Aim: Little is known regarding the extent to which dying patients with chronic obstructive pulmonary disease (COPD) receive life-sustaining procedures and palliative care in US hospitals. We examined temporal trends and the impact of palliative care on the use of life-sustaining procedures in this population. Materials and Methods: A retrospective nationwide cohort analysis was performed using weighted National Inpatient Sample (NIS) data obtained from 2010 to 2014. Decedents _18 years of age at the time of death and with a principal diagnosis of COPD were included. We examined the receipt of life-sustaining procedures, defined as1 ventilation (intubation, mechanical ventilation, and noninvasive ventilation),2 vasopressor use (infusion and intravascular monitoring),3 nutrition (enteral and parenteral infusion of concentrated nutrition),4 dialysis, and5 cardiopulmonary resuscitation as well as palliative care consultation and do not resuscitate (DNR). We used compound annual growth rates (CAGRs) and the Rao-Scott correction of the w2 statistic to determine the statistical significance of temporal trends of lifesustaining procedures, palliative care utilization, and DNR status. Results: Among 37 312 324 hospitalizations, 38 425 patients were examined. The CAGRs of life-sustaining procedures were 6.61% and _9.73% among patients who underwent multiple procedures and patients who did not undergo any procedure, respectively (both P <.001). The CAGRs of palliative consultation and DNR were 5.25% and 36.62%, respectively (both P <.001). Conclusions: Among adults with COPD dying in US hospitals between 2010 and 2014, the utilization of life-sustaining procedures, palliative care, and DNR status increased.
