Estimating the Undetected Burden of Respiratory Syncytial Virus Hospitalizations in Adults Through Capture-Recapture Methods.

INTRODUCTION: Traditional surveillance systems may underestimate the burden caused by respiratory syncytial virus (RSV). Capture-recapture methods provide alternatives for estimating the number of RSV-related hospitalizations in a population. METHODS: Capture-recapture methods were used to estimate the number of RSV-related hospitalizations in adults in Middle Tennessee from two independent hospitalization surveillance systems during consecutive respiratory seasons from 2016-2017 to 2019-2020. Data from the Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN) and the Emerging Infections Program (EIP) were used. Annual RSV hospitalization rates were calculated using the capture-recapture estimates weighted by hospitals' market share divided by the corresponding census population. RESULTS: Using capture-recapture methods, the estimated overall adult hospitalization rates varied from 8.3 (95% CI: 5.9-15.4) RSV-related hospitalizations per 10,000 persons during the 2016-2017 season to 28.4 (95% CI: 18.2-59.0) hospitalizations per 10,000 persons in the 2019-2020 season. The proportion of hospitalizations that HAIVEN determined ranged from 8.7% to 36.7% of the total capture-recapture estimated hospitalization, whereas EIP detected 23.5% to 52.7% of the total capture-recapture estimated hospitalizations. CONCLUSION: Capture-recapture estimates showed that individual traditional surveillance systems underestimated the hospitalization burden in adults. Using capture-recapture allows for a more comprehensive estimate of RSV hospitalizations.

Novel Integration of a Health Equity Immersion Curriculum in Medical Training.

Health disparities education is an integral and required part of medical professional training, and yet existing curricula often fail to effectively denaturalize injustice or empower learners to advocate for change. We discuss a novel collaborative intervention that weds the health humanities to the field of health equity. We draw from the health humanities an intentional focus retraining provider imaginations by centering patient narratives; from the field of health equity, we draw the linkage between stigmatized social identities and health disparities. We describe a longitudinal health equity curriculum for the Hospice and Palliative Medicine fellowship in Memphis, Tennessee, to give trainees exposure to the concept of structural violence and how it affects clinical care. The curriculum was developed in partnership with humanities and social sciences faculty who staff a Health Equity academic program at a small liberal arts college in Memphis. This curriculum has been implemented for the past four years in support of 22 hospice and palliative medicine fellows. Group debriefs and a mixed methods survey have revealed widespread and lasting impact towards understanding health equity concepts, enhanced communication and treatment of patients, and empowerment to address the broader needs and policies affecting patients and the communities in which they live. Ultimately, we model an educational initiative that integrates equity across the full scope of healthcare practice and equips learners with skills for sustaining compassionate practices, focusing on equity-oriented, person-centered care across the full scope of healthcare practice.

TennCare Disenrollment Led To Increased Eviction Filings And Evictions In Tennessee Relative To Other Southern States.

Previous research suggests that enrolling in Medicaid reduces evictions by improving health and providing financial protection. However, previous studies have not examined whether the loss of Medicaid affects eviction outcomes. We analyzed eviction filings and completed evictions after a large, mandatory Medicaid disenrollment in Tennessee in 2005. We conducted a difference-in-differences analysis using data from the Eviction Lab at Princeton University and found that relative to other southern states, the TennCare disenrollment led to a 27.6 percent greater increase in the average annual number of eviction filings at the county level during the period 2005-09 and a 24.5 percent greater increase in the average annual number of completed evictions at the county level during that same period. Our findings have implications for the housing stability of Medicaid recipients today, many of whom are being disenrolled because of the unwinding of the Medicaid continuous enrollment provision that is occurring across the country. To protect housing stability for people disenrolled from Medicaid, policy makers may wish to consider new initiatives aimed at preventing an increase in eviction.

Changing high-risk asthma in Memphis through partnership: Results from the CHAMP program.

