Selection of needlestick prevention devices: a conceptual framework for approaching product evaluation.
Needlestick injuries have been associated with blood-borne disease transmission to health care workers. A demand for a safer work environment has contributed to a proliferation of "safety" products. The selection and evaluation of these devices differs from traditional product evaluation in that it considers not only effectiveness in patient care but also health care worker safety and cost-effectiveness in terms of prevention gained. In addition, multiple devices associated with injuries and choices between passive, active, and accessory safety options require that institutions establish priorities for focusing intervention efforts. Selection of products must involve the primary users. Unless new devices are found acceptable for patient care, health care workers are likely to reject them, despite any apparent safety advantages. Five project steps help define a systematic approach for this process: (1) creation of a multidisciplinary team, (2) defining prevention priorities on the basis of collection and analysis of an institution's injury data, (3) development of design and performance criteria for product selection according to needs for patient care and health care worker safety, (4) planning and implementing an evaluation of products in clinical settings, and (5) analyzing product performance and cost-effectiveness to choose the product. Several methodologic issues raise questions for future research in the area of product evaluation, including the selection of study populations, methods of product distribution and data collection, and influence of institutional culture. In addition, there is a need to develop product-specific design and performance criteria by which evaluation teams can measure various technologies under consideration. Standardization of the product evaluation process for needlestick prevention technology should lead to the collection of information that can be compared across institutions. Infection control professionals have an important opportunity to assume a leadership role in this process.
