Statins: new American guidelines for prevention of cardiovascular disease

Just change the values or target population and more people will receive more medication, is it a real  major step in the prevention of cardiovascular disease ?  Not for me, what do you think after read the new guidelines ? Are real evidences for the use statins also in primary prevention ? One billons of persons are treated today, all over the world, with this kind of drugs, and the first blockbuster drugs is Atorvastatin.........what about the evidences, and the hundreds of articles against that ? Think for yourself......

Paul M Ridker aEmail Address, Nancy R Cook a

Guidelines released on Nov 13, 2013, by the American Heart Association (AHA) and the American College of Cardiology (ACC) for the management of cholesterol are a major step in the right direction. 1 These new guidelines emphasise prevention of stroke as well as heart disease, focus appropriately on statin therapy rather than alternative unproven therapeutic agents, and recognise that more intensive treatment is superior to less intensive treatment for many patients........full text.

Guias de HTA Arterial 2011 - NICE

Blood circulation: Red = oxygenated Blue = deo...
En el diagnóstico, encontramos algunos de los cambios más importantes de la guía. Según Bryan Williams que ha sido el coordinador de esta edición, la cuarta parte de los pacientes entre 18-40 años están mal diagnosticados, debido al llamado efecto de la bata blanca. Para superar esta situación la guía propone reglas más estrictas a la hora de realizar el diagnóstico y su confirmación mediante la realización de un MAPA durante 24 horas. Más de un médico de familia se llevará las manos la cabeza en este párrafo. Pero como dicen los autores, esta medida está pensada para implantarse gradualmentey evitar exponer a falsos hipertensos a los riesgos reales de los tratamientos.
Sin menoscabo de la modificación de los hábitos de vida (tabaquismo, obesidad, sedentarismo…) base de la prevención cardiovascular, la guía propone el tratamiento farmacológico en aquéllas personas con una presión ≥160/100 mm Hg (>150/95 mm Hg en las medidas ambulatorias) o >140/90 mm Hg (>135/85 mm Hg en las determinaciones ambulatorias) y, además: afectación de órganos diana, enfermedad cardiovascular establecida, enfermedad renal, diabetes o un riesgo cardiovascular a 10 años ≥20%.
Las cifras objetivo son <140/90 mm Hg en los pacientes menores de 80 años, <150/90 mm Hg en los mayores de 80 y 135/85 mm Hg en aquéllos con discrepancias de más de 20/10 mm Hg entre las distintas mediciones.
En cuanto a la farmacoterapia, la guía da recomendaciones específicas para grupos de pacientes especiales, como mujeres embarazadas y en período de lactancia, diabéticos, pacientes jóvenes o con insuficiencia renal crónica. De forma muy general, se propone un IECAcomo agente de primera línea en pacientes menores de 55 años (o un ARA-II de bajo coste, ya que los genéricos están igualando los precios en el mercado británico). Los ARA-II son alternativa a aquéllos, en caso de intolerancia. Y no se recomienda la asociación IECA/ARA-II para tratar la HTA. En pacientes >55 años o de raza negra de origen africano o caribeño, se recomienda comenzar por un antagonista del calcio. En caso de intolerancia o contraindicación (por ejemplo, presencia de edemas) se debe administrar un diurético tiazídico. Es importante reseñar que la guía señala como tiazidas de elección a clortalidona (12,5-25 mg/día ¿para cuándo, Sres de la Industria, una presentación de 25 mg en España? ¿porqué, Sres del Ministerio, no tiene clortalidona un precio acorde a su utilidad terapéutica?) o indapamida (2,5 mg/día) antes que bendroflumetiazida o hidroclorotiazida. Y que no modifica sus recomendaciones respecto a los betabloqueantes, que quedan como fármacos de segunda línea.

