[Estimation of the costs of radiographic and endoscopic examinations in gastroenterology using monographic studies]. / Estimation du coût des examens radiographiques et endoscopiques en gastroentérologie au moyen d'études monographiques.

This study is devoted to the study of rate-setting and cost price of fifteen radiological and endoscopic examinations in gastroenterology as based on monographic studies. In rate-setting the costs are the examinations actually performed in the department. In contrast, the cost price allocated to include only the expenses incurred by each examination and not those related to the time running between them. Both estimations converge when rooms and equipment are used maximally. Our results show that the amounts reimbursed by the Social Security system were always lower than those obtained from monographic studies, except for two radiological examinations for which expenses were adequate. However when cost prices are considered, all reimbursements would have to be increased for endoscopic examinations, but for Radiography, only those of cholangiography, cholecystography and small bowel barium series should be adjusted.
