Adapting the Elixhauser comorbidity index for cancer patients.
This study was designed to adapt the Elixhauser comorbidity index for 4 cancer-specific populations and compare 3 versions of the Elixhauser comorbidity score with 3 versions of the Charlson comorbidity score for predicting 2-year survival with 4 types of cancer. Using data from the Texas Cancer Registry-linked Medicare data from 2005 to 2011, the researchers found that cancer-specific Elixhauser comorbidity scores performed slightly better than cancer-specific Charlson comorbidity scores. Individual Elixhauser comorbidities performed best.

Trends in end-of-life cancer care in the Medicare program.
The researchers sought to examine contemporary trends in end-of-life cancer care and geographic variation of end-of-life care aggressiveness among Medicare beneficiaries. They found that the proportion of beneficiaries receiving at least one potentially aggressive end-of-life intervention increased in repeated hospitalization, repeated ED visits, ICU admissions, and late hospice enrollment but declined in in-hospital death. End-of-life chemotherapy use did not change significantly over time. They concluded that despite growing focus on providing appropriate end-of-life care, there has not been an improvement in aggressive end-of-life cancer care in the Medicare program.
