Colorectal Cancer Risk Factors and Screening Among the Uninsured of Tampa Bay: A Free Clinic Study

Abstract

Introduction Uninsured patients with low socioeconomic status are at high risk for developing colorectal cancer (CRC), and data on risk factors and prevalence of CRC in this population are limited. The purpose of this study was to assess the risk factors for CRC in uninsured patients from free clinics in the Tampa Bay area of Florida. Methods We conducted a retrospective cohort study among patients 50 years or older who were provided service at 9 free clinics in the Tampa Bay area between 2016 and 2018. Demographics, chronic disease characteristics, and screening data were collected via a query of paper and electronic medical records. Results Of the 13,982 patients seen, 5,139 (36.8%) were aged 50 years or older. Most were female (56.8%), non-Hispanic White (41.1%), and unemployed (54.9%). Patients with CRC screening were more likely to be employed compared with patients without CRC screening (54.4% vs 44.4%, P = .01). Within the cohort, 725 (22.7%) patients were active smokers, 771 (29.2%) patients currently consumed alcohol, and 23 patients (0.4%) had a history of inflammatory bowel disease. Patients had a median body mass index of 29.4 (interquartile range, 25.4–34.2) kg/m 2 , and 1,455 (28.3%) had diabetes. Documented CRC screening was found among 341 (6.6%) patients. Conclusion Uninsured patients had a high prevalence of CRC risk factors but a low reported screening rate for CRC. Free clinics are uniquely positioned to provide patients at high risk for CRC with strategies to decrease their risk and to be screened for CRC.

Preventative Cancer Screening Rates Among Uninsured Patients in Free Clinics: A Retrospective Cohort Study of Cancer Survivors and Non-cancer Survivors

“…27 The importance of screening uninsured patients for colon cancer was highlighted by a prior study conducted of the entire free clinic population included in our study, and described how risk factors for colon cancer are high amongst this uninsured population. 28 Our study found a significant disparity among the patients who completed cervical cancer screenings compared to the insured population. Our study found that 23.9% of cancer survivors and 20.1% of patients without cancer histories received ageappropriate cervical cancer screenings, and had age-appropriate cervical cancer screenings.…”

Closing the Gap: Approaches to Improving Colorectal Surgery Care for the Uninsured and Underinsured

“…15 16 17 The prevalence of all risk factors is higher among uninsured populations. 18 19 The intersection of neighborhood-level factors, such as access to healthy food, and an individual's insurance status compound risk. For example, uninsured individuals are more likely to live in low-income neighborhoods and food deserts, which have been linked to higher CRC incidence and mortality.…”

“…It is also crucial to recognize the significant impact of socioeconomic inequalities on screening rates because early screening can influence disease incidence, prevalence, and outcomes [24][25][26][27]. Studies have identified several socioeconomic barriers, such as lower educational attainment, income inequality, and limited access to healthcare facilities, contributing to lower screening rates in disadvantaged populations [16,28]. It is important to recognize that these socioeconomic factors may intersect and influence each other (e.g., individuals with lower education levels may also face financial constraints and limited access to healthcare facilities), exacerbating challenges for disadvantaged populations.…”