BACKGROUND: Children in metro Shelby County, Tennessee, have disproportionally high asthma-related health care resource use (HRU) compared with those in other regions in Tennessee. OBJECTIVE: To describe the goals, logistics, and outcomes of the Changing High-Risk Asthma in Memphis through Partnership (CHAMP) program implemented to improve pediatric asthma care in Shelby County. METHODS: CHAMP established a multidisciplinary team with dedicated medical staff and community health workers, implemented a 24/7 call line to improve access to care, established a patient data registry to address fragmented care, assigned community health educators to improve asthma education and social needs, and partnered with services to address environmental triggers and social determinants of health. Patients eligible for CHAMP are Shelby County residents aged 2 to 18 years with high-risk asthma enrolled in Tennessee's Medicaid managed care program. Health care resource use outcomes 1-year pre- and post-CHAMP enrollment were analyzed for patients who had completed 1 year of CHAMP between January 2013 and December 2022. The 24/7 call line data between November 2013 and December 2022 were analyzed. RESULTS: CHAMP has enrolled 1348 children; 945 have completed 1 year (63% male; 90% identified as Black). At 1-year post-CHAMP enrollment, patients had 58%, 68%, 42%, and 53% reductions in emergency department visits, inpatient and observation visits, urgent care visits, and total asthma exacerbations, respectively. The number of asthma exacerbations per patient significantly decreased from 2.97 to 1.40 at 1-year post-CHAMP enrollment. Of the calls made to the 24/7 call line, 58% occurred after hours and 52% led to issue resolution without a medical facility visit. CONCLUSION: CHAMP successfully decreased asthma HRU in children with high-risk asthma in Shelby County by implementing initiatives that targeted barriers to asthma care.

An examination of geographic access to outpatient stroke rehabilitation services in Tennessee, a stroke belt state.

BACKGROUND: While over half of US stroke patients were discharged to home, estimates of geographic access to outpatient stroke rehab facilities are unavailable. The objective of our study was to assess distance and travel time to the nearest outpatient stroke rehab facility in Tennessee, a high stroke prevalence state. METHODS: We systematically scraped Google Maps with the terms "stroke", "rehabilitation", and "outpatient" to identify Tennessee stroke rehab facilities. We then averaged/aggregated Census block-level travel distance and travel time to determine the mean travel distance/time to a facility for each of the 95 Tennessee counties and the overall state. Comparisons of mean travel time/distance were made between rural and urban counties and between low, medium, and high stroke prevalence counties. RESULTS: We found that 79% of facilities were in urban areas. Significantly higher median of mean travel times and distances (p values both <0.001) were observed in rural (22.0 miles, 31.6 min) versus urban counties (10.5 miles, 18.4 min). High (21.5 miles, 32.5 min) and medium (18.7 miles, 28.3 minutes) stroke prevalence counties, which often overlap with rural counties, had significantly higher median of mean travel times and distance than low stroke prevalence counties (7.3 miles, 14.5 min). CONCLUSIONS: Rural Tennessee counties were faced with high stroke prevalence, inadequate facilities, and significantly greater travel distance and time to access care. Additional efforts to address transportation barriers and accelerate telerehabilitation implementation are crucial for improving equal access to stroke aftercare in these areas.

Perceptions of access to care after a rural hospital closure in an economically distressed county of Appalachian Tennessee.

PURPOSE: The rise in rural hospital closures has sparked concern about the potential loss of essential health care services for rural communities. It is crucial to incorporate the perspectives of community residents, which have been largely missing from the literature, when devising strategies to improve health care for this population. The purpose of this study was to describe community residents' perceptions of access to care following a rural hospital closure in an economically distressed Appalachian county of Tennessee. METHODS: This study used a qualitative descriptive approach to illustrate how community residents perceive accessing care post hospital closure. We conducted semi-structured interviews with 24 community residents via telephone in May through August of 2020. Interviews were analyzed using conventional content analysis. FINDINGS: Five themes were identified based on Penchansky and Thomas' framework of health care: accessibility, availability, affordability, accommodation, and acceptability. Accessibility was identified as the most common concern among participants. Specifically, participants perceived longer travel times to receive care, reduced availability of emergency and specialty care, increased costs associated with ambulance services, and extended wait times to see providers. CONCLUSIONS: Our findings provide a critical perspective to inform local leaders and policymakers on the impacts of a hospital closure in a rural community. As rural hospitals continue to close, it is crucial to develop multi-level, community-driven solutions to ensure access to care for rural communities.

East Tennessee older women's perceptions of Medicare, Medicaid, and related health policies.

