Abstract

In a multiclinic use-effectiveness study, 505 parous women were fitted with an Ortho Gyne-T380 Slimline intrauterine device (IUD). Gross cumulative event rates, calculated by the Tietze-Potter life-table method, show the device to have a very low pregnancy rate and a low expulsion rate. The rate of removal following complaints of bleeding and/or pain was high. The incidence of infection was low and more likely to occur among younger users. The older parous women were more likely to have a satisfactory experience of IUD use than younger users. In accordance with current advice, and following a full discussion with the client, long-term use of the device beyond the manufacturer's recommended time period will continue among satisfied users.

Resumé

Le dispositif intra-utérin Slimline Ortho Gyne-T380 a fait l'objet d'une étude sur son efficacité, menée dans plusieurs cliniques, avec la participation de 505 femmes ayant eu des enfants. Les taux cumulés bruts des événements, calculés par la méthode des tables de survie de Tietze-Potter, montrent que, pour ce dispositif, le taux de grossesse est très faible et que celui des expulsions est peu élevé. Le pourcentage des retraits pour cause de saignements et/ou de douleurs était élevé. Les cas d'infection étaient peu nombreux et susceptibles de se produire davantage chez des sujets jeunes. Les femmes plus âgées avaient plus de chances d'être satisfaites du port de ce disporsitif que les plus jeunes. Selon les conseils couramment donnś, et après en avoir pleinement discuté avec l'intéressée, les utilisatrices satisfaites continueron à porter ce dispositif au delà de la durée d'utilisation recommendée par le fabricant.

Resumen

En un estudio multiclínica de uso-eficacia, se colocó und ispositivo intrauterino (DIU) Ortho Gyne-T380 Slimline a 505 mujeres que ya habían tenido hijos. Las proporciones acumulativas de acontecimientos, calculadas según el método de tablas de vida de Tietze-Potter, indican que el dispositivo tiene una proporción muy baja de embarazos y una proporción baja de expulsión fue baja y con mayores probabilidades de ocurrir entre usuarias jóvenes. Hubo mayores probabilidades de que las mujeres de más edad que habían tenido hijos tuvieran una experiencia satisfactoria con el uso del DIU que las usuarias más jóvenes. De conformidad con la actual información, y tras una conversación am plia con la paciente, el uso del dispositivo a largo plazo más allá del período de tiempe recomendado por el fabricante continauará entre las usuarias satisfechas.
