e18136 Background: Colombia has gone to great lengths to provide nearly universal health care insurance for its patients, as 96.6% of its constituents now have health insurance as of 2014 compared to 23.5% in 1993. Most Colombians are associated with either contributive insurance (CI) in which employees and employers contribute to the insurance or subsidized insurance (SI) in which government funds cover the insurance cost. Colorectal cancer (CRC) has the 5th highest incidence of all malignancies in Colombia. This abstract aims to compare CRC care delivery metrics between CI and SI. Methods: We used the Colombian National Administrative Cancer Registry (NACR) data compiled from the Department of Health Ministry from January 2, 2016- January 1, 2017 consisting of 32 departments and 1122 municipalities. CRC cases were investigated by incidence, mortality, percentage of cases with early stage detection, stage I-III with curative surgery intent, nutritional support, and TNM staging, and days between suspicion to diagnosis, diagnosis to first treatment, neoadjuvant therapy to surgery, and surgery to adjuvant therapy. Results: There were 2605 new CRC cases in the NACR in 2017, with 1691 CI cases and 823 SI cases. There was a noticeably higher incidence in CI (7.2 new cases per 100,000 people) than in SI (3.7 new cases per 100,000), and a higher mortality rate (5.0 deaths per 100,000) in CI compared with SI cases (2.6 deaths per 100,000). There was a significant increase in average wait time for SI CRC cases from diagnosis to first treatment (77.7 days vs. 57.3 days, p = .027) and in average time to neoadjuvant therapy to surgery in CI cases (123.1 days vs. 92.5 days, p = .054) with longer but statistically insignificant wait times in SI cases in average time to adjuvant therapy (83.6 days vs. 73.9 days, p = .0168) and suspicion to diagnosis (56.1 days vs. 46.9 days, p = .811). Similar percentages of CI and SI cases had early stage detection (37.2% in SI vs. 34.3% in CI, p = 0.311), TNM staging (50.7% in CI vs. 49.3% in SI, p = 0.146), stage I-III cases with curative surgery intent (23.3% in CI vs. 21.8% in SI, p = 0.833), and nutritional support (10.5% in CI vs. 8.5% in SI, p = 0.942). Conclusions: The NACR represents a model for developing countries to improve cancer care delivery efficiently. As evidenced by higher incidence and mortality in CI cases and longer wait times before treatment in SI cases, there are differences in cancer care delivery between major modes of healthcare delivery in Colombia. More investigation needs to be done with a goal of streamlining cancer care delivery.
