Abstract
The need for accurate systematic information to inform not only clinical practice and health-services management but also evaluation research and clinical audit is now well recognised. Less well recognised are the benefits that could result if the proponents of each of these activities combined their resources to obtain the data they need. Irrespective of the uses to which they wish to put the data, clinicians, managers, consumers, and researchers all need data, from consecutive cases, that are complete and accurate, that are based on standard definitions of clinical disorders, interventions, and outcomes, and that include information on those characteristics of patients that affect outcome. Anyone familiar with administrative data collected routinely in most health systems will recognise the inadequacy of information from such sources. In response to such failings, groups of clinicians in many countries have established their own high-quality clinical databases (HQCDs). 1 Pryor DB Califf RM Harrell FE et al.
