Objectives: To evaluate the impact of local recommendations on off label use of recombinant activated factor VII.
Type of study: Observational, retrospective.
Material and methods: Recommendations have been diffused by a local working group in 2004, concerning seven groups of indications (traumatology, cardiac, hepatic and various surgeries, obstetrics, neurology and haematology). Conformity to recommendations was studied according to 4 axes: respect of prescribing procedure, indication, posology, and pre ones required with the administration.
Results: There were thirty-one uses from 2004 to 2006. Thirty patients presented a massive haemorrhage (blood products before administration of recombinant activated factor VII expressed in median [min-max]: red blood cell unit=15 [0-37], fresh frozen plasma=11 [0-21]). Gravity score at the admission: SAPSII=55+/-22 (average+/-SD), 87% patients presented haemorrhagic shock. Prescribing procedure was in conformity with recommendations in 45%, indications were correct in 74%, posology in 55%, and 16% of prescriptions were completely conform.
Conclusion: With the tariffing to the activity reform, the reimbursement of off label use of expensive molecules will depend on the respect of the evidence-based medicine. According to this study, the observance of local recommendations was insufficient. Rationalizing prescriptions for practice improvement seemed to be difficult and challenging.
