Adverse Drug Reactions Leading to Hospital Admission

This article describes the implementation of a simple method of drug surveillance set up at a hospital emergency ward. From a total of 48678 patients admitted, the medical records of those presenting with one or more of a pre-established list of admission diagnoses (n = 7728; 15.8%) were checked. Of these 554 (1.1%) were diagnosed as experiencing an adverse drug reaction. When the medical record suggested an adverse drug reaction, drugs taken before admission were ascertained by interviewing the patients with a structured questionnaire.
