A Case Study of Physician Interaction in the Medical Device Development Process

Abstract

A multiphase empirical field study is being conducted at Stanford University to examine the process of physician interaction during medical device development. The initial component of this study involved creating an analytic framework for case-based research that provided a conceptual guide for the pilot case study documented in this paper. The pilot case study examined the process of engaging physicians in medical device development within the context of an entrepreneurial device company. The methods used in this study included a combination of interviews with cross-functional team members, a quantitative survey, and the collection of archival data. Data analysis first involved documenting physician-developer interaction practices that had been used within the company, from needs finding to post-market surveillance, across multiple product generations. Leading development factors involving physicians that had influenced the company’s clinical and financial outcomes were next identified. The case study illustrated the importance of working with and understanding the user experiences of a wide range of physicians when developing new products. The case also captured how physician interaction influences risk perceptions toward medical device performance for both surgeons and developers. The case likewise highlighted the benefits of a systems-based design approach, as opposed to designing products for a single technical end point. From a methodological perspective, the case study revealed the importance of examining user interaction within a contextual framework, as opposed to an isolated examination of input and output variables. The study presented in this paper has provided a foundation for future case-based analyses regarding the process of physician interaction in medical device development.
