Cancer-Directed Therapy and Hospice Care for Metastatic Cancer in American Indians and Alaska Natives.

ABSTRACT:

Background

Little has been reported regarding patterns of oncologic care in American Indian/Alaska Natives (AI/AN). Observed worse survival has been attributed to later-stage presentation. We aimed to evaluate racial differences in cancer-directed therapy and hospice care utilization in AI/ANs and non-Hispanic whites (NHW) with metastatic cancer.

Methods

The linked Surveillance, Epidemiology, and End Results (SEER)-Medicare claims database was accessed for AI/AN and NHW metastatic-cancer cases diagnosed between 2001 and 2007. Utilization of cancer-directed therapy (surgery, radiation, and/or chemotherapy) and/or hospice services was compared between AI/ANs and NHWs. Minimally adjusted (age, sex, diagnosis year) and fully-adjusted (also Klabunde comorbidity score, sociodemographic factors) regression models were used to estimate odds (OR) and hazard ratios (HR) for receipt of care.

Results

AI/ANs were younger, more likely to reside in the West, be unmarried, have lower income, and live in a nonurban setting than NHWs. Fewer AI/ANs received any cancer-directed therapy (57% vs. 61% NHWs) within 3 months of diagnosis; sociodemographic factors accounted for much of this difference [fully-adjusted HR, 0.94; 95% confidence interval (CI), 0.83-1.08]. We noted differences in hospice utilization between AI/ANs (52%) and NHWs (61%). A significant difference in hospice utilization remained after adjustment for sociodemographics (OR, 0.78; 95% CI, 0.61-0.99).

Conclusion

Observed absolute differences in care for AI/ANs and NHWs with metastatic cancer were largely accounted for by adjusting for socioeconomics, comorbidities, and demographic factors. A significant association between race and hospice utilization was noted.

Impact

Efforts to improve metastatic-cancer care should focus on socioeconomic barriers and investigate the observed disparity in receipt of hospice services.

Project description:BackgroundIn the United States, the mortality burden of injury is higher among American Indians and Alaska Natives (AI/AN) than any other racial/ethnic group, and injury contributes to considerable medical costs, years of potential life lost (YPLL), and productivity loss among AI/AN.This study assessed the economic burden of injuries for AI/AN who are eligible for services through Indian Health Service, analyzing direct medical costs of injury for Indian Health Service's users and years of potential life lost (YPLL) and the value of productivity losses from injury deaths for AI/AN in the Indian Health Service population.MethodsInjury-related lifetime medical costs were estimated for Indian Health Service users with medically treated injuries using data from the 2011-2015 National Data Warehouse. Productivity costs and YPLL were estimated using data on injury-related deaths among AI/AN in Indian Health Service's 2008-2010 service population. Costs were reported in 2017 U.S. dollars.ResultsThe total estimated costs of injuries per year, including injuries among Indian Health Service users and productivity losses from injury-related deaths, were estimated at $4.5 billion. Lifetime medical costs to treat annual injuries among Indian Health Service users were estimated at $549 million, with the largest share ($131 million) going toward falls, the most frequent injury cause. Total estimated YPLL from AI/AN injury deaths in Indian Health Service's service population were 106,400. YPLL from injury deaths for men (74,000) were 2.2 times YPLL for women (33,000). Productivity losses from all injury-related deaths were $3.9 billion per year. The highest combined lifetime medical and mortality costs were for motor vehicle/traffic injuries, with an estimated cost of $1.6 billion per year.ConclusionsFindings suggest that targeted injury prevention efforts by Indian Health Service likely contributed to lower rates of injury among AI/AN, particularly for motor vehicle/traffic injuries. However, because of remaining disparities in injury-related outcomes between AI/AN and all races in the United States, Indian Health Service should continue to monitor changes in injury incidence and costs over time, evaluate the impacts of previous injury prevention investments on current incidence and costs, and identify additional injury prevention investment needs.

