METHODS: A before-after intervention study was performed in a basic health care area in Barcelona. Doctors, nurses and pharmacy staff participated by filling out an anonymous self-administered questionnaire pre- and post-intervention (3m). Variables included: demographics, type of professional, years since they finished their studies, availability of different cuff sizes, if arm circumference measurement were obtained or not, knowledge about the cutoff values for each cuff size and type of blood pressure monitor. INTERVENTION: The written results were given to the participants and presented in sessions. RESULTS: Pre- and post-intervention: 74.3 and 67.3% answered the questionnaires (P=ns), respectively. Determination of arm circumference varied from 1.3 to 19.1% (P=.009). A total of 37.3% and 44.1% declared that they had 2 or more available cuff sizes (P=ns). Knowledge about the correct measurement of the cuffs was 2.7 to 33.8% regarding the standard cuff size (P=.0198) and 0 to 23.5% for obese subjects (P<.05). When more than one cuff was available, reasons for the choice went from: «making a rough guess¼ or «when velcro stops sticking¼ before and after the intervention. All blood pressure devices in our primary health care center were electronic and automatic as were those of the 9 pharmacies. CONCLUSION: The intervention increased the determination of arm circumference prior to the reading of the blood pressure and the knowledge about the cutoff interval for standard and obese cuff size after intervention. There was greater availability of different sized cuffs. Despite this, the choice of the appropriate cuff size was not made based on arm circumference.

Objetivo: Evaluar la eficacia de una intervención para promover la determinación del perímetro braquial para seleccionar el manguito adecuado para la toma de la presión arterial. Pacientes y métodos: Estudio de intervención antes-después. Incluyó médicos, enfermeras y personal de oficinas de farmacia de un área básica de salud en Barcelona. Encuesta autoadministrada pre y posintervención (3 m). Variables recogidas: demográficas, tipo de profesional, años desde la finalización de los estudios, disponibilidad de manguitos de diferentes medidas, determinación o no del perímetro braquial, conocimiento o no de los valores de corte para cada manguito y tipo de aparatos de medida. Intervención: entrega de los resultados escritos y presentación en sesiones. Resultados: Pre y posintervención: 74,3 y 67,3% encuestas cumplimentadas (p = ns), respectivamente. La determinación del perímetro braquial varió del 1,3 al 19,1% (p = 0,009). Declararon disponer de 2 o más manguitos de diferente medida el 37,3 y el 44,1% de los encuestados (p = ns). El conocimiento del intervalo de medida correcto de los manguitos fue del 2,7 al 33,8% para el manguito estándar (p = 0,0198) y del 0 al 23,5% para el de obesos (p < 0,05). Cuando disponían de más de un manguito la elección se realizaba por motivos como «a ojo» o «cuando salta el velcro» antes y después de la intervención. La totalidad de los aparatos del centro de atención primaria eran electrónicos automáticos, así como los de 9 farmacias. Conclusión: La intervención aumentó la determinación del perímetro braquial previa a la lectura de la presión arterial y el conocimiento del intervalo de los manguitos estándar y para obesos. Hubo una mayor disponibilidad de manguitos de distinto tamaño. A pesar de ello, la utilización de uno u otro manguito no se realizaba en función de la medida del perímetro braquial

El filtrado glomerular reducido según las fórmulas de Cockcroft-Gault y MDRD no siempre predice la morbimortalidad cardiovascular en los pacientes hipertensos atendidos en atención primaria / Decreased glomerular filtration rate using the Cockgroft-Gaultand MDRD formulas does not always predict cardiovascular morbidity and mortality in hypertensive primary care patients

