Objetivos

Estudios recientes demuestran que la inyección intravenosa de somatostatina previa a la práctica de una CPRE se acompaña de una significativa reducción de la tasa de pancreatitis aguda post-CPRE. Ante la falta de datos en nuestro medio, hemos querido estudiar el posible beneficio económico de la administración de somatostatina, obtenido a través de la disminución de los costes debidos a las pancreatitis agudas post-CPRE.

Material y Método

Estudio teórico de los costes directos de la pancreatitis aguda post-CPRE, mediante el método del “árbol de decisiones” de Markov. Se comparan los costes del grupo pretratado con administración intravenosa de 3 mg de somatostatina con respecto al grupo control. Se aceptan unas tasas de pancreatitis post-CPRE del 10% en el grupo control y del 3% en grupo con somatostatina. Los costes de los distintos tipos de pancreatitis, sin y con complicaciones y con actuación quirúrgica, se han basado en los pesos por GDR aplicados por el Ministerio de Sanidad y en el Contrato-programa del Servicio Navarro de Salud para 1999. Se ha efectuado un análisis de sensibilidad para precisar a partir de qué tasa de pancreatitis post-CPRE se obtendría un beneficio económico en el grupo pretratado con somatostatina.

Resultados

El coste medio teórico por exploración fue de 121.640 pesetas para el grupo control y de 105.539 pesetas para los tratados con somatostatina, con un ahorro por caso del 13,26% (16.101 pesetas). El análisis de sensibilidad demuestra que con la premedicación se obtiene un beneficio económico a partir de tasas de pancreatitis del 4,2% en el grupo control.

Conclusiones

Con independencia del beneficio clínico que significa la reducción de pancreatitis post-CPRE, la administración de somatostatina supone un ahorro de 16.101 pesetas por paciente. Aceptando que la tasa de pancreatitis en el grupo tratado se reduce de manera proporcional, el análisis de sensibilidad pone de manifiesto que con la premedicación se obtiene un beneficio económico a partir de tasas de pancreatitis del 4,2% en el grupo control.

Objectives

Recent studies show that intravenous injection of somatostatin before endoscopic retrograde cholangiopancreatography (ERCP) is associated with a significant reduction in the rate of post-ERCP acute pancreatitis. The lack of data in our environment led us to study the possible economic benefits of somatostatin administration, obtained through the reduction of costs due to post-ERCP acute pancreatitis.

Material And Method

Theoretical study of the direct costs of post-ERCP acute pancreatitis using Markov's tree decisions. The costs of the group pre-treated with intravenous administration of 3 mg of somatostatin were compared with those of the control group. Post-ERCP rates of pancreatitis of 10% were accepted in the control group and rates of 3% were accepted in the somatostatin group. The costs of the different types of pancreatitis were as follows: costs with and without complications and with surgical intervention were based on the diagnosis related group-weights applied by the Ministry of Health in the Contract-program of the Health Service of Navarre for 1999. A sensitivity analysis was carried out to determine the rate of post-ERCP pancreatitis from which an economic benefit would be obtained in the group pre-treated with somatostatin.

Results

Mean theoretical cost per procedure was 121,640 pesetas for the control group and 105,539 for the group pretreated with somatostatin. Saving per patient was 13.26% (16,101 pesetas). The sensitivity analysis revealed that in the control group premedication produced an economic benefit starting from a pancreatitis rate of 4.2%.

Conclusions

Independently of the clinical benefit signifying the reduction of post-ERCP pancreatitis, somatostatin administration led to a saving of 16,101 pesetas per patient. Accepting that the pancreatitis rate in the treated group was proportionately reduced, the sensitivity analysis showed that premedication produced an economic benefit starting from a pancreatitis rate of 4.2% in the control group.
