Extract

This article reviews nonexperimental data bases, emphasizing the present uses and future opportunities of routinely collected information. Data bases are discussed in terms of appropriate research designs. Possibilities for expanding available information through new data collection and through record linkage are stressed. The relationship of nonexperimental data systems to randomized trials and to clinical decision-making is examined.