Antecedentes: El deterioro de la función renal se ha asociado con un incremento de la morbimortalidad cardiovascular. El objetivo del estudio fue analizar la asociación del filtrado glomerular (FG) basal, según las fórmulas de Cockcroft-Gault y MDRD, con la incidencia de eventos cardiovasculares (ECV) en una cohorte de personas hipertensas seguida durante 12 años. Métodos: Estudio prospectivo de una muestra aleatoria de 223 hipertensos libres de ECV atendidos en un centro de atención primaria urbano. Se estimó el FG mediante ambas fórmulas. Se consideró ECV la aparición de cardiopatía isquémica, insuficiencia cardíaca, accidente cerebrovascular, vasculopatía periférica o muerte por ECV. Se analizaron los datos mediante el método actuarial y modelos de regresión de Cox. Resultados: La mediana de tiempo de seguimiento fue de 10,7 años (rango intercuartílico,6,5-12,1). El seguimiento fue completo en 191 participantes (85,7%). La supervivencia acumulada fue del 64,7% (intervalo de confianza [IC] del 95%: 57,9-71,6%). La tasa media de incidencia de ECV durante todo el período de seguimiento fue de 3,6 (IC del 95%, 2,7-4,4%) por 100 personas hipertensas/año. El modelo multivariable final mostró que las variables con mayor poder predictivo de ECV en la población de estudio fueron la diabetes y la estimación del FG >60ml/min/1,73 m2mediante fórmula MDRD. Conclusiones: Se observó una relación entre la aparición de ECV y los valores de FG estimados por la fórmula MDRD al inicio del seguimiento superiores a 60 ml/min/1,73 m2, inversa a la eserada. La estimación del FG mediante fórmula de Cockcroft-Gault no se asoció con el riesgo cardiovascular (AU)

Background: Renal function decrease is associated with cardiovascular morbidity and mortality. The aim was to analyze the association of cardiovascular morbidity and mortality with baseline glomerular filtration rate (GFR), according Cockcroft-Gault and MDRD formulas, with incidence of major adverse cardiovascular events (MACEs) in a cohort of hypertensive individuals followed for 12 years. Methods: We performed a prospective study of a random sample of 223 hypertensive patients free of MACEs followed in an urban Primary Care Center. GFR was estimated using both formulas. MACEs were considered the onset of ischemic heart disease, heart failure, stroke, peripheral vascular disease or cardiovascular death. Data were analyzed using the life-table method and Cox regression modeling. Results: Follow-up median was 10.7 (interquartile range, 6.5-12.1) years. Follow-up was complete in 191 participants (85.7%). The cumulative survival was 64.7% (95%Confidence Interval (CI) 57.9%-71.6%). The incidence of MACEs during the follow-up period was 3.6 (95% CI, 2.7-4.4) per 100 subject-years. The final multivariable model showed that the most predictive variables of MACEs in the study population were the presence of diabetes and the estimation of GFR >60 ml/min/1.73 m2by MDRD equation. Conclusions: There was a relationship between the occurrence of MACEs and MDRD formula estimated GFR above60 ml/min/1.73 m2at study entry, inversely to what expected. C-G formula estimated GFR by was not associated with cardiovascular risk (AU)

BACKGROUND: A decrease in renal function is associated with cardiovascular morbidity and mortality. The aim of this study was to analyse the association of cardiovascular morbidity and mortality with baseline glomerular filtration rate (GFR), calculated according to the Cockcroft-Gault and MDRD formulas, with the incidence of major adverse cardiovascular events (MACEs) in a cohort of hypertensive individuals followed for 12 years. METHOD: We performed a prospective study of a random sample of 223 hypertensive patients free of MACEs, who were followed in an urban Primary Care Centre. GFR was estimated using both formulas. MACEs were considered as the onset of ischaemic heart disease, heart failure, heart attacks, peripheral vascular disease or cardiovascular death. Data were analysed using the life-table method and Cox regression modeling. RESULTS: The median follow-up was 10.7 (interquartile range, 6.5-12.1) years. Follow-up was completed in 191 participants (85.7%). The cumulative survival was 64.7% (95% Confidence Interval (CI), 57.9-71.6). The incidence of MACEs during the follow-up period was 3.6 (95% CI, 2.7-4.4) per 100 subject-years. The final multivariable model showed that the most predictive variables of MACEs in the study population were the presence of diabetes mellitus and the estimation of GFR ≥60 ml/min/1.73 m2 by MDRD equation. CONCLUSIONS: There was a relationship between the occurrence of MACEs and an estimated GFR by MDRD above 60 ml/min/1.73 m2 at study entry, inversely to what was expected. GFR estimated by the C-G formula was not associated with cardiovascular risk.
