A 6-month prospective survey of cutaneous drug reactions in a hospital setting

Abstract

This study finds a lower incidence than other studies that reported an incidence of 2% of cutaneous drug reactions in hospitalized patients, but only allergic adverse cutaneous reactions induced by systemic drugs were collected in this study. The previous studies were principally done in selected patients hospitalized only in general internal medicine or medical divisions. Our results confirm some data already known about skin drug reactions: HIV infection as a risk factor (P < 0.0001), high prevalence of adverse cutaneous reactions due to antibiotics, and difficulty in ascertaining the imputability of a drug. A high proportion (34%) of these reactions was severe and 15% were avoidable; these two facts justify the development of an intensive programme of clinical pharmacology.
