Abstract

Objective:

To evaluate the long-term survival rate of critically ill sepsis survivors following cardiopulmonary resuscitation on a national scale.

Design

Retrospective and observational cohort study.

Setting

Data were extracted from Taiwan’s National Health Insurance Research Database.

Patients

A total of 272,897 ICU patients with sepsis were identified during 2000-2010. Patients who survived to hospital discharge were enrolled. Post-discharge survival outcomes of ICU sepsis survivors who received cardiopulmonary resuscitation were compared with those of patients who did not experience cardiopulmonary arrest using propensity score matching with a 1:1 ratio.

Intervention

None.

Measurements and Main Results:

Only 7% (n = 3,207) of sepsis patients who received cardiopulmonary resuscitation survived to discharge. The overall 1-, 2-, and 5-year postdischarge survival rates following cardiopulmonary resuscitation were 28%, 23%, and 14%, respectively. Compared with sepsis survivors without cardiopulmonary arrest, sepsis survivors who received cardiopulmonary resuscitation had a greater risk of all-cause mortality after discharge (hazard ratio, 1.38; 95% CI, 1.34–1.46). This difference in mortality risk diminished after 2 years (hazard ratio, 1.11; 95% CI, 0.96–1.28). Multivariable analysis showed that independent risk factors for long-term mortality following cardiopulmonary resuscitation were male sex, older age, receipt of care in a nonmedical center, higher Charlson Comorbidity Index score, chronic kidney disease, cancer, respiratory infection, vasoactive agent use, and receipt of renal replacement therapy during ICU stay.

Conclusion:

The long-term outcome was worse in ICU survivors of sepsis who received in-hospital cardiopulmonary resuscitation than in those who did not, but this increased risk of mortality diminished at 2 years after discharge.