Older women face unique challenges regarding health disparities. This study aims to provide an understanding of older women's perceptions and situated experiences regarding the gendered health disparities they face, which are characterized by the policies related to older women's health and the geopolitical and social norms in which they live. The purpose of this project is to provide policy and decision-makers with insights and a better understanding of older women's experiences and perceptions of the policies that impact their health and healthcare. The data for this study was collected through semi-structured interviews with twelve women in Appalachian East Tennessee. Areas examined include: the women's perceived impact of federal, state, and local policies on the participants, particularly of Medicare and Medicaid; the role of social norming and health narratives, particularly stigmatization, discrimination, and health marginalization of older women; and the role of place and place-based drivers on these areas. This study sought to determine if these factors impact the participants' awareness or lack of awareness of policies related to older women. Findings showed that older women in East Tennessee lacked knowledge of health policies, that older women perceive systemic and individual discrimination in policymaking, clinical care, and health research, and that they perceive that place-based drivers have impacted their access to healthcare. These findings have implications for policymaking and intervention design in co-production with older women in order to mitigate older women's health disparities.

The Teledermatology Experience: Cost Savings and Image Quality Control.

Introduction: Teledermatology adoption continues to increase, in part, spurred by the COVID-19 pandemic. This study analyzes the utility and cost savings of a store-and-forward teledermatology consultative system within the Veterans Health Administration (VA). Methods: Retrospective cohort of 4,493 patients across 14 remote sites in Tennessee and Kentucky from May 2017 through August 2019. The study measured the agreement between the teledermatology diagnoses and follow-up face-to-face clinic evaluations as well as the cost effectiveness of the teledermatology program over the study period. Results: Fifty-four percent of patients were recommended for face-to-face appointment for biopsy or further evaluation. Most patients, 80.5% received their face-to-face care by a VA dermatologist. There was a high level of concordance between teledermatologist and clinic dermatologist for pre-malignant and malignant cutaneous conditions. Veterans were seen faster at a VA clinic compared with a community dermatology site. Image quality improved as photographers incorporated teledermatologist feedback. From a cost perspective, teledermatology saved the VA system $1,076,000 in community care costs. Discussion: Teledermatology is a useful diagnostic tool within the VA system providing Veteran care at a cost savings.

Incarceration, Inequality, and Hepatitis C Treatment: The Story of Two Southern States.

Hepatitis C virus (HCV) infection causes liver-related morbidity/mortality and disproportionately affects people who are incarcerated and non-Hispanic Black populations, largely due to social and policy issues that contribute to poor health. With the advent of highly efficacious treatment, HCV is now curable. However, most states' departments of corrections do not offer universal HCV testing or treatment. Two southern states-Tennessee and Louisiana-provide examples of divergent approaches to addressing HCV infection. While Tennessee has offered treatment on a limited basis, resulting in a class action lawsuit, the state of Louisiana recently adopted a new approach. In establishing the 2019 Hepatitis Elimination Plan, the state created a standard of care for HCV infection that included robust testing and treatment in state prison facilities while capping costs. Louisiana has demonstrated the feasibility of HCV testing and treatment programs within state prisons, an important step towards achieving health equity.

Screening for the high-need population using single institution versus state-wide admissions discharge transfer feed.

BACKGROUND: Access to programs for high-needs patients depending on single-institution electronic health record data (EHR) carries risks of biased sampling. We investigate a statewide admission, discharge, and transfer feed (ADT) in assessing equity in access to these programs. METHODS: This is a retrospective cross-sectional study. We included high-need patients at Vanderbilt University Medical Center (VUMC) 18 years or older, with at least three emergency visits (ED) or hospitalizations in Tennessee from January 1 to June 30, 2021, including at least one at VUMC. We used the Tennessee ADT database to identify high-need patients with at least one VUMC ED/hospitalization. Then, we compared this population with high-need patients identified using VUMC's Epic® EHR database. The primary outcome was the sensitivity of VUMC-only criteria for identifying high-need patients compared to the statewide ADT reference standard. RESULTS: We identified 2549 patients with at least one ED/hospitalization and assessed them as high-need based on the statewide ADT. Of those, 2100 had VUMC-only visits, and 449 had VUMC and non-VUMC visits. VUMC-only visit screening criteria showed high sensitivity (99.1%, 95% CI: 98.7 - 99.5%), showing that the high-needs patients admitted to VUMC infrequently access alternative systems. Results showed no meaningful difference in sensitivity when stratified by patient's race or insurance. CONCLUSIONS: ADT allows examination for potential selection bias when relying upon single-institution utilization. In VUMC's high-need patients, there's minimal selection bias when depending on same-site utilization. Further research must understand how biases vary by site and durability over time.

Using Geographic Information Systems in health disparities research: Access to care considerations.