Osteoporosis: Las guías de la discordia

Las guías de la discordia
Maria Valerio. El Mundo (España) 12/11/2010
http://tinyurl.com/Mac-guia-osteo




Un documento de consenso avalado por el Ministerio de Sanidad y Consumo y la Generalitat de Cataluña sobre el tratamiento de la osteoporosis ha desatado la polémica en la Red. Algunos de los autores que aparecen como revisores del texto han mostrado su descontento con la versión final y muchos especialistas critican el 'abuso' de los fármacos que promueve.


El doctor Rafael Bravo, especialista en Atención Primaria, fue el primero en soltar la liebre desde su blog al criticar la "dudosa calidad científica" de la llamada Guía de Práctica Clínica sobre Osteoporosis y Prevención de Fracturas por Fragilidad .


A su juicio, el manual apuesta por tratar preventivamente a mujeres postmenopáusicas, sin factores de riesgo, con el objetivo de prevenir supuestamente la aparición de fracturas y empleando unos fármacos (como los bifosfonatos o el raloxifeno) no exentos de riesgo. "Erróneamente se iguala menopausia, osteoporosis y tratamiento farmacológico", explica este experto a ELMUNDO.es.
La osteoporosis es una pérdida de la densidad ósea relacionada con la caída de estrógenos que sufren las mujeres en la menopausia. Como recogen los Institutos Nacionales de Salud de EEUU, el tratamiento está reservado para los casos ya diagnosticados (por medio de un estudio que mide la densidad del hueso) o bien para mujeres con osteopenia (una fase previa a la osteoporosis en la que los huesos están debilitados), pero que ya han sufrido una fractura.


Descontento
Bastó una entrada en su blog, para que algunos de los especialistas que presuntamente habían revisado el documento de 'consenso' manifestaran su sorpresa y su disconformidad con la versión final. Es el caso de Cecilia Calvo, del servicio balear de salud y miembro de la Sociedad Española de Farmacia Hospitalaria. "En mayo de 2009 enviamos los comentarios a un primer borrador del texto y desde entonces no hemos vuelto a saber nada más", se queja. "Hasta que hemos visto nuestro nombre en la publicación final, sin tener en cuenta nuestras consideraciones".
Oriol Solá-Morales, director de Evaluación de la Agència d'Informació, Avaluació i Qualitat en Salut (AIAQS) de Cataluña, el organismo encargado de elaborar la guía a petición del Ministerio, tiene su propia versión de los hechos. "Sabíamos que la osteoporosis es un terreno pantanoso y todo este ruido transmite la idea de que hacía falta una guía; aunque seguramente ésta sea mejorable", admite.
A su juicio, toda esta polémica enfrenta a las dos "posturas" que existen en torno a la osteoporosis "sobre si el tratamiento previene o no las facturas".
De los 15 revisores a quienes se les envió el texto, un 25% de ellos lo devolvió con "cambios mayores" lo que provocó que se incluyeran algunas modificaciones en la versión definitiva que se ha publicado, "pero no es posible incorporar todas las sugerencias porque si no tendríamos que iniciar otra vez el proceso de validación de la evidencia".
Solá-Morales también despeja cualquier duda sobre el papel que haya podido tener la industria farmacéutica en su elaboración: "No conoció el documento hasta que éste se publicó". La agencia ha emitido una nota en la que confirma que 22 de los 25 revisores han aceptado finalmente constar en la versión final de la guía.
Cecilia Calvo recuerda que los fármacos para prevenir las fracturas son más útiles en las mujeres de mayor riesgo, "aunque la guía es muy laxa en este sentido y menciona cualquier medicamento que haya demostrado cualquier cosa, sin tener en cuenta el balance riesgo-beneficios y sin analizar el impacto económico que puede tener su uso en el sistema nacional de salud". A su juicio, con esta guía, el ministerio avala la medicalización de la menopausia, "creando la sensación de que todo el mundo tiene que tratarse".

