Pharmacotherapeutic care is now expanding in public mental health institutions. Annual grants are funding the public psychiatric field, hindering access to therapeutic innovation and expensive medications due to long length of stay. On the threshold of the French Healthcare & Social Services Ministry \"Ma Santé 2022\" plan (\"My Health 2022\"), there is a risk of altering the continuum of care because of the complexity of the financing of certain high added value therapies. Despite a desire to adapt the system to meet constantly changing health needs, no actions have been taken to this date in psychiatry, with no funds being allocated for valuable medication, in contrary to follow-up care and rehabilitation structures, to our knowledge. This reinforces the discrepancy with the evolution of research, and further widens the gap in inequalities between health sectors. Optimising the funding of expensive medicines in psychiatry would make it possible to reduce the stranglehold of current allocations. Following the example of recent reforms in the follow-up care and rehabilitation structures, extra funds for high value-added therapies would make it possible to reduce complex medical decisions: from prevention to reintegration, patient care continuity would be vastly guaranteed.

BACKGROUND: In the context of health expenses control, reimbursement of high-cost medicines with a \'minor\' or \'nonexistent\' improvement in actual health benefit evaluated by the Haute Autorité de santé is revised by the decree of March 24, 2016 related to the procedure and terms of registration of high-cost pharmaceutical drugs. This study aims to set up the economic impact of this measure.
METHODS: A six months retrospective study was conducted within a French university hospital from July 1, 2015 to December 31, 2015. For each injectable high-cost anticancer drug prescribed to a patient with cancer, the therapeutic indication, its status in relation to the marketing authorization and the associated improvement in actual health benefit were examined. The total costs of these treatments, the cost per type of indication and, in the case of marketing authorization indications, the cost per improvement in actual health benefit were evaluated considering that all drugs affected by the decree would be struck off.
RESULTS: Over six months, 4416 high-cost injectable anticancer drugs were prescribed for a total cost of 4.2 million euros. The costs of drugs with a minor or nonexistent improvement in actual benefit and which comparator is not onerous amount 557,564 euros.
CONCLUSIONS: The reform of modalities of inscription on the list of onerous drugs represents a significant additional cost for health institutions (1.1 million euros for our hospital) and raises the question of the accessibility to these treatments for cancer patients.