In health disparities research, Geographic Information Systems (GIS) provide nurse researchers with powerful tools to incorporate spatial factors, such as access to care and related attributes like socioeconomic and environmental characteristics, into their studies. This article educates nurse scientists about GIS-based research benefits and considerations (focusing on access-to-care factors) and the influence of various access-to-care metrics on research outcomes. We present an overview of GIS in nursing and health disparities research, along with findings from our 2022 study examining access to care's relationship with county-level mortality rates in Tennessee, especially in areas where rural hospitals closed between 2010 and 2019. We highlight three distinct access-to-care measures (Euclidean distances and road network-based travel times based on county and census tract centroids), showcasing how different calculations impact our modeling results. Our results underscore the importance of understanding the choice of access-to-care metrics in GIS-based research to draw valid conclusions.

The Social Determinants of Health Among Lesbian, Gay, Bisexual, and Transgender (LGBT) Adults in Nashville, Tennessee.

Lesbian, gay, bisexual, and transgender (LGBT) populations experience widespread disparities in health outcomes, health behaviors, and access to care compared to their non-LGBT counterparts. Moreover, very few studies have either studied the social determinants of health (SDoH) of LGBT populations or LGBT health in large cities located in the US South. This study uses novel, community-informed, and representative data to study the SDoH of LGBT adults in Nashville and Davidson County, Tennessee. Compared to non-LGBT adults (n = 1583), LGBT adults (n = 128) in Nashville, Tennessee, were more likely to report being dissatisfied with life and feeling emotionally upset or physical symptoms as a result of how they were treated based on their race/ethnicity compared to non-LGBT adults. LGBT adults in Nashville were also less likely to keep a firearm in the home than their non-LGBT peers. This study documents new disparities in the SDoH for LGBT adults living in one of the largest and fastest growing cities in the southeastern US. More research on LGBT populations in urban centers located in the US South is critically needed. Meanwhile, locally based community organizations and public health leaders may consider developing and testing innovative solutions to enhance social networks and social supports among LGBT populations. Addressing the SDoH among LGBT adults in southern cities will be essential for achieving health equity for all LGBT populations in the USA.

Reductions and pronounced regional differences in morphine distribution in the United States.

OBJECTIVES: The purpose of this longitudinal study was to describe the temporal pattern of morphine distribution nationally and between states. METHODS: Drug weight was obtained from Report 5 of the US Drug Enforcement Administration's Automation of Reports and Consolidated Orders System (ARCOS) to characterize patterns in the distribution of morphine from 2012 to 2021. Morphine distribution amounts were separated by state and business type and corrected for population. States outside a 95% confidence interval relative to the national average were considered statistically significant. KEY FINDINGS: In 2012, there was a 4.6-fold difference in morphine distribution between the highest-prescribing state, Tennessee (180.2 mg/person), and the lowest-prescribing state, Texas (39.4 mg/person). By the end of 2021, national distribution of morphine had decreased by 59.9% when compared to the peak year 2012. In 2021, Tennessee (51.1 mg/person) remained the highest-prescribing state with a 3.0-fold difference relative to Texas (17.2 mg/person). The average hospital decrease (-73.9%) from 2012 to 2021 was larger than that of pharmacies (-58.2%). CONCLUSIONS: The national 59.9% decline in morphine in the last decade may be attributable to prioritization of the US opioid crisis as a public concern. Further research is necessary to understand the persistent regional difference between states.

Working With Rural Producers to Expand EBT in Farmers' Markets: A Case Study in Hardeman County, Tennessee.

Rural residents tend to eat less fruits and vegetables, placing them at higher risk of chronic diseases compared with urban residents. Farmers' markets can provide increased access to fresh produce for rural communities. Encouraging markets to accept Supplemental Nutrition Assistance Program (SNAP) benefits through Electronic Benefit Transfer (EBT) can expand access to healthy foods to low-income residents. Rural markets are less likely to accept SNAP compared with urban markets. Rural producers have identified lack of knowledge and limited support about the application process as barriers for accepting SNAP. This case study details how our Extension program helped a rural producer through the SNAP application process. We started with a workshop to inform rural producers about the benefits of accepting SNAP. After the workshop, we provided hands-on support and assistance to help one producer navigate the EBT application process as well as how to implement and advertise SNAP at the market. Implications for practitioners about tips to help producers overcome challenges and barriers for EBT acceptance are discussed.

Association between Financial Barriers to Healthcare Access and Mental Health Outcomes in Tennessee.