Guia Clinica: Gastritis Cronica

Helicobacter pylori bacteriaImage via Wikipedia
¿Qué es el Helicobacter Pylori (HP)?
Es un bacilo gram negativo cuya infección se adquiere habitualmente en la infancia y que puede causar gastritis crónica y ulcera péptica 1. También parece ser un factor de riesgo de cáncer gástrico y puede asociarse a linfoma MALT 2. Aunque pequeña, existe una relación entre la infección por HP y la dispepsia no ulcerosa 3.La prevalencia es alta aunque variable, 30-80% de la población adulta está infectada 4. La erradicación del HP cura la úlcera y las reinfecciones son extremadamente raras 5,6.
¿Cuándo está indicado hacer un test para H. Pylori? 3,6,7
Está indicado hacer un test para HP a:
1. Pacientes con enfermedad ulcerosa activa
2. Pacientes sintomáticos con historia documentada de ulcus sin tratamiento erradicador previo. En este grupo de pacientes es tal alta la asociación que puede ser más eficiente tratar sin realizar previamente test alguno
3. Reaparición de los síntomas en un paciente tratado
4. Pacientes con síndrome ulceroso
5. Individuos tratados para confirmar su curación en caso de que: exista úlcera asociada, antecedentes de ulcus y tratamiento antisecretor crónico y persistencia de síntomas dispépticos.
No está indicado hacer el test a:
1. Individuos asintomáticos con historia previa de úlcera
2. Individuos consumidores crónicos de antiácidos por reflujo gastroesofágico.
3. Para confirmar la curación de forma rutinaria
La erradicación del HP se asocia a una mejoría de síntomas de dispepsia, sin embargo no está claro que esté indicado hacer el test a todos los individuos con dispepsia. Parecen necesarios más estudios valorando la relación coste-beneficio en atención primaria 2.
En pacientes con síndrome ulceroso y especialmente en nuestro sistema (con tiempos de espera para pruebas prolongado) una opción razonable y eficiente es la "test and treat". Un paciente con síndrome ulceroso y test HP positivo puede tratarse con terapia de erradicación sin la solicitud de una endoscopia ni una prueba de contraste en individuos menores de 50 años y sin síntomas de alarma8-10.
Si se plantea realizar una gastroscopia el diagnóstico se realizará por biopsia y test rápido de la ureasa. Si no se considera indicada la gastroscopia puede usarse el test de urea en el aliento o la detección de antígeno bacteriano en heces. Este último es más económico y tiene una alta sensibilidad y especificidad. Para evitar falsos negativos el paciente no debe haber tomado antibióticos en las 4 semanas previas ni medicación antisecretora o bismuto en las 2 anteriores 7.
En comunidades urbanas, con prevalencia de infección alta, puede ser útil un test serológico para la detección de anticuerpos IgG para HP (ELISA). Es económico y en esas comunidades puede tener un valor predictivo positivo aceptable. Los anticuerpos disminuyen de forma muy variable e impredecible a lo largo del tiempo por lo que no sirve para confirmar la curación 11.
El test de elección para la confirmación de la erradicación es el test de urea en el aliento, que debe realizarse al menos 4 semanas después de finalizado el tratamiento erradicador 7.
Puntos clave
La erradicación del HP cura la úlcera y las reinfecciones son extremadamente raras >>>
El test diagnóstico de elección si se precisa gastroscopia es la biopsia y test rápido de la ureasa. Sin gastroscopia: test de urea en el aliento o la detección de antígeno bacteriano en heces. En comunidades con prevalencia alta puede usarse el test serológico para la detección de anticuerpos IgG (ELISA).
Para confirmar la erradicación debe usarse el test de urea en el aliento. >>>
Un paciente con síndrome ulceroso y test HP positivo puede tratarse con terapia de erradicación sin la solicitud de una endoscopia ni una prueba de contraste en individuos menores de 50 años y sin síntomas de alarma >>>
Las recidivas son generalmente un problema de resistencia antibiótica que debe tenerse muy en cuenta a la hora de diseñar el tratamiento >>>
La pauta de 7 días con Omeprazol: 20 mgrs/12 horas+ Amoxicilina: 1 gr/ 12 horas+ Claritromicina: 500 mgrs/ 12 horas es la más aceptada como primera elección >>>
Arriba
Sensibilidad y especificidad de los distintos test diagnósticos
Test Sensibilidad Especificidad Coste
Biopsia 99 99 Alto
Serología 92 85 Bajo
Antígeno en heces 92 96 Medio
Urea en aliento 98 99 Alto
¿Cómo tratar los pacientes con HP? 5, 7, 12-15
La triple terapia (un inhibidor de la bomba de protones- IBP- y 2 antibióticos) durante 1 semana es el tratamiento de elección. Es más eficaz que la doble terapia y tanto como la cuádruple, menos aceptable. Una semana es casi tan efectiva como 2, con menor coste y menos efectos adversos (mejor relación coste-efectividad). La erradicación se produce en el 82-84% de los casos16. En caso de erradicación, las reinfecciones suponen menos del 1% anual.
Todos los médicos debemos conocer un segundo régimen terapéutico para usar en caso de fracaso del primero. Las recidivas son generalmente un problema de resistencia antibiótica que debe tenerse en cuenta a la hora de diseñar el tratamiento y que ocurre de forma usual después de un fracaso terapéutico. El H. Pylori es resistente a Metronidazol en 15-66% y en 8-30% a Claritromicina. No existe resistencia a la Amoxicilina y es baja o inexistente a las Tetraciclinas 17.
En caso de haber usado recientemente para cualquier indicación Claritromicina debe usarse un tratamiento antibiótico alternativo. El fracaso de un régimen terapéutico que contenga Claritromicina está generalmente en relación con resistencia a este antibiótico.
La diferencia entre distintos IBP es mínima en cuanto a seguridad y eficacia. En caso de insuficiencia hepática la dosis de Omeprazol no debe exceder de 20 mg/ día. Omeprazol interfiere con cumarínicos y fenitoina.
Prestar atención a: incumplimiento terapéutico, enfermedad maligna de base, test HP negativos por tratamientos recientes (antibiótico o IBP), uso no declarado de AAS o AINE, enfermedad de Crohn y síndrome de Zoellinger-Ellison.
(*) Omeprazol o cualquier otro IBP

