The Presence of Implantable Cardioverter Defibrillators is Rarely Addressed During Code Status Change

Background: Implantable Cardioverter Defibrillators (ICDs) are used to prevent sudden cardiac death, but they may provide unwanted shocks during end-of-life care. We aimed to study the frequency at which Do Not Resuscitate (DNR) discussions address ICD preferences in high-risk patients. Methods: A retrospective chart review was performed on patient hospitalizations with the presence of an ICD, a change in code status to DNR, and a subsequent death during that hospitalization. Data collected included demographics, significant comorbidities, if and when ICD was discussed, and who performed code status discussions, and were analyzed for statistical significance. Results: 129 patients met study criteria, and 110 patients (85.3%) did not have a documented discussion addressing ICD deactivation. There were no statistically significant differences in patient characteristics between patients with ICD addressed or not addressed, nor were there differences noted between discussions performed by residents vs staff or with the presence of cardiology, critical care status, or with palliative care consultation. It was noted that specifically discussing intubation or cardioversion was associated with the discussion of ICD deactivation. Conclusion: ICD discussions were rarely documented in our high-risk population, highlighting a potential need for better in-chart visibility of ICDs and for focused education of clinicians who care for these patients at end of life.