Project description:BackgroundAmerican Indians/Alaska Natives have the highest commercial tobacco use in the United States, resulting in higher tobacco-caused deaths and diseases than the general population. Some American Indians/Alaska Natives use commercial tobacco for ceremonial as well as recreational uses. Because federally recognized Tribal lands are sovereign, they are not subject to state cigarette taxes and smoke-free laws. This study analyzes tobacco industry promotional efforts specifically targeting American Indians/Alaska Natives and exploiting Tribal lands to understand appropriate policy responses in light of American Indians'/Alaska Natives' unique sovereign status and culture.MethodsWe analyzed previously secret tobacco industry documents available at the Truth Tobacco Documents Library (https://industrydocuments.library.ucsf.edu/tobacco/).ResultsTobacco companies used promotional strategies targeting American Indians/Alaska Natives and exploiting Tribal lands that leveraged the federally recognized Tribes' unique sovereign status exempting them from state cigarette taxes and smoke-free laws, and exploited some Tribes' existing traditional uses of ceremonial tobacco and poverty. Tactics included price reductions, coupons, giveaways, gaming promotions, charitable contributions, and sponsorships. In addition, tobacco companies built alliances with Tribal leaders to help improve their corporate image, advance ineffective Youth Smoking Prevention programs, and defeat tobacco control policies.ConclusionsThe industry's promotional tactics likely contribute to disparities in smoking prevalence and smoking-related diseases among American Indians//Alaska Natives. Proven policy interventions to address these disparities including tobacco price increases, cigarette taxes, comprehensive smoke-free laws, and industry denormalization campaigns to reduce smoking prevalence and smoking-related disease could be considered by Tribal communities. The sovereign status of federally recognized Tribes does not prevent them from adopting these measures.ImplicationsAmerican Indians/Alaska Natives suffer disparities in smoking prevalence and smoking-related diseases as compared with other groups. The tobacco industry has used promotional tactics including price reductions, coupons and giveaways, casino and bingo promotions, charitable contributions and sponsorships, and so-called Youth Smoking Prevention (YSP) programs to specifically target American Indians/Alaska Natives and exploit Tribal sovereignty, which likely contribute to disparities in tobacco use and related diseases and deaths among this population. Tribal and public health policy makers should consider rejecting ineffective YSP programs and instead consider adopting proven policy interventions including tobacco price increases, cigarette and casino taxes, comprehensive smokefree laws, and anti-industry denormalization campaigns to reduce smoking and smoking-related disease.

Project description:BackgroundSeveral studies have shown racial disparities in lung cancer care in the United States in the Black and Hispanic populations but not many have included American Indian/Alaska Native (AI/AN) patients. We retrospectively evaluated the factors associated with receipt of guideline-concordant care in AI/AN and non-Hispanic White (NHW) patients with stage I non-small cell lung cancer (NSCLC) and describe the relationship between guideline-concordant care and survival outcomes in these populations.MethodsUsing the National Cancer Database, we identified NHW and AI/AN patients diagnosed with stage I NSCLC between 2004 and 2017. We evaluated the utilization of anatomic resection among both NHW and AI/AN and described the variables associated with anatomic resection. We also evaluated 5-year overall survival (OS) by treatment and race. We used the chi-square test, multivariable analysis, and the Kaplan-Meier method for statistical analysis.ResultsWe identified 196,349 patients. Of these, 195,736 (99.69%) were NHW and 613 (0.31%) were AI/AN. Relative to NHW, AI/AN were more frequently diagnosed at a younger age (40% vs. 28% diagnosed at 18-64 years of age; P<0.001) and more commonly resided in rural areas (14% vs. 5%; P<0.001). In our multivariable analysis adjusting for all patient factors [age at diagnosis, sex, race, residence location, Charlson Comorbidity Index (CCI), tumor stage, lymph node status, and treatment facility], AI/AN patients were less likely to undergo anatomic resection than NHW patients [odds ratio (OR), 0.74; 95% confidence interval (CI): 0.62-0.89]. In our unadjusted survival analysis, AI/AN patients had lower 5-year OS than NHW (58% vs. 56%; P=0.04). When adjusted for surgery this difference was no longer significant.ConclusionsAI/AN patients with stage I NSCLC undergo anatomic resection less frequently than do NHW, with lower 5-year OS than NHW. However, this survival difference is mitigated when AI/AN undergo anatomic resection.
