Abstract

BACKGROUND: Cardiopulmonary arrest is known to have a poor prognosis, further worsened by preexisting comorbidities. With improved treatment, the prevalence of metastatic cancers is rapidly increasing; however, the outcomes of in-hospital cardiopulmonary resuscitation (ICPR) remain to be well described. This study examines the epidemiology, associations, and outcomes of ICPR in these patients.

METHODS: This is a retrospective cohort analysis of the Nationwide Inpatient Sample database (2012-2014) including patients aged ≥18 years with metastatic cancers. Primary outcome was inpatient mortality following ICPR. Factors associated with the primary outcome were analyzed using univariate/multivariate logistic regression analysis.

RESULTS: Among all admissions with metastatic cancers (n = 5,500,684), 0.47% (n = 26,070) received ICPR. Inpatient mortality was 81.77% (n = 8905) versus 68.90% among those without metastatic solid cancers and receiving ICPR. Inpatient palliative care encounter was documented in 18.95% of patients with metastatic cancer who received ICPR. On multivariate logistic regression, some of the notable factors associated with higher mortality included being of African American or Hispanic race and hospital admission over the weekend. Factors associated with lower mortality included female sex, elective admission, and head and neck as the primary site. Admissions with ICPR were associated with higher mean total charge of hospitalization (by $48,670) compared with admissions without ICPR. Of those who survived ICPR, 43.82% were transferred to another facility after discharge.

CONCLUSIONS: Among adult patients with metastatic solid cancers having ICPR, 81.8% died within the same hospital admission. Race and admission type predicted mortality. Despite known poor prognosis, only a minority had palliative care.

LAY SUMMARY: Cardiopulmonary resuscitation during hospitalization for patients who have metastatic cancer has a very poor outcome with a mortality rate of 81.77%. Inpatient cardiopulmonary resuscitation in these patients is also associated with a significantly higher cost of care, longer length of stay, and high rate of transfer to a different health care facility upon discharge. Knowledge of these outcomes is helpful in discussing the pros and cons of pursuing aggressive resuscitative interventions with patients and families.
