Résumé
La pharmacothérapie et la thérapie cognitive-comportementale (TCC) sont des traitements de choix pour le Trouble panique avec agoraphobie (TPA) mais demeurent généralement dispendieux. La présente étude vise à comparer les ratios coûts/efficacité d’une TCC pour le TPA versus un traitement combinant la TCC à une pharmacothérapie. Quatre-vingt-quatre participants suivent une TCC combinée ou non avec une médication. Ils sont évalués avant et après le traitement ainsi qu’au suivi d’un an et de deux ans. L’efficacité de la thérapie est calculée à partir d’un « Index de fonctionnement global » pour chaque temps de mesure. Les coûts directs et indirects pour leur part, sont calculés grâce à une « Entrevue sur les coûts de la santé ». Les résultats suggèrent que pour une efficacité équivalente, la TCC seule demeure moins dispendieuse qu’une TCC combinée à une pharmacothérapie. Elle offre donc un meilleur ratio coûts/efficacité. Ce ratio tend même à augmenter avec le temps.
Abstract
Pharmacotherapy and cognitive-behavioral therapy (CBT) are efficient treatments for Panic disorder with agoraphobia (PDA) yet they remain expensive. This study aims to compare the cost/effectiveness ratio of a CBT for PDA versus a combined treatment of CBT and pharmacotherapy. Eighty-four people followed a CBT either alone or combined with medication. They have been evaluated before treatment, immediately after, as well as one and two years later. The therapy efficacy is calculated at each assessment according to a “Global Functioning Index”. Direct and indirect costs are calculated with the “Health Cost Interview”. Results suggest that both treatments are equally effective. However, CBT alone is less expensive than CBT with pharmacotherapy. Thus, it offers a better cost-effectiveness ratio that even increases in the long term.
Resumen
La farmacoterapia y el tratamiento cognitivo comportamental (TCC) son tratamientos electivos para el trastorno de pánico con agorafobia (TPA) pero generalmente son costosos. El presente estudio busca comparar las proporciones costos/eficacia de un TCC para el TPA con un tratamiento que combina el TCC con una farmacoterapia. Ochenta y cuatro participantes siguieron un TCC combinado o no con medicación. Fueron evaluados antes y después del tratamiento así como uno y dos años después. La eficacia de la terapia se calcula a partir de un “Índice de funcionamiento global” para cada tiempo de medida. Los costos directos e indirectos, por su parte, son calculados gracias a una “Entrevista para determinar los costos de la salud”. Los resultados sugieren que para una eficacia equivalente, el TCC sólo es menos costoso que un TCC combinado con la farmacoterapia. Éste ofrece entonces una mejor proporción costos/eficacia. Esta proporción tiende incluso a aumentar con el tiempo.
Resumo
A farmacoterapia e a Terapia Cognitivo-Comportamental (TCC) são bons tratamentos para o Transtorno do Pânico com Agorafobia (TPA), mas são, em geral, dispendiosos. O presente estudo visa comparar as relações de custo e eficácia de uma TCC para o TPA em comparação com um tratamento que associa a TCC a uma farmacoterapia. 84 participantes seguiram uma TCC associada ou não a uma medicação. Eles foram avaliados antes e após o tratamento e também depois de um ano e depois de dois anos. A eficácia da terapia foi calculada a partir de um “índice de funcionamento global” para cada tempo de medida. Os custos diretos e indiretos por outro lado, foram calculados graças a uma “entrevista sobre os custos da saúde”. Os resultados sugerem que, para uma eficácia equivalente, a TCC sozinha continua sendo a menos dispendiosa que uma TCC associada com uma farmacoterapia. Ela oferece, então, uma melhor relação de custo e eficácia. Esta relação tende até a aumentar com o tempo.
