Pharmacosurveillance in hospitalized patients in Italy.: Study design of the 'Gruppo Italiano di Farmacovigilanza Nell'Anziano' (GIFA)

The Italian Group of Pharmacoepidemiology in the Elderly (Gruppo Italiano di Farmacovigilanza nell'Anziano, GIFA) is a collaborative pharmacosurveillance study in hospitalized patients, sponsored by the Italian National Research Council (CNR) and the Italian Society of Gerontology and Geriatrics. It was founded in 1987 with the aim to constitute a multicentre research group to study quality of care and problems related to pharmacological therapy in the elderly. Until now the GIFA study has completed seven periodical surveys and enrolled a total of 28,411 hospitalized patients in 83 clinical centres. The database of the study contains approximately 174,000 in-hospital drug prescriptions, approximately 88,000 discharge diagnoses and a great deal of data on topical geriatric items such as cognitive performance, disability, comorbidity, adverse drug reactions and incontinence. This paper describes the general organization and the methods of the GIFA study and shows in detail the type of data collected. (C) 1999 Academic Press.