Los medicos europeos infravaloran la microalbuminuria

A pesar de que las guías de hipertensión de la Sociedad Europea de Hipertensión (ESH, según sus siglas en inglés) y la Sociedad Europea de Cardiología señalan la microalbuminuria (MAU) como un marcador pronóstico para el desarrollo de enfermedad vascular y un marcador temprano para el daño orgánico, en la práctica clínica europea, la MAU se infravalora como factor de riesgo y herramienta diagnóstica, en especial en relación al riesgo cardiovascular. Así lo apuntó Hermann Haller, director del Departamento de Nefrología e Hipertensión de la Escuela Médica de Hannover, en el marco del encuentro anual de la ESH celebrado en Milán.

Haller presentó junto a Giuseppe Mancia, catedrático de Medicina Clínica de la Universidad de Milán-Bicocca, los resultados de una evaluación médica apoyada por la ESH que dibuja el panorama europeo en el manejo de la MAU. El informe, realizado en mayo, recoge las valoraciones de 1.700 facultativos (800 médicos de atención primaria, 450 cardiólogos y 450 diabetólogos) de Francia, Alemania, Italia, España y Reino Unido.

Según este estudio, más del 90 por ciento de los médicos conocen la importancia de la MAU como predictor del riesgo en pacientes con diabetes e hipertensión, y casi todos ellos lo ligan al daño renal. Pero sólo el 22 por ciento de los médicos de primaria, un 32 por ciento de los cardiólogos y un 38 por ciento de los diabetólogos lo contemplan como un indicador del riesgo de enfermedad cardiaca o infarto de miocardio. Las cifras bajan más aún a la hora de relacionar la MAU con el infarto y las patologías cerebrovasculares, nexo que conocen el 8 por ciento de los médicos de primaria, un 10 por ciento de los cardiólogos y un 15 por ciento de los especialistas en diabetes.