OBJECTIVES: A large number of people cannot afford healthcare services in the United States. Researchers have studied the impact of lack of affordability of health care on the outcomes of various physical conditions. Mental health disorders have emerged as a major public health challenge during the past decade. The lack of affordability of health care also may contribute to the burden of mental health. This research focuses on the association between financial barriers to health care and mental health outcomes in the US state of Tennessee. METHODS: We used cross-sectional data contained in the 2019 US Behavioral Risk Factor Surveillance System (BRFSS). We extracted data for the state of Tennessee, which included 6242 adults aged 18 years or older. Multinomial regression analyses were conducted to test the association between not being able to see a doctor with the number of mentally unhealthy days during the past month. We coded the outcome as a three-level variable, ≥20 past-month mentally unhealthy days, 1 to 20 past-month mentally unhealthy days, and 0 past-month mentally unhealthy days. The covariates examined included self-reported alcohol use, self-reported marijuana use, and other demographic variables. RESULTS: Overall, 11.0% of participants reported ≥20 past-month mentally unhealthy days and 24.0% reported 1 to 20 past-month mentally unhealthy days. More than 13% of study participants reported they could not see a doctor because of the cost in the past 12 months. The inability to see a doctor because of the cost of care was associated with a higher risk of ≥20 past-month mentally unhealthy days (relative risk ratio 3.18; 95% confidence interval 2.57-3.92, P < 0.001) and 1 to 19 past-month mentally unhealthy days (relative risk ratio 1.94; 95% confidence interval 1.63-2.32, P < 0.001). CONCLUSIONS: Statistically significant associations were observed between the inability to see a doctor when needed because of cost and increased days of poorer mental health outcomes. This research has potential policy implications in the postcoronavirus disease 2019 era with healthcare transformation and significant financial impact.

A Novel Preoperative Patient Survey Predicts Adverse Patient Outcomes-Implementation and Preliminary Results of the Tennessee Preoperative Assessment Tool.

BACKGROUND: Accurate preoperative risk stratification remains elusive. Existing tools are often missing important patient-reported and functional factors. We sought to implement a novel tool, with dynamic functional data and comorbidity variables, to define factors which predict postoperative outcomes. MATERIALS AND METHODS: We expanded a previously validated functional questionnaire to create the Tennessee Preoperative Assessment Tool (TPAT). Unique elements included change in functional status, usual and best activity tolerance, and development of new conditions. The survey was administered to all new patients seen in several surgery clinics from July 2021 to June 2022. RESULTS: A total of 1950 patients completed the survey. Of the completed surveys, 197 patients underwent an elective, inpatient, abdominal surgery and were included in the study. Several patient-reported factors were associated with poor postoperative outcomes. For example, decrease in functional activity in the previous 60 days (n = 50; 25.4%) was a strong predictor of poor postoperative outcomes including readmission (30-day: 8.8% vs .0%; P = .034), wound dehiscence (12.0% vs 3.4%; P = .022), blood transfusion (6.0% vs .0%; P = .003), sepsis (4.0% vs .0%; P = .015), and wound infection (18.0% vs 6.8%; P = .076). DISCUSSION: In this preliminary implementation study, patients undergoing elective, inpatient, abdominal surgery, utilization of a novel, patient-reported survey tool proactively identifies patients at risk of clinically relevant postoperative outcomes. Patient-reported decreased activity in the 60 days prior to surgeon evaluation was associated with several adverse postoperative outcomes. Additionally, this study demonstrates that the TPAT can be seamlessly integrated into the usual clinical workflow and is hypothesis generating for future interventional studies.

Kurdish Refugee Beliefs about Mental Health and Help-Seeking: A Community-Engaged Research Study in Tennessee.

Refugee populations exhibit high rates of PTSD, anxiety, depression, and psychological distress, but are less likely to receive care than the general population. Perceptions among the Kurdish refugee community about causes and consequences of mental illness symptoms and perceived barriers to help-seeking are understudied. This community-engaged research study conducted in-depth interviews with Kurdish refugees from Iraq to explore their beliefs about drivers of mental illness and seeking help for mental health. Iterative thematic analysis of transcripts from ten participants indicated four key themes: (1) social network loss due to resettlement causes poor mental health; (2) socioeconomic status loss due to unrecognized professional qualifications puts strain on mental health; (3) social stigma about mental health and fears about disclosure of mental health issues within community and subsequent negative gossip prevent help-seeking; and (4) social interaction may alleviate mental illness symptoms. Overall, Kurdish refugees perceived social factors as major drivers of mental illness symptoms and barriers to help-seeking in their community. However, while participants believed that the general community attitude was against help-seeking, most participants personally expressed support of anyone in their community needing to see a mental health professional. Future research should assess the extent to which perceived community norms differ from aggregated personal help-seeking attitudes and behaviors among Kurdish refugees from Iraq in the United States.

