Cancer-attributable costs are calculated as the average monthly difference in costs between CRC cases minus their matched controls multiplied by 12 and inflated to 2014 US dollars. Medicare costs include Medicare payments and patient’s responsibility. CRC = colorectal cancer; EOL = end of life; LIS = Part D low-income subsidy.
†
Initial phase represents the first 12 months after diagnosis, the EOL is defined as the 12 months before death, and the continuing phase is the months between the initial and the EOL phase.
