Disparities in Screening Mammography Utilization Among Hispanic Women in Rural Texas From 2002 to 2018

PURPOSE: To examine the trends of racial/ethnic and urban-rural disparities in screening mammography use with a focus on Hispanic women in rural Texas, as well as to further investigate barriers to mammography screening practices. METHODS: A serial cross-sectional study was conducted on screening mammography including eligible female respondents (≥ 40 years) from the Texas Behavioral Risk Factor Surveillance System survey from 2002 to 2018. FINDINGS: Weighted descriptive analyses showed persistent racial/ethnic and urban-rural disparities in mammography screening rates among eligible women (≥ 40 years) in Texas. Overall, the mammography screening rates for women in rural areas were significantly lower than women in urban areas with a mean rate of 64.09% versus 70.89% (p \u3c 0.001). Rural Hispanic women had the lowest mean mammography screening rate (55.98%) among all eligible women which is 16.27% below the mean mammography screening rate of non-Hispanic white women in urban areas. Weighted logistic regression model revealed that women with no health insurance or primary care providers were 52% (95% Confidence Interval [CI] 0.36-0.63, p \u3c 0.001) or 54% (95% CI 0.35-0.6, p \u3c 0.001) less likely having an up-to-date mammography screening compared with women with health insurance or primary care providers, respectively. CONCLUSIONS: Our study demonstrated significant and persistent racial and urban-rural disparities in screening mammography utilization among Hispanic women compared with non-Hispanic white women from 2002 to 2018. Healthcare access is a major contributor to these disparities. It highlights the need for wide-scale interventions from public health and policymakers targeting under screened racial minorities and rural regions population to promote screening mammography services among disadvantaged population

Rural Racial Disparities and Barriers in Mammography Utilization Among Medicare Beneficiaries in Texas: A Longitudinal Study

This study examined rural racial/ethnic disparities in long-term mammography screening practices among Medicare beneficiaries. A retrospective longitudinal study was conducted using 100% Texas Medicare data for women aged 65-74 who enrolled in Medicare between 2010-2013. Of the 114,939 eligible women, 21.2% of Hispanics, 33.3% of non-Hispanic Blacks (NHB), and 38.4% non-Hispanic Whites (NHW) in rural areas were regular users of mammography, compared to 33.5%, 44.9%, and 45.3% of their counterparts in urban areas, respectively. Stratification analyses showed rural Hispanics and NHB were 33% (95% CI, 25% - 40%) and 22% (95% CI, 6% - 36%) less likely to be regular users of mammography compared to their urban counterparts. Major barriers to routine mammography screening included the lack of a primary care provider, frequent hospitalization, and comorbidity. The findings of this study highlight the importance of addressing rural racial disparities in mammography utilization among older women to ensure equitable screening practices for all populations

Adjuvant 5-Fluorouracil/Leucovorin, Capecitabine, and Oxaliplatin-Related Regimens for Stage II/III Colon Cancer Patients 66 Years or Older

Adjuvant chemotherapy of leucovorin-modulated 5-fluorouracil (5-FU/LV), capecitabine, and adding oxaliplatin to 5-FU/LV or capecitabine (FLOX/OX) have been standard regimens for high-risk stage II or III colon cancer (CC). We aimed to evaluate their patterns of use, association with survival, and rate of emergency room visit (ER) or hospitalization during the treatment period. High-risk stage II or III patients aged \u3e65 years diagnosed between 2007 and 2015, underwent colectomy, and received any of these three regimens were selected from SEER and Texas Cancer Registry (TC) linked with Medicare data. Chi-square test, Kaplan-Meier survival curves, Cox regression, and logistic regression were used in data analysis. A total of 5621 (1080 stage II and 4541 stage III) patients with median age of 72 years were included in this study. For stage II, 24.4% used 5-FU/LV, 31.2% used capecitabine, and 44.4% used FLOX/OX; the respective numbers for stage III were 13.8%, 17.9%, and 68.3%. Patients aged \u3c70 \u3eyears, not in the West region, not in Medicare state-buy-in program, and with no comorbidity were more likely to use FLOX/OX. FLOX/OX was associated with improved overall survival (OS) in stage II and III patients and improved cancer-specific survival in stage III patients compared with 5-FU/LV. The survival benefit of FLOX/OX was sustained in stage III patients aged ≥70 years. Capecitabine had the lowest ER/hospitalization rate with 19.2% in stage II and 28.9% in III. The use of FLOX/OX was associated with improved survival compared with 5-FU/LV among CC patients. Capecitabine was associated with the lowest ER/hospitalization rate

Real-World Patterns of Everolimus Use in Patients with Metastatic Breast Cancer

© AlphaMed Press 2020 Background: There is limited literature on patterns of everolimus use and subsequent hospitalizations and emergency room (ER) visits in real-world clinical practice. In this study, we describe patterns of everolimus use and hospitalizations and ER visits in a large cohort of patients with breast cancer (BC). Materials and Methods: Patients with BC treated with everolimus were identified in the MarketScan database from 2009 to 2016. The pattern of everolimus use and frequency of associated ER visits and hospitalizations during treatment (between the first claim and 30 days after the last claim for everolimus) were identified. Descriptive statistics and regression models were used. Results: A total of 3,556 everolimus users were identified (median age of 60 years; median days of use, 112). The initial prescribed dose was 10 mg in 74.8% of the patients. Compared with the initial dose, 23.5% of patients had a dose change. Forty-six percent of patients were hospitalized or had an ER visit during the treatment with everolimus. Age greater than 71, higher comorbidity score, treatment year prior to 2012, and lower initial dose were found to be significantly associated with ER visit/hospitalization in the regression models. Conclusions: A significant proportion of patients receiving everolimus had an ER visit or hospitalization during the use of everolimus. These results provide data regarding risks and benefits of treatment with everolimus. These results will be helpful in identifying patients at higher risk of hospitalizations or ER visits and facilitate evidence-based decision making to avoid serious complications. Implications for Practice: Everolimus, a mammalian target of rapamycin inhibitor, is approved in combination with exemestane in patients with hormone receptor–positive tumors previously treated with anastrozole or letrozole. As new drugs become available, it is crucial to understand the adverse events and potential complications associated with the use of such drugs in the general population, outside of the controlled clinical trial setting. This study describes the patterns of everolimus use and adverse events, including hospitalization and emergency room visits, in a large cohort of patients with metastatic breast cancer in routine practice