Developing and Validating a Novel Tool to Enhance Functional Status Assessment: The Tennessee Functional Status Questionnaire (TFSQ).

PURPOSE: Functional status is a major contributor to overall health and reflects both daily activity level (performance) and maximum attainable activity level (capacity). Existing assessment tools evaluate only 1 domain of function and do not provide insight into contributors to functional decline. We addressed these deficiencies by developing the Tennessee Functional Status Questionnaire (TFSQ), which reports activity levels in metabolic equivalents (METs) and evaluates 5 key areas: performance, capacity, activity, pain, and acute care. We validated the activity levels reported by the TFSQ against the Duke Activity Status Index (DASI). METHODS: In this prospective, observational study, 120 patients completed both the TFSQ and the DASI. TFSQ-reported functional performance and capacity was correlated with DASI-calculated METs. RESULTS: Pearson correlation between TFSQ-reported capacity and DASI-calculated METs was r = 0.69, P < .001. TFSQ capacity was significantly lower in patients who reported recently decreased activity, pain affecting function, or recent acute care exposure. CONCLUSIONS: The TFSQ is a brief and efficient assessment of patient function, standardized to METs and validated against the DASI. Our study suggests that many patients may have the functional reserve to increase daily physical activity and that factors such as changes in activity, pain, and recent acute care interaction may lower functional capacity.

Mortality among Tennessee Eastman Corporation (TEC) uranium processing workers, 1943-2019.

BACKGROUND: There are few occupational studies of women exposed to ionizing radiation. During World War II, the Tennessee Eastman Corporation (TEC) operated an electromagnetic field separation facility of 1152 calutrons to obtain enriched uranium (235U) used for the Hiroshima atomic bomb. Thousands of women were involved in these operations. MATERIALS AND METHODS: A new study was conducted of 13,951 women and 12,699 men employed at TEC between 1943 and 1947 for at least 90 days. Comprehensive dose reconstruction techniques were used to estimate lung doses from the inhalation of uranium dust based on airborne measurements. Vital status through 2018/2019 was obtained from the National Death Index, Social Security Death Index, Tennessee death records and online public record databases. Analyses included standardized mortality ratios (SMRs) and Cox proportional hazards models. RESULTS: Most workers were hourly (77.7%), white (95.6%), born before 1920 (58.3%), worked in dusty environments (57.0%), and had died (94.9%). Vital status was confirmed for 97.4% of the workers. Women were younger than men when first employed: mean ages 25.0 years and 33.0 years, respectively. The estimated mean absorbed dose to the lung was 32.7 mGy (max 1048 mGy) for women and 18.9 mGy (max 501 mGy) for men. The mean dose to thoracic lymph nodes (TLNs) was 127 mGy. Statistically significant SMRs were observed for lung cancer (SMR 1.25; 95% CI 1.19, 1.31; n = 1654), nonmalignant respiratory diseases (NMRDs) (1.23; 95% CI 1.19, 1.28; n = 2585), and cerebrovascular disease (CeVD) (1.13; 95% CI 1.08, 1.18; n = 1945). For lung cancer, the excess relative rate (ERR) at 100 mGy (95% CI) was 0.01 (-0.10, 0.12; n = 652) among women, and -0.15 (-0.38, 0.07; n = 1002) among men based on a preferred model for men with lung doses <300 mGy. NMRD and non-Hodgkin lymphoma were not associated with estimated absorbed dose to the lung or TLN. CONCLUSIONS: There was little evidence that radiation increased the risk of lung cancer, suggesting that inhalation of uranium dust and the associated high-LET alpha particle exposure to lung tissue experienced over a few years is less effective in causing lung cancer than other types of exposures. There was no statistically significant difference in the lung cancer risk estimates between men and women. The elevation of certain causes of death such as CeVD is unexplained and will require additional scrutiny of workplace or lifestyle factors given that radiation is an unlikely contributor since only the lung and lymph nodes received appreciable dose.
