RESUMO
RATIONALE & OBJECTIVE: Previous studies showing poor cardiopulmonary resuscitation (CPR) outcomes in the dialysis population have largely been derived from claims data and are somewhat limited by a lack of detailed characterization of CPR events. We aimed to analyze CPR-related outcomes in individuals receiving maintenance dialysis. STUDY DESIGN: Retrospective chart review. SETTING & PARTICIPANTS: Using electronic medical records from a single academic health care system, we identified all hospitalized adult patients receiving maintenance dialysis who had undergone in-hospital CPR between 2006 and 2014. EXPOSURE: Initial in-hospital CPR. OUTCOMES: Overall survival, predictors of unsuccessful CPR, predictors of death during the same hospitalization among initial survivors, predictors of discharge-to-home status. ANALYTICAL APPROACH: We provide descriptive statistics for the study variables and used t tests, χ2 tests, or Fisher exact tests to compare differences between the groups. We built multivariable logistic regression models to examine the CPR-related outcomes. RESULTS: A total of 184 patients received in-hospital CPR: 51 (28%) did not survive the initial CPR event, and 77 CPR survivors died (additional 42%) later during the same hospitalization (overall mortality 70%). Only 18 (10%) were discharged home, with the remaining 32 (17%) discharged to a rehabilitation facility or a nursing home. In the multivariable model, the only predictor of unsuccessful CPR was CPR duration (OR, 1.41; 95% CI, 1.24-1.61; P < 0.001). Predictors of death during the same hospitalization after surviving the initial CPR event were CPR duration (OR, 1.15; 95% CI 1.04-1.27; P = 0.007) and older age (OR, 1.64; 95% CI, 1.23-2.2; P < 0.001). Older people also had lower odds of discharge-to-home status (OR, 0.25; 95% CI, 0.11-0.54; P < 0.001). LIMITATIONS: Retrospective study design, single-center study, no information on functional status. CONCLUSIONS: Patients receiving maintenance dialysis experience high mortality following in-hospital CPR and only 10% are discharged home. These data may help clinicians provide useful prognostic information while engaging in goals of care conversations.
