The human 4 hour patch test provides an opportunity to identify substances with significant skin irritation potential without recourse to the use of animals. The protocol is designed to avoid the production of more than mild irritant reactions and meets the highest ethical standards. This paper provides the background to the development of the method and comments on its performance in the light of recent intra- and inter-laboratory investigations. In particular, the value of the method in providing 'gold standard' data for the identification of those substances (or preparations) which should, or should not, be classified as irritant to skin in European legislation is discussed. On the basis of the published data and supplementary investigations, recommendations are made on both the conduct and interpretation of the human 4 hour patch test. Finally, the lack of any necessity for formal validation of this assay is addressed.
Policy questions associated with the conduct of outcomes studies are addressed and outcomes management and outcomes research are differentiated. Multiple outcomes initiatives are being undertaken in the United States, from the institutional to national and international levels. Nurses have had limited involvement, thus far-although the array of outcomes being examined is considerable. Members of an American Academy of Nursing expert panel on quality health care discuss the environmental context and multiple focuses of outcomes analysis. They provide an overview of current activities, present the challenges confronting nursing in its pursuit of a quality assessment agenda, and make recommendations for increasing nurses' participation in quality initiatives.
