De-escalating treatments and transitioning care in a cardiac intensive care units network

Abstract

Abstract Funding Acknowledgements None. Background Recent data (1) have shown that end-of-life (EOL) management of patients with acute decompensated heart failure (ADHF) in Cardiac Intensive Care Units (CICU) is aggressive, with late or no involvement of palliative care (PC) teams. Purpose To evaluate current PC and EOL practices in a contemporary multicenter registry of patients with ADHF who deteriorated to cardiogenic shock (CS). Methods A survey-based approach was used to collect data on PC and EOL management practices. We enrolled CS patients from 12 participating centers. A subset of 153 patients with ADHF-CS, enrolled between March 2020 and March 2023, was analyzed. We asked participating centers to report their practice regarding de-escalating treatments and transitioning care in the context of EOL, focusing on 1) discussion of implantable cardioverter defibrillator (ICD) deactivation with patients, 2) documentation of do-not-resuscitate (DNR) orders in the patient's medical record, and 3) documentation of advance directives in the patient's medical record. We also examined early PC team involvement and ICD deactivation as indicators of de-escalating treatments and transitional care in ADHF-CS. Results are presented as numbers and percentages (%) for categorical variables and medians (interquartile range, IQR) for continuous variables. Results Baseline characteristics of the population are shown in Table 1. Figure 1 describes the practices of the participating centers. DNR was routinely documented in the medical records in only 5 of 12 centers (41.7%). PC teams were involved in 21 of 153 enrolled ADHF-CS patients (13.7%). Of the 51 patients with an ICD, 17 died: 13 patients (76%) died in the hospital and 4 (24%) died within 6 months of discharge. ICD deactivation occurred in 6 of 17 deceased patients (35.3%). One patient had ICD deactivation supported by home PC services. Conclusions This study shows that the practice of de-escalating therapy, including ICD deactivation, is not routine in the participating centers. Our findings highlight the importance of integrating PC as a concurrent process with intensive care to effectively address the unmet needs of these patients and their families.
