[Neurosurgical and endovascular treatment of intracranial aneurysms: a cost analysis of two different strategies at the University Hospital of Bordeaux (France)]. / Traitement neurochirurgical et endovasculaire des anévrismes intracrâniens. Approche économique de deux alternatives thérapeutiques sur le CHU de Bordeaux.

BACKGROUND: Rupture of intracranial aneurysms causes major mortality and morbidity. Moreover, treatment of this vascular malformation generates high medical costs. We compared the cost of two different strategies employed at the University of Bordeaux to prevent aneurysms from rebleeding: a classical neurosurgical technique consisting in clipping the neck of the aneurysm and a new less invasive neuroradiological technique based on embolization using platinum coils. METHOD: A micro-cost study was carried out retrospectively from May 1998 to June 2000) comparing data from 44 patients admitted for ruptured intracranial aneurysm: 22 operated patients and 22 patients treated with an endovascular approach. Each operated patient was matched with an embolized patient for clinical status at admission (World Federation of Neurological Surgeons Scale) and complications resulting from cerebral hemorrhage (hydrocephalus, vasospasm, rebleeding). RESULTS AND CONCLUSION: Our results showed the same cost for the same efficiency . Expenditures are however made differently. The endovascular technique allows a shorter hospital stay (8 days less), balancing the high cost of single use medical supplies (coils, microcatheters.). The endovascular technique has many advantages for the patients, but cannot be successful in all types of intracranial aneurysms. Both techniques remain indispensable.

Intravenous and oral antibiotics in respiratory tract infection: an international observational study of hospital practice.

BACKGROUND: Hospitalised patients with respiratory tract infections (RTI) frequently receive intravenous (i.v.) antibiotics followed by a short course of oral treatment. OBJECTIVES: To observe antibiotic use in hospitals in Germany, Spain, France, Italy and the UK and the reasons for choosing the i.v. route and switching to oral treatment. METHODS: Research pharmacists sought the opinions of physicians and senior nurses in the completion of a semi-structured questionnaire on the treatment of RTI with i.v. antibiotics. Questions focussed on antimicrobials of choice, reasons for choosing i.v., reasons for changing to oral administration, and duration of treatment. RESULTS: This study recruited 796 patients with RTI, usually pneumonia. Prescribing patterns varied widely between the five hospitals. Accepted clinical criteria were only commonly cited in Germany, Spain and the UK as reasons for choosing the i.v. route at the beginning of the study. These were more commonly cited at the time of switch, although other criteria such as improved condition, were other significant reasons. The mean duration of i.v. treatment ranged from 4 days in the UK to 10 days in Italy, where most patients received the full course of treatment by the i.v. route. Unlike the other hospitals studied, the few patients in Italy who were switched to another form of treatment were as likely to receive intramuscular as oral administration (13% and 11%, respectively). CONCLUSIONS: The practice of and reasons for prescribing i.v. antibiotics varied in the hospitals studied. Objective clinical criteria were inconsistently cited as reasons for administering i.v. antibiotics and in general these reasons were unrelated to those given for the switch from i.v. to oral administration. In order for guidelines for switching from i.v. to oral antimicrobials to be routinely employed, explicit physiological criteria need to be recorded in a routine fashion. Closer co-operation between pharmacists and physicians may help in developing and implementing guidelines at a local level.
