Abstract 15101: Return-to-Work for Patients in High-Risk Professions Diagnosed With a Sudden Death-Predisposing Genetic Heart Disease

Abstract

Introduction: Sudden cardiac arrest (SCA) and death (SCD) are the most serious sequelae of many genetic heart diseases (GHDs). Increased awareness of this has led to increased detection in employment screenings. For patients in high-risk jobs, premature and potentially unnecessary termination from their profession, rather than “Return-to-Work (RTW),” has become an undesired consequence of this awareness. The objective of this study is to evaluate the outcomes of patients with GHDs in high-risk professions who were allowed to RTW. Methods: We performed a retrospective review of 3,641 working-age patients referred for evaluation of a potential GHD between 6/2000-12/2021 to identify those either in or being recruited into a high-risk profession. A profession was defined as “high-risk” if it is safety-sensitive or required regular medical evaluations. Charts were reviewed for medical history, RTW decision making, and breakthrough cardiac events (BCEs). Results: Overall, 33 patients [(0.9%); 3 females (9%); mean age at diagnosis 25 ± 15 years] had been either put on hold from their high-risk job (n = 15; 45%) or disqualified as a recruit (18; 55%) prior to our evaluation due to their GHD diagnosis. This included 15 military, 10 pilots, 6 law enforcement and first responders, and 2 commercial driver license professionals and recruits. Most patients were diagnosed with Long QT syndrome (n = 23; 70%). After treatment initiation, 14 (93%) professionals and 16 (89%) recruits received physician RTW approval while 3 (9%) patients did not receive RTW approval due to disease severity and/or unwillingness to initiate treatment. Of the remaining 14 professionals that received physician RTW approval, 4 (29%) were not allowed to return to their jobs, while 14/16 recruits (88%) were not permitted to start their career. None of the RTW-approved patients had a BCE after evaluation (160.7 follow-up years). Conclusions: Patients with GHDs in high-risk professions are often terminated due to perceived SCA/SCD risk. However, within our small cohort, the risk of BCEs in optimally treated patients was low. This data suggests that the certification process of individuals in these high-risk and safety-sensitive occupations should be further examined and potentially modified.
