ABSTRACT
RESUMEN Objetivo. Evaluar la eficacia de un protocolo estandarizado y simplificado basado en los pilares técnicos de la Iniciativa HEARTS para el control de pacientes hipertensos del Programa de Salud Cardiovascular en el primer nivel de atención de salud en Chile. Métodos. Estudio observacional longitudinal (cohorte histórica), en 2 centros de salud familiar del primer nivel de atención en Santiago, que comparó el control de presión arterial en adultos hipertensos logrado con el protocolo estandarizado y simplificado, frente al protocolo habitual, según las guías nacionales. Las innovaciones del protocolo estandarizado incluyeron cambios en la coordinación del equipo de salud, inicio de tratamiento farmacológico inmediatamente después de confirmación diagnóstica, tratamiento farmacológico estandarizado con combinación de al menos 2 o 3 fármacos antihipertensivos en un sólo comprimido, en una toma diaria. Se realizó seguimiento por 1 año para evaluar el porcentaje de adherencia al tratamiento y cumplimiento de metas de control de presión arterial (menor a 140/90 mmHg). Resultados. Se evaluaron 1 490 pacientes: 562 que utilizaron el protocolo estandarizado y simplificado y 928 tratados con el protocolo habitual (centros de salud familiar-1: 650, centros de salud familiar -2: 278). A 1 año de seguimiento, los pacientes del grupo del protocolo estandarizado y simplificado tuvieron mayor proporción de cumplimiento de metas de control de presión arterial (65% versus 37% y 41%, p<0,001) y mayor porcentaje de adherencia al tratamiento en comparación con aquellos con el protocolo habitual (71% versus 18% y 23%, p<0,001). Conclusiones. Los resultados muestran que el protocolo estandarizado y simplificado es más efectivo que el protocolo habitual en el control de hipertensión arterial en pacientes en tratamiento en el primer nivel de atención en Chile. Su implementación a nivel nacional podría contribuir a la disminución de eventos cardiovasculares mayores.
ABSTRACT Objective. To evaluate the effectiveness of a standardized and simplified protocol based on the technical pillars of the HEARTS Initiative for the control of hypertensive patients in the Cardiovascular Health Program at the first level of care in Chile. Methods. Longitudinal observational study (historical cohort) in two family health centers at the first level of care in Santiago. The control of blood pressure in hypertensive adults using a standardized and simplified protocol was compared to the usual protocol based on national guidelines. Innovations in the standardized protocol included changes in how the health team is coordinated, initiation of pharmacological treatment immediately after confirmed diagnosis, standardized pharmacological treatment with a combination of at least two or three antihypertensive drugs taken daily in a single tablet. Follow-up was conducted after one year to assess the percentage of adherence to treatment and achievement of blood pressure control targets (< 140/90 mmHg). Results. A total of 1490 patients were evaluated: 562 who followed the standardized and simplified protocol, and 928 who were treated with the usual protocol (family health centers: 650; family health centers: 278). After one year, patients in the standardized and simplified protocol group had a higher proportion of adherence to blood pressure control targets (65% versus 37% and 41%, p<0.001) and higher adherence to treatment compared to those following the usual protocol (71% versus 18% and 23%, p<0.001). Conclusions. The results show that the standardized and simplified protocol is more effective than the usual protocol in controlling arterial hypertension in patients undergoing treatment at the first level of care in Chile. Its implementation at the national level could contribute to a decrease in major cardiovascular events.
