Disparities in Utilization of Medical Specialists for Colonoscopy

Factors Affecting the Rate of Colonoscopy Among African Americans Aged Over 45 Years

African Americans continue to have a low rate of colonoscopy screening despite the U.S. Preventive Services Taskforce's (USPSTF) recommendations and its proven benefits. Colonoscopy has proven to be an effective screening and therapeutic procedure. Understanding the root cause of the problem is a crucial step toward achieving the desired colonoscopy rate among this population. This paper evaluates factors that contribute to the underutilization of colonoscopy. The paper also analyzes strategies that could be maximized to increase colonoscopy rates, minimize colorectal cancer inequalities, and promote optimal colorectal health among African Americans.

Distance and Transportation Barriers to Colorectal Cancer Screening in a Rural Community

Rural residents in underserved areas face many barriers to health services, including colonoscopies for colorectal cancer (CRC) screening, but rural healthcare providers may assist patients navigating these challenges due to familiarity with local contexts. In 2017 to 2018, we interviewed clinical practitioners and staff (n = 40) at 13 primary care and gastroenterology locations across rural Southern Illinois. We used a semi-structured interview guide that addressed system, provider, and patient levels including domains related to barriers, facilitators, and needs for intervention. This article focuses on 3 main elements related to distance and transportation that emerged from inductive coding. First, providers described long distance travel for care as normalized but not necessarily preferable. Second, they identified and described distance-related challenges specific to CRC screening, and third, providers discussed strategies, mostly related to transportation, they use to navigate those challenges. Finally, they suggested a variety of broader solutions to reduce distance and transportation barriers to screening. Overall, distance to care remains a challenge to increasing CRC screening and contributes to disparities in rural communities. To increase early detection and reduce rural cancer disparities, efforts to increase screening and follow-up must address ways to help patients and providers navigate this distance within their local communities and contexts.

Racial Disparities in Colorectal Cancer Care for Black Patients: Barriers and Solutions

Racial disparities in colorectal cancer for Black patients have led to a significant mortality difference when compared to White patients, a gap which has remained to this day. These differences have been linked to poorer quality insurance and socioeconomic status in addition to lower access to high-quality health care resources, which are emblematic of systemic racial inequities. Disparities impact nearly every point along the colorectal cancer care continuum and include barriers to screening, surgical care, oncologic care, and surveillance. These critical faults are the driving forces behind the mortality difference Black patients face. Health care systems should strive to correct these disparities through both cultural competency at the provider level and public policy change at the national level.

Rural and racial disparities in colorectal cancer incidence and mortality in South Carolina, 1996 - 2016

PURPOSE

Colorectal cancer (CRC) is the third leading cause of cancer mortality among men and women in the United States and South Carolina (SC). Since SC has one of the highest proportions of Black (27.9%) and rural residents (33.7%), the purpose of this investigation was to describe the burden of CRC on racial disparities in rural populations.

METHODS

Count data from 2012 to 2016 were obtained from the state central cancer registry using an online data retrieval system. Rural-urban status was determined using Urban Influence Codes (1-2 = urban; 3-12 = rural). Chi-square tests were calculated to examine differences in CRC stage by rurality and race. Annual percent change and annual average percent change (AAPC) were calculated to examine trends in incidence and mortality rates across rural-urban and racial groups between 1996 and 2016.

RESULTS

Areas with high mortality-to-incidence ratios tended to be in rural counties. Furthermore, rural residents had higher proportions of distant stage CRC compared to urban residents, and Black populations had higher proportions of distant stage CRC compared to White populations (22.7% vs. 26.3% and 29.3% vs. 23.7%, respectively; P value < 0.05). From 1996 to 2016, Black and White urban-dwelling residents experienced a significant decline in incidence. Urban White, urban Black, and rural White populations experienced significant declines in mortality (AAPC = -2.6% vs -2.4% vs -1.6% vs -0.9%, respectively).

CONCLUSIONS

Despite improvements in CRC screening in recent decades, focused evidenced-based interventions for lowering incidence and mortality among rural and Black populations in South Carolina are necessary.
