Background Interventions aimed at improving access to timely cancer care for patients in low‐ and middle‐income countries (LMIC) are urgently needed. We aimed to evaluate a patient navigation (PN) program to reduce referral time to cancer centers for underserved patients with a suspicion or diagnosis of cancer at a public general hospital in Mexico City. Materials and Methods From January 2016 to March 2017, consecutive patients aged >18 years with a suspicion or diagnosis of cancer seen at Ajusco Medio General Hospital in Mexico City who required referral to a specialized center for diagnosis or treatment were enrolled. A patient navigator assisted patients with scheduling, completing paperwork, obtaining results in a timely manner, transportation, and addressing other barriers to care. The primary outcome was the proportion of patients who obtained a specialized consultation at a cancer center within the first 3 months after enrollment. Results Seventy patients (median age 54, range 19–85) participated in this study. Ninety‐six percent (n = 67) identified >1 barrier to cancer care access. The most commonly reported barriers to health care access were financial burden (n = 50) and fear (n = 37). Median time to referral was 7 days (range 0–49), and time to specialist appointment was 27 days (range 1–97). Ninety‐one percent of patients successfully obtained appointments at cancer centers in <3 months. Conclusion Implementing PN in LMIC is feasible, and may lead to shortened referral times for specialized cancer care by helping overcome barriers to health care access among underserved patients. Implications for Practice A patient navigation program for patients with suspicion or diagnosis of cancer in a second‐level hospital was feasible and acceptable. It reduced patient‐reported barriers, and referral time to specialized appointments and treatment initiation were within international recommended limits. Patient navigation may improve access to care for underserved patients in developing countries.

6544 Background: High cancer mortality rates in developing nations are partially driven by advanced stages at diagnosis and limited access to care. In Mexico, the interval from problem identification to start of treatment can be up to 7 months, mostly due to healthcare system delays. We implemented a patient navigation (PN) program aimed at reducing time to referral to cancer centers for patients (pts) with a suspicion or a diagnosis of cancer seen at a public general hospital in Mexico City. Methods: Pts age > 18 seen at Hospital General Ajusco Medio in Mexico City who required referral to a cancer center were enrolled. Baseline demographic, economic and psychosocial data were collected. A Patient Navigator assisted pts with scheduling; paperwork; obtaining results in a timely manner; transportation; and with other cultural barriers. The goal of the PN program was for at least 70% of enrolled patients to obtain a specialized appointment at a cancer center within the first 3 months from enrollment. Results: 53 pts (median age 54, range 19-80; 51% female) were included between 01/16 and 12/16. 19% (n = 10) had breast/GYN, 19% (n = 10) GU, 19% (n = 10) endocrine, 19% GI (n = 10) and 14% (n = 13) other tumors. All the pts were uninsured, 59% (n = 30) had less than middle school education, 80% (n = 41) were unemployed and 96% (n = 49) had a monthly household income of < $360 USD. 54% (n = 28) reported deprivation in at least one basic living need (education, running water, toilet, electricity or flooring). The most commonly identified barriers to healthcare access were financial (73%, N = 37), lack of transportation (47%, N = 24), fear (37%, N = 19) and poor communication with healthcare workers (35%, N = 18). Mean time to referral was 11 days (range 0–46, SD 11.2) and mean time to cancer specialist appointment 26 days (range 1–94, SD 21.18). 92% of pts successfully obtained appointments at a cancer center in < 3 months. Conclusions: Compared with previously reported data, this PN program shortened time to referral to a cancer center for pts with a suspicion or diagnosis of cancer in Mexico City. PN represents a potential solution to overcome barriers to healthcare access for underserved pts with cancer in developing countries.
