Abstract [en]

Advances in biomedical engineering enable us to treat increasingly severe conditions. This implies an increased need for regulation and priority setting in healthcare, to ensure appropriate safety cautions and to avoid accelerating expenditures. This interview study investigates the mechanisms behind the adoption and use of medical devices through the subjective experiences of hospital staff working with devices for neonatal intensive care. The adoption was found to be primarily initiated by vendor activities, but professionals preferably sought information about functionality from close colleagues. Full integration of devices was sometimes not achieved, and even though the adopting units had good introduction routines, there was no systematic follow-up of how adopted devices had been integrated in the work practices. Diffusion variations were, however, mainly found for temporarily tested devices and not for permanently available technologies. Three factors were found to be the major explanatory variables of the adoption of medical devices: (1) the subjective expected value of the device, (2) information and learning, and (3) the innovativeness of the adopting unit.

Abstract [en]

An increased use of medical devices has been assumed to be a major cause of rising healthcare expenditures. Nations around the world are trying to keep costs down, but strong incentives still exist for the development and use of new devices. Innovation is, however, never exclusively good or bad and it is not easy to evaluate the net effect. Theories and empirical research on innovation have been produced for more than 100 years. In this, the diffusion of innovations has attracted the most interest, while other areas, such as the integration of technologies, have been less thoroughly researched.

This thesis presents a model of medical device innovation in hospitals – from the first idea and invention effort to regular use of a new technology. The suggested model is built on three fundaments: (1) academic innovation literature, (2) empirical studies, and (3) observations of on-going innovation processes. The model is a synthesis of the accumulated knowledge in different innovation research traditions, and of empirical studies of the Swedish healthcare system and the medical device industry. The aim is to give a comprehensive picture of the innovation process, and to provide a theoretical model, which can be used for studying and influencing the paths of medical device innovations into healthcare practice.

In order to achieve a balanced rate of change, with long-term societal benefits, an inter-disciplinary approach is necessary in the planning and regulation of medical device innovation. The new model combines academic views with political/entrepreneurial and healthcare views. Innovation, in this model, is suggested to occur in three integrated activity domains: invention, diffusion, and deployment. A great number of factors that influence these activities are investigated and described, and different roles and incentives are discussed. Deviations from traditional innovation theory are for example: (a) integration of invention activities as having an impact on later events; (b) inclusion of the inventor/developer as a main actor also in the diffusion and deployment domains; (c) increased focus of the concept of technology cluster innovation, and (d) the rationality of use and abandonment of knowledge as factors to be included in the estimation of consequences of innovation.

Finally, the thesis suggests a number of model and methodology improvements and policy implications for management of innovation in hospitals.
