Abstract

Objective: To study whether the visits of technical health representatives (ITS) mean that new drugs are introduced. Design. Prospective, descriptive study.

Setting: Urban health centre.

Participants: The products presented by 137 ITS from 83 drug laboratories in weekly sessions for a year were studied.

Main measurements: The products presented, the year they were first marketed, intrinsic value (IV), newness and use potential, cost per package and defined daily dose and material handed over were studied.

Results: 472 drug products were introduced. The most common ones belonged to the cardiovascular group (27.3%), digestion and metabolism (14.8%) and anti-infection drugs (13.3%). 65.5% had been on the market for <5 years. 84.3% had a high IV. Only 31 products (6.6%) were new (95% CI, 4.5-9.2). 71% of these supposed no or very slight therapeutic improvement, 25.8% a modest improvement and 3.2% a major improvement. Mean cost was 19.3 euros per package and 2 euros per DDD, with significant differences found (P<.006) on stratifying by date of marketing (more recently marketed products cost more). 61% of the products were presented with additional material (leaflets, monographs, journals), 21.6% with gifts of symbolic value, and 19.9% with samples of the product. There were significant differences (P<.03) between the new drugs and the normal prescriptions issued at the centre. In the new drugs, there were fewer products with high IV and cost per package and per DDD was higher.

Conclusions: The products introduced by the reps do not include any important new drugs. They are presented with abundant back-up and are more expensive than those normally prescribed.

Objetivo: Estudiar si las visitas de los informadores técnicos sanitarios (ITS) suponen la presentación de novedades farmacológicas

Diseño: Estudio descriptivo, prospectivo

Emplazamiento: Centro de salud urbano

Participantes: Se estudiaron los productos presentados por 137 ITS de 83 laboratorios mediante sesiones semanales durante un año

Mediciones principales: Se estudiaron los productos presentados, el año de comercialización, el valor intrínseco (VI), la novedad y el potencial de uso, el coste por envase y dosis diaria definida (DDD) y el material entregado. Dichos productos se compararon con una muestra aleatoria de la prescripción anual del centro

Resultados: Se presentaron 472 productos farmacéuticos. Los más frecuentes fueron de los grupos siguientes: cardiovascular (27,3%), digestivo y metabolismo (14,8%) y antiinfecciosos (13,3%). El 65,5% llevaba comercializado menos de 5 años. El 84,3% tenía un VI elevado. Solamente 31 productos (6,6%) eran novedades (intervalo de confianza [IC] del 95%, 4,5–9,2). De ellos, el 71% supuso una nula o muy pequeña mejora terapéutica, el 25,8% una modesta mejora y el 3,2% una importante mejora. El coste medio fue de 19,3 euros por envase y de 2,0 euros por DDD, con diferencias significativas (p < 0,006) al estratificar por la fecha de comercialización (coste superior en los productos más recientemente comercializados). El 61% de los productos se presentó con material adicional (folletos, monografías, revistas, libros), el 21,6%, con regalos de valor simbólico, y el 19,9%, con muestras del producto. Se observaron diferencias significativas (p < 0,03) respecto a la prescripción habitual del centro: proporción inferior de productos con VI elevado y coste superior por envase y por DDD

Conclusiones: Los productos presentados por los ITS no suponen novedades importantes, se presentan con abundante soporte y son más caros que los prescritos habitualmente