Fácil y asequible

Aunque los médicos europeos son conscientes de este indicador, el objetivo ahora es incrementar la alerta de la MAU como predictor del riesgo cardiovascular y herramienta diagnóstica para la detección temprana del daño orgánico. "El diagnóstico es fácil y asequible y debería incorporarse en la práctica clínica en la línea de otros análisis rutinarios como el colesterol", aseguró Haller. De hecho, puede ser medida a través de un test de orina (no es preciso de 24 horas), que debería repetirse entre dos y tres veces para confirmar si el nivel de albumina sobrepasa los 30 mg.

Sin embargo, este estudio refleja que los médicos de primaria apenas realizan este test al 25 por ciento de sus pacientes, los cardiólogos al 37 por ciento, y los especialistas en diabetes al 22 por ciento de sus pacientes normotensos y al 42 por ciento de los hipertensos. Y lo que es más, el 10 por ciento de los médicos entrevistados no estaba al tanto de que la microalbuminuria pudiera ser medida por un test de orina.

"En la práctica clínica, la reducción del MAU debería ser una meta del tratamiento, además de lograr disminuir la presión. El impacto en esta variable debe ser considerado cuando se seleccione un fármaco para reducir la tensión, ya que debería proporcionar una reducción del riesgo cardiovascular más completa", apuntó Haller. Por otra parte, la reducción de la presión sanguínea se considera la estrategia más importante para reducir la MAU.

La presencia de MAU refleja ampliamente daños en el sistema renal y vascular e indica un aumento significativo del riesgo de ambas patologías, apunta Luis Miguel Ruilope, jefe de la Unidad de Hipertensión del Hospital 12 de Octubre. El especialista asegura que su prevalencia es alta: un estudio en Países Bajos reportó una prevalencia del 7,2 por ciento en la población general, que sube hasta un 16 por ciento en pacientes diabéticos. Otro estudio en más de 32.00 pacientes con diabetes tipo dos sin proteinuria previa o enfermedad renal la sitúa en un 39 por ciento.

Estudio Roadmap

A finales de año se esperan los primeros resultados del estudio Roadmap, el primer ensayo clínico a gran escala que incluye más de 4.400 pacientes para evaluar si olmesartan medoxomil previene la aparición de MAU en pacientes con diabetes tipo dos y al menos uno de los factores de riesgo cardiovascular, en comparación con otros abordajes terapéuticos que excluyan IECA o ARAII. Además, se evaluará si este tratamiento tiene un efecto positivo en la morbilidad y mortalidad cardiovascular y renal.


La actualización de las guías europeas saldrá en octubre


A finales de año la Sociedad Europea de Hipertensión tiene previsto una actualización de las guías de 2007 para el tratamiento de la presión sanguínea. Giuseppe Mancia, presidente del comité organizador del encuentro, anunció su publicación en octubre en el Journal of Hypertension y avanzó algunas novedades. Una de las más importantes será la recomendación de un umbral menor de referencia, entre los 120 mm Hg para la presión sistólica y 70 mm Hg para la diastólica. El presidente del comité organizador del congreso apuntó que por debajo de esta cantidad podría ser peligroso reducir la presión en individuos de alto riesgo, en alusión a la llamada curva J. Otra importante novedad es la apuesta por la terapia a medida, que tenga en cuenta las circunstancias de cada paciente, por encima de aconsejar el uso de antihipertensivos concretos en cada fase de la patología. Un mes antes verán la luz las primeras guías europeas para el control de la hipertensión arterial en niños y adolescentes, que recogen, como un aspecto clave, las indicaciones para la investigación en el futuro, ya que hasta la fecha no existen datos de referencia en niños y adolescentes europeos y se extrapolan los estudios norteamericanos.

Quien tiene tiempo para Medicina Familiar?

