Abstract 10862: Driving Restrictions in ICD Recipients are only Necessary Following Appropriate Shock.
Introduction: Worldwide, implantable cardioverter defibrillator (ICD) recipients are restricted from driving for a certain period of time after implantation. This restriction period is based on the assumed higher incidence of appropriate shocks following ICD implantation.
Objective: To asses the annual risk of harm to other road users with different periods of driving restriction in primary or secondary ICD patients.
Methods: All patients who underwent primary or secondary prevention ICD implantation at the Leiden University Medical Center were included in the study and evaluated for the occurrence of appropriate shocks during follow-up. Incidence of appropriate shocks was assessed following ICD implantation and following first appropriate shock. Taking in account the incidence of first appropriate shock during short term (1 month) and long term (12 months) follow up, the yearly risk of harm (RH) posed by a driver was expressed per 100 000 ICD recipients.
Results: A total of 2574 patients receiving an ICD for primary (n=1584) or secondary (n=990) prevention were included in the analysis. In the primary prevention group, marginal increase in the risk of harm to other road users was observed during short term follow up (RH=2) when compared with long term follow up (RH=1). Similar minor increase was found in the secondary prevention group when short term follow up (RH=5) was compared with long term follow up (RH=2). Following appropriate shock, significant reduction in the risk of harm to other road users was found in the primary group short term follow up (RH=25) when compared with long term follow up (RH=6) and in the secondary group short term follow up (RH=23) when compared with long term follow up (RH=8).
Conclusions: Driving restrictions in both primary and secondary prevention ICD recipients following implantation are unnecessary. However, driving restrictions following appropriate ICD shock could significantly reduce the potential harm to other road users.
