Twenty-two physicians who implanted cardiovascular (pacemakers, ICDs and stents) and orthopaedic devices (largely hip/knee implants) were interviewed (Table 1). These included 8, 10 and 4 early, mid and late career physicians, respectively, from 5 provinces, and each was from a different hospital. Supplementary Table 1 presents all themes and exemplar quotes. Select quotes are discussed here to illustrate themes, discrepant views and participant characteristics associated with discrepant views.
