Quality of end-of-life care for veterans with metastatic cancer and advanced chronic kidney disease.

Abstract

e18281 Background: Patients with cancer receive less aggressive interventions and higher quality end-of-life care than those with advanced chronic kidney disease (ACKD). However, the relationship between ACKD and cancer and patterns and quality of end-of-life care is poorly understood. Methods: Among a retrospective cohort of all patients with ACKD (estimated glomerular filtration rate < 20 mL/min/1.73m2) who died in Veterans Affairs facilities between 2009-2015 ( N = 9993), we compared dialysis treatment patterns, end-of-life care and family rated quality of care among those who did and did not have a diagnosis of metastatic cancer during the year before death. Data sources included Veterans Affairs clinical and administrative data, Medicare claims, and the United States Renal Data System registry. Family ratings of end-of-life care were based on responses to the Bereaved Family Survey (BFS). We fit logistic regression models and converted the coefficients to predicted probabilities Results: Overall, 1,237(12.4%) patients had a diagnostic code for metastatic cancer during the year before death. These patients were less likely than other patients to have been treated with dialysis before death. In analyses adjusted for patient characteristics and dialysis receipt, patients with metastatic cancer were less likely than other patients to receive intensive procedures (predicted probability: 18.2% vs. 36.2%) and to be admitted to the intensive care unit (ICU) within 30 days of death (30.7% vs. 50.1 %), or die in the ICU (16.2% vs. 33%). These patients were also more likely to receive a palliative care consultation within 90 days of death (46.6% vs. 37%) and to have hospice services at the time of death (55.3% vs. 33.4 %). Family-rated overall quality of care was higher for those with metastatic cancer (59.6% vs. 54.1%). Family members of patients with metastatic cancer also provided more favorable ratings for five individual BFS items including provider listening, informational, emotional support before death and pain control. All comparisons were statistically significant (i.e., P < 0.05). Conclusions: Within a national cohort of US Veterans with ACKD, the presence of metastatic cancer was associated with less dialysis utilization, less intensive medical care, and significantly higher bereaved family ratings of end-of-life care.
