Objective To ascertain whether a name can influence a person’s health, by assessing whether people with the surname “Brady” have an increased prevalence of bradycardia.
Design Retrospective, population based cohort study.
Setting One university teaching hospital in Dublin, Ireland.
Participants People with the surname “Brady” in Dublin, determined through use of an online telephone directory.
Main outcome measure Prevalence of participants who had pacemakers inserted for bradycardia between 1 January 2007 and 28 February 2013.
Results 579 (0.36%) of 161 967 people who were listed on the Dublin telephone listings had the surname “Brady.” The proportion of pacemaker recipients was significantly higher among Bradys (n=8, 1.38%) than among non-Bradys (n=991, 0.61%; P=0.03). The unadjusted odds ratio (95% confidence interval) for pacemaker implantation among individuals with the surname Brady compared with individuals with other surnames was 2.27 (1.13 to 4.57).
Conclusions Patients named Brady are at increased risk of needing pacemaker implantation compared with the general population. This finding shows a potential role for nominative determinism in health.
