Emergency Presentation and Short-Term Survival Among Patients With Colorectal Cancer Enrolled in the Government Health Plan of Puerto Rico

OBJECTIVE In this study, we examine factors associated with the use of the emergency room (ER) as an entry point into the health-care system to initiate a cancer diagnosis among Puerto Rico's Government Health Plan (GHP) patients and compare the 1-year survival of GHP patients that initiated cancer diagnosis in the emergency room (ER) presentation with those that initiated the diagnosis in a physician's office. METHODS Data for patients with colorectal cancer (CRC) aged 50 to 64 years and diagnosed in 2012 were obtained from the Puerto Rico Central Cancer Registry and linked to the Puerto Rico Health Insurance Administration database (n = 190). Crude odds ratio, adjusted odds ratio, and their 95% confidence intervals were reported. We used the Kaplan-Meier method to generate survival curves. Multivariate Cox regression analysis was performed to evaluate the association between ER presentation and 1-year cause-specific survival. RESULTS We found that 37.37% of the study population had an ER presentation. Male patients had a higher occurrence of having an ER presentation (66.20%), while 76.06% of the patients with an ER presentation were diagnosed in late stage. Emergency room presentation was a highly predictive factor for cancer mortality in the year following the diagnosis. These patients had between 3.99 to 4.24 times higher mortality risk than non-ER presentation patients (P < .05). CONCLUSION Late presentation for CRC diagnosis through an ER visit is a significant concern that influences negatively on the patient's outcome. Efforts at increasing primary care visits and routine screening tests among GHP beneficiaries could improve survival.
