In this analysis, 55% of physicians adopted DES for at least 10% of their stent placements within 5 weeks of FDA approval, producing an almost vertical adoption curve for every, suggesting extremely rapid adoption and possible over-adoption of DES. Factors found to be significant in the adoption of DES technology by the earliest innovators were physician competition and the promotion efforts of a change agent. Variables found to be associated with the adoption of DES technology for the majority of adopters were physician competition, communication channels amongst cardiologists, and the promotion efforts of a change agent. The only variable significantly influencing the adoption of DES by physicians at hospitals where early adopting physicians work was physician competition. Within six months of DES technology being approved by the U.S. Food and Drug Administration, 50% of physicians in this study were placing DES in the majority of their patients. Variables found to be associated with the rapid adoption of incremental innovations such as DES can be leveraged by policy makers to shape the diffusion and adoption of new healthcare technologies in the future.While the effect of working at a high volume hospital was associated with a 50% increase in the likelihood of adoption, 40% less than for innovator physicians, being a high volume BMS physician was associated with a 510% (95% C.I. 440% toanbsp;...
