Our one-year retrospective study evaluated drug use in a population of 136 patients over 60 years old hospitalized in a geriatric ward (moderate--and long-term institutionalization). After having classified the reason for hospitalization, the length of stay and the number of pathologies per patient, the number of prescribed medications was quantified by means of a drug-day unit (D-D). The mean number was 3.36 D-D, which was independent of sex, age and reason for admission. The most frequently prescribed medications treated central nervous system, cardiovascular and metabolic disorders. These results were compared to those of CREDOC 1981 and CREDES 1987. In addition, 14 iatrogenic episodes were identified in this study; aminoglycosides and cardiovascular drugs were responsible for the majority of them, despite the precautions taken in light of the therapeutic indications. The iatrogenesis thus identified was not due to biological abnormalities found in the elderly. In our opinion, this evaluation of drug use is a good predictive element for understanding iatrogenicity on a larger scale and thereby to attempt to avoid it.
