“Whether something cool is good enough”: The role of evidence, sales representatives and nurses' expertise in hospital purchasing decisions

The emphasis on “value” within healthcare institutions has achieved unprecedented priority, particularly around the purchase of medical products and equipment. Health systems and institutions are implementing formal decision-making processes involving clinicians and supply chain professionals to rationalize purchasing and promote cost-effective investment. One particular form of this process is the “Value Analysis” process. Drawing from fieldwork (100 h), interviews (n = 51) and focus groups (n = 4) conducted from January 2012 to October 2014 at 4 acute care hospitals in the western United States, I analyze the ways that committee members constructed and evaluated a case for a product's value. Participants (n = 72) were a purposive sample including nurses, administrators, supply chain and industry professionals. Interpretive phenomenology served as the analytic approach to generating iterative themes. While trying to be evidence-based, Value Analysis committees lacked data related to a product's price or efficacy and relied heavily on local knowledge and expertise. Sales representatives were an integral part of the process, creating interest in the product and providing product information. As vehicles for cost-savings and quality improvement, purchasing committees need unique support that emphasizes local contexts and expertise, while maintaining rigor and minimizing bias. Drawing from participants' experiences, and principles of health technology assessment and economic evaluation, a guiding framework is proposed to support this decision-making.
