The purpose of this report is to determine what effect filmless operation has on technologist productivity when compared with traditional film-based operation. Retrospective data on technologist productivity was collected from the study institution before and after implementation of PACS using workload reports and payroll records. Departmentwide technologist productivity was defined as the number of examinations per full-time equivalent (exams/FTE) and correlated with local and nationwide standards operating in traditional film-based operations. During film-based operation, technologist productivity was comparable between the study institution and nationwide standards, allowing for the unique examination volumes and modality mix. After implementation of a large-scale PACS, technologist productivity was found to increase 34% above that of national standards and 48% that of the local control site. Implementation of an enterprisewide PACS offers the potential to significantly improve departmentwide technologist productivity when compared with traditional film-based operation.

While there has been an important increase in methodological and empirical studies on health inequality, not much has been written on the theoretical foundation of health inequality measurement. We discuss several reasons why the classic welfare approach, which is the foundation of income inequality analysis, fails to provide a satisfactory foundation for health inequality analysis. We propose an alternative approach which is more closely linked to the WHO concept of equity in health and is also consistent with the ethical principles espoused by Rawls [A Theory of Justice. Harvard University Press, Cambridge, MA, 1971]. This approach in its simplest form, is shown to be closely related to the concentration curve when health and income are positively related. Thus, the criteria presented in our paper provide an important theoretical foundation for empirical analysis using the concentration curve. We explore the properties of these approaches by developing policy scenarios and examining how various ethical criteria affect government strategies for targeting health interventions.
