Influences upon the diffusion of thrombolysis for acute myocardial infarction in England: Case study

  • Alison Cook (a1), Claire Packer (a1), Andrew Stevens (a1) and Tom Quinn (a2)

Abstract

Objectives: To investigate the factors that influenced the adoption and diffusion of thrombolysis in acute myocardial infarction in England and to verify usage data from 1981 to 2001.

Methods: Survey of cardiologists in England using a pre-prepared time line of historical events and a plot of thrombolysis diffusion since 1981. The cardiologists were divided into three groups that were provided with (i) the time line only, (ii) the diffusion curve only, and (iii) the time line and the diffusion curve.

Results: The GISSI and ISIS-2 clinical trials were perceived to have had a significant influence upon the initial diffusion of thrombolysis in England occurring over the 3 years after launch. Other positive influences included the initial listing in the national formulary, the change to administration in emergency departments, the rise in evidence-based medicine, and production of national guidance.

Conclusions: Although it is apparent that the overall influences on adoption and diffusion of thrombolysis were multiple; clinical trials, service developments, and national guidelines all were judged to have played a part. The GISSI and ISIS-2 clinical trials were confirmed as the major influence on initial adoption.