RESUMO Objetivo. Avaliar a eficácia de um protocolo padronizado e simplificado, com base nos pilares técnicos da iniciativa HEARTS, para o controle de pacientes com hipertensão arterial do Programa de Saúde Cardiovascular na atenção primária à saúde do Chile. Métodos. Estudo observacional longitudinal (coorte histórica) em 2 centros de atenção primária de saúde da família em Santiago, que comparou o controle da pressão arterial em adultos com hipertensão, atingido com o protocolo padronizado e simplificado, versus o protocolo habitual, de acordo com as diretrizes nacionais. As inovações do protocolo padronizado incluíram mudanças na coordenação da equipe de saúde, início do tratamento farmacológico imediatamente após a confirmação do diagnóstico e tratamento farmacológico padronizado com associação de pelo menos 2 ou 3 anti-hipertensivos em um único comprimido, tomados uma vez ao dia. O acompanhamento foi realizado por 1 ano para avaliar o percentual de adesão ao tratamento e o cumprimento das metas de controle da pressão arterial (menor que 140/90 mmHg). Resultados. Foram avaliados 1.490 pacientes: 562 que utilizaram o protocolo padronizado e simplificado e 928 que foram tratados com o protocolo habitual (unidade de saúde da família 1: 650, unidade de saúde da família 2: 278). Em 1 ano de seguimento, os pacientes do grupo do protocolo padronizado e simplificado apresentaram maior proporção de cumprimento das metas de controle da pressão arterial (65% versus 37% e 41%, p<0,001) e maior percentual de adesão ao tratamento, em comparação com aqueles que utilizaram o protocolo habitual (71% versus 18% e 23%, p<0,001). Conclusões. Os resultados mostram que o protocolo padronizado e simplificado é mais eficaz que o protocolo habitual no controle da hipertensão arterial em pacientes que estão em tratamento na atenção primária do Chile. Sua implementação no nível nacional poderia contribuir para a redução de eventos cardiovasculares maiores.
ABSTRACT
Background: Type 2 Diabetes Mellitus is not always treated successfully, in part due to the difficulties perceived by the medical community about the use of insulin. Aim: To identify the constraints perceived by primary care physicians (PCPs) in the prescription and use of insulin. Material and Methods: Six PCPs were subjected to a semi-structured interview about self-perceived management difficulties, behaviors and beliefs on the use of insulin among diabetics. According to their responses a questionnaire about the subject was devised and PCPs were invited by e-mail to answer it. Results: There were 88 replies and 48 percent of respondents recognized to have management deficiencies in at least one aspect of insulin prescription. The most common deficiencies were determining the type of insulin and treatment of complications. The perceived difficulties were lack of training (58.0 percent), lack of medical hours (46.6 percent), lack of communication with specialists (46.6 percent), lack of reactive strips for capillary blood glucose determination (43.2 percent) and rotation of doctors (40.9 percent). The most common behaviors towards patients reluctant to use insulin were persuasion (83.0 percent), education and supervisión (63.6 percent) and signature ofan ad-hoc document (38.6 percent). Ninety percent considered that timely use of insulin is more beneficial than its prescription as a last resort and 94.3 percent did not consider that insulin should be prescribed by a specialist. Conclusions: A significant percentage of physicians do not trust their own knowledge about insulin prescription. These professionals should receive training in not only technical aspects of prescribing insulin, but also in the psychological and persuasión strategies. There is willingness among PCPs to prescribe insulin.

A serologic study of Chagas disease was performed in 110 patients submitted to chronic hemodyalisis and blood transfusions. Immunofluorescence antibody testing (IgG and IgM) was positive in 6 out of 62 patients receiving multiple blood transfusions (9.7% ), but negative in all 48 subjects without transfusions. Thus, repeated blood transfusión is a significant risk for T cruzi infection in chronic hemodyalized patients

Se presenta una descripcion breve sobre el gato como huesped completo y definitivo de Toxoplasma gondii y sobre la importancia epidemiologica de los ooquistes esporulados del parasito como fuente de infeccion para toxoplasmosis humana. Un estudio serologico preliminar, practicado mediante reaccion de Sabin y Feldman, en 32 gatos no seleccionados de Santiago, presento resultados positivos (a titulos: 1/16) en 19 casos (59,3%). La demostracion de anticuerpos contra toxoplasma en el 59,3% de los gatos, indica la necesidad de seguir el estudio de la toxoplasmosis en gatos con el fin de precisar la importancia de la transmision del T. gondii a traves del fecalismo en nuestro medio