Interesante articulo en el que se comenta sobre el exceso de guias de practicas clinicas y la cantidad de horas que llevaria llevar adelante las practicas preventivas que se proponen. Al menos en America del Norte, esto implicaria unas 10,5 horas por dia, cuando el promedio de horas laborables por estos medicos es de casi 8 horas.

Recently a number of articles in the medical literature have discussed the many dissatisfactions of primary care physicians, including family physicians.

Bodenheimer1 has clearly documented the growing pressures on primary care physicians in the United States. Patients are dissatisfied as they experience longer wait times and perceive the quality of care they receive to be inadequate. Physicians are dissatisfied because they feel they are paid for volume, not quality; they earn half the income of specialists and the gap is widening; and they find that the workload is becoming impossible to sustain. The situation is similar in Canadian primary care.

Time pressures

The first published evidence examining family physician workload appeared in 2003. Yarnall et al2 used published and estimated times per service to determine the physician time required to provide all of the services recommended by the US Preventive Services Task Force, at the recommended frequency, to a patient panel of 2500 with an age and sex distribution similar to that of the US population. They found that to fully satisfy the US Preventive Services Task Force recommendations, a physician would have to spend 1773 hours per year, or 7.4 hours per working day, providing preventive services.

Recently, using similar methods, Østbye et al3 applied guideline recommendations for 10 common chronic diseases to a panel of 2500 primary care patients (with an age and sex distribution and chronic disease prevalence similar to those of the general population) and estimated the minimum physician time required to deliver high-quality care for these conditions. The result was compared with time available for patient care for the average primary care physician. They found that 823 hours per year, or 3.5 hours a day, were required to provide care for the 10 most common chronic diseases, provided the diseases were stable and in good control. They recalculated this estimate based on increased time requirements for uncontrolled disease. The estimated time required increased by a factor of 3. Applying this factor to all 10 diseases, time demands increased to 2484 hours per year or 10.6 hours a day. The authors concluded that meeting current practice guidelines for only 10 chronic illnesses requires more time than primary care physicians have available for patient care overall.

When we combine the results of these 2 studies, the average American family physician will spend between 10.9 and 18 hours per day delivering preventive and chronic illness care. Such estimates fail to account for time spent in the delivery of acute care for common conditions, such as upper respiratory tract infections and urinary tract infections, that make up much of a typical day. They also fail to account for time spent outside the examination room answering telephone calls, filling out forms, making referrals, and so on, which takes up a substantial part of the day.4,5

The situation begs some obvious questions. How did expectations for family physicians outstrip the number of hours in the day? Since even the most conscientious family physician is not working 24 hours a day,6 how do family physicians cope with such expectations and demands on their time? Finally, how can expectations of family physicians be made more realistic without compromising the quality of patient care?

Guideline explosion

Several factors have contributed to the time crunch for family physicians, but I believe one factor in particular has had an enormous effect—the explosion of clinical practice guidelines (CPGs) over the past decade. Clinical practice guidelines emerged in the 1970s in most of the industrialized world, beginning with the Canadian Task Force on the Periodic Health Examination in Canada and the US Preventive Services Task Force in the United States. The task forces had an admirable purpose and necessary goals: to evaluate the scientific evidence behind preventive care and to make evidence-based recommendations for practice. These task forces established clear evidence hierarchies and a clear process for the evaluation and the dissemination of clinical evidence. Their recommendations continue to guide primary preventive care today.

Since that time there has been an explosion of CPGs aimed at family physicians. There are more than 2000 guidelines available from the website of the National Guidelines Clearinghouse (www.guideline.gov) in the United States (although not all of them are relevant to family physicians). At last count there were 124 CPGs posted on the website (http://gacguidelines.ca) of the Ontario-based Guidelines Advisory Committee (GAC), an organization dedicated to the evaluation and dissemination of guidelines relevant to family physicians; the GAC’s mission is "to promote better health for the people of Ontario by encouraging physicians and other practitioners to use evidence-based clinical practice guidelines and clinical practices based on best available evidence. In particular, to increase awareness and use of best available evidence, [they] identify, evaluate, endorse and summarize guidelines for use in Ontario."

