[Prospective study on admissions for iatrogenic adverse effects in the emergency service of hospital university center in Poitiers]. / Enquête prospective sur les admissions pour iatrogénie médicamenteuse dans le service d'accueil des urgences du centre hospitalier universitaire de Poitiers.

Hospital admissions resulting from an adverse drug reaction have been studied in the emergency unit of the university hospital in Poitiers during a 27-day period. This prospective study consisted in documenting all observations considered as an ADR by the medical practitioner in charge of the patient. There were 1235 hospital admissions to the emergency unit during the study period. Thirty-one (2.5 per cent) of admissions were considered to be drug-related. Women were more often affected than men. Patients with ADR were classified taking into account the type of pathology and the drug responsible for the effect. Dermatological and gastrointestinal reactions were predominant. Antibiotic and analgesic drugs were the most common drug groups implicated in causing an ADR.
