This website session will gradually present HAS pilot projects and seminars dedicated to clinical impact outcome research in different medical themes, including tools for improvement such as guidelines and indicators, implementation projects and results in terms of clinical impact.

• Alzheimer’s disease and iatrogenicity of antipsychotics
• "Full care cycles" HAS Expert Seminar, 15th-16th December 2011

HAS, the national French Authority for Health, as an independent, public and scientific institution, aims to enhance the quality of healthcare at both an individual and collective level in order to insure that all patients and users have equal and permanent access to the most effective, safe and efficient care as possible.

Because of the complexity of health care and interventions the final objective of quality improvements has to be the achievement of improved patient outcomes. These outcomes could be the final ones such as survival or handicap rates, quality of life or morbidity, but could be defined all along the patient pathway or life. These concrete intermediary and final results for the patient define the “clinical impact’ of care on which HAS has devoted outcome research.

So as to improve the quality and safety of healthcare in respect of major healthcare topics requiring complex management, in a comprehensive and participative approach, HAS is implementing pilot programs which include every type of healthcare procedure to achieve improved clinical impact for the patient.

Two fields of health issues are explored by the clinical impact pilot programmes, as models for the combination of medical and quality expertise: cardiovascular diseases with Myocardial infarction and Stroke pathways, from the very 1st symptoms to the 1 year follow up; geriatrics complex clinical situations such as polyprescriptions and prevention of iatrogenicity in the elderly and particularly in Alzheimer disease.