While the GAC evaluates and rates CPGs according to criteria for quality, there are many problems with CPGs, including many of those that the GAC has favourably evaluated. First, there is strong evidence that guidelines are not developed according to stringent criteria. Shaneyfelt has demonstrated that "Guidelines published in the peer-reviewed medical literature during the past decade do not adhere well to established methodological standards. While all areas of guideline development need improvement, greatest improvement is needed in the identification, evaluation, and synthesis of the scientific evidence."7 Second, guidelines follow the clinical research paradigm and are often developed with only one condition or disease in mind. Patients seen by family physicians usually present with several chronic and interacting conditions, making the application of guideline recommendations more difficult.8 Third, guidelines often do not take into account patient preferences for care, something that family physicians are explicitly trained to do. Fourth, even high-quality guidelines fall short in the way they are disseminated to family physicians. Guidelines are usually passively distributed by mail and in paper form. Although there are increasing exceptions, they also tend to be long, detailed, and do not provide specific clinically useful summaries for busy doctors.9

Improving guidelines

Is there a way to improve CPGs and to reduce the enormous time pressures that burgeoning guidelines place on family physicians? I believe that the answer is yes, but several changes in current practice and in the way that guidelines are developed and disseminated are necessary.

Guidelines need to be "done" differently. Guideline panels typically consist of large numbers of specialist content experts with 2 or 3 family physicians included. Having sat on a guideline panel in the past,10 I can reflect that much of the discussion over 2 days was about research evidence to support the recommendations. While this discussion is critically important, very little time was spent on the equally important issue of dissemination (or knowledge translation). This is a world turned upside down. I propose that guideline panels of the future have much greater representation from family physicians working in different settings, with a small number of content experts to advise them on content. In that way, perhaps, greater attention will be paid to how family physicians can use the guidelines in their practices.

Greater emphasis needs to be placed on applying guidelines to the type of patients seen in family practice settings—the elderly and those with multiple chronic conditions. Furthermore, greater attention needs to be placed on the evidence for the effectiveness of interventions in guidelines. Family physicians are swamped with maneuvers supported only by expert opinion.

This has been said and written many times before, but more attention needs to be paid to the effective dissemination and implementation of good guidelines. Stronger input from family physicians is crucial if dissemination is to be successful.

As family physicians move toward working in family health teams or groups that incorporate and integrate other health care professionals, greater attention needs to be paid to the role of other providers in the delivery of acute, chronic, and preventive care. Clearly, if family physicians are to continue to provide high-quality care and incorporate guideline recommendations into their practices, they will need to share this work with other professionals. Many preventive care maneuvers can be performed, for example, by nurse practitioners integrated into family health teams. Similarly, nurse practitioners can effectively provide care for some chronic conditions, allowing family physicians to focus on acute care or on patients with chronic illnesses that are unstable.

Family physicians are under increasing time pressures to provide both preventive and chronic illness care. The growth in CPGs for both preventive and chronic care and the expectation that they will be closely followed by family physicians has contributed substantially to the time pressures. Improvements in the quality and in the dissemination of guidelines and the integration of other health care providers, such as nurse practitioners, into family health teams could help ease time pressures on family physicians and improve the quality of their work lives.

Who has time for family medicine?

Recently a number of articles in the medical literature have discussed the many dissatisfactions of primary care physicians, including family physicians.

Bodenheimer1 has clearly documented the growing pressures on primary care physicians in the United States. Patients are dissatisfied as they experience longer wait times and perceive the quality of care they receive to be inadequate. Physicians are dissatisfied because they feel they are paid for volume, not quality; they earn half the income of specialists and the gap is widening; and they find that the workload is becoming impossible to sustain. The situation is similar in Canadian primary care.

Time pressures

The first published evidence examining family physician workload appeared in 2003. Yarnall et al2 used published and estimated times per service to determine the physician time required to provide all of the services recommended by the US Preventive Services Task Force, at the recommended frequency, to a patient panel of 2500 with an age and sex distribution similar to that of the US population. They found that to fully satisfy the US Preventive Services Task Force recommendations, a physician would have to spend 1773 hours per year, or 7.4 hours per working day, providing preventive services.

Recently, using similar methods, Østbye et al3 applied guideline recommendations for 10 common chronic diseases to a panel of 2500 primary care patients (with an age and sex distribution and chronic disease prevalence similar to those of the general population) and estimated the minimum physician time required to deliver high-quality care for these conditions. The result was compared with time available for patient care for the average primary care physician. They found that 823 hours per year, or 3.5 hours a day, were required to provide care for the 10 most common chronic diseases, provided the diseases were stable and in good control. They recalculated this estimate based on increased time requirements for uncontrolled disease. The estimated time required increased by a factor of 3. Applying this factor to all 10 diseases, time demands increased to 2484 hours per year or 10.6 hours a day. The authors concluded that meeting current practice guidelines for only 10 chronic illnesses requires more time than primary care physicians have available for patient care overall.

When we combine the results of these 2 studies, the average American family physician will spend between 10.9 and 18 hours per day delivering preventive and chronic illness care. Such estimates fail to account for time spent in the delivery of acute care for common conditions, such as upper respiratory tract infections and urinary tract infections, that make up much of a typical day. They also fail to account for time spent outside the examination room answering telephone calls, filling out forms, making referrals, and so on, which takes up a substantial part of the day.4,5

The situation begs some obvious questions. How did expectations for family physicians outstrip the number of hours in the day? Since even the most conscientious family physician is not working 24 hours a day,6 how do family physicians cope with such expectations and demands on their time? Finally, how can expectations of family physicians be made more realistic without compromising the quality of patient care?

Guideline explosion

Several factors have contributed to the time crunch for family physicians, but I believe one factor in particular has had an enormous effect—the explosion of clinical practice guidelines (CPGs) over the past decade. Clinical practice guidelines emerged in the 1970s in most of the industrialized world, beginning with the Canadian Task Force on the Periodic Health Examination in Canada and the US Preventive Services Task Force in the United States. The task forces had an admirable purpose and necessary goals: to evaluate the scientific evidence behind preventive care and to make evidence-based recommendations for practice. These task forces established clear evidence hierarchies and a clear process for the evaluation and the dissemination of clinical evidence. Their recommendations continue to guide primary preventive care today.

Since that time there has been an explosion of CPGs aimed at family physicians. There are more than 2000 guidelines available from the website of the National Guidelines Clearinghouse (www.guideline.gov) in the United States (although not all of them are relevant to family physicians). At last count there were 124 CPGs posted on the website (http://gacguidelines.ca) of the Ontario-based Guidelines Advisory Committee (GAC), an organization dedicated to the evaluation and dissemination of guidelines relevant to family physicians; the GAC’s mission is "to promote better health for the people of Ontario by encouraging physicians and other practitioners to use evidence-based clinical practice guidelines and clinical practices based on best available evidence. In particular, to increase awareness and use of best available evidence, [they] identify, evaluate, endorse and summarize guidelines for use in Ontario."

While the GAC evaluates and rates CPGs according to criteria for quality, there are many problems with CPGs, including many of those that the GAC has favourably evaluated. First, there is strong evidence that guidelines are not developed according to stringent criteria. Shaneyfelt has demonstrated that "Guidelines published in the peer-reviewed medical literature during the past decade do not adhere well to established methodological standards. While all areas of guideline development need improvement, greatest improvement is needed in the identification, evaluation, and synthesis of the scientific evidence."7 Second, guidelines follow the clinical research paradigm and are often developed with only one condition or disease in mind. Patients seen by family physicians usually present with several chronic and interacting conditions, making the application of guideline recommendations more difficult.8 Third, guidelines often do not take into account patient preferences for care, something that family physicians are explicitly trained to do.
